What is the Probability of flipping a coin and landing on heads (unlikely,likely,Equally likely of certain,or impossible)

Answers

Answer 1

Answer:

Equally likely

Step-by-step explanation:

A coin has two sides, heads and tails, so if you flip it, you have a 50% chance to get heads and a 50% chance to get tails. 50% - 50% is an equal ratio, therefore having an equal chance of likelyhood to get heads.

Mean Standard Deviation

City MPG 22.37 4.77

Highway MPG 29.09 5.46


a. The Honda Civic had a rating of 45 highway MPG. What is the probability that your car has a worse highway gas mileage than the Civic?



b. The Lincoln Continental had a rating of 17 city MPG. What percent of cars are likely to have a better city gas mileage than the Continental?

Answers

Answer:

a. 0.0018 = 0.18% probability that your car has a worse highway gas mileage than the Civic

b. 89.06% of cars are likely to have a better city gas mileage than the Continental

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

a. The Honda Civic had a rating of 45 highway MPG. What is the probability that your car has a worse highway gas mileage than the Civic?

For Highway, we have that [tex]\mu = 29.09, \sigma = 5.46[/tex]

This probability is the pvalue of Z when X = 45. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{45 - 29.09}{5.46}[/tex]

[tex]Z = 2.91[/tex]

[tex]Z = 2.91[/tex] has a pvalue of 0.9982

1 - 0.9982 = 0.0018

0.0018 = 0.18% probability that your car has a worse highway gas mileage than the Civic.

b. The Lincoln Continental had a rating of 17 city MPG. What percent of cars are likely to have a better city gas mileage than the Continental?

City means that [tex]\mu = 22.37, \sigma = 4.37[/tex]

This probability is 1 subtracted by the pvalue of Z when X = 17. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{17 - 22.37}{4.37}[/tex]

[tex]Z = -1.23[/tex]

[tex]Z = -1.23[/tex] has a pvalue of 0.1094

1 - 0.1094 = 0.8906

0.8906 = 89.06% of cars are likely to have a better city gas mileage than the Continental

B.
Line r has slope 8 and y-intercept (0, 5).

C.
Line r has slope 5 and y-intercept (0, 2).

D.
Line r has slope 11 and y-intercept (0, 8).

Answers

Answer:

im not that smart but

Step-by-step explanation:

Given that In the coordinate plane line p had slope 8 and y intercept (0,5).

Hence equation of line p is

y = 8x+5 (slope intercept form)

When we dilate p by a factor of 3, we have

we find that slope would remain the same but the y intercept would become 3 times.

Hence new line would be

y = 8x+15

Slope = 8 and y intercept = 15

This line will be parallel to original line.

The line r has slope 8 and y-intercept (0, 9) and the equation of the line is y = 8x + 9 if the line p has slope 8 and y-intercept (0, 5). Line r is the result of dilating line p by a factor of 3 with center (0, 3) option (A) is correct.

What is a linear equation?

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

We have:

p has a slope of 8 and y-intercept (0, 5)

Line r is the result of dilating line p by a factor of 3 with center (0, 3).

Line p is:

y = 8x + 5

The center is not on the line because it does not satisfy the line.

Now dilated line r will have the same slope.

And inetercept = 3+3(5-3)

= 9

Thus, the line r has slope 8 and y-intercept (0, 9) and the equation of the line is y = 8x + 9 if the line p has slope 8 and y-intercept (0, 5). Line r is the result of dilating line p by a factor of 3 with center (0, 3) option (A) is correct.

Step-by-step explanation:

Some useful relations are ...

  A triangle inscribed in a semicircle is a right triangle.

  Acute angles in a right triangle are complementary.

  An inscribed angle is half the measure of the arc it intercepts.

  The sum of arcs around a circle is 360°; 180° around a semicircle.

__

1. Arc DF is twice the marked inscribed angle, so is 126°. Arc FE is supplementary to that, so is ...

  arc FE = 180° -126°

  arc FE = 54°

Alternate solution: arc FE is twice angle D, which is the complement of 63°.

  2(90° -63°) = 2(27°) = 54° = arc FE
