What??????????????????????????????????
The <u>correct answer</u> is:
It is not a very strong fit.
Explanation:
The r-value, or correlation coefficient, tells us how closely our model fits the data.
The r-values range from -1 to 1. -1 is a perfect fit of a decreasing model; 1 is a perfect fit of an increasing model. 0 is no fit at all.
Since our r-value is 0.29, this is much closer to 0 than it is to 1 or -1; this means it is not a very strong fit.
Answer:
1.00434
Step-by-step explanation:
Given the following :
Given a normal distribution ;
Mean (m) = 1.0 liter
Standard deviation (σ) = 0.01 liter
Sample size (n) = 25
For 97% sample means (sm) = 0.97
Z = (m - sm) / s
Zcrit = 1 - (100% - 97%)/2
Zcrit = 1 - (0.03/2)
Zcrit = 1 - 0.015 = 0.985
The z score which corresponds to 0.985 = 2.17
Upper limit : m + z*(σ/√n)
Upper limit : 1.0 + 2.17*(0.01/√25)
Upper limit : 1. 0 + 2.17*(0.01/5)
= 1.0 + 2.17*0.002
= 1.0 + 0.00434
= 1.00434
Answer:
d=−bc+a/0.5bc
Step-by-step explanation:
Let's solve for d.
a=0.5bcd+bc
Step 1: Flip the equation.
0.5bcd+bc=a
Step 2: Add -bc to both sides.
0.5bcd+bc+−bc=a+−bc
0.5bcd=−bc+a
Step 3: Divide both sides by 0.5bc.
0.5bcd/0.5bc = −bc+a/0.5bc
d=−bc+a/0.5bc
