Answer:
The change received by Judy is $ 2.69.
Step-by-step explanation:
Bill paid = $ 10
Cost of binder = $ 1.38
Cost of pack of pencils = $ 2.05
Cost of box of erasers = $ 3.88
Total cost of the school supplies = $ 1.38 + $ 2.05 + $ 3.88 = $ 7.31
The amount of change Judy received = $ 10 - $ 7.31 = $ 2.69
Answer:
74/15
Step-by-step explanation:
x - 3 =
to remove fractions multiply each side of equation by 40
3/4x(40) - 3 = 7/10(40)
120/4x - 120 = 280/10
simplify:
30x - 120 = 28
add 120 to each side to get:
30x = 148
x = 148/30 or 74/15 simplified
I think the number would be 256 because
256 :
128*2
64*2
32*2
16*2
8*2
4*2
2*2
secondly if u divide 256 by 32 it gives 8 so it's a factor of 32
and lastly 2+5+6 = 13 which is an odd number
hope this helps!
0.28 is the same thing as 28/100.
We can divide 4 to the top and the bottom.
28 / 4 = 7
100 / 4 = 25
Therefore our answer in simplest form is 7/25.
Answer:
47.52% probability that among 10 randomly observed individuals fewer than 3 do not cover their mouth
Step-by-step explanation:
For each individual, there are only two possible outcomes. Either they cover their mouth when sneezing, or they do not. The probability of an individual covering their mouth when sneezing is independent of other individuals. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
According to a study done by Otago University, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267.
This means that
What is the probability that among 10 randomly observed individuals fewer than 3 do not cover their mouth
10 individuals, so n = 10.
In which
47.52% probability that among 10 randomly observed individuals fewer than 3 do not cover their mouth
