Thepotemich [5.8K]

Answer:

About 34%

Step-by-step explanation:

Given that :

Mean, m = 59 ; Standard deviation, s = 3

Bulb replacement numbering between 59 and 62

For, x = 59

Zscore = (x - m) / s

Z = (59 - 59) / 3 = 0

For x = 62

Z = (62 - 59) / 3 = 1

P(Z < 1) - P(Z < 0)

0.84134 - 0.5

= 0.34134

Which of the following equations have no solutions?
Ivahew [28]

Answer:

A, C, D

Step-by-step explanation:

Solve all equations:

A. 33x-25=33x+25

33x-33x=25+25\\ \\0=50

This is incorrect equality, so the equation has no solutions.

B. 33x+25=33x+25

33x-33x=25-25\\ \\0=0

This is correct equality, so the equation has infinitely many solutions.

C. 33x-33=33x+25

33x-33x=33+25\\ \\0=58

This is incorrect equality, so the equation has no solutions.

D. 33x+33=33x+25

33x-33x=25-33\\ \\0=-8

This is incorrect equality, so the equation has no solutions.

kirill [66]
The formula to find the circumference of a circle is C=2*pi*r.
Substitute 9 1/4 or 9.25 for r.
C=2*pi*r
C=2*pi*9.25
C=18.5pi
The circumference of the circle would be 18.5pi.
