A cylindrical test tube holds 6π cm of liquid when filled to the 6cm mark what is the diameter of the test tube to the nearest h

DanielleElmas [232]

Answer:

2cm

Step-by-step explanation:

Given data

Capacity/volume of liquid held= 6π cm^3

Height= 6cm

Required

The diameter d of the tube

let us apply the expression for the volume of cylinder

V=πr^2h

6π=πr^2*6

6=r^2*6

r^2= 6/6

r^2=1

r= √1

r=1cm

Hence the diameter d = 2r= 2*1= 2cm

What is the sum of an infinite geometric series if a1 = 144 and r = 1⁄4?

Brilliant_brown [7]

Answer:

Step-by-step explanation:

The sum to infinity of a geometric sequence is

sum to infinity = $\frac{a_{1} }{1-r}$

here $a_{1}$ = 144 and r = $\frac{1}{4}$ , hence

sum = $\frac{144}{1-\frac{1}{4} }$

= $\frac{144}{\frac{3}{4} }$

= $\frac{144(4)}{3}$ = 192 → D

Customers are used to evaluate preliminary product designs. In the past, 95% of highly successful products received good reviews

maks197457 [2]

Answer:

Step-by-step explanation:

The given information can be tabulated as follows.

Success type High Moderate Low Total

0.40 0.35 0.25 1

Good reviews 0.95 0.60 0.10

Combined prob 0.4*0.95 0.35*0.6 0.25*0.1

0.38 0.21 0.025 0.6125

A) the probability that a product attains a good review

=Prob it it successful and gets good review + Prob it is moderate successful and gets good review +Prob it it low successful and gets good review

= 0.6125

B) If a new design attains a good review, the probability that it will be a highly successful product= $\frac{0.38}{0.6125} \\=0.6204$

C) Prob that does not attain a good review =(0.40*0.05)+0.35(0.4) +(0.25)*0.9

= 0.385

Prob for successful not getting good review = 0.40(0.05) = 0.02

Reqd prob = $\frac{0.02}{0.385} \\=0.05195$
