Jethro walked 3 miles per hour for 2 hours. So you would want to do 3 x 2.
That equaling 6. So Jethro walked a total of 6 miles in two hours.
Randy walked 4 miles per hour for 3 hours. So you would want to do 4 x 3.
That equaling 12. So Randy walked a total 12 miles in three hours.
If you add 6 miles and 12 miles the boys would have walked a total of 18 miles together.
Hope you do good. Have a Tessariffic day.

If Jethro walked 3mph for two hours, than you multiply 3×2=6 miles

if Randy walked 4mph for 3 hours then 4×3=12 miles

Mph×the number of hours= miles

Also how would you round 2.59 to the nearest tenths ?

Maslowich

Answer:

2.6

Step-by-step explanation:

The tenths digit is the 5.

Drop every digit after the 5. You get 2.5

Now you need to see if the 5 stays as it is or if it goes up by 1 to 6.

The first digit after the 5 you dropped is 9. Since 9 is greater than 4, the previous digit goes up by 1, so the 5 becomes a 6.

The final answer is 2.6

This is used for the next few questions: The rating for the new scary movie has a scale of 0 to 10. The average response was tha

Pie

Answer:

The percentage that of people who gave the movie a rating between 6.8 and 8.8

P(6.8≤X≤8.8) = 83.9≅ 84 percentage

Step-by-step explanation:

Step(i):-

Mean of the Population = 8.3 points

Standard deviation of the Population = 0.5 points

Let 'X' be the random variable in normal distribution

Let X = 6.8

$Z = \frac{x-mean}{S.D} = \frac{6.8-8.3}{0.5} = -3$

Let X = 8.8

$Z = \frac{x-mean}{S.D} = \frac{8.8-8.3}{0.5} = 1$

The probability that of people who gave the movie a rating between 6.8 and 8.8

P(6.8≤X≤8.8) = P(-3≤Z≤1)

= P(Z≤1)- P(Z≤-3)

= 0.5 + A(1) - ( 0.5 -A(-3))

= A(1) + A(3) (∵A(-3)=A(3)

= 0.3413 +0.4986 (∵ From Normal table)

= 0.8399

Conclusion:-

The percentage that of people who gave the movie a rating between 6.8 and 8.8

P(6.8≤X≤8.8) = 83.9≅ 84 percentage
