Answer:
Expectation=240
standard deviation=3.098
Step-by-step explanation:
This is a binomial probability function with n=250 and probability of success is 96%
-The expected value is calculated as:
Hence, the expected germination is 240 seeds
b. From a above, we have the value of p=0.96 and n=250.
The standard deviation of germination is therefore calculated using the formula:
Hence, the standard deviation of germination is 3.098
Answer: At least 7
Step-by-step explanation:
A good tip is to cut the same shape and fold it and count how many symmetry :)
<h3>
Answer: Choice A which is (m+6)^2</h3>
Explanation:
Think of two numbers that multiply to 36 and add to 12. Those two numbers are 6 and 6
6+6 = 12
6*6 = 36
So we can factor it into (m+6)(m+6). Use the FOIL rule to expand it out to get m^2+12m+36 back again.
The expression (m+6)(m+6) is the same as (m+6)^2
Answer:
c
Step-by-step explanation:
did the test
Step-by-step explanation:
For oil container in the shape of a cylinder
radius (r) = 6 m
height (h) = 7 m
TSA of Cylinder
= <em><u>2πr ( r + h) </u></em>
= 2 * 3.14 * 6 ( 6 + 7)
= 2 * 3.14 * 6 (13)
= 2 * 3.14 * 6 * 13
= 489.84 square meter
<em>Now, </em><em> </em>
the total cost of the steel will be $18,613.92.
= 18613.92/489.84
= $38
Thus, The TSA of a cylinder is 489.84 square meter and $38 will the steel cost per square meter.
