Anna takes 10 selfies every 12 minutes at this rate how many minutes for 25 selfie’s
Answers
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.

Answers
Answer:
The correct answer is - option D. There is little or no evidence of a linear association because the absolute value of r is less than the critical value.
Step-by-step explanation:
Given:
Age Cholesterol
49 55
27 45
52 40
38 57
44 28
The linear correlation coefficient between age and HDL cholesterol can be computed by the=
r = Cov (X, Y)/ δx.δy
=v∑XY /√∑X2. ∑Y2
rv= negative 0.192
The absolute value of r is less than the critical value so there is no or very little evidence of linear association.

Assume you have applied for two scholarships, a Merit scholarship (M) and an Athletic scholarship (A). The probability that you receive an Athletic scholarship is 0.18. The probability of receiving both scholarships is 0.11. The probability of getting at least one of the scholarships is 0.3. Let M denote the event that you will receive a Merit scholarship. Let A denote the event that you will receive an Athletic scholarship. Answer questions 11-15. What is the probability that you will receive a Merit scholarship
Answers
Answer:
The probability of obtaining a Merit Scholarship = 0.23
Step-by-step explanation:
From the given information:
The probability of obtaining a merit scholarship P(A) = 0.18
The probability of obtaining both P(A ∩ M) = 0.11
The probability of getting at least one P(A ∪ M) = 0.3
The objective is to determine the probability of obtaining a Merit Scholarship.
So, as given:
if M represents Merit Scholarship and A represent Athletic Scholarship,
the probability of obtaining a Merit Scholarship is as follows;
P(M) = P(A ∪ M) + P(A ∩ M) - P(A)
P(M) = 0.3 + 0.11 - 0.18 = 0.23
P(M) = 0.23

Triangle A to B has a change of +3 in x values, but Triangle B to C has a change of +6 values so each triangle doesn’t have the same changes in x values.
Triangle A to B has a change of +2 in y values, Triangle B to C has a change of +4 values so each triangle doesn’t have same change in values.
Triangle A to B change in y over change in x = 2/3, Triangle B to C change in y over change in x = 4/6, both have decimal values of 0.66. Therefore, each triangles has the same ratio of change in y over change in x.

Answers
Answer:
40 m/s/s.
Step-by-step explanation:
Acceleration = velocity / time
= 200 / 5
= 40 m/s/s.
Answer:
a = 40m\s^2
Step-by-step explanation:
acceleration is the change of velocity in a certain time interval, which means that it is equal to ( V final - V initial ) \ t
so acceleration here is ( 200 - 0 ) \ 5
which is equal to: 40 m\s^2 and that means that the racer is speeding up by 40 meters each second

square root of 23 to the nearest tenth
Answers
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.
What is a number?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.

she paying? (Round your answer to the nearest tenth of a percent.)
Answers
8.1% is the exact interest rate
The exact rate of interest is 8.11%.
What is rate of interest?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%.

A market researcher collects a simple random sample of customers from a population of over a million customers that use a home improvement website. After analyzing the sample, she states that she has 95% confidence that the mean time customers spent on that website per day is between and minutes. Suppose that the population mean time customers spent on that website is minutes a day. Does this value of the population mean help to show that the confidence interval estimate is correct? Explain.
Answers
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.

Answer:
B. he didn't combine -3 and -9 correctly
The error that Austin made in his work is Austin did not combine -3 and -9 correctly.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that solved the equation -3 + 7x - 9 + 8x = 54 as shown below.
-3 + 7x - 9 + 8x = 54
15x - 6 = 54
15x = 60
x = 4
We need to check where did Austins has done wrong.
-3 + 7x - 9 + 8x = 54
15x-12=54

A landlord is considering upgrades and repairs, including wood floors, kitchen tile, a new back door, and a repaired garage door. The landlord could do these things himself or hire a contractor. The contractor could finish the job in half the time but would charge more. The landlord wants to leave the choice of whether to actually upgrade the kitchen tile up to the optimization algorithm. How should this constraint be written if he uses the following scheme for decision variables? x1 = contractor works on wood floors x2 = landlord works on wood floors x3 = contractor works on kitchen tile x4 = landlord works on kitchen tile x5 = contractor works on back door x6 = landlord works on back door x7 = contractor works on garage door x8 = landlord works on garage door Group of answer choices x3+ x4≤ 1 x3+ x4= 1 x3- x4= 1 x3- x4≤ 1
Answers
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

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