Taylor has a bag containing 15 counters. The table below shows the number of counters of each color in the bag. As a part of a probability experiment for science club, Taylor randomly picks a counter from the bag then replaces it. She repeats this 300 times.
Part A
Taylor randomly picks a counter out of the bag. What is the probability that it will be red?
Show your work and explain your answer.
Part B
Predict the number of times out of 300 Taylor will pick a red counter.
Answers
Answer:
part a. she has an 8 out of the 15 counters chance at getting red. part b. she has a chance of 262 times out of the 300 to get red
Step-by-step explanation:
i hope this helps and i'm sorry if it's wrong have a lovely day
The probability that it will be red is 8/15.
The number of times out of 300 Taylor will pick a red counter is 160.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
We have,
Taylor has a bag containing 15 counters.
First, the probability that it will be red
= 8/15
Now, if she repeats 300 times then
= 8/15 x 300
= 8 x 20
= 160

The answers to the questions are given below.
What is a expression? What is a mathematical equation? What is the volume of a cube and a prism?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. The volume of a cube is - [V] = a x a x awhere [a] is side length of cube.
The volume of a prism is -[V] = [h] × [w] × [L]where [h] is prism height, [w] is its width, and [L] is its length.
We have the question as shown in the figure.
Cube with side length (1/5) :
Volume = (1/5 x 1/5 x 1/5) = 1/125 cm³
Prism of dimensions (L = 1/5, B = 2/5, H = 3/5) :
Volume = (1/5 x 2/5 x 3/5) = 6/125 cm³
Cube with side length (2/5) :
Volume = (2/5 x 2/5 x 2/5) = 8/125 cm³
Prism of dimensions (L = 3/5, B = 4/5, H = 3/5) :
Volume = (3/5 x 4/5 x 3/5) = 36/125 cm³

For a science project, Chase recorded the amount of rainfall for 6 weeks. The line plot shows the amounts of rainfall he recorded. How many inches of rainfall were recorded?
Answers
Answer: B
Step-by-step explanation:
To answer this , we need to make a list of all the fractions represented with the dots . each dot stands for 1 of whatever fraction is given. for example, there are 2 dots on 3/8 . That means each dot=3/8
3/8, 3/8, 4/8, 5/8, 7/8.
Step 2: Add them up (because we want to find the total)
3/8+3/8+4/8+5/8+7/8= 6/8+4/8+5/8+7/8= 22/8= 2 6/8= 2 3/4
2 3/4 , or 2 6/8 is the answer; it's all the rain that was recorded .
Line plot shows the amounts of rainfall is equals to [tex]2\frac{6}{8}[/tex] inches.
What is line plot?" Line plot is defined as the representation of the data using point on the number line."
According to the question,
Number of weeks for which rainfall is recorded = 6
Data represents on the line plot = [tex]0, \frac{3}{8} ,\frac{3}{8}, \frac{4}{8}, \frac{5}{8}, \frac{7}{8}[/tex]
Total amount of rainfall recorded on line plot in inches
= [tex]0+\frac{3}{8} +\frac{3}{8}+\frac{4}{8}+\frac{5}{8}+ \frac{7}{8}[/tex]
= [tex]\frac{22}{8}[/tex]
= [tex]2\frac{6}{8}[/tex] inches
Hence, Option(B) is the correct answer.

A cone has a slant height of 7.5cm and a radius of 4.5 cm. What is the volume of the cone?
Answers
Now
volume:-
1/3πr²h1/3π(4.5)²(6)π(20.25)(2)40.5πcm³Answer:
Volume of cone = 127.17 cm³Step-by-step explanation:
In the question we are given ,
Slant height = 7.5 cmRadius = 4.5 cmAnd we are asked to find the volume of cone. We know that ,
[tex] \red{\boxed{ \rm{Volume \: of \: cone = \frac{1}{3} \pi r {}^{2}h }}}[/tex]
Where ,
π = 3.14r = 4.5 cmh = Not givenSo , for finding volume of cone we must have to find the height of cone using slant height formula i.e. ,
[tex] \green{\boxed{ \sf{l {}^{2} = h {}^{2} + r {}^{2} }}}[/tex]
Where ,
l = slant heighth = heightr = radiusNow , substituting values :
[tex] \hookrightarrow \: 7.5 {}^{2} = h {}^{2} + 4.5 {}^{2} [/tex]
Transposing 4.5 to left hand side :
[tex] \hookrightarrow \: 7.5 {}^{2} - 4.5 {}^{2} = h {}^{2} [/tex]
[tex] \hookrightarrow \:56.25 - 20.25 = h {}^{2} [/tex]
On further calculations we get :
[tex] \hookrightarrow \:h {}^{2} = 36[/tex]
[tex] \hookrightarrow \:h = \sqrt{36} [/tex]
We know that 6 × 6 is equal to 36 that means square root of 36 is 6 . So :
[tex] \hookrightarrow \pink{\boxed{\bold{h = 6 \: cm}}}[/tex]
Therefore, height of cylinder is 6 cm .Now finding volume :Substituting values in volume formula :
[tex] \longrightarrow\: \frac{1}{ \cancel{3} } \times 3.14 \times (4.5) {}^{2} \times \cancel{6}[/tex]
Step 1 : By cancelling 6 with 3 we get :
[tex] \longrightarrow \: 3.14 \times 20.25 \times 2[/tex]
Step 2 : Multiplying 20.25 with 2 :
[tex] \longrightarrow \:3.14 \times 40.50[/tex]
Step 3 : Multiplying 3.14 with 40.50 :
[tex] \longrightarrow \: \purple{\boxed{\bold{127.17 \: cm {}^{3} }}}[/tex]
Therefore, volume of cone is 127.17 cm³ .#Keep LearningA normal deck of 52 cards includes 4 suits where each suit ranges from 2 though 10 inclusive, Jack, Queen, King and Ace.

Answers
Answer: It would be A
Step-by-step explanation:
First: Find Median
18,19,|19|,20,|20,20|,21,|22|,22,26
there is 10 numbers so it would be between 20 and 20. Add 20 and 20 and you will get 40 and divide by 2 to get 20. Your median is 20 and the dot should be on top of the 20.
Second: Find Quartile 1 and 3
Since it’s 5 numbers on each side, the math is friendly. So you count the first 2, then circle the next number and count the last 2. The one you circled is your Quartile 1 and do the same for Quartile 3. Q1 should be 19 and Q3 should be 22. Check if they are underneath that number you got.
Last: now you know that you just have to find the median and the Q1 and Q3 and you should get the answer which is A.

Answers
Answer:
A
Step-by-step explanation:
I didn't learn jrf, but I believe that it is the amount of females that watch action movies divided by the total amount of females.
Amount of females who watch action movies= 99
Total females= 250
So, A seems correct.
The joint relative frequency of being male and attending a drama film, divide 124 by 229.
What is Relative Frequency?The number of times an event occurs divided by the total number of events occurring in a particular scenario is described as relative frequency.
Two things must be understood in order to compute the relative frequency:
Total number of events/trialsA category or subgroup's frequency countAction Drama Total
Male 105 124 229
Female 99 151 250
Total 204 275 479
The joint relative frequency is the frequency in a given category divided by the total number of data values.
Here, The total number of males = 229
and, the number of males that like drama = 124
To calculate the joint relative frequency of being male and attending a drama film, divide 124 by 229.
