We want to find $\mathbb P(X\ge6)$ , where $X$ is a binomial distribution with $n=100$ and $p=0.015$ . So

$\mathbb P(X\ge6)=1-\mathbb P(X$

A salesperson earns a commission based on the number and type of vehicle sold. A person selling 6 cars and 3 trucks earns $4,800

madam [21]

4800 divide by 3=1600 (2 cars 1 truck)

4600-1600-3000 (6 cars)

3000 divide by 3 = 1000(2cars)

1000 times 2=2000(4 cars )

4800-2000-2800 (2 cars 3 trucks)

$2,800 is your answer

The measure of < A is 45 degree

VashaNatasha [74]

We are given $\triangle ABC \cong \triangle EFG$

The order of the letter sequence is important. The letters pair up based on how they are arranged. We see that A and E are the first letters of the sequences. So this means that angles A and E are the same measure

angle A = angle E

3x+20 = 5x-80

3x-5x = -80-20

-2x = -100

x = -100/(-2)

x = 50

Use this x value to find the measure of angle A

angle A = 3x+20

angle A = 3(50)+20

angle A = 150+20

angle A = 170 degrees

<h3>Therefore, the statement "the measure of angle A is 45 degrees" is false.</h3>

And airplanes at altitude change -370 ft over 7 minutes what was the mean change of altitude in feet per minute?

Reil [10]

We have that
 [the mean change of altitude]=[change in altitude]/[time]
 [the mean change of altitude]=[-370]/[7]---------------> -52.86 ft/minute

the answer is -52.86 ft/minute (the negative sign means that the plane is descending)
