Answer:

P (x = 0)  1/16 = 0.0625

Step-by-step explanation:

We toss a fair coin 4 times.

HT HT HT HT      4/4   of each if TH TH TH TH etc..

HT HT HT TH     3/4

HT HT TH HT    3/4

HT HT TH TH    1/2

Let X count heads. Find P(X = 0) to nearest ten thousandth (4 decimal places).

P (x = 0)  1/16 = 0.0625

We cna find the average by multiplying a midpoint on one half findings on one side ie) 4/4 x 3/4 x 3/4 x 1/2  = 0.2813

Answer:

Step-by-step explanation:

If you toss the coin 4 times, you get 2 * 2 * 2 * 2 possible outcomes, which is 16 outcomes.

There is only 1 outcome where P(x = 0) is possible and that would be

T T T T

one out of 16 is .0625. So

Answer: P(x = 0 )  = 0.0625

The radius r of a circle is increasing at a rate of 7 centimeters per minute. (a) find the rate of change of the area when r = 1
VikaD [51]
Dr /dt = 7

A = pi r^2

dA / dr = 2pir

dA/dt = dA/dr  * dr/dt = 2pir * 7  = 14pir

when r = 12   rate of change of the area =  14*pi*12  =  168pi

            =  527.79 cm^2 / minute to nearest hundredth

Find the area of a parallelogram with the given vertices. P(-2, -5), Q(9, -5), R(1, 5), S(12, 5)
valentina_108 [34]

Answer:

The area of the parallelogram is 55 square unit.

Step-by-step explanation:

The area of a parallelogram is

A=\frac{1}{2}\times base\times height

It is given that the vertices of the parallelogram are  P(-2, -5), Q(9, -5), R(1, 5), S(12, 5).

Plot these points on a coordinate plane, and draw a perpendicular on PQ from the point R.

From the graph is clear that length of PQ is 11 and the height of the parallelogram is 10. So, the area of a parallelogram is

A=\frac{1}{2}\times 11\times 10

A=55

Therefore the area of the parallelogram is 55 square unit.

Y + 0.5xy = x + 2; x = 1<br> How do you solve for y
vfiekz [6]

Step-by-step explanation:

replace the value of x with 1

y + 0.5 × 1 × y = 1 + 2

do the maths

y + 0.5y = 3

here the value of y is equal to 1. same goes for x, if we have no given value for them.

1.5y = 3

y = 3/1.5

y = 2

A restaurant has a sign by the front door that says, "Maximum occupancy: 75 people."
nikklg [1K]

Answer:

112%

Step-by-step explanation:

The percentage of its capacity is calculated as

Number of people / Maximum Occupancy × 100%

Number of people = 84 people

Maximum Occupancy = 75 people

Hence:

84 people /75 people × 100

= 1.12 × 100

= 112%

Therefore, the percentage of its capacity that is 84 people is 112 %
