i don’t understand what ? is. it’s pythagorean theorem and i know for this question, you HAVE to add, but i always get an answer

Sophie [7]

P1 = 10 m²

P2 = 22 m²

P3 = ?

According to Pythagoras' theorem:

P1 + P2 = P3

P3 = 10 m² + 22 m² = 32 m²

An insurance company charges Ted E. Bear $1400 per year for insurance on his home. The company has predicted that there is a 10%

Anna35 [415]

Answer:

$900

Step-by-step explanation:

The given parameters are;

The amount Ted pays per year for insurance on his home = $1,400

The value of the insurance policy = $5000

The chance that Ted will make a claim on the policy = 10%

The expected value is given as follows

Incidence Probability(p) Value(v) v × p

A claim is made 0.1 $5,000 - $1,400 = -$3,600 -$360

No claim 0.9 $1,400 $1260

Expected value is $1,260 - $360 = $900

The value the insurance company can be expected to make on average on the policy is $900

The probability distribution for a

Klio2033 [76]

Answer:

Step-by-step explanation:

The probability distribution in the second row simply shows the probabilities for each number in the first row.

To find the probability that x is between -5 and 5, you can add the probabilities -5 < x < 5.

P(-5) = 0.15

P(0) = 0.05

P(5) = 0.1

0.15 + 0.05 + 0.1 = 0.3

Write an equation of the line that is parallel to 3x + 9y = 7 and passes through the point (6, 4).

Ber [7]

First, rearrange the equation to standard line format
3x + 9y = 7
9y = -3x + 7
y = -3/9x + 7/9
y = -1/3x + 7/9

now we know the slope of the line (both the existing and the new parallel one, since they both have the same slope)

y = -1/3x + b

plug in the new point in and solve for b

4 = -1/3(6) + b
4 = -2 + b
b = 6

y = -1/3x + 6 is the equation for the parallel line

A boat takes 4 hours to go 12 miles upstream. It can go 32 miles downstream in the same time. Find the rate of the current and t

galina1969 [7]

The speed upstream is the difference between the boat speed and the current speed. It is (12 mi)/(4 h) = 3 mph.

The speed downstream is the sum of the boat speed and the current speed. It is (32 mph)/(4 h) = 8 mph.

The speed of the boat is the average of these: (3 + 8)/2 = 5.5 mph.

The speed of the current is that less the difference: 5.5 - 3 = 2.5 mph.

_____

<u>Check</u>

Boat + Current = 5.5 + 2.5 = 8 mph

Boat - Current = 5.5 - 2.5 = 3 mph
