Suppose that P(A|B)=0.2, P(A|B')=0.3, and P(B)=0.7. What is the P(A)? Round your answer to two decimal places (e.g. 98.76).

nata0808 [166]

Answer: $P(A) = 0.23$

Step-by-step explanation:

Given :

$P(A/B) = 0.2$

$P(A/B^{1})=0.3$

$P(B)= 0.7$

$P(A) = ?$

From rules of probability :

$P(A) = P(AnB) + P(A n B^{1})$ ........................... equation *

$P(A n B)$ can be written as $P(A/B)$ x $P(B)$

Also , $P(A/B^{1})$ can be written as $P(A/B^{1})$ x $P(B^{1})$

substituting into equation * , we have

$P(A) = P(A/B)$ $P(B) + P(A/B^{1})P(B^{1})$

since P(B) = 0.7, then $P(B^{1}) = 1 - P(B) = 0.3$

so , substituting each values , we have

$P(A) = (0.2)(0.7) + (0.3)(0.3)$

$P(A) = 0.14 + 0.09$

$P(A) = 0.23$

Last month, Jasmine's family drove to a resort in the mountains. They drove 240 mi. On the first day of the trip. On the second

Monica [59]

Answer:

1000 miles

Step-by-step explanation:

Given the following :

Number of miles driven :

First trip = 240 miles

Second day = 205 miles

Third day = 315 miles

Fourth day; miles driven before arriving at their final destination = 220 miles

Total number of miles driven after 4 days before reaching their destination :

(240 + 205 + 315 + 220) = 980 miles

However, they still haven't reached their destination ;

Using front end estimation :

We can take the total miles recorded and make an estimation based on the first digit of the recorded miles traveled:

In other to estimate 980 using front end estimation : the actual number is replaced with a number with only one nonzero digit (which is the first digit)

Hence,

980 - - - - > we round the digit after 9 either 1 or 0, since it is greater than 4, then it is rounded to and added to the first digit, all subsequent dots are rounded to zero

Hence 980 - - - - > 1000

Hence, estimated miles driven = 1000 miles

Explain how you can use the Triangle Sum Theorem to find the measures of the angles in an equilateral triangle.

IRINA_888 [86]

Answers:

The first blank is 180

The second blank is 60

======================================

The triangle sum theorem basically says that adding up all three angles of any triangle always leads to 180 degrees. So that's why

(angle1)+(angle2)+(angle3) = 180

x+x+x = 180

3x = 180

Divide both sides of that last equation by 3. This is to undo the multiplication of 3 done to x.

3x = 180

3x/3 = 180/3 ... divide both sides by 3

x = 60

Each angle of this equilateral triangle is 60 degrees. In an equilateral triangle, all three sides are the same length. Also in an equilateral triangle, all three angles are the same measure and always 60 degrees.

Solve for x 40+5x>95-4x

prisoha [69]

Steps to solve:

40 + 5x > 95 - 4x

~Subtract 40 to both sides

5x > 55 - 4x

~Add 4x to both sides

9x > 55

~Divide 9 to both sides

x > 55/9

Best of Luck!
