Answer:
18 dimes, 12 quarters
Step-by-step explanation:
We are to solve the system of linear equations for D and Q, where D is the number of dimes and Q is the number of quarters.
Each dime is worth $0.10 and each quarter $0.25. Thus, D dimes are worth ($0.25/dime)D and Q quarters ($0.25/quarter)Q.
The sum of D and Q comes out to 30 coins, a mixture of dimes and quarters: D + Q = 30, so Q = 30 - D.
Now let's solve this equation: ($0.10/dime)D + ($0.25/quarter)Q = $4.80.
Substitute 30 - D for Q:
($0.10/dime)D + ($0.25/quarter)(30 - D) = $4.80
This is now entirely in D (no Q shows up). Performing the indicated multiplication, we get 0.10D + 0.25(30) - 0.25D = 4.80
Combining like terms: 0.10D - 0.25D = -0.15D, and -7.5 + 4.80 = -2.7
Thus, -0.15D = -2.70, and so D = 2.70/0.15 = 18 (There are 18 dimes.)
Since Q = 30 - D, and D - 18, Q = 30 - 18 = 12 (There are 12 quarters)

Two functions are given below: f(x) and h(x). State the axis of symmetry for each function and explain how to find it.
f(x) h(x)
f(x) = −4(x − 8)^2 + 3 graph of negative 1 times the quantity of x minus 3 squared, plus 2
Q4:
The functions f(x) = (x + 1)^2 − 2 and g(x) = −(x − 2)^2 + 1 have been rewritten using the completing-the-square method. Apply your knowledge of functions in vertex form to determine if the vertex for each function is a minimum or a maximum and explain your reasoning.

SAME SCENARIO - DIFFERENT QUESTION
Eliza intends to buy a new vehicle. She wishes to estimate the average fuel efficiency (in miles per gallon) of all family sized SUVs currently available on the market. Eliza selects a random sample of 15 family sized SUVs on the market and looks up their fuel efficiency on a trusted website. The results of the random sample are shown below:
27, 28, 30, 28, 28, 31, 29, 33, 28, 28, 31, 33, 41, 41, 25
If Eliza were to take another random sample of 15 SUVs from the same population, would she be likely to get the exact same value for the mean?
Question 2 options:
Yes, it is likely that Eliza will get the exact same value for the sample mean
No, it is not likely that Eliza will get the exact same value for the sample mean
There is not enough information to answer this question.
Answer:
No, it is not likely that Eliza will get the exact same value for the sample mean

You are analyzing a scatter plot that has a negative correlation. What is true of the of the x and y values?
Answer:
As x increases, y decreases
Correlations on a scatter plot can either be positive or negative. When it has a negative correlation, it means the x values increases as the y values decreases.
There are basically two types of correlation on the scatter plot
Positive correlationNegative correlationA positive correlation is such that as x increases, y also increases.
However, a negative correlation is such that as x increases, y decreases.
Hence, we can conclude that the x and y values of a scatter plot with negative correlation are in opposite direction.
See attachment for a scatter plot with negative correlation.

2) you need to make all the fractions have the same numerator so you will multiply both the firs and third fraction by 3÷3 ( which is 1 and will not affect the value but will make the numerator of the fractions equal) and the fractions between them is the second fraction and it's denominator is x and there is 5 fractions between the two numbers so there are 5 possible values of x
