75p is the correct answer because 1 lemon is 15p
Answer:
A = 38°
B = 50.32°
C = 91.68°
a = 8
b = 10
c = 12.77
Step-by-step explanation:
The first thing is to find the angle B, like this:
sin B = b * sin A / a = 10 * sin (38 °) / 8
sin B = 0.77
B = arc sin (0.77)
B = 50.32 °
For angle C, it would be:
C = 180 - 38 - 50.32
C = 91.68 °
Side c, we calculate it like this:
c = a * sin C / sin A = 8 * sin (91.68 °) / sin (38 °)
c = 12.77
Answer:
1/2
Step-by-step explanation:
isolate the variable by dividing each side by factors that don't contain the variable
Answer:
20.27
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation ![s = \frac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?
This is s when
. So
![s = \frac{136}{\sqrt{45}} = 20.27](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B136%7D%7B%5Csqrt%7B45%7D%7D%20%3D%2020.27)
So the correct answer is:
20.27
