Dewayne missed four of the 30 problems on the problem set. What
percent of the problems did Dewayne answer correctly?
Answer:
75% correct
Step-by-step explanation:
To get the 10% discount, a shopper must spend at least $400.
Use d to represent the spending (in dollars) of a shopper who gets the discount.
The shopper must spend at least $444.44 to get the 10% discount.
Step-by-step explanation:If a shopper gets a 10% discount, it means they pay only 90% of the original price. Let's say the original spending is represented by x. Then the spending after the 10% discount would be:
d = 0.9x
Now, we know that the shopper must spend at least $400 to get the discount, so we can set up an inequality:
d ≥ 400
Substituting the expression we found for d, we get:
0.9x ≥ 400
Dividing both sides by 0.9, we get:
x ≥ 444.44
So the shopper must spend at least $444.44 to get the 10% discount.
Mars candy company is testing one of its machines in the factory to make sure it is producing more than 98% high-quality candy (H0: p = 0. 98; Ha: p > 0. 98; α = 0. 05). The test results in a p-value of 0. 15. However, the company is unaware that it is actually producing 99% high-quality candy. What MOST likely happens as a result of the testing?
A. The company rejects H0, making a Type I error.
B. The company fails to reject H0, making a Type II error.
C. The company rejects H0, making a Type II error.
D. The company fails to reject H0, making a Type I error.
E. The company rejects H0 correctly
the correct answer is option C: The company rejects H0, making a Type II error. In this hypothesis test, the null hypothesis H0 is that the machine produces no more than 98% high-quality candy, and the alternative hypothesis Ha is that the machine produces more than 98% high-quality candy. The significance level is α = 0.05.
The p-value is the probability of obtaining a test statistic as extreme or more extreme than the observed test statistic, assuming that the null hypothesis is true. A p-value of 0.15 is greater than the significance level of 0.05, which means that the result is not statistically significant.
However, the company is unaware that the machine is actually producing 99% high-quality candy. This means that the null hypothesis is actually false, and the alternative hypothesis is true. In other words, the machine is producing more than 98% high-quality candy.
Based on these observations, the company failing to reject the null hypothesis (option B) would be a Type II error, as it would mean that the company is not detecting a significant difference in the candy quality when, in fact, the machine is producing candy of higher quality than the null hypothesis assumes.
Therefore, the correct answer is option C: The company rejects H0, making a Type II error.

At a basketball game, an air cannon launches T-shirts into the crowd. The function y=−18x2+4x
represents the path of a T-shirt. The function 3y=2x−14
represents the height of the bleachers. In both functions, y
represents vertical height (in feet) and x
represents horizontal distance (in feet). At what height does the T-shirt land in the bleachers?
The height that the T-short lands on the bleachers is x = 0.65.
What is quadratic formula?The quadratic equation may be solved by adding and subtracting the same number within the parenthesis to get a perfect square trinomial, which is how the quadratic formula is obtained. A version of the equation that can be solved using the square root function is the result of this method.
Given that it can be used to solve any quadratic equation regardless of the values of the variables a, b, and c, the quadratic formula is an effective tool for solving quadratic equations.
The equation of the path of T-shirt is y = -18x² + 4x and that of the height of bleachers is 3y=2x−14 or y = 2/3x - 14/3
To find the height of the T-shirt landing we find the intersection of the two equations as follows:
-18x² + 4x = (2x - 14)/3
-54x² + 12x = 2x - 14
54x² - 10x - 14 = 0
27x² - 5x - 7 = 0
Using the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
Substitute the values;
x = (-(-5) ± √((-5)² - 4(27)(-7))) / 2(27)
x = (5 ± √(925)) / 54
x = (5 ± 5√37) / 54
x = (5 + 5√37) / 54 = 0.65 and
x = (5 - 5√37) / 54 = -0.47
Hence, the height that the T-short lands on the bleachers is x = 0.65.

