If you add 1 to me and multiply me by 2, you get 24. What number am I?

First we turn the 17.2 km into mm. To do that we turn it into 17,200 m then into 1,720,000 cm then into 17,200,000 mm. Then we just divide 17.2 million by 86 so 17,200,000÷86=200,000. so we know that the scale of the map is 1:200,000. Also pls mark as brainliest answer thx.

The numbers can be a solution for the inequality 32+a>44 is 13 and 14.

If the equation or inequality have variable terms, than there might be some values of those variables for which the equation or inequality might be correct. Such values are known as solution to that equation or inequality. To set of such values are called solution set to be considered equation or inequality.

Given that;

The inequality= 32+a>44

To solve the inequality 32 + a > 44, we need to isolate the variable "a" on one side of the inequality.

32 + a > 44

Subtract 32 from both sides:

a > 44 - 32

a > 12

This means that any number greater than 12 can be a solution to the inequality.

Therefore, the inequalities numbers 13 and 14 can be solutions, but 11 and 12 cannot.

Answer:

3.643 × 10-1

Step-by-step explanation:

The equation that describes the value of the car as a function of time in 4-year periods is: V = 28,250e^(-0.056t)

To write the equation that describes this relationship, we first need to find the initial value and the depreciation rate.

The initial value of the car is $28,250, which means

when t = 0, V = 28,250.

We can use this information to find the depreciation rate, r, by using the formula:

V = V₀e^(rt)

When t = 4, V = 22,600.

Plugging these values into the equation above, we get:

22,600 = 28,250e^(4r)

Dividing both sides by 28,250 and taking the natural logarithm of both sides, we get:

4r = ln(22,600/28,250)

Simplifying, we get:

r ≈ -0.056

So, the equation that describes the value is: V = 28,250e^(-0.056t)

Hello!

This is because you already have a solution for a variable, y, and you can simply plug in the value of y for the second equation

The same thing as above, you already have the value of y, and you can simply plug it into the second equation.

You should use elimination because you can simply eliminate the variable y by adding the two equations, as they have the same coefficient of 3.

Same as above, simply add the two equations to eliminate x, because they have the same coefficients of 7.

You have the value for y, so simply plug it into the other equation to solve for x.

You have -2x in both equations, and subtracting the equations will eliminate the variable x, and you can then solve for y.

Subtracting 1 from -1 does not equal 2.

When you subtract 1 from -1, you're essentially calculating -1 - 1, which results in -2.

To clarify, subtraction is an arithmetic operation where you take away a number from another number to find the difference between them. In this case, subtracting 1 from -1 gives you a result of -2, not 2.

Answer:

1- (-1 = 2

1 + 1 = 2

Step-by-step explanation:

when there is subtract after 1 we have to put bracket then again subtract we cannot write subtract two times we have two put bracket and when there is bracket we have to multiply - and - and minus minus is plus thus 1 + 1 = 2

Answer:

0.1056 = 10.56% probability that their average salary is more than $77,500.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean $75,000 and standard deviation $8,000.

This means that \(\mu = 75000, \sigma = 8000\)

Sample of 16

This means that \(n = 16, s = \frac{8000}{\sqrt{16}} = 2000\)

What is the probability that their average salary is more than $77,500?

This is 1 subtracted by the pvalue of Z when X = 77500. So

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem

\(Z = \frac{X - \mu}{s}\)

\(Z = \frac{77500 - 75000}{2000}\)

\(Z = 1.25\)

\(Z = 1.25\) has a pvalue of 0.8944

1 - 0.8944 = 0.1056

0.1056 = 10.56% probability that their average salary is more than $77,500.

Answer:

$70 spent altogether

Step-by-step explanation:

Since $20 is what Alex had left after spending 2/3 of the remainder, 20 must be 1/3 of the remainder, meaning the remainder would be 20 x 3, or $60 (and $40 was spent). As Alex had spent 1/3 of the pocket money and $60 was what was left after spending that, $60 must be 2/3 of the pocket money. We can divide 60 by 2, which gives $30, or 1/3 of the original as what he spent. $40 plus $30 is $70, so Alex spent $70 altogether.
