Answer:
a)No
Step-by-step explanation:
2x - 8x = -6x instead of 10x.
So it shoukd be -6x - 3 = 33
Answer:
The potato bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the popcorn chip bag assembly line.
Step-by-step explanation:
Popcorn mean= μ`1= 3.06
Popcorn St. Dev= σ1= 0.02
Potato Mean= μ`2= 5.05
Potato St. Dev= σ2= 0.05
Finding the z score
z= x- u / σ
Popcorn z= 3.06- 3.03/0.02= 1.5
Potato Z= 5.05-5.07/0.05= -0.4
The mean is taken to be at zero ( 0) therefore difference of 0.4 is less than a difference of 1.5
Choice 3 is the best option .
Answer:
17.96m/s
Step-by-step explanation:
Based on law of conservation of momentum;
m1u1 +m2u2 =(m1+m2)v
v is the velocities of the car after impact
Substitute the given values
1300(20)+900(15) = (1300+900)v
26000 + 13500 = 2200v
39500 = 2200v
v = 39500/2200
v = 17.96m/s
Hence the speed of the cars after impact is 17.96m/s
80 - 9.38 = 70.62
41.54(.07) = 2.91
41.54 + 2.91 = 44.45
66(.07) = 4.62
66 + 4.62 = 70.62
With an $80 gift card, Stephanie can buy a sundress as long as the ticketed price is less than or equal to $66.00.
Sphere volume = (4/3) PI * radius ^ 3
sphere volume = (4/3) PI * 5 ^ 3
sphere volume = (4/3) PI * 125
