Answer:
yes because all rectangles have 4 sides
Answer:
30
Step-by-step explanation:
Given :
Mean, m = 30 metric tons
Standard deviation (s) = 1.5 metric ton
Sample size, n = 4
Since the impact force in the test model is normally distributed, the shape of the sampling distribution will also be approximately normal with a mean equal to the mean of the test model.
Hence, the sample mean impact force will be equal to the population mean.
Therefore, sample mean = 30 ; population mean = 30
Answer:
Hi i think that the correct answer is B
Answer:
(2,21)
Step-by-step explanation:
y = 10.5x
plug 2 for x in the equation
y = 10.5(2)
then multiply 2 by 10.5
y=21
Answer:
x=4.8
This here you use Pythagorean Theorem.
Step-by-step explanation:
a^2+b^2=c^2
The longest side is c. And the two legs are a and b.
So it'd be 11^2+x^2=12^2
121+x^2=144
Subtract 121 from both sides.
x^2=23
Then take the √ of x^2 and 23
So √x^2=√23
x=4.8
Hope this helps
