Step-by-step explanation:

A.) 2+12=14

B.) (-3)(-8)=24 (A negative number times a negative number is positive.)

C.) 10-(-18) = 28 (Negative minus is plus.)

D.) -35÷5 = -7 (A negative number times or divided by a positive number results in a negative number.)

Pat can mow the grass on the football field in 45 minutes. Jordan can mow

Basile [38]

You set up the equation like this:

T/45+T/53=1

You find the least common factor of 53 and 45 and times both sides so you end up with this:

53T+45T= least common factor

Then add up 53T and 45T.

98T= least common factor

Then divide 98 from both sides. That will be your answer.

Sorry I didn't have enough time to find the least common factor but it is a number that they both go into. I would check to make sure I'm correct. I hope this helps!

The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 4. Approximately what

harkovskaia [24]

Answer:

78.88%

Step-by-step explanation:

We have been given that

$\mu=25,\sigma=4,x_1=20,x_2=30$

The z-score formula is given by

$z-\text{score}=\frac{x-\mu}{\sigma}$

For $x_1=20$

$z_1=\frac{20-25}{4}\\\\z_1=-1.25$

For $x_2=30$

$z_2=\frac{30-25}{4}\\\\z_2=1.25$

Now, we find the corresponding probability from the standard z score table.

For the z score -1.25, we have the probability 0.1056

For the z score 1.25, we have the probability 0.8944

Therefore, the percent of the trees that are between 20 and 30 years old is given by

0.8944 - 0.1056

= 0.7888

=78.88%
