Step-by-step explanation:
option C is correct
as,
4x is a common magnification for scanning objectives and, when combined with the magnification power of a 10x eyepiece lens, a 4x scanning objective lens gives a total magnification of 40x.

Answer:
$4.29
Step-by-step explanation:
An easy way to do this is to move the decimal point to the left one space.
So 42.87 would become 4.287
But since we are talking about currency, we only want two numbers to the right of the decimal point: 4.28.
And since we are rounding to the nearest cent, the 7 on the end means we round up by 1, making the final answer 4.29!
Answer:
Well, I'm unsure of exactly what you're looking for but slope intercept form is y=mx+b
Step-by-step explanation:
y=mx+b
m=slope
b=y intercept (y intercept is where on the graph the line crosses with the y-axis)
This means that the y intercept is (0, -3)
Then you have the slope: Rise/Run
Run=x axis
Rise= y axis
So if you were to graph y=-1/2x-3 you would find the y intercept (0,-3)
then, because it is negative 1/2, you would move two units to the left, and one unit down (-2,-1)
Hopefully this helps you out a bit. Apologies if anything was incorrect I'm not the greatest with this. :)
Step-by-step explanation:
The probability he makes both shots is:
P = (0.90)^2
P = 0.81
There's a 81% probability he makes both shots.
Answer:
c. [1.771;4.245] feet
Step-by-step explanation:
Hello!
The variable of interest is
X: height of a student at UH
X~N(μ;σ²)
You have to estimate the population standard deviation using a 95% confidence interval.
The statistic to use for the interval is a student Chi-Square with n-1 degrees of freedom. First you have to calculate the CI for the population variance:
![[\frac{(n-1)S^2}{X^2_{n-1;1-\alpha /2}} ;\frac{(n-1)S^2}{X^2_{n-1;\alpha /2}} ]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B%28n-1%29S%5E2%7D%7BX%5E2_%7Bn-1%3B1-%5Calpha%20%2F2%7D%7D%20%3B%5Cfrac%7B%28n-1%29S%5E2%7D%7BX%5E2_%7Bn-1%3B%5Calpha%20%2F2%7D%7D%20%5D)
n=12
S= 2.5
![[\frac{11*6.25}{21.920} ;\frac{11*6.25}{3.816}} ]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B11%2A6.25%7D%7B21.920%7D%20%3B%5Cfrac%7B11%2A6.25%7D%7B3.816%7D%7D%20%5D)
[3.136; 18.016] feet²
Then you calculate the square root of both limits to get the CI for the population standard deviation:
[√3.136; √18.016]
[1.771;4.245] feet
I hope this helps!
