this function is in the form of

y

=

m

x

+

q

with

m

=

3

,

q

=

0

so it's an straight line: ascending [

m

You measure 47 backpacks' weights, and find they have a mean weight of 79 ounces. Assume the population standard deviation is 13
ki77a [65]

Answer:

3.14

Step-by-step explanation:

Given that:

Mean weight (m) = 79 ounces

Population standard deviation (s) = 13.1

Sample size = 47

Maximal margin of error associated with 90% confidence interval.

The margin of error is given by:

Zcritical * (standard deviation / sqrt(sample size)

Z critical at 90% confidence interval = 1.645

Hence,

Zcritical * (standard deviation / sqrt(sample size)

1.645 * 13.1 / sqrt(47)

1.645 * (13.1 / 6.8556546)

1.645 * 1.9108313

Hence, the margin of error is :

3.1433174885

= 3.14

Let f(x)=x^2+2 and g(x)=1-3x Find each function value. f(g(-4))
yawa3891 [41]

Answer:

171

Step-by-step explanation:

First you plug -4 into the g(x) equation

g(-4)= 1-3(-4)

Use pemdas

g(-4)= 1+12

g(-4)= 13

Next you plug 13 into the f(x) equation

f(13)= 13^2 + 2

First you do 13^2=169

Add 2 and you get 171
