Answer: Jim is <span>15 years old

Jim = 15 years old, 
</span><span>Dad is 4 times as old as his son Jim = = 15 x 4 = 60

In 10 years, Jim = 15 + 10 =25 years old
Dad = 60 + 10 = 70

</span><span>Dad's age will be 20 years more than twice Jim's age
</span><span>
Dad's age = 20 + 2(25) = 70

The correct answer is 15 years old. If Jim is currently 15 years old, then his dad is 60 years old. That means that in 10 years, Jim will be 25 and Dad will be 70. Seventy is equal to 25 times 2 plus 20.

2x + 5 = 11
First lets put like terms together!
subtract 5 by both sides
2x = 6
Then we have to get x by itself, in order to do this we divide by 2
x = 3

21+ 6m=3(m-1) not sure what to do here
castortr0y [4]

Answer:

M=-8

Step-by-step explanation:

21+6m=3(m−1)

Step 1: Simplify both sides of the equation.

21+6m=3(m−1)

21+6m=(3)(m)+(3)(−1)(Distribute)

21+6m=3m+−3

6m+21=3m−3

Step 2: Subtract 3m from both sides.

6m+21−3m=3m−3−3m

3m+21=−3

Step 3: Subtract 21 from both sides.

3m+21−21=−3−21

3m=−24

Step 4: Divide both sides by 3.

3m/3=-24/3

M=-8

The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. The measurements are in tons
Y_Kistochka [10]

Answer:

1.

A. H0 :  μ1 = μ2 = μ3

Ha : μ1 ≠ 2μ ≠ μ3

2. Test Statistics = 95%

3. Critical F-Value = 3.76

4. P-Value = 2.32

5. Conclusion : Reject the null hypothesis

6. Type of vehicle does effect the amount of green house gas emissions.

Step-by-step explanation:

The correct order of the steps of a hypothesis test is given following  

1. Determine the null and alternative hypothesis.

2. Select a sample and compute the critical value F-test for the sample mean.

3. Determine the probability at which you will conclude that the sample outcome is very unlikely.

4. Make a decision about the unknown population.

These steps are performed in the given sequence to test a hypothesis.

The null hypothesis is rejected or accepted on the basis of level of significance. When the p-value is greater than level of significance we fail to reject the null hypothesis and null hypothesis is then accepted. It is not necessary that all null hypothesis will be rejected at 95% level of significance. To determine the criteria for accepting or rejecting a null hypothesis we should also consider p-value.
