Given that the ,mean is 8000 and the standard deviation is 1000, thus the probability that <span>tube lasts for more than 11000 hours. will be given by:
P(x>11000)
the z-score is:
z=(x-</span>μ<span>)/</span>σ
x=11000
μ=8000
σ=1000
hence:
z=(11000-8000)/1000
z=3
thus
P(x>11000)=1-P(x<11000)
But
P(x<11000)=P(z<3)=0.9987
hence
P(x>11000)=1-0.9987=0.0013
Yo sup??
you can solve this question by dividing the figure into 3 parts
first is a rectangle and the other are triangles
when u will individually take the sum of the areas u will land on option 3 ie
60 units
area of rectangle=6*4=24
and area of triangle=1/2*6*6*2 ( as there are 2 triangles )
Hope this helps
Answer:
10x + 4
Step-by-step explanation:
Combine like terms.
First combine the numbers that have the letter x:
- <u>-3x</u> <u>+ 8x</u> + 2 <u>- 3x</u> <u>+ 8x</u> + 2
- <u>-3x + 8x -3x +8x</u> + 2 + 2
- <u>10x</u> + 2 + 2
Then combine the ones that don't have the letter x
- 10x <u>+ 2</u> <u>+ 2</u>
Answer is 10x+4
