13 = r/12 solve for r

1 answer:

3 0

13 = r/12, first to cancel 12 and leave r alone you multiply it by 12 and it cancels and whatever you do on one side you do to the other. So you multiply 13 times 12 too.

You are then left with, 13•12 = r
Which is 156

Therefore,

r = 156

Given m ZLMN = 145°, what is m ZXMN? Show all relevant work.

myrzilka [38]

80 degrees. 145 = (4x+5) + (6x-10) = 10x-5... so 10x = 150, x = 15. LMN = 6x-10 = 6(15) - 10 = 80.

Researchers wondered if there was a difference between males and females in regard to some common annoyances. They asked a rando

Zinaida [17]

Answer:

Step-by-step explanation:

Males proportion $p_1 = \frac{163}{532} =0.3064$

Females proportion $p_2 = \frac{203}{589} =0.3447$

$H_0: p_1 = p_2\\H_a: p_1$

(one tailed test for comparison of proportions)

Test statistic = $\frac{p_1-p_2}{p(1-p)\sqrt{\frac{1}{n_1}+\frac{1}{n_2} } }$

=-1.3641

Here p= combined proportion = $\frac{163+203}{532+589} \\=0.3291$

p value = 0.0869

Since p >0.05, accept null hypothesis.

The evidence does not suggest a higher proportion of females are annoyed by this behavior
