In the equation: log (x) = -0.123, what is the value of x?

1 answer:

6 0

The logarithm of a function log a = x is also expressed as 10^x = a. In this case, we are given log (x) = -0.123. Hence the equivalent function is 10^-0.123 = x; x is equal to 0.7536. the answer to this problem is 0.7536.

Reasoning in a laboratory, the probability a bacterial colony thrives is 70%. The numbers 0 to 6 represent the outcome that a co

Maurinko [17]

Answer:

The probability that exactly half of the colonies will thrive = (1/3) = 0.3333

Step-by-step explanation:

The list of random numbers simulates the out comes of 4 colonies.

Based On the simulation in 6 trails, what is the probability that exactly half of the colonies will thrive?

The probability of an event is given mathematically as the number of elements in the event divided the total number of elements in the sample space.

Noting that the numbers 0 to 6 indicate that a colony thrives and the number 7 to 9 represent that a colony doesn't thrive.

The 6 trials are given as

4285; 3 colonies thrive, 1 doesn't.

6903; 3 colonies thrive, 1 doesn't.

3829; 2 colonies thrive, 2 don't.

7871; 1 colony thrives, 3 don't.

2868; 2 colonies thrive, 2 don't.

5137; 3 colonies thrive, 1 doesn't.

The number of trials where exactly 2 colonies thrive = 2

The total number of trials = 6

The probability that exactly half of the colonies will thrive = (2/6) = (1/3) = 0.3333

Hope this Helps!!!

Find the missing side length leave your answers as radicals in the simplest form.

ira [324]

Answer:

Part 1) $x=\frac{10\sqrt{3}}{3}\ units$

Part 2) $y=5\ units$

Step-by-step explanation:

step 1

Find the value of x

In the right triangle of the figure

$sin(30^o)=\frac{(5\sqrt{3}/3)}{x}$ ---> opposite side angle of 30 degrees divided by the hypotenuse

Remember that

$sin(30^o)=\frac{1}{2}$

substitute

$\frac{1}{2}=\frac{(5\sqrt{3}/3)}{x}$

solve for x

$x=\frac{5\sqrt{3}}{3}(2)$

$x=\frac{10\sqrt{3}}{3}\ units$

step 2

Find the value of y

In the right triangle of the figure

$cos(30^o)=\frac{y}{x}$ ---> adjacent side angle of 30 degrees divided by the hypotenuse

we have

$x=\frac{10\sqrt{3}}{3}\ units$

$cos(30^o)=\frac{\sqrt{3}}{2}$

substitute

$\frac{\sqrt{3}}{2}=\frac{y}{\frac{10\sqrt{3}}{3}}$

$y=(\frac{\sqrt{3}}{2})(\frac{10\sqrt{3}}{3})$

$y=5\ units$
