Answer:
the z-score is within 3
Step-by-step explanation:
first you got to take the standard deviation and add it to the mean since 375 is greater than 250. so the equastion would be
250+50=300+50=350+50=40
so the z-score for the value of 375 is within 3
Answer: 2
Step-by-step explanation:
z=\frac{x-\mu}{\sigma}
z=
σ
x−μ
z-score formula
z=\frac{300-250}{25}
z=
25
300−250
Plug in values
z=\frac{50}{25}
z=
25
50
Subtract
z=2
z=2
Divide
\text{They scored 2 standard deviations above the mean.}
They scored 2 standard deviations above the mean.

Answer:
C. ⅓ × (8 + 7) + 12
Step-by-step explanation:
Let's translate each statement given to numerals and symbols first:
Twelve => 12
One-third => ⅓
Sum of 8 and 7 => (8 + 7)
Representing this statement altogether will be:
⅓ of (8 + 7) = ⅓ × (8 + 7)
If 13 is added, we would get:
⅓ × (8 + 7) + 12

What are the measures of ∠1 and ∠2?
Answer:
Angle 1 = 102
Angle 2 = 40.9
Step-by-step explanation:
[tex]1)\ 180 - 121.8 = 58.2[/tex]
[tex]2)\ angle\ 2 = 58.2 - 17.3 = 40.9[/tex]
[tex]3)\ angle\ 1 = 180 - 40.9 - 37.1 = 102[/tex]
Answer:
m∠1 = 67.4° m∠2 = 104.5°
Step-by-step explanation:
17.3 + m∠2 = 121.8
m∠2 = 104.5°
m∠1 + 37.1 = m∠2 = 104.5
m∠1 = 67.4°

What is the volume of hemisphere with a radius of 8 ft rounded to the nearest tenth of cubic foot
Answer:
1072.3[tex]ft^{3}[/tex]
Step-by-step explanation:
A hemisphere is half of a sphere, so the volume V of the hemisphere is the volume of the sphere divided by 2.
V = (2/3)*[tex]\pi[/tex][tex]r^{3}[/tex]
= (2/3)*[tex]\pi[/tex][tex](8ft)^{3}[/tex]
= (2/3)*[tex]\pi[/tex]*512[tex]ft^{3}[/tex]
= 1072.3[tex]ft^{3}[/tex]

tan 30 = opp./adj
tan30 = x / 12
x = 12 tan30 ≅6.93
Mrs. McClure's famous peanut butter cookies call for 1 cup of peanut butter for every 1 2 of a cup of oil. Today, she wants to make a huge batch with 1 cup of oil. How much peanut butter should she use?
Answer:
Amount of butter need for 1 cup of oil = 2 cup of butter
Step-by-step explanation:
Given:
Amount of butter need for 1/2 cup of oil = 1 cup
Find:
Amount of butter need for 1 cup of oil
Computation:
Amount of butter need for 1/2 cup of oil = 1 cup
1 cup butter = 1/2 cup oil
So,
Amount of butter need for 1 cup of oil = 1 / [1/2]
Amount of butter need for 1 cup of oil = 1 / [0.5]
Amount of butter need for 1 cup of oil = 2 cup of butter
= 1 cubic ft

the table describes some of the solutions of the inequality 3m>21. Which graph best describes the solutions of 3m>21?
Answer:
Option 3
Step-by-step explanation:
Given inequality is,
[tex]3m\geq 21[/tex]
To find the solutions of the given inequality solve this inequality first.
[tex]\frac{3m}{3}\geq \frac{21}{3}[/tex]
[tex]m\geq 7[/tex]
This inequality will be represented by an arrow starting from 7 and directing towards infinity.
Since, inequality is having a sign notation of greater than equal to, arrow will start with a dark circle located at 7.
Therefore, Option 3 (from the top) will be the answer.

Choose a number sentence is that illustrates distribute property of multiplication over addition 2×7+8 = 2+7×2+8
Answer:
[tex](b)\ 2 * (7 + 8) = (2 * 7) + (2 * 8)[/tex]
Step-by-step explanation:
Given
[tex](a)\ 2 * (7 + 8) = (2 + 7) * (2 + 8)[/tex]
[tex](b)\ 2 * (7 + 8) = (2 * 7) + (2 * 8)[/tex]
[tex](c)\ 2 * (7 + 8) = (2 * 7) + 8[/tex]
Required
Which illustrates distributive property of multiplication over addition
The property states that:
[tex]a(b + c) = a * b + a * c[/tex]
By comparison
[tex]a = 2\ b = 7\ c = 8[/tex]
So, we have"
[tex]2(7 + 8) = 2 * 7 + 2 * 8[/tex]
[tex]2(7 + 8) = (2 * 7) + (2 * 8)[/tex]