Answer:
To factorize the quadratic expression f² + 7f + 10, we need to find two numbers that multiply to 10 and add up to 7. These numbers are 2 and 5. So, we can write:
f² + 7f + 10 = (f + 2)(f + 5)
Therefore, the answer is (f + 2)(f + 5).
Answer:
Step-by-step explanation:
[tex]f^2+7f+10=f^2+2f+5f+10=f(f+2)+5(f+2)=(f+5)(f+2)[/tex]
By grouping, we can factor the polynomial. We know that 2+5=7 and 2*5=10, so this is why (f+5) and (f+2) are factors of f²+7f+10.
Serenity and her children went into a restaurant and will buy hamburgers and tacos. Each hamburger costs $5.50 and each taco costs $2. Serenity has a total of $45 to spend on hamburgers and tacos. Write an inequality that would represent the possible values for the number of hamburgers purchased, ℎ h, and the number of tacos purchased, � . t.
Answer: Less than or equal to 45
Step-by-step explanation:
Let's use algebra to write the inequality.
Let h be the number of hamburgers purchased and t be the number of tacos purchased.
Each hamburger costs $5.50 and each taco costs $2, so the total cost of h hamburgers and t tacos is:
5.5h + 2t
Serenity has a total of $45 to spend, so we can write:
5.5h + 2t ≤ 45
This is the inequality that represents the possible values for the number of hamburgers purchased, h, and the number of tacos purchased, t.
Note that the inequality is less than or equal to 45, since Serenity cannot spend more than $45.
To represent the possible values for the number of hamburgers and tacos purchased, an Inequality can be written as 5.5x + 2y ≤ 45.
To write an inequality to represent the possible values for the number of hamburgers purchased (h) and the number of tacos purchased (t), we need to consider the cost of each item and the total amount Serenity has to spend.
Let's assume Serenity buys x hamburgers and y tacos. Each hamburger costs $5.50, so the total cost of hamburgers purchased would be 5.5x. Each taco costs $2, so the total cost of tacos purchased would be 2y.
The total amount Serenity has to spend is $45. Therefore, the inequality that represents the possible values for h and t is: 5.5x + 2y ≤ 45.

a. What does the y-intercept tell you in this situation?
Type your response in the space below.
The y-intercept for this situation shows that the speed of the ship sailing is 0 miles per second during the time t = 4 seconds, after that the speed keeps on decreasing.
Explain about the negative acceleration?Look into the fact that the vector of acceleration points in the same general direction as the vector of velocity change. This indicates that whether you add to or subtract from the velocity depends on the direction of the acceleration.
According to mathematics, a negative acceleration indicates that the velocity will be subtracted from, while a positive acceleration indicates that the velocity will be increased. If the velocity had become negative to begin with, subtracting as from value may make an object move faster since the magnitude would grow.The graph is shown for the distance travelled by the ship with time by Clare.
Thus, the y-intercept for this situation shows that the speed of the ship sailing is 0 miles per second during the time t = 4 seconds, after that the speed keeps on decreasing.

andrew is buying a cell phone that has a regular price of $485. the cell phone is on sale for 35% off the regular price. what will be the sale price?
the sale price of the cell phone after the 35% discount is $315.25.
How to solve and what is sale?
To find the sale price of the cell phone, we need to apply the discount of 35% to the regular price of $485. We can do this by multiplying the regular price by 0.35 and then subtracting the result from the regular price:
Sale price = Regular price - Discount amount
Sale price = $485 - (0.35 x $485)
Sale price = $485 - $169.75
Sale price = $315.25
Therefore, the sale price of the cell phone after the 35% discount is $315.25.
A sale is a temporary reduction in the price of a product or service. Sales are often used by businesses to attract customers and increase sales volume. Sales can be offered for many reasons, such as to clear out inventory, promote a new product, or attract customers during a slow period.
In a sale, the price of a product or service is discounted, either by a fixed amount or by a percentage of the regular price. For example, a store might offer a 20% discount on all clothing items, or a car dealership might offer a $5,000 discount on a particular model of car.

