Answer: For meters it is 3,000

Step-by-step explanation: Do 120 x 25= 3,000

Step-by-step explanation:

120 x 25 = 3000

270 ➗ 25 = 10.8

120 ➗ 4 = 30

3000 ➗ 25 = 120

270 ➗ 10.8 = 25

Answer:

  volume goes to 2.0 L

Step-by-step explanation:

At constant temperature, volume and pressure are inversely related. Increasing the pressure by a factor of 125/50 = 2.5 will cause the volume to be reduced by that factor.

  volume = 5.0L / 2.5

  volume = 2.0 L

Answer:

y = 3/4x - 2

Step-by-step explanation:

slope intercept form: y = mx + b

y-intercept(when x= 0) is given by b

slope is given by m

lets find the slope using the two given points, (4,1) and (8,4)

m = y2-y1 / x2-x1

m = 4 - 1 / 8 - 4

m = 3/4

Now use any of the given points to begin writing your equation, which will help you find the y intercept - ill use (4,1).

1 = 3/4(4) - b

1 = 3 - b

b = -2

now you have m and b so you can finish writing your equation.

y = mx + b

y = 3/4x - 2

I believe it is 56 degrees. that's the answer I put in and I got it right

Answer: True

The errors represent how far off the guess is to the true value. The points on the residual plot must be scattered randomly around 0, in both positive and negative regions. Ideally, the smaller the errors, the better the fit. So we want these errors to be as close to 0 as possible. This is why we try to minimize the sum of the squared error (SSE) when trying to find the linear regression equation. The r and r^2 value are related to this idea as well.

If we don't have randomly scattered errors, and some pattern shows up, then this means a linear equation is not a good fit. Another model such as a quadratic model may be the better option.

As for the "why" this works, try to think of a person throwing darts. Their accuracy isn't perfect so they'll likely miss on the left and right sides of the target. Stuff on the left is negative territory, while stuff on the right is positive. Each side is fairly equal assuming the thrower isn't biased in some way. That's why we have randomly scattered points in both regions. In the case of a regression line, that's where our guess goes while the actual data point is the observed value. The difference between the two is the error.

The equivalent of 17 km in yards to nearest whole number is 18,591 yards.

The given parameters;

To convert 17 km to yards, we find the equivalent of 1 kilometer in yards.

1 km = 1093.61 yards

Now, multiply the 17 km with its equivalent in yards as shown below;

[tex]= 17 \ km\times \frac{1093.61 \ yards}{1 \ km} \\\\= 18,591.37 \ yards\\\\\approx 18,591 \ yards[/tex]

Thus, the equivalent of 17 km in yards to nearest whole number is 18,591 yards.

Step-by-step explanation: absolute value will always be positive

Answer:

x=-5

Step-by-step explanation:

-3-(7x+5)+9x=x-8+3x+10

Distribute the -1 to the terms in parentheses.

-3-7x-5+9x=x-8+3x+10

Combine like terms on both sides.

-8+2x=4x+2

Add 8 to both sides.

2x=4x+10

Subtract 4x from both sides.

-2x=10

Divide both sides by -2

x=-5

Answer:

Step-by-step explanation:

To find the combined probability we will write as a fraction with the number of occurrences for the specified conditions.

Here, we have 16 marbles total (as 6 + 6 + 4 = 16) and we want to find the probabiliy of choosing either a red or blue marble out of the 16. There are 10 marbles that are either red or blue (as 16 - 6 = 10) so the fraction would be 10/16. However, we still need to get this simplest form.

[tex]\frac{10}{16} = \frac{5}{8}[/tex]

As we cannot simplify 5/8 any further, this is the final answer.

Answer:

the answer is 1760

Step-by-step explanation:

Answer:

Step-by-step explanation:

price paid    = regular price ( 1 + coupon in percent)

             $28 = regular price x (1.3)

regular price = $28 / 1.3

                     = $21.54

The regular price of the jeans is equal to $93.33.

Given the following data:

To calculate the regular price of the jeans:

Since Noah had a coupon for 30% off, it simply means that he would get a discount of 30% for any clothing he buys at his favorite clothing store. Thus, the cost price of the jean multiplied by 0.3 would give the amount of money to be paid by Noah, which is $28.

Mathematically, the selling price is given by:

[tex]28 = \frac{30}{100} \times C\\\\2800 =30C\\\\C=\frac{2800}{30}[/tex]

C = $93.33

Answer:

The graph of the f(x) will horizontal shift left by 3 when f(x) is replaced by f(x+3).

Step-by-step explanation:

We know that when we add a constant to the input of the parent function, we get a horizontal shift.

The direction of shifting depends upon the value of the added constantly. If the added constant is negative, the shift of the graph will be left and if the added constant is positive, the shift of the graph will be right.

For example, consider the function

f(x)

so adding [tex]3[/tex] in the put i.e. [tex]f(x+3)[/tex] would be a change on the inside of the function, giving a horizontal shift left by 3.

Therefore, the graph of the f(x) will horizontal shift left by 3 when f(x) is replaced by f(x+3).
