Step-by-step explanation:
Answer:
I did the test, C was wrong and A is the correct answer
Step-by-step explanation:
A. 31 is the correct answer
It's asking to solve for a1 but I don't really know how, please help.
[tex]C = \frac{1}{4}n( \: a(1) \: + \: a(2) \: ) \\ [/tex]
Multiply sides by 4
[tex]4 \times C = 4 \times \frac{1}{4}n( \: a(1) + a(2) \: ) \\ [/tex]
[tex]4C = n( \: a(1) + a(2) \: )[/tex]
Divided sides by n
[tex] \frac{4C}{n} = \frac{n}{n}( \: a(1) + a(2) \: ) \\ [/tex]
[tex] \frac{4C}{n} = a(1) + a(2) \\ [/tex]
Subtract sides - a (2)
[tex] \frac{4C}{n} - a(2) = a(1) + a(2) - a(2) \\ [/tex]
[tex] \frac{4C}{n} - a(2) = a(1) \\ [/tex]
[tex]a(1) = \frac{4C}{n} - a(2) \\ [/tex]

A bag contains 6 red, 5 yellow, and 3 black marbles. You select one
marble at random. What is the probability that it is a red or black
marble?
Answer:
The probability that it is a red or black marble is 0.6429, or 64.29%
Step-by-step explanation:
Frequentist Probability
The probability of an outcome is defined as the frequency of the number of ways the outcome occurs relative to the number of ways that it could have occurred.
The equation to calculate the probability is:
[tex]\displaystyle P(A)=\frac{m}{n}[/tex]
Where m is the number of ways the event A can occur and n is the total number of ways it could have occurred.
The bag contains 6 red, 5 yellow, and 3 black marbles. If one of them is randomly selected, it can be of any color from a total of n=6+5+3=14
Event A consists of the marble being red or black. It can be taken from m=6+3=9 marbles.
The probability is:
[tex]\displaystyle P(A)=\frac{9}{14}=0.6429[/tex]
The probability that it is a red or black marble is 0.6429, or 64.29%

you have to draw the 2 lines
the solution will be the intersection point of the 2 lines
Answer:
[D] (2,1)
Step-by-step explanation:
Given;
y=2x-3
y=-2x + 5
Solve;
y = 2x - 3 . . . [Equation 1]
y = -2x + 5 . . . [Equation 2]
[Equating 1 and 2]
2x - 3 = -2x + 5
2x + 2x = 5 + 3
4x = 8
x = 8/4 = 2
x = 2
y = 2(2) - 3 = 4 - 3 = 1
y = 1
Solution = (2, 1)
Hence, Answer = [D] (2,1)

A parabola opening up or down has vertex (4, -1) and passes through (-9, -181/12). Write its equation in vertex form
Answer:
y = -1/12(x -4)² -1
Step-by-step explanation:
The vertex form equation for a parabola is ...
y = a(x -h)² +k . . . . . . vertex (h, k); vertical scale factor 'a'
The vertex coordinates are given. To find the scale factor, we substitute the given point.
-181/12 = a(-9 -4)² -1 . . . . . substitute the given values into the equation
-181/12 = 169a -1 . . . . simplify a bit
-169/12 = 169a . . . . add 1
a = -1/12 . . . . . . . multiply by 1/169
The vertex form equation of the parabola is ...
y = -1/12(x -4)² -1
Identify which quadrant contains the terminal side of an angle in standard position with each given degree measure. 75° 120° –30° –200°.
Answer:
75° quadrant 1
120° quadrant 2
-30° quadrant 4
-200° quadrant 2
The measure 75° is in Quadrant I, 120° is in Quadrant II, -30° is in Quadrant IV and -200° is in Quadrant III.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Angles in standard position are measured in a counterclockwise direction from the positive x-axis.
An angle of 75° is less than 90° and lies between the positive x-axis and the positive y-axis, so it is in Quadrant I.
An angle of 120° is greater than 90° and less than 180°, so it is between the positive y-axis and the negative x-axis, which means it is in Quadrant II.
An angle of -30° is equivalent to a 330° angle (360° - 30°) and lies in Quadrant IV because it is less than 360° and greater than 270°.
An angle of -200° is equivalent to a 160° angle (360° - 200°) and lies in Quadrant III because it is greater than 90° and less than 180°.
Hence, the measure 75° is in Quadrant I, 120° is in Quadrant II, -30° is in Quadrant IV and -200° is in Quadrant III.

Answer:
the answer is option B
Step-by-step explanation:
To find dy/dx the equation here is
first multipled by derivative of second + second multipled by derivative of first
y = x*sinx
dy/dx = x * derivative of sinx + sinx * derivative of x
derivative of x with respect to x is 1
derivative of sinx with respect to x is cosx
therefore
dy/dx = x * cosx + sinx * 1
= x * cosx + sinx
