We know that
if P is the centroid of triangle ABC
so
PD=(1/3)*BD
BD=3*PD-----> BD=3*3-----> BD=9 units
the answer is
BD=9 units
Answer:
240 pounds.
Step-by-step explanation:
Given that,
Shannon bought 518 pounds of apples.
Bill bought 278 pounds of apples.
We need to find how many more pounds of apples Shannon bought than Bill.
More Apples = Shannon Apples - Bill Apples
= 518 - 278
= 240
Hence, 240 pounds of apples Shannon bought than Bill.
Answer:
Mean 160
Standard deviation 2.63
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)
In this problem, we have that:
![\mu = 160, \sigma = 20](https://tex.z-dn.net/?f=%5Cmu%20%3D%20160%2C%20%5Csigma%20%3D%2020)
Find the mean and standard deviation of the sampling distribution of sample means with sample size n = 58.
Mean 160
Standard deviation ![s = \frac{20}{\sqrt{58}} = 2.63](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B20%7D%7B%5Csqrt%7B58%7D%7D%20%3D%202.63)
Answer:
13.8
Step-by-step explanation:
tan Q = <u>opposite </u> = <u>40</u>
adjacent x
Tan 71 = <u>40</u> x tan 71 = 40
<u> x tan 71</u> = <u> 40 </u>
tan 71 tan 71
x = <u> 40 </u> = 13.7731 = 13.8 (rounded to the nearest tenth)
tan 71
So first, you have to transform the logarithm equation to exponentials and it's
a^5 = 3
hope this helps!!
