Mathematics

crimeas [40]4 years ago

Vertex form:

y = a(x - h)² + k

I have not learned this stuff yet, but by using online calculators, I can determine that the vertex form is:

Y = (x - 4)² - 19

I believe so :/

Solve<br> 3x+1=x+5<br> The solution is x
solong [7]

Answer:

x=2

Step-by-step explanation:

3x+1=x+5

Subtract x from each side to get all the variables on one side

3x-x+1=x-x+5

2x+1 = 5

Subtract 1 from each side to get all the constants on the other side

2x+1-1 = 5-1

2x= 4

Divide each side by 2

2x/2 =4/2

x =2

Information about movie ticket sales was printed in a movie magazine. in a sample of of fifty pg-rated movies, 36% had ticket sa
natima [27]

Let us say that the samples for fifty movies is 1 and samples for thirty five is 2. To solve the test statistic z, we can use the formula:

z = (p1 – p2) / sqrt [p (1 – p) (1 / n1 + 1 / n2)]

Where,

p1 = is the proportion for sample 1 = 0.36

p2 = is the proportion for sample 2 = 0.23

n1 = number of samples = 50

n2 = number of samples = 35

while p can be calculated using the formula:

p = [p1 * n1 / (n1 + n2)] + [p2 * n2 / (n1 + n2)]

p = [0.36 * 50 / (50 + 35)] + [0.23 * 35 / (50 + 35)]

p = 0.211764705 + 0.094705882

p = 0.306470587

Going back for the calculation of z:

z = (0.36 – 0.23) / sqrt [0.306 (1 – 0.306) (1 / 50 + 1 / 35)]

z = 1.279

 

Therefore the nearest answer is:

z = 1.29
