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.
Unfortunately, you haven't shared the equations from which you're supposed to choose your answer.
But we can write our own.
When will the distance traveled by the 1st car = the distance traveled by the 2nd car?
55 miles + (55 mph)x = (60 mph)x
solve this for x: 55 miles = (60-55)x mph = 5 mph
x=11 hours
The two cars are the same distance from the starting point after 11 hours.
Answer:
The distance around the crater is 9415. If the crater is in the shape of a circle then this distance is the circumference of the circle. The circumference C and diameter D of a circle are related by the formula
C = PI * D
If you plug in 9415 for C and 22/7 for PI and solve for D you get
9415 = (22/7) * D
D = (7/22) * 9415 ~ 2995.7

Step-by-step explanation:
Y = x
y = -2/3x + 5
x = -2/3x + 5
x + 2/3x = 5
3/3x + 2/3x = 5
5/3x = 5
x = 5 * 3/5
x = 15/5 reduces to 3
y = x
y = 3
so ur answer is (3,3)
