Answer:
A) 5
Step-by-step explanation:
Distance between two points is calculated as:
Step 1: locate the coordinate points:
Point 1- (x₁ , y₂) = (-5, -2)
Point 2-(x₁ , y₂)= (-9, -5)
Formula to find distance between two points = √(x₂−x₁)² + (y₂−y₁)²
Step 2: input the values
√(−9− −5)² + (−5− −2)²
= √(−4)² + (−3)²
=√16 + 9
= √25 ........ square root of 25
= 5
Distance between points (-5, -2) and (-9, -5) is 5

The circumference of the earth is given.
Circumference of earth: 24,901 miles
What is the diameter of earth? Round your answer to the nearest tenth. Use 3.14 for π.
Answer:
7930.3 miles = d
Step-by-step explanation:
The circumference equals
C = pi *d
24901 = 3.14 d
Divide each side by 3.14
24901 / 3.14 = d
7930.254777 = d
Rounding to the nearest tenth
7930.3 =d
An automobile salesman receives a monthly bonus check if his commission income is at least $7,700.00 in a given month. There are 48 automobiles on the lot for sale and he receives a commission of $700.00 per sale. Which inequality shows the number of automobiles,x , the salesman must sell in order for him to receive a bonus check at the end of the month?
Answer:
The inequality that represents the number of cars he needs to sell is: [tex]x \geq 11[/tex]
Step-by-step explanation:
The commission received by the salesman, can be modeled by the following expression:
[tex]\text{commission}(x) = 700*x[/tex]
Where "x" is the number of sold cars. Since he needs to achieve a commission value of at least 7700, then the inequality that represents the number of cars he needs to sell is:
[tex]700*x \geq 7700[/tex]
We can solve for "x" in order to find the number of cars he needs to sell:
[tex]x \geq \frac{7700}{700}\\\\x \geq 11[/tex]
He needs to sell at least 11 cars.
Which angle in ADEF has the largest measure?
Answer:
F is the largest angle
Step-by-step explanation:
The largest angle is opposite the largest side. The smallest angle is opposite the smallest side.
The largest side is 4 so the largest angle is F
equation of a straight line (see attached)
Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2,3)
m = [tex]\frac{3-7}{2-4}[/tex] = [tex]\frac{-4}{-2}[/tex] = 2 , thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 3), then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 2x - 1 ← equation of line
One serving of a cereal is 3/4 cup. Each box of cereal has about 9 cups of cereal and costs $3.80. Is the price per serving greater than $0.50? Complete the explanation.
Answer:
The price per serving is $0.315, therefore, it's less than $0.5
Step-by-step explanation:
In order to calculate the price per serving, we can first calculate the price per cup, this is done by dividing the total value of the box by the number of cups it can serve:
[tex]price_{cup} = \frac{3.8}{9} = 0.42[/tex]
Since each serving is [tex]\frac{3}{4}[/tex] of a cup, then it's price has the same proportion and is given by:
[tex]price_{serving} = \frac{3}{4}*0.42 = 0.315[/tex]
The price per serving is $0.315, therefore, it's less than $0.5

Answer:
D
Step-by-step explanation:
Since the interior angles of a triangle will always add up to 180 degrees, angle B must equal 180-67-40=73 degrees, meaning that angle B corresponds to angle E in the other triangle. A corresponds to D, and F maps to C. Since no rotation is necessary, all you need to do is align two of the vertices to their corresponding vertice on the other triangle. The only answer choice here that does this is choice D, meaning that it is the correct answer. Hope this helps!

