Answer:
40 : 27
Step-by-step explanation:

Turn into improper fractions:

Make them integers by multiplying them by 12:
40 : 27
Well, it's simple. There are 3 zeros in 1,000. Just add 3 zeros. You get 123679882652000
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
This is a one-tailed test.
Formula:
Putting the values, we get,
Now, we calculate the critical value.
Now, 
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.
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°
