Step-by-step explanation:
A=B times H
Given: Parallelogram length = 11 cm triangle atop the parallelogram :
short leg = 7 cm : Right triangle inside the parallelogram :
long leg = 9cmArea of parallelogram =
base * heightA = 11cm * 9cmA = 99 cm²
Area of a triangle atop the parallelogram: A = ab/2A = (11cm * 7cm)/2A = 77 cm² / 2A = 38.5 cm²
Total area of the figure 99 cm² + 38.5 cm² = 137.5 cm²

The ratio of voters to nonvoters is 210 to 50.
Step-by-step explanation:
"product" means multiplication. the same as "times".
so,
135 = r×9
I'll do the first one:
Both novels.
Student 1 picks a novel. There are 3 novels out of 6 books total.
Now there are 5 books left.
Student 2 picks a novel. There are 2 novels out of 5 books since the other student took a novel.
To find the probability you would multiply the probability student 1 gets a novel and the probability student 2 gets a novel.
So the probability is 1/5. Or 20%
With the mean and range, we can estimate the weights of the smallest and largest animals in each group.
For cats the interval is [ 3.75kg, 4.25kg] and for dogs is [9.5kg, 54.5kg]
<h3>
Which conclusions can be made with the given information?</h3>
We know that the mean weight for cats is 4kg, and the range (difference between the largest value and smallest value) is 0.5kg.
- From that, we can conclude with some confidence (but not exactly), that the largest cat weights 4kg + 0.5kg/2 = 4.25kg
- And the smallest cat weights 4kg - 0.5kg/2 = 3.75kg
(Assuming a normal distribution).
Similar for the dogs, the mean weight is 32kg and the range is 45kg, then:
- The largest dog weights 32kg + 45kg/2 = 54.5kg
- The smallest dog weights 32kg - 45kg/2 = 9.5kg
(again, assuming a normal distribution).
