Answer:

C) 99 + 3x

Step-by-step explanation:

Since it's always going to cost 99, it'll stay like that since it's a constant

Since it's 3 PER person, that means 3 will have a variable: 3x

Let X be the random variable representing the number of calls received in an hour by a 911 emergency service. A portion of the p
ivolga24 [154]

For any distribution, the sum of the probabilities of all possible outcomes must be 1. In this case, we have to have

P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)=1

We're told that p=P(X=1)=P(X=2), and we're given other probabilities, so we have

0.25+2p+0.10+0.05=1\implies2p=0.6\implies p=0.3

The expected number of calls would be

E[X]=\displaystyle\sum_xx\,P(X=x)

E[X]=0\,P(X=0)+1\,P(X=1)+\cdots+4\,P(X=4)

E[X]=1.4

what is the hight of a cylinder with a volume of 384tt cubic inches and a radius of 8 inches? round to the nearest tenth of an i
skelet666 [1.2K]

Answer:

1.9 inches

Step-by-step explanation:

We need to utilise one important formula in this question which is the volume of a cylinder formula. We need to work out the height of the cylinder given the following information that the radius is 8 inches and the volume is 384 cubic inches. We can set up an equation to find the value of the height so,

→ π × r² × h = 384

⇒ Substitute in 8 for 'r'

→ π × 8² × h = 384

⇒ Simplify

→ π × 64 × h = 384

⇒ Divide both sides by 64 to isolate π and h

→ π × h = 6

⇒ Divide both sides by π to isolate 'h' and find the value of the height

→ h = 1.9098593171

The height of a cylinder with a volume of 384 cubic inches and a radius of 8 inches is 1.9 inches

vekshin1

Answer:

B

Step-by-step explanation:

For each box, there is 1 defective lightbulb. Therefore, a delivery of 4 boxes will have 4 defective lightbulbs. A delivery of 2 boxes has 2 defective lightbulbs. 4 defective lightbulbs subtracted by 2 defective lightbulbs equals 2 more defective lightbulbs in 4 boxes than 2. Therefore, it is B.
