19. 10 divided by 3 = 5 pounds
20. 5.5 divided by .5 = 11
21. no because 1.25 x 2.5 = 3.12 and she only has $3
22. the restaurant because the restaurant wants to buy 30lb and its $1.25 so 30 x 1.25 = 37.5 and the hotel buys 12 lb for $3 so that is 12 x 3= 36
Answer:
2.44746×10⁶
Step-by-step explanation:
R=(3.8×10⁵)²/5.9×10⁴
=3.8²×10¹⁰/5.9×10⁴
=1.444×10¹¹/5.9×10⁴
=1.444×10⁷/5.9
=361×10⁷/1475
=2.44746×10⁶
Answer:
See below in bold.
Step-by-step explanation:
(A) 20 -4x=12 -x+8-3x
-4x + x + 3x = 12 + 8 - 20
0 = 0 This is an Identity.
Infinite solutions.
B). 5x+4x-3=24+8x
9x - 8x = 24 + 3
x = 27. One solution.
C. 5x+6=2x+6+3x-15
5x - 2x - 3x = -15 + 6 - 6
0 = -15
No solution.
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
⇒ 
Answer:
18
Step-by-step explanation:
3 times 3 equals 9
9 times 2 equals 18
