Answer:
Let's see the first two points: (-7, 5) and (-5, 9)
The line passes these points has a form of: y = Mx + b
=> 5 = (-7)M + b
9 = (-5)M + b
Subtract the 1st equation from 2nd equation, we have:
4 = 2M
=> M = 2
Substitute M back into 1st equation:
=> 5 = (-7)*2 + b
=> b = 19
=> y = 2x + 19
or y - 5 = 2x + 14
or y - 5 = 2(x + 7)
=> Option A is correct
Hope this helps!

It is $7. Anything average 5 you need to round up
Answer:
y = 240sin(180πx)
Step-by-step explanation:
This the answer because a is represented by the amplitude, 240, and the frequency is equal to IbI/2pi. to solve for b, multiply the frequency by 2pi.
Answer: sigma is used for measuring Population Standard Deviation.
Step-by-step explanation:
The lower case Greek letter 'sigma' is denoted by the symbol ( ).
This symbol indicates the Population Standard Deviation of the data. Standard deviation means how much variation or dispersion is there in our data. Squaring of standard deviation gives us Variance which is denoted by the symbol .
Formula for Population Standard deviation ( ) is = ,
where = each value from our list of data
= Population mean of data
N = Number of observations in our data
Standard deviation can never be negative and it is very much sensitive to outliers in our data.
Answer:
P(red marble) = 6÷15
Step-by-step explanation:
First, we add all of it we get 15.
Now the probability of getting a red marble will be = number of favorable outcomes ÷ total out comes.
Here the favorable outcomes to red is 6,and the total outcome is 15.
So it is 6÷15.
Now we took one marble. And kept it away.
Now the total number of outcomes are 15-1=14
Now the favorable outcomes for green is 7,snd total outcomes are 14.
So the probability is 7÷14.
Remember don't subtract the one marble u took in every similar question. Do it only if it is told to keep away the first marble you took.
