Answer:
720 miles
Step-by-step explanation:
This is assuming the train continues to move at the same speed.
You can think about the problem in the following way:
The 2 hour journey is split up into x number of 15 minute segments.
2 hours = 120 minutes
120/15 = 8
Therefore, x = 8.
If the journey can be split into 8 15 minute segments, and each 15 minute segment carries it 90 miles, the total distance traveled is given by:
8 * 90 miles = 720 miles
Atlernatively, you can calculate the average speed of the train.
Speed = Distance/Time
So: Speed = 90 miles/15 minutes = 6 miles/minute.
Reusing the above formula, substituting in speed = 6 miles/minute and time = 120

Which situation involves a conditional probability? O A. The probability that you roll a 6 on a number cube B. The probability that you make two free throws in basketball C. The probability that you make a second free throw given that you made the first free throw O D. The probability that you are given a book for your birthday
Answer:
c
Step-by-step explanation:
its conditional because you might not make the first free throw.
The situation that involves a conditional probability is the probability that you make a second free throw given that you made the first free throw.
Thus, option (C) is correct.
Conditional probability refers to the probability of an event occurring given that another event has already occurred.
In this case, the probability of making a second free throw is dependent on the condition that you made the first free throw.
Therefore, the probability that you make a second free throw given that you made the first free throw.

Will every function have a hole? Why or why not?
Answer:
No, not every function will have a hole. This is considered a special case. A typical function is one that can be written as a fraction of two polynomials where the denominator is not zero. In a special case (when there is a hole), a factor may appear in both the numerator and denominator.

Answer:
0 ≤ x ≤ 2 (i assumed that the arrows included 0 and 2).
Step-by-step explanation:
One arrow shows 0 and greater (as it is pointing right) and the other shows 2 and smaller (as it is pointing left). The arrow pointing right has the equation of:
x ≥ 0 (where x is a random number)
The arrow pointing left has the equation of:
x ≤ 2 (where x is a random number)
Assuming that you need to find an equation so that x fits both inequalities, we combine them into one inequality and get:
0 ≤ x ≤ 2

Solve: 2x - 3y = 9 and x + 2y = 1
Answer:
(3, - 1 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 9 → (1)
x + 2y = 1 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = 1 - 2y → (3)
Substitute x = 1 - 2y into (1)
2(1 - 2y) - 3y = 9
2 - 4y - 3y = 9
- 7y + 2 = 9 ( subtract 2 from both sides )
- 7y = 7 ( divide both sides by - 7 )
y = - 1
Substitute y = - 1 into (3) for corresponding value of x
x = 1 - 2(- 1) = 1 + 2 = 3
solution is (3, - 1 )

Evaluate cos 17x/6
ill give brainlist
The value of cos(17π/6) = cos(5π/6) = -√3/2.
Hence, cos(17π/6) evaluates to -√3/2.
To evaluate cos(17π/6), we can use the unit circle and the properties of cosine.
First, let's determine the reference angle.
The reference angle is the acute angle formed between the terminal side of the given angle and the x-axis.
The angle 17π/6 is greater than 2π, which means it completes more than one full revolution around the unit circle.
To find the reference angle, we can subtract 2π (or 12π/6) from 17π/6:
17π/6 - 12π/6 = 5π/6
Now, we can evaluate the cosine of the reference angle (5π/6).
In the unit circle, the reference angle 5π/6 corresponds to the point (cos(5π/6), sin(5π/6)).
The cosine value is represented by the x-coordinate of this point.
For the reference angle 5π/6, the x-coordinate is -√3/2.
Therefore, cos(17π/6) = cos(5π/6) = -√3/2.
Hence, cos(17π/6) evaluates to -√3/2.

Find the value of x in the isosceles triangle shown below
Answer:
The answer is 12
Hope it helps
Answer:
x = 12
Step-by-step explanation:
Since the 2 legs and base angles are congruent the triangle is isosceles.
The line from the vertex to the base is a perpendicular bisector dividing the triangle into 2 right triangles.
Using Pythagoras' identity in either of the 2 right triangles with legs 3 and [tex]\frac{1}{2}[/tex] x , hypotenuse [tex]\sqrt{45}[/tex] , then
([tex]\frac{1}{2}[/tex] x )² + 3² = ([tex]\sqrt{45}[/tex] )²
[tex]\frac{1}{4}[/tex] x² + 9 = 45 ( subtract 9 from both sides ²)
[tex]\frac{1}{4}[/tex] x² = 36 ( multiply both sides by 4 to clear the fraction )
x² = 144 ( take the square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12

In the above figure, m∠P = 125° and m∠Q = (5x)°. If angles P and Q are supplementary angles, what are the value of x and the measure of angle Q?
Answer:
I had the same question and the answer is x = 11, m∠Q = 55°
The value of x is 11 and measure of <Q is 55 degree.
What are supplementary angle?Angles that add up to 180 degrees are referred to as supplementary angles. For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.
We have,
m∠P = 125° and m∠Q = (5x)°.
and, P and Q are supplementary angles.
Using the property of Supplementary Angle
<P + <Q = 180
125 + 5x= 180
5x = 55
x= 11
Thus, the measure of <Q
= 5x
= 55 degree
