Write the exact value solution and an approximation for 10^4x=25
Murrr4er [49]

Answer:

exact value: x= \frac{log25}{4}

approximate: x=0.349485

Step-by-step explanation:

Exact Value:

10^{4x} = 25

log (10^{4x})= log 25

4x = log 25

x= \frac{log25}{4}

Approximate:

x= \frac{log25}{4}

x=1.39794/4\\

x=0.349485

Angles L and M are supplementary. What is the sum of their measures? The sum of the measures of angles L and M is
Reil [10]
Supplementary angles will always add up to 180. If you had a straight line, and you drew another line across that line, the two angles on either side of that line would add up to 180 because a flat line is equal to 180 degrees.

Suppose A and B are independent events. If P(A)= 0.4 and P(B) = 0.85, what is P(A and B)?
dmitriy555 [2]

The value of the P(A∩B) is equal to 0.04.

We have given that,

P(A)= 0.4 and P(B) = 0.85.

We have to determine the  P(A and B)

<h3>What is the formula for Independent Events?</h3>

For Independent Events,

P(A) × P(B) = P(A∩B)

so we have, P(A∩B) = 0.4×0.1

P(A∩B) = 0.04

P(A') = 1 - 0.4 = 0.6

This information can be represented on a Venn diagram as shown below

P(A'∪B) means the union of everything that is not A with everything that is B

P(A'∪B) = 0.06 + 0.54 + 0.04

P(A'∪B) = 0.64
