adelina 88 [10]

The path is the hypotenuse of a right triangle with legs 30 and 120.

30² + 120² = c²

900 + 14400 = c²

15300 = c²

c=√15300 ≈123.7'

instead of walking 30+120=150 feet they save 26.3 feet by taking the shortcut

Last year, 46% of business owners gave a holiday gift to their employees. A survey of business owners indicated that 20% plan to

alisha [4.7K]

Answer:

Part a: So the number of business owners giving holiday gift to their employees from survey is 12.

Part b: p-value is 0.00003

Part c: value of p is less that a we reject the null hypothesis.

Step-by-step explanation:

Part a

number of business owners=20% x n

number of business owners= 0.2x 60

number of business owners=12

Part b

H0: p=0.46

H1: p<0.46

Here

n=60, $\hat{p}$ =0.2, p=0.46

So test statistics is given as

$z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}\\z=\frac{0.20-0.46}{\sqrt{\frac{0.46(1-0.46)}{60}}}\\z=\frac{-0.26}{0.064}\\z=-4.04$

p-value is P(z<-4.04)= 0.00003

Part c

As value of p is less that a we reject the null hypothesis.

5 and -7 are the solutions to (x-5) (x+7) =12

konstantin123 [22]

Answer: No

Step-by-step explanation:

$(x-5)(x+7)=12$

Replace x for 5 and -7 separately.

$(5-5)(5+7)=12\\0(12)=12\\0=12$

$(-7-5)(-7+7)=12\\-12(0)=12\\0=12$
