Which value could go in the blank cell so that the percentage of only children that
have no pets is 37.5%?
A. 63
B. 82
C. 175
D. 205
Answers
Answer:
maybe B
I am not to my answer
The solution is Option A.
The number of only children with no pets is given by the equation A = 63 and the percentage would be P = 37.5 %
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of only children with no pets be A
Now , the equation will be
The number of siblings with pets = 82
The number of siblings with no pets = 141
The number of only child with pets = 105
Now , let A = 63
So , the total number of children = 105 + 63 = 168
The percentage given is P = 37.5 %
So , the percentage of children with no pets P = ( number of only children with no pets / total number of children ) x 100
Substituting the values in the equation , we get
Percentage of children with no pets P = ( 63 / 168 ) x 100
Percentage of children with no pets P = 0.375 x 100
Percentage of children with no pets P = 37.5 %
Therefore , the value of A is 63
Hence , the number of children with no pets i 63

Alex rents a car for one day. The charge is $18 plus $0.12 per mile. Alex wants to spend exactly $30. Write an equation to represent the situation.
A) 30 - 0.12 = 18x
B) 18 + 0.12x = 30
C) 18 - 0.12x = 30
D) 18x + 0.12 = 30
please help
Answers
Answer:
B)
Step-by-step explanation:
Because it says that Alex wants to spend exactly $30 so you want to have 30 as the total ( = 30 )
and it says 18 plus, you only add 18 one time ( 18 + )
and then it says 0.12 per mile, so you need to do something times 0.12 + 18 and get exactly 30. so you do ( 0.12x ) in this case we're not solving it we're just doing the equation so it's just 0.12x instead of a specific number
Put it all together and you get 18 + 0.12x = 30

Keith sampled 10 private universities in Colorado and recorded the tuition cost. Keith wants to test the hypothesis that the tuition of these 10 universities is more expensive than the national average tuition, which is $29,056 with a population standard deviation of $3,339.
z equals fraction numerator x with bar on top minus mu over denominator begin display style fraction numerator sigma over denominator square root of n end fraction end style end fraction
If the sample mean is $31,650, what is the z-score? Answers are rounded to the hundredths place.
Answers
Answer: The z-score = 2.46
Step-by-step explanation:
Given: sample size : n= 10
Population mean : [tex]\mu= 29056[/tex]
population standard deviation : [tex]\sigma= 3339[/tex]
Sample mean : [tex]\overline{x} = 31650[/tex]
Formula to calculate z :
[tex]z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}[/tex]
Substitute all values, we get
[tex]z=\dfrac{31650-29056}{\dfrac{3339}{\sqrt{10}}}\\\\=\dfrac{2594}{\dfrac{3339}{3.16227766}}\\\\=\dfrac{2594}{3339}\times3.16227766\approx2.46[/tex]
Hence, the z-score = 2.46

120° and 60°
Step-by-step explanation:
The sum of the exterior angle of a polygon is 360°, then
exterior angle = 360° ÷ 3 = 120°
The exterior and interior angle sum to 180°, then
interior angle = 180° - 120° = 60°

Given f(x) = 6x^4, find f^-1(x). Then state whether f^-1 (x) is a function.
A. Y=+or-(x/6)^4; f^-1(x) is not a function
B. Y= +or- (x/6)^4 ; f^-1(x) is a function
C. Y= +or- (x/6)^1/4 ; f^-1(x) is a function
D. Y= +or- (x/6)^1/4 ; f^-1(x) is not a function
Answers
Answer:
D. Y= +or- (x/6)^1/4 ; f^-1(x) is not a function
Step-by-step explanation:
A function g is the inverse of function f if for y=f(x), x=g(y).
y = 6x^4
Replace x with y:
x = 6y^4
Solve for y:
+or- x^1/4 = 6y
+or- (x/6)^1/4 = y
For each x there are 2 values of y: negative and positive. So, it is not a function.
