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:
A. 1/2
Step-by-step explanation:
For 6 to become 3 and 12 to become 6, the (6,12) is being multiplied by 1/2.
Answer:
Step-by-step explanation:
2y + 1 is a binomial, in that it has two terms.
If we set 2y + 1 equal to x, then 2y = x - 1, or
x - 1
y = -----------
2
Answer:
Step-by-step explanation:
- The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , is used to find the length of any side of a right triangle.
- In a right triangle, one of the angles has a value of 90 degrees.
- The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle.
n(D) = 4
Step-by-step explanation:
Given Data:
Set D = {4, 6, 8, 10}
The number of elements in a set is called the cardinal elements (or) cardinality of the sets. This is denoted by n(A).
Here it is denoted by n(D).
The number of elements in the set D is 4.
The cardinality of the set is 4.
Hence, n(D) = 4.
