Answer:

x = -6

Step-by-step explanation:

3x + 17 = -2x - 13

==> add 2x to both sides

5x + 17 = - 13

==> subtract 17 from both sides

5x = -30

==> divide both sides by 5

x = -6

He may or not be correct. It depends on the profit you make on each sundae cup compared with the profit on the other treat.  The other treat  might give a higher profit.

Omar is correct since if 50% of the

Profit is defined as the amount gained by a person or business.

Profit = Total Revenues - Total cost

Given that,

you and Omar are talking about which two frozen treats would be best to sell.

Omar claims that because 50% of the frozen treats sold in Week 1 were sundae cups, the sundae cups accounted for 50 % of the profit.

Total number of the frozen treats = 100%

If 50% of the frozen treats sold in Week 1 were sundae cups, then the profit of the frozen treats will be 50% of the total which came from sundae cups.

Hence Omar is correct.

The surface area of the covering of the cone to the nearest square inches is 788 inches²

surface area of a cone = πr(r + l)

where

Therefore,

diameter = 2(radius)

14 = 2r

r = 14 / 2

r = 7 inches

l² = 7² + 28²

l = √49 + 784

l = √833

l = 28.8617393793

l = 28.86 inches

Therefore,

surface area = 3.14 × 7 (7 + 28.86)

surface area = 21.98 × 35.86

surface area = 788.2028

surface area = 788 inches²

The y-intercept is the b term in slope intercept form (y = mx + b) or in the form of a point (0, y).

Function 1 is in slope-intercept form, and the b term is 5.

Function 2 is given in a table, but it is easy to find the point (0, y) and y is 5.25.

5.25 > 5

Function 2 has the greater y-intercept.

1) The mean of set A is larger than the mean of set B.

2)The median of set A is larger than the median of set B.

A = {10, 12, 12, 6, 8, 5, 4, 10, 8, 10, 12, 12, 6}

B = {8, 8, 8, 7, 9, 7, 9, 10, 6, 8}

Mean is the ratio of the sum to the total number of observations.

Mean of set A = 115/13

Mean of set B =80/10 =8

So, the mean of set A is larger than the mean of set B.

Arranging both the sets in ascending order

A = {4, 5, 6, 6, 8, 8, 10, 10, 10 12, 12, 12, 12 }

Median of set A = middle term = 7th term = 10

Similarly, the median of set B =8

So, the median of set A is larger than the median of set B.

Thus, 1) The mean of set A is larger than the mean of set B.

2)The median of set A is larger than the median of set B.

Step-by-step explanation:

I took the assignment and these are right. :)

The expected value is 50 then Carmen’s prediction is low because 200 times one-fourth is 50. Then the correct option is B.

Expectation can be taken as a weighted mean, weights being the probability of occurrence of that specific observation.

Thus, if the random variable is X, and its probability mass function is given as

[tex]E(X) = \sum_{i=1}^n( f(x_i) \times x_i)[/tex]

(n is the number of values X takes)

Carmen is going to roll an 8-sided die 200 times.

She predicts that she will roll a multiple of 4 twenty-five times.

The sample will be

Total event = 8 {1, 2, 3, 4, 5, 6, 7, 8}

Then the favorable event will be to roll an 8-sided die and get a multiple of 4. Then we have

Favorable event = 2 {4, 8}

Then the probability will be

[tex]\rm P = \dfrac{2}{8} = \dfrac{1}{4}[/tex]

A dice is rolled 200 times, then by the binomial theorem we have the expected value will be

[tex]E(x) = nP = 200 \times \dfrac{1}{4} = 50[/tex]

Answer:

18cm

if it takes 12cm to wrap 6 presents, it means it takes 2cm to wrap one present.

9 individual presents will take 2 wraps, so Dwayne needs 18cm of wrapping paper.

Sum of the interior angles of any n-side shape must equals to :

Thus ;

[tex](5 - 2) \times 180 = [/tex]

Answer:

x = 16/3, y = -1/9

Step-by-step explanation:

4x + 1 = 5(x-3y) - 6

3(x+6y) + 4 = 9y + 19

Simplify both equations

4x + 1 = 5x-15y - 6

-x + 15y = -7

3x + 18y + 4 = 9y + 19

3x + 9y = 15

Now multiply 3 on both sides for the first equation.

(easier for adding both equations)

-3x + 45y = -21

3x + 9y = 15

Add both equations

x cancels out

54 y = -6

y = -1/9

plug in to other equation

3x + 9y = 15

3x - 1 = 15

3x = 16

x = 16/3

Answer:

y = -1x + 3 or y = -x + 3 (**That is the last option which is D**)

Step-by-step explanation:

You need to do slope-intercept formula and the slope formula.

The Slope-Intercept Formula: y=mx+b

The Slope Formula: y2 - y1 / x2-x1

Your coordinates:

(-1,4) and (1,2)

2 - 4/1- (-1)

-2/2

Simplified is -1

Your "m" in the slope-intercept formula is -1

Formula: y=-1x + b

Now, you need to find the Y-Intercept which is the "b"

Using our slope-intercept formula, you need to plug in "x1" and "y1"

4 = -1(-1) + b

4 = 1 +b

4-1 = b

3 = b

So your equation is:

y = -1x + 3 or y = -x + 3
