3. We have to calculate the relative frequency of the class "boys who want to go to the water park".
We can calculate the relative frequency as the quotient between the absolute frequency, which in this case is 60, and the total sample size, which is 210.
4. We have to estimate the probability of selecting a girl who wants to go skating.
As this class has an absolute frequency of 45, we can approximate the probability as:
Answer:
3. The relative frequency is approximately 0.29.
4. The probability is approximately 0.21.
Answer:
First choice
Step-by-step explanation:
It passes through (4, 0) and (0, -4)
Slope = (0 - (-4))/(4 - 0) = 4/4 = 1
so y - 0 = 1*(x - 4)
x - y = 4
8x - 8y = 32
First choice
Answer: 4 hours
Step-by-step explanation:
The median number is always in the middle the other numbers have to be equal on both sides 5 is the middle number on the plot 6th graders have 4 dots and 8th graders have 0 dots which means the hourly difference is 4
Answer:
In 54 minutes, it'll be 10:30.
Answer:
m<3 = 66°
Step-by-step explanation:
<3 is an angle with its vertex inside the circle shown in the diagram. This, it's an internal angle.
The measure of an internal angle is equal to half the sum of the measure of the arcs intercepted.
Thus, the equation that shows relationship between <3 and arc WX and arc YZ is shown below:
m<3 = ½(40 + 92)
m<3 = ½(132)
m<3 = 66°
