Answer:
I guess it would be C, but i dont get "all numbers are answers" tho cos i thought this equation would be infinitely many solutionsssss
Step-by-step explanation:
4(x+1)+x=5(x-1)+9
4x + 4 + x = 5x -5 + 9
5x + 4 = 5x + 4
Hope this helpeddd
Answer: 0.0475
Step-by-step explanation:
Let x = random variable that represents the number of a particular type of bacteria in samples of 1 milliliter (ml) of drinking water, such that X is normally distributed.
Given: 
The probability that a given 1-ml will contain more than 100 bacteria will be:
![P(X>100)=P(\dfrac{X-\mu}{\sigma}>\dfrac{100-85}{9})\\\\=P(Z>1.67)\ \ \ \ [Z=\dfrac{X-\mu}{\sigma}]\\\\=1-P(Zz)=1-P(Z](https://tex.z-dn.net/?f=P%28X%3E100%29%3DP%28%5Cdfrac%7BX-%5Cmu%7D%7B%5Csigma%7D%3E%5Cdfrac%7B100-85%7D%7B9%7D%29%5C%5C%5C%5C%3DP%28Z%3E1.67%29%5C%20%5C%20%5C%20%5C%20%5BZ%3D%5Cdfrac%7BX-%5Cmu%7D%7B%5Csigma%7D%5D%5C%5C%5C%5C%3D1-P%28Z%3C1.67%29%5C%20%5C%20%5C%20%5BP%28Z%3Ez%29%3D1-P%28Z%3Cz%29%5D%5C%5C%5C%5C%3D1-%200.9525%3D0.0475)
∴The probability that a given 1-ml will contain more than 100 bacteria
0.0475.
Answer:
Mean = 29300
median = 23500
Modal = 23000
Step-by-step explanation:
Mean = Add them all and divide by 10
= 29300
median = average of (rank of 5th and 6th)
= (23000 + 24000) /2
= 23500
Modal = appear the most
= 23000
We will say 5 units=3 dollars
1/2 of 5 units=3 dollars (just so I don't get confused)
to find 1/3
times both sides by 2/3 to get
1/3 of 5 units=2 dollars
then times 2 both sides
1/3 of 10 units=4 dollars
so the value of 1/3 of 10 is 4
8x + 2x + 5x = 180
15x = 180
x = 180/12
x = 12
m∠1 = 8x = 8*12 = 96°
m∠2 = 2x = 2*12 = 24°
m∠3 = 5x = 5*12 = 60°
