Answer:
0.01
Step-by-step explanation:
Your equation is 50 / x = 5,000
You are able to switch this around to 50 / 5,000 = x
Because you know that a x b = c is the same as b x a = c
When you divide 50 by 5,000, you get 0.01
So, 50 divided by 0.01 will get 5,000
Answer:
∠5
Step-by-step explanation:
Complementary angles are angles that:
- sum to 90°
- make a right angle
Given this information, angles 2, 3, and 4 are already right angles. That leaves angle 5 and angle 1 to be complementary with each other, as they form a right angle.
Have a lovely rest of your day/night, and good luck with your assignments! ♡

Number 4 i think
Step-by-step explanation:
Answer:
Probably unequal ( B )
Step-by-step explanation:
<u>experimental group = 10</u>
using 85% ethanol gasoline
mean = 240 pounds per 100 miles
standard deviation = 20 pounds
<u>control group = 14 vehicles </u>
using regular gasoline
mean = 252 pounds per 100 miles
standard deviation = 15 pounds
comparing the sample variance of each group shows that they are probably unequal using the equation below
Variance for a sample set of data = ∑ ( x - X ) ^2 / n - 1
where n = number of events
X = mean value
x = value of events
