Rauol measured the height of 12 different plants in his garden in April. He measured them again in June. What is the difference
jasenka [17]

The question is incomplete. Here is the complete question.

Raoul measured the ehight of 12 different plants in his garden in April. He measured them again in June.

April Heights (in inches) 12 15 23 11 42 45 44 39 12 19 20 12

June Heights (in inches) 45 45 40 43 11 14 12 13 41 40 45 41

What is the difference between the mean height in April and the mean height in June?

Answer: The difference between means is 8.0

Step-by-step explanation: <u>Mean</u> is the average of a set of numbers.

It is calculated as:

\mu=\frac{\Sigma x}{n}

where

x is the numbers in the set

n is how many numbers are there in the set

For heights in April, the mean is:

\mu_{1}=\frac{12+15+23+11+42+45+44+39+12+19+20+12}{12}

μ₁ = 24.5

For heights in June, the mean os:

\mu_{2}=\frac{45+45+40+43+11+14+12+13+41+40+45+41}{12}

μ₂ = 32.5

The difference between means:

μ₂ - μ₁ = 32.5 - 24.5 = 8.0

The difference between the mean height in April and in June is 8.0 inches.

Help!! Please I’m stuck give [10pts]
pishuonlain [190]

Answer:

x = 18

Step-by-step explanation:

To solve this problem, we can use the exterior angle theorem, which means the measure of an exterior angle is the sum of its remote interior angles. In this case, this would mean:

x + 72 = 5x

Since this gives us an equation, we can just solve for x:

x + 72 = 5x

72 = 4x

x = 18

Which equation is represented by the table?
Fantom [35]
The answer is C.

(0, 3)

y = x + 3

3 = 0 + 3

3 = 3

(1, 4)

y = x + 3

4 = 1 + 3

4 = 4

(2, 5)

y = x + 3

5 = 2 + 3

5 = 5
