F(2) is referring to the 2 on the x-axis. You can see that the point aligning with 2 on the x-axis is also 2 on the y-axis. Therefore, f(2)=2! hope that helped
Answer:
There are <u>77</u><u> girls</u> in the class when there are 49 boys.
<span>Divide the US into groups, by state. For cluster sampling, randomly choose twenty states and use the population of those states as the sample. For stratified sampling, randomly choose 10,000 people from every state as the sample.</span>
First convert them to fractions (the answer choices are fractions):
a) 0.333... = 1/3
b) 0.555... = 5/9
Now add a and b:
1/3 (or 3/9 for a common denominator) + 5/9 = 8/9
That fraction is in simplest form, so leave it as it is.
Hope this helps!
<span>The perimeter of a Triangle is the sum of three sides ; ie assuming k,l,m be the three sides of a triangle means then k+l+m = perimeter of a triangle.
here given that a two sides lengths are 2x+ 2 and 5x-4 ;
and the perimeter length is 16x-6;
let the unknown side be k;
therefore k + 2x+2 + 5x-4 = 16x-6;
resolving k + 7x-2 = 16x-6;
Ans:-
k= 16x-6-7x+2 = 9x-4 ie the
unknown length k is 9x-4</span>
