Answer:she had $63.75 at first.
Step-by-step explanation:
Let x represent the amount of money that she had at first.
kathy spent 3 fifths of her money on a necklace. This means that the amount of money that she spent on the necklace is
3/5 × x = 3x/5
The amount of money remaining would be
x - 3x/5 = 2x/5
She used 2 thirds of the remainder on a bracelet. This means that the amount of money that she spent on the bracelet is 2/3 × 2x/5 = 4x/15
If the bracelet costs $17.00, then
4x/15 = 17
4x = 15 × 17
4x = 255
x = 225/4
x = 63.75
20 and -1: they add into 19 and since a negative times a positive is a negative they multiply to -20
Answer:
a. an independent-samples design.
Step-by-step explanation:
Independent sample design is the one in which samples are selected randomly. It is the observation which is not dependent on any other value. The statistical analysis is based on the assumption that the samples are independent. The study in this scenario is not dependent on any other variable and is based on independent sample design.
Answer:
24:40 or 3:5
Step-by-step explanation:
Boys: 24
All children: 24 + 16 = 40
Boys to total amount of children: 24:40
Simplify: 24:40 = 3:5
First make this:
x/90= 40/100 (percent)
Then cross multiply...(Don't know how to explain so search it up)
90x40= 3600
...then divide (by the remaining number)
3600/100=36 left handed players
