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
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).
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
Convert the quadratic equation y=−4(x−3)(2x+4) from factored form to standard form.

Answer:
10×10.70=$107 spent on cups
107-293=$186 spent on the jacket
so for the jackets 186= how many they got and much each cost.
u=186÷x
or 186=u the cost of each × x how many they got.

Answer:
m= -1/2
Step-by-step explanation:
(0,3) and (4,1)

m=(1-3)/(4-0)
m= (-2)/4
m= -1/2
A dessert recipe calls for 6 cups of cereal for every 4 cups of marshmallows. If a baker makes a 25-cup batch of treats using the proportions of the recipe, which statement is true?
A The baker uses 6 cups of cereal and 19 cups of marshmallows.
B The baker uses 10 cups of cereal and 15 cups of marshmallows.
CThe baker uses 15 cups of cereal and 10 cups of marshmallows.
DThe baker uses 19 cups of cereal and 6 cups of marshmallows.
Answer: C
Step-by-step explanation
if you say 15 and see how many times 6 can fit in it the answer is 2 and 2r so if you look at the marchmellows and see how many times 4 can fit in 10 it is 2 with 2r. they match so C is the answer

Answer:
a) 5²/4². b) 4.2²/2.8²
This is your 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?
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.

Is x - 1 factor of 7x ^ 3 - x ^ 2 - x - 5 ?
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.
