Answer: 8
Step-by-step explanation:
Arrange the data in ascending order, and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
Rearrange 9, 9, 2, 8, 11, 6, 4 in ascending order:
2, 4, 6, 8, 9, 9, 11
The number eight appears to be in the very middle, therefore it is the median.
you can use a calculator if you want. No links please help this is very important i will give you brain thing if its correct

A chef makes small and large snacks to sell at a local art show. He cannot make more than 30
snacks before the show, with no more than 6 large snacks. The chef must make at least 10 small snacks to
earn a profit.

5. Mariel volunteers at the
animal shelter 3 times a month.
After 6 months, how many
times has she volunteered at
the animal shelter?
A sprint duathlon consists of a 5 km run, a 20 km bike ride, followed by another 5 km run. The mean finish time of all participants in a recent large duathlon was 1.67 hours with a standard deviation of 0.25 hours. Suppose a random sample of 30 participants was taken and the mean finishing time was found to be 1.59 hours with a standard deviation of 0.30 hours.
(a) Identify the parameters in this situation.
(b) Identify the statistics in this situation.
(c) Suppose we were to make a histogram of the finishing times of all participants in the duathlon. Which of the following would the histogram be a display of?
i. Population distribution
iii. Distribution of a sample
ii. Sampling distribution of means
(d) Suppose the process of taking random samples of size 30 is repeated 200 times and a histogram of 200 sample means is created. Which of the following would the histogram be a display of?
i. Population distribution
ii. Distribution of a sample
iii. Sampling distribution of means
(e) What is the standard error for the mean finish time of 30 randomly selected participants?
(f) If one participant is selected at random, what is the probability that his/her time will be less than 1.59 hours.
(g) What is the probability that another sample of 30 randomly selected participants will have a mean finishing time of 1.59 hours or less?
Answer:
A.) Parameter = 1.67 ; 0.25
B.) Statistic = 1.59, 0.30
C.) Population distribution
D.) Sampling distribution of means
E.) 0.058
F.) 0.395
G.) 0.072
Step-by-step explanation:
A.) The parameters are measured quantities or characteristics derived from the population. The parameter here describes the mean and standard deviation of all participants ;
Population mean = 1.67
Population standard deviation = 0.25
B.) Statistic are measured quantities which are characteristics of the sample. Here, we have the sample mean and standard deviation
Sample mean = 1.59
Sample standard deviation = 0.30
C.) The population distribution is the plot of the histogram prepared using data from the population (all participants)
D.) The plot of the mean value obtained from the repeated measurement or simulation of the sample data is called sampling distribution of the means.
E.) Mean finish time of 30 randomly participants :
Sample size, n = 30
Standard Error = s/√n
Standard Error = 0.30 /√30 = 0.0548
F.) If one participant is selected at random, what is the probability that his/her time will be less than 1.59 hours
P(x < 1.59)
Z = (xbar - μ) / σ ; (1.59 - 1.67) / 0.30 = - 0.267
P(Z < - 0.267) = 0.395 (Z probability calculator)
G.) P(x < 1.59)
Z = (xbar - μ) / s ; (1.59 - 1.67) / (0.30/√30) = - 1.46
P(Z < -1.46) = 0.072 (Z probability calculator)

A town has a population of 18000 and grows at 2% every year. What will be the population after 11 years, to the nearest whole number?
Answer:
~22381
Step-by-step explanation:
a=starting value = 18000
r=rate = 2%=0.02
Exponential Growth:
b=1+r=1+0.02=1.02
b=1+r=1+0.02=1.02
Write Exponential Function:
y=18000(1.02)^x
y=18000(1.02)
x
Put it all together
\text{Plug in time for x:}
Plug in time for x:
y=18000(1.02)^{11}
y=18000(1.02)
11
Evauate:
y= 22380.73755
y=22380.73755
Round:
y\approx 22381

What is a quadratic equation?A quadratic equation is a equation that is of the form -
y = f{x} = ax² + bx + c
Given is the statement as -
"12 x squared minus 14 x equals 10"
The given function can be written as -
f(x) = 12x² - 14x - 10
Refer to the graph attached. The x - intercepts show the solution of the given quadratic equation. So, we can write -
(x + 1/2)(x - 1.667) = 0
(x + 1/2) = 0 and (x - 1.667) = 0
x = -1/2 and x = 1.667

What is trigonometry?Trigonometry is the discipline of mathematics that studies correlations between angles and sides of triangles. Trigonometry is present in all of geometry because every ahead and move form may indeed be resolved to a set of triangles. Amazingly intricate connections exist between geometry and other areas of mathematics, particularly arithmetic, real or abstract, infinite series, arithmetic, and infinite series.
Here,
Sin 30 = Opposing Side/High
1/2 = 5 / y
y = 5 / (1/2)
y = 10
Cos 30 = Adjustment Side/ Hyp
√3/2 = x/y

For a given arithmetic sequence, the first term, 47, is equal to 26, and the 37 th term, a37, is equal to 278. th Find the value of the 4th term, a4.
9514 1404 393
Answer:
47
Step-by-step explanation:
Given:
a1 = 26, a37 = 278
Find:
a4
Solution:
Filling in the given values in the formula for the general term of an arithmetic sequence, we have ...
an = a1 +d(n -1)
a37 = 26 +d(37 -1) = 278
d = (278 -26)/36 = 7 . . . . . . solve for d
Then the 4th term is ...
a4 = 26 +7(4 -1)
a4 = 47
Toby buys packs of 12 racing cars for R49,99 and sells each racing car for R10 at school
1.1 Determine the cost price per racing car
1.2 calculate the profit toby makes per racing car
1.3 Determine toby's profit margin on one pack 12 racing car
Answer:
1.1 R5.83
1.2 R70.01
1.3 58.34%
Step-by-step explanation:
Given that he buys a pack of 12 racing cars for R49,99 then the unit cost for a car which is the total cost divided by the number of cars in a pack
= R49,99/12
= R4.17
If each car is sold for R10 then the profit made on each car which is the difference between the cost and the selling price
= R10 - R4.17
= R5.83
The profit margin on one pack of 12 racing cars
Profit margin is the ratio of the profit to the total selling price
The total profit (profit on one pack of 12 racing cars)
= R5.83 * 12
=R70.01
Total selling price = R10 * 12
=R120
Margin = R70.01 / R120
= 58.34%
