Answer:
The right solution is:
(a) 0.8849
(b) 12.28%
(c) 4.9935
(d) 28004
Step-by-step explanation:
Given:
Mean,
= 4.5
Standard deviation,
= 0.3
(a)
P(x > 4.14)
As we know,
⇒ 
then,
⇒ 
(b)
P(4.8 < x < 5.04)
= 
= 
= 
= 
= 
or,
= 
(%)
(c)
P(x > x) = 0.05
z value will be,
= 1.645
⇒ 
(d)
P(x < 5.01)
⇒ 
P(z < 1.70) = 0.9554
⇒ 
3/4=x/16
12/16=3/4
16/16-12/16=4/16
4/16 simplified is 1/4 fl oz
57.63 or 57.6
This works because you get 55 and then you’d get 84 so you’d multiply by 7. This would be 7 and you would put a decimal and carry a 0 so it would 70. So you’d end up with 57.6
R by 6 might be the word phrase
Answer:
Step-by-step explanation:
<u>Jamie's working speed is:</u>
<u>And Bob's speed is</u>:
<u>Their working speed together is:</u>
<u>Solving for x:</u>
- 1/x = 1/30 - 1/75
- 1/x = 5/ 150 - 2/150
- 1/x = 3/150
- 1/x = 1/50
- x = 50
Bob can do the job in 50 minutes
