The answer to you’re question is 60
Yakvenalex [24]3 years ago
6 0

Answer:

60

Step-by-step explanation:

Because the diameter of this circle is 20 and the formula for the circumference (perimeter) of a circle is pi * the diameter, or πd, which, if π is 3, can be computed as 60.

A takeaway from this problem is that you should memorize basic equations like the circumference/area of a circle.

Help, please (single variable calculus)

Hi there!

\large\boxed{ 14.875}

Our interval is from 0 to 3, with 6 intervals. Thus:

3 ÷ 6 = 0.5, which is our width for each rectangle.

Since n = 6 and we are doing a right-riemann sum, the points we will be plugging in are:

0.5, 1, 1.5, 2, 2.5, 3

Evaluate:

(0.5 · f(0.5)) + (0.5 · f(1)) + (0.5 · f(1.5)) + (0.5 · f(2)) + (0.5 · f(2.5)) + (0.5 · f(3)) =

Simplify:

0.5( -2.75 + (-3) + (-.75) + 4 + 11.25 + 21) = 14.875

A 40-foot pipe is cut into three sections. The longest section is three times as long as the shortest, and the middle-sized sect
PtichkaEL [24]

Answer:

P=40

a + b + x = P

a = 3x    

b = x + 5

substitute for b & y

3x + (x+5) + x = 40

Step-by-step explanation:

longest section 1 = a

mid length section 2 = b

shortest section 3 = x

P=40

a + b + x = P

a = 3x    

b = x + 5

substitute for b & y

3x + (x+5) + x = 40

5x + 5 = 40

5x = 35

x = 7

b = 12

a = 21

1250 randomly chosen individuals from a certain population are tested for the presence of the HIV virus, and 20 are found to be
Harrizon [31]

Answer:

0.016

Step-by-step explanation:

To find the probability we have to Divide the number of events by the total number of possible outcomes. This will result in the probability of the single event.

Therefore, the formula of probability is

P(v) = \frac{no of events}{total possible outcomes}\\

In the given case,

P(v) = \frac{20}{1250}\\ P(v) = 0.016

Which is our required answer.
