Answer:
The answer is "99.82% and 86.99%".
Step-by-step explanation:
In point a:
[tex]=P(X < 45)\\\\= P(Z < \frac{45-29.09}{5.46}) \\\\=P(Z < 2.9139)\\\\=0.9982\\\\=99.82\%[/tex]
In point b:
[tex]=P(X >17)\\\\= P(Z > \frac{17-22.37}{4.77}) \\\\=P(Z > -1.1258)\\\\=0.8699\\\\=86.99\% \\\\[/tex]
Rewrite 12/5
as a mixed number.
Answer:2 2/5
Step-by-step explanation:
answer
2 2/5
Explanation
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.
les diviseurs de 25 sont des diviseurs de 15. Vrai ou faux?
Answer:
c'est faux parce que 3 n'est pas un diviseur de 25 et c'est pour 15 so not all divisor of 25 sommes diviseur de 15
The area of a round table in Kim's living room is 201 square inches. What is the circumference of the round table in inches?
Use 3.14 for π and round to the nearest hundredth of an inch if necessary
A. 8
B. 25.12
C. 50.24
D.100.48
Answer:
A. 8
Step-by-step explanation:
You must take the area and divide it by [tex]\pi[/tex]
201 divided by 3.14
Then take the number you got
201 divided by 3.14 = 64.0127388535
Then find the square root of that number
[tex]\sqrt 64.0127388535[/tex] = 8.000796139
Simplify & you get 8.
Triangle GHK has an area of m square units. If the height of the triangle is increased to five times the current height, and the length of the base increased to four times the current length, what will be the area of the larger triangle?
Answer:
20m square units
Step-by-step explanation:
The area of a traingle = bh/2............... Equation 1
Where b = lenght of the base, h = heigt of the triangle.
From the question,
The area of triangle GHK = m square units., let the base and the heigth of the triangle be x and y respectively
Therefore,
b = x, h = y
Substitute these values into equation 1
m = xy/2................... Equation 2
If the height of the triangle increase to five times the current height, and the length of the base increase to four times the current length.
Therefore,
height of the larger triangle = 5y, base of the larger triangle = 4x
Substitute these values into equation 1
Area of the larger triangle = (5y×4x)/2
Area of the larger triangle = 20xy/2................. Equation 3
Substitute equation 2 into equation 3
Area of the new triangle = 20m square units.

Given a polynomial f(x), if (x − 3) is a factor, what else must be true?
f(3) = 0
f(−3) = 0
f(0) = 3
f(0) = −3
Answer:
A
Step-by-step explanation:
Recall that according to the Polynomial Remainder Theorem, if we divide a polynomial f(x) by a binomial in the form (x - a), then the remainder will be f(a).
And by the Factor Theorem, in order for a binomial (x - a) to be a factor of a polynomial f(x), the remainder must be 0. In other words, f(a) = 0.
We are given a polynomial f(x) and that (x - 3) is a factor.
Therefore, a = 3.
And since it is a factor, by the Factor Theorem, the remainder must be 0.
Therefore:
[tex]f(3)=0[/tex]
The answer is A.
Answer:f(−3) = 0

Peter says that 3/4 of a pizza is always the same as 6/8 of a pizza. Nadia says that while they are equivalent fractions, 3/4 and 6/8 of a pizza could represent different amounts. Use a counter example to explain who is correct. Please I need your help. If you help you are nice and god will protect you forever.
Answer:
Nadia
Step-by-step explanation:
6/8 is 3/4 and both are 75% of a pizza but, the eighths of a pizza is a smaller slice of pizza.
4/4 is four slices of pizza
8/8 is eight slices of pizza
They are different amounts.

Which color's observed frequency is closest to its expected frequency?
red
blue
green
O yellow
Answer:
Blue
Step-by-step explanation:
Expected frequency is:
red 10/40 = 1/4 = 0.25 = 25%
blue 10/40 = 1/4 = 0.25 = 25%
yellow 10/40 = 1/4 = 0.25 = 25%
green 10/40 = 1/4 = 0.25 = 25%
Observed Frequency is:
red 1/7 = 0.14 = 14%
blue 2/7 = 0.28 = 28% √
yellow 4/7 = 0.57 = 57%
green 0/7 = 0.00 = 0%

ANSWER QUICK
A backpack is on sale for 15% off the original price of $39.99. What is the sale price?
Answer:
33.99
Step-by-step explanation:
multiply the original by 100-the sale percentage
(100-15 = 85
.85x39.99
Answer:
$33.99
Step-by-step explanation:
We are given that we have 15%.
What this means is that we subtract 15% from 100%.
Doing that we get 1.00 - 0.15 = 0.85
Therefore the price equals $39.99 * 0.85
The final price is $33.99

Step-by-step explanation:
If the student is a domain/inout and the hair color is the range/output how is these two set of relation not a function?
Answer:
A function is a relation that maps inputs from a set called the domain, into outputs from a set called the range.
Such that each input can be mapped into only one output.
So for example, if we have a relation that maps the input 2 into two different values:
f(2) = 4
f(2) = 8
Then this is not a function.
In the case of the problem, we have a student as the input, and the hair color as the output.
So we will have something like:
f(student) = blond
And if this student decides to change his/her hair color to red?
Then the function becomes:
f(student) = red
So for the same input, we had two different outputs, which means that this is not a function.
We also could have the case where a given student has two colors (Californian for example)
Where again, we would see two different outputs for one single input.
