Answer:
I'm rusty on this but I believe:
the median is 54
the lower quartile = 16
the upper quartile is 72
Answer:
D. 2 7/12
Step-by-step explanation:
8 1/4 - 5 2/3
Turn to improper fractions.
33/4 - 17/3
Make the denominators equal.
99/12 - 68/12
Subtract the fractions since denominators are equal.
31/12
= 2 7/12
Answer:
(x + 1)(5x - 3)
Step-by-step explanation:
Given
5x² + 2x - 3
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term, that is
product = 5 × - 3 = - 15 and sum = + 2
The factors are + 5 and - 3
Use these factors to split the x- term
5x² + 5x - 3x - 3 ( factor the first/second and third/fourth terms )
= 5x(x + 1) - 3(x + 1) ← factor out (x + 1) from each term
= (x + 1)(5x - 3) ← in factored form
Answer:
x=-2/3 + 2
Step-by-step explanation:
Answer: 3-subject notebook cost $0.67 or 67 cents and the single-notebook cost $0.33 or 33 cents.
Step-by-step explanation:
Let's represent the 3-subject notebook by y and the single-notebook by x.
y has to cost twice as much as x and we can represent that by the equation
y = 2x
We now know that the total cost of the 3-subject notebook and the single-subject notebook has to equal $1.
We can also represent that by the equation and solve for x
2x + x = 1
3x = 1
x = 0.33 $0.33 or 33 cents
If the single-subject is $33 cents then subtract it from a dollar to see how much the 3-subject notebook costed.
1- 0.33 = 0.67
