Ron randomly pulls a pen out of a box that contains 1 red, 2 black, and 3 blue pens. He does
this 4 times, replacing the pen each time, but pulls out a blue pen only 1 time. Ron concludes
that the observed frequency of pulling a blue pen will eventually be closer to the expected
frequency based on the theoretical probability of pulling a blue pen. Which reasoning best
supports his conclusion?
Is it A, B, C, or D
PLEASE HELP ME :)
Answer: A
Step-by-step explanation:
I did this test before : )
The theoretical probability of pulling a blue pen based on the expected frequency will get closer to 1/2 as the no. of trials increases.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The first thing is to define each of the probabilities,
Theoretical probability is defined as a proportion that expresses the ways to be successful in the total events of an experiment.
Experimental probability is defined as the proportion of the proposed result for the number of experimental attempts.
Based on the above explanation, the reason that best supports is that; the more the experiment is repeated, the closer the experimental probability gets to the theoretical one, However, as the number of attempts increases, it tends to go more to what theoretically is what would happen.
The more experiments that are done, the more the theoretical attempts trend is marked
Hence, the Theoretical probability of pulling a blue pen based on the expected frequency will get closer to 1/2 as the no. of trials increases.

simplify the product (2u-4)(u^2+2u-7) pls don't just give me the answer bc i know the answer but can you pls explain how you got the answer
Answer:
2 • (u - 2) • (u2 + 2u - 7)
Step-by-step explanation:
2.1 Pull out like factors :
2u - 4 = 2 • (u - 2)
Trying to factor by splitting the middle term
2.2 Factoring u2 + 2u - 7
The first term is, u2 its coefficient is 1 .
The middle term is, +2u its coefficient is 2 .
The last term, "the constant", is -7
Step 1: Multiply the coefficient of the first term by the constant 1 • -7 = -7
Step 2: Find two factors of -7 whose sum equals the coefficient of the middle term, which is 2 .
-7 + 1 = -6
-1 + 7 = 6

There are 132 people in a kickboxing tournament. Half of the competitors are eliminated after each round. How many people are left after four rounds?
Answer:
8 people
Step-by-step explanation:
Divide half by your new product everytime you divide.
132÷2 = 66
66÷2 = 33
33÷2 = 16.5
16.5÷2 = 8.25
Round to nearest whole number and you get 8. There will be 8 people left over after 4 rounds.

Answer:
423 in²
Step-by-step explanation:
The area is given by the formula ...
A = 1/2·xy·sin(W)
A = 1/2(32 in)(96 in)sin(16°) ≈ 423.379 in²
The area of ∆WXY is about 423 square inches.
Xerxes is selling cups of lemonade. He is selling regular and pink lemonade in 3 sizes: small, medium, and large. The table displays today’s sales results:
Based upon these results, how many medium regular lemonades should Xerxes sell if he expects 640 customers tomorrow?
112 medium regular lemonades
96 medium regular lemonades
80 medium regular lemonades
128 medium regular lemonades
Find (pink lemonade).
[tex]\frac{17}{40} \frac{7}{20} \frac{7}{20} \frac{3}{10}[/tex]
Part 1
Add up the values in the table: 90+36+54+45+63+72 = 360
This means 360 total drinks were sold. Of that total, 54 were medium regular.
The percentage of medium regular is 54/360 = 0.15 = 15%
Apply this percentage to the 640 customers he plans to sell to
15% of 640 = 0.15*640 = 96
Answer: 96============================================
Part 2
It sounds like your teacher wants you to find the probability of picking pink lemonade. The table says that 36 small, 45 medium, and 72 large pink lemonades were sold. That means 36+45+72 = 153 pink lemonades were sold out of the 360 total
153/360 = 0.425
Then go through each answer choice to note that 17/40 = 0.425 as well
Therefore, 153/360 = 17/40
Answer: 17/40

A trip is going to cost $0.25
per mile in gas plus
$7 for toll charges. Write an algebraic
expression to represent the total cost of
traveling x miles plus tolls. Then use this
expression to find the total cost to go on a 300
mile trip.
Calculate your miles per gallon
Fill up your gas tank and set the trip odometer button on the instrument panel to zero, then drive normally until it’s time to stop for gas again. When you next refuel, note the trip odometer reading to get the number of miles you’ve driven. Alternatively, you can get this figure by writing down the overall odometer reading the first time you fill up and again the second time, with the difference being your miles driven. Next, divide the mileage by the number of gallons of fuel you pumped on the second gas stop to get your miles per gallon.

Jonathon kicks a kickball into the air. The height of the ball in feet can be determined using the equation h(t) = 32t - 16t^2 where t is time in seconds. To determine how long the ball is in the air, he would need to calculate what? minimum maximum y-intercept x-intercepts
Which equation is a step in finding the solution to how long the ball is in the air? h(0)=32(0)-16(0)^2
0=16t(2-t)
h(t)=-16(t-1)^2+16
h(3)=32(3)-16(3)^2
