Directions: Solve <br> I think you cross multiply but I'm not really sure where to go from there.
Vlada [557]
I'm fairly sure they want you to cross multiply then graph. This will give you 'zeroes' which are solutions for x
if you graph (4x^3+3x^2)= z it'll give you a zero at -0.75 which means x= -3/4

A forestry researcher wants to estimate the average height of trees in a forest near Atlanta, Georgia. She takes a random sample
marusya05 [52]

Answer:

The margin of error for her confdence interval is of 0.3757.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 18 - 1 = 17

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.99}{2} = 0.995. So we have T = 2.8982

The margin of error is:

M = T\frac{s}{\sqrt{n}}

In which s is the standard deviation of the sample and n is the size of the sample.

Standard deviation of 0.55 meters.

This means that s = 0.55

What is the margin of error for her 99% confidence interval?

M = T\frac{s}{\sqrt{n}}

M = 2.8982\frac{0.55}{\sqrt{18}}

M = 0.3757

The margin of error for her confdence interval is of 0.3757.

Work out how many litres of water she saves by having a shower instead of a bath
Ber [7]
Water used for shower = 10.6 x 7 = 74.2 liters

Water used for bath = 35 x 120 x 40 = 168 000 cm³ = 168 liters

Difference = 168 - 74.2 = 93.8 liters.

Answer: She saved 93.8 liters of water by showering instead of taking a bath.
