The answer is 5.6 because 2+2+4+5+5+6+7+7+8+10=56
and 56/10=5.6
To find the mean<span>, add all the values together and divide by the number of values in the set. The result is your </span>mean<span>!
</span>Hope I helped:)

➷ Percentage = (amount / total) x 100
Substitute the values in:
Percentage = (27/50) x 100
Solve:
Percentage = 54%

Answer:
The slope is 3/2
Step-by-step explanation:
The first step would be to find two clear points on the graph. You cant really get an exact reading on points between values so you want to get ones that are right on the mark.
On your graph I can clearly see the points (30,60) and (50,90).
From here you just use the formula to find the slope. ((y2-y1)/x2-x1))
90-60=30
50-30=20
30/20 can then be reduced to 3/2.
Hope this made sense!
To investigate which of the choices satisfy the equation, substitute the values of the abscissas into the equation and solve for y. See if the value of y calculated is equal to the value of the ordinate of the point.
A. (7, -2) ; (2)(7) + 5y = 4 ; y = -2 EQUAL
B. (0, -1) ; (2)(0) + 5y = 4 ; y = 0.8 NOT EQUAL
C. (0, 1) ; <span>(2)(0) + 5y = 4 ; y = 0.8 NOT EQUAL
D. (3, -2) ; (2)(3) + 5y = 4 ; y = -0.4 NOT EQUAL
Thus, the answer is letter A. </span>
