9514 1404 393
Answer:
-26, -25
Step-by-step explanation:
The average of the two is their sum divided by 2: -51/2 = -25.5. The average of consecutive integers is halfway between them.
Hence, one is -26 and one is -25.

Determine the value of c that will result in a perfect square trinomial.
w^2+6w+ c =130+c
Answer:
The value of c that will result in a perfect square trinomial is (3)^2 or 9
The perfect square trinomial is: [tex](w+3)^2=139[/tex]
Step-by-step explanation:
We need to determine the value of c that will result in a perfect square trinomial.
[tex]w^2+6w+ c =130+c[/tex]
Perfect square trinomial are of form: [tex]a^2+2ab+b^2=(a+b)^2[/tex]
Now, the equation given is:
[tex]w^2+6w+ c =130+c[/tex]
Looking at the term 6w, we can write it as 2(w)(3)
We are given: a = w, 2ab = 2(w)(3) so, b will be: (3)^2
So, we will be adding (3)^2 on both sides
[tex]w^2+6w+ c=130+c\\w^2+2(w)(3)+ (3)^2 =130+(3)^2\\The\:left\:side\:becomes: a^2+2ab+b^2\\We\:can\:write\:it\:as: (a+b)^2\\We\:have\:a=w\: and\: b=3\\(w+3)^2=130+9\\(w+3)^2=139[/tex]
So, The value of c that will result in a perfect square trinomial is (3)^2 or 9
The perfect square trinomial is: [tex](w+3)^2=139[/tex]

Using a scale, or rate, of Inch per foot, calculate the room's dimensions for your drawing.
Answer:
Scaling is used to resize the dimension of a structure to fit the different platforms, like from structure to paper.
Step-by-step explanation:
To resize down-scale the dimension of a room, if the scale is 1/4 inches per foot, then the size of a 6x4 feet (width and length) room would be;
1/4 x 6 = 1.5 inches
1/4 x 4 = 1 inches
that is, 1.5 x 1 inch on paper when scaled down.

What are the solutions to the system of equations? {−x+y=4y+12=x2+x
Answer:Since -2 can not equal 0, there is no solution. The lines are parallel. It is an inconsistent system.
Step-by-step explanation:
The first step in solving a system of equations by substitution is solving one of the equations for one of the variables
x - y = 0 Equation 1
x - y + y = 0 +y Add y to each side
x = y Simplify
After solving an equation for one of the variables, substitute that value into the other equation. In this problem, I can substitute y for x.
x - y - 2 = 0 Equation 2
y - y - 2 = 0 Substitute the value of x from equation 1
0 - 2 = 0 Inverse Property of addition
-2 = 0 Identity Property of addition

Bob is doing a quality test on machine bolts. He tested 24 bolts that he randomly picked and found that 5 were defective Based on Bob's results, what is the expected number of bolts that will be defective if he tests 840 bolts?
Answer:
Mean of the binomial distribution
μ = 174.972 bolts
Step-by-step explanation:
Step(i):-
Given that Bob tested 24 bolts that he randomly picked and found that 5 were defective
The proportion of the defective item
[tex]p = \frac{x}{n} = \frac{5}{24} = 0.2083[/tex]
Step(ii):-
Let 'x' be a random variable in a binomial distribution
Mean of the binomial distribution
μ = np
μ = 840 ×0.280
μ = 174.972
Final answer:-
Mean of the binomial distribution μ = 174.972 bolts
Meg is packing a shipping conditier.
There is one section of the shipping container that has not yet been packed. The space available is in the shape of rectangular
prism that measures 2 feet by 3 feet by 33 feet.
She will pack as many boxes into the available space as possible. Each box is in the shape of a cube with side length 1 foot.
The space available in the shinning container and one of the boxes are shown below.
Answer:
[tex]Boxes= 198[/tex]
Step-by-step explanation:
This question has uncleared details towards the end. However, one can deduce that we need to calculate the amount of box the available space can contain.
We have the following given parameters.
Shipping Container
[tex]Dimension: 2ft\ by\ 3ft\ by\ 33ft[/tex]
The box
[tex]Dimension: 1ft\ by\ 1ft\ by\ 1ft[/tex]
First, we calculate the volume of the shipping container.
[tex]V_A = 2ft * 3ft * 33ft[/tex]
[tex]V_A = 198ft^3[/tex]
Next, we calculate the volume of the box.
[tex]V_B = 1ft * 1ft * 1ft[/tex]
[tex]V_B = 1ft^3[/tex]
The number of box is then calculated as:
[tex]Boxes= \frac{V_A}{V_B}[/tex]
[tex]Boxes= \frac{198ft^3}{1ft^3}[/tex]
[tex]Boxes= \frac{198}{1}[/tex]
[tex]Boxes= 198[/tex]
Hence:
198 boxes will occupy the empty space
1131 divided by 29 \
