Answer:

(0, -7)

Step-by-step explanation:

The y-intercept is the point on the line where x = 0 (AKA where the line crosses the y-axis).

Here, the y-intercept is literally given within the question as (0, -7).

Answer:

A) -7

Step-by-step explanation:

Since the x value is 0, then that means that whatever number is in the y place is the y intercept. In this case, it's -7, so the y intercept is -7

Answer:

25.047 or roughly 25.

Step-by-step explanation:

I solved it wrong the first time then i double check with wolframalpha and got the correct number.

We know that the area of the tile is 18 $\sqrt{3}$ and it makes a triangle, we also know the base and height. In this case the base is 2 $\sqrt{3}^{x/12}$ and the height is also given which is $\sqrt{3}^{\frac{x}{6} }$ .

Area of triangle = $\frac{bh}{2}$ ,

substituting we will end up with 18 $\sqrt{3}$ =( 2 $\sqrt{3}^{x/12}$ * $\sqrt{3}^{\frac{x}{6} }$ ) / 2

Here is the tricky part $\sqrt{x} = x^{\frac{1}{2} }$ , i totally forgot about that lol.

Simplifying: we will get 18 $\sqrt{3}$ = $3^{\frac{x}{8} }$

Now, in order to find the x, we will need to take the log of both sides.

$log18\sqrt{3} = \frac{x}{8} log3$

Solving for x we end up getting:

$8\frac{log18\sqrt{3} }{log3}$ = x

where x = 25.047.

To be honest I deserve a nobel prize not a brainliest lol.

Good question bro, take it easy.

Suppose you have a random sample of 50 of these animals. What is the probability that the mean life span of the sample group is

katrin2010 [14]

In what I know of this problem and what you told me I think there is a 1/2 chance!

think about it, if the life span is 15 years old with standard deviation of 3 then that means we can have bats from 12~18 years old and the mean of the 50 numbers can be anything between that depending on the results we got. Then half of values in interval 12~18 is over 15 which gives it a 1/2 probability!

Which of the following illustrates the truth value of the following conditional?

insens350 [35]

The truth table for implication of the equations is F F ⇒ T

<h3>What is a truth table?</h3>

A truth table is a mathematical logic table that shows the truth values of different logic statements combined by a given logic rule.

Analysis:

P: 7 +1 is not equal to 0 making P to be false(F)

q: 2+2 is not equal to 5 making q to be false(F)

so for conditional or implication, F F⇒ T
