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 function LaTeX: f\left(x\right)=2\cdot4^xf ( x ) = 2 ⋅ 4 xcan be used to represent an exponential growth curve. What is the
nikklg [1K]

Option B: 4 is the multiplicative rate of change of the function

Explanation:

The exponential growth function is f(x)=2(4)^x

We need to determine the multiplicative rate of change of the function.

First, let us determine the values of function.

x        y

1        8

2       32

3       128

4       512

Since, the multiplicative rate of change of an exponential function is the number by which the next term is increasing or decreasing.

Thus, the multiplicative rate of change of the function is given by

Multiplicative rate of change of the function = \frac{32}{8} =4

Multiplicative rate of change of the function = \frac{128}{32} =4

Multiplicative rate of change of the function = \frac{512}{128} =4

Thus, the multiplicative rate of change of the function is 4

Therefore, Option B is the correct answer.

a car moves 35 miles per hour travels a distance of 51.3 feet each second. about how far does a car travel in 7.1 seconds ?
Sergio039 [100]
If you would like to know about how far does a car travel in 7.1 seconds, you can calculate this using the following steps:

51.3 feet ... 1 second
x feet = ? ... 7.1 seconds

51.3 * 7.1 = x * 1
x = 51.3 * 7.1
x = 364.23 feet

The correct result would be 364.23 feet in 7.1 seconds.
