How to find the area of a square ABC D

____ [38]

Answer:

The answer to your question is 13 u²

Step-by-step explanation:

We know that the small triangle is surrounded by right triangles so we can use the Pythagorean theorem to find the lengths of the small triangle

AD² = 3² + 2²

Simplify

AD² = 9 + 4

AD² = 13

AD = $\sqrt{13}$

Find the area of the square

Area = side x side

Area = AD x AD

Area = $\sqrt{13} x \sqrt{13}$

Area = 13 u²

Step-by-step explanation:

we have:

5(2f - 6g)

we apply distributive property:

5(2f - 6g)

5*2f+5*(-6g)

finally we have:

10f-30g

The cycle time for trucks hauling concrete to a highway construction site is uniformly distributed over the interval 40 to 75 mi

jeka57 [31]

Answer:

0.8333 = 83.33% probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:

$P(X > x) = \frac{b - x}{b - a}$

Uniformly distributed over the interval 40 to 75 minutes.

This means that $a = 40, b = 75$

It is known that the cycle time exceeds 45 minutes

This means that we can use $a = 45$

What is the probability that the cycle time exceeds 50 minutes?

$P(X > 50) = \frac{75 - 50}{75 - 45} = 0.8333$

0.8333 = 83.33% probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes

Sue bought 3 t shirt for 8$ each. she paid with a $50 bill how much change should she get

muminat

Hi there!

First we need to calculate how much the 3 T-shirts cost and subtract that from the amount she paid to find the change.

First, we multiply to find the coats of the T-shirts.

3 × 8 = 24

Now, we subtract 24 from 50.

50 - 24 = 26

So, she got $26 of change.

Hope this helps!

Find the probability of spinning a 2 and 4 and rolling a 6?

Tasya [4]

Answer:

Just by simply adding the two quantities you can get the net change. $67.12 +(addition sign because we want the net change) $2.56= $69.68. The last number is the net change!
