Answer:

4(x-4)

Step-by-step explanation:

Both 4x and 16 have a positive 4 in common so you would take it out and that leaves you with x and -4 so those go in the parenthesis.

A.

4•x is 4x
4•-4 is -16
So, 4x-16

lorena lifeguards at a lap pool that is 25 yards long, 10 ards wide, and 2 yards deep. There is a drain around he entire top edg

Varvara68 [4.7K]

The true statements about the pool are

The drain is best measured using perimeter
The area of the cover is 250 square yards
One edge of the pool measures 10 yd

<h3>How to determine true statements?</h3>

The given parameters are:

Length = 25 yards
Width = 10 yards
Depth = 2 yards

To measure the drain, we simply calculate the perimeter of the edge of the pool.

This means that (a) is correct

When the volume is calculated, the unit is cubic yard or yd³.

This means that (b) is wrong

The area of the cover is:

Area = Length * Width

This gives

Area = 25 yards * 10 yards

Evaluate

Area = 250 square yards

This means that (c) is correct

The length of the drain is calculated as:

Perimeter = 2 *(Length + Width)

This gives

Perimeter = 2 * (25 + 10)

Evaluate

Perimeter = 70

This means that (d) is wrong

Lastly (e) is correct, because the width of pool is 10 yards

Help? I know number 3 is yes but I don’t remember why.

3. Yes, the shapes are congruent, because all the corresponding sides are the same lengths.

The American Veterinary Association claims that the annual cost of medical care for dogs averages $100 with a standard deviation

Taya2010 [7]

Answer:

The probability that the cost for someone's dog is higher than for the cat is 33.2%.

Step-by-step explanation:

With the data given, we know that the difference in cost of medical care of dogs and cats have a normal distribution with μ=-20 and σ=46.

To know the probability of the cost for the dog is higher than the cat, we have to calculate the probability of P(d>0).

Then we have to calculate z, and look up in a standarized normal distribution table.

Calculate z:

$z=\frac{X-\mu}{\sigma}=\frac{0-(-20)}{46}=\frac{20}{46}= 0.4348$

The probability of the difference being higher than 0, we have:

$P(d>0)=P(z>0.4348)=0.33185$

We can say that the probability that the cost for someone's dog is higher than for the cat is 33.2%.
