Answer:
You can use proportions by settling the ratio from the sample equal to the ratio from the population.
Explanation:
For Example is 3 out of 50 phones in a sample are defective, then an estimated 60 out of 1000 phones in a population are defective. this can be found by solving the proportion 3/50=x/1000 where x is the estimated number of defective phones in the population.
Step-by-step explanation:
So for this question just substitute the value and work out. I thought it it to the power of 2 as I can't tell from the question.
Answer:
k=2
Step-by-step explanation:
7[k+8]=70
First distribute the 7 into the k+8
7k+56=70
Then subtract the 56 on both sides since we want to isolate the variable
7k=14
Lastly divide each side by 7 to get the variable by itself and its value
k=2
We can check this by plugging 2 into the equation. We substitute for 2 in place of k.
7[2+8]=70
First do inside the brackets
7[10]=70
Next multiply
70=70
The equation is true so we know for sure that 2=k
48 inches is 4 feet.
36 inches is 3 feet.
The question is asking for the area in square feet of a rectangle that is 4 feet long by 3 feet wide. That area is the product of these dimensions:
(4 ft)×(3 ft) = 12 ft²
