Reports have shown that 3% of all births produce twins. Data from one hospital Shows that 7 sets of twins are were born to 445 young mothers. Is this rate the same for young mothers?
Please type the responses.
A. Write the appropriate hypotheses
B. Check the necessary assumptions
C. Perform the mechanics of the test. What is the p-value?
D. Using a significance level of 0.05, what do you conclude? Be sure to provide context
E. If you changed the significance level to 0.01 , would that impart your answer for D? Why or why not?

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

b, i believe, but not sure.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
