Answer:
Mean speed is 55.7 mph.
Step-by-step explanation:
The provided frequency distribution is:
Speed Cars
30-39 4
40-49 19
50-59 50
60-69 15
70-79 12
The formula to compute the mean for the grouped data is:
Here, m is mid point and f is frequency.
The mean speed can be computed as:
Thus, the mean speed is 55.7 mph.
Answer:
The length is 6, and the width is 4.
Step-by-step explanation:
The length and width add up to 10. 6 + 4 = 10.
A quarter of the width plus the length = 7. A quarter of 4 = 1. 1 + 6 = 7
Answer:Yes, it is a function
Explanation:The relation is obtained by squaring the value of x and then adding 3.
This means that the equation would be:
y = x² + 3
Now, taking a look at this equation, we would find that each value of x would have only one value of y.
Since a function is defined as a relation in which each x-value has only one y-value, therefore, the given equation represents a function.
This can be illustrated more by graphing the given relation (graph is shown in the attached image).
You will find a parabola is formed where each x value has only one corresponding y-value.
