Answer:

4. y = 8 - x

Step-by-step explanation:

The question asks for which function is the ordered pair not a solution?

We need to substitute the ordered pair (4, 12) into x and y.

1. 12 = 3(4) (correct)

2. 12 = 16 - 4 (correct)

3. 12 = 4 + 8 (correct)

4. 12 = 8 - 4 (incorrect)

Therefore, the solution to your question is option 4.

Help find out what the x is please

Answer:

x=4

Step-by-step explanation:

First you want to add 8.8 to 7.2 and get 16 because you want to get x alone

Next divide divide 4x on both sides so 4x/4x cross out and left with just x. 16/4 =4

x=4

Hope this helps!

The area of a square mat is 125 square inches. The best approximation of its length is inches. If the length of each side is inc
gtnhenbr [62]
The area of a square is simply the side length squared and we are given that the area is 125 so:

s^2=125

s=√125

s=5√5

Now using the area equation again, and adding 1 inch to s we have:

A=(s+1)^2, and using s found above we have:

A=(5√5+1)^2

A=125+10√5+1

A=126+10√5 in^2

A≈148.36 in^2  (to nearest hundredth of a square inch)

Sixty-five % of the spectators at the basketball game are male and there are 280 female spectators.
notsponge [240]
A). Simply, subtract 100 percent minus 65 percent, which gives you the answer 35 percent.

b). So, to find the total number you add 280 plus 65 percent, which gives you the answer, 462.

c). To find this, simply subtract 462 minus 280, which gives you the answer, 182.

Hope this helps!

The mean of a data set is equal to 10 and its standard deviation is equal to 1. If we add 5 to each data value, then the mean an
andrey2020 [161]
Let
S = sum of the data values
n = number of data values

The mean M is equal to 
M = S/n
since you add up the values and divide by n. We don't need to know what S or n are. 

If we add 5 to each data value, then we're adding on n copies of 5, or 5n

The new mean N is

N = (S+5n)/(n)
N = (S/n) + (5n/n)
N = M + 5

The new mean is a result of taking the old mean M and adding on 5

So,
N = M+5
N = 10+5
N = 15

The standard deviation will remain the same because each data value hasn't moved in relation to one another. Every data value has been shifted up the same amount. For instance if A and B are two points in this data set, then A+5 and B+5 will be the same distance away. Apply this logic to any number of data values. While standard deviation isn't that simple, it still has a loose connection to "distance" of the values, or how spread out they are. 


So that's why the final answer is choice C)
