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
Each state can set its own minimum wage. If the federal and state minimum wages are different, the highest minimum wage is used.
True
False
Answer:
True
Step-by-step explanation:
Answer:
True
Step-by-step explanation:
Wages are usually identified as the money you are paid per hour. For instance, the current minimum wage in the United States, meaning the least per hour an employer can pay a worker, is $7.25 an hour. Minimum wage is determined by the Federal Department of Labor. Individual states can set a higher minimum wage for its citizens. In those instances where the federal and state minimum wages are different, the higher minimum wage is used.

The 15th term of an arithmetic sequence is 21 and the common difference is -4.
(a) Find the first term of the sequence.
(b) Find the 29th term of the sequence.
(c) Find the sum of the first 40 terms of the sequence.
Answer:
a. Firat term of the sequence= 77
b. 29th term of the sequence= -35
c. Sum of the first 40 terms of the sequence= -40
Step-by-step explanation:
The first term of the sequence is 77, the 29th term of the sequence is -35 and the sum of the first 40 terms of the sequence is -40.
Given that, [tex]a_{15} =21[/tex] and d=-4.
What is the nth term of the arithmetic sequence?The nth term of the arithmetic sequence is [tex]a_{n} =a+(n-1)d[/tex].
To find the first term of the sequence:
[tex]a_{15}[/tex]=a+(15-1)(-4)
⇒21=a+(15-1)(-4)
⇒a=77
To find the 29th term of the sequence:
[tex]a_{29}[/tex]=77+(29-1)(-4)=-35
To find the sum of the first 40 terms of the sequence:
The first n terms of a sequence [tex]=\frac{n}{2}[2a+(n-1)d)][/tex]
[tex]S_{40} =\frac{40}{2}[2 \times77+(40-1)(-4))][/tex]
=20(154-156)=-40
Therefore, the first term of the sequence is 77, the 29th term of the sequence is -35 and the sum of the first 40 terms of the sequence is -40.

Durning the summer , a shoe store sells sneakers and sandals at a ratio of 4:7 . If the store sells 164 pair of sneakers, how many pair of sneakers and sandals does the store sell in all ?
Answer:
x = number of pairs of sandals sold = 287
Total pair of sneakers and sandals sold = 451 pairs
Step-by-step explanation:
Sneakers = 4
Sandals = 7
Sneakers : sandals = 4 : 7
If the store sells 164 pair of sneakers
Let
x = number of pairs of sandals sold
Sneakers : sandals = 164 : x
Equate both ratios to find x
4 : 7 = 164 : x
4/7 = 164/x
4 * x = 7 * 164
4x = 1,148
x = 1,148/4
x = 287
x = number of pairs of sandals sold = 287
how many pair of sneakers and sandals does the store sell in all ?
Total pair of sneakers and sandals sold = Sneakers + sandals
= 164 + 287
= 451 pairs
Total pair of sneakers and sandals sold = 451 pairs

What is the minimum number of minutes she should read each day? Write and solve an inequality. put this is an inequality pls!!
Step-by-step explanation:
x > 4 hours/week
4 hours is 240 minutes
45 minutes/ 1st book
4 hours minus 45 minutes is 3 hours and 15 minutes
3 hours and 15 minutes = 195 minutes
195 minutes ÷ 6 = 32.5 minutes
