Answers

Answer 1

Answer:

x ≤ 63.4

Step-by-step explanation:

.25x+4.15 ≤20

Subtract 4.15 from each side

.25x +4.15 -4.15 ≤ 20-4.15

.25x ≤ 15.85

Divide each side by 15.85

.25x/.25 ≤ 15.85/.25

x ≤ 63.4

Each question Sandra answers incorrectly changes her overall score by - points. Sandra's

overall score was -4 points, and then she answered the last question incorrectly. What

was Sandra's final score?

Answers

Answer: -5

Step-by-step explanation:

For each question Sandra answered incorrectly her overall score was changed by -1 point.

Her overall score was -4 before she attempted her last question incorrectly. Since a wrong answer gives her -1 point and her overall is -4

We add her overall and her point from last question which sums up to -5.

So sandras final score is -5

Use the Counting Principle to find the probability.

rolling a 1 on each of 4 number cubes?

Answers

Answer:

1 / 1296

Step-by-step explanation:

Rolling a 1 for one of the cubes is 1 / 6

1 / 6 * 1 / 6 * 1 / 6 * 1 / 6 = 1 / 1296

Answer:

1 / 1296

Step-by-step explanation:

We have been given that three cubes are being rolled and we are required to find the probability of getting 4 on 1 cubes.

We know the probability of rolling a 4 on one cube will be .  the probability of rolling 4 in each of the individual cubes will be .

But we want 4 to be rolled on 1 cubes at once, in order for that to happen, we need to get a four on first cube AND second cube AND third cube. Since there is AND between the events, we will multiplied their probabilities as per counting principle. Thus, the required probability of rolling 4 on each of the 1 cube is  which simplifies to . 1 / 1296

degrees in the next six hours, what will the temperature be in six

Answers

Answer:

-7 degrees

Step-by-step explanation:

Dropping 12 degrees means that it will get colder by 12 degrees. The colder it gets, the lower the temperature. 5 degrees - the current temperature, is going to be dropped by 12 degrees. To calculate this: 5-12 = -7 (degrees)

A 10 ft long ladder has one end that leans against a wall and another that rests on the ground 6 feet from the wall. To find out how high on the wall the ladder rests, which of the following formulas would be used?
Distance Formula

None of these choices are correct.

Answers

Answer:

Pythagorean Theorem

Step-by-step explanation:

A 10 ft long ladder has one end that leans against a wall and another that rests on the ground  - hypotenuse

6 feet from the wall - one leg

how high on the wall the ladder rests - second leg.

We have a right triangle, we need to find a leg,

​

Answers

15 pots

Step by step explanation

....

We can have the following cases:

5 pots and each pot has 15 seeds.

3 pots and each pot has 25 seeds.

15 pots and each pot has 5 seeds.

What are factors of a number?

Factors are the numbers that divides another number with no remainder.

Given,

Davi has 75 flower seeds.
Every seed is planted.

Every pot has the same number of seeds.

Find the number of pots.

We have,

Total seeds = 75

Since every seed must be planted we can have the following cases.

Case1 - 5 x 15

Here there are 5 pots and each pot has 15 seeds

Case2 - 3 x 25

Here there are 3 pots and each pot has 25 seeds.

Case3 - 15 x 5

Here there are 15 pots and each pot has 5 seeds.

Thus we can have the following answer:

5 pots and each pot has 15 seeds.

3 pots and each pot has 25 seeds.

15 pots and each pot has 5 seeds.

Two histograms showing the number of pets owned by boys and girls in a science class are each skewed left. Which measure of variability should be used to describe the data? mean median standard deviation interquartile range

Answers

Answer: D : interquartile range

Step-by-step explanation: I just took the test

The measure of variability which should be used in this case interquartile range. so option D is correct.

What is quartile ?

A quartile is a type of quantile that divides a data set into four equal parts, or quarters. The first quartile (Q1) marks the 25th percentile of the data, the second quartile (Q2) marks the 50th percentile, or median, of the data, and the third quartile (Q3) marks the 75th percentile of the data. These quartiles divide the data into four equal parts and provide information about the distribution of the data and its spread. The interquartile range (IQR), which is the difference between Q3 and Q1, is a measure of the spread of the middle 50% of the data.

When the data is skewed, the mean can be misleading as it is affected by the skewness of the data. In such cases, the median is a better measure of central tendency that represents the typical value of the data.

Therefore, the measure of variability that should be used to describe the data in this case is the interquartile range (IQR). IQR is a measure of spread that is not affected by extreme values or outliers and is often used with skewed data. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1) of the data.

So, the answer is the interquartile range.

Answer:

-32

Step-by-step explanation:

Look at the attachment

Functions can be represented as equations and graphs.

The value of [tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)}[/tex] is -32

From the graph, we have the following values.

[tex]\mathbf{f(0)= 1}[/tex]

[tex]\mathbf{g(-8)= -6}[/tex]

So, we have:

[tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)= -8 \times 1 + 4 \times -6}[/tex]

Simplify

[tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)= -8 -24 }[/tex]

[tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)= -32 }[/tex]

Hence, the value of [tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)}[/tex] is -32
