N = number of seeds planted
P = probability of germination
K = number that germinated
Using probability calculation:
p(x = k) = (n k) x 0.90^K x 0.10^n-k
p(10) = (12 10) x 0.90^10 x 0.10^2
P(10) = 0.2310
Answer:
Option C.
Step-by-step explanation:
For a given set of N elements:
{x₁, x₂, ..., xₙ}
The mean is given by:

And the variance is given by:

Then for our set:
{70, 80 ,75, 75, 80}
We have 5 elements, then N = 5
The first thing we need to find is the mean.

Then the variance will be:

The correct option is C, 14.
Answer:
1 7/10 is your answer.
Step-by-step explanation:
What you have to do is find the GCF.
10 goes into both 5 and 10
<em>8/10 + 9/10 = </em>
<em>17/10 =</em>
1 7/10 is your answer.
Hello!
You have to find what a and b are
3a + 4a = 14
b + 6b = 21
Lets do a first
3a + 4a = 14
Combine like terms
7a = 14
Divide both sides by 7
a = 2
Now lets do b
b + 6b = 21
Combine like terms
7b = 21
Divide both sides by 7
b = 3
Put a and b into the third equation
7( 2 + 3) =
Do what is in parenthesis first
7(5) =
Multiply
35
The answer is 35
Hope this helps!
