Frank has a chance of receiving an A grade in statistics, a chance of receiving an A grade in geology, and a chance of receiving

valentinak56 [21]

Complete Question:

Frank has a 41% chance of receiving an A grade in statistics, a 36% chance of receiving an A grade in geology, and a 23% chance of receiving A grades in both statistics and geology. Find the probability that he receives an A in statistics or geology (or both) Write your answer as a decimal (not as a percentage).

Answer:

The probability that he receives an A in statistics or geology (or both) is:

0.54

Step-by-step explanation:

Probability of receiving an A grade in statistics = 41% or 0.41

Probability of receiving an A grade in geology = 36% or 0.36

Probability of receiving A grades in both statistics and geology = 23% or 0.23

Let S = statistics and p(S) = probability of A grade in statistics

Let G = geology and p(G) = probability of A grade in geology

Let p(S and G) = probability of A grades in statistics and geology.

The probability that he receives an A in statistics or geology (or both) is:

= p(S + G) - p(S and G)

= (0.41 + 0.36) - 0.23

= 0.54

What is the base of the exponent in the function when the function is written using only rational numbers and is in simplest for

tekilochka [14]

The general formula for an exponential function is
$f(x)=b^x$

In this case, b is the base which is any real number greater than 0 and is not 1. Additionally, the domain of an exponential function is all real numbers due to the fact that the exponential function is defined by real numbers. While the range is all real numbers greater than zero.

Trava [24]

Answer:

The answer is 10x - 10y - 9

Step-by-step explanation:

14 - 3 - 20 = -9

2y - 12y = -10y

7x + 3x = 10x

14 + 2y - 3 + 7x - 12y + 3x - 20 = 10x - 10y - 9
