Answer:

A. There is a 1/4 chance.

Step-by-step explanation:

There are 8 outcomes if a coin is flipped 3 times.

Of these, 4 start with tails.

Since 4 is the denominator here, C (3/8) is out.

Also 4 doesn't have 3 as a factor, so B (1/3) is also out.

After the tails flip, two heads follow.

That's one of four of the combinations starting with tails (THH, THT, TTH, TTT, so D is out, leaving A as our answer! (We would need two for A to work)

What does it mean for a variable to have coefficients that are equal but opposite

barxatty [35]

A coefficient goes before a variable and is a constant. When the coefficients are equal but opposite it means you have an even function.

Multiply and simplify: cos(theta) sin(theta) (csc(theta) + sec(theta))

Marina CMI [18]

Cos(θ)sin(θ)[csc(θ) + sec(θ)]
cos(θ)sin(θ)[csc(θ)] + cos(θ)sin(θ)[sec(θ)]
cos(θ)sin(θ)csc(θ) + cos(θ)sin(θ)sec(θ)
cos(θ) + sin(θ)

Evaluate y = ex + 1 for the following values of x. Round to the nearest thousandth. x = −2, y ≈ x = 1, y ≈ x = 2, y ≈

soldier1979 [14.2K]

The equation is not clear whether it is $y= e^{x+1}$ or $y= e^{x} +1$

for $y= e^{x+1}$

$x=-2$ ⇒ $e^{-2+1}=0.37$
$x=1$ ⇒ $e^{-1+1} = e^{0}=1$
$e^{2+1}= e^{3}=20.10$

for $y= e^{x}+1$

$x=-2$ ⇒ $y=e^{-2}+1 =1.14$
$x=1$ ⇒ $y= e^{1} +1=3.72$
$x=2$ ⇒ $y= e^{2}+1=8.39$

Hint: Most scientific calculators have the template of $e^{( )}$ which you can use to work out the value of y
