prisoha [69]

Answer:

d. y = 3/4x - b

Step-by-step explanation:

Use the y = mx + b formula to solve the equation. Plug in the known values in to this. After you have done that, you should get:

y = 3/4x - 1

A coin is rolled three times.find the probability of getting 2 heads

Setler [38]

There are 8 possible outcomes when you throw a coin three times:

$HHH,\ HHT,\ HTH,\ HTT,\ THH,\ THT,\ TTH,\ TTT$

Out of these combination, the ones with exactly two heads are

$HHT,\ HTH,\ THH$

So, 3 combinations out of 8 have exactly two heads. This means that the probability of having two heads with three coin throws is 3/8

What is the equation of the midline of the function f(x) = 5.6sin (2.6x - 4.2) - 9.1?

Iteru [2.4K]

Answer:

$f(x) = -9.1$

Step-by-step explanation:

The midline is set on $f(x) = -9.1$ , when the sine function is equal to zero, eliminating the effect from amplitude. The midline is a horizontal line. Hence, the equation of the midline is:

$f(x) = -9.1$