New width w'$ is 75% of the original width w. Therefore, the width of the land is reduced by 25%, just like the area.
How to find reduced area?The area of the tennis court is given by:
A = lw
where l is the length of the court and w is the width of the court.
Substituting the given values, we have:
[tex]$$260.7569 = l \cdot 10.97$$[/tex]
Solving for l, we get:
[tex]$l = \frac{260.7569}{10.97} \approx 23.76 \text{ m}$$[/tex]
To find the area of the court without the white bands, we need to subtract the areas of the two white bands from the total area. Since the white bands are on the top and bottom, we need to subtract twice the product of the width of the court and the width of the white band. The width of the white band is not given, but we know that the width of the court will be reduced by 25%, so the new width of the court will be:
w' = w - 0.25w = 0.75w
Substituting the given values, we have:
[tex]$$\begin{aligned}A' &= lw' - 2(0.75w)(l) \ &= l(0.75w) - 1.5wl \ &= 0.5625lw\end{aligned}$$[/tex]
where A' is the new area of the court without the white bands. Substituting the values of l and w that we found earlier, we have:
[tex]$$A' = 0.5625 \cdot 23.76 \cdot 10.97 \approx 146.17 \text{ m}^2$$[/tex]
Therefore, the new area of the court is reduced by 25%.
To find out if the width of the land is also reduced by 25%, we need to compare the original width w with the new width w'. We have:
[tex]$w' = 0.75w$$[/tex]
Dividing both sides by w, we get:
[tex]$\frac{w'}{w} = 0.75$$[/tex]
This means that the new width w'$ is 75% of the original width w. Therefore, the width of the land is reduced by 25%, just like the area.

an actuary has discovered that policyholders are five times as likely to file two clams as to file four claims. if the number of claims filed has a poisson distribution, what is the variance of the number of claims filed?
The number of claims filed by the policyholders has a poisson distribution. Therefore, the variance of the number of claims filed will be about 2.5.
What is the variance?We need to use the Poisson Distribution for solving the question, which is as follows:
P(x) = (λˣ/x!) × [tex]e^(-lambda)[/tex]
where is the mean value of distribution and x is the number of events we want to calculate.
If a random variable follows a Poisson distribution, its variance is equal to its mean.
So, the mean will be λ.
Let the probability of filing four claims be p1.
Then, probability of filing two claims will be ⁵p₁
We know the sum of probabilities of different events of Poisson distribution will always be equal to 1.
So,
p₁ + ⁵p₁ = 1
p₁ = 1/6
The mean number of claims is λ, which is given by:
Now, the variance of the Poisson distribution is also λ.
So, the variance of the number of claims filed is 2.5.
Hence, the answer is variance of the number of claims filed is 2.5.
The mean number of claims is λ, which is given by:
λ = ⁴p₁ + 2⁵p₁ = 2.5

Thus,
[tex]Pr(exactly 2) = P(2) = (3C2) * 0.11^2 * 0.89^{(3-2)} = 0.0283\\Pr(exactly 1) = P(1) = (3C1) * 0.11^1 * 0.89^{(3-1)} = 0.2901\\Pr(exactly 3) = P(3) = (3C3) * 0.11^3 * 0.89^{(3-3)} = 0.001331[/tex]
Hence, the probabilities for the given event is Pr(exactly 2) = 0.0283. Pr(exactly 1) = 0.2901, and Pr(exactly 3) = 0.001331.

a spinner has three sections. the table shows the results of spinning the arrow on the spinner 80 times. what is the experimental probability of the arrow stopping over section 1? responses 128 1 over 28 720 7 over 20 713 7 over 13 45 4 over 5 section 1section 2section 3 283616
The experimental probability of the arrow stopping over section 1 is 7/13, or 0.538.
To calculate this, you need to take the number of times the arrow stopped on section 1 (45) and divide it by the total number of times the arrow was spun (80). This can be expressed as a fraction (45/80), which can be simplified to 7/13. To convert this fraction to a decimal, divide the numerator by the denominator (7/13 = 0.538).
