Answer:
A
Step-by-step explanation:
Point slope form:
y-y1=m(x-x1)
y+6=-2(x-4)
The answer is 73 because it is the only number that is showing the measurement of the bottom of the triangle. Don't get confused with 22 they put the line of 10 after 22 to trick your brain up but reading the problem again they are asking for the WHOLE triangle.
Hope this helps!
The answer is C, you need to add 5 to both sides
If you mean like a method to solve it fast here I have 1 solution I usually use;
3x2.7
3x.7=2.1
3x2=6
Then in the question there is 1 number behind the decimal point so the answer should have 1 number behind as well.
=8.1
Answer:
Step-by-step explanation:
Hello!
The mean is a measurement of central tendency that shows what is the most expected value of the variable. The standard deviation is a measurement of variability, it shows you how distant or dispersed are the values of a certain population or sample in regards to the value of the mean.
In this example the variable is X: score obtained on a math test.
It's mean is μ= 52 and its standard deviation is σ= 10
To know how many standard deviations away is a value of X concerning the mean you have to first subtract the mean to the value of X, X - μ, and then you have to divide it by σ:
(X - μ)/ σ
If X=76
(76 - 52)/ 10= 2.4
The score obtained by Andrea is 2.4σ away from the mean.
I hope it helps!
