What is the equation of the line in slope-intercept form?
O Y=2x-8
O y = 2x+8
O y=8x-2
O y = 8x+2
Step-by-step explanation:
since b = 8, it has to be
y = 2x + 8
that was the whole point of the exercise, as the general slope-intercept form is
y = mx + b
you determined m = 2 and b = 8, so there is your answer. I am not sure where your problem was, as you solved the actual important part yourself.
a) In the first event, the eighth graders are running a baton relay race with three other classmates. The team’s top speed for each leg is 56.81 seconds, 59.22 seconds, 57.39 seconds, and 60.11 seconds. Use the information to predict the team’s best time for the race
Answer:
58.4 seconds
Step-by-step explanation:
Find the average of all the seconds by dividing the sum of the seconds by 4
Answer:
233.53 s
The sum of best times for the legs is ...
56.81 +59.22 +57.39 +60.11 = 233.53 . . . seconds
Without additional information about the effects of training or the normal variation in times, this is the best prediction we can make.

A pizza shop sells three sizes of pizza, and they track how often each size gets ordered along with how much they profit from each size. Let X represent the shop's profit on a randomly selected pizza. Here's the probability distribution of X along with summary statistics:
Small Medium Large
X = profit ($) 4 8 12
P(X) 0.18 0.50 0.32
Mean: μX = $8.56
Standard deviation: σx =$2.77
The company is going to run a promotion where customers get $2 off any size pizza. Assume that the promotion will not change the probability that corresponds to each size. Let Y represent their profit on a randomly selected pizza with this promotion. What are the mean and standard deviation of Y?
Answer:
The mean and standard deviation of Y is $6.56 and $2.77 respectively.
Step-by-step explanation:
Consider the provided information.
Let Y represent their profit on a randomly selected pizza with this promotion.
The company is going to run a promotion where customers get $2 off any size pizza.
Therefore, [tex]Y=\text{Profit}-\$2[/tex]
[tex]Y=X-\$2[/tex]
So the mean will be reduced by 2.
[tex]\mu_Y=\mu_X-\$2[/tex]
[tex]\mu_Y =\$ 8.56 - \$2[/tex]
[tex]\mu_Y =\$6.56[/tex]
If we add or subtract any constant number from a given distribution, then the mean is changed by the same number(i.e constant number) but the standard deviation will remain the same.
Therefore [tex]\sigma_Y=\sigma_X=2.77[/tex]
Hence, the mean and standard deviation of Y is $6.56 and $2.77 respectively.

Step-by-step explanation:
You weigh a gallon of liquid in science class and learn that it is approximately 7.7 pounds. You pass the liquid to the next group, and then realize that your teacher wanted an answer in kilograms, not pounds. Complete the explanation of how you can adjust your answer without weighing the liquid again. Then give the weight in kilograms. If necessary, round your answer to the nearest tenth.
only right anwres
Answer:
7.7 pounds = 3.5 kilograms
Step-by-step explanation:
Given that,
Weight of a gallon of liquid = 7.7 pounds
We need to find weight in kilograms.
We must know the relation between pounds and kilograms and it is as follows :
1 kilogram = 2.20 pounds
or
1 pounds = (1/2.2) kilograms
7.7 pounds = (7.7/2.2) kilograms
= 3.5 kilograms
Hence, 7.7 pounds is equal to 3.5 kilograms.
Find the measure of each angle in the problem: complementary angles with measures 4x and 5x-18 degrees
Answer:
42 degrees and 48 degrees
Step-by-step explanation:
If they are complementary, that means they add up to 90 degrees, so
4x + 5x - 18 = 90,
Solving,
9x - 18 = 90
add 18 to both sides
9x = 108
divide both sides by 9
x = 12
Now, to find the angle measures of each you have to substitute x = 12 into both angles.
4x --> 4 * 12 = 48 degrees
5x - 18 --> 5 * 12 - 18 --> 60 - 18 --> 42 degrees

Answer:
There is one solution (4,0)
Step-by-step explanation:
First, we will try to solve this system of equations.
I will rearrange 2x-5y=8 to isolate -5y.
The new equation would be 5y=2x-8.
Now we will add
2x -8 = 5y
with
-2x+8=5y
We get 0 = 10y
Divide by 10 and we get y = 0.
Now that we know the value of y, lets solve for x.
2x-8=5(0)
2x-8=0
Add 8
2x=8
Divide by 2 to isolate x
x = 4.
x=4 and y=0
The solution is (4, 0)
