Answer:
B. 8
Step-by-step explanation:
By evaluate, they mean substitute in the values and solve.
x + 3y - n
= 10 + 3(2) - n
= 10 + 6 - 8
= 8
Please lmk if you have questions.
Answer:
I got 8, but I'm not sure.
Step-by-step explanation:
So I first did -6 + 5, and I got -1 as an answer. Then I did -1 plus 9 because both sides need to be equal. I wrote that x = 8 but that wasn't an option. I'm not sure if this was helpful and I'm really sorry if it's not.
Hello!
To do this you will pick an x value, multiply it by the slope and add the y- intercept. Let's try 0.
y=4(0)-1
y=-1
So here, an ordered pair could be (0,-1)
We can try this again for different x-values.
y=4(1)-1
y=3
This gives us the ordered pair (1,3)
y=4(100)-1
y=399
This would give us the ordered pair (100,399)
I hope this helps!
Answer: 29.916 minutes
Step-by-step explanation:
Given the following :
Mean of distribution = 17.8 minutes
Standard deviation of distribution = 5.2 minutes
Percentage of customers to give free lube and oil change service should not exceed 1% if the customer waits beyond the guaranteed time ;
Length of guarantee :
Since % of customers should not exceed 1%
Then probability of not being chosen = (1 - 0.01) = 0.99
Using the z table to find the Zscore of 0.99,
Zscore of 0.99 = 2.33
This is 2.33 standard deviations above the mean
(2.33 × standard deviation) + mean value
(2.33 × 5.2 minutes) + 17.8 minutes
12.116 + 17.8
= 29.916 minutes
Answer:
15
Step-by-step explanation:
26.95-8.85=21.1/1.5=14.06 repeating
You can't have 14.06 repeating refills so add 1 to 14 to get 15.
