Answer:
d) 1
Step-by-step explanation:
The variance of standard normal distribution is simply put as 1.
If you take it a bit further, even though not asked, the mean of a standard normal distribution is 0.
Therefore, the conclusion is that, the variance of a standard normal distribution is 1, while the mean of the same standard normal distribution is 0

A plumber charges $35 to make a house call, plus $25 an hour for labor. The following equation represents f(x), the total cost of a visit for x hours: f(x) = 25x+35. What is the independent variable? * 10 points Number of hours worked Amount of money paid Price of labor House call charge
The correct answer is A. Number of hours worked
Explanation:
In the equation presented, the number of hours worked is the only factor that varies, it is expected the plumber has to work a different number of hours depending on each situation and this affects the final cost as the number of hours is multiplied by $25 (cost of one hour). On the other hand, factors such as the house call charge or the price of an hour for labor are fixed and do not change.
Moreover, in equations, the factor that changes and can affect others is known as the independent variable. This means the number of hours can be classified as the independent variable because this is not fixed and affect other variables including the total cost.

Answer:
c. The square root of 12 is between 4 & 5.
Step-by-step explanation:
a. The square root of 112 is between 10 & 11
i. Find the squares of 10 & 11
10² = 100
11² = 121
Because 100 < 112 < 121, we know the square root of 112 is between 10 & 11
b. The square root of 180 is between 13 & 14
i. Find the squares of 13 & 14
13² = 169
14² = 196
Because 169 < 180 < 196, we know that the square root of 180 is between 13 & 14
c. The square root of 12 is between 4 & 5.
i. Find the squares of 4 & 5
4² = 16
5² = 25
Because 12 < 16 & 25, we know that the square root of 12 is not between 4 & 5.
d. The square root of 5 is between 2 & 3.
i. Find the squares of 2 & 3
2² = 4
3² = 9
Because 4 < 5 < 9, we know that the square root of 5 is between 2 & 3.
Sara bought a 24-ounce can of tomato sauce for $6. What is the unit price per ounce? *
Answer: 25 cents
Step-by-step explanation:
24 ounces = 6 dollars. Divide 24 by itself to get 1 ounce. Then, divide 6 by 24 to get 25 cents.
The unit price per ounce is 25 cents.
It is required to find the unit price per ounce.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
We know that,
24 ounces = 6 dollars.
Divide 24 by itself to get 1 ounce.
1 ounces = 6/24 dollars.
1 ounces = 1/4 dollars.
1 ounces = 1/4*100 cents
1 ounces =25 cents.
Therefore, the unit price per ounce is 25 cents.

Answer:
3x+8-2(1-x)=1
First, multiply 2x1 and 2x-x
3x+8-2+2x=1
Then rearrange the terms
3x+2x+8-2=1
Then combine like terms
5x+6=1
Then subtract 6 on both sides
5x=-5
Then divide 5 on both sides
x=-1

2. Three numbers whose product is 64 are 2, 4,
and 8 because 2 x 4 x 8 = 64.
a. Find three numbers whose product is 2.4.
b. Find another set of three numbers whose
product is 2.4.
c. Find three numbers whose sum is 2.4.
d. Find another set of three numbers whose
sum is 2.4.
Answer:
A) 0.8 X 3 X 1 = 2.4
B) 0.3 X 2 X 4 = 2.4
C) 0.4 + 1.5 +0.5 = 2.4
D) 2 + 0.3 + 0.1 = 2.4
Step-by-step explanation:
A) To get three numbers whose product is 2.4, we will have to find out by multiplying three different decimal numbers to see if we can get 2.4. In other words, we are looking for factors of 2.4.
We can start by dividing 2.4 by three.
This will give 0.8 ( which is one of the numbers)
Recall that 1 is also a number and any number multiplied by 1 is itself. We can take one to be our third number.
Our three numbers are 0.8 X 3 X 1 = 2.4
B) To get another set of numbers, we can simply choose to divide 2.4 by 4.
2.4 / 2 = 0.6.
we can also divide 0.6 into 2.
0.6 / 2 = 0.3
Our other three numbers can be 0.3 X 2 X 4 = 2.4
C) Three numbers which can sum up to 2.4 are
0.4 + 1.5 +0.5 = 2.4
D) To get another set of numbers, we can simply break 2.4 up into other simpler numbers.
2 + 0.3 + 0.1 = 2.4

