I need to find the x of the triangle.

Answer:

2.75x+122.5

Step-by-step explanation:

Horse=x

Stork=x+70

Whale=3/4(x+70) = 0.75(x+70) = 0.75x+52.5

x+x=70+0.75x+52.5

2.75x+122.5

Answer:

2.75h + 122.5, where h = lifespan of a horse

Step-by-step explanation:

The whale's lifespan is given in terms of the stork's.

The stork's lifespan is given in terms of the horse's.

Start by assuming a variable for the lifespan of a horse.

Let h = the lifespan of horse in years.

A horse lives h years.

A stork lives 70 years longer than a horse. A stork lives h + 70 years.

A whale lives 3/4 of the lifespan of a stork. A whale lives for (3/4)(h + 70) years.

Now that you have an expression for the lifespan of each animal, the total lifespan of the three animals is the sum of the three lifespans.

total lifespan = h + h + 70 + (3/4)(h + 70

Now we simplify the right side.

total lifespan = 2h + 70 + (3/4)h + (3/4)(70)

total lifespan = 2h + 70 + 0.75h + 52.5

total lifespan = 2.75h + 122.5

Answer: 2.75h + 122.5, where h = lifespan of a horse

Step-by-step explanation:

Total Number of pens = 5

Number of defective pens = 2

Number of non-defective pens = 3

A.) number of defective pens selected :

X : {0, 1, 2}

It is possible that no defective pen will be selected ; 1 defective will be chosen or both pens are defective.

2.)

Defective as Success (since selecting a defective pen is the point of interest.

3.)

Since selection is done without replacement

Probability of success per selection is different for each selection ;

Number of defective = 2

Number of observations = 5

P(success on first selection) = 2/5

P(success on second selection) = 1/4

Hence, X is not well approximated by a binomial random variable.

4.) if selection is done with replacement ; then then the probability of success per selection will be the Same for each selection made. Hence, X will be well approximated by a binomial Random variable.

5.) If sampling is done without replacement, then the the hypergeometric function will be a more effective approximation.

Answer:

  (a)  15

Step-by-step explanation:

Each of the marked angles is an exterior angle of the polygon. The sum of exterior angles is always 360°. We can use that fact to write the equation.

  4x° +77° +59° +6x° +74° = 360° . . . . . an equation to find x

  10x + 210 = 360 . . . . . . . . . . . . . . divide by °, collect terms

  x + 21 = 36 . . . . . . . . . . . . . . . divide by 10

  x = 15 .  . . . . . . . . . . . . . . subtract 21

_____

Comment on the sum of exterior angles

Imagine the figure shrunk smaller and smaller until all of the angle vertices are the same point. You can see that those angles will completely fill the angular space around that central point, so they must have a sum of 360°.

Answer:

0.57 inches of rainfall is equivalent to 6 inches of snow

Step-by-step explanation:

The given data are presented here as follows;

[tex]\begin{array}{cc}x&y\\16&1.5\\12&1.3\\18&1.8\\15&1.5\\20&2.1\\23&2.4\\\end{array}[/tex]

The data points are approximately linear

From the the trend line of the plotted points of the graph, created with Microsoft Excel, with Forecasting, when there is 6 inches of snow the rainfall is 0.575 inches

By linear regression, we have;

Y = a + b·X

Where;

[tex]b = \dfrac{n \cdot \sum XY - \left (\sum X \right ) \cdot \left (\sum Y \right )}{n \cdot \sum X^{2} - \left (\sum X \right )^{2}}[/tex]

[tex]a = \dfrac{\sum Y - b \cdot \sum X}{n}[/tex]

∑x = 104

∑y = 10.6

∑(x·y) = 191.7

(∑x)·(∑y) = 1102.4

(∑x)² = 10816

n = 6

SigX^2 = 1878

Plugging in the values, gives;

[tex]b = \dfrac{6 \times191.7 - 1102.4}{6 \times 1878 - 10816} \approx 0.10575[/tex]

[tex]a = \dfrac{10.6 - 0.10575 \times 104}{6} \approx -0.06637[/tex]

Therefore;

Y = 0.10575·x - 0.06637

When x = 6 inches, we have;

Y = 0.10575 × 6 - 0.06637 = 0.56813

Y = 0.56813 inches ≈ 0.57 inches of rainfall

Therefore;

0.57 inches of rainfall is equivalent to 6 inches of snow

Answer:

4x = 180

Step-by-step explanation:

angle x = angle y so we can say both angles are 'x + x' or '2x'

angle z = twice angle y (or twice angle x because they're equal) so we can say angle z = 2x

2x + 2x = 180

The next 3 terms from the geometric sequence below.

Step-by-step explanation:

The next 3 terms of the geometric sequence are [tex]\frac{1}{4} , -\frac{1}{8}, \frac{1}{16}[/tex].

'A geometric sequence is a special type of sequence where the ratio of every two successive terms is a constant. This ratio is known as a common ratio of the geometric sequence.'

According to the given problem,

The terms are, -2 , 1 , - [tex]\frac{1}{2}[/tex] ....

Now, geometric sequence means that there is a common ratio between the numbers in the sequence.

Common ratio can also be denoted as r.

so, from -2, the next term is -2 × r and the one after this is -2 × r × r and so on.

If we compare, -2 × - [tex]\frac{1}{2}[/tex] = 1

                           1 × -[tex]\frac{1}{2}[/tex] = -[tex]\frac{1}{2}[/tex]

                           -[tex]\frac{1}{2}[/tex] × -[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{4}[/tex]

                            [tex]\frac{1}{4}[/tex] × -[tex]\frac{1}{2}[/tex] = -[tex]\frac{1}{8}[/tex]

                           -[tex]\frac{1}{8}[/tex] × -[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{16}[/tex]

Hence, we can conclude that the next three terms are, [tex]\frac{1}{4}[/tex] , -[tex]\frac{1}{8}[/tex] ,  [tex]\frac{1}{16}[/tex].

Answer:

[tex]\displaystyle (fg)(-\frac{1}{5})=0[/tex]

Step-by-step explanation:

We are given the two functions:

[tex]f(x)=x^2-13\text{ and } g(x)=5x+1[/tex]

And we want to find:

[tex]\displaystyle (fg)(-\frac{1}{5})[/tex]

This is equivalent to:

[tex]\displaystyle =f(-\frac{1}{5})g(-\frac{1}{5})[/tex]

By substitution:

[tex]\displaystyle f(-\frac{1}{5})=(-\frac{1}{5})^2-13=\frac{1}{25}-13=-\frac{324}{25}[/tex]

And:

[tex]\displaystyle g(-\frac{1}{5})=5(-\frac{1}{5})+1=-1+1=0[/tex]

Hence:

[tex]\displaystyle =(-\frac{324}{25})(0)=0[/tex]

Our final answer is:

[tex]\displaystyle (fg)(-\frac{1}{5})=0[/tex]
