Mr. Clark claims that he has a coin that is weighted so that the probability of heads is 40%. To test this, his students flip the coin 200 times and calculate the relative frequency of heads and tails.
(OPTIONS FOR CHOOSE (IN ORDER))
(Q1) Reasonably Close To/Very Different From
(Q2) True/False
(Q3) 0.50/0.60/0.70
Answers
Answer:
1. The relative frequency of heads is (A) reasonably close to 40%.
2. Mr. Clark's claim about the theoretical probability is likely to be (A) True.
3. This means that the theoretical probability of tails is most likely 0.6 for this coin.
( I also had this question before)
Answer: I think the answers are
(Q1) is A (Q2) is A and (Q3) is B
Step-by-step explanation: A for the first question because the Law of probability says: If you run a shorter trial then you get biased results but run a more extended trial you get unbiased results and his results would have to be true also the relative frequency is 0.6

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.

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

Explain how to prove that an image is the dilation of a preimage in the coordinate plane.
Answers
Answer:
Look at the longest side of the original figure and then look at the longest side of the new figure.
Step-by-step explanation:
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.
I'll give 100 points Devon and his friends bought strawberry wafers for $3 per packet and chocolate wafers for $1 per packet at a carnival. They spent a total of $30 to buy a total of 22 packets of wafers of the two varieties.
Part A: Write a system of equations that can be solved to find the number of packets of strawberry wafers and the number of packets of chocolate wafers that Devon and his friends bought at the carnival. Define the variables used in the equations.
Part B: How many packets of chocolate wafers and strawberry wafers did they buy? Explain how you got the answer and why you selected a particular method to get the answer.
Answers
[Part A]
A system of equations is different equations that can be used to find different variables. We will write one for the money spent and one for the items bought. Let x be strawberry wafers and y be chocolate wafers.
$3x + $1y = $30
x + y = 22
[Part B]
We will graph the two systems to solve. I am choosing this method because it is the quickest and easiest.
The point of intersection is the solution. Remember x is strawberry and y is chocolate. They bought 4 strawberry and 18 chocolate.

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.

Answers
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°.

5. s ÷ 10, 8b, h + 7, 3r - 8
6. 248
Step-by-step explanation:
5.s divided by 10 would be written as s ÷ 10. 8 times b would be written 8b or 8 x b. 7 more than h would be written h + 7 because you are doing 7 more that h not h more than 7. 8 less than the product of 3 and r is written 3r -8 because the word product means to multiply. So, the question is 8 less than 3 times r which is written 3r -8 or (3 x r) - 8.
6. is 248 because if you drive 62 miles each hour and you drive for four hours you will go 248 miles in total. You just multiply 62 times 4.
