Answer:
C. He should run a T-test, and approximating it with a normal distribution would be inappropriate.
Step-by-step explanation:
We are told that the standard deviation is unknown.
Now in statistics, when we know the standard deviation, then we use a Z-test but when we don't know the standard deviation, then we will use a t-test.
Now, the t-test assumes a normal distribution for difference in mean of samples but it doesn't assume so for population.
Thus, we will run a t-test and doesn't need to approximate with a normal distribution.
The bottom is 2 times the size of the first one
2 (2x - 9) = 14
Distribute
4x - 18 = 14
Add 18
4x = 32
Divide by 4
x = 8
18 total cups of antifreeze and 9 cups of water hope this helps
Step-by-step explanation:
so for every 2 cups of antifreeze there is 1 cup of water(example for measurement) and 27 cups total so what i would do is guess and check so 2 times 9 plus nine is 27
Answer:
$12,000
Step-by-step explanation:
Kabore wants to make $700 this week. We can subtract 100 from that amount because his base pay is $100.
700 - 100 = 600
This leaves us with 600. Kabore has to make $600 from his sales. However, he only gets paid 5% of his sales. So, 600 is worth 5% of his sales. This can be represented in an equation, where x represents his sales and 0.05 is 5% in decimal form:
= 0.05
Multiply both sides of the equation by x to isolate it on one side:
600 = 0.05x
Divide both sides by 0.05 to find the value of x:
12000 = x
Kabore needs to sell $12,000 worth of product if he wants to make $700 this week.
Hope this helps :)
