Answer:

Ella should not have included 5 in absolute value portion of the equation

Step-by-step explanation:

Because -1 is a negative number in order to find the true distance between A and B you have to make it positive.

But, because Ella included 5 in the absolute value portion of the equation it messed up the answer.

Factor the polynomial by its greatest common monomial factor.
inna [77]

Answer:

5 {y}^{2} (4 {y}^{4}  - 3 {y}^{2}  + 8)

Step-by-step explanation:

We want to factor the common monomial out of :

20 {y}^{6}  - 15 {y}^{4}  + 40 {y}^{2}

The greatest common monomial fact is

5 {y}^{2}

We factor to get:

5 {y}^{2} (4 {y}^{4}  - 3 {y}^{2}  + 8)

The expression in the parenthesis has no common factor again since we factored the greatest common factor.

There are 15 rolls of film in a box and 3 are defective. Two rolls are to be selected, one after the other. What is the probabil
dem82 [27]
<h2>Answer:</h2><h2>The probability of selecting a defective roll followed by another defective roll = \frac{1}{35}</h2>

Step-by-step explanation:

The total number of rolls in a box = 15

The number of defective items = 3

Two rolls are to be selected, one after the other. The probability of selecting a defective roll followed by another defective roll = ?

The probability that the first roll is detective = \frac{3}{15}

The probability that the second roll is detective = \frac{2}{14}

Required probability = (\frac{3}{15} ) (\frac{2}{14} )

= \frac{1}{35}

For a class project, Henry needs to know how many students at M College think that
grandymaker [24]

The estimated number of students at the M College who agree climate change is a serious issue is  1759

The percentage of total students is 59.42%

The method used can be biased.

<h3>How many students believe climate change is a serious issue?</h3>

The students surveyed are the sample while the students in the M College are the population. A population is the party of interest in an experiment. A population consists of all the members of the group. A sample is a smaller group of the population.

The limitation of using a sample to estimate for the population is that the sample might be a biased estimate of the population. If the sample is biased, the result of the experiment would be inaccurate.

Estimated number of students at M College = (sample that agree that climate change is a serious problem / total number of people surveyed) x number of students

(205 / 345) x 2960 = 1759

Percentage = (1759 / 2960) x 100 = 59.42%
