Emi computes the mean and variance for the population data set 87, 46, 90, 78, and 89. She finds the mean is 78. Her steps for finding the variance are shown below.
What is the first error she made in computing the variance?
A.) Emi failed to find the difference of 89 - 78 correctly.
B.) Emi divided by N - 1 instead of N.
C.) Emi evaluated (46 - 78)2 as -(32)2.
D.) Emi forgot to take the square root of -135.6.
Answer: Choice C) Emi evaluated (46-78)^2 as -(32)^2
Explanation:
The "46-78" is inside the parenthesis, so the result must also stay in the parenthesis. This means (46-78)^2 would become (-32)^2. The negative must be inside the parenthesis as well. Squaring the "-32" leads to a positive result, so every item being added is positive after the squaring operations are applied.

Step-by-step explanation:
first, group the terms with the same power together and it would become (-9n⁵-4n⁵)+(n³-9n³)+(11n+6n). then, combine the terms in each group together which would get -13n⁵-8n³+17n as the answer
An onion soup recipe calls for 3 2/3 cups of chopped onions. Katrina has already chopped 1 1/3 cups of onions. She wants to know how many more cups she needs to chop. Katrina still needs to chop cups of onion soup recipe calls for 3 2/3 cups of chopped onions. Katrina has already chopped 1 1/3 cups of onions. She wants to know how many more cups she needs to chop. Katrina still needs to chop cups of onions
Answer:
[tex]2\dfrac{1}{3}\ \text{cups}[/tex]
Step-by-step explanation:
Amount of chopped onions required = [tex]3\dfrac{2}{3}\ \text{cups}[/tex]
Amount of onions Katrina has already chopped = [tex]1\dfrac{1}{3}\ \text{cups}[/tex]
Amount of onions that are required to be chopped is given by
[tex]3\dfrac{2}{3}-1\dfrac{1}{3}\\ =\dfrac{11}{3}-\dfrac{4}{3}\\ =\dfrac{7}{3}\\ =2\dfrac{1}{3}\ \text{cups}[/tex]
Hence, the amount of onions that are required to be chopped is [tex]2\dfrac{1}{3}\ \text{cups}[/tex].

Step-by-step explanation:
A number, x, rounded to 1 decimal place is 3.7
Write down the error interval for x.
Answer:
The error in rounding a number is half of the unit of measure. The number was rounded to the nearest 0.1 unit so the error is half of 0.1 which is 12⋅0.1=0.05
2
1
⋅0.1=0.05. Since 3.7+0.05=3.753.7+0.05=3.75 and 3.7−0.05=3.653.7−0.05=3.65, then the error interval is \boxed{3.65\le x<3.75}.

Martin says that f(x)=2(4)^x starts at 4 and has a constant ratio of 2. What error did Martin make? Explain.
Answer:
A general exponential equation is written as:
f(x) = A*(r)^x
Where:
A is the initial value, this is the value that the function takes when x = 0.
r is the rate of growth
x is the variable.
In this case, the function is:
f(x) = 2*(4)^x
The initial value is:
f(0) = 2*(4)^0 = 2*1 = 2
The initial value is 2.
And the rate of growth is 4.
So Martin seems to mixed these two values (he said initial value = 4, and rate = 2, which is the opposite of what we found)
If 10 apples cost $8.95, how much will 4 apples cost?
Step-by-step explanation:
here's your solution
=> cost of 10 apple = $ 8.95
=> cost of 1 apple = $8.95/10 = $ 0.895
=> cost of 4 apple = $ 0.895*4
=> cost = $3.580

Mr Malloy wants to make sure amo and max get the best possible grade after five tests and can either give a grade based on the median or the mean
Answer:
• Median for Amo
• Mean for Max
Step-by-step explanation:
Amo's mean score:
= (97 + 92 + 89 + 55 + 90)/ 5
= 84.60
= 85
Max's mean score:
= (68 + 97 + 65 + 92 + 65) / 5
= 77
Amo's median:
First arrange the numbers in ascending order:
55, 89, 90, 92, 97
Median is middle which is 90.
Max's median:
65, 65, 68, 92, 97
Median is 68
Mr Javier should use Median for Amo and Mean for Max.
James has $10 in 5-cent and 10-cent coins in his change jar and counts 157 coins in total. How many 10-cent coins does he have?
Show working out!!
Answer:
10 cent coins = 43
Step-by-step explanation:
x = 10 cent coins
y = 5 cent coins
x + y = 157, then y = 157 - x
$10 = 1000 cents
0.10x + 0.05y =1000
substitute for y:
0.10x + 0.05(157 - x) = 1000
0.10x + 7.85 - 0.05x = 1000
combine like terms:
0.05x = 2.15
x = 43
y = 114

Find the length and width of a similar rectangular screen if the length is 5 meters more than 6 times its width, and the viewable area is 5,550 square meters.
Answer:185 m , 60 m
Step-by-step explanation:
Given
Length is 5 m more than 6 times its width
Suppose width is [tex]x[/tex]
So, length is given by [tex]6x+5[/tex]
The area is given by [tex]l\times b[/tex]
Put values of length and width
[tex]\Rightarrow (6x+5)x=5550\\\Rightarrow 6x^2+5x-5550=0\\[/tex]
On solving the quadratic equation, we get [tex]x=30[/tex]
Length is [tex]6\times 30+5=185\ m[/tex]
Width is [tex]x=30\ m[/tex]
