From the number given is appears the rule is y = 2x + 1
This works for all three:
17 = 2(8) + 1
1 = 2(0) + 1
15 = 2(7)+1

Rule: y = 2x + 1

x = -3 , y = -5
x = 6 , y = 13
x = 8 , y = 17
x = 0 , y = 1
x = 7 , y = 15
x = -4 , y = -7
x = 9 , y = 19

rule: y = 2x + 1

Determine whether the random variable is discrete or continuous. In each case, state the possible values of the random variable

Ilia_Sergeevich [38]

Answer:

(a) Discrete random variable.

(b) Continuous random variable.

Step-by-step explanation:

A random variable assumes distinct values or in a specific interval.

If a random variable assume specific distinct finite set of values, that can be counted, it is known as a discrete random variable.

If a random variable assume values in an interval, that cannot be counted, it is known as a continuous random variable.

(a)

Let the random variable X be defined as the number of customers arriving at a bank between noon and 1 : 00 P.M.

The number of customers arriving at a bank in an hour can be counted and are distinct and finite.

Thus, this is an example of discrete random variable.

(b)

Let the random variable Y be defined as the amount of snowfall.

The amount of snowfall is measured by the thickness of the snowfall. The random variable can assume value in an interval like, 1.5 cm to 3 cm snowfall. There are infinite values in this interval.

Thus, this is an example of continuous random variable.

Morgan is making two cookie recipes. Recipe A calls for one-third less than twice the number of cups of sugar than recipe B call

vredina [299]

Answer:

Step-by-step explanation:

2c-1/3=4 1/6

(1/3 x 2= 2/6)

2c= 3 5/6

(6 x 3 + 5)

2c=23

c=11.5 or 11 1/2

Which expression is equal to the example?

Aloiza [94]

$1-(cosx)^4$ value is $2sin^4-sin^4x$ . Correct option is D) $2sin^4-sin^4x$ .

Step-by-step explanation:

Here we have , expression to evaluate:

$1-(cosx)^4$

⇒ $1-((cosx)^2)^2$

⇒ $1-(1-(sinx)^2)^2$

We know that , $sin^2x = 1-cos^2x$ , putting value in equation $1-(1-(sinx)^2)^2$

⇒ $1-(1+sin^4x-2sin^4)$

⇒ $1-1-sin^4x+2sin^4$

⇒ $-sin^4x+2sin^4$

⇒ $2sin^4-sin^4x$

Therefore , $1-(cosx)^4$ value is $2sin^4-sin^4x$ . Correct option is D) $2sin^4-sin^4x$

A plane has an airspeed of 111 km/h. It is flying on a bearing of 79 degrees while there is a 25 km/h wind out of the northeast

qwelly [4]

Answer: Ground Speed = 91 km/hr, Bearing = 189°

Step-by-step explanation:

Step 1: Draw a picture (see attached) to determine the angle between the given vectors. Notice that I moved the wind vector 180° so the head of the wind vector would line up with the tail of the plane vector. This created an angle of 34° between the plane and wind vectors. Why?
