Answer:
Statistics is a mathematical science pertaining to the collection, analysis, interpretation or explanation, and presentation of data. It is applicable to a wide variety of academic disciplines, from the physical and social sciences to the humanities.
Statistics is maths.
Why:-
Statistics is related to maths because we study, use and even consider statistic problems with reference to mathematics.
• It is mostly used to find the census, which is maths.
• It is used to find interest rates and other banking terms using statistics, which is again related to math.
• It is also used to find the average people living in a village or panchayat, which is also math.
Therefore I strongly believe that Statistics is Maths.

A professor at a local university noted that the exam grades of her students were normally distributed with a mean of 70 and a standard deviation of 10.How many different samples of size 5 can be taken from a finite population of size 10?
252 different samples can be taken.
-------------------------
The order in which the people are chosen is not important, which means that the combinations formula is used to solve this question.
-------------------------
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
-------------------------
In this question, samples of 5 from a set of 10, so:
[tex]C_{10,5} = \frac{10!}{5!5!} = 252[/tex]
252 different samples can be taken.

C. The mean is greater than the median.
Step-by-step explanation:
. The mean is less than the median.
The statement that is most likely correct for the negatively skewed data distribution given is: B. The mean is less than the median.
What is a Negatively Skewed Data Distribution?A negatively skewed data distribution has the tail to the left of the number line, and therefore its median is usually greater than its mean.
Negative skewed: Mean < Median < Mode
No skewed: Mean = Median = Mode
Positive skewed: Mean > Median > Mode
The dot plot shows a data distribution that is negatively skewed. Therefore, the statement that is most likely to be true is: B. The mean is less than the median.

A woman wishes to rent a house within 9 miles of her work. If she lives x miles from her work, her transportation cost will be cx dollars per year, while her rent will be 4c x 1 dollars per year, where c is a constant taking various situational factors into account. How far should she live from work to minimize her combined expenses for rent and transportation
Answer:
Combined cost C(x) = cx + 4c/(x+1)
minimum C(x) ==> C '(x) = 0
==> c - 4c/(x+1)2 = 0
==> 4c/(x+1)2 = c
==> (x+1)2 = 4
==> x +1 = 2
==> x = 1 mile
Hence she should live 1 mile from work to minimise comined costs.

In a health club, research shows that on average, patrons spend an average of 46.2 minutes
on the treadmill, with a standard deviation of 4.8 minutes. It is assumed that this is a normally
distributed variable. Find the probability that randomly selected individual would spent
between 30 and 40 minutes on the treadmill.
As the problem states, the variable has a normal distribution, and thus, concepts of this distribution are used to solve this question.
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
In a health club, research shows that on average, patrons spend an average of 46.2 minutes on the treadmill, with a standard deviation of 4.8 minutes.
This means that [tex]\mu = 46.2, \sigma = 4.8[/tex]
Find the probability that randomly selected individual would spent between 30 and 40 minutes on the treadmill.
This is the p-value of Z when X = 40 subtracted by the p-value of Z when X = 30.
X = 40
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{40 - 46.2}{4.8}[/tex]
[tex]Z = -1.29[/tex]
[tex]Z = -1.29[/tex] has a p-value of 0.0985
X = 30
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{30 - 46.2}{4.8}[/tex]
[tex]Z = -3.38[/tex]
[tex]Z = -3.38[/tex] has a p-value of 0.0004.
0.0985 - 0.0004 = 0.0981
Thus, 0.0981 = 9.81% probability that randomly selected individual would spent between 30 and 40 minutes on the treadmill.

I am smaller than 7 and I have two decimal places. I am 7 when rounded to the nearest whole number. The digit in the tenths places is an even number. The digit in the hundredths places is greatest 1 -digit odd number. None of my digits are repeated. What number am I ?
Answer:
6.89
Step-by-step explanation:
Well, the number is smaller than 7 so it's 6 or less.
It's 7 when rounded up so it's got to be 6.__
The digit after 6 has to be even and has to be larger than 5 so it's either 6 or 8
The hundredths place digit is the greatest 1-digit odd number which is 9.
6.69 or 6.89 but since none of the digits can be repeated, it's 6.89

For the rhombus below, find the measures of ∠1, ∠2, ∠3, and ∠4.
Answer:
∠1 = 116 ° , ∠2 = 32° , ∠3 = 116 ° and ∠4 = 32°
Step-by-step explanation:
∠2 = 32° (The diagonals of a rhombus bisect pairs of opposite angles)
Opposite sides of a rhombus are parallel ,so
∠2 = ∠4 (Alternate interior angles )
∠4 = 32°
32° + ∠4 + ∠3 = 180° (angle sum property of a triangle)
64° + ∠3 = 180°
∠3 = 180 - 64
∠3 = 116°
∠3 =∠1 (in a rhombus opposite angles are equal )
∠1 = 116°

Mrs. Funke has #40. At the market,she buys a dozen fillets of fish at 99k per dozen ,3stacks of vegetables at #1.25 each, 27 oranges at 7k each and 4.6kg of meat at #3.20 per kilogram
Funke has #18.65 LEFT, which was obtained by Subtracting her initial amount from amount spent.
SPENDING:
Total amount = #40
fish fillet = 99k /dozen
vegetable = 3 at #1.25 each
oranges = 27 at 7k each
meat = 4.6kg at #3.20 per kg
To obtain the amount Funke has left, we subtract the total amount of items she purchased from the total amount she has :
Total cost of :
Fish fillet, 1kg = 99K = #0.99
Vegetable, 3kg = 3 * 1.25 = #3.75
Oranges, 27 = 27 * 7 = #1.89
Meat, 4.6 = 4.6 * 3.20 = #14.72
TOTAL AMOUNT SPENT = (0.99 + 3.75 + 1.89 + 14.72) = #21.35
AMOUNT SHE HAS LEFT :
(INITIAL AMOUNT - TOTAL AMOUNT SPENT)
= #40 - #21.35
= #18. 65
Therefore, the amount Funke has left after making the above purchases is #18.65
