Answer:

x = 4

Step-by-step explanation:

First, you subtract 1 from both sides, giving you 3x = x + 8

Then you subtract 1x from both sides, so 2x = 8

Divide the 2 from both sides which leaves you with the answer, x = 4

Answer:

30 minutes.

Step-by-step explanation:

You can make a proportion, which would be 10 selfies : 12 minutes. The second one will be 25 selfies : x minutes.

They have to be equal, since it is given that the rate stays the same. So 10:12=25:x

A proportion can be written as a fraction, so 10/12=25/x.

Cross multiply, and you get 10*x=12*25, or 10x=300.

Now divide both sides by 10 to get x=30.

Answer:

No, because the population mean, μ, is not included within the confidence interval estimate.

Step-by-step explanation:

A (1 - α)% confidence interval for a population parameter can be used make inferences about a statistic test of the parameter.

Decision rule:

If the null value of the population parameter is included in the interval then the null hypothesis will not be rejected. And vice-versa.

In this case, a market researcher wants to determine whether the population mean​ time customers spent on that website is 13 minutes a day or not.

The hypothesis can be defined as follows:

H₀: The population mean​ time customers spent on that website is 13 minutes a day, i.e. μ = 13.

Hₐ: The population mean​ time customers spent on that website is different from 13 minutes a day, i.e. μ ≠ 13.

The 95% confidence interval that the mean​ time customers spent on​ that website per day is, (15, 50).

The 95% confidence interval for the population mean time does no consist of the null value. Thus, the null hypothesis will be rejected.

It can be concluded that the population mean​ time customers spent on that website is not 13 minutes. Since the 95% confidence interval consist of values more than 13 minutes, it can be said that the  mean​ time customers spent on that website is more than 13 minutes.

Thus, the answer is:

No, because the population mean, μ, is not included within the confidence interval estimate.

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

Given n = 5, p = 0.58, and q = 0.42.

P(0) = ₅C₀ (0.58)⁰ (0.42)⁵⁻⁰ = 0.013

P(1) = ₅C₁ (0.58)¹ (0.42)⁵⁻¹ = 0.090

P(2) = ₅C₂ (0.58)² (0.42)⁵⁻² = 0.249

P(3) = ₅C₃ (0.58)³ (0.42)⁵⁻³ = 0.344

P(4) = ₅C₄ (0.58)⁴ (0.42)⁵⁻⁴ = 0.238

P(5) = ₅C₅ (0.58)⁵ (0.42)⁵⁻⁵ = 0.066

The most likely result is 3 families.

The probability of at least 3 families is:

0.344 + 0.238 + 0.066 = 0.648

Answer:

-11

Step-by-step explanation:

Mean of a given set of data = Sum of all observations ÷ Total number of observations

Mean of this data set = 88 + 82 + 97 + 76 + 79 + 92 + 65 + 84 + 79 + 90 + 75 + 82 + 78 + 77 + 93 + 88 + 95 + 73 + 69 89 + 93 + 78 + 60 + 95 + 88 + 72 + 80 + 94 + 88 + 74

Mean = 2729 ÷ 30

Median = the middle observation in a given set of data

Median of these test scores = 60 , 65 , 69 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 78 , 79 , 79 , 80 , 82 , 82 , 84 , 88 , 88 , 88 , 88 , 89 , 90 , 92 , 93 , 93 , 94 , 95 , 95 , 97 .

Median = 82 + 82 / 2

= 164 ÷ 2

= 82

Mode = most frequently occurring number in a given set of data .

Mode of these test scores =

= 60 = 1 time

= 65 = 1 time

= 69 = 1 time

= 72 = 1 time

= 73 = 1 time

= 74 = 1 time

= 75 = 1 time

= 76 = 1 time

= 77 = 1 time

= 78 = 2 times

= 79 = 2 times

= 80 = 1 time

= 82 = 2 times

= 84 = 1 time

= 88 = 4 times

= 89 = 1 time

= 90 = 1 time

= 92 = 1 time

= 93 = 2 times

= 94 = 1 time

= 95 = 2 times

= 97 = 1 time

Midrange = average of the largest and smallest number in a given set of data

Midrange of these test scores = 97 + 60 / 2

= 97 + 60 / 2

= 157 ÷ 2

= 78.5

Therefore , the correct option is :-

8.1% is the exact interest rate

The exact rate of interest is 8.11%.

The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.

Given:

Arianna North borrowed $12,500

She agreed to pay back $13,250 in 270 days.

let x be the interest rate was she paying

x= 13250 - 12500

= 750

So, x= 750/ 12500 (270/ 365)

x% = 750/ 9,246.57

x% = 0.0811

x%= 8.11%

Hence, the exact rate of interest is 8.11%.

Answer:

Find the Equation of a Line Given That You Know a Point on the Line And Its Slope. The equation of a line is typically written as y=mx+b where m is the slope and b is the y intercept.

Step-by-step explanation:

Step 1: Calculate

We calculate the square root of 23 to be:

√23 = 4.79583152331272

Step 2: Reduce

Reduce the tail of the answer above to two numbers after the decimal point:

4.79

Step 3: Round

Round 4.79 so you only have one digit after the decimal point to get the answer:

4.8

To check that the answer is correct, use your calculator to confirm that 4.82 is about 23.

The square root of the number 23 is 4.8 after using the division method the answer is 23.

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that:

The number is 23 which is a real number and positive number.

As we know we can find the square root of a positive numbers only, the square root of a nagative number cannot exist

The square root of the number 23 = √23

The sign √ is a radical sign.

After using the division method;

√23 = 4.7958

After reducing the number up to two decimal places:

= 4.79

Rounding the above number to the tenth:

= 4.79 ≈ 4.8

4.8x4.8 = 23.04 ≈ 23

Thus, the square root of the number 23 is 4.8 after using the division method the answer is 23.

Answer:

x = 15

Step-by-step explanation:

The definition of alternate interior angles means that both of these labeled angles will be equal. Therefore, 60 = (3x + 15)

60 = 3x + 15

Divide this by 3 on both sides

20 = x + 5

Subtract 5 from both sides

15 = x or x = 15

Answer:n=9

Step-by-step explanation:

Answer:

This is because it is easier this way.

You avoid the problem of putting an element in one set and then realizing that the element also belongs to another set, then you must erase something in order to put the element in both sets. Starting with the intersection allows you to know where will be each set in the diagram, and in this way, the diagram should end up being more readable or "clean".

This may seem small, but being "clean" when doing math, will allow you to have an easier time dealing with a lot of problems. And also will be easier for other people when reading your equations and such.

Answer:

x3 + x4 ≤ 1

Step-by-step explanation:

Upgrades considered = wood floors, Kitchen tile, New back door and a repaired garage

The constraint of whether to upgrade the kitchen either by the landlord or by  a contractor can be represented with the scheme below:

x3 + x4 ≤ 1

The constraint is written this way because  only one scheme can be used at a time i.e when x3 = 1 , x4 = 0 and vice versa. also

note that both x3 and x4 can be = 0.  because the upgrade of the kitchen tiles is under probability and the landlord might decide not to upgrade the kitchen tiles hence both schemes ( x3 and x4 ) can be = 0
