Answer:
option C.
Step-by-step explanation:
According to equidistant chords theorem, two chords of a circle are congruent if and only if they are equidistant from the center of the circle.
Congruent means they are equal in length.
Using equidistant chords theorem, we can fill the blank.
In a circle, two chords that are equidistant from the center of the circle are always equal in length.
Therefore, the correct option is C.
10,500 + 1.15*10,500 = 22,575 . . . . . dollars
Answer:
Step-by-step explanation:
The lengths of human pregnancies are normally distributed with a mean of 268 day and a standard deviation of 15 days
From the information given,
mean, u =268
standard deviation, s = 15
x is number of days
For normal distribution,
z = (x-u)/s
Probability of x greater than or equal to 300 will be 1 - probability of x lesser than 300
z = (300-268)/15 =32/15 = 2.13
Looking at the normal distribution table, the value is 0.98341
Probability of x greater than or equal to 300 will be 1 -0.98341
= 0.01659
