Answer:
Step-by-step explanation:
The spinner should land on whatever color 25% of the time.
25% of 20 = 25/100 * 20 = 500/100 = 5
So the correct answer is the number of times the spinner lands on a color 5 times. Only white does that. All the other colors either go above 5 or below it.
Answer:
White
Step-by-step explanation:
to find the theoretical probability, you just divide the number of times you spin it, which is 20, by how many equal sides the spinner has which is 4.
So therefore you'll do:
20 ÷ 4 = 5
So since that is the same probability as white, the answer is white.
Prove that the equation x^2+px-1=0 for every p has two different solutions
Answer:
To prove: The equation x2+px−1=0 has real and distinct roots for all real values of p.
Consider x2+px−1=0
Discriminant D=p2−4(1)(−1)=p2+4
We know p2≥0 for all values of p
⇒p2+4≥0 (since 4>0)
Therefore D≥0
Hence the equation x2+px−1=0 has real and distinct roots for all real values of p

The geometric series that converges from the listed option is [tex]1+\frac{1}{2} + \frac{1}{4} +\frac{1}{8} ,...[/tex] Option B is correct.
The nth term of a geometric sequence is expressed as;
[tex]a_n=ar^{n-1}[/tex]
a is the first term of the sequencer is the common ration is the number of terms.For a geometric sequence to converge, the modulus of its common ratio must be less than 1 (|r| < 1), otherwise, it diverges.
For the first series given as [tex]\frac{1}{81} + \frac{1}{27} +\frac{1}{9} +\frac{1}{3}+ ,...[/tex]
[tex]r = \frac{1}{27} \div \frac{1}{81}\\r=\frac{1}{27} \times 81\\r=\frac{81}{27} \\r=3 > 1[/tex]
Since the common ratio of the sequence is greater than 1, hence the series diverges.
For the series [tex]1+\frac{1}{2} + \frac{1}{4} +\frac{1}{8} ,...[/tex]
[tex]r=\frac{1/2}{1} =\frac{1/4}{1/2} = \frac{1}{2}[/tex]
Since the common ratio of the sequence is less than 1, hence the series converges.

What is the domain???????
Answer:
H
Step-by-step explanation:
The domain is the values of x in a function.
The graph appears to extend infinitely to the right and left going from the x value 1
From what it looks like the two lines never touch or go over the x value 1 and extend infinitely to the right and left meaning that the values of x of the function are all real numbers but x = 1.
This can be written as {x | x ≠ 1 }
The answer is H

Data were collected on the number of days per week that members visit a certain fitness center. The values varied from 0 to 7, and a distribution of relative frequencies for the values was created. Let the random variable X represent the number of days per week that a member visits. The mean of X is 3.12. Which of the following statements is the best interpretation of the mean
A. Each member visits the fitness center 3 or 4 days per week.
B. The average number of days that each member visits the fitness center is 3.12 days per week.
C. Half the members visit the fitness center 3 days per week or less, and the other half 4 days per week or more.
D. The long-run average resulting from repeated sampling of members of the fitness center will approach 3.12 days per week.
E. For a random sample of members selected from the population, the average number of visits for the sample will be 3.12 days per week.
Answer: D
Step-by-step explanation:
The long-run average resulting from repeated sampling of members of the fitness center will approach 3.12 days per week. Option D is correct.
What is mean?The mean of the values is the ratio of the total sum of values to the number of values.
Here,
Let the random variable X represent the number of days per week that a member visits.
The mean of X is 3.12.
This mean describes that on an average 3.12 day in a week members visit the fitness center, it implies that the long-run average resulting from repeated sampling of members of the fitness center will approach 3.12 days per week.
Thus, the long-run average resulting from repeated sampling of members of the fitness center will approach 3.12 days per week. Option D is correct.

Determine the intercepts of the line.
Step-by-step explanation:
The x-intercept is the value of x when y is 0
So you need to substitute:
0 = 4x + 7
-7 = 4x
-7/4 = x
(-7/4,0)
Similarly, the y-intercept is the value of y when x is 0
So:
y = 4x + 7
y = 4(0) + 7
y = 7

Trevor is fishing from a small boat. His fishing hook is 8 meters below him, and a fish is swimming at the same depth as the hook, 5 meters away. How far away is Trevor from the fish? If necessary, round to the nearest tenth.
A ray from Trevor to the fish is the hypotenuse side of a right triangle with
vertices at Trevor's position, the hook and the fish.
The distance from Trevor to the fish is approximately 9.4 meters.Reasons:
The distance of the hook below Trevor, y = 8 meters
The horizontal distance of the fish from the hook, x = 5 meters
Required:
The distance of the fish from Trevor
Solution:
A line drawn from Trevor's position to the fish, h, then to the hook, x, and
then to Trevor, y, forms a right triangle with the distance from Trevor to the
fish being the hypotenuse side, h.
Therefore, by Pythagorean theorem, we have;
h² = y² + x²Which gives;
h² = 8² + 5²
h = √(8² + 5²) = √(89 ≈ 9.4
The distance from Trevor to the fish given to the nearest tenth , d ≈ 9.4 meters

What is the value of x + y for the system of equations y= 2x - 2 and y= 4x + 6?
Answer:
x= -1
y= 2
Step-by-step explanation:
Notice that when x = 0 the value of y is 2/1 so this line "cuts" the y axis at y= 2
y-intercept = 2/1 = 2
When y = 0 the value of x is 1/-1 Our line therefore "cuts" the x axis at x= -1
x-intercept = 2/-2 = 1/-1 = -1

Select the two pairs of figures that are similar.
Angle measures are rounded to the nearest integer.
The two pairs of figures that are similar are shown in figure 1 and 3.
What is Similar quadrilateral?
Two quadrilaterals are similar when there corresponding angles are equal to each other.
Given that;
In figure 1;
Two triangles are shown.
In figure 2;
One rectangle and other is square.
In figure 3;
Two rectangle are shown.
Now,
Since, Two quadrilateral are similar when there corresponding angles are same.
In the figure 1;
The angles of first triangles = 37° , 53°
So, The third angle = 180 - (37 + 53)
= 90
The angles of second triangles = 37° , 53°
So, The third angle = 180 - (37 + 53)
= 90
Thus, There all angles are equal to each other.
So, These figure are Similar.
And, In figure 2;
One figure is square and other is a rectangle.
So, It is not similar.
And, In figure 3;
Both figure are rectangle.
And, All angles in a rectangle are 90 degree.
Thus, they are similar.
Therefore,
The two pairs of figures that are similar are shown in figure 1 and 3.
