Laurie was scuba diving. Each time she dove 5 feet deeper, she would stop and clear her ears. After Laurie had checked her instruments 3 times, she was at her maximum depth of 60 feet. Which expression best represents Laurie’s maximum depth?
(4) (negative 5) (3)
(Negative 4) (Negative 5) (Negative 3)
(Negative 5) (20) (3)
(Negative 5) (Negative 20) (Negative 3)
Answers
Answer:
Laurie's maximum depth can be represented using the expressions :
(20 × 3) = 60
(3 × 4 × 5) = 60
Step-by-step explanation:
Each depth level at which ears are checked = 5 feets
Each Depth level at which instruments are checked = 20 feets
For Laurie to check her instrument ;
Number of times ears are checked = 20/5 = 4 times
This means that for Laurie to have checked her instrument 3 times :
(4 × 3 × 5) = 60 feets
Therefore, Laurie's maximum depth can be expressed as (4 × 3 × 5) = 60 feets

An experiment involves rolling two dice simultaneously. The following table shows the possible outcomes using the format of (die 1,die 2).
What is the probability of rolling 2 even numbers?
Answers
To determine the probability of rolling two even numbers, we need to find the favorable outcomes (outcomes with two even numbers) and divide it by the total number of possible outcomes.
The possible outcomes when rolling two dice are:
(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)
(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)
(3,1), (3,2), (3,3), (3,4), (3,5), (3,6)
(4,1), (4,2), (4,3), (4,4), (4,5), (4,6)
(5,1), (5,2), (5,3), (5,4), (5,5), (5,6)
(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)
Out of these, the favorable outcomes (outcomes with two even numbers) are:
(2,2), (2,4), (2,6), (4,2), (4,4), (4,6), (6,2), (6,4), (6,6)
Thus, there are 9 favorable outcomes.
The total number of possible outcomes is 36 (since each die has 6 possible outcomes).
Therefore, the probability of rolling 2 even numbers is:
\(\text{Probability} = \frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Possible Outcomes}} = \frac{9}{36} = \frac{1}{4} = 0.25\)
Hence, the probability of rolling 2 even numbers is 0.25 or 1/4.

Part A: Calculate the measures of center. Show all work. (2 points)
Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning
Answers
Answer: Please refer below mentioned explanation.
Step-by-step explanation:
Part A:
For Bay Side School: To find the median, we arrange the data in ascending order: 0, 0, 2, 3, 4, 5, 5, 5, 6, 6, 8, 8, 8 There are 13 data points, so the median is the 7th value, which is 5.
To find the mean, we sum up all the data points and divide by the number of data points: Mean = (0 + 0 + 2 + 3 + 4 + 5 + 5 + 5 + 6 + 6 + 8 + 8 + 8) / 13 = 66 / 13 ≈ 5.08
For Seaside School: To find the median, we arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 5, 5, 5, 6, 7, 7, 8, 8 There are 15 data points, so the median is the 8th value, which is 5.
To find the mean, we sum up all the data points and divide by the number of data points: Mean = (0 + 0 + 0 + 1 + 1 + 2 + 2 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8) / 15 = 57 / 15 ≈ 3.80
Part B:
For Bay Side School: Range = Maximum value - Minimum value = 8 - 0 = 8
For Seaside School: Range = Maximum value - Minimum value = 8 - 0 = 8
Part C:
Based on the measures of the center, Bay Side School has a higher mean and median compared to Seaside School. This suggests that, on average, Bay Side School tends to have larger class sizes than Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice. Additionally, both schools have the same range of 8, indicating that the spread of class sizes is similar between the two schools.

Step 2: Add -18.849556r^2 to both sides.
18.849556r2+6.283185rx+−18.849556r2=v+−18.849556r2

Answers
Answer:
1/7
Step-by-step explanation:
In the question, the possible digits are
1, 2, 3, 4, 5, 6, 7, 8, 9
Since, 0 is not allowed
The total number of possible digits are 9
The questions then says that 2 out of the 3 digits are 1 and 2, leaving the total number of possible digits to be 7
The numbers left are now;
S = {3, 4, 5, 6, 7, 8, 9}
The probability that the 3rd digit is 3 is 1 out of the seven possible values, since 3 is not repeated
Therefore,
Probability of 3 being the 3rd digit is 1/7.
the possible outcomes are 1-9 and 1 and 2 have already been used so you have to have 3-9 and it’s 1 out of those 7 numbers

A submarine submerges from the surface of the sea at the rate of 10 m/min. How long will it take to reach 300 m below the sea level
Answers
Answer:
answer is 300m/30min

Mr. Walker brought 100 cookies for two classes at school one class had 28 students, and the other had 27 students plus their two teachers. he also left 10 for the office staff and 5 for the custodians. How many cookies did he have leftover?
Answers
Answer:
Mr. Walker gave out a total of 28 + 27 + 2 = 57 cookies to the two classes and left 10 + 5 = 15 cookies for the office staff and custodians.
Therefore, the number of cookies left over is:
100 - 57 - 15 = 28 cookies
Mr. Walker had 28 cookies left over.
Step-by-step explanation:
Answer: 28 cookies
Step-by-step explanation:
We have to add up the number of cookies distributed and subtract it from the total amount of cookies he brought in order to find out how many cookies he has left over.
----------------------------------------------------------------------------------------------------------
First classFor the first class with 28 students, Mr. Walker distributed 28 cookies.
----------------------------------------------------------------------------------------------------------
Second ClassThere are 29 people in the second class, which has 27 students and 2 teachers.
Mr. Walker then gave out 29 cookies.
----------------------------------------------------------------------------------------------------------
Office Staff and CustodiansMr. Walker left 10 for the office staff, 5 for the custodians, which is a total of 10 + 5 = 15.
So, Mr. Walker distributed 15 cookies.
----------------------------------------------------------------------------------------------------------
Finding the answerWe add up the number of cookies distributed to figure out how many cookies he had leftover:
28 + 29 + 15 = 72.
This gets subtracted from the total number of cookies brought by him:
100 - 72 = 28.
----------------------------------------------------------------------------------------------------------
AnswerTherefore, after giving cookies to the two classes, the office staff, and the custodians, Mr. Walker had 28 cookies left over.
