You have to use your standard normal table (or calculator) for these. The area under the curve should be 1, a z-value corresponds to the probability and is area to the left of that z.
a. A simple reverse lookup of 0.9750. z=1.96
b. Total area up to z would be 0.5+0.4750, so reverse look up 0.9750 and find z=1.96
c. A simple reverse lookup. z=0.61
d. Area to the left of z would b 1-0.1314, so lookup 0.8686 and find z=1.12
e. A simple reverse lookup. z=0.44
f. Just invert the area: 1-0.33 = 0.67 and reverse lookup: z=0.44
Answer:
(5,38)
Step-by-step explanation:
<u><em>The correct question is</em></u>
A system of equations is shown below:
y = 8x − 2
y = 9x − 7
What is the solution to the system of equations?
(−5, 38)
(−5, −38)
(5, 38)
(5, −38)
we have
----> equation A
----> equation B
Solve the system by substitution
substitute equation B in equation A
solve for x
<em>Find the value of y</em>
Substitute the value of x in the equation A or in the equation B
therefore
The solution is the point (5,38)
24 students ===> 100% of the third test &
150% of the second test is 150% of 24 students:
So the 150% in the second test correspond to 150% x 24 = 36
Hello, there!
<span>This is already simplified as there are no like terms that can be combined. x^3 is different than x^2, so it can't be combined.
x^3 is different from y^2 so it can't be combined.
And finally, x^2 is different from y^2, so it can't be combined either.
