Answer:

7(60+3)

Step-by-step explanation:

The distributive property is a(b+c) = ab+ac

7 x 63 = (7x60) + (7x3) = 7(60+3)

So in distributive form it would be 7(60+3)

More likely -You are more likely to commit a Type I error

According to statement

we have to find the type 1 error by using the significant levels.

we are commit a MORE LIKELY to find the error by rejecting a true null hypothesis using the 0.05 level of significance than using the 0.01 level of significance.

So, More likely -You are more likely to commit a Type I error

Lisa [10]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's find the Radius ~

$\qquad \sf \dashrightarrow \: area = \frac{ \theta}{360} \times \pi {r}^{2}$

$\qquad \sf \dashrightarrow \: 80= \frac{ 72}{360} \times \pi {r}^{2}$

$\qquad \sf \dashrightarrow \: {r}^{2} = \frac{80 \times 360}{72 \times \pi}$

$\qquad \sf \dashrightarrow \: {r}^{2} = \frac{80 \times 5}{ \pi}$

$\qquad \sf \dashrightarrow \: {r}^{} = \sqrt\frac{400}{ \pi}$

$\qquad \sf \dashrightarrow \:r = \frac{20}{ \sqrt{\pi} }$

$\qquad \sf \dashrightarrow \:r \approx 11.28 \: ft$

I hope you understood the whole procedure, let me know if you have doubts ~
