The length of the longest slide is 5 inches. he other two sides will be 4  inches in length.

Isosceles triangle

Given:

Total length=13 inches

Hence:

AC=BC<AB

Let AC=BC=x-1 inches

AB=x inches

Thus:

x-1+(x-1)+x=13

3x-2=13

3x=13+2

3x=15

divide both side by 3x

x=15/3

x=5 inches

Hence:

Other two side

x-1=5-1=4 inches

Therefore the length of the longest slide is 5 inches. he other two sides will be 4  inches in length.

Answer:

19.5625

Step-by-step explanation:

To find the mean, you add all of your values together and divide by the number of values you have.

Here are the values in the dot plot listed:

12, 12, 15, 15, 15, 15, 16, 18, 20, 20, 22, 25, 25, 25, 29, 29

To find the mean:

(12 + 12 + 15 + 15 + 15 + 15 + 16 + 18 + 20 + 20 + 22 + 25 + 25 + 25 + 29 + 29)/16 = 19.5625

Answer:

x = 81

Steps:

It says that y ~ √x

We have points (9, 18) as a guide.

We can write y = f(x) = a√x +b

Use points (9, 18) as a guide

18 = a√9 +b

18 = 3a + b

One solution might be a = 6, which means f(x) = 6√x

Thus when y = 54,

54 = 6√x

9 = √x

81 = x

The amount of co2 that Harry's vehicle would release to the atmosphere in a year is 12,000 pounds.

The first step is to determine the gallons of gasoline that the car would need in a year: 15,000 / 25 = 600 gallons

The second step is to determine the total emissions when the car uses 600 gallons: 600 x 20 = 12,000 pounds

Answer:

x < - 3

Step-by-step explanation:

4x + 2 > 6x + 8

=> 4x - 6x > 8 - 2

=> -2x > 6

Divide by -2 (Since dividing by -ve, operator sign changes)

=> x < - 3

Answer: x >-3

Step-by-step explanation: 4x + 2 > 6x + 8

4x - 6x = -2x

6x - 6x = 0

-2x + 2 >8

8 -2 = 6

2-2 = 0

-2x > 6

-2x/-2x = 0

6/-2x = -3

therefore x >-3

The linear regression equation that represents this data set is equal to y = 120.8x + 2,114.

First of all, we would determine the slope of the given data set by using this formula:

[tex]Slope = \frac{\sum (x-\bar x)(y-\bar y)}{\sum (x-\bar x)^2}[/tex]

For the sample mean (years), we have:

[tex]\bar x = \frac{0\;+\;1+\;2\;+\;3\;+4}{5} \\\\\bar x =\frac{15}{4} \\\\\bar x =3.75[/tex]

For the sample mean (cases), we have:

[tex]\bar y = \frac{904\;+\;900+\;833\;+\;837\;+754}{5} \\\\\bar y =\frac{4,228}{4} \\\\\bar y =1057[/tex]

The sums are given by:

∑(x - |x|) = (0 - 3.75) + (1 - 3.75) + (2 - 3.75) + (3 - 3.75) + (4 - 3.75)

∑(x - |x|) = - 3.75 - 2.75 - 1.75 - 0.75) + 0.25

∑(x - |x|) = -8.75.

∑(x - |x|)² = (-8.75)² = 76.5625.

∑(y - |y|) = (904 - 1057) + (900 - 1057) + (833 - 1057) + (837 - 1057) + (754 - 1057)

∑(y - |y|) = -153 - 157 - 224 - 220 - 303

∑(y - |y|) = -1,057‬.

∑(x - |x|)(y - |y|) = -8.75 × -1057

∑(x - |x|)(y - |y|) = 9,248.75.

Now, we can determine the slope:

Slope = 9,248.75/76.5625

Slope = 120.8‬.

Therefore, the equation is given by:

y = 120.8x + a

Next, we would find the value of a:

1057 = 120.8(-8.75) + a

a = 1057 + 1,057

a = 2,114.

