The probability that the coin Jan takes out is a dime would be 100% or 3/3
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that Jan has three dimes In her pocket and nothing else. she takes one coin out of her pocket.
Picking with replacement, twice from 3 dimes.
Probability of picking a dime each time = 3/3
Which is 100 percent because there is nothing els.

The measure of the seventh angle in the heptagon is 125 degrees.
What is Polygon?A polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain.
We are given the measures of six angles in the heptagon, which are:
95, 107, 132, 138, 145, and 158 degrees
Sum of angles in Heptagon is 900 degrees.
To find the measure of the seventh angle, we can subtract the sum of the six known angles from the sum of all the angles in the heptagon:
Measure of the seventh angle = Sum of angles - Sum of known angles
Measure of the seventh angle = 900 degrees - (95 + 107 + 132 + 138 + 145 + 158) degrees
Measure of the seventh angle = 900 degrees - 775 degrees
Measure of the seventh angle = 125 degrees
Therefore, the measure of the seventh angle in the heptagon is 125 degrees.

The crew is taking 80 liters of water. There are 4 people on the crew. How many milliliters of water does each person get?
Answer:
Each people get 20,000 mili-litres of water.
Step-by-step explanation:
As , we know that
1 litre = 1000 mili-litre
As we have 80 litre of water
⇒ 80 litres = 80×1000 mili-litres
= 80,000 mili-litres
⇒ 80 litres = 80,000 mili-litres
∴ we have
Total water available in the crew = 80,000 mili-litres
As , there are 4 people in the crew
Let each people consume x mili-litre
⇒4x = 80,000 mili-litres
⇒x = [tex]\frac{80,000}{4} = 20,000[/tex] mili-litres
∴ we get
Each people gets 20,000 mili-litres of water.
Is the function linear or non linear?
Answer:
The function Has to Be Linear.
Step-by-step explanation:
The reason why the function has to be linear is because even though there is a slight curve the rest of the line is straight.
You need to look at the direction the line is pointing. Now say it was a line that had all kinds of wavey curves and loops that would be nonlinear.
I hope this helps you out. Let me know if linear is the correct answer, because if it isn't then that Assessment is crazy.

A data set consists of 2, 2, 3, 4, 5, 5, and 7. Then, 20 is added to the data set. The new value will have little effect on the , but it will raise the significantly.
Answer:
Median; mean.
Step-by-step explanation:
A data set consists of 2, 2, 3, 4, 5, 5, and 7. Then, 20 is added to the data set. The new value will have little effect on the median, but it will raise the mean significantly.
Let's find the median and mean from the original data;
x = 2, 2, 3, 4, 5, 5, 7.
F(x) = 2 + 2 + 3 + 4 + 5 + 5 + 7
F(x) = 28
[tex] Mean = \frac {F(x)}{7} [/tex]
[tex] Mean = \frac {28}{7} [/tex]
Mean = 4
Median is the middle number of a sorted array of numbers.
Median = 4
Now, let's find the median and mean from the new data;
x = 2, 2, 3, 4, 5, 5, 7, 20.
F(x) = 2 + 2 + 3 + 4 + 5 + 5 + 7 + 20
F(x) = 48
[tex] Mean = \frac {48}{6} [/tex]
Mean = 8
[tex] Median = \frac {4 + 5}{2} [/tex]
Median = 4.5
Therefore, the median increased from 4 to 4.5 while the mean increased significantly from 4 to 8.

3m−19+19=14+19
3m=33
Divide both sides by 3.
3m/3=33/3
m=11
Answer:
m=11
Step-by-step explanation:
We want to isolate m on the left side of the equation.
3m-19=14; add 19 to both sides, now you have:
3m=33; divide 33 by 3:

A type of electric car can travel 5 on 1 kilowatt hour of electricity. How many kilowatt hours of electricity would it take Helen to drive her electric car to her aunts house and back? Helen lives 70 miles from her aunt.
Answer:
28 kwh
Step-by-step explanation:
given that the care can travel 5 miles on 1 kwh, i.e
5 miles travelled -----> uses 1 kwh
hence to find the unit rate:
1 mile travelled ----> Uses 1 kwh ÷ 5 = 1/5 kwh
We are also given that Helen lives 70 miles away from her aunt.
Hence a return trip (i.e "to aunts house and back"), will be 70 x 2 = 140 miles
using the unit rate that we found above, we can find the number of kwh that is used to travel 140 miles
140 miles = 140 miles x unit rate
= 140 x 1/5
= 28 kwh
