find the experimental probability and the theoretical probability.
The experimental probabilities of each outcome are given as follows:
Outcome of 1: 9/30 = 3/10.Outcome of 2: 5/30 = 1/6.Outcome of 3: 5/30 = 1/6.Outcome of 4: 7/30.Outcome of 5: 4/30 = 2/15.The theoretical probability of each outcome is given as follows:
1/5.
How to calculate a probability?A probability is calculated as the division of the desired number of outcomes by the total number of outcomes.
For the experimental probability, we consider the 30 trials in the table.
For the theoretical probability, we consider that each of the outcomes is equally as likely, hence the probability is given as follows:
p = 1/5.

Can someone please help me find the measure of the exterior angle.
Answer:
k = 140°
Step-by-step explanation:
The sum of the interior angles of any triangle = 180°.
64° + 76° + x = 180°
x = 40°
40° + k = 180° because they are supplementary angles
k = 140°
Answer:
k = 140°
Step-by-step explanation:
The sum of the interior angles of any triangle = 180°.
64° + 76° + x = 180°
x = 40°
40° + k = 180°
k = 140°
Find the value of x - this is circle segments.
Given:
Diagram of a circle and its two secant from an exterior point.
To find:
The value of x.
Solution:
We know that, If two secant are on a circle from an exterior point, then the products of measure of secants and measure of external segments of secants are equal.
Using the above property, we get
[tex](x+7)x=(2+2)2[/tex]
[tex]x^2+7x=(4)2[/tex]
[tex]x^2+7x=8[/tex]
[tex]x^2+7x-8=0[/tex]
Splitting the middle term, we get
[tex]x^2+8x-x-8=0[/tex]
[tex]x(x+8)-1(x+8)=0[/tex]
[tex](x+8)(x-1)=0[/tex]
Using zero product property, we get
[tex](x+8)=0[/tex] and [tex](x-1)=0[/tex]
[tex]x=-8[/tex] and [tex]x=1[/tex]
Side cannot be negative.
Therefore, the only possible value of x is 1.

At 78°F, a certain insect chirps at a rate of 106 times per minute, and at 81°F, they chirp 112 times per minute. Write an equation in slope-intercept form that represents the situation.
Answer:
y=2x-50
Step-by-step explanation:
[tex]m=\frac{y^2-y^1}{x^2-x^1} = \frac{112-106}{81-78} =\frac{6}{3} =2[/tex]
slope-intercept formula(substitute 81 for x, 112 for y, and 2 for m:
y=mx+b
112=2(81)+b
112=162+b
Then subtract 162 from both sides, and b=-50
Plug in all numbers into original equation
y=mx+b m=2 b= -50
So u get y=2x-50
Answer:
y = (1/2)x + 25 or y = 0.5x + 25

Please find the angles
Answer:
<1 = 50
<2 = 40
<3 = 90
<4 = 90
<5 = 40
<6 = 50
<7 = 130
Step-by-step explanation:
<5 + <6 = 90
40 + <6 = 90
<6 = 50
<5 = <2 because of vertical angles
<2 = 40
<6 = <1 because of vertical angles
<1 = 50
<7 = <4 + <5
<7 = 90 + 40
<7 = 130
Answer:
Solution given:
<4=90°[vertically opposite angle]
<2=<5=40°[vertically opposite angle]
<3=90°[right angle]
again
<1+<2=90°[right angle]
<1=90°-40°=50°
<1=50°
again
<5=40°[given]
<6=<1=50°[vertically opposite angle]
<6=50°
again
<7=<4+<5=90°+40°=130°

Hi, can someone help me finish this?
Answer:
Just B
Step-by-step explanation:
The two plots below show the heights of some sixth graders and some seventh graders:
Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot above the third mark, 1 dot above the fourth mark, 3 dots above the fifth mark and 1 dot above the sixth mark.
The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.8. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.)
1.5
2.2
3.0
4.6
Answer:
The number of times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders is:
3.0
In order to find the variability between the two sets we divide the mean absolute deviation of the first set of data by the mean absolute deviation of the second set of the data.
The MAD of first set of data is: 1.2
and MAD of second set of data is: 0.4
Hence, let n be the number of times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders.

Match the questions with the correct answers about the given box plot below
Answer:
1. D
2. E
3. B
4. C
5. A
5. F
Step-by-step explanation:
The median can be found at the line inside of the box, the heaviest weight would be found at the right end of the line, and the smallest weight would be found at the left, the interquartile range is the difference of one end of the box to the other, and the range is the difference of the largest number of the entire diagram, from the smallest number.
Hope this helps you!
Answer:
Florida: The weight range = 10
Tennessee: The interquartile range = 4
Tennesse: Median Weight = 76
Florida: Median Weight = 80
Florida: Weight of the heaviest child = 84
Tennesse: Weight of the smallest child = 71
Step-by-step explanation:
Florida: How to find the weight range
The range of a data set is the difference between the minimum and maximum. To find the range, calculate xn minus x1.
R = xn − x1
Therefore, the weight range in Florida is 10
Tennessee: How to find the interquartile range
To find the interquartile range (IQR), first, find the median (middle value) of the lower and upper half of the data set. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
71, 72, 73, 74, 75, 76, 77, 78, 79, 80
Q1 = 74
Q2 = 78
78 - 74 = 4
Therefore, the interquartile range in Tennesse is 4
Tennesse: Median Weight
The median x˜ is the data value separating the upper half of a data set from the lower half.
Arrange data values from lowest to the highest value
The median is the data value in the middle of the set
If there are 2 data values in the middle the median is the mean of those 2 values.
x˜ = 75.5
Therefore, the median weight of Tennesse is 76
Florida: Median Weight
The median x˜ is the data value separating the upper half of a data set from the lower half.
Arrange data values from lowest to the highest value
The median is the data value in the middle of the set
If there are 2 data values in the middle the median is the mean of those 2 values.
x˜ = 79
Therefore, the median weight of Florida is 80
Florida: Weight of the heaviest child
Since the smallest number in Florida is 84,
Therefore, the weight of the heaviest child in Florida is 84
Tennesse: Weight of the smallest child
Since the smallest number in Tennesse is 71,
Therefore, the weight of the smallest child in Tennesse is 71