Before graduating this year, a senior homeroom was given a survey. Of those surveyed, 24% felt they learned better at home. Of this group, 80% said they plan on taking an online course in college. Of the students who felt they did not learn better at home, 40% said they plan on taking an online course in college
Part A
What is the probability a person who does not plan on taking an online course felt they learned better at home?
A : 2/21
B : 24/125
C : 38/125
D : 19/31
E :None of these
Part B
What is the probability a person who does plan on taking an online course felt they did not learn better at home?
A : 2/21
B : 24/125
C : 38/125
D : 19/31
E : None of these
Answer:
(A) The correct option is (A).
(B) The correct option is (E).
Step-by-step explanation:
The events can be defined as follows:
X = students felt they learned better at home
Y = students plan on taking an online course in college
The information provided is:
P (X) = 0.24
P (Y|X) = 0.80
P (Y|X') = 0.40
[tex]P(Y'|X)=1-P(Y|X)\\=1-0.80\\=0.20[/tex]
[tex]P(Y'|X')=1-P(Y|X')\\=1-0.40\\=0.60[/tex]
The Bayes' theorem states that the conditional probability of an event E[tex]_{i}[/tex] given that another event A has already occurred is:
[tex]P(E_{i}|A)=\frac{P(A|E_{i})P(E_{i})}{\sum {P(A|E_{i})P(E_{i})}}[/tex]
(A)
Compute the probability a person who does not plan on taking an online course felt they learned better at home as follows:
Use the Bayes' theorem.
[tex]P(X|Y')=\frac{P(Y'|X)P(X)}{P(Y'|X)P(X)+P(Y'|X')P(X')}[/tex]
[tex]=\frac{0.20\times 0.24}{(0.20\times 0.24)+(0.60\times 0.76)}\\\\=0.09524\\\\\approx 0.095[/tex]
Thus, the probability a person who does not plan on taking an online course felt they learned better at home is 0.095 or 2/21.
(B)
Compute the probability a person who does plan on taking an online course felt they did not learn better at home as follows:
[tex]P(X'|Y')=1-P(X|Y')\\=1-0.095\\=0.905[/tex]
Thus, the probability a person who does plan on taking an online course felt they did not learn better at home is 0.905.

What is the circumference, in centimeters, of the circle? Use 3.14 for π. Enter your answer in the box.
The diameter is 24.
Please help me, I need this now.
Answer:
75.36 cm
Step-by-step explanation:
Radius for circle is half of diameter
given diameter is 24
therefore radius = half of 24 = 24/2 = 12
circumference of circle is given by [tex]2\pi r[/tex]
where r is the radius
therefore ,circumference of circle
[tex]circumference = 2\pi r = 2*3.14*12\\\\circumference = 75.36[/tex]
Thus, circumference of circle is 75.36 cm

Please help! Correct answer only, please! I need to finish this assgnment this week! Matrix P has a dimensions of 3 X 4 and Matrix Q has the dimensions 4 X 5. Determine the dimensions of the matrix PQ if it is possible. Explain why if it is not. (refer to video part 4) Group of answer choices A. Matrix PQ would have the dimensions 3 X 4 B. Matrix PQ would have the dimensions 4 X 5 C. Matrix PQ would have the dimensions 3 X 5 D. These matrices can not be multiplied because their dimension don't align.
Answer: C
Step-by-step explanation:
Your answer is correct! When you multiply 2 matrices, the inner dimensions have to be equal. If they are equal, the resulting dimensions would be the outer dimentions.
(3×4)(4×5)
Since the inner (bolded) dimensions are the same, in this case 4×4, we know these matrices can be multiplied.
Since these matrices can be multiplied, the product will be 3×5, the underlined outer dimensions.
The standard deviation of a set of numbers is 22.2. What would the standard deviation be if each one of the numbers in the set was decreased by 4?
Answer:
There would be no change in the standard deviation if each one of the numbers in the set was decreased by 4.
Step-by-step explanation:
We are given that the standard deviation of a set of numbers is 22.2.
And we have to check that what would be the standard deviation, if each one of the numbers in the set was decreased by 4.
For concluding this, we will take a simple example;
Suppose that there are three set of numbers : 6, 8 and 10
Firstly, we will calculate the standard deviation for these numbers;
X [tex]X - \bar X[/tex] [tex](X-\bar X)^{2}[/tex]
6 6 - 8 = -2 4
8 8 - 8 = 0 0
10 10 - 8 = 2 4
8
Here, the Mean of the three numbers is given by;
Mean, [tex]\bar X[/tex] = [tex]\frac{6+8+10}{3}[/tex] = 8
Now, standard deviation formula is given by;
Standard deviation, s = [tex]\sqrt{\frac{(\sum X - \bar X)^{2} }{n-1} }[/tex]
= [tex]\sqrt{\frac{8 }{3-1} }[/tex] = 2
Now, we will decrease each of the three numbers by 4, we get ;
X [tex]X - \bar X[/tex] [tex](X-\bar X)^{2}[/tex]
2 2 - 4 = -2 4
4 4 - 4 = 0 0
6 6 - 4 = 2 4
8
Here, the Mean of the three numbers is given by;
Mean, [tex]\bar X[/tex] = [tex]\frac{2+4+6}{3}[/tex] = 4
Now, standard deviation formula is given by;
Standard deviation, s = [tex]\sqrt{\frac{(\sum X - \bar X)^{2} }{n-1} }[/tex]
= [tex]\sqrt{\frac{8 }{3-1} }[/tex] = 2
From this, we observe that even after decreasing each number by 4, the standard deviation remains same.
SO, we can conclude that if each one of the numbers in the set was decreased by 4 , the standard deviation of a set of numbers will be 22.2 only.

