Probability of x occurring is p(x)=0.05
Probability of y occurring is p(y)=0.02
Given that the two events are mutually exclusive, the probability of the two events occurring will be given by:
P(x or y)=0.05+0.02=0.07
The answer is 0.07

The probability that neither x nor y occurs will be given by:
1-P(x or y)
=1-0.07
0.93

The function rule C = 10n + 26 relates the number of people n who attend a small concert to the cost in dollars C of the concert
Nezavi [6.7K]
This is the concept of functions. We are required to calculate for the total cost of tickets if 27, 39 and 43 people attended a concert whose cost was represented by C=10n+26.
To solve for this we substitute the each values in the function as follows;
When n=27
C(27)=10*27+26=296

When n=39
C(39)=10*39+26=416

When n=43
C(43)=10*43+26
=456

The function f(x) = 2x 1 represents the altitude of a plane, where x is the time in minutes. the function g(x) = x2 − 10 represe
Lostsunrise [7]

To estimate the value for g(10), that means that you have to substitute 10 in every x of g(x), then $g(x) =x^2-10 exists g(10) = 90.

The value of g(10), we have to substitute in every x of f(x), the

f(x) = 2x + 1 exists f(90) = 181

Therefore, the value of f[g(10)] exists 181.

<h3>How to estimate the value of f[g(10)]?</h3>

To estimate the value for g(10), that means that you have to substitute 10 in every x of g(x), then

$g(x) =x^2-10

substitute the value of x = 10

$g(10) = (10)^2-10

simplifying the equation, we get

g(10) = 100 - 10

g(10) = 90

We have the value of g(10), we have to substitute in every x of f(x), then

f(x) = 2x + 1

substitute the value of x = 90

f(90) = 2(90) + 1

simplifying the equation, we get

f(90) = 180 + 1

f(90) = 181

The value of f[g(10)] exists 181.

Therefore, the correct answer is option b) 181.
