Given a ⊥ c and b ⊥ c, what can you say about a and b?
A. a ⊥ b, because if two lines are perpendicular to the same line, then they are perpendicular to each other.
B. a and b form a straight line, because if two lines are perpendicular to the same line, then they form a straight line.
C. a and b are intersecting lines because if two lines are perpendicular to the same line, then they are intersecting lines.
D. a || b, because if two lines are perpendicular to the same line, then they are parallel to each other.
Answer:
Answer is B.
Step-by-step explanation:
C is the middle line and A is on one side and B is on the other.

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.
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.
approximate
square root of 23 to the nearest tenth
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.

What is 9/10 divided by 3/4?
Answer:
6/5
Step-by-step explanation:
hi! when dividing fractions, we use the KCF rule, which stands for keep,change,flip. we keep the first fraction the same, change the division symbol to multiplication, and flip the second fraction to its reciprocal. therefore, we now have:
9/10 * 4/3
now, we can multiply the numerators and denominators.
36/30
we can simplify this.

3. Austin solved the equation as shown below. Which describes the error
that Austin made in his work?
Austin's Work:
-3 + 7x - 9 + 8x = 54
15x - 6 = 54
15x = 60
x = 4
A. Austin did not combine 7x and 8x correctly.
B. Austin did not combine -3 and -9 correctly.
C. Austin did not divide correctly
D. Austin did not make an error in his work.
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
For Austin while combining -3 and -9 he got -6 which is wrong.
So Austin did not combine -3 and -9 correctly.
Hence, the error that Austin made in his work is Austin did not combine -3 and -9 correctly.

Write a quadratic function f whose zeros are 8 and -3.
Answer:
f(x) = x² - 5x - 24
Step-by-step explanation:
Step 1: Define
Roots/zeros = 8, -3
Step 2: Rewrite
x = 8, -3
Step 3: Write quadratic function
Set zeros into factored binomials: (x + 3)(x - 8)Expand: x² - 8x + 3x - 24Combine like terms: x² - 5x - 24Answer:
f(x) = x^2 - 5x - 24.
Step-by-step explanation:
In factor form that would be:
f(x) = (x - 8)(x + 3)
f(x) = x(x + 3) - 8(x + 3)
= x^2 + 3x - 8x - 24
f(x) = x^2 - 5x - 24.
please help measure
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

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
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

Does a linear relation exist between age and HDL cholesterol? A. There appears to be a positive linear association because r is positive and greater than the critical value. B. There is little or no evidence of a linear association because r is positive and greater than the critical value. C. There appears to be a negative linear association because r is negative and less than the negative critical value. D. There is little or no evidence of a linear association because the absolute value of r is less than the critical value. More
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.

A drag racer accelerated from 0 m/s to 200 m/s in 5 s.what was the acceleration
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