Simplify the function f(x) =
3x
(81)
4
Then determine the key aspects of the function.
The initial value is
The simplified base is
The domain is
The range is
Answer:
Step-by-step explanation:
This follows the form
[tex]y=a(b)^x[/tex]
where a is the initial value and b is the base with the exponent. Using that information, we can see that the initial value in our function is 1/3. Simplifying the base will take some work. Let's first rewrite this is a radical:
[tex]81^{\frac{3x}{4} }=\sqrt[4]{81^{3x} }[/tex]
Now let's break up 81 into its factors. 81 is 9*9 which is 3*3*3*3. Therefore,
[tex]81=3^4[/tex]
We will use that as a simplification:
[tex]\sqrt[4]{(3^4)^{3x}}[/tex] which simplifies to
[tex]\sqrt[4]{3^{12x}}[/tex]
Rewriting that as an exponent looks like this:
[tex]3^{\frac{12x}{4}}[/tex] which simplifies to
[tex]3^{3x}[/tex]
That's the answer for the second part. The whole exponential equation now is
[tex]f(x)=\frac{1}{3}(3)^{3x}[/tex]
The domain for an exponential function is all real numbers and the range is

Ruben and Victor both track the number of miles they walk each day for 6 months. The data is normally distributed for each student.
Ruben had a mean μR of 5 miles with a standard deviation σR=1.1.
Victor had a mean μV of 4.4 miles with a standard deviation σV=1.4.
What are the probabilities that Ruben walked more than 6.1 miles and that Victor walked less than 5.8 miles? Select the probabilities that apply.
16%
34%
68%
545
95%
Answer:
Step-by-step explanation:
Let x be the random variable representing the number of miles that each person walked each day for 6 months. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
For Rueben,
µ = 5
σ = 1.1
the probability that Rueben walked more than 6.1 miles is expressed as
P(x > 6.1) = 1 - P( x ≤ 6.1)
For x = 6.1,
z = (4 - 6.1)/1.1 = - 1.91
Looking at the normal distribution table, the probability corresponding to the z score is 0.02807
P(x > 6.1) = 1 - 0.02807 = 0.97193
P(x > 6.1) = 0.97 × 100 = 97%
For Victor,
µ = 4.4
σ = 1.4
the probability that Victor walked less than 5.8 miless is expressed as
P(x < 5.8)
For x = 5.8,
z = (5.8 - 4.4)/1.4 = 1
Looking at the normal distribution table, the probability corresponding to the z score is 0.8413
P(x < 5.8) = 0.84 = 84%
