thanks for anyone who helped <3 ​

Answers

Answer:

-1 C

Step-by-step explanation:

Mean = Average

To find the mean simply add all the values and then divide that by the number of given values

So first add the 4 values together

1.5 + -2.6 + -3.4 + .5 = -4

Then divide the sum by the number of values ( there are 4 values )

-4 / 4 = -1

The mean temperature is -1

Answers

Answer:

120 fluid ounces

Step-by-step explanation:

1 cup = 8 fluid oz

Multiply 15 on both sides (since there is 3 pitchers and each is 5 cups, so 3 * 5 = 15 cups in total for all 3 pitchers) and we get 15 cups = 120 fluid oz.

So that's our answer

A cell phone tower casts an 80-foot shadow. At the same time, a 6-foot fence
post casts a shadow of 4 feet. What is the height of the tower?

Answers

The height of the tower is 120 feet

How to determine the height of the tower?

The given parameters can be represented using the following ratio

Ratio = Height : Shadow

So, we have:

Tower : 80 ft = 6 ft : 4 ft

Express as fraction

Tower/80 = 6/4

Multiply both sides by 80

Tower = 120 feet

Hence, the height of the tower is 120 feet
