Answer:

X=25

Step-by-step explanation:

This is because X has to be greater than 23. Because you are taking away 35 and the answer is 2, you have to add 23 and 2, and that gives you 25!

an = 3/2 a_n-1

Let's try it out.

take 3/2 of 6.75       Multiply by 3 first

(3 * 6.75 ) / 2

20.25 / 2

10.125 which is what happens.

Answer:

THis is a function.

Step-by-step explanation:

If you draw a straight line vertically, it won't intersect more than one point of the line. This is called the vertical line test, and if the line you drew passes the line on the graph more than once, its not a function.

Answer:

There are few kind of statistics: first of all - Mathematiсal statistics. This is quite a mathematical science.

Its applications widely used in many branches of science. First of all (for me) in measurement theory. When used correctly, there is no objection to this science and its methods.

The use in the so-called "social sciences", primarily in sociology, raises many questions: first and foremost - how representative is the "sample"? To what extent does the question asked by the respondent dictate the “correct” (expected) answer? And so on. Of course, this is not a statistic, but mostly a science-like hype, covering up the absence of objective methods.

First, reflection over the x- axis, then a horizontal translation 3 units to the right and 3 units up.

Step-by-step explanation:

Order does not matter. The - before the (x-3) makes a reflection over the x-axis. Then, the -3 in the (x-3) makes the graph translate 3 units to the right, and the +3 is 3 units up.

Answer: [tex]y = 5^x+2[/tex]

The 2 is not in the exponent.

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

Explanation:

As x gets smaller and smaller, going off into the negative direction forever, the expression [tex]5^x[/tex] will approach 0. This is because we're computing stuff like 5^(-1) = 1/5 = 0.2 and 5^(-2) = 1/25 = 0.04 and so on. The decimal values are approaching 0 but never actually arrive there. The range of [tex]y = 5^x[/tex] is [tex](0,\infty)[/tex]

Adding on the 2 at the end will shift everything up so that the range is now [tex](2,\infty)[/tex]. Refer to the graph below.

The parenthesis in interval notation mean we do not include that endpoint as part of the set. Saying something like [tex](2,\infty)[/tex] is the same as saying [tex]2 < y <\infty[/tex] when talking about the range.

Answer:

C.

Step-by-step explanation:

Scatterplots with weak correlation coefficients are values near zero

The false statement about the correlation coefficient is r = 0 shows that two variables are strongly correlated.

A statistical metric known as correlation illustrates how closely two variables are connected and how they tend to move in tandem. When two variables are positively correlated, they move in the same direction, and when they are negatively correlated, they move in the opposite way. To determine the degree and direction of the association between two variables, a correlation coefficient is utilized.

A correlation coefficient of -1 indicates a perfect negative correlation, a correlation coefficient of 1 indicates a perfect positive correlation, and a correlation coefficient of 0 indicates no correlation between the two variables.

Given data ,

The FALSE statement is:

c. The correlation coefficient r = 0 shows that two variables are strongly correlated.

A correlation coefficient of 0 means that there is no linear relationship between the two variables. It does not indicate the strength of the relationship.

A value of r = 0 indicates that there is no association between the two variables, whereas a value of r = 1 or r = -1 indicates a perfect positive or negative association, respectively.

Answer:

Step-by-step explanation:

w = w

L = 9*w - 29

Area = L*w

area = 9418

w * (9w - 29) = 9418

9w^2 - 29w - 9418 = 0   This monster factors, believe it or not

(9w + 277)(w - 34) = 0

9w + 277 =0

9w = - 277

w = -30.777778

w - 34 = 0

w = 34

The length = 9w - 29

L = 9*34 - 29

L = 306 - 29

L = 277

Check

Area = L * w

Area = 277 * 34

Area = 9418 just as it should.

Answer:

$31.96

Step-by-step explanation:

To find how many gallons you need, divide 320 by 34.

[tex]\frac{320}{34} =9.4 (rounded-to-the-nearest-cent)[/tex]

So now that we know we need 9.4 gallons, we multiply 9.4 times the price per gallon ($3.40)

9.4 x $3.40 = $31.96

Answer:

$30

Step-by-step explanation:

d + s= 86.50----------1

d - 25.50 = s

d - s=25.50------------2

1 - 2

(d-d) +(s-(-s))=86.50-25.50

2s=60

s=60/2=$30

The cost of a stool is $30.5 if the total cost of a desk and a stool is $86.50 and the stool costs $25.50 less than the desk.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The total cost of a desk and a stool is $86.50.

The stool costs $25.50 less than the desk.

Let the cost of the desk is $d

Let the cost of the stool is $s

d + s = 86.50
s = d - 25.50

The above two equations represent two linear equations in two variables.

By solving by substitution method:

Plug s = d - 25.50 in the first equation

d + d - 25.50 = 86.50

2d = 86.50 + 25.50

2d = 112

d = 112/2

d = $56

s = 86.50 - 56

s = $30.5

Thus, the cost of a stool is $30.5 if the total cost of a desk and a stool is $86.50 and the stool costs $25.50 less than the desk.

Step-by-step explanation:

Before we answer, the area of a Circle given it radius is

[tex]a = \pi r {}^{2} [/tex]

The area of a circle given it diameter is

[tex]a = \pi( \frac{d}{2} ) {}^{2} [/tex]

So let answers question 1-4.

1. The area is

[tex]1024\pi[/tex]

2. The area is

[tex]576\pi[/tex]

3.

[tex]1.225\pi[/tex]

4.

[tex]309.76\pi[/tex]

For the 5th problem, circumference is

[tex]\pi \times d[/tex]

where d is the diameter and

[tex]2\pi r[/tex]

where r is the radius.

A circumference of 100 m means the radius is 50 because

[tex]2\pi \times r = 100\pi[/tex]

[tex]r = 50[/tex]

So this means the area is

Answer:

h = 3 sqrt(21)

or

h = 13.75

Step-by-step explanation:

The perimeter of the rhombus is 60 feet. Like a square, all the sides of a rhombus are equal. Therefore your first step is to find FK which is a side.

FK = 60/4 = 15 feet.

Now you can use the Pythagorean Theorem.

a^2 + b^2 = c^2

a = 6

b = height or = h

c = 15

6^2 + b^2 = 15^2

36 + b^2 = 225

b^2 = 225 - 36

b^2 = 189

sqrt(b^2)= sqrt(189)

b = sqrt(3 * 3 * 3 * 7)  You can take out the square of 3 * 3 and make it 3.

b = 3 * sqrt(3*7)

b = 3 * sqrt(21)
