Step-by-step explanation:

The mean of the discounted prices is $736.25, the median is $810, the mode is $810, and the range is $645.

To find the mean of the discounted prices, we add up all the prices and divide by the total number of prices. In this case, the mean is $736.25 because (640 + 810 + 755 + 810 + 1175 + 900 + 1080 + 530) / 8 = 736.25.

To find the median of the discounted prices, we arrange the prices in ascending order and find the middle value. Since there are 8 prices, the median is the average of the 4th and 5th values, which are $810 and $810, respectively. So, the median is $810.

To find the mode of the discounted prices, we look for the value that appears most frequently. In this case, $810 appears twice, which is more often than any other price. Therefore, the mode is $810.

To find the range of the discounted prices, we subtract the smallest price from the largest price. In this case, the range is $645 because $1175 - $530 = $645.

Answer:

73

Step-by-step explanation:

When you have a line intersecting another line, the angles produced by the intersection will be equal to 180.

This means that  (-39 + x) + 146 = 180.  Solve for x.

(-39 + x) + 146 = 180

-39 + x = 34

x = 73

Answer:

13.8 days

Step-by-step explanation:

In this case we can solve it by means of a rule of three, knowing the amount of life for 1000 grams, it must be proportional for 600 grams, like this:

grams   days

 1000     23

 600        x

x = 600 * 23/1000

x = 13.8

which means that for the 600 grams it would be an average life of 13.8 days.

We have been given 4 choices. We are asked to choose the volume that could belong to a cube with a side length that is an integer.

We know that volume of a cube is cube of each side length.

To solve our given problem, we will take cube root of each given value. The cube root of which value will be an integer that will be our correct choice.

A. [tex]s^3=18[/tex]

[tex]\sqrt[3]{s^3}=\sqrt[3]{18}[/tex]

[tex]s=2.62074[/tex]

Since cube root of 18 is not an integer, therefore, 18 is not a correct choice.

B. [tex]s^3=36[/tex]

[tex]\sqrt[3]{s^3}=\sqrt[3]{36}[/tex]

[tex]s=3.301927[/tex]

Since cube root of 36 is not an integer, therefore, 36 is not a correct choice.

C. [tex]s^3=64[/tex]

[tex]\sqrt[3]{s^3}=\sqrt[3]{64}[/tex]

[tex]s=4[/tex]

Since cube root of 64 is 4 and 4 is an integer, therefore, 64 is the correct choice.

D. [tex]s^3=100[/tex]

Answer:

3. 72 degrees

Step-by-step explanation:

We can convert the values to percentage values and since a circle is 360°, we can multiply the percentages with 360° to get the degrees. The total of day is all the the things added up:

= 13+6+7+4=30

Percent swimming:

Answer is 72 degrees

Answer:

Step-by-step explanation:

swim = 6/30=  0.2 -> 0.2*360 = 72 degree

run = 13/30= 0.433 -> 0.4333 *360 = 156 degree

lift weight = 7/30 = 0.23333 -> 0.23333 *360 = 84 degree

ride bike = 4/30 =  0.133333 -> 0.133333 *360 = 48 degree

Answer:

B. 6.3%

Step-by-step explanation:

For each time that the coin is tosse, there are only two possible outcomes. Either it comes up tails, or it does not. The probability of coming up tails on a toss is independent of any other toss. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Fair coin:

Equally as likely to come up heads or tails, so [tex]p = 0.5[/tex]

Probability that the first tails comes up on the 4th flip of the coin?

0 tails during the first three, which is P(X = 0) when n = 3.

Tails in the fourth, with probability 0.5. So

[tex]p = 0.5P(X = 0)[/tex]

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]p = 0.5P(X = 0) = 0.5*(C_{3,0}.(0.5)^{0}.(0.5)^{3}) = 0.0625[/tex]

0.0625 * 100 = 6.25%

Answer:

  B.  (-4, -8)

Step-by-step explanation:

Put -4 into the first equation where x is, then evaluate. You will find ...

  y = (1/2)(-4) -6 = -2 -6 = -8

Then the point that satisfies both equations is ...

  (x, y) = (-4, -8) . . . . matches choice B

___

You can eliminate choices A and D, because they don't have -4 for the x-value.

How many diagonals does a polygon have with 5 sides, but with 6 sides?

