Answer:
$2.35 for one video
Step-by-step explanation:
You set up two equations:
$7.50= p + 2v
$12.20= p + 4v
You then set both equal to p
p=-4v+12.20 and p=-2v+7.50
So you can set them equal to each other and solve for v (the cost of one video)
v= $2.35

Jason bought a case of Macaroni and Cheese last week for $12.56. This week he bought the same size case for $16.98. What was the percent increase? Round to the nearest percent.
a
26%
b
42%
c
4.42%
d
35%
Answers
Answer:
A
Step-by-step explanation:
[tex] \frac{16.98 - 12.56}{16.98} \times 100 = 26[/tex]
Answer:
35.191083%
Step-by-step explanation:
12.56/100=0.1256 (1%)
That's one percent of 12.56. How much by 0.1256 (1% of 12.56) is 16.98 (rised price)?
I used a two-step equation to get the answer
x*0.1256 = 16.98 /0.1256 /0.1256Divide both sides to get
x = 135.191083Now just subtract 100 because that was the old value
135.191083 - 100 = 35.191083and you get 35.191083. Therefore, the answer is D.
A consumer report claims that more than 10% of the cars from a car manufacture experience engine failures before reaching a mileage of 150,000 miles. A sample of 65 cars is investigated and 9 of the cars had engine failure before 150,00 miles. Conduct a hypothesis test to test the claim with a significance level of 0.10.
Answers
Answer:
We will fail to reject the null hypothesis and conclude that there is no sufficient evidence to suggest that more than 10% of the cars from a car manufacture experience engine failures before reaching a mileage of 150,000 miles
Step-by-step explanation:
We are given;
Population proportion; p_o = 10% = 0.1
Sample proportion; p = 9/65 = 0.1385
Z-score formula for this is;
z = (p - p_o)/√(p_o(1 - p_o)/n)
z = (0.1385 - 0.1)/√(0.1(1 - 0.1)/65)
z = 0.0385/0.0372
z = 1.03
From online z-score calculator, we have; p - value = 0.1504
Our p - value is greater than the significance level of 0.1.
Thus,we will fail to reject the null hypothesis and conclude that there is no sufficient evidence to suggest that more than 10% of the cars from a car manufacture experience engine failures before reaching a mileage of 150,000 miles

Natalie wants to buy 5 feet of ribbon for her scrap book supplies. The store only sells the ribbon in inches. How much ribbon does Natalie need in inches?
Answers
Answer:
She would need 60 inches or ribbon.
Step-by-step explanation:
there are 12 inches in a foot, if she needs 5 feet then you would multiply 12 and 5
12*5 = 60
Well, we know that there is 12 inches in every foot, so if you have 5 feet, you would just have to multiply 12 x 5.
The answer is 60 inches of ribbon.

If the base angles of an isosceles triangle each measure 37 degrees, then the
vertex angle measures 106 degrees. *
True
False
pls help
Answers
Answer:
The statement is true.
Step-by-step explanation:
The statement is true.
Reason:
The sum of all angles of triangle is equal to 180°
If base angles are 37° and vertex angle is 106° there sum must be equal to 180°
Checking: 37+37+106 = 180°
So, the statement If the base angles of an isosceles triangle each measure 37 degrees, then the vertex angle measures 106 degrees is true.

Step-by-step explanation:
Identify the values of each variable in the formula. Remember to express the percent as a decimal.
APrt=?=$8,500=0.0298=12 years
For compounding continuously, use the formula A=Pert.
Substitute the values into the formula and compute the amount to find
AA=8,500e0.0298⋅12=$12,154.10.

The solution of the system of linear inequalities is All values that satisfy y<1/3-3 are solutions. (option 2)
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given is a graph of inequalities, y < 1/3x-1 and y < 1/3-3
The solution of the inequality A is the shaded area below the solid blue line and the solution of the inequality B is the shaded area below the solid red line,
That means all the solutions of inequality B will satisfy the inequality A also.
Hence, The solution of the system of linear inequalities is All values that satisfy y<1/3-3 are solutions. (option 2)
