Answer:

40 : 27

Step-by-step explanation:

$3\frac{1}{3} : 2\frac{1}{4}$

Turn into improper fractions:
$\frac{10}{3} : \frac{9}{4}$

Make them integers by multiplying them by 12:
40 : 27

Last year, 50% of MNM. Inc. employees were female. It is believed that there has been a reduction in the percentage of females i

Serhud [2]

Answer:

We conclude that there has been a significant reduction in the proportion of females.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 400

p = 50% = 0.5

Alpha, α = 0.05

Number of women, x = 118

First, we design the null and the alternate hypothesis

$H_{0}: p = 0.50\\H_A: p < 0.50$

This is a one-tailed test.

Formula:

$\hat{p} = \dfrac{x}{n} = \dfrac{118}{400} = 0.45$

$z = \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

Putting the values, we get,

$z = \displaystyle\frac{0.45-0.50}{\sqrt{\frac{0.50(1-0.50)}{400}}} = -2$

Now, we calculate the critical value.

Now, $z_{critical} \text{ at 0.05 level of significance } = -1.645$

Since the calculated z-statistic is less than the critical value, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.

Thus, there has been a significant reduction in the proportion of females.

Need points ?Answer question simple.

Tresset [83]

Answer:

45 degrees

Step-by-step explanation:

A straight line is an angle with a measure of 180°, but becasue it looks like we have two angles that create the 180° angle, therefore, it is a supplementary angle.

Knowing this

2X = 90° (right angle)

so (2X) + (2X) = 180° (supplementary angle)

Therefore, to find X you can do

2X = 90

divide by 2 on both sides (to isolate the variable we are trying to find which is X)

and you get....

X= 45 becasue 2 times 45 equals 90

answer: X=45°
