Answer:
the probability when the IQ is lower than 136 is 0.9641
Step-by-step explanation:
Given that
The mean is 100
The standard deviation is 20
We need to find out the probability when the IQ is lower than 136
So,
z value equivalent to 136 = (136 - 100) ÷ 20 = 1.8
Now
p (z < 1.8) = 0.9641
hence, the probability when the IQ is lower than 136 is 0.9641
Answer:
x=-5
Step-by-step explanation:
Set up the rational expression with the same denominator over the entire equation.
2x-2/6=3x+3/6
Since the expression on each side of the equation has the same denominator, the numerators must be equal.
2x−2=3x+3
Move all terms containing x to the left side of the equation.
−x−2=3
Move all terms not containing x to the right side of the equation.
-x=5
Multiply each term in x=−5 by −1
x=−5
Answer:
-5 is smaller than -4 bc -4 is closer to zero meaning it has more value than 5
Step-by-step explanation:
They bowled for 3 hours and spent $7.
(I have no Idea how to make a graph on this website, so I can't help you there, sorry)
Let x = number of hours
Tucker: 2x+1
Blanca: x+4
2x+1 = x+4
x=3
For the graphs your lines should have equations like this:
y= 2x+1
y=x+4
The point of intersection of these lines should be at point (3,7)
Answer:
Since both have equal length
9x - 2 = 6x + 13
9x - 6x = 13 + 2
3x = 15
x = 15/3
x = 5
Length of BC = 6(5) + 13 = 43 cm
