Answer:
The value of b will be squared
Step-by-step explanation:
Recall that the quadratic formula is 
You will see that the only squared coefficient is b.
Okay, I went through a lot of work to try solving this, so here goes!
First, turn the mixed numbers into improper fractions.
6 1/4 --> 25/4
3 3/5 --> 18/5
Next, we need to multiply the two improper fractions together.
25 x 18 450
--- --- = ---
4 x 5 20
Then, we need to turn 450/20 into a mixed number. To do this, we divide.
450/20=22 10/26
We're almost done. Last step is to simplify the mixed number, specifically 10/26. We need to find GCF of 10 and 26, which is 2.
10/2=5
26/2=13
= 5/13
FINAL ANSWER - 22 5/13
You're welcome.
95% fall within 2 standard deviations of the mean
Answer:
n ≥ -3
Step-by-step explanation:
So, divide -27 by 9n and the answer to that is -3, because when you're dividing a negative number and a positive, the answer would always be negative.
This sign : ≥ means greater than or equal to, and because we are solving for n, -3 is equal to n.
Answer:
μ = 1.877
Step-by-step explanation:
Data provided in the question:
Number of data samples, n = 10
Data: 2.18, 2.03, 1.56, 1.09, 1.56 ,2.28 ,1.62 ,2.02 ,2.11 ,2.32
Now,
Mean is calculated using the formula as:
Mean, μ = 
or
Mean, μ = 
or
Mean , μ = 
or
Mean , μ = 1.877
