For the top shape, x = 11, y = 10 and z = 14.
Start with the equation: 11y + 7y = 180 because those two angles are supplementary. Solving that will give you that y = 10.
The angle that is labelled 7y is therefore 70 degrees. We can write the following equation will the 5x because it is corresponding to the 70 degree angle.
5z = 70
z = 14
And we can also write and solve for the x, using the 70 degree angle.
70 + 10x = 180
10x = 110
x = 11
Answer:
First option,
Step-by-step explanation:
Simplify the fraction. To make the process of solving easier, we can multiply both the numerator and denominator by x and y to get rid of the fractions as seen below. This is because the variables in the denominators of the fractions will cancel out with either the matching x or y in the numerators.
Thus, the first option is correct.
Answer:
The correct option is C.
No. The sum of the relative frequencies is 95%, not 100%
Step-by-step explanation:
In a<u> relative frequency distribution</u>, the value assigned to each class is the proportion of the total data set that belongs in the class.
We have given the statement:
Suppose a newspaper surveys 250 adults in a nearby town and inquires about their cell phone carrier. The accompanying table summarizes the results. Does this table describe a relative frequency distribution
The correct option is C.
No. The sum of the relative frequencies is 95%, not 100%
