i am edditing my post because i got the answer wrong
Okay so this took some time but
you need 1 more cup.
in each cookie there is 1/9th of a cup so to make 45 cookies you need 1 more cup. WE COULD BE COMPLETELY WRONG
Step-by-step explanation:
Given that Rita is making a beaded bracelet. She has a collection of 160 blue beads, 80 gray beads, and 240 pink beads. We are to calculate the probability that Rita will need to pick atleast 5 beads before she picks a grey bead from her collection.
Prob for drawing atleast 5 beads before she picks a grey bead from her collection
= 1-Prob for drawing atleast one grey beed in the first 5 draws.
(Because these two are complementary events)
no of grey beeds drawn in first 5 trials is
Bi=(5,1/6)
Prob for drawing atleast one grey beed in the first 5 draws.
=1-Prob of no grey
Hence required prob=P(X=0 in first 5 draws)
= 0.4018
6th beeds onwards can be grey also.
Nearest answer is c)0.45
Answer:
Force, F = 68.93 pounds
Step-by-step explanation:
Given that,
Mass of the astronaut, m = 80.70 kg
Acceleration due to gravity on Mars, ![a=3.8\ m/s^2](https://tex.z-dn.net/?f=a%3D3.8%5C%20m%2Fs%5E2)
The force acting on him is given by using second law of motion as :
![F=m\times a](https://tex.z-dn.net/?f=F%3Dm%5Ctimes%20a)
![F=80.70\ kg\times 3.8\ m/s^2](https://tex.z-dn.net/?f=F%3D80.70%5C%20kg%5Ctimes%203.8%5C%20m%2Fs%5E2)
F = 306.66 N
Since, 1 newton = 0.224 pound
F = 306.66 N = 68.93 pounds
So, 68.93 pounds force she exerts on the martian surface. Hence, this is the required solution.
