Check the picture below.

if you check your Unit Circle, it'd be there.

The answer is 1/2 because it is asking for the x value as in : (1/2, sqrrt3/2) (x,y)

Suppose that the die is rolled twice, rather than once. find the probability of rolling an even number on at least one die. find

puteri [66]

We know P = 1/2

X~B(2, 0.5)
n = 1

2C1 from pascal triangle = 2

P(X=0.5)= 2C1 x 0.5 x 0.5

= 0.5
= 50%

Answer : w = (-36)
By transposition method -6 when transposed to the other side it becomes multiplication which will be w = 6*(-6)
= w = (-36)

Margie has 5 times as many nickels as quarters. She has a total of $2.00.

stich3 [128]

Answer:

Part A:

n = 5q (1st equation)

0.05n + 0.25q = 2 (2nd equation)

Part B:

q = 4 ⇒ n = 5 * 4 = 20

Part C:

Margie has 20 nickels and 4 quarters, for a total of $ 2.00

Step-by-step explanation:

Let's recall that a nickel has a value of $ 0.05 and a quarter a value of $ 0.25.

Let n represent the number of nickels and q represent the number of quarters.

Part A:

Write a system of equations to represent the situation.

n = 5q (1st equation)

n * 0.05 + q * 0.25 = 2

0.05n + 0.25q = 2 (2nd equation)

Part B:

Replacing n in the 2nd equation to solve for q:

0.05n + 0.25q = 2

0.05 * 5q + 0.25q = 2

0.25q + 0.25q = 2

0.5q = 2

q = 2/0.5

q = 4 ⇒ n = 5 * 4 = 20

Part C:

Margie has 20 nickels and 4 quarters, for a total of $ 2.00

Help ASAP!! Using the graphed function above, find the following

Alenkinab [10]

Answer:

Maximum: 1, Minimum: -3, Midline y = -1, Amplitude = 4, Period = $\pi$ , Frequency $\displaystyle =\frac{1}{\pi}$ , equation : $f(x)=-4cos(2x)+1$

Step-by-step explanation:

Sinusoid Functions

It refers to the oscillating functions like the sine or cosine which range from a minimum and maximum value periodically.

The graph shown can give us all the information we need to answer these questions:

Maximum: 1

Minimum: -3

The midline goes through the center value (mean) of the max and min values, i.e.

Equation of the midline:

$\displaystyle y=\frac{1-3}{2}=-1$

Amplitude is the difference between the maximum and minimum values

$A=1-(-3)=4$

The period is the time it takes to complete a cycle. We can see the minimum value is first reached at x=0 and next at $x=\pi$

Thus the period is

$T=\pi$

The frequency is the reciprocal of the period:

$\displaystyle f=\frac{1}{T}=\frac{1}{\pi}$

The angular frequency is

$\displaystyle w=2\pi f=\frac{2\pi }{\pi}=2$

The equation of the function is a negative cosine (since it starts at the minimum) or a shifted sine or cosine. We'll choose the negative cosine, knowing all the parameters:

$f(x)=-4cos(2x)+1$
