Answer:
Step-by-step explanation:
Let's solve for x.
−3x+2y=−10
Step 1: Add -2y to both sides.
−3x+2y+−2y=−10+−2y
−3x=−2y−10
Step 2: Divide both sides by -3.
−3x
/−3

Answer:

Step-by-step explanation:
To find the derivative of the function
you must:
Step 1. Rewrite the logarithm:

Step 2. The derivative of a sum is the sum of derivatives:

Step 3. The derivative of natural logarithm is 

Step 4. The function
is the composition
of two functions
and 
Step 5. Apply the chain rule 

Return to the old variable:

The derivative of a sum is the sum of derivatives:

Step 6. Apply the power rule 


Thus, 
After 40 miles the rental cost for both is the same
Answer:
As the calculated F lies in the acceptance region therefore we conclude that there is not sufficient evidence to support the claim that the variability in concentration may differ for the two companies. Hence Ha is rejected and H0 is accepted.
Step-by-step explanation:
As we suspect the variability of concentration F - test is applied.
n1=10 s1=4.7
n2=16 s2=5.8
And α = 0.05.
The null and alternate hypothesis are
H0: σ₁²=σ₂² Ha: σ₁²≠σ₂²
The null hypothesis is the variability in concentration does not differ for the two companies.
against the claim
the variability in concentration may differ for the two companies
The critical region F∝(υ1,υ2) = F(0.025)9,15= 3.12
and 1/F∝(υ1,υ2) = 1/3.77= 0.26533
where υ1= n1-1= 10-1= 9 and υ2= n2-1= 16-1= 15
Test Statistic
F = s₁²/s₂²
F= 4.7²/5.8²=0.6566
Conclusion :
As the calculated F lies in the acceptance region therefore we conclude that there is not sufficient evidence to support the claim that the variability in concentration may differ for the two companies. Hence Ha is rejected and H0 is accepted.
