Answer:
$3934
Step-by-step explanation:
We know that the currency of different countries are different.
So, one US dollar = 1.23 Canadian dollar
Given : $3192
A trinidadian changed some US dollar to Canadian dollar who plans to visit Canada.
He exchanged $3192.
Therefore,
1 US dollar = 1.23 Canadian dollar
The value of $ 3192 will be equal to = 1.23 x 3192
= $ 3933.96
≈ $ 3934
Therefore, triodion received = $ 3934.
Answer:
Step-by-step explanation:
Hello!
You need to construct a 95% CI for the population variance of the forces the safety helmets transmit to wearers.
The variable of interest is X: Force a helmet transmits its wearer when an external force is applied (pounds)
Assuming this variable has a normal distribution, the manufacturer expects it to have a mean of μ= 800 pounds and a standard deviation of σ= 40 pounds
A test sample of n=40 was taken and the resulting mean and variance are:
X[bar]= 825 pounds
S²= 2350 pounds²
To estimate the population variance per confidence interval you have to use the following statistic:
And the CI is calculated as:
[;]
[;]
[1577.45; 3867.09] pounds²
Using a confidence level of 95% you'd expect that the interval [1577.45; 3867.09] pounds² contains the value of the population variance of the force the safety helmets transmit to their wearers when an external force is applied.
I hope this helps!
Answer:
a is the variable, 3 is the coefficient, the degree is 2

Answer:
277.3 unit^3
Step-by-step explanation:
volume of triangular pyramid = 1/3 * A*H
H= 16
A is the area of base triangle
A= 1/2 * bh
b = 13
h = 8
A = 52 unit^2
volume = 1/3 * 52 * 16 = 277.3
