Dina has a number cube that she uses for a game.
The number cube has the shape of a triangular pyramid, with 4 faces numbered 1 through 4. Dina rolls the number cube 100 times and records the results. She calculates the relative frequency of each outcome.
Outcome 1 2 3 4
Relative Frequency 0.23 0.24 0.26 0.27
Which statements about Dina's experiment are true?
Select each correct answer.
The relative frequencies in the table are reasonably close.
The theoretical probability of rolling an even number is 0.51.
The relative frequency of rolling an even number is 0.51.
The number cube is not likely to be fair.
Answer: the relative frequencies in the table are reasonably close.
Step-by-step explanation:
Theoretically relative frequency for all numbers are 0.25. If cube is cast
100 times there my be small fluctuations.

A restaurant placed a 2- quarter pitcher of water on each 76 tables. the water was severed from from a 50- gallon containter. How many QUARTS of water remained in the 50- gallon container after all ther pitchers were filled
(4 quarts=1 gallon)
Answer:
There would be 12 gallons left
Step-by-step explanation:
If there was 76 of the 2 quarter pitchers that would make 152 Qt and 152 Qt equals 38 gallons so 50 - 38 = 12

Caleb throws a ball three times for his dog Leo. For each throw, Leo either
catches the ball or misses it. Identify the sample space (the correct list of
possible outcomes) for the results.
C = catch, M = miss
The notation CMC means Leo caught the first ball, missed the second one,
and caught the third one.
A. {CCCC, CCMM, MMMM}
B. {CCC, CCM, CMC, MCC, MMC, MCM, CMM, MMM}
C. {CCC, CMC, MMM}
D. {CC, CM, MC, MM}
Answer:
B {CCC, CCM, CMC, MCC, MMC, MCM, CMM, MMM}
Step-by-step explanation:
Ima try to explain this in the process of elimination:
A isn't right since he only throws the ball 3 times
C isn't right, since he could catch it, miss, then catch again and would still match the criteria stated.
D Isn't right since he threw it 3 times, not twice
that only leaved B to be correct! Hope this helps!

Another person pays $90.87 each month toward the purchase of a saxophone. After 5 months, the person has paid 65% of the total cost of the saxophone.What is the total cost,in dollars,of the saxophone?Show your work or explain your answer.
Answer:
$699
Step-by-step explanation:
90.87 * 5 = 454.35
454.35 = 65%
/65 /65
6.99 = 1%
*100 *100
$699 = 100%
Total Cost = $699
Jonathan went to the movies with $48 he earned at his after-school job. The ticket cost $8.75. He spent $7.45 for refreshments. How much money did he have left?

A math class is having a discussion on how to determine if the expressions 4 x minus x + 5 and 8 minus 3 x minus 3 are equivalent using substitution. The class has suggested four different methods.
Which describes the correct method?
*Both expressions should be evaluated with one value. If the final values of the expressions are both positive, then the two expressions must be equivalent.
*Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.
*Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are positive, then the two expressions must be equivalent.
*Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.
Answer:
Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.

Which key correctly represents the information below?
A) 11 | 2 = 12
B) 1 | 2 = 12
C) 11 | 2 = 112
D) 11 | 2 = 13
Answer:
The correct answer is C) 11 | 2 = 112
Step-by-step explanation:
That is because that is how these kinds of stem and leaf plots work. You add the number on the left to each individual number of the right. For example, the numbers in row 11 are actually:
112, 112, 115, 118.
The reason why we have stem plots is that it removes the need to write the 11 at the beginning of the number and lets you interpret and analyze the data more easily.
Stemplots are also pretty annoying and useless, and something you'll basically never use, so don't worry if they don't make much sense :)

a bag of jellybeans has 20 watermelons jellybeans, 45 sour apple jellybeans, 30 orange jellybeans and 5 cotton candy jellybeans. if you reach in and grab one jellybean, what is the probability that it will be watermelon flavored
help fast pls 7th grade
The probability that it will be watermelon flavored is -
P{E} = 1/5.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is a bag of jellybeans has 20 watermelons jellybeans, 45 sour apple jellybeans, 30 orange jellybeans and 5 cotton candy jellybeans.
We can write the probability as -
P{E} = (20)/(20 + 45 + 30 + 5)
P{E} = 20/100
P{E} = 1/5
Therefore, the probability that it will be watermelon flavored is -
P{E} = 1/5.

Answer:
y+1 = -1/3(x+3)
Step-by-step explanation:
we can use this formula to answer this question
y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the point and m indicates the slope
y-(-1) = -1/3(x-(-3)
y+1 = -1/3x-1
y = -1/3x -2
You and your friends went to UNO's for dinner (way back in 2019). Together the total bill for your meals was $40. You have a 15%-off coupon for the meal! Then, after the discount, a 7% sales tax is applied. What is the final price, after the discount and the tax, that you are your friends have to pay for the meal?
Answer:
$36.38
Step by step explanation:
First, we need to find out what 1% of $40 dollars is. To do this, we divide 40 by 100.
This gives us $0.40.
To then find out fifteen percent of $40, you then times $0.40 by 15.
This gives us 6 dollars.
Now, to work out the discount, we take 6 from 40.
$40 - $6 = $34
Now we have to work out the tax.
Again, we have to work out what 1% of $34 is.
This gives us $0.34
Then times that by 7 to find 7%
0.34 x 7 = $2.38
Since this is tax we have to add instead of subtracting.
$34 + $2.38 = $36.38 as the final bill.
