Answer:
48 assistants
Step-by-step explanation:
If 1 executive has an average of 1.5 assistants, let x represent the number of assistants that are employed if there are 32 executives in the office.
Thus:
1.5 assistants to 1 executive = x assistants to 32 executives
1.5 : 1 = x : 32
Cross multiply
Therefore, 48 assistants were employed in the office.
Answer:
Because it helps children and other people understand how the number system works. if you develop number sense you will have a range of different maths strategies like addition subtraction
Answer:
The answer is C, 0.25.
Step-by-step explanation:
In order to find the probability of (B | A), you need to use this formula:
Conditional Probability (A has already occured)
P(B | A) = P(A and B)
-------
P(A)
If you subsitute in the values you get this:
P(B | A) = 0.10
------
0.40
0.1 divided by 0.4 is equal to 0.25.
Ratios shall be used
Selling 3x as many tie-dyed as silk is the equivalent of ratio 3:1 (Three tie dies for 1 silk)
Add up the total numbers in the ratio (By that I mean 3 + 1) to get 4
Divide the total number sold by 4 to get 42
Multiply 42 by 3 (The number of tie dyes sold in the ratio) to get 126
126 tie-dyed shirts were sold
