Answer: a
Step-by-step explanation:
If a cube is rolled by 30 times then 5 times 2s will make the question the model.
What is probability?Probability is the occurrence of any event or how likely an event can happen.
Mathematically probability = the number of desired outputs by the number of the possible outcomes.
In the number cube, there are six faces above each of them written one to six later.
The probability of getting 2 at once time will be 1/6 since the number of desired output is only one and possible outcomes are six.
Mathematically(Theoretically) if we roll the cube 30 times then the number of 2s will be 1/6 × 30 = 5 times.
If experimentally if we roll dice and the number of 2s came 5 times then our question will become a model.
So by 5 times, 2s will make the question model.

Someone pls help. Write the equation in standard form
Answer:
Step-by-step explanation:
Since, zeros of the relation are 5, 6 and y-intercept is (0, 30).
Therefore, equation of the quadratic relation will be in the form of,
y = a(x - 5)(x - 6)
For (0, 30),
30 = a(0 - 5)(0 - 6)
30 = 30a
a = 1
Therefore, equation will be,
y = (x - 5)(x - 6)
y = x² - 11x + 30
y = x²- 2(5.5)x + (5.5)² - (5.5)² + 30
y = (x - 5.5)²+ 30 - 30.25
y = (x - 5.5)² - 0.25 [Standard form}
b). Vertex → (-4, -7) and passes through a point (-2, 1)
Vertex form or standard equation of the quadratic relation is,
y = a(x - h)² + k
Here, (h, k) is the vertex
Therefore, equation will be,
y = a(x + 4)² - 7
Since, (-2, 1) lies on this relation
1 = a(-2 + 4)² - 7
a(2)²- 7 = 1
4a = 8
a = 2
Equation will be,
y = 2(x + 4)²- 7

I bought four bags of cotton candy for $1.50 each and two soft drinks for 90 cents each. What was my change from a ten dollar bill
Answer:
Your change is $2.20
Step-by-step explanation:
4 x $1.50 = $6
2 x $.90 = $1.80
$6 + $1.80 = $7.80
$10 - $7.80 = $2.20
So it's $2.20. Have a nice day :D
Answer:
$2.20
Step-by-step explanation:
4 bags of cotton candy
$1.50 x 4 = $6.00
2 soft drinks
$0.90 x 2 = $1.80
$6.00 + $1.80 = $7.80
$10.00 - $7.80 = $2.20
Steph has 7 gallons of water josh has 26 quarts of water how many more cups of water does Steph have than josh
Answer:
8 CUPS
Step-by-step explanation:
We have to convert gallons and quarts to cups and subtract the values
1 gallon = 16 cups
7 gallons = 7 x 16 = 112 cups
1 quart = 4 cups
26 quarts = 26 x 4 = 104 cups
112 - 104 = 8 cups

Answer:
(0, -10), (2, 0), (-2, -50)
Step-by-step explanation:
Plug in numbers for the x and solve for it
I will start with 0
y = 5(0 - 1)^2 - 5
y = 5(-1) - 5
y = -5 - 5
y = -10
2
y = 5(2 - 1)^2 - 5
y = 5(1) - 5
y = 5 - 5
y = 0
-2
y = 5(-2 - 1)^2 - 5
y = 5(-9) -5
y = -45 - 5
y = -50

Part B Isabella's mother sells the peas and gets $3 for each square foot. So, multiply your answer from Part A by 3 to calculate how much money Isabella's mother made.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the solution to part A (or part A itself) is not given. To solve this, I will assume a value to the supposes solution to part A.
From the question:
1 square foot is sold at $3.
This implies that:
p square foot will be sold at $3p.
So, total sales can be calculated using:
[tex]Total = 3p[/tex]
Now assume that p is 10 square feet (from part A).
The total will be:
[tex]Total = 3*10[/tex]
[tex]Total = \$30[/tex]
