The range is the inteval including all possible answer.

Boys' answers range from 3 to 10, whereas girls' anwers range from 5 to 9. So, the range is greater for the boys, because

$10-3=7>4=9-5$

As for the average, we have to sum all results and divide by the number of results:

$A_{boys} = \dfrac{3+6+7+7+8+8+8+8+9+10}{10} = 7.4$

$A_{girls} = \dfrac{5+6+6+6+7+7+7+8+9}{10} = 6.1$

Step-by-step explanation:

here's your solution

=> in first figure , base = 5.5, perpendicular =7.8

=> h^2 = 5.5^2 + 7.8^2

=> h^2 = 30.25 + 60.84

=>h^2 = 91.09

=> h = √91.09

=> h = 9.5

 Both figure are congruent

enc we will get a rectangle by add both 

hope it helps

If f(x)=(x-3)/x and g(x)=5x-4 what is the domain of (fOg)(x)

Leni [432]

(fog) (x) = (5x - 7) / (5x - 4)

The denominator cannot be zero so the domain is All real x except x = 4/5

A circle is dialated with a scale factor of 2/3. what is the area of the new circle if the area of the original circle is 45 squ

Sveta_85 [38]

Original Circle Area = 45

A = pi * r^2

Plug in what we know:

45 = 3.14 * r^2

Divide 3.14 to both sides:

14.3312102 = r^2

Find the square root of both sides:

r = 3.78565849

Find 2/3 of this:

2/3 * 3.78565849 = 2.52377233

So this is the radius of the newly dilated circle.

A = pi * r^2

A = 3.14 * 2.52377233^2

A = 3.14 * 6.36942677

A = 20

So the area of the newly dilated circle is 20 square inches.
