A stem-and-leaf plot shows the data shape and the densities of the different classes in a graphical form such that the information in the data such as the data characteristics are self displayed by the data numbers arranged in the stem-and-leaf plot. The stem-and-leaf plot keeps the raw numerical data, in the form they were obtained and by their arrangement, outliers are easily spotted.

Hope this helped! Let me know if you have further questions! :)

The factors of 27 are 1,3,9,27.

When figures are translated, rotated or reflected, the resulting figures are congruent to the original figure because the transformations are rigid. However, when a figure is dilated, the resulting figure is not congruent to the original figure.

ABCD and A'B'C'D are congruent because A'B'C'D is the result of rotating ABCD 180 degrees about the origin.

I've included the missing graph as an attachment.

Using points A and A' as our references.

We have:

[tex]A = (-1,1)[/tex]

[tex]A' = (1,-1)[/tex]

The rule of rotation 180 degrees about the origin is:

[tex](x,y) \to (-x,-y)[/tex]

So, we have:

[tex](-1,1) \to (-(-1),-1)[/tex]

[tex](-1,1) \to (1,-1)[/tex]

The above rule is applicable to other points in ABCD and A'B'C'D'

Since the rule of transformation is rotation (a rigid transformation), then ABCD and A'B'C'D are congruent.

Based on the relationship between Mary's age and that of John, the representation of Mary's age is (X + 5).

Your question seems incomplete or not worded well so I'll give a more general response.

Mary is said to be older than John by 5 years. This means that however old John gets, Mary will always be older by 5 years.

If John is X years therefore, Mary's age will simply be:

= John's age + Age difference

= X + 5

For instance, if John is 20 years then Mary would be:

= 20 + 5

= 25 years

Answer: The photo will be 36 inches tall.

Given:

Original width or breadth (L1) of the rectangular photo = 6 inches

Original height or length (L1) of the rectangular photo = 12 inches

Original area (A1) = B1 x L1

= 6 x 12 = 72 square inches

New width (B2) = 2 inches

According to the question, original area (A1) should be equal to new area (A2).

Therefore, let us formulate:

A1 = A2

B1 x L1 = B2 x L2

The value of L2 is unknown.

So, 72 = 2 x L2

By the method of transposition,

L2 = 72 ÷ 2 = 36 inches

Step-by-step explanation:

From both the cases we can say that √n is either a natural number or an irrational number. Hence the correct option is (d)Either a natural number or an irrational number.

Step-by-step explanation:

Remark

I have to assume that you know calculus. It is the only way the problem can be done that I know of. If you don't, I'm not sure how you will do this.

The curve is of y  = e^(-2x) + x^2 - 3

The curve crosses the y axis when x = 0. The y value is

y = e^0 + x^2 - 3

yint = 1 + 0 - 3

yint = -2

The slope at point (0,-2) is

y' = -2e^(-2x) +2x

y' = -2 at point A

Therefore the normal will have a slope

m1 * m2 = - 1

The slope of the curve C  at A = -2

The equation of the tangent line at A = -2x - 2

Call this m1

m2 = slope of the normal

-2 * m2 = -1

m2 = 1/2

Equation of the line (l) =

y = 1/2 x  - 2

Answer:

C. 98

Step-by-step explanation:

If you add all of his previous test scores and go through the list of numbers you get C.98 as the answer. I added all of his test scores plus 98 which equals 630 divided by 7 (because if he got a 98 there would be 7 test scores) you would get 90 or an A average.

=============================================================

Explanation:

Let x be the next test grade. It ranges from 0 to 100, inclusive of both endpoints.

The original set {87,92,90,84,88,91} becomes {87,92,90,84,88,91,x} after adding on that score.

We have 7 scores now. We find the average by adding up those seven scores and dividing by 7.

average = (sum of the scores)/(number of scores)

average = (87+92+90+84+88+91+x)/7

average = (532+x)/7

We want the average to be 90 or higher, so we would then have these steps

[tex]\text{average} \ge 90\\\\\frac{532+x}{7} \ge 90\\\\532+x \ge 90*7\\\\532+x \ge 630\\\\x \ge 630-532\\\\x \ge 98\\\\[/tex]

This means Edgar must score a 98 or higher on the seventh test in order for his overall average to be 90 or higher.

In other words, the lowest test score he can get is a 98.

------------------

Extra info (optional section):

Let's say Edgar gets the highest score possible.

So he gets x = 100

This would mean

average = (87+92+90+84+88+91+x)/7

average = (532+x)/7

average = (532+100)/7

average = 632/7

average = 90.2857 which is approximate

We can see that his overall average would stick to 90 if the teacher is rounding to the nearest whole number.

Answer:

s = 5

Step-by-step explanation:

9* number of scarves in each box after removing 1 scarf = 36

9 *(s -1) = 36

9s - 9 =  36   {Distributive property}

9s = 36+ 9     {add 9 to both sides}

9s = 45

s= 45/9  {Divide both sides by 9}

s = 5

The sum of a number is the answer to addition. So that means an unknown number and 6 are being added together. Lets make this unknown number x.

The net cost after discounts will be $ 2,450.

Given that Economy Hardware Store ordered items retailing for $ 2,500, and they received a chain discount of 5/20/2, the following calculation must be performed to find the net cost, knowing that the net cost is equal to the initial cost minus the discounts made about it:

First, the discount percentage must be calculated.

5/20/2 = X

4/2 = X

2 = X

Then, this percentage must be subtracted from the initial value.

2500 x (1-0.02) = X

2500 x 0.98 = X

2450 = X

Therefore, the net cost after discounts will be $ 2,450.
