Answer:

102 and 109

Step-by-step explanation:

create an equation to solve:

(x-7) + x = 225

2x -7 = 225

+7 +7 add 7 to both sides

2x = 218

2 2 divide both sides by 2

x = 109

109 is the first number

then you solve for the other number

x-7= ?

109 - 7 = 102

102 is the 2nd number

There is a 0.9989 probability that a randomly selected 32 year old male lives through the year. A life insurance company charges

densk [106]

Answer:

$53.83

Step-by-step explanation:

The question is "What is the expected value for the insurance company?"

The expected value is the sum of the product of each possibility and its probability.

Thus, we have:

The probability of living is 0.9989 and its value is 153

THe probability of dying is (1-0.9989=0.0011) and its value is -90,000

Now, the expected value is:

E(x) = (0.9989)(153) + (0.0011)(-90,000) = $53.83

Calculate the discount percent on an article which cost ¢60,000 but was reduced to ¢45,00

belka [17]

Answer:

Assuming you mean from $60 to $45, that would be 25%.

Step-by-step explanation:

We can use the simple formula: $\frac{NEW-OLD}{OLD} *100$

In this case: $\frac{45-60}{60} *100 = -25$

Which means there is a 25% discount.

A campsite is 12.88 miles from a point directly below Mt. Adams. If the angle of elevation is 15.5° from the camp to the top of

nata0808 [166]

Answer:

3.57 miles

Step-by-step explanation:

Please consider the attachment.

We have been given that a campsite is 12.88 miles from a point directly below Mt. Adams. The angle of elevation is 15.5° from the camp to the top of the mountain. We are asked to find the height of the mountain.

We can see from the attachment that h is opposite side to angle 15.5 degrees and 12.88 miles in adjacent side.

We know that tangent relates opposite side of right triangle with its adjacent side.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$
