I think what you would have to do is 12 divided by 600 that would equal 50 so im pretty sure she would have to bake and sell 50 pies to recover the cost of the oven
the steps i did were
1. i added 10 and 2 to get 12
2. i divided 12 into 600
3. then i got the answer 50
so that's how i found out the total of pies she needed to sell i hope this worked for you.
Answer: A) 35
Step-by-step explanation:
We have the following:
Now, is made up of two factors, and :
So, we have to choose a number for x containing a factor of and or . In this case, the best option is :
Hence:
Finally:
Answer:
a) 0.2182
b) 0.0691
c) 0.9309
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly b successes on n repeated trials, and B can only have two outcomes.
In which is the number of different combinations of b objects from a set of n elements, given by the following formula.
And p is the probability of B happening.
In this problem we have that:
Bin(20,0.2).
This means that
(a) P(B=4).
(b) P(B≤1).
(c) P(B>1).
Either B is less than or equal to 1, or B is larger than 1. The sum of the probabilities of these events is decimal 1. So
We have that, from b),
So
Answer:
59.5 units
Step-by-step explanation:
A rectangle is a quadrilateral (has four side) in which opposite sides are parallel and the diagonals bisect each other. The perimeter of a rectangle is:
Perimeter = 2(length + breadth) = 2(l + b)
The perimeter of rectangle WXYZ is 34 inches. Therefore:
34 = 2(l + b)
l + b = 17
Rectangle ABCD is formed by dilating rectangle WXYZ by a scale factor of 1.75. Let l' = length of ABCD and b' = breadth of ABCD hence:
Length of ABCD = l' = 1.75l
Breadth of ABCD = b' = 1.75b
Perimeter of ABCD = 2(l' + b') = 2(1.75l + 1.75b) = 2(1.75)(l + b) = 3.5(l + b)
Perimeter of ABCD = 3.5(17) = 59.5 units
