The dot plots below show the scores for a group of students for two rounds of a quiz:
Which of the following inferences can be made using the dot plots?
A. The range of each round is the same.
B. There is no overlap between the data.
C. Round 1 scores were higher than round 2 scores.
D. Round 2 scores were lower than round 1 scores.
Answers
Answer: A. The range of each round is the same.
Step-by-step explanation:
Below shows the total score for both rounds. As you can see the totals for both rounds are very close so their range is most likely the same.
Round 1
(2 x 2) + (3 x 3) + (4 x 2) + 5 = 26
4 9 8
Round 2
(3 x 2) + (4 x 3) + (5 x 2) + 2 = 30
6 12 10

A weather forecast states that there is a 20% probability of rain on each of the next 3 days.
Complete the description of a simulation you could perform using random numbers to find the experimental probability that it will not rain on any of the next 3 days.
To simulate a 20% probability of rain over 3 days, let
of 10 numbers represent a day with rain. So,
of the numbers represent a day without rain. Then, perform multiple trials, generating
random numbers for each trial.
Answers
answer: The experimental probability that it will not rain on any pf the next 3 day is 64/125
The probability of raining is 20%
Hence, the probability that there will be no rain, is (100-20) = 80%
The probabilty that there is no rain on the first day is 80/100 = 4/5
Hence, the required probaility is (4/5)3 = 64/125

A student took 5 test in a quarter 3. His average was a 88. Four of his test scores were 87, 94, 86, and 100. What was his last test score? ( statistics) ( please write down or type it out! ) ty
Answers
Answer:
The last test score should be 73
Step-by-step explanation:
[tex]88 = \frac{( 87 + 94 + 86 + 100 + X )}{5}[/tex]
Add all the values in the parentheses together to get:
[tex]88 = \frac{367 + X}{5}[/tex]
You want to remove the 5 next, so you multiply both sides by 5.
[tex]5 * 88 = \frac{367 + x}{5} *5[/tex]
[tex]88 * 5 = 440[/tex]
You should get:
[tex]440 = 367 + x[/tex]
The last step is to subtract both sides by 367:
[tex]440 - 367 = 73[/tex]
[tex]X = 73[/tex]
I hope this helps!
Explanation: 87+94+86+100+73=440/5=88

Answer:
66°
Step-by-step explanation:
The applicable angle relations are ...
An exterior angle of a triangle is equal to the sum of the remote interior angles. Vertical angles are congruent.__
We recognize that angle HIJ, marked 105°, is an exterior angle to triangle DIJ. We also recognize that the angle marked x° is a vertical angle to angle DJI in triangle DIJ. Angles JDI, marked 39°, and DJI are remote interior angles with respect to angle HIJ.
We can use the relations described above to say that ...
∠HIJ = 39° +∠DJI
39° +x° = 105°
x° = 66° . . . . . . . subtract 39°
The measure of angle x is 66°.

Answers
The number of the blue leashes will be 240.
What are linear equations?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
It is given that:-
A pet shop owner bought 320 leashes. 30% of these leashes were pink leashes and the rest were blue and green leashes.The number of blue leashes is 3 times the number of green leashes.The number of the blue leashes will be calculated as:-
L = 320
B + P + g = 320
{ (320 x 0.3 ) } + 0.7 ( B + g ) = 320
( 96 ) + ( 2.8g ) = 320
2.8g = 320 / 96
g = 222 / 2.8 = 80
Now B = 3 x g
B = 3 x 80
B = 240
Therefore the number of the blue leashes will be 240.

Say the dilation was by 1/2, if the longest side on the original figure is 6, the longest side on the new figure should be 3. Or if the dilation was 4, if the longest side of the original figure is 3, the longest side of the new figure should be 12. After doing that, check all of the other sides with the dilation in mind and check if it adds up.

Answer: 6 more games
Step-by-step explanation:
Let’s review what we know:
The red team’s probability of winning is 70% (0.7).The blue team’s probability of winning is 65% (0.65).There are a total of 120 games.
To find the amount of games each team will statistically win, we multiply the percentage by the number of games.
Red Team: 0.7 x 120 = 84 games.
Blue Team: 0.65 x 120 = 78 games.
84 - 78 = 6 games.
Therefore, the red team will statically win 6 more games than the blue team.

Please help
Answers
Answer:
x = 35° and y = 72.5
Step-by-step explanation:
The value of x = 35° {because they are vertically opposite angles )
Now, the the value of y
=> y + y + 35° = 180° { sum of angles on a straight line is 180° }
=> 2y + 35 = 180°
=> 2y = 180 - 35
=> 2y = 145
=> y = 145/2
=> y = 72.5
y is 72.5, because it’s a line and 180-35 is 145 and then divide it by 2 which is 72.5.
