What is the Venn diagram?It is defined as the diagram that shows a logical relation between sets.
The Venn diagram consists of circles to show the logical relation.
We have:
Total students in a class = 29
First we have to find the number of students who likes both subject for this we have draw a Venn diagram shown in the picture.
From the Venn diagram number of students who likes both = 7
And number of students likes only math = 14
Hence, the probability will be:
[tex]p = \frac{14}{29}[/tex] ( because total number of students is 29)
or P = 0.4827 or 48.27%
Thus, the probability that a child chosen at random from the class likes math but not history is 14/29 or 0.4827.

An archer releases an arrow with an initial velocity of 20 feet per second at a height of 12 feet. The path the arrow takes can be modeled using the function f(x)=−16x2+20x+12, where f(x) represents the height, in feet, of the arrow and x represents the time the arrow travels in seconds. What is the maximum height, in feet, reached by the arrow? Round your answer to the nearest hundredth if necessary. Do not include units in your answer
Answers
Answer: 18.25
Step-by-step explanation:
The arrow reaches its highest point at the y-value of the turning point. Thus, we need to find the maximum quadratic function.
-16x^2+20x+12
We know that the maximum( or minimum) of a parabola is reached at x= -b/(2a)= -20/ 2(-16)= 18.25
Showing that the object will reach a maximum height of 18.25 feet
