Answer:
C) Real numbers from 0 to 8.
Step-by-step explanation:
We have been given a graph between depth (dependent variable) and time (independent variable). We need to figure out the domain of the given graph.
We know that domain is the set of values of independent variable for which the graph produces a finite value of dependent variable.
From the graph, we can see that for values of time between 0 and 8 minutes, the graph produces a finite value of depth. Therefore, domain of the given graph is all real numbers between 0 and 8 (inclusive).
What percent of the first 10 natural numbers are prime numbers? Answer in a percent please.
:)
So the first 10 are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Since a prime number is only divisible by 1 and itself and greater than 1, our answers are 2, 3, 5, and 7. That's 4 numbers, or 4/10=0.4 of the 10. Since percentage is based out of 1, we can multiply 0.4 by 100 to get 40%. I hope that Helped :)
8. The amount of a person’s paycheck p varies directly with the number of hours worked t. For 22 hours of work, the paycheck is $126.50. Write an equation for the relationship between hours of work and pay.
First you would need to find out how much there are paid by the hour, which in this case is $5.75. So the equation would be 5.75t = p, then insert the 22 hours of work to the equation 5.75(22) = p, last solve the answer by mutiply the 5.75(22) which equals 126.50. .

13 + 11s = -15 + 8s − 20
Answer,
S = -16
Explanation,
Step 1: Simplify both sides of the equation.
13 + 11s = − 15 + 8s − 20
13 + 11s = − 15 + 8s + − 20
11s + 13 = (8s) + (− 15 + − 20) (Combine Like Terms)
11s + 13 = 8s + − 35
11s + 13 = 8s − 35
Step 2: Subtract 8s from both sides.
11s + 13 − 8s = 8s − 35 − 8s
3s + 13 = − 35
Step 3: Subtract 13 from both sides.
3s + 13 − 13 = − 35 − 13
3s = − 48
Step 4: Divide both sides by 3.
3s/3 = −48/3
s = -16

There are 10 marbles total.
You picked a marble and replaced it 50 times, so you have:
9/50 were purple
16/50 were orange
6/50 were yellow
19/50 were green
Multiply those by the number of marbles:
10*9/50 = 1 4/5 purple, round to 2
10*16/50 = 3 1/5 orange, round to 3
10*6/50 = 1 1/5 yellow, round to 1
10*19/50 = 3 4/5 green, round to 4
2+3+1+4 = 10
So you can say that there are 2 purples, 3 oranges, 1 yellow, and 4 green marbles.

At Binh's Greenhouse in early spring, there are many greenhouse plants to repot and many outside plants to water. If it takes Binh 5 minutes to repot each plant and 2 minutes to water each plant, and he has at most 2 hours before the greenhouse opens, what inequality represents the time Binh has to repot and water the plants before the greenhouse opens? Let x represent the number of plants to repot, and y represent the number of plants to water.
2*y + 5*x < 2 hours But the units are not the same. The left side contains minutes and the right hours.
2y + 5x < 2*60
2y + 5x < 120 <<<<< Answer
Answer:
5x + 2x < 120
Step-by-step explanation:
Given:
Binh takes 5 minutes to repot each plant and 2 minutes to water each plant.
He has at most 2 hours.
Here "at most" represents by the inequality "<"
Let's convert 2 hours into minutes.
1 hour = 60 minutes
2 hours = 2×60 minutes = 120 minutes
Let x represent the number of plants to repot, and y represent the number of plants to water.
So, the given situation represented by
5x + 2x < 120
What is the difference between a linear function and a nonlinear function? And what each looks like when represented as a table and as a graph
A linear function has points leading up or down in more of a line. nonlinear is more scattered. Hope this helps!
Answer:
Sample Response: A linear function has a constant additive rate of change, while a nonlinear function does not. For a table of values to be linear, the dependent variable must have a constant rate of change as the independent variable increases by 1. On a graph, the function must be a straight line to be linear.
A linear function has a constant additive rate of change.
A nonlinear function does not have a constant additive rate of change.
The graph of a linear function is a straight line, while a nonlinear graph is curved.
The dependent variable in a linear table has a constant additive rate of change as the independent variable increases by 1.

Name the property of real numbers illustrated by the equation 5(x-3)=5x-15
This is known as the distributive property.
When you have a number outside of parentheses, (typically when there's a variable either inside or outside the parentheses), you can apply the number outside the parentheses to each term inside the parentheses, and the answer will still be equal.
Distributive Property is your answer.
In the case of "5(x - 3)", the parenthesis cannot be simplified, because you cannot combine a number and variable. To simplify, you must distribute the outside number (5), too all terms within the parenthesis
5(x - 3) = 5(x) + 5(-3)
Simplify.
5(x) = 5x
5(-3) = -15
5x - 15 is the answer (true, it makes the equation true)
Distribute Property is your answer

Only (-2,4)
(Choice B)
B
Only (-3,5)
(Choice C)
C
Both (-2,4) and (-3,5)
(Choice D)
D
Neither
Answer:
B.- Only (-3,5)
Step-by-step explanation:
In an ordered pair the first coordinate is the [tex]x[/tex] coordinate, and the second coordinate corresponds to the [tex]y[/tex] coordinate.
Then we must substitute the given value of [tex]x[/tex] in the equation and verify that we get in return the defined value for [tex]y[/tex].
the options are
[tex](-2,4)[/tex]in this one [tex]x = -2[/tex], and [tex]y=4[/tex], so let's confirm:
[tex]y=-3x-4\\y=-3(-2)-4\\y=-6-4\\y=2[/tex]this is not a solution since the [tex]y[/tex] values are not the same.
[tex](-3,5)[/tex]in this one [tex]x= -3[/tex] and [tex]y=5[/tex], let's also confirm:
[tex]y=-3(-3)-4\\y=9-4\\y=5[/tex]in this one the values for [tex]y[/tex] are equal, this is a solution for the equation.

