Answer:
D. 3
Step-by-step explanation:
The sides with lengths 25 and 5 are corresponding, so their ratio is 25/5 = 5/1
The sides with lengths 18 - x and x are also in a 5 to 1 ratio.
5/1 = (18 - x)/x
5x = 18 - x
6x = 18
x = 3

Answer:
the sampling distribution of proportions
Step-by-step explanation:
A sample is a small group of observations which is a subset of a larger population containing the entire set of observations. The proportion of success or measure of a certain statistic from the sample, (in the scenario above, the proportion of obese observations on our sample) gives us the sample proportion. Repeated measurement of the sample proportion of this sample whose size is large enough (usually greater Than 30) in other to obtain a range of different proportions for the sample is called the sampling distribution of proportion. Hence, creating a visual plot such as a dot plot of these repeated measurement of the proportion of obese observations gives the sampling distribution of proportions
If 45=15h then h must be 3
Let x be the base of the triangle, and
2x + 4 be the height.
One of the ways in solving for the area of a triangle is to half the product of its height (h) and base (b). Mathematically,
A = bh / 2
Substituting the expression for b and h and the given condition for the area,
<em>(x)(2x + 4) / 2 ≤ 168</em>
