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.

Answer:
A times table is a list of multiples of a number. For instance, if we want to work out the times table for 2, we start with 2 and then add 2 in each step. The answer obtained in every step is a multiple of 2 and is known as multiplication fact. We can find out the times table of other numbers also.
True or false: In order to fill this figure with unit cubes, you would need to fill in 7 cubes in length, 10 cubes in height, and 3 cubes in width. Then, you would fill the rest of the space with cubes.
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°

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

Explain why you divide by 2 for triangles and why you divide by 3 for pyramids
Answer:
triangles are half a rectangle/square. So thats why you divide by 2. diving by 2 is also multiply by 1/2.
pyramids are in 3 dimensions, so since they are like half, but in three dimensions, you divide by 3, in other words multiply by 1/3.

QUESTION 2
PLEASE HELP MEEEEEEE
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.

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.
