Basically we have to calculate P X < 0.95. By using the normal distribution formula for any random variable we can get our answer.
SO first from z table we will have to check the corresponding z value from the table. After we get that value we can do X - mean / the std dev = that particular value that i am naming A.
SO X - 5 / 0.5 = A. Now we can solve X for our answer.
Don't mark me right on this but I think it is 4:1 but I may be wrong.
Answer:
middle term = 7x
Step-by-step explanation:
in order to find the middle term, we will expand the bracket on the left hand side and compare the expressions on both sides.
(x + 2) (3x + 1) = 3x² + ___ + 2
let the unknown expression = y
(x + 2) (3x + 1) = 3x² + y + 2
Expanding the bracket on the left hand side by multiplication:
x + 2( 3x + 1) = (x × 3x) + (x × 1) + (2 × 3x) + ( 2 × 1)
= 3x² + x + 6x + 2
= 3x² + 7x + 2
Comparing with the expression on the right hand side:
3x² + 7x + 2 = 3x² + y + 2
∴ y = 7x
middle term = 7x
Answer:
10 cups
Step-by-step explanation:
Ratio of water:juice = 2:3
2:3
?:15
3*5 = 15
2*5 = 10
It's an equilateral triangle, therefore
AB = BC = BA
We have the equation:
<h3>Answer: BC = 3</h3>
