Your friend decides to flip a coin repeatedly to analyze whether the probability of a head on each flip is one half . He flips t

he coin 15 times and observes a head 6 times. He concludes that the probability of a head for this coin is 6/15 = 0.40 and the coin is not balanced. What is a correct interpretation?
A. Probability doesn't prove anything about the coin because probability is subjective.
B. A coin is balanced as long as the probability of each outcome is closer to 0.5 than it is to 1 or 0.
C. Environmental conditions such as temperature and humidity can cause the results of flipping a balanced coin to be skewed and thus appear unbalanced.
D. In the short run, the proportion of a given outcome can fluctuate a lot. A long run of observations is needed to accurately calculate the probability of flipping heads.

abruzzese [7]

Answer:

88

Step-by-step explanation:

5GP= BP

2BNP= GNP

BP+BNP=333

GP+GNP=225

BNP= 333-BP

BNP= 333-5GP

GP= 225-GNP

GP= 225-2BNP

BNP=333-5(225-2BNP)

BNP=333-1125+10BNP

-9BNP=-792

BNP=88

Hope it helps :)

Best answer or correct answer gets brainliest
Brilliant_brown [7]

Answer: C. x = 6; m∠XOY = 18

Step-by-step:

We see that ZOW and WOX are supplementary, meaning the sum of their angles equal 180.

We also know that WOY is a right angle and equals 90.

Now we can solve

180-108 = 72

90 - 72 = 18

XOY = 18

Because 3x = 18, we know that x = 18 by dividing 18 by 3

Can anyone help me with this
Natalka [10]

F(x) = 2x and G(x) = x^2 + 2

(G - F)(x) just means we subtract the functions from each other.

x^2 + 2 - 2x

Let's rearrange the expression

x^2 - 2x + 2

What is the equation of the line that passes through the point (3,4) and has an undefined slope?
rosijanka [135]

Answer:

The equation of the line that passes through the point (3,4) and has an undefined slope is x = 3

Step-by-step explanation:

  • The slope of the horizontal line is zero
  • The equation of the horizontal line passes through the point (a, b) is y = b
  • All the points on the horizontal line have the same y-coordinates

  • The slope of the vertical line is undefined
  • The equation of the vertical line passes through the point (a, b) is x = a
  • All the points on the vertical line have the same x-coordinates

Let us solve the question

∵ The line has an undefined slope

∴ The line is a vertical line

∵ The equation of the vertical line is x = a, where a is the x-coordinate

   of any point on the line

∵ The line passes through the point (3, 4)

∴ a = 3

∴ The equation of the line is x = 3

The equation of the line that passes through the point (3,4) and has an undefined slope is x = 3
