Graph C. The equation of the line is y=2x+5. 5 is the y-intercept so the line has to go through that point.
R2+15r+36=0 the answer is r=6
She will have 6 braces left over since 8x8=64 and 70-64=6

Answer – C. the sample size 16 is too small
If we toss a coin 16 times in order to test the hypothesis
H0: p = 0.5 that the coin is balanced, we can't use the z-test for a proportion
in the situations because the sample size 16 is too small. The z-test is best
used when the sample size is greater than 30; when the sample size is less than
30, t-test is more appropriate.
