Answer:
The relative frequency of landing on tails is 0.3.
Step-by-step explanation:
The relative frequency of an outcome A is:
The number of trials in which the outcome A happened divided by the total number of trials.
In this problem, we have that:
20 coin tosses, so 20 trials. On 6, it landed on tails.
6/20 = 0.3
This means that the relative frequency of landing on tails is 0.3.
To help solve this problem, create a simple equation.
Let x = weekly allowance.
(x/2) + $4 = $11. Subtract 4 from each side
(x/2) = 7. Multiply each side by 2
x = $14.
Joe's weekly allowance is $14
Answer:
47 bpm
B
Step-by-step explanation:
Draw a trend line (attached).
Reading from the graph, the resting hear rate, in bpm, of a person who exercises an average of 8 hours a week is approximately 47.
The only scatter plot that suggests a linear relationship between x and y is graph B (see second attachment) as the trend line is a straight line.
Answer:
x = 2, 3.
Step-by-step explanation:
<u>Since the equation equals 0, we can determine that:</u>
3x-6=0
-x+3=0
Let's solve 3x-6=0.
<u>Add 6 to both sides of the equation:</u>
3x=6
<u>Divide both sides by 3:</u>
x=2
Let's solve -x+3=0.
<u>Subtract 3 from both sides of the equation:</u>
-x=-3
<u>Divide by -1:</u>
x=3
