Answer:

12/100 = x/350

4200 = 100x

4200/100 = 100x/100

42 = x

350 - 42 = 308

the sale price is $308

the discount is $42

Answer:

See explanations below

Step-by-step explanation:

Given the algebraic expression 2x4– 5x3 + 4x. + 7,

a) The degree is the highest power of x in the equation, from the equation we can see that the highest power of x is 4. HEnce the degree of the equation is 4

b) The terms we have are 2x^4, -5x^3, 4x and 7. In counting, we can see that we only have 4 terms in the equation hence the number of terms is 4

c) The constant term si the term without the variable x. From the equation the only term without variable x is 7. Hence the constant term is 7

d) The number attached t x is known as its coefficient. The number besides x is 4 frim the equation. Hence the coefficient of x is 4.

e) The numerical coefficient of -5x^3 is -5 since the constant value attached to x^3 is -5

Answer: probability 0.01 %

Step-by-step explanation:

P(A) = 10% = 10/100 = 0.10

pick two people -

= P(A).P(A)

= 0.10 times 0.10

= 0.01

probability = 0.01

The probability that they both own a dog is 1/50 or 0.02.

Probability is the chance of happening an event or incident.

Given, 10% of people own dogs.

Let, there are 100 people.

Therefore, the number of people own dogs is

= 100 × 10%

= 10

If I pick two people at random, then the probability that they both own a dog is

= 2/100

= 1/50

= 0.02

Answer:

B

Step-by-step explanation:

This problem is to compare the value of the two numbers. Obviously, 0.21>0.012

Answer:

a. We are 90% sure that the mean GPA for all students at her school is between 3.14 and 3.52.

b. The length would increase.

c. The interval would be narrower.

d. The biggest potential source of bias is making the students state their grades aloud, which makes it possible that students with low grades could lie their grades, making it seem higher, and the interval biased.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

Margin of error of a confidence interval:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which z is related to the confidence level(higher the confidence level, higher z) [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

This shows that if we increase the confidence level, the margin of error gets larger and the interval gets wider, while if we increase the sample size the margin of error gets smaller and the interval gets narrower.

a. Interpret the confidence level.

We are 90% sure that the mean GPA for all students at her school is between 3.14 and 3.52.

b. Explain what would happen to the length of the interval if the confidence level were increased to 99%.

We would increase the confidence level, and the interval would get wider, that is, the length would increase.

c. How would a 90% confidence interval based on a sample of size 200 compare to the original 90% interval?

Larger sample size means that the interval would be narrower.

d. Describe one potential source of bias in Ellery's study that is not accounted for by the margin of error.

The biggest potential source of bias is making the students state their grades aloud, which makes it possible that students with low grades could lie their grades, making it seem higher, and the interval biased.

Based on the information given in the sample, it should be noted that this implies that we are 90% sure that the mean GPA for all students at the school is between 3.14 and 3.52.

Lastly, a potential source of bias in Ellery's study that is not accounted for by the margin of error is making the students state their grades aloud. This will make some of them with lower grades lie.

Answer: Assuming that event A has occurred

Step-by-step explanation:

The conditional probability of B given A can be found by​ assuming that event A has occurred, and then calculating the probability that event B will occur.

So, the correct answer is d.

The conditional probability of B given A, denoted as P(B|A), represents the probability of event B occurring given that event A has already occurred.

It is calculated by assuming that event A has occurred and then determining the probability of event B occurring under that assumption.

Mathematically, the conditional probability is calculated as:

P(B|A) = P(A and B) / P(A)

Where P(A and B) represents the probability of both events A and B occurring together, and P(A) represents the probability of event A occurring.

Therefore, option d. assumes that event A has occurred and then calculates the probability that event B will occur, which aligns with the definition of conditional probability.

Answer:

63 degrees and 27 degrees

Step-by-step explanation:

Complementary angles are when two angles add to 90 degrees.

So, we can check if these pairs add up to 90 degrees.

45 + 95 = 140

38 + 42 = 80

30 + 51 = 81

63 + 27 = 90

The only pair of angles that are complementary is 63 degrees and 27 degrees.
