Find the equation of the linear function represented by the table below in slope-intercept form.
x y
-1 8
2 -1
5 -10
8 -19

Answers

Answer 1

Answer:

y = -x -3

Step-by-step explanation:

y value is decreasing which means negative slope

you can use slope formula to find slope

(y2-y1)/(x2-x1) = m

(-4-(-2))/(1-(-1)) = -1

m = -1

you can find y -intercept by plugging in slope and one coordinate into y=mx+b

-2 = -1(-1) + b

b = -3

Silas had 3 times as much money as Raja. Silas spent $84 of his money to buy a birthday gift for his grandma while Raja was awarded $42 for winning a competition. In the end, they had the same amount of money. How much did they have altogether at first?

Answers

Answer:

Total money they had at first $252.

Step-by-step explanation:

Let,

x be the amount Silas had originally

y be the amount Raja had originally

According to given statement;

x = 3y     Eqn 1

x - 84 = y + 42    Eqn 2

Putting x=3y in Eqn 2

3y - 84 = y + 42

3y - y = 42 + 84

2y = 126

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{126}{2}\\y=63[/tex]

Putting y = 63 in Eqn 1

x = 3(63)

x = 189

Total money they originally had = 189 + 63 = $252

Hence,

Total money they had at first $252.

measured in inches. The bulb is located at the focus. How far is the bulb from the

Vertex of the cross section?

Answers

Answer:

[tex]p=1/2\ or\ 0.5\ inches[/tex]

Step-by-step explanation:

From the question we are told that

Equation of cross section is [tex]y+5= \frac{1}{2x^2}[/tex]

Generally the equation can be rewritten mathematically as

  [tex]y+5= \frac{1}{2}x^2[/tex]

  [tex]x^2=(y+5)2[/tex]

  [tex](x-0)^2=(y-(-5))2[/tex]

Generally the equation of a parabola with vertical axis is mathematically given by

[tex](x - h)2 = 4p(y - k)[/tex]

Therefore  comparing equations

[tex](x-0)^2=(y-(-5))2[/tex]

[tex]4p=2[/tex]

[tex]p=2/4[/tex]

The distance from the bulb to the vertex of the cross section is given by

[tex]p=1/2\ or\ 0.5\ inches[/tex]

How to solve system of two equations:

First of all, we should get one variable in terms of other variable in one equation and substitute this variable in another equation. And solving that we get two variables value.

If you have two different equations with the same two unknowns in each, you can solve for both unknowns. There are three common methods for solving: addition/subtraction, substitution, and graphing.

Here,

let's consider price of hot dogs = x and price of hamburgers = y

then, 164x + 74y = $706 --- ( 1 )

and 256x + 61y = $884 --- ( 2 )

Now,  from eq - 1 we get x = ($706 - 74y) / 164

Substitute this x value in eq - 2,

256($706 - 74y)/164 + 61y = $884

=> $706*256 - 74y*256 + 61y*164 = $884 * 164

=> 180,736-8940y = 144,976

=> 180,736 - 144,976 = 8940y

=> 35,760/8940 = y

=> y = $4.

By substituting in eq - (1) we get x = $2.5

So, The price of hot dog = $2.5

4.A board is 7 3/4 feet in length. How many full sizes pieces of board 1 1/3 feet in length can a carpenter cut from that board of wood

Answers

Answer:

5 full pieces

Step-by-step explanation:

Given

[tex]Board\ Length = 7\frac{3}{4}ft[/tex]

[tex]Pieces = 1\frac{1}{3}ft[/tex]

Required

Determine the number of pieces that can be cut from the board

This is calculated by dividing the board length by the length of each piece.

[tex]Number = \frac{Board\ Length}{Pieces}[/tex]

[tex]Number = 7\frac{3}{4} / 1\frac{1}{3}[/tex]

Convert to improper fractions

[tex]Number = \frac{31}{4} / \frac{4}{3}[/tex]

Change / to *

[tex]Number = \frac{31}{4} * \frac{3}{4}[/tex]

[tex]Number = \frac{31*3}{4*4}[/tex]

[tex]Number = \frac{93}{16}[/tex]

[tex]Number = 5.8125[/tex]

Round down to discard the decimal parts

[tex]Number = 5[/tex]

Hence, the carpenter can cut full-sized 5 pieces

A manufacturing company uses two different machines, A and B, each of which produces a certain item part. The number of defective parts produced by each machine is about 1 percent. Suppose two independent random samples, each of size 100, are selected, where one is a sample of parts produced by machine A and the other is a sample of parts produced by machine B. Which of the following is true about the sampling distribution of the difference in the sample proportions of defective parts?
A The mean is 0 and the distribution is approximately normal
B The mean is 0 and the distribution will not be approximately normal
C The mean is 0.01 and the distribution is approximately normal
D The mean is 0.01 and the distribution will not be approximately normal.
Ε The mean is 1 and the distribution is approximately normal.

Answers

Answer:

B: The mean is 0 and the distribution will not be approximately normal

Step-by-step explanation:

It is true that the mean is 0 because it is the difference in the population proportions, 0.01−0.01. However, normality cannot be assumed because the sample sizes are not large enough.

The sample distribution is defined as the probability distribution of a given sample based on statistics.

The correct option is (a).

Given:

The defective parts produced by each machine is 1%.

The sample Size is 100.

Calculate the proportion of the defective parts.

[tex]\dfrac{1}{100}=0.01[/tex]

Thus, the mean of each machine is 0.01.

Now, the mean difference between both machine is 0 and proportion will be normally distributed.

What is the area of the triangle?

Answers

Answer:

[tex]10\:\mathrm{units^2}[/tex]

Step-by-step explanation:

The area of a triangle can be given as [tex]\frac{1}{2}\cdot b \cdot h[/tex]. Notice that a base of the triangle is given as 4 units, and the height is marked as 5 units. We know that the segment marked as 5 units is the height of the triangle because it forms a [tex]90^{\circ}[/tex] with the segment marked as 4 units and meets a vertex of the triangle.

Therefore, the area of the triangle is:

[tex]\frac{1}{2}\cdot 4 \cdot 5 = \fbox{$10$}[/tex].
