Answer:

6 and -3

Step-by-step explanation:

6 times -3 equals -18 because a positive times a negative equals a negative. 6 plus -3 equals 3, remember that a positive plus a negative can be rewritten as subtraction. So 6+(-3)=6-3, which equals 3.

Answer:

1.6627 (money wise, $1.66)

Step-by-step explanation:

Since its 130%, you know there was already a whole increase. So first you would do 1.279 + 1.279, which would give you 2.558. Then you need to calculate 30% of 1.279 for the rest of the increase. That gives you 0.3837 Add 2.558 and 0.3837 together, which would give you 2.9417. To get the INCREASE, you would have to subtract the new total from the original price, so 2.9417 - 1.279. This would give you 1.6627.

Answer:

8/9 + 1/6 = 1 1/18

Step-by-step explanation:

1. Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

8/9*2/2 + 1/6*3/3 = ?

2. Complete the multiplication and the equation becomes 16/18 + 3/18.

3. 16/18+3/18 = 19/18 = 1 1/18

The approximate solution to the trigonometric inequality will be 0<=x<0.7896. Option A is correct.

Inequality is a sort of equation in which the equal sign is missing. As we will see, inequality is defined as a statement regarding the relative magnitude of two claims.

Given inequality;

tan(x/4)<1/5

x/4 = tan⁻¹(1/5)

0<=x<0.7896

The approximate solution to the trigonometric inequality will be 0<=x<0.7896.

Hence option A is correct.

Answer:

Approximately 262%

Step-by-step explanation:

To find the percentage increase divide the new amount of offenses by the old amount of offenses:

2448/935 = 2.618

2.618 rounds to 2.62. Convert 2.62 into a percentage: 262%

The percentage increase between the amount of offenses in 2000 and the amount of offenses in 2019 is approximately 262%.

Answer:

the mean is 7.2 and the median is 8

Step-by-step explanation:

when you add up all the data you will get 36 which you divide by 5 since there are 5 different values.This will result to 7.2 as your final answer .Whereas for the median out of the 5 numbers the median would be the 3rd number which when you order them from smallest to largest it would be 8.

Answer:

60

Step-by-step explanation:

if we simplify 96/72 we get 4/3

now we can use it for n and 80 we know that 80 is the longer one so 4 is 80 in this case, now 80/4 equals 20, 3 x 20 = 60

Answer:

The first and third quartile of the wingspans are 116.9 cm and 133.1 cm respectively.

Step-by-step explanation:

The first and third quartile of a normal distribution are:

[tex]Q_{1}=\mu-0.675\sigma\\\\Q_{3}=\mu+0.675\sigma[/tex]

The information provided is as follows:

[tex]\mu=125\\\sigma=12[/tex]

Compute the first and third quartile of the wingspans as follows:

[tex]Q_{1}=\mu-0.675\sigma=125-(0.675\times 12)=116.9\\\\Q_{3}=\mu+0.675\sigma=125+(0.675\times 12)=133.1[/tex]

Thus, the first and third quartile of the wingspans are 116.9 cm and 133.1 cm respectively.

Assume the year that it would take to these trees have the same height is : x (years)

After x years, type A tree has heigth: 36 +23x (inches)

After x years, type B tree has heigth: 96 +17x (inches)

We have  36+23x = 96+17x

Solve the equation, we have x=10

Conclusion: It will take 10 years to these trees have the same height.

Answer:

2x + 5y = -4

Step-by-step explanation:

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

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

Explanation:

Let's use point slope form to get

y - y1 = m(x - x1)

y - y1 = -4(x - x1) .... plug in the given slope m = -4

y - 5 = -4(x - 2) .... plug in the given point (x1,y1) = (2,5)

Now we isolate y

y - 5 = -4(x - 2)

y - 5 = -4x + 8

y = -4x + 8 + 5

y = -4x + 13

This equation is in slope intercept form y = mx+b

m = -4 is the slope

b = 13 is the y intercept

To get this into standard form, we add 4x to both sides so that the x and y terms are on the left side

y = -4x+13

y+4x = 13

4x + y = 13 is the final answer

This is in standard form Ax+By = C where

A = 4

B = 1

C = 13

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

Let's check the answer. Plug in (x,y) = (2,5) to find that...

4x+y = 13

4*2 + 5 = 13

8 + 5 = 13

13 = 13

We get the same thing on both sides, so the last equation is true. This means the first equation is true when (x,y) = (2,5). This confirms the point (2,5) is on the line and helps confirm the answer.

Answer:

GO SEARCH MATH_WAY its a math calculator gives you  

Step-by-step explanation:

Part (A)

The input variable is the shoe size because it is along the horizontal axis, or x axis. It's not clear what the units for the shoe size are, but it's possible the units are in inches.

The output variable is the y value, which in this case is the height. The units for the height is in inches.

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

Part (B)

We have a positive trend. We determine this visually by noting the regression line, or trend line, is going upward as we move from left to right.

Algebraically, the equation for the trend line has a positive slope, which leads to a positive trend.

A positive trend is where x and y increase together. As shoe size goes up, height goes up as well.

While not all the points are on the line, there is a tendency for the points to go uphill as we move from left to right.

As for the strength of the correlation, that part is subjective. If we knew the correlation coefficient r, then we could be more certain; however, we don't know this value. So instead we have to eyeball the given graph and give an estimate. Based on the graph, I'd say there's a moderate positive correlation going on. It's somewhere in the middle of weak and strong positive correlation because the data points are somewhat scattered randomly, but they trend upward nonetheless.

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

Part (C)

The rate of change is the slope. The slope is the coefficient of the independent variable x. In this problem, the slope is 1.728

So the rate of change is 1.728 inches per shoe size.

In other words, as the shoe size increases by 1 unit (1 inch perhaps?), the height will increase by roughly 1.728 inches.

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

Extra info:

The equation

Height = 51.46 + 1.728(Shoe Size)

is the same as

y = 51.46 + 1.728x

where x is the shoe size and y is the height

We can rearrange that into

y = 1.728x + 51.46

So that it matches with the familiar y = mx+b slope intercept form. This is optional.

Answer:

The equation of the line (in slope-intercept form) is y=4x-9

Sam's swimming pool cleaning has 73 customers.

The correct option is d.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Sam's Swimming Pool Cleaning has an annual net income of $46,900.

Sam charges $25 per week for each of his customers for 52 weeks.

His annual operating expenses, including labor and supplies, are $48,000.

His total income,

= 46900 + 48000

= 94900.

The number of customers = 94900/(25 x 52) = 73.

Therefore, the number of customers is 73.
