Answer:
3.621492248 x 10 to the power of 93
Step-by-step explanation:
That was what my calculator got.
A = 11
Step-by-step explanation:
For the problem on the LHS, the 2nd line should have been written as
5(A + 1) = 3(2A - 2)
Now let's solve for A:
5A + 5 = 6A - 6
-6A - 5. -6A. - 5
______________
-A = - 11
or A = 11
This is the correct solution and it will now work out right.
13 goes into 28 evenly two times - 13 x 2 = 26
What's left is 28 - 26 = 2
The remainder of 28 / 13 is 2.
Hope this helps!! :)
Subtract 24 to 78. Divide the answer by 24. Multiply it by 100. So the final answer is 225%.
We have a starting value of 24. In order to reach 78, we need to multiply a number to 24 and add it to 24.
Making the equation 24 + 24P = 78.
Transpose 24 to the other side, you’ll get 24P = 78--24.
24P=54.
Divide both sides by 24, you’ll get P = 2.25
Multiply 2.25 by 100 to get the percentage.
So, you’ll get the final answer 225%
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
