Answer:
30-39 as where
Step-by-step explanation:
Example: find the Median of 12, 3 and 5
Put them in order:
3, 5, 12
The middle is 5, so the median is 5.
Answer:
75 minutes
50 minutes
Number of minutes to finish labelling = Total number of books labelled / Time taken to label them (speed of labelling)
Step-by-step explanation:
Complete question below:
Clare volunteers at a local library during the summer. Her work includes putting labels on 750 books.
How many minutes will she need to finish labeling all books if If she takes no breaks and labels:
a. 10 books a minute
b. 15 books a minute
Suppose Clare labels the books at a constant speed of books per minute. Write an equation that represents the relationship between her labeling speed and the number of minutes it would take her to finish labeling
Solution
a. 10 books a minute
Number of minutes to finish labelling all books at 10 books per minute = Total books / books labelled per minute
= 750 / 10
= 75 minutes
Number of minutes to finish labelling all books at 10 books per minute = 75 minutes
b. 15 books a minute
Number of minutes to finish labelling all books at 15 books per minute = Total books / books labelled per minute
= 750 / 15
= 50 minutes
Number of minutes to finish labelling all books at 15 books per minute = 50 minutes
c. The relationship between her labeling speed and the number of minutes is Total number of books labeled ÷ Time taken to label them
Number of minutes to finish labelling = Total number of books labelled / Time taken to label them (speed of labelling)
Answer:
Step-by-step explanation:
Given that a convenience store regularly buys mangoes from a wholesale dealer. For every shipment, the manager randomly inspects five mangoes from a box containing 20 mangoes for damages due to transportation. Suppose the chosen box contains exactly 2 damaged mangoes.
In the selected box 18 good mangoes and 2 damaged mangoes are there
a) Find the probability that the first mango is not damaged.
= prob of selecting 1 from any one of 18 good mangoes = 
b. Find the probability that neither of the mangoes is damaged.
=
Prob of selecting 2 from 18 good mangoes
=
c. Find the probability that both mangoes are damaged.
= Prob of selecting 2 from 2 bad mangoes
=
Answer: 6^-4
Step-by-step explanation:
6^-4•6^0
According to the law of indices, anything raised to a power of 0 is 1
So, for 6^-4•6^0
(6^0) = 1
Then, 6^-4•6^0
= 6^-4•1
= 6^-4
Since, according to law of indices anything raised to a negative power is made a denominator
= 1/(6^4)
= 1/1296
Thus, the answer is 1/1296, but in exponential form it is 6^-4
