For a data consisting of 9 observations, the sum of 9 values is 360 and the sum of squares of deviation taken from the mean is 288. Find the mean and variance of the observation.
Answers
Answer:
4 ; 32
Step-by-step explanation:
Given that :
Number of observations, n = 9
Let observations = X
ΣX = 360
The mean, (m) is calculated using the formula :
m = ΣX / n
m = 360 / 9
m = 4
Σ(X - m) = 288 (sum of square of deviation )
Variance is calculated using the formula :
[Σ(X - m) / n]
Variance = Sqrt(288 / 9)
Variance = 32
If the perimeter of a square is 4x - 24, what is the
area of the square?
Answers
Answer:
A = (x - 6)² sq. units or
A = (x² - 12x + 36) sq. units
Step-by-step explanation:
P = 4s, where s is the side.
4s = 4x - 24
s = x - 6
A = s²
A = (x - 6)² sq. units or
A = (x² - 12x + 36) sq. units

£600 is invested into a savings account paying
5% compound interest per year. How much is in
the account after three years
Answers
Answer:
£694.575
Step-by-step explanation:
Using the formula for calculating the compound interest expressed as;
A = P(1+r)^t
P is the principal = £600
r is the rate = 5% = 0.05
t is the time = 3 years
Substitute into the formula;
A = 600(1+0.05)^3
A = 600(1.05)^3
A = 600(1.157625)
A = 694.575
hence the amount in the account after 3 years is £694.575

costs $5. If Jasmine needs to buy 18 cakes and has $110 to spend, how many lemon
cakes can she buy?
Set up and solve a system of linear equations to model how to determine the number
of lemon cakes Jasmine can buy for the party.
Answers
Answer:
Step-by-step explanation: Am not sure if this is the answer you guys are looking for but my in 9th grade and this is how my math teacher taught me how to do it.
one chocolate cake=?=x
one lemon cake=?=y
$270 spent
need to buy total of 18 cakes
1-chocolate cake =$7
lemon cake = $5
cakes 18=x+y
money $110=$7x+$5y
When i graphed it on the demos calculator i got (10,8).
So 10= the number of chocolate cake brought and 4= the number of lemon cake brought

1. Melissa took out a loan of $50,000 with an interest rate of 2.3% for the start-up of the Math Cafe. How much will she owe the bank if the loan term is for five years? Explain how you got your answer.
Answers
Answer:
$55,750 a
Step-by-step explanation:
Given Principal P = $50,000
Rate R = 2.3%
Time T = 5 years
Get the interest first
Simple interest = PRT/100
Simple interest = 50,000*2.3*5/100
Simple interest = 500*2.3*5
Simple interest = $5,750
Amount = Principal + Interest
Amount = $50,000 + $5,750
Amount = $55,750
Hence she will owe the bank $55,750 after 5 years
