Answer:
Relative frequency of selecting a 2 = 8/50 = 0.16
Relative frequency of selecting a 3 = 14/50 = 0.28
Step-by-step explanation:
When we have a given experiment with given outcomes (such that each time that we perform the experiment, one outcome happens) the relative frequency of a given outcome is the quotient between the number of times that that outcome happened, and the total number of times that the experiment was performed.
Here the experiment is selecting a random number between 1 and 5, and it is performed 50 times.
Out of these 50 times, the outcome "2" appears 8 times.
Then the relative frequency of selecting the number 2 is:
f(2) = 8/50 = 0.16
And of these 50 experiments, the outcome "3" appears 14 times.
Then the relative frequency of selecting the number 3 is:
f(3) = 14/50 = 0.28
Answer:
B
Step-by-step explanation:
4x-5y=2 ...(1)
10x-21y=10 ...(2)
(1)+2(2) gives
24x-47y=22
Answer: Darla would have to pay $17.69 before tax
Step-by-step explanation:
Total amount in Darla's wallet = $15
She intends buying 2 gallons of fruit, 3 bags of chips and a box of cupcakes.
For the gallon of fruit
The first gallon of fruit cost $3.50
The second gallon of fruit has a discount of 50%. We have
(50/100) * 3.50
= $1.75
Therefore, the total amount for the two gallons of fruit =$3.50 + $1.75
= $5.25
Bag of chips
2 bags of chips cost $5 while 1 bag of chips cost $2.65
Since she intends to buy 3 bags of chips we have $5 + $2.65 = $7.65
1 box of cupcakes = $4.79
The total amount Darla is to pay for the groceries before tax equals
$5.25 + $7.65 + $4.79
= $17.69
This is more than the amount Darla has in her wallet
There are 400 candies in the machine.
Step-by-step explanation:
Given,
Number of red candies in machine = 104
This represents 26% of the total candies.
Let,
x be the total candies in the machine.
According to statement;
26% of x = 104
Dividing both sides by 0.26
There are 400 candies in the machine.
