Answer: 2.6
Step-by-step explanation:
1. We know that A to C is 14
2. B to C is 11.4 so we're going to find the remainder to equal 14.
3. 14 minus11.4 which equals 2.6
4. AB is 2.6
A researcher interested in vocabulary development obtains a sample of twenty 3-year old children to participate in a research study. The average (i.e., mean) score for the group of 20 is an example of a(n)___________.
a) sample
b) statistic
c) population
d) parameter
Answer: b) statistic
Step-by-step explanation:
Population = A large groups of individuals sharing the same or similar characteristic by the point og study.Sample = It is a subset of population .Parameter = It is measure of characteristic in population.Statistic = It is measure of characteristic in sample.Since the average score was taken by the group of 20 which is nothing but the sample.
That means, the average score is an example of statistic.
Hence, the correct option is b) statistic .
The function f(x) = |x| is graphed over the interval [−6, 3].
Which translation of the graph has the domain [−3, 6]?
Answer: g(x)=lx-3l
Step-by-step explanation:
g(x) = |x − 3| is the translation of the graph has the domain [−3, 6]. Therefore, option D is the correct answer.
Given that, the function f(x) = |x| is graphed over the interval [−6, 3].

Why do you need to apply a force in order to get the box to move
Answer:
The reason one must apply a force to a box in order for the box to move is to overcome the friction generated by the box against the plane the box is sitting.
The box at rest has zero friction against the surface on which it sits. Once a force is applied, a box's movement is resisted by the friction created from contact with the surface.
In order for the box to move, one must generate more force than is being generated by the friction of the surface onto the box, allowing the box to move.

A toy company spends $1900 for factory expenses plus $11 per toy truck (t) to make each toy truck. The trucks (t) sell for $30 each. What is the equation in terms of (t).
Answer:
P(t) = 19t - 1900
Step-by-step explanation:
The factory expenses = $1900
Per toy expense = $11
The selling price of toy = $30
Now we have to convert it in the equation form. Use the below formula to convert these values in equation form.
Profit = Total revenue – total cost
Profit = TR – (variable cost + fixed cost)
Profit on truck = 30t – (11t + 1900)
Profit = 30t – 11t – 1900
P(t) = 19t - 1900

What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the question
Hank's pickup can travel 95 miles on 5 gallons of gas.
95 miles ⇒ 5 gallons of gas
76 miles ⇒ X
95X = 76 × 5
X = [tex]\frac{76(5)}{95}[/tex]
X = 4

Any real number works for x
==============================================
Work Shown:
[tex]6 - 2x - 1 = 4x+5 - 6x\\\\-2x+6 - 1 = 4x - 6x+5\\\\-2x+5 = -2x+5[/tex]
We get the same identical expression on both sides. So plugging any number in for x leads to getting the same number on both sides.
-----------
For instance, if x = 0,
[tex]-2x+5 = -2x+5\\\\-2(0)+5 = -2(0)+5\\\\5 = 5\\\\[/tex]
which is a true statement. The same happens when we plug x = 0 into the original equation
[tex]6 - 2x - 1 = 4x+5 - 6x\\\\6 - 2(0) - 1 = 4(0)+5 - 6(0)\\\\6 - 0 - 1 = 0+5 - 0\\\\5 = 5\\\\[/tex]

HELP!!!!!!! The square in the middle has an area of 1 square unit. What is the area of the entire rectangle in square units? Explain your reasoning.
Answer:
4 square units
Step-by-step explanation:
If you draw a vertical line down the middle of the square, you divide it into two triangles that are congruent to the smaller triangles shown in the figure. Hence each of those triangles has an area of 1/2 square unit.
After you have divided the square as above, you see that two smaller triangles are identical in area to the larger triangles. So, each of those has an area of 2(1/2) = 1 square unit.
Then the total of areas is ...
2 small triangles + square + 2 large triangles = 2(1/2) + 1 + 2(1) = 4
The area of the rectangle is 4 square units.

Anne and Nancy use a metal alloy that is 21.8% copper to make jewelry. How many ounces of a 13% alloy must be mixed with a 29% alloy to form 140 ounces of the desired 21.8% alloy?
Answer: 63.13%
Step-by-step explanation:
given data:
copper = 21.8%
0.13%x + 29%(140-x) = 21.8%(140)
open the brackets
0.13x + 40.6 - 0.29x = 30.5
collect like terms
0.13x - 0.29x = 30.5 - 40.6
–0.16x = –10.1
divide both sides by – 0.16
–0.16x / – 0.16 = –10.1 / –0.16
x = 63.13%

Slope intercept, show work I don't how to get it
Answer:
1) start with the point slope form y-y1=m(x-x1) and solve for y. y-8=2(x-6) so y-8=2x-12, add 8 to end up with y=2x-4. 2) start with slope intercept form and solve for b, then substitute that back in: y=mx + b, so 8=2(6)+b, 8=12+b, subtract 12 to get b=-4, therefore equation is y=2x-4.
