Answer:
the length of the stripe is 20.82inches
Step-by-step explanation:
given
height of can = 5in
circumference = 12in
π = 3.142
the circumference of the base = 2πr = 12
radius of base = 1.91in
if the stripe wind once round the can (circumference length), it will start from the radius base to the radius top.
the total length of the stripe = 2radius + circumference of can + height
= 2(1.91) + 12 + 5 = 20.82inches
Answer:
The answer is 4
Step-by-step explanation:
2.7/3.0= 3.6/x
Cross multiply
2.7(x)= 3.6(3.0)
2.7x=10.8
Divide both sides by 2.7
x= 10.8/2.7
= 4
Answer:
- axis of symmetry: x = -3
- root: x = -3
Step-by-step explanation:
As indicated in the example shown, the axis of symmetry is the vertical line through the vertex. That is, its equation is ...
x = <x-coordinate of vertex>
Here, the x-coordinate of the vertex is -3, so the axis of symmetry is ...
x = -3
__
The roots are the x-intercepts, the x-values where the graph touches or crosses the x-axis. When the graph only touches the x-axis, there is only one root. Here, the x-value of the point where the graph touches the x-axis is x = -3.
The root is x = -3.
Answer:
1.83%
Step-by-step explanation:
For the expected value of 4 cases per 1000 children. We can use a formula for Poisson distribution to calculate the probability that none of the 1000 students would contract the flu:
So the probability of this to happens is 1.83%
