Answer:

$36

Step-by-step explanation:

What we know: The jacket is marked up by 80% of the jacket. The store is now selling the jacket for 180% of what they bought it for.

Set up problem:    x        180%

                            ___ = ____

                           $20     100%

What do the numbers mean when set up like this(referring to problem set up): We know that $20 is the original price of the jacket. So $20 is 100% of the jacket(if that makes sense). Markup is 80% because "sells it for 80% more" . So it goes on top.

Solving the Problem#1:  180 x 20 = 3600

Solving the Problem#2: 3600/1000= $36

Checking My Math: What is 80% of $20. Let's divide $20 into 4 parts.  

$4 + $4 + $4 + $4 + $4 =20

$4 is 20% of 20

$8 is 40% of 20

$12 is 60% of 20

$16 is 80% of 20

$20 is 100% of 20

Final Answer: $36 is the selling price of the jacket

Step-by-step explanation:

You have to multiply the total members by the percentage.

20X[tex]\frac{20}{100}[/tex] =4

Answer:

[tex]-8 \times \frac{-2}{3}\\\\= \frac{-8 \times -2}{3} \\\\= \frac{16}{3}[/tex]

Answer:

The standard form of the ellipse is [tex]\frac{x^{2}}{25} +\frac{y^{2}}{169} = 1[/tex]. Coordinates of the foci are [tex]F_{1} (x,y) = (0,-c)[/tex] and [tex]F_{2}(x,y) = (0,c)[/tex], respectively.

Step-by-step explanation:

The equation of a ellipse centered in the origin in standard form is defined by following formula:

[tex]\frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}} = 1[/tex] (1)

Where [tex]a, b[/tex] are the coefficients of the ellipse.

Now we proceed to transform the equation of the ellipse in general form into standard form by algebraic means:

[tex]169\cdot x^{2}+25\cdot y^{2}-4225 = 0[/tex]

[tex]169\cdot x^{2}+25\cdot y^{2} = 4225[/tex]

[tex]\frac{x^{2}}{25} +\frac{y^{2}}{169} = 1[/tex]

Since [tex]b > a[/tex], then major axis of the ellipse is located in y-axis. The distance between center and focus ([tex]c[/tex]) is calculated by following Pythagorean identity:

[tex]c =\sqrt{b^{2}-a^{2}}[/tex] (2)

[tex]c = 12[/tex]

The location of the foci are represented by [tex]F_{1} (x,y) = (0,-c)[/tex] and [tex]F_{2}(x,y) = (0,c)[/tex]. If we know that [tex]c = 12[/tex], then the location of the foci are, respectively:

[tex]F_{1}(x,y) = (0,-12)[/tex], [tex]F_{2}(x,y) = (0,12)[/tex]

Answer:

What is acceleration?

Imagine you are playing golf, and you’ve just set up the golf ball on the tee. You test your grip, take a few practice swings, and peer into the distance at the flag pole marking the first hole for the course. Your wise golf ball guru (who happens to also teach physics) tells you to “Be the ball, young grasshopper.” So you close your eyes and picture the distance the ball must travel. “Yes, young earthworm”, your sensei says, “that distance you see is the displacement you must achieve, displacement is the change in position from one place to another.”

Answer:

Infinite solutions

Step-by-step explanation:

Suppose there are finite solutions to x > 12

Then there exists a largest solution, which we call X

But X + 1 > X, and X > 12, so by transitivity X + 1 > 12 and thus is an even larger solution

this means X is not the largest solution

Therefore, by contradiction, the assumption that there are only finite solutions is false

Answer:

$707.9941 rounded is $707.99

Step-by-step explanation:

41%=0.41

1199.99*0.41=491.9959

$1199.99-$491.9959=$707.9941

$707.9941 rounded is $707.99

the four doesn't round up so it would just be $707.99.

Hope this helped!

Answer:

Step-by-step explanation:

x2 - 2x - 35

First we have to find the factors of 35 that by subtracting equal to 2 so

x2 - 7x + 5x - 35

Taking common

x(x - 7) + 5(x - 7)

(x - 7) and (x + 5) are the factors

9 of the 20 drawn were red

9/20* 100 = 45

Answer:

A. 10

Step-by-step explanation:

Formula for the Pythagorean Theorem: a^2+b^2=c^2

Substitute: 6^2+8^2=c^2

6*6+8*8=c^2

36+64=c^2

100=c^2

Then, find we to the square root in order to isolate c^2.

10=c.

Final answer, A. 10.

Answer:

H0; u = 50 average revenue equals 50

H1: u not equal to 50, average revenue not equal to 50

This is 2 tailed

Alpha = 0.05

Z critical = 1.6449

We find the test statistics

Mean = 54.7

Sd = 11

n = 32

barX - u/sd/√n

= 54.70-50/11/√32

= 4.70/1.9435

= 2.418

Decision rule: reject H0 if test statistic > critical value. Accept if otherwise

2.418>1.6449

We reject H0

We conclude that average revenue is not equal to zero

C. P(z>=2.418) = 0.9922

1 - 0.9922

= 0.0078 (I used Ms excel here)

0.0078 < 0.05

So we Reject h0

Answer:

8/15 +5/15 = 12/15 = 4/5

Step-by-step explanation:

Answer:

$12

$8

Step-by-step explanation:

Amount Jatin received = (ratio of Jatin's share / sum of ratios) x amount shared

sum of ratios = 3 + 2 = 5

(3/5) x 20 = $12

Amount Arnav received = (ratio of Arnav's share / sum of ratios) x amount shared

(2/5) x 20 = $8

or

$20 - $12 = $8

Answer:

X

Step-by-step explanation:

The X-axis is the one on the bottom if you are in the first quadrant. The y-axis is on the left or up and down. If you are writing location(I can't remember the name but it looks like this (2,3)) you would write the X-axis down first. Hope this helped!  

Answer:

0.0049 = 0.49% probability that she actually has breast cancer

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Positive test result

Event B: Breast cancer

Probability of a positive test result:

4% of (1 - 0.0002)

98% of 0.0002

So

[tex]P(A) = 0.04*(1 - 0.0002) + 0.98*0.0002 = 0.040188[/tex]

Having breast cancer and testing positive.

98% of 0.0002

So

[tex]P(A \cap B) = 0.98*0.0002 = 0.000196[/tex]

What is the probability that she actually has breast cancer?

[tex]P(B|A) = \frac{0.000196}{0.040188} = 0.0049[/tex]

0.0049 = 0.49% probability that she actually has breast cancer

Answer:

C.

Step-by-step explanation:

The bottom-right most cell tells us that the total number of students that responded to the survey is 310 students.

To find the answer, we can go through each choice.

A. Females taking Geometry

Row 1 Column 2 tells us that 53 females are taking geometry. 53/310 is about 17%.

B. Females taking Algebra II.

Row 1 Colume 3 tells us that 62 females are taking Algebra II. 62/310 is 20%.

C. Males taking Geometry.

Row 2 Colume 2 tells us that 59 males are taking Geometry. 59/310 is about 19%. Choice C is correct.

D. Males taking Algebra I.

44 out of the total 310 respondents are male and is taking Algebra I. 44/310 is about 14%.

Answer:

C

Step-by-step explanation:

59/310 *100 = 19.03%

so 19%
