<span>Since there is no files attached to see the shape of the distribution, let us just have it this way:
The statement, "Because the two distributions displayed below have similar shapes, they have the same standard deviation." is false. This is false because distributions having the same mean and standard deviation can have very different shape of distribution. </span>
I believe the answer is 81x^4-16x^2 difference of squares
Answer:
There are 600 students in this school.
Step-by-step explanation:
Let p represent the total population of the school.
Then (1/3)p represents the number of students who like math. Subtracting this (1/3)p from p gives an expression representing those who do not like math:
p - (1/3)p = (2/3)p
400 students do not like math, so (2/3)p = 400.
Solve this for p by multiplying both sides by (3/2):
(3/2)(2/3)p = (3/2)(400), which simplifies to p = 600.

Answer:
x = 1/9.
Explanation:
-4(2x - 5) – (7 – 3x) = 4(x + 3)
-8x + 20 - 7 + 3x = 4x + 12
-8x + 3x - 4x = 12 + 7 - 20
-9x = -1
x = 1/9.
Hi there,
There are 16 members in a math club such as 2 girls and 14 boys in a math club.
The ratio would be:
1:7
Divide both terms by 2.
2 ÷ 2 = 1
14 ÷ 2 = 7
Therefore:
2 : 14 = 1 : 7