A consumer analyst reports that the mean life of a certain type of alkaline battery is no more than 63 months. Write the null and alternative hypotheses and note which is the claim.
Solution-
The given statement,
the mean life of a certain type of alkaline battery is no more than 63 months.
Every hypothesis test carries two opposing statements, or hypothesis, about a population parameter. The first hypothesis is called the null hypothesis.
Null hypothesis always states that the population parameter is equal to the claimed value.
If the null hypothesis is rejected, then the alternative hypothesis is going to be claimed.
[tex]\text{Null hypothesis}=H_0:\mu =63[/tex]
[tex]\text{Alternative hypothesis}=H_1:\mu >63[/tex]
In this case, the alternative hypothesis is the claim.
The null hypothesis states that the mean life of the alkaline battery is 63 months or more. The alternative hypothesis states that the mean life of the alkaline battery is less than 63 months.
Explanation:The null hypothesis, denoted as H0, is the statement that the mean life of the alkaline battery is 63 months or more. The alternative hypothesis, denoted as Ha, is the statement that the mean life of the alkaline battery is less than 63 months. The claim in this case is the alternative hypothesis Ha.
Vanessa buys a strip of 25 postage stamps. The strip of stamps is 21 7/8 inches long. How long is a strip after Vanessa uses 1 stamp?
Answer:
7/8
Step-by-step explanation:
The strip is 21 7/8 inches long. You need to make this into an improper fraction so you multiply 21x8= 168 and then add 7 to that which = 175. So the improper fraction is 175/8 (instead of 21 7/8). Now you just divide 175 by 25 which is 7. Each stamp is 7/8 inches long.
To find the new length of the strip after Vanessa uses one stamp, we first divide the initial length of the strip by the total number of stamps to find the length of one stamp. We then subtract this from the original length of the strip. The new length is 21 inches.
Explanation:This question is asking how long a strip of stamps is after Vanessa uses one of them. Given that the original strip is 21 7/8 inches long and includes 25 stamps, we can find the length of one stamp by dividing the total length of the strip by the total number of stamps. So, the length of one stamp is 21 7/8 ÷ 25.
We then subtract the length of this one stamp from the original length of the strip to find the new length:
Length of one stamp = 21 7/8 inches ÷ 25 = 0.875 inchesNew length of the strip = 21 7/8 inches - 0.875 inch = 21 inchesThe new length of the strip, after Vanessa uses one stamp, is therefore 21 inches.

A contractor wants to replace the baseboard of a room whose length is 15 feet and width is 6 feet. How much will the baseboard cost if the material they will use is $5 per foot ?
It will cost $18.
15*6=90
90/5=18
It will cost $18.
The cost of the baseboard for $5 per foot whose length is 15 feet and width is 6 feet will be $ 210.
Given that:
Length of the baseboard = 15 feet
Width of the baseboard = 6 feet
The total space occupied by the baseboard can be calculated using the perimeter of the baseboard.
The perimeter of a rectangle can be calculated using the formula:
[tex]Perimeter = 2 \times(Length + Width)[/tex]
= [tex]2 \times(15 + 6)[/tex]
= [tex]2 \times 21[/tex]
= 42 feet
The cost of the baseboard can be calculated by multiplying the total length (42 feet) by the cost per foot ($5)
[tex]Cost \ of \ baseboard = Total\ length\times Cost \ per \ foot[/tex]
=[tex]42 \times 5[/tex]
= $210
Therefore, the cost of the baseboard for the room would be $210.

HELP 1/7z+2=-6/7z what’s the solution set please send help I’m suffocating under homework
Isolate the z. Note the equal sign. Subtract 1/7z to both sides
1/7z (-1/7z) + 2 = -6/7z (-1/7z)
2 = -6/7z - 1/7z
Simplify. Combine like terms
2 = -7/7z
2 = -1z
Isolate the z. Divide -1 from both sides
(2)/-1 = (-1z)/-1
z = 2/-1
z = -2

We know 15 minutes contain 15*60 = 900 seconds, the time for 85 blinks
Then the time for each blink t = 900/85
Time elapsed in seconds for 51 blinks is then 51*t = 900*51/85 = 540 seconds
As the answer wants to know the seconds, find the seconds. 15 * 60 = 900. We know he blinks 85 times in 900 seconds, so divide 900 by 85 to find the rate at which George blinks. 900 / 85 = 10.588. Multiply 10.588 by 51 to find the number of seconds for 51 blinks. 51 * 10.588 = 539.988.

true of false the first distribution shown below has a smaller standard deviation than does the second distribution. 11,12,13,14,15,16,17,18,19,20,21,22,111,112,113,114,115,116,117,118,119,120,121,122
false becasue 11,12,13,14,15,16,17,18,19,20,21, and 22 is bigger and 111,112,113,114,115,116,117,118,119,120,121, and 122 is smaller.
Answer:
False
Step-by-step explanation:
Standard Deviation is the square root of sum of square of the distance of observation from the mean.
[tex]Standard deviation(\sigma) = \sqrt{\frac{1}{n}\sum_{i=1}^{n}{(x_{i}-\bar{x})^{2}}[/tex]
where, [tex]\bar{x}[/tex] is mean of the distribution.
Here, First distribution is 11,12,13,14,15,16,17,18,19,20,21,22
and Second distribution is 111,112,113,114,115,116,117,118,119,120,121,122
The mean of first distribution is 16.5
and mean of second distribution is 116.5
So the standard deviation of first distribution is 3.605
and the standard deviation of second distribution is 3.605
Hence, standard deviation is same for both distribution.
