Given points F(3,1), G(5,2) H(2,4), and J(1,6)
Karo-lina-s [1.5K]

The slopes of perpendicular lines are opposite reciprocals

The true statement is that segments FG and HJ are perpendicular

<h3>How to determine the relationship between the segments</h3>

The coordinates of the points are given as:

F = (3,1)

G = (5,2)

H = (2,4)

J = (1,6)

Start by calculating the slopes of FG and HJ using the following slope formula

m = \frac{y_2 -y_1}{x_2 -x_1}

So, we have:

FG = \frac{2 -1}{5 -3}

FG = \frac{1}{2}

Also, we have:

HJ = \frac{6 - 4}{1 - 2}

HJ = \frac{2}{-1}

HJ = -2

To determine the relationship, we make use of the following highlights

  • Parallel lines have the same slope
  • The slopes of perpendicular lines are opposite reciprocals

From the computation above, we have:

  • The slopes of both lines are not equal
  • The slopes are opposite reciprocals i.e. 2 = -1(-1/2)

Hence, segment FG and HJ are perpendicular

You are given the following data, where X1 (final percentage in history class) and X2 (number of absences) are used to predict Y
vaieri [72.5K]

Answer:

Step-by-step explanation:

Hello!

Given the variables

Y: standardized history test score in third grade.

X₁: final percentage in history class.

X₂: number of absences per student.

<em>Determine the following multiple regression values.</em>

I've estimated the multiple regression equation using statistics software:

^Y= a + b₁X₁ + b₂X₂

a= 118.68

b₁= 3.61

b₂= -3.61

^Y= 118.68 + 3.61X₁ - 3.61X₂

ANOVA Regression model:

Sum of Square:

SS regression: 25653.86

SS Total: 36819.23

F-ratio: 11.49

p-value: 0.0026

Se²= MMError= 1116.54

Hypothesis for the number of absences:

H₀: β₂=0

H₁: β₂≠0

Assuming α:0.05

p-value: 0.4645

The p-value is greater than the significance level, the decision is to not reject the null hypothesis. Then at 5% significance level, there is no evidence to reject the null hypothesis. You can conclude that there is no modification of the test score every time the number of absences increases one unit.

I hope this helps!

How do you write an exponential equation for this problem
Serhud [2]

Let's think about the information in the problem. The problem tells us a few key points:

  • The number of rabbits grows exponentially
  • We start with 20 rabbits (t = 0, a = 20)
  • After 6 months (t = 6), we have 100 rabbits (a = 100)

Since we know we are going to be working with an exponential model, we can start with a base exponential model:

a = P \cdot r^t

  • P is the principal, or starting amount
  • r is the growth/decay rate (in this case, growth)
  • t is the number of months
  • a is the number of rabbits

Based on the information in the problem, we can create two equations:

20 = P \cdot r^0 = P

100 = P \cdot r^6


The first equation tells us that P = 20, or that we start with 20 rabbits.  Thus, we can change the second equation to:

100 = 20 \cdot r^6

5 = r^6


Now, we don't know r, but we want to, so let's solve for it.

5 = r^6

r = \sqrt[6]{5}


Now, the problem is asking us how many rabbits we are going to have after one year (t = 12), so let's find that:

a = 20 \cdot (\sqrt[6]{5})^{12}

a = 20 \cdot (5^{\frac{1}{6}})^{12}

a = 20 \cdot 5^2

a = 500


After one year, we will have 500 rabbits.