Answer:

a. For 5 sides= 5

b. For 6 sides= 9

Step-by-step explanation:

Remember, this is the formula to calculate the number of diagonals of a polygon;

n (n-3) / 2 where n is the sides.

Thus,

for 5 sides= 5 (5-3) /2

= 5 (2) /2 = 10/2= 5

for 6 sides= 6 (6-3) /2

= 6 (3) /2 = 18/2= 9

Answer:

∠2 = 152

Step-by-step explanation:

A straight angle should always equal 180, and that is really the key to how we answer this problem. That means that ∠1 and ∠2 are supplementary, and add up to 180°.

That means that 180-28, will give us our other angle.

Answer:

152°

Step-by-step explanation:

Angles on a straight line add up to 180°

Angle 2 + 28 = 180

Angle 2 = 180 - 28

= 152°

Answer:

B

Step-by-step explanation:

First, find the y-intercept form of the equation:

x - y = 4

x - x - y = 4 - x

-y = 4 - x

-y = -x + 4

-y/-1 = -x/-1 + 4/-1 (to get the y positive)

y = x - 4

The y-intercept is -4. This means that a y-intercept two units above 4 would be -2. Whichever line crosses the y axis at the value of -2 is the answer (line B)

Answer:

1680 ways.

Step-by-step explanation:

This question is solved using Permutation formula.

Permutation formula is given as

nPr = n! / (n -r)!

In the above question we are to find how many ways we can answer 8 multiple choice questions with 4 options(A, B,C,D)

Therefore,

n = 8 multiple choice questions

r = 4 options

nPr = n! / (n - r)!

8P4 = 8! / ( 8 - 4) !

8P4 = 8! / 4!

8P4 = (8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (4 × 3 × 2 × 1)

8P4 = 40320 / 24

8P4 = 1680 ways

Therefore, the number of ways to answer 8 multiple choice questions with 4 options (A, B, C, D) for each is 1680 ways.

Answer:

65,536 ways.

Step-by-step explanation:

The Fundamental Counting Principle states that:

"If decision M can be made m ways and decision N can be made n ways, then the two decisions can be made m⋅n ways"

Therefore, we can create a model of the eight questions by drawing eight blanks:

_ _ _ _ _ _ _ _

Then, filling in each "question" with the number of options for each, which is four:

4 4 4 4 4 4 4 4

And finally, we can multiply the fours together, which would be 4⋅4⋅4⋅4⋅4⋅4⋅4⋅4 or 4⁸, which is equal to 65,536.

Answer:

45:15=9:3=3:1

9:3=3:1

3:1 stays the same.

1:3 stays the same.

4:1 stays the same.

The simplify ratios such as 45:15 and 9:3. The simplified form of 45:15 and 9:3 is 3:1. The correct option is B.

To write the ratio 45:15 in the simplest form, you have to divide both numbers by their greatest common divisor (GCD), which in this case is 15.

So, 45 divided by 15 is 3, and 15 divided by 15 is 1, which gives us the simplified ratio of 3:1.

[tex]\frac{45}{15} = \frac{3}{1}[/tex]

For the ratio 9:3, again, we divide both numbers by their GCD, which is 3, resulting in the simplified ratio 3:1.

The ratio 3:1 is already in its simplest form.

1:3 is the simplest form and 4:1 is the simplest fraction.

Answer:

-7

Step-by-step explanation:

The two lines intersect at the point (6,10), so this point belongs to both lines. This means that if we use the value of x = 6 in the lines, we will find y = 10

So we can use this point to find the values of b and m:

y = mx + 4

10 = 6m + 4

6m = 6

m = 1

y = 3x + b

10 = 3*6 + b

b = 10 - 18 = -8

So the value of b + m is -8 + 1 = -7

After substituting the intersection point (6, 10) into both line equations and solving for m and b respectively, we find that the value of b + m is -7.

To find the value of b + m when two lines intersect at the point (6, 10), we can substitute the coordinates of the intersection point into both line equations. Since the coordinates (6, 10) must satisfy both equations, we have:

For the first equation y = mx + 4:
10 = m*6 + 4,
which simplifies to:
m = 1.

For the second equation y = 3x + b:
10 = 3*6 + b,
which simplifies to:
b = -8.

Having both values, we can now calculate b + m:
b + m = (-8) + 1 = -7.

The value of b + m is -7, which represents the sum of the y-intercept of the second line and the slope of the first line.
