Answer:
Ans 1 is correct.
Step-by-step explanation:
We have given that,
p=0.85,
n=20.
we know that
1-P(x=1)=1-(0.85×0.15^19)=0.999
Ans 1 is correct.
The hypotenuse of the way that they have taken is equal to 2 miles. Jogging this distance with a rate of 5 miles per hour will take Jesse 0.4 hours. Further, for Mark to be back to the starting point, the total distance covered is 2.75. Dividing the distance by 12 miles per hour, it will take Mark only 0.23 hours. Thus, Mark will reach the initial point first.
Answer:
20.39
Step-by-step explanation:
35.99 – 15.6 = 20.39
Let us make a list of all the details we have
We are given
The cost of each solid chocolate truffle = s
The cost of each cream centre chocolate truffle = c
The cos to each chocolate truffle with nuts = n
The first type of sweet box that contains 5 each of the three types of chocolate truffle costs $41.25
That is 5s+5c+5n = 41.25 (cost of each type of truffle multiplied by their respective costs and all added together)
The second type of sweet box that contains 10 solid chocolate trufles, 5 cream centre truffles and 10 chocolate truffles with nuts cost $68.75
That is 10s+5c+10n = $68.75
The third type of sweet box that contains 24 truffles evenly divided that is 12 each of solid chocolate truffle and chocolate truffle with nuts cost $66.00
That is 12s+12n=$66.00
Hence option C is the right set of equations that will help us solve the values of each chocolate truffle.
Answer:
The percentage increase without baggage fee=25%
The percentage increase with baggage fee=41.66%
Step-by-step explanation:
Given the cost of the airline ticket two weeks ago is $300 and The present airline ticket is $375
We know that when a quantity increases from x to y then The percentage increase is equal to 
Here the percentage increase =
=25%
Now the airline charges an extra $50 baggage fee which means teh present value of the airline ticket is $375+$50=$425
the percentage increase =
=41.66%
