He edge length would be 24
Step-by-step explanation:
Here we are going to use the Pythagoras theorem to get the Hight of the Television
X Being the unknown side
So the height is 27.2in
The Are of the screen would be L x B
27.2 x 32 = 870.2 in^2
We will use Pythagoras for the last question also
She will need 51.23 in screen size
Answer:
σ m = 4.56 (approx.)
Step-by-step explanation:
Standard deviation of the sampling distribution of the sample mean [σ m] : is a measure of Sample dispersion. It is also called standard error. It falls with increase in sample size
Standard Deviation of sample mean [σ m] = σ / √ n
Given : Standard Deviation = σ = 20
Number of sample units : n = 19
[σ m] = 20 / √ 19
= 20 / 4.36
= 4.56
Answer:
C
Step-by-step explanation:
The data is skewed, and the lowest number of crackers in a package was 7
Answer:
A = $2,122.20
Step-by-step explanation:
A = P(1 + r/k)^kt
Where,
A = future amount
P = principal = $1,500
r = interest rate = 7%
k = number of periods compounded = 4
t = years = 5 years
A = P(1 + r/k)^kt
= 1,500 (1 + 0.07/4)^4*5
= 1,500 (1 + 0.0175)^20
= 1,500 (1.0175)^20
= 1,500 (1.4148)
= 2,122.20
A = $2,122.20
