Can someone please help me!!! ASAP!! SOS!!!.... =( find the following using the given polygon

Phantasy [73]

Answer:
n = 6
a = 6 mm
r = 5.19615 mm
R = 6 mm
A = 93.53 mm2 times $3 = $280.59
P = 36 mm
x = 120 °
y = 60 °

r = inradius (apothem)
R = circumradius
a = side length
n = number of sides
x = interior angle
y = exterior angle
A = area
P = perimeter
π = pi = 3.14159...
√ = square root

The number X of days in the summer months that a construction crew cannot work because of the weather has the probability distri

Ronch [10]

Answer:

a.)The probability of losing no more than ten days next summer is

0.65

b.) The probability that 8 - 12 days will be lost next summer is 0.8

c.) The probability there will be no days lost next summer is 0.

Step-by-step explanation:

The probability distribution for the number X of days in the summer that a construction crew cannot work because of the weather is given below:

x P(x)

6 0.03

7 0.08

8 0.15

9 0.2

10 0.19

11 0.16

12 0.1

13 0.07

14 0.02

a.) To find the probability that no more than 10 days will lost next summer can be found by adding the values of probability of the days lost which are 10 days or less, that is to say we can write

p( x ≤ 10 ) = p(x=6) + p(x =7) + p(x=8) + p(x=9) + p(x=10)

= 0.03 + 0.08 + 0.15 + 0.2 + 0.19

= 0.65

b.) To find the probability that 8 to 12 days will be lost next summer will be given by taking into account and adding the probabilities starting form the probability when 8 days are lost to the probability when 12 days are lost

p( 8 ≤ x ≤ 12) = p(x=8) + p(x=9) + p(x=10) + p(x=11) + p(x=12)

= 0.15 + 0.2 + 0.19 + 0.16 + 0.1

= 0.8

c.) The probability that no days will be lost next summer will be given by

= 1 - ( p(x=6) + p(x=7) + p(x=8) + p(x=9) + p(10) + p(11) + p(12))

= 1 - 1

= 0

The probability that will be no days lost next summer is zero. We can conclude that there will be some days lost next summer.

The student who traveled to states visited new states during a vacation. Does increasing the to change the median? If so, how?

mote1985 [20]

Step-by-step explanation:

The exact question is as follows :

Given - The student who traveled to 3 states visited 6 new states during a vacation.

To find - Does increasing the 3 to 6 change the median? If so, how?

Proof -

Yes,

If we increase the 3 states to 6 states, it changes the median

Because

The median of the first 3 states is the middle state.

For example -

If we have 3 states X, Y, Z

Then the median is the state Y

Now,

The median of 6 states is the average of the 2 middle states.

For example -

If we have 6 states

X, Y, Z, U, V, W

Then

The median is not explicit.

Median is the average of the two middle states, Z and U.

And

Average of Z and U = half of the sum of Z and U.

i.e. (Z + U)/2.

And we can see that,

Median of 3 States is not equal to Median of 6 states

i.e. Y is not equal to (Z + U)/2.

So,

We can say that,

Increasing the state 3 to 6 changes the median.