A floor 10m by 40m is covered by square tiles 20cm. How many tiles are needed to cover the floor?
Answer:
10,000
Step-by-step explanation:
We can find the area of the floor in cm^2 and divide by the are of 1 tile in cm^2.
1 m = 100 cm
10 m = 1000 cm
40 m = 4000 cm
area of floor = LW = 1000 cm * 4000 cm = 4,000,000 cm^2
area of tile = s^2 = (20 cm)^2 = 400 cm^2
number of tiles = 4,000,000/400 = 10,000
Answer: 10,000 tiles
Write these numbers in order of size. Start with the smallest number. 3/7,41%, 0.45,
Question: Write these numbers in order of size. Start with the smallest number. 3/7,41%, 0.45.
This is EASY! Here's your answer, hope it helps:
0.45, 3/7, 41%
Step-by-step explanation:
0.45 is first because it is the smallest percentile what i mean by this is anything with a point or anything with the number 0 comes first.... IF THE NUMBER 0 IS THE FIRST NUMBER OF THE NUMBER CHARACTERISTIC!
Why this is true? Well depending on your grade if you know your numbers... 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22... and so on. (You should know this if you are being asked this question). The rest are as simple as this.
3/7 comes next (the second highest number). How i know this is by reviewing the number chart listed above coming as the third highest number starting from 1 (1, 2, 3)
Lastly 41% is the last number/percentile. Which in conclusion on the number chart, YES! you cant find it because i stoped at number 22 and for your correct answer the number 41 is 19 numbers away from 22 which gives me the answer that the correctness to this question and format would be that 41% is the last number to this question.
If you have any more question over why i found this to be the correct answer please ask i will be glad to assist you. Thank you and have a great day!
Answer:
41%, 3/7, 0.45
Step-by-step explanation:
41% = 0.41
3/7 = ~0.43
0.45 =...0.45

A child randomly selects a jellybean from a jar of jellybeans. The probability that the child selects a grape jellybean is 7/22, and the probability that he selects a grape jellybean or a cherry jellybean is 13/23. What is the probability that the child selects a cherry jellybean?
Answer:
6/23
Step-by-step explanation:
Since there are 7 grapes and 13 grapes AND cherry. 13-7 is 6. So the cherry jellybeans will be 6.
The midpoint of AB is M(-5, 4). If the coordinates of A are (-4, 2), what are the coordinates of B?
Answer:
(-6, 6)
Step-by-step explanation:
Let the coordinates of point B be (x, y)
Since, M is the midpoint of AB.
Therefore, by mid-point formula:
[tex] - 5 = \frac{ - 4 + x}{2} \\ - 5 \times 2 = - 4 + x \\ - 10 + 4 = x \\ x = - 6 \\ \\ 4 = \frac{2 + y}{2} \\ 4 \times 2 = 2 + y \\ 8 = 2 + y \\ 8 - 2 = y \\ y = 6 \\ \\ (x, \: \: y) = ( - 6, \: \: 6)[/tex]
Thus, the coordinates of point B are (-6, 6).
The coordinate of B is (-6, 6) if the midpoint of AB is M(-5, 4) and the coordinates of A are (-4, 2),
What is an ordered double?It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).
We have:
The midpoint of AB is M(-5, 4).
The coordinate of A is (-4, 2)
Let the coordinate of B is (x, y)
By using the midpoint property:
(-4+x)/2 = -5
-4 + x = -10
As we know, the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
-4 + x = -10
It is a linear equation in one variable:
x = -6
Similarly for y:
(2+y)/2 = 4
2 + y = 8
y = 6
The coordinate of B is (-6, 6)
Thus, the coordinate of B is (-6, 6) if the midpoint of AB is M(-5, 4) and the coordinates of A are (-4, 2),
