Any value of x that is less than or equal to -2 will make the inequality true.

What is Number line?

A number line is a picture of a graduated straight line that serves as a visual representation of real numbers in primary mathematics. Every point on a number line is presumed to be a real number, and every real number is assumed to be a point.

To solve the inequality 3x - 1 <= -7, we can start by adding 1 to both sides to isolate the variable:

3x - 1 + 1 <= -7 + 1

Simplifying, we get:

3x <= -6

Next, we can divide both sides by 3 to solve for x:

3x/3 <= -6/3

Simplifying, we get:

x <= -2

This tells us that any value of x that is less than or equal to -2 will make the inequality true. We can represent this on a number line by shading all values less than or equal to -2

The circle at -2 indicates that -2 is included in the solution set, and the arrow pointing to the left indicates that all values less than -2 are also included in the solution set. Therefore, the number line that shows all of the values of x that make the inequality 3x - 1 <= -7 true is the one with all values less than or equal to -2 shaded.

At the level of significance of 0.05, the null hypothesis is not rejected and there is no convincing evidence to suggest the true proportion of television viewers who watch the show is less than 0.20. Hence, option a. is the accurate answer.

The p-value is the probability of observing a test statistic as extreme or more extreme than the one observed, assuming the null hypothesis is true. In this case, the null hypothesis is that the proportion of viewers who watch a particular show is equal to or greater than 0.20, and the alternative hypothesis is that the proportion is less than 0.20.

Since the p-value (0.47) is greater than the level of significance (0.05), we fail to reject the null hypothesis. This means that there is not enough evidence to support the claim that the proportion of viewers who watch the show is less than 0.20.

Therefore, we can conclude that at the level of significance of 0.05, the null hypothesis is not rejected. Also, there is no convincing evidence to suggest the true proportion of television viewers who watch the show is less than 0.20.

The bakery made 384 donuts and 216 bagels

A bakery is a business that produces and sells baked goods, such as bread, cakes, pastries, and cookies.

Let's use the variable "x" to represent the number of bagels made.

From the problem, we know that:

The number of donuts made is 384 more than the number of bagels made, so the number of donuts is x + 384.

The bakery made 216 bagels.

We also know that the bakery made a total of 600 donuts. So, we can set up an equation to represent the total number of pastries made:

x + 384 + 216 = 600

Simplifying and solving for x:

x + 600 = 600

x = 600 - 600 + 384

x = 384

So, the bakery made 384 + 216 = 600 pastries in total.

Therefore, the bakery made 384 donuts and 216 bagels.

The correct answer is "the more accurately the scores are represented by the mean."

The variability or dispersion of a set of scores refers to how spread out the scores are from the central tendency, which is usually measured by the mean, median, or mode.

When a set of scores has low variability or dispersion, it means that the scores are clustered closely together around the mean, and therefore, the mean is a more accurate representation of the typical score in the set.

On the other hand, when a set of scores has high variability or dispersion, it means that the scores are more spread out from the mean, and therefore, the mean may not be a very accurate representation of the typical score in the set. In such cases, other measures of central tendency, such as the median or mode, may provide a more accurate representation of the scores.

Ken total annual income is $ 55,401.98.

What has compounded annually?

The interest charged on a loan or deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest. The main distinction between compound and simple interest is this.

The completely randomized design, in which participants are assigned to treatment groups at random, is the most basic type of experimental design. The main benefit of using this method is that it minimizes the influence of chance and eliminates bias. This approach makes use of probability theory, which gives statistical analysis a strong foundation.

Given that Roth IRA has a present value of $524,856.00. The rate of interest is 3.4% per annum.

A = P(1+r)^t

A = amount

P = principal

r = rate of interest

t = time

The amount after 15 years is

A = 524,856.00(1+3.4%)¹⁵

A = 866658.9925

The total interest is  866658.9925 - 524,856.00 = $341802.99

The average interest per annum is (341802.99 /15) =22786.866

The annual income is 22786.866 + 32,615.12 = 55,401.986

Hey there! Johnny Sins always here to help,

To find out what score Natasha needs to earn on her next test, we can use the following formula:

Average = (sum of all scores) / number of scores

Let's call the score Natasha needs to earn on her next test "x".

Her average so far is:

Average = (94 + 89 + 88 + 92 + 85) / 5 = 90

Her average after her next test will be:

Average = (94 + 89 + 88 + 92 + 85 + x) / 6

Now, we need to set this equal to 90% and solve for x:

90 = (94 + 89 + 88 + 92 + 85 + x) / 6

90 * 6 = (94 + 89 + 88 + 92 + 85 + x)

540 = (94 + 89 + 88 + 92 + 85 + x)

x = 540 - (94 + 89 + 88 + 92 + 85)

x = 540 - 448

x = 92

So, Natasha needs to earn a 92% on her next test to average at least 90%.

Ten pounds of chopped walnuts would total cost $30.00. That is because 3/4 pound of chopped walnuts costs $3.75, and 10 pounds would be 13.33 times as much.

1. 3/4 pound of chopped walnuts costs $3.75

2. 1 pound of chopped walnuts costs $5.00 (3.75 x 1.33)

3. 10 pounds of chopped walnuts costs $50.00 (5.00 x 10)

To calculate the cost of 10 pounds of chopped walnuts, we need to first calculate the cost of 1 pound of chopped walnuts. We know that 3/4 of a pound of chopped walnuts costs $3.75. To calculate the cost of 1 pound, we can multiply 3.75 by 1.33, which gives us the result of $5.00. We then multiply $5.00 by 10, which gives us the result of $50.00. Therefore, 10 pounds of chopped walnuts would cost $50.00. This is because 3/4 pound of chopped walnuts costs $3.75, and 10 pounds would be 13.33 times as much.

Step-by-step explanation:

Step-by-step explanation:

x + 3y + 2z = 8

3x + y + 3z = -10

-2x - 2y - z = 10

we solve this by eliminating variables or expressing sine variables by others, and then solve for the remaining one. with that value we then cancer back to solve for the other variables.

in our case the easiest way is the elimination via combinations of equations.

let's first multiply equating 1 by -3 and then add that to equation 2 :

-3x - 9y - 6z = -24

3x + y + 3z = -10

----------------------------

0 - 8y - 3z = -34

8y + 3z = 34

then multiply equation 1 by 2 and add it to equation 3 :

2x + 6y + 4z = 16

-2x - 2y - z = 10

--------------------------

0 4y + 3z = 26

now we subtract this result from the previous result :

8y + 3z = 34

- 4y + 3z = 26

----------------------------

4y 0 = 8

y = 8/4 = 2

4×2 + 3z = 26

3z = 18

z = 18/3 = 6

x + 3×2 + 2×6 = 8

x = -10

so,

x = -10

y = 2

z = 6