Hence, the linear regression model is given by:

y = 120.8x + 2,114.

Since the new cases would reach 579, the calendar year would be calculated as follows:

579 = 120.8x + 2,114

120.8x = 579 - 2,114

120.8x = -1,535

x = -1,535/120.8

x = -12.71.

Year = 2014 + 12.71

Year = 2026.71 ≈ 2027.

Answer:

missing side is 5x - 4

Step-by-step explanation:

x - 1 + ( 3x + 6 ) + third side = 9x + 1

x - 1 + 3x + 6 + third side = 9x + 1

4x + 5 + third side = 9x + 1

third side = 9x + 1 - ( 4x + 5 )

third side = 9x + 1 - 4x - 5

third side = 5x - 4

Step-by-step explanation:

Answer:  Choice B.  3√2

This is the same as writing 3sqrt(2) or [tex]3\sqrt{2}[/tex]

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

Reason:

For any complex number of the form [tex]z = a+bi[/tex], the absolute value or magnitude of it is [tex]|z| = \sqrt{a^2+b^2}[/tex]

In this case, we have [tex]a = -4 \text{ and } b = -\sqrt{2}[/tex]

So,

[tex]|z| = \sqrt{a^2+b^2}\\\\|z| = \sqrt{(-4)^2+(-\sqrt{2})^2}\\\\|z| = \sqrt{16+2}\\\\|z| = \sqrt{18}\\\\|z| = \sqrt{9*2}\\\\|z| = \sqrt{9}*\sqrt{2}\\\\|z| = 3\sqrt{2}\\\\[/tex]

If we formed a segment with the endpoints [tex](0,0) \text{ and } (-4, -\sqrt{2} )[/tex], then that segment will have length of the value mentioned above.

The tree diagram that represents the events is an illustration of probability and combination

To draw the tree diagram, we make use of the following representations:

See attachment for the tree diagram.

From the tree diagram, the sample space is as follows:

S = {HR, HY, HB, TR, TY, TB}

This is represented as: TY

From the sample space above, we have:

TY = 1

Hence, the number of outcomes that represents "Toss a tail, spin yellow" is 1

We have:

TY = 1

Sample size = 6

Hence, the  of tossing tails and spinning yellow is 1/6

The five number summary is

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

Further Explanation:

The original data set is {24, 32, 25, 27, 37, 29, 30, 30, 28, 31, 27, 23}

It sorts to {23, 24, 25, 27, 27, 28, 29, 30, 30, 31, 32, 37} when going from smallest to largest.

There are n = 12 items in this set. The median is found between slots 6 and 7 because n/2 = 12/2 = 6

Circle the items in slot 6 and slot 7 to highlight 28 and 29 in that order. The midpoint is (28+29)/2 = 57/2 = 28.5 which is the median.

Median = 28.5

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

Now break the set up into two pieces

L = {23, 24, 25, 27, 27, 28}

U = {29, 30, 30, 31, 32, 37}

L is the lower set below the median, U is the upper set above the median

The midpoint of L is (25+27)/2 = 26 and the midpoint of set U is (30+31)/2 = 30.5

This gives us Q1 = 26 and Q3 = 30.5 respectively

Q1 = first quartile

Q3 = third quartile

The min and max are simply the smallest and largest items of the set

min = 23

max = 37

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

We have this five number summary:

These five items directly determine the positioning of the box and whiskers. No extra info is needed.

The min and max handle the tips of the left and right whiskers if we don't have any outliers. In this case, we don't have outliers so we can ignore this aspect.

The Q1 and Q3 handle the left and right edges of the box

The median (aka Q2) is the vertical line inside the box. It doesn't have to be at the center of the box. It's simply anywhere inside.

With all this in mind, the best match is choice D

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

In other words, we can eliminate the following

Since A, B, and C are eliminated, the only thing left is choice D which matches all aspects of the five number summary above.
