Simple interest formula: P=Irt Solve for t

1 answer:

7 0

The formula should be I=Prt but whatever

if you had I=Prt then divide both sides by Pr to get I/(Pr)=t

if you want to use P=Irt, divide both sides by Ir to get P/(Ir)=t

Hello, a Maths question if anyone knows what to do Solve: 6(x+4)=30

eduard

Answer:

x = 1

Step-by-step explanation:

6(x+4)=30 (divide both sides by 6)

(x+4) = 30/6

x+4 = 5 (subtract 4 from both sides)

x = 5 - 4

x = 1

Find the volume of a cube with side length 5

Leviafan [203]

It's easy to find the volume of a cube! The equation is:

l x w x h or Length x Width x Height.

Since a cube's sides are all the same size, we can use 5 for all 3 of these values.

5 x 5 x 5 = 125

So, the volume of this cube is 125!

You are working at a Silver Mountain Tea bottling plant! The bottles of iced tea are supposed to be filled with 12 ounces of liq

Ede4ka [16]

Answer: $(12.007\ , \ 12.033)$

Step-by-step explanation:

Given : Sample size : n= 36 , which is a large sample (n>30) so the test applied here is z-test.

Significance level : $\alpha: 1-0.95=0.05$

Using Standard normal table , Critical value : $z_{\alpha/2}=1.96$

Sample mean : $\overline{x}=12.02$

Standard deviation: $\sigma= 0.04$

The confidence interval for population means is given by :-

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

i.e. $12.02\pm(1.96)\dfrac{0.04}{\sqrt{36}}$

$\approx12.02\pm0.013=(12.02-0.013,\ 12.02+0.013)\\\\=(12.007\ , \ 12.033)$

Hence, the 95 percent confidence interval for the fill rate = $(12.007\ , \ 12.033)$
