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.
How much money will there be in an account at the end of 10 years if $3000 is deposited at 3% interest compounded
semi-annually? (Assume no withdrawals are made. Use the formula A=P
-p(1-4)
for compound interest,
Answer:
$4040.57
Step-by-step explanation:
A=P(1+(r/n))^nt
P = Principal = 3000
r = rate = 0.03
n = no. times payed each year = 2
t = years = 10
A = 3000(1 + (0.03/2))^(2x10)
A = 3000(1.015)^20
A = 4040.57 (2.d.p)
Hope this helped!

Given f(x) = 3x2 + kx + 19, and the remainder when
f(x) is divided by x + 3 is 37, then what is the value of k?
Answer:
[tex]f{x} = x + 3 = 0 \\ x = - 3 \\ f( - 3) = 3( - 3) {}^{2} + k( - 3) + 19 = 37 \\ f( - 3) = 27 - 3k + 19 = 37 \\ f( - 3) = 46 - 3k = 37 \\ f( - 3) = 46 - 37 = 3k \\ f( - 3) = 9 = 3k \\ f( - 3) = k = 3[/tex]

answer this qustion plz and if get right i might give you brainlist
Answer:
A
Step-by-step explanation:
SO right off the bat it cannot be c, for they do definatly change.
Next, lets find out how much they change by.
The median would now be 120. Since adding 1 more number would make it just 120. Instead of it being 120+130/2.
This is a decrease of 5. Because we can just subtract normal number by new number: 125-120=5.
Now, the mean is already 500/4. This equals 125.
So lets add 0 to that. So now we must divide it by 1 more number, 4+1=5.
That is 500/5. This equals 100.
This is a decrease of 25. Because we can again subtrasct the normal number by the new number: 125-100=25
That is 5x more of a decrease than the mean.
SO it must be A, since the mean decreased more than the median.

Answer:
Step-by-step explanation:
Slope of line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the graph attached,
Slope of the line passing through (-3, 0) and (0, 5) = [tex]\frac{5-0}{-3-0}[/tex]
= [tex]-\frac{5}{3}[/tex]
Line passing through a point (h, k) and slope 'm' will be,
y - h = m(x - k)
Since, line passing through (11, 0) is parallel to the line given in the graph,
Slope of the parallel line will be same as [tex]-\frac{5}{3}[/tex]
Equation of a line passing through (11, 0) and slope = [tex]-\frac{5}{3}[/tex]
y - 0 = [tex]-\frac{5}{3}(x-11)[/tex]
y = [tex]-\frac{5}{3}(x-11)[/tex]
Now satisfy this equation with the points given in the options,
Option (1)
For (1.67, -15.59),
-15.59 = [tex]-\frac{5}{3}(1.67-11)[/tex]
-15.59 = -15.55
False.
Therefore, given point doesn't lie on the line.
Option (2)
For (-0.33, -13.59)
-13.59 = [tex]-\frac{5}{3}(-0.33-11)[/tex]
-13.59 = -18.88
False
Option (3)
For (0.67, -18.59),
-18.59 = [tex]-\frac{5}{3}(0.67-11)[/tex]
-18.59 = 17.22
False
Option (4)
For (1.67, -15.59)
-15.59 = [tex]-\frac{5}{3}(1.67-11)[/tex]
-15.59 = -15.55
False.
Therefore, none of the points given in the options are lying on the line.
Lindsey made a map of her town which place in Lindsey's town is located at 4,5
Answer:
the school
Step-by-step explanation:
the point given is (4,5) so let's try to hone in on that so to speak-
with that in mind, the way that i find the easiest to answer this is by using rise over run or the crawl before you walk method
seeing as how both are practically the same i'll just go with the craw before you walk method-
so we will 'crawl' to 4 along the x axis then we'll 'walk' and stop once we reach (4,5) and at (4,5) there is the school building and since her town is also located at the same point the school building is the correct answer
good luck :)

1/6 is the answer because 12 is two times bigger than 6. And the thing that is two times smaller than 2 is 1. That's the quick way of explaining it.
Answer: 1/6=2/12
Step-by-step explanation:
when you multiply something by 1 you get the numbered you multiplied it by so when you multiply [tex]1x2[/tex] you get 2 so you would
[tex]2/12[/tex]÷2=[tex]1/6[/tex]
you divide both numbers by 2 or what ever they are divisible by

Answer:
The distance between the two points is 10.3
Step-by-step explanation:
To find the length of the line joining the two points, we are going to use the distance formula
Mathematically, we have this as;
D = √(y2-y1)^2 + (x2-x1)^2
From the question;
(x1,y1) = (-3,4)
(x2,y2) = (2,-5)
Thus, we have it that;
D = √((-5-4)^2 + ((2-(-3)^2
D = √81 + 25
D = √(106)
D = 10.3

Alfredo purchased the following for breakfast:
5 bacons at $.55 each
2 eggs for $1.24
1 apple juice at $1.50 each
What was the total price in dollars and cents Alfredo paid for his breakfast?
Answer:
$6.73
Step-by-step explanation:
1 bacon = $0.55
5 x $0.55 = $2.75
1 egg = $1.24
2 x $1.24 = $2.48
1 apple juice = $1.50
$2.75
$2.48
+ $1.50
————
$6.73
Therefore, your answer is $6.73.
Answer:
In total, Alfredo paid $6.73 for his meal.
Step-by-step explanation:
To find the cost of all of the food products, multiply the quantity of the food by the prices. So, for example:
Bacon: 5 x $. 55= $2.75
Eggs: 2 x $1.24 = $2.48
Apple Juice: 1 x $1.50 = $1.50.
Now, add.
$2.75+$2.48+$1.50= $6.73
