A insurance office keeps track of the number of car insurance claims filed each day. Based on the data collected, it determines

Ivenika [448]

Answer:

The expected number of new claims filed each day is 1.8.

Step-by-step explanation:

We are given the following probability distribution:

$P(X = 0) = 0.25$

$P(X = 1) = 0.15$

$P(X = 2) = 0.25$

$P(X = 3) = 0.25$

$P(X = 4) = 0.1$

a. What is the expected number of new claims filed each day

Multiplication of each outcome by its probability, so:

$E(X) = 0*0.25 + 1*0.15 + 2*0.25 + 3*0.25 + 4*0.1 = 1.8$

The expected number of new claims filed each day is 1.8.

Set each factor equal to 0:
$x^{2} +4=0$ or $x^{2} -36=0$
$x^{2} =-4$ $x^{2} =36$
x = +/- 2i x = +/- 6

Roughly 75% of students take the bus to school. If you were to ask 9 students in your class, what is the probability that at mos

GREYUIT [131]

The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%

<h3>How to find the probability?</h3>

We know that roughly 75% of the students take the bus, then, if we select a student at random.

There is a probability of 0.75 that the student takes the bus.
There is a probability of 0.25 that the student does not take the bus.

The probability that at most 8 out of 9 students take the bus, is equal to one minus the probability of the 9 taking the bus, which is:

p = (0.75)^9 = 0.075

Then we have:

P = 1 - 0.075 = 0.925

The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%

13.At the Finch School bake sale, donuts sell

aliina [53]

Answer:

c)

Step-by-step explanation:

create a system of equations:

d + m = 104

2d + 3m = 243

now use substitution method based on 'd = 104 - m'

2(104 - m) + 3m = 243

208 - 2m + 3m = 243

208 + m = 243

m = 35

So, 35 muffins and 69 donuts were sold.

This is 34 more donuts than muffins.
