A random sample of 10 subjects have weights with a standard deviation of 11.0995 kg. What is the variance of their weights?
Answer:
[tex]123.19890025 kg^2[/tex]
Step-by-step explanation:
We are given that
Standard deviation, s=11.0995 kg
Sample size, n=10
We have to find the variance of their weights.
We know that
Variance=[tex](standard\;deviation)^2[/tex]
Using the formula
The variance of their weights
=[tex](11.0995)^2[/tex]
=[tex]123.19890025 kg^2[/tex]
Hence, the variance of their weights=[tex]123.19890025 kg^2[/tex]

James, Ryan and Jill share £120 in the ratio 3:2:1.
Find out how much each person recieves.
Answer:
James = £60, Ryan = £40 and Jill = £20
Step-by-step explanation:
James - 3, Ryan - 2 and Jill - 1
3 + 2 + 1 = 6
£120 / 6 = 20
Times 20 by each of the three numbers (3, 2 and 1)
3 x 20 = £60 (James)
2 x 20 = £40 (Ryan)
1 x 20 = £20 (Jill)
Answer:
James gets £60
Ryan gets £40
Jill gets £20
Step-by-step explanation:
Add up the ratio which would be 6 then divide it by the original sum which is £120 so the answer would be 20. You would then multiply 20 by each number so 20x3= 60. 20x2= 40. 20x1=20
All these should add up to your original sum and if they do you know you've done it right!
find the length of side x in simplest radical form with a rational denominator 60 30 x 2
Answer:
x = √3
Step-by-step explanation:
Looking at the given triangle,
x is the adjacent side while 2 represents the hypotenuse side.
Now, from trigonometric ratios, we know that;
Adjacent/hypotenuse = cos θ
The angle here will be 30°
Thus;
x/2 = cos 30°
We are told to find x in simplest radical form with a rational denominator.
Thus means we will use the surf value of the angle.
cos 30° in surd form = (√3)/2
Thus;
x/2 = (√3)/2
x = 2 × (√3)/2
x = (√3)/1
x = √3

Step-by-step explanation:
12 + 5/3 b + 1 1 − 18 = 20
Answer: b = 9
Step-by-step explanation:
Given
12 + 5/3b + 11 - 18 = 20
Combine like terms
(12 + 11 - 18) + 5/3b = 20
5 + 5/3b = 20
Subtract 5 on both sides
5 + 5/3b - 5 = 20 - 5
5/3b = 15
Divide 5/3 on both sides
5/3b / (5/3) = 15 / (5/3)
b = 9

Which set of angles can form a triangle?
Here are some points. What are the coordinates of G, H, and I after a rotation about the origin 90 degrees clock-wise?
Answer:
[tex]G' = (3,1)[/tex]
[tex]H' = (-4,0)[/tex]
[tex]I' = (-2,-3)[/tex]
Step-by-step explanation:
Given
See attachment for points G, H and E
Rotation: 90 degrees clock-wise
Required
Determine the coordinates after rotation
From the attachment:
[tex]G = (-1,3)[/tex]
[tex]H = (0,-4)[/tex]
[tex]I = (3,-2)[/tex]
When a point (x,y) is rotated 90 degrees clockwise, the new point is: (y,-x)
So, we have:
[tex]G = (-1,3)[/tex]
[tex]G' = (3,1)[/tex]
[tex]H = (0,-4)[/tex]
[tex]H' = (-4,0)[/tex]
[tex]I = (3,-2)[/tex]
[tex]I' = (-2,-3)[/tex]
Trevor has an investment worth $6,774.50. He made his only deposit in it 22 years ago. Given that the investment yields 2.7% simple interest annually, how big was the initial deposit?
a. $2,524.50
b. $4,024.03
c. $4,250.00
d. $11,404.88
Answer:
First, converting R percent to r a decimal
r = R/100 = 2.7%/100 = 0.027 per year.Solving our equation:
P = 6774.5 / ( 1 + (0.027 × 22)) = 4250P = $4,250.00The principal investment required to get a total amount, principal plus interest, of $6,774.50 from simple interest at a rate of 2.7% per year for 22 years is $4,250.00I do exams and quizzes if your interested!The initial deposit amount is $4,250.00.
Given that,
The worth of an investment is $6774.50The time period is 22 years. The rate of interest is 2.7%.Based on the above information, the calculation is as follows:
We know that
[tex]SI =P\times R\times T\\\\SI = P\times 2.7\% \times 22\\\\SI = 0.594P[/tex]
Now
Investment worth = P + SI
= P + 0.594P
= 1.594P
So,
1.594P = 6774.50
P = $4,250
Therefore we can conclude that the initial deposit amount is $4,250.00.
