Hello there! I think it is a) 59%. So what I did is add all the numbers 51, 23, and 12 all together. So then I did 100/86= 1.162279068767. Then I did 1.162279068767*51= 59%(approximately).(That is only for the frequently!)

For both of them together it would be 86%( I rounded) So I did 1.162279068767*23. Then I add the 59%+26%= 86. That is how I got the answer.

I hope it helps.

V = Ah

where:

V = Volume of prism

A = Area of uniform cross-section or base of prism = 96 inches^2

h = Perpendicular height of prism = 9 inches

Substitute the values given in the question into the formula.

V = 96 × 9

V = 864 inches^3

denis-greek [22]

Answer:

Step-by-step explanation:

Given:

C_{(x)}=-0.00001x^{2}-0.02x+49

for x≤1400; N = 5

So, Δx = \frac{1400-0}{5} =280\\\\\int\limits^{1400}_0 {C(x)} \, dx=∑C(a + nΔx).Δx

=C(0)Δx + C(280)Δx + C(560)Δx + C(840)Δx + C(1120)Δx

= Δx[C(0) + C(280) + C(560) + C(840) + C(1120)]

= 280[49 + 42.616 + 34.664 + 25.144 + 14.056]

=280[165.48]

=46334 approx

svet-max [94.6K]

Answer:

$8 ; 66 cents

Step-by-step explanation:

Given that:

Worth of penny, dimes and Nickel in cents and dollars

Nickel, n = 5 cents = $0.05

Dimes, d = 10 cent = $0.1

Penny, p = 1 cent = $0.01

Multiplying the number of each coin with its respective value ;

386(0.01) + 58(0.05) + 19(0.1)

$3.86 + $2.9 + $1.9

= $8.66

Changing it to dollar ,

$8.66 dollars = 8 dollars ;

$0.66 = 66 cents

This is called as sampling error or sampling variability. Sampling error is the variability that happens because the value of a sample statistic varies from sample to sample. Sampling error is acquired when a population is estimated from a subset, or sample.
