43, 45, 2, 5, 13, 11
Median -
Q1 -
Q3 -
IQR -
Answer:
Median- 12
Q1- 5
Q3- 43
IQR- 38
Step-by-step explanation:
2, 5, 11, 13, 43, 45
Put your numbers in order of least to greatest
Since there is no given median as the amount of numbers is even, find the number in between the 2 middle numbers, in this case, the number would be 12, as it is in between 11 and 13.
To find Q1 and Q3, you need to find the first and third median, which would be 5 and 43. To find the IQR, you need to subtract Q3 from Q1, which would give you 38 in this equation

Do you think two students who made no computation errors would get different values for this numerical expression> explain (4x35)+(36x8
Answer:
Yes, they would get different values
Step-by-step explanation:
Given
[tex](4 * 35) + (36 * 8)[/tex]
Required
Would there be different value for the expression?
From the question, we understand that both students made no computational errors. This doesn't mean that the students cannot make other errors.
For instance, the expression can be solved (wrongly) in the following ways;
[tex](4 * 35) + (36 * 8) \to 4 * 35 + 36 * 8 \to 140 + 36 * 8 \to 176 * 8 = 1408[/tex]
[tex](4 * 35) + (36 * 8) \to 4 * 35 + 36 * 8 \to 4 * 71 * 8 \to = 2272[/tex]
While the correct solution is:
[tex](4 * 35) + (36 * 8) \to 140 + 288 =428[/tex]
Hence, it is possible for two students to get different values
The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1800 hours and a standard deviation of 25 hours. Using the empirical rule, what percentage of light bulbs last between 1725 hours and 1875 hours?
Answer:
99.7%
Step-by-step explanation:
The empirical rule formula states that:
68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ
Step 1
We have to find the number of standard deviations from the mean
μ = Mean = 1800 hours
σ = Standard deviation = 25 hours
For 1725 hours
μ - xσ =
1800 - 25x = 1725
25x = 1800 - 1725
25x = 75
x = 75/25
x = 3
For 1875 hours
1800 + 25x = 1875
25x = 1875 - 180
25x = 75
x = 75/25
x = 3
Step 2
From the above calculation, the bum of standard deviations from the mean is 3
Hence, the percentage of light bulbs last between 1725 hours and 1875 hours is 99.7%

Answer:
=z ^(-11) + ^(-15)
= z ^ -26
Answer:
z^-11 times z^-15 = z^-26
Step-by-step explanation:
According to exponential properties, multiplying two numbers that have exponents with the same bases should be added.
Negative exponents mean to go from a^-x to 1/a^x.
Using these properties, we evaluate the expression.
Both terms have the same base, z, so we can go ahead and add the exponents.
-11 + -15 = -26
z^-11 * z^-15 = z^-26
Because the instructions specifically say to leave it in z^n form, our answer is z^-26.

Step-by-step explanation:
After Luca took his dogs for a walk, he gave them 6 dog treats. When Luca's dad got home from work, he gave
the dogs t more treats. All together that day, Luca's dogs got 10 dog treats,
Write an equation to describe this situation.
How many dog treats did Luca's dad give the dogs?
Answer:
Step-by-step explanation:am
Luca gave them 6 treats.
His father gave them t (unknown) treats.
All together, they got 10 treats.
This would be the equation:
[tex]6+t=10[/tex]
To solve, subtract 6 from each side.
[tex]6-6+t=10-6\\t=4[/tex]
Therefore, Luca's father gave the dogs 4 treats.

Question 4 of 40
A building has three elevators. Each elevator is out of order 30% of the time.
The following set of random numbers represents 20 simulations of the
elevators, with 0, 1, and 2 representing a broken elevator and 3, 4, 5, 6, 7, 8,
and 9 representing a working elevator. In how many of the simulations were
all three elevators working?
931
188 763 841 559 144 652 277
653 673
404 396 011 843 599 797 414 761 273 844
Answer:
the answer is 9.
Step-by-step explanation:
The total stimulations in which all three elevators are working is 12(option d) by the concept of data representation.
What is data representation?Data Representation: A method for analyzing numerical data is data representation. Data representation is used to create a diagram that shows the connections between facts, ideas, information, and concepts. It is a fundamental learning technique that is clear-cut and uncomplicated. The data type in a particular domain is always what determines it. There are many various styles and sizes of graphical representations.
According to the given data:
A building has 3 elevators.
The following set of random numbers represents 20 stimulations of the elevators, with 0, 1 representing the broken elevator and 2,3,4,5,6,7,8and 9 representing a working elevator.
Stimulation data:
931 188 763 841 559 144 652 277 653 673 404 396 011 843 599 797 414 761 273 844
Now, as we observe from the given data, the stimulation in which all three elevators are working are-
763,559,652,277,653,673,396,843,599,797,273,844a total of 12 stimulations.
Thus, the total stimulations in which all three elevators are working is 12
Hence, option d is correct.

Terry rents a kayak while he is on vacation. He is required to pay a deposit of $95 plus an additional $11.50 per day. Terry only has $150 to spend on kayaking. Write and solve an inequality you can use to determine the maximum number of days Terry can afford to rent a kayak.
Answer:
A maximum of 4 days
Step-by-step explanation:
Inequality: 95 + 11.50x ≤ 150
Okay so the 95 is his fee. Then for everyday, it's 11.50 and we don't know how many days yet, so 11.50x. The 95 dollars and the 11.50x has to equal to or less than 150 since that is how much he has to spend on vaca.
95 + 11.50x ≤ 150
-95 -95
11.50x ≤ 55
/11.50 /11.50
X=4.78260869565
You would round down since he has a budget.
