Answer:
f(4) = 0
Step-by-step explanation:
f(4) means what is the value of y when x = 4
Now x = 4 is on the x- axis, where y = 0, thus
f(4) = 0
Answer:
4cos4x
Step-by-step explanation:
let's use cos
amplitude=4
period=pi/2
2pi/x=pi/2
x=4
no phase shift
y=4cos4x
pic from desmos
(0,1)(2,7)
slope(m) = (7-1) / (2-0) = 6/2 = 3
y = mx + b
slope(m) = 3
use either of ur points...(0,1)....x = 0 and y = 1
now sub and find b, the y int
1 = 3(0) + b
1 = b
so ur equation is : y = 3x + 1....or 3x - y = -1
The percentage of those asked who favoured exactly one sportsperson is 75.
Given that, 78% of those asked were in favour of at least one of the three sportspersons. 50% of those asked favoured Saina, 30% favoured Dhoni, and 20% favoured Anand. If 5% of those asked favoured all three of them.
We need to find what percentage of those asked favoured exactly one sportsperson.
<h3>What is a Venn diagram?</h3>
A Venn diagram is an illustration that uses circles to show the relationships among things or finite groups of things. Circles that overlap have a commonality while circles that do not overlap do not share those traits. Venn diagrams help to visually represent the similarities and differences between two concepts.
Now, favoured exactly one sportsperson=50+30+20-[(30-50-20-5)+(50-30-20-5)+(20-50-30-5)]
=100+(45-5-65)
=100-25
=75
Therefore, the percentage of those asked who favoured exactly one sportsperson is 75.
