Answer:
The median of 38, 42, 77, 47, 74, 51, 48, 41, 82, 72, 74, and 129 is 61.5.
Step-by-step explanation:
First, rearrange the data set in order.
38, 42, 77, 47, 74, 51, 48, 41, 82, 72, 74, 129
38, 41, 42, 47, 48, 51, 72, 74, 74, 77, 82, 129
Identify how many numbers are in the set. This will make it easier to infer the median.
Counting will show that this is a 12 number data set.
To find the median:
If there are an ODD amount of numbers in a data set, take the middle number. That is your median.
If there are an EVEN amount of numbers in a data set, take the middle two numbers, add them, then divide that by 2. That is your median.
Knowing this, take your middle two numbers, 51 and 72, and add them and divide by 2.
51 + 72 = 123
123/2 = 61.5
The median of this data set is 61.5.
At Giant you can get 3 cases of water for $12.99. At Shoprite you can get 4 cases of water for $12.00. Which store is the best place to shop for water?
Answer:
Shoprite
Step-by-step explanation:
At giant each case of water is 4.33 You can figure this out by dividing the overall cost of 12.99 by 3 and that gives you the cost of one case of water. At Shoprite you get 4 cases for 12.00 again you divide the overall cost of 12.00 by 4 and that gives you 3.00 so you get a better deal at shoprite there fore shoprite is the better place to shop for water
2.) which number could not be a value of y if:
y = 4x2-6
a.) 30
b.) 10
c.) -6
d.)-12
The number that could not be a value of y if y = 4x² - 6 is -12.
What is the value of y for a function of f(x)?The value of y for which a function f(x) = y = 4x² - 6 can be determined by knowing the smallest value of y for which x is equal to zero.
So, from the equation y = 4x² - 6, we will replace the value of x with zero to determine the smallest value of y.
i.e.
y = 4(0) - 6
y = 0 - 6
y = -6
Thus, any number smaller than -6 could not be a value of y for the equation y = 4x² - 6.
Therefore, we can conclude that the number that could not be a value of y if y = 4x² - 6 is -12.

$560 is divided into two parts in the ratio 3:4. What is the larger amount?
Answer:
$320
Step-by-step explanation:
1. 3x + 4x = 560 (since they are ratios, x would be the same amount)
2. 7x = 560
3. x = 80
This means that 3 and 4 should be multiplied by 80 to get the $ amount. The amounts are $240 (3*80) and $320 (4*80).
So, the larger amount if $320.
what is the difference between squaring and taking the square root ?
Answer:
Squares are the numbers, generated after multiplying a value by itself. Whereas square root of a number is value which on getting multiplied by itself gives the original value.
Step-by-step explanation:
Hence, both are vice-versa methods. For example, the square of 2 is 4 and the square root of 4 is 2.

The confidence Interval is CI = (-1.35, 1.35) and 1.74 is outside of this confidence interval and as such it is statistically significant.
How to find the confidence Interval?Formula for the confidence interval is:
CI = x' ± z(S.E)
where;
x is the mean
z is the critical value.
S.E is the standard error.
We are told that there is no difference between the population and as such; x = 0.
The confidence level is given as 95%.
z-score at 95% confidence level = 1.96.
Standard deviation of the sample mean differences is 0.69. Thus;
S.E = 0.69.
The confidence interval is:
CI = 0 ± (1.96 * 0.69)
CI = (-1.35, 1.35)
1.74 is outside of this confidence interval and as such it is statistically significant.
Complete question is;
I know that the red box has a mean value of 15.11 and the blue box's mean is 16.83. The difference of sample means is 1.74. The red standard deviation is 3.868 and the blue one is 2.933. the standard deviation of the sample mean differences is 0.69.

What is the median of this data set? 15, 14, 6, 10, 7, 15, 7, 8
The median of this set is:
9
A median is:In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value. The basic feature of the median in describing data compared to the mean is that it is not skewed by a small proportion of extremely large or small values, and therefore provides a better representation of a "typical" value. Median income, for example, may be a better way to suggest what a "typical" income is, because income distribution can be very skewed. The median is of central importance in robust statistics, as it is the most resistant statistic, having a breakdown point of 50%: so long as no more than half the data are contaminated, the median is not an arbitrarily large or small result.

The volume of the oil required to fill both containers will be 128 liters.
What is volume?
Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width, and height of cube or cubied.
Given that:-
There are two containers out of which one can hold 31/2 liters of oil while the other can hold 22/3 liters of oil. Suppose there are 4 containers of the first type and 9 containers of the second type.The volume of oil in the first container is [tex]\dfrac{31}{2}[/tex] liters so for four containers the volume will be:-
V = 4 x [tex]\dfrac{31}{2}[/tex]
V = 2 x 31 = 62 liters
The volume of oil in the second container is [tex]\dfrac{22}{3}[/tex] liters.
V = 9 x [tex]\dfrac{22}{3}[/tex]
V = 3 x 22 = 66 liters
So total volume of oil will be calculated as:-
Total volume = 66 + 62 = 128 liters
Therefore the volume of the oil required to fill both containers will be 128 liters.

What numbers between 61 and 107 that is multiple of 5, 8, and 10?
========================================================
Explanation:
We'll need to find the LCM of 5, 8 and 10.
List out the prime factorization of the three numbers.
5 = 1*58 = 2^310 = 2*5The unique prime factors are 2 and 5. The '1' isn't a prime number, so we can ignore it.
The '2' has an exponent of 3 as the largest exponent, meaning 2^3 is part of the LCM. The '5' has the largest exponent of 1. So 5^1 = 5 is also part of the LCM
LCM = 2^3*5 = 8*5 = 40
List out the multiples of 40
40, 80, 120, 160, ...
The number 80 is the only multiple between 61 and 107

The solutions to the systems of inequalities are (0.3, 1.3), (-1, -2), (0.4, 1.8) and (3.6, 0.8)
How to determine the solution to the systems?The graph of the systems of inequalities is not given.
So, I would plot a new graph to answer this question.
The systems of inequalities are given as:
y − x > 1 and 2x + y ≤ 2
x + y ≥ -3 and 5x – y ≤ -3
2x – y ≤ -1 and x + 2y < 4
4x – 3y < 12 and x + 3y ≥ 6
Next, we plot these inequalities on a graph and write out the points of intersection.
From the attached graph, we have:
y − x > 1 and 2x + y ≤ 2 ⇒ (0.3, 1.3)
x + y ≥ -3 and 5x – y ≤ -3 ⇒ (-1, -2)
2x – y ≤ -1 and x + 2y < 4 ⇒ (0.4, 1.8)
4x – 3y < 12 and x + 3y ≥ 6 ⇒ (3.6, 0.8)

a) What is the total amount of the annuity on Jennifer’s 18th birthday? [3 marks]
b) How much of the annuity is interest earned? [1 mark]
The future value of the annuity on Jennifer’s 18th birthday is $655.02
The interest earned is $55.02.
What is the future value of the annuity?An annuity is a fixed payment of money over a specified period of time.
The formula for determining the future value of the annuity is: yearly deposit x annuity factor
Annuity factor = {[(1+r)^n] - 1} / r
Where:
r = interest rate = 3.5%n = number of years = 18 - 12 = 6Future value of the annuity: $100 x [{(1.035^6) - 1} / 0.035} = $655.02
