Find x=1 on the graph. Above it is a horiz. blue line that tells us y = 0.

So f(1)=0.

(a) suppose 3 children in a village ages 3, 5, and 7 are vaccinated with the qiv vaccine. what is the probability that at least

murzikaleks [220]

The probability that at least one child among the 3 will get influenza is 0.07.

<h3>Define probability.</h3>

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given,

3 children in a village ages 3, 5, and 7 are vaccinated with the qiv vaccine

Probability that at least one child among the 3 will get influenza

P(at least one child among the 3 will get influenza)

= 1 - P(no one have influenza)

= 1 - (1- 0.0.378)(1-0.017)²

= 1 - 0.93

= 0.07

The probability that at least one child among the 3 will get influenza is 0.07.

The perimeter of the rectangle below is 90 units. find the length of side vy . write your answer without variables.

Salsk061 [2.6K]

The picture in the attached figure

we know that
perimeter of a rectangle=2*[base+height]
base=3y+1
height=2y+3
perimeter=90 units
so
90=2*[(3y+1)+(2y+3)]-----> 90=2*[5y+4]----> 10y+8=90----> y=8.2 units

base=3y+1-----> base=3*8.2+1-----> 25.6 units
height=2y+3----> height= 2*8.2+3---> 19.4 units

the answer is
<span>the length of side vy is (2y+3)-----> 19.4 units</span>
