Answer:

-8x(2x - 9)

Step-by-step explanation:

-16x² + 72x

GCF = 8x

8x(16x² / 8x, -7x/8x)

-8x(2x - 9)

hope this helps!!

Find the Exponential Regression using the table. Write the initial amount, common ratio, and equation for the table.
Triss [41]

Answer:

Initial temperature;

432.76

Common ratio;

-0.067

Equation;

y=432.76e^{-0.067x}

Step-by-step explanation:

In this scenario, the time in minutes represents the independent variable x while the temperature of the pizza represents the dependent variable y.

The analysis is performed in Ms. Excel. The first step is to obtain a scatter plot of the data then finally inserting an exponential trend line to obtain the required equation.

The Ms. Excel output is shown in the attachment below. To obtain the initial temperature we substitute x = 0 in the equation. On the other hand, the common ratio is the exponent in the equation.

find the standard deviation for this data set 9, 15, 13, 9, 15 round your answer to the nearest tenth
KatRina [158]

Answer:

  • 3.0

Step-by-step explanation:

Sample standard deviation is found by steps below.

<u>Find the mean:</u>

  • μ = (9 + 15 + 13 + 9 + 15)/5 = 12.2

<u>Find deviations from the mean and their squares:</u>

  • 9 - 12.2 = - 3.2 ⇒ (-3.2)² = 10.24
  • 15 - 12.2 = 2.8 ⇒ 2.8² = 7.84
  • 13 - 12.2 = 0.8 ⇒ 0.8² = 0.64
  • 9 - 12.2 = - 3.2 ⇒ (-3.2)² = 10.24
  • 15 - 12.2 = 2.8 ⇒ 2.8² = 7.84

<u>Sum the squares:</u>

  • 10.24*2 + 7.84*2 + 0.64 = 36.8

<u>Divide by N - 1 (N - number of samples):</u>

  • 36.8/(5 - 1) = 9.2

<u>Square root is the sample standard deviation:</u>

  • σ = √9.2 = 3.0 (rounded)
