Find the area of the figure

lana [24]

Answer:

Below

Step-by-step explanation:

First I found the area of the portion that extends off (if that makes sense??)

It is a triangle, so use A = bh/2

A = (2)(6) / 2

= 6 cm^2

Next I found the area of the rectangle using A = LW

A = (6)(3)

= 18 cm^2

Total area = 18 + 6

= 24 cm^2

Hope this helps! Best of luck <3

Each pound of fruit costs $4. Write an expression that shows the total cost of the fruit. Use the variable you identified in que

vovangra [49]

Answer:

$ $4f$

Step-by-step explanation:

Let's assume $f$ represents the number of pounds of fruit.

We need to multiply the number of pounds of fruit by the cost per pound.

This is $ $f * 4$ , or in a simpler form, $ $4f$ .

You measure 20 turtles' weights, and find they have a mean weight of 45 ounces. Assume the population standard deviation is 11.5

Naily [24]

Answer: the maximal margin of error associated with a 90% confidence interval for the true population mean turtle weight = 4.23

Step-by-step explanation:

Formula for margin of error : $E=\dfrac{z^*\times (Population\ standard\ deviation)}{\sqrt{Sample\ size}}$

, where z* = Critical z-value.

Given: population standard deviation = 11.5 ounces

Sample size = 20

Z value for 90% confidence level = 1.645

margin of error (E) = $\dfrac{1.645\times11.5}{\sqrt{20}}$

$\approx4.23$

Hence, the maximal margin of error associated with a 90% confidence interval for the true population mean turtle weight = 4.23
