The table shows the results of 500 experiments. Each experiment involved one person choosing one card from each of two identic decks of cards, labeled 1 through 5. What is the experimental probability of a person choosing a 2, then a 3? Express the answer as percent. ( I really need help with this, I tried looking at my notes and my brain literally can’t function )
Answers
Unfortunately, I cannot see the table you mentioned. However, I can explain how to calculate experimental probability and apply it to the given situation.
Experimental probability is the ratio of the number of times an event occurs to the total number of trials or experiments conducted. In this case, the event is a person choosing a 2, then a 3 from two identical decks of cards labeled 1 through 5.
Let's say we conducted 500 experiments, and in 50 of those experiments, a person chose a 2, then a 3. Then the experimental probability of choosing a 2, then a 3 is:
Experimental probability = (Number of times the event occurred) / (Total number of experiments) = 50 / 500 = 0.1
To express this as a percent, we simply multiply by 100:
Experimental probability as percent = 0.1 x 100% = 10%
Therefore, the experimental probability of a person choosing a 2, then a 3 from two identical decks of cards labeled 1 through 5, based on 500 experiments, is 10%.

282 cubic inches
Step-by-step explanation:
Let's have A be the top figure, B the middle, and C the bottom.
First, we need the volume for A, B, and C. And after, add them up.
Figure A : 1 · 5 · 2 = 10 cubic inches
Figure B : 3 · 3 · 8 = 72 cubic inches
Figure C : 10 · 4 · 5 = 200 cubic inches
Now we add A+B+C, so the equation is:
10+72+200=282 cubic inches
Hence, the volume of the this figure is 282 cubic inches.

Odessa and Randall play a game in which the highest score wins. They record their scores and plot them on the dot plots, as shown.
Based on the data, which statement about Odessa's and Randall's scores is true?
A. Odessa is generally worse at the game than Randall because her median score is lower than Randall's median score.
B. Odessa is less consistent at the game than Randall because the variability of her scores is greater than the variability of Randall's scores.
C. Randall is generally better at the game than Odessa because his median score is higher than Odessa's median score.
D. Randall is more consistent at the game than Odessa because the variability of his scores is greater than the variability of Odessa's scores.
(I got confused on the answers because of some of the repeating words)
Answers
Answer: B. Odessa is less consistent at the game than Randall because the variability of her scores is greater than the variability of Randall's scores.
Step-by-step explanation: I summed up all of Randall's scores and got 410 and then I summed up all of Odessa's scores and got 660 so that means that Odessa's scores are bigger than Randall's scores.
The data on the dot plot shows that the B. Odessa is less consistent at the game than Randall because the variability of her scores is greater than the variability of Randall's scores.
What do the dot plots show ?Odessa's scores are more spread out and less consistent than Randall's scores. This could be due to a number of reasons, such as differences in skill level, luck, or consistency in performance.
Overall, a greater degree of variability in Odessa's scores compared to Randall's scores suggests that Odessa's performance in the game is less predictable and consistent than Randall's performance.

Nathan is using the random number string below in a simulation. He wants to determine how many people he has to meet before he finds one that is left-handed.
1 5 8 9 7 8 2 3 6 7 0 5 6 5 9 3 7 0 9 4
He lets each number in the string represent a person, with 0 representing left-handed people and 1 through 9 representing right-handed people. According to the simulation, how many people does he have to meet until he finds the first left-handed person?
Answers
Answer:11people
Step-by-step explanation:
For this question, ignore all numbers that are not 0 to start with, as 0 is the only number that shows you an individual who is left-handed. Now, take a look at where 0 is. How many numbers do you see before it? There are 10 numbers before 0, and if you add 1 more, there are 11 in total. The first left-handed person is the 11th person Nathan will meet.

Explanation:
For (A), first multiply 77 by 2 then subtract from 330
77x2=154
330-154=176
For (A), second divide 176 by 2
176/2=88
Length=88
For (B), divide 6734 by 91
6734/91=74
Hope this helps!
Answer:
(a) 88 m
(b) 74 cm
Step-by-step explanation:
You want the length of a garden with a perimeter of 330 m and a width of 77 m, and you want the width of a window with an area of 6734 cm² and a length of 91 cm.
(a) PerimeterThe perimeter of a rectangle is given by the formula ...
P = 2(L +W)
Filling in the given values, we can find the unknown.
330 = 2(L +77)
165 = L +77 . . . . . . . divide by 2
165 -77 = 88 = L
The length of the garden is 88 meters.
(b) AreaThe area of a rectangle is given by the formula ...
A = LW
Filling in the given values, we can find the unknown.
6734 = 91W
6734/91 = 74 = W
The width of the window is 74 cm.

how to check:-17=-3x-2
Answers
Answer: x=5
Step-by-step explanation:
To solve this equation, we have to get the x alone. To cancel out the -2 on the right side, you will add 2 to both sides of the equation since -2 and 2 cancels out. Now you have -15=-3x. Now you will divide by -3 on both sides since the -3 in the equation is being multiplied by x. -15 divided by -3 equals 5. Therefore x=5.
x=5

To add these fractions, we need to find a common denominator. The least common multiple of 7, 4, and 3 is 84, so we will use 84 as the common denominator.
2/7 + (-3/4) + (-2/7) + 4/3
= (2/7) * (12/12) + (-3/4) * (21/21) + (-2/7) * (12/12) + (4/3) * (28/28) (multiplying each fraction by an equivalent form to get a common denominator of 84)
= 24/84 - 63/84 - 24/84 + 112/84 (simplifying each fraction)
= -51/84 + 112/84 (combining like terms)
= 61/84 (simplifying the resulting fraction)
Therefore, 2/7 + (-3/4) + (-2/7) + 4/3 = 61/84.
Answer:
7/12
Step-by-step explanation:
2/7 + (-3/4) + (-2/7) + 4/3
2/7 - 3/4 - 2/7 + 4/3 (+ * - = -)
2/7 - 2/7 - 3/4 + 4/3 (Distribution Property)
0 - 3/4 + 4/3
- 3/4 + 4/3
4/3 - 3/4 (Distribution Property)
LCM = 3 * 4

(16 - 9) / 12
7/12
So, the final answer is 7/12.

Elena has a budget of $50 for a new watch. she finds two watches that are $8 above and $8 below her budget, respectively.
Part A
write an absolute value equation that can be used to find the prices of the wayches elena finds
0=|x+___|+___
Part B
What are the prices of the watchee Elena finds?
$______and$______
Answers
The first watch is 58 and the other watch is 42
The requreid, The absolute value equation to represent this situation is 0 = |x - 50| + 8 and Elena finds a watch that costs $50. The other two watches are priced at $42 and $58.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Part A:
Let x be the price of the first watch she finds. Then the price of the second watch is x - 16 (since it is $8 below her budget).
The absolute value equation to represent this situation is:
0 = |x - 50| + 8
Part B:
To solve the absolute value equation, we need to consider two cases:
Case 1: x - 50 is positive
If x - 50 is positive, then we can write the equation as:
0 = x - 50
x = 50
This means that the watch Elena finds costs $50, which is exactly her budget.
Case 2: x - 50 is negative
If x - 50 is negative, then we can write the equation as:
0 = -(x - 50)
0 = -x + 50
x = 50
Again, this means that the watch Elena finds costs $50.
So, Elena finds a watch that costs $50. The other two watches are priced at $42 and $58.
