Note that Cheryl wants to find the number of hours seventh grade boys and girls spend on homework each week.
There are multiple causes of a biased sample. Two of the most obvious ones I find are:
1. She's surveying girls, but she is trying to get data on the number of hours all seventh graders (boys and girls) spend.
2. She's surveying 50 girls from the entire school, although she is trying to get data on seventh graders only.

What is the constant term in the polynomial expression -7x2 + 32x + 240, and what does it represent?
Answer:
The constant term is 240. A constant term represents a fixed value. In other words, a term that does not change.
Step-by-step explanation:
In the polynomial expression given, the first and second terms are dependent of x, which means whatever the value x is, the terms will change. For example, if x = 2, we have -7(4) + 32(2) + 240. As you can see the constant never changes because it does not rely on a variable; it is constant.
Find the slope of the line that passes through the points (1, -2) and (9,7)
Answer:
9/8
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 7 - -2)/( 9 - 1)
= ( 7+2)/( 9-1)
= 9/8
find the slope of the line segment that contains the two points. (15, 16) and (-19, -6)

B. -2/5
C. None of the answers are correct
D. 7/15
E. -1/3
Answer:
the answer is letter A.
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=(-6)-16/(-19)-15

Two sides of a triangle measure 10 inches and 10.9 inches. The included angle between these sides is 65°. What is the approximate measure of the third side of the triangle?
Answer:
9.9inches
Step-by-step explanation:
From the attachment, the opposite side is debited as "x" while the Hypotenuse is 10.9inches, we can find the third side by using trigonometry
From trigonometry, Sin(x)= opposite/Hypotenuse
Sin(65)=X/10.9
X= Sin(65) ×10.9
X=0.9063×10.9
=9.8688
Hence the third side of the triangle is approximately 9.9inches

Step-by-step explanation:
the other guy made it a hassle for no reason
The graph shown in figure 1 is a function, and the graph shown in figure 2 is not a function
What are graphs?Graphs are the visual way of representing functions and equations
For a graph to represent a function, then the graph of the function must pass the vertical line test
Graph 1 will pass the vertical line test, while graph 2 will not
Hence, the graph shown in figure 1 is a function, and the graph shown in figure 2 is not a function

The monthly salary of Abi is less spread out than the monthly salary of Shenika. The monthly salary of Clarissa is less spread out than the monthly salary of Abi.
Answer: The monthly salary of Shenika is less spread out than the monthly salary of Clarissa.
Step-by-step explanation:
Hi. Your question isn't complete but I got something close to it online.
The monthly mean salaries and standard deviations of four college students are given below. student mean standard deviation clarissa $345 12.53 abi $598 8.99 kaila $812 15.29 shenika $208 7.67 which statement must be true?
We can see that while Shenika has a mean of $208 and a standard deviation of 7.67, Clarissa has a mean of $345 and a standard deviation of 12.53. This simply means that monthly salary of Shenika is less spread out than the monthly salary of Clarissa.
Answer:
A - The monthly salary of Shenika is less spread out than the monthly salary of Clarissa.

Answer:
Step-by-step explanation:f(h(x))= 2x -21
f(x)= x^3 - 6
h(x)=\sqrt[3]{2x-15}
WE need to find f(h(x)), use composition of functions
Plug in h(x)
f(h(x))=f(\sqrt[3]{2x-15})
Now we plug in f(x) in f(x)
f(h(x))=f(\sqrt[3]{2x-15})=(\sqrt[3]{2x-15})^3 - 6
cube and cube root will get cancelled
f(h(x))= 2x-15 -6= 2 x-21

Hurry pleaseeee taking a test Which expression is equivalent to 30°? Inverse of cosine (StartFraction StartRoot 3 EndRoot Over 2 EndFraction) Inverse of sine (StartFraction StartRoot 3 EndRoot Over 2 EndFraction) Sine (StartFraction StartRoot 3 EndRoot Over 2 EndFraction) Cosine (StartFraction StartRoot 3 EndRoot Over 2 EndFraction)
Answer:
Inverse of cosine (StartFraction StartRoot 3 EndRoot Over 2 EndFraction)
Step-by-step explanation:
According to trigonometry identity;
Cos 30° = √3/2
To get the expression equivalent to 30°, we will take the inverse of both sides as shown;
Cos^-1(cos 30°) = cos^-1(√3/2)
The arccos will cancel out the cos on the left hand side of the equation to have;
30° = cos^-1(√3/2)
Hence 30° is equivalent to inverse of cosine of √3/2 or Inverse of cosine (StartFraction StartRoot 3 EndRoot Over 2 EndFraction)
