 $90 is a good estimation because 27 is almost 30 and 30 x 3 is 90

Answer:

- 1

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ - 5, 6 ] , then

f(b) = f(6) = 6² - 2(6) - 5 = 36 - 12 - 5 = 19

f(a) = f(- 5) = (- 5)² - 2(- 5) - 5 = 25 + 10 - 5 = 30

Then

average rate of change = \frac{19-30}{6-(-5)} = \frac{-11}{6+5} = \frac{-11}{11} = - 1

What the solution set of the inequality 15y - 9 &lt; 36
Alika [10]

15y < 45

15y ÷ 15 < 45 ÷ 15

y < 3

He goodness of fit is measured by χ2. This statistic measures the amounts by which the observed values differ from their respect
Murrr4er [49]

Answer:

Step-by-step explanation:

Hello!

Table is attached.

1) Purple stem/short petals.

(o-e)= 220-225= -5

(o-e)²= (-5)²= 25

(o-e)²/e= 25/225= 1/9

2) Green stem/short petals

(o-e)= 210-225= -15

(o-e)²= (-15)²= 225

(o-e)²/e= 225/225= 1

3) Purple stem/ long petals

(o-e)= 231-225= 6

(o-e)²= (6)²= 36

(o-e)²/e= 36/225= 4/25

4) Green stem/ long petals

(o-e)= 239-225= 14

(o-e)²= (14)²= 196

(o-e)²/e= 196/225 (≅ 0.871)

To reach the statistic value you have to add the four values obtained in the last row:

X²= 1/9+1+4/25+196/225= 482/225≅ 2.142

I hope you have a SUPER day!

How much money must be deposited to T
Contact [7]

Answer:

First, converting R percent to r a decimal

r = R/100 = 5.5%/100 = 0.055 per year.

Putting time into years for simplicity,

6 months / 12 months/year = 0.5 years.

Solving our equation:

A = 200(1 + (0.055 × 0.5)) = 205.5

A = $205.50
