Number of Green Candies in a Bag
A dot plot going from 10 to 15. 10 has 1 dot, 11 has 3 dots, 12 has 1 dot, 13 has 2 dots, 14 has 3 dots, and 15 has 3 dots.
The center is
.
Answer:
[tex]Median = 13[/tex]
Step-by-step explanation:
Given
See attachment for dot plot
Required
The center of data
This implies that, we calculate the median
From the attached plot,
[tex]n = 13[/tex] --- number of observation
So, the median is:
[tex]Median = \frac{n + 1}{2}[/tex]
[tex]Median = \frac{13 + 1}{2}[/tex]
[tex]Median = \frac{14}{2}[/tex]
[tex]Median = 7th[/tex]
The median is at the 7th position
At the 7th position, is 13
Hence:
[tex]Median = 13[/tex]
Answer:
i think it would be 13?
Step-by-step explanation:
just guessing but im pretty sure its 13

Christopher needs to buy wooden boardes to build a box that is 12 inches long, 6 inches wide, and 8 inches high. How many square inches of wooden boards is needed to build the box
Answer:
432 in²
Step-by-step explanation:
To Obtian the square inches of wooden boards required :
Area of box = 2(l * w) + 2(l * h) + 2(h * w)
Length = 12 ; width = 6 ; height = 8
Hence,
Area of box = 2(12 * 6) + 2(12 * 8) + 2(8 * 6)
Area of box = 2(72) + 2(96) + 2(48)
Area of box = 432 in²

2y+x=-15
y=2x
Answer: x = -3
Step-by-step explanation:
2y + x = -15
y = 2x
2y = 2(2x) = 4x
4x + x = -15
5x = -15
x = -3
A quality control manager samples 700 LED bulbs and finds defects in 8 of them. What is the probability that a bulb selected at random will have a defect?
Answer: 0.0114
Step-by-step explanation:
Since we are given the information that the quality control manager samples 700 LED bulbs and finds out that 8 bulbs have defects in them.
The probability that a bulb selected at random will have a defect will be calculated as follows:
= Number of defected bulbs / Total number of bulbs sampled
= 8/700
= 0.0114
Therefore, the probability is 0.0114.
Point R′ (−2, 8) is the image of point R (−2, 2). Which of the following algebraic representations could be used for that transformation?
Select one:
(x,y)→(−x,y)
(x,y)→(4x,4y)
(x,y)→(x,y+6)
(x,y)→(x+6,y)
Answer:
C) (x,y) → (x,y+6)
Step-by-step explanation:
As the x value stays the same after the transformation, we know that there can be no changes to the value x, automatically limiting the options to answer C.
The mathematical way to find the value y is changed by would be by setting up a small equation as follows:
[tex]8 = 2 + n[/tex], where n is some number that the y value is altered by.
Solving for n gives the value 6, proving that the translation must add 6 to the y value.
What is the slope of the line on the graph
Answer:
slope of the line(m) =(y2-y1)/(x2-x1)
or, m=(16-10)/(6-3)
or, m=6/3
So, m=2

Answer:
Number of flowers required = 1256
Step-by-step explanation:
Circumference of a circle is given by the formula,
Circumference = 2πr
Here, r = radius of the circle
For a circle with radius = 100 in.
Therefore, circumference = 2π(100)
= 200π
= 628.32 ft
Distance between each flower = 6 in
≈ [tex]\frac{6}{12}[/tex]
= 0.5 ft
Number of flowers = [tex]\frac{\text{Circumference}}{\text{Space between each flower}}[/tex]
= [tex]\frac{628.32}{0.5}[/tex]
= 1256.63
≈ 1256
Therefore, number of flowers required = 1256

Step-by-step explanation:
Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x overbarequals103.29, y overbarequals103.75, requals0.899, P-valueequals0.000, and ModifyingAbove y with caret equals negative 9.5 plus 1.1 x, where x represents the IQ score of the younger child. Find the best predicted value of ModifyingAbove y with caret given that the younger child has an IQ of 105? Use a significance level of 0.05.
Answer:
106
Step-by-step explanation:
Given :
Number of the set of siblings = 20
This 20 pair yields [tex]$\overline x$[/tex] = 103.29, [tex]$\overline y$[/tex] = 103.75, requals = 0.899, P-value = 0.000
Let x represents the IQ score of the younger child.
And y is the predicted value of Y(^).
So according to the question,
x = 105
and y = -9.5 + 1.1 x
Then,
y = -9.5 + 1.1 (105)
y = -9.5 + 115.5
y = 106
So the best predicted value of Y(^) is 106

What was Dimitri's mistake? He mixed up the coordinates of the ordered pair when Substituting it into the equations 7x+9y=-4 and 5x-2y=6
Answer:
He made a mistake in his calculations when simplifying 5x - 2y
Step-by-step explanation:
Given
The coordinate pair
[tex](x,y) = (2,-2)[/tex]
The equations
[tex]7x + 9y = ?[/tex]
[tex]5x - 2y = ?[/tex]
Dimitri's Solution
[tex]Equation\ 1: 7x + 9y = -4.[/tex]
[tex]7(2) + 9 (-2) = -4.[/tex]
[tex]14 + (-18) = -4.[/tex]
[tex]-4 = -4.[/tex]
[tex]Equation\ 2: 5x -2y = 6.[/tex]
[tex]5(2) - 2 (-2) = 6.[/tex]
[tex]10 - 4 = 6.[/tex]
[tex]6 = 6.[/tex]
Required
Identify Dimitri’s mistake
In the first equation, Dimitri made no mistake.
However, he made a mistake when simplifying the second equation.
We have:
[tex]5x - 2y[/tex]
and
[tex](x,y) = (2,-2)[/tex]
Substitute [tex]x = 2[/tex] and [tex]y = -2[/tex]
So, we have:
[tex]5(2) -2(-2)[/tex]
Open bracket
[tex]10 +4[/tex]
Finally, we have:

Claire had 4 1/6 feet of string. She used some string to hang out decorations. Now she has 1 5/6 feet of string left. How much string did claire use? Draw a model and solve.
Answer:
Length of string used by Claire = 7 / 3 feet
Step-by-step explanation:
Given:
Length of string Claire in starts = [tex]4\frac{1}{6}[/tex] feet
Length of string Claire in end = [tex]1\frac{5}{6}[/tex] feet
Find:
Length of string used by Claire
Computation:
Length of string Claire in starts = [tex]4\frac{1}{6}[/tex] feet = 25 / 6 feet
Length of string Claire in end = [tex]1\frac{5}{6}[/tex] feet = 11 / 6 feet
Length of string used by Claire = Length of string Claire in starts - Length of string Claire in end
Length of string used by Claire = [25 / 6] - [11 / 6]
BY taking LCM
Length of string used by Claire = [25 - 11] / 6
Length of string used by Claire = 14 / 6
Length of string used by Claire = 7 / 3 feet
