A survey found that 3 out of 7 people in a community job on a regular basis. If there are 3150 people in the community, What is the reasonable prediction for the number of people who would jog regularly?

Answers

The requried reasonable prediction for the number of people who would jog regularly in the community is 1350.

What is proportionality?

Proportionality is the relationship between two or more sets of values, and it describes how these values are related to each other.

If 3 out of 7 people jog on a regular basis, then the fraction of people in the community who jog on a regular basis is:

3/7

To predict the number of people who would jog regularly in the community, we can multiply this fraction by the total number of people in the community:

(3/7) * 3150 = 1350

Therefore, a reasonable prediction for the number of people who would jog regularly in the community is 1350.

so 3150÷7=450 and then multiply 450×3= 1350. So 1350 people who jog regularly

Jen motorboat travels at a speed of 13mph in still water. Booth River flows at a speed of 3mph. How long will it take Jen to travel 11 mi upstream? 11mi downstream

Answers

Answer:

Upstream 1.1 hours and down stream 0.6875 hours.

Step-by-step explanation:

Jen motorboat travels at a speed of 13 mph in still water.

Now, the speed of river flows is 3 mph.

Therefore, the upstream speed of the boat is (13 - 3) = 10 mph and the downstream speed of the boat will be (13 + 3) = 16 mph.

Therefore, to travel 11 miles upstream Jen will take (11)/(10) = 1.1 hours.

And to travel 11 miles down stream Jen will take (11)/(16) = 0.6875 hours. (Answer)

How to find circumference of a circle​

Answer:

C=2πr

Step-by-step explanation:

The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle.

If a circle has a diameter of 4, its circumference is 3.14*4=12.56.

If you know the radius, the diameter is twice as large.

Answer:

the formula is C = 2(pi)r
