pam is 17 years old and her sister is 9. her two brothers are 11 and 7 years old. what is the mean of their ages

Answers

Answer:

11

Step-by-step explanation:

17+9+11+7 divided by 4

because the mean= sum of the terms divided by the number of terms

the sum= 17+9+11+7=44

the number of terms= 4

44 divided by 4= 11

Answer:

(17+9+11+7) / 4 mean is an average

it is equal to the sum of the elements divided by the number of elements

the sum is 44

the number of elements is 4

the mean is the average= 44/4=11

If f(1) = 8 and f(n) = -4f(n-1) + 5 then find the value of f(3).

Answers

Answer:

f(3) = 113

Step-by-step explanation:

Using the recursive rule and f(1) = 8 , then

f(2) = - 4f(1) + 5 = - 4(8) + 5 = - 32 + 5 = - 27

f(3) = - 4f(2) + 5 = - 4(- 27) + 5 = 108 + 5 = 113

Answer:

a) 5²/4². b) 4.2²/2.8²

This is your answer ☺️☺️

Answer:

a. [tex]\frac{5}{4}[/tex]

b. [tex]\frac{3}{2}[/tex] or [tex]1\frac{1}{2}[/tex]

Steps:For a.)Apply radical rule: [tex]\sqrt[n]{\frac{a}{b} } =\frac{\sqrt[n]{a}}{\sqrt[n]{b} }[/tex], assuming [tex]a\geq 0,b\geq 0[/tex]

= [tex]\frac{\sqrt{25} }{\sqrt{16} }[/tex]

[tex]\sqrt{16}=4[/tex]

[tex]\frac{\sqrt{25} }{4}[/tex]

[tex]\sqrt{25} =5[/tex]

[tex]=\frac{5}{4}[/tex]

For b.)[tex]\frac{\sqrt{18} }{\sqrt{8} }[/tex]

Apply radical rule: [tex]\frac{\sqrt{a} }{\sqrt{b} } =\sqrt{\frac{a}{b} }[/tex]

Which means[tex]\frac{\sqrt{18} }{\sqrt{8} }=\sqrt{\frac{18}{8} }[/tex]

[tex]=\sqrt{\frac{18}{8} }[/tex]

2. Cancel [tex]\frac{18}{8}[/tex]: [tex]\frac{9}{4}[/tex]

= [tex]\sqrt{\frac{9}{4} }[/tex]

Now apply the radical rule: [tex]\sqrt[n]{\frac{a}{b} } =\frac{\sqrt[n]{a} }{\sqrt[n]{b} }[/tex]  assuming [tex]a\geq 0,b\geq 0[/tex]

= [tex]\frac{\sqrt{9} }{\sqrt{4} }[/tex]

[tex]\sqrt{4}=2[/tex]

[tex]=\frac{\sqrt{9} }{2}[/tex]

[tex]\sqrt{9}=3[/tex]

The final answer for b.) should be [tex]\frac{3}{2}[/tex]

An angle measures 27.2° less than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

Step-by-step explanation:

Supplementary angles have a sum of 180 degrees.

a+a-27.2=180

2a-27.2=180

2a=207.2

a=103.6, and since b=a-27.2

b=76.4

So one angle is 103.6 degrees and the other is 76.4 degrees.

Answers

Answer:

Step-by-step explanation:

f(x)  = 7x³ - x² - x - 5

To test if (x-1) is a factor, calculate f(x) for x=1:

f(1) = 7·1³ - 1² - x - 5 = 0

Since f(1) = 0, (x-1) is a factor.
