Answer:

x = 2

Step-by-step explanation:

(x² logₓ27) log₉x = x + 4

Use change of base formula.

x² (log 27 / log x) (log x / log 9) = x + 4

Simplify.

x² (log 27 / log 9) = x + 4

x² (log 3³ / log 3²) = x + 4

x² (3 log 3 / (2 log 3)) = x + 4

x² (3 / 2) = x + 4

3x² = 2x + 8

3x² − 2x − 8 = 0

(x − 2) (3x + 4) = 0

x = 2 or -4/3

Since x > 0, x = 2.

Answer:

384 cubic meters

Step-by-step explanation:

Think of it as two rectangles on top of each other and then add the two volumes.

Volume is l*w*h

So for the bottom rectangle: (8) (12) (2) = 192 cubic meters

And for the top rectangle: (4)(6)(8) = 192 cubic meters

It is important to remember that for the top box you have to subtract the height of the bottom box which is why I used 4 for the height instead of 6.

Then you add them together.

192+192 = 384 cubic meters

Which statement is true about perpendicular lines?
The lines are in the same plane but never intersect.
The lines intersect at an acute angle.
The lines intersect at a right angle.
The lines are not in the same plane.​

Answers

Perpendicular lines intersect at a 90* angle also known as a right angle.

The statement "The lines intersect at a right angle." is true about perpendicular lines.

What are perpendicular lines?

Perpendicular lines are lines that intersect with other lines at an angle of 90°.

It is asked to find the correct statement about perpendicular lines from the given options.

A line is said to be perpendicular to another line when the angle created between them is a right angle.

This means that the only statement among the given statements that correspond to perpendicular lines is that they intersect at a right angle.

Therefore, we have found that the statement "The lines intersect at a right angle." is true about perpendicular lines.

Answer:

y= 200/6x + 100

Step-by-step explanation:

Process of elimination it can't be y= 2/3x + 100 or y = 2/3x because then for x = 12 y would equal 108, but it was closer to 200. That means it had to be one of the other two, the one without the +100 would also end up being too little.

When a fair 6-sided dice is rolled 10 times, the resulting face values are as
follows: 1, 2, 6, 5, 5, 6, 3, 4, 5, 1. After conducting the experiment, the researcher
claims that P(5) = .30. This is an example of ______
probability.

Answers

Answer:

This is an example of independent probability.

Step-by-step explanation:

Independent events are not affected by previous events, just like the outcome of rolling a dice is not effected by the previous outcome. (The dice has no memory of any kind, what so ever!).

When two events are said to be independent of each other, meaning the probability that one event occurs in no way affects the probability of the other event occurring. Another example of an independent event is when you flip a coin. (The coin has no memory of any kind, what so ever!).

Multiplication Rule: When two events, A and B, are independent, the probability of both occurring is:

P(A and B) = P(A) · P(B)

The dice was cast 10 times. In three occasions a 5 came out, and in 7 occasions another outcome occurred. The probability of the outcome of exactly 3 times a 5 in 10 casts, can be calculated as:

P(5) =(1 / 6)^3 + (5 / 6)^7

P(5) = 0.28

P(5) = .3
