What value of k makes the equation true?

k – 3(k + 5) – 0.5 = 3(0.25k + 4)

Answers

Answer:

k = - 10

Step-by-step explanation:

k - 3(k + 5) - 0.5 = 3(0.25k + 4) ← distribute parenthesis on both sides

k - 3k - 15 - 0.5 = 0.75k + 12

- 2k - 15.5 = 0.75k + 12 ( subtract 0.75k from both sides )

- 2.75k - 15.5 = 12 ( add 15.5 to both sides )

- 2.75k = 27.5 ( divide both sides by - 2.75 )

k = - 10

For this question it has to be k = -10

What is the IQR of the following Data Set:
1, 3, 4, 5, 5, 7, 9

Answers

Hi there!

We can begin by splitting the data into two equal parts, ignoring the median.

The median is simply the number in the middle of the data, or 5.

Now, we can split the data, taking the three left numbers and the three right numbers.

We have:
Left: 1, 3, 4

Right: 5, 7, 9

Find the medians of these sections. These are the middle numbers again, so:
Left: 3

Right: 7

These are our 1st and 3rd quartiles, respectively. The IQR is the difference between these, so:
7 - 3 = 4 = IQR.

The radius(r) is half of the diameter(d) in length --> r= d/2 ; (D)

Thus if the diameter is 3 m --> that means the radius is 1.5m (B)

Hope that helps!

The formula to finding the radius is R = diameter/2, (R= d/2)

If the diameter is 3, the formula to finding radius is d/2, 3 divided by 2 is 1.5.

About ​8% of the population of a large country is math phobic. If two people are randomly​ selected, what is the probability both are ​math phobic? What is the probability at least one is math phobic​?

Answers

Answer:

the chances both are is=.64%

the chances of only one is=15.36%

Step-by-step explanation:

8%=.08

.08x.08= .0064=.64%

1-(1-0.08)×(1-0.08)

1-.92x.92

0.1536=

15.36%

a) The probability both are math-phobic: 0.0064 or 0.64%.

b) The probability that at least one is math-phobic is 0.1536 or 15.36%.

To determine the probability that both selected people are math-phobic, we can use the multiplication rule of probability.

Since the selection is random, the probability that the second person is math-phobic is also 0.08.

To find the probability that both events occur, we multiply the individual probabilities:

Probability of both being math-phobic = 0.08 x 0.08 = 0.0064

Therefore, the probability that both selected people are math-phobic will be 0.0064 or 0.64%.

To find the probability that at least one person is math-phobic, we can use the complement rule of probability.

The probability that the first person is not math-phobic ;

1 - 0.08 = 0.92.

Similarly, the probability that the second person is not math-phobic is also 0.92.

Probability of none being math-phobic = 0.92 x 0.92 = 0.8464

Probability of at least one being math-phobic = 1 - 0.8464 = 0.1536

Therefore, the probability that at least one person is math-phobic is 0.1536 or 15.36%.

Write an expression for the
product of 4 and m.

Answers

Answer:

4m

Step-by-step explanation:

Expressions do not have equal signs,  So for the product of 2 things we just multiply them together.

4m

Answer:

4 × M = P

Explanation:

A product is the result of a multiplication expression, so in this case, We're using variables to represent numbers.

P = Product

We're multiplying 4 and M, so lets rewrite this.

4 × M

This is an incomplete expression, but what will we use for our product We can use a variable. Our variable is P. So lets complete this expression.

4 × m = p.

Or, we can put it in a less complex way.

4m.

This also is a incomplete expression, but it means 4 × m.

b- 4 times -2 meters
c- 4 times 10^2 meters
d- 4 times 10^8 meters

Answers

Answer: D!!!!!!!!!!!!!

The required reasonable measure for the earth-moon distance is 4 times 10^8 meters. Option D is correct.

Given that,
The distance from the Earth to the Moon is about a hundred times the distance from California to New York. What is a reasonable measure for the Earth-Moon distance is to be determined.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Options A, B, and C is reasonable false because all are impossible terms for the distance, earth to the moon.
Option D is reasonably correct because 4 * 10^8 seems larger as the distance from the earth to the moon is also larger.

Thus, the required reasonable measure for the earth-moon distance is 4 times 10^8 meters. Option D is correct.
