Answer: 1/5

Step-by-step explanation:

Answer: D

Step-by-step explanation:

The probability of the coin landing on heads is 50% and the relative frequency of the coin landing on heads is 57%

The sample space of a coin is:

S = {Head, Tail}

The sample size is:

n(S) = 2

The probability of the coin landing on heads is calculated as:

P(Head) = n(Head)/n(S)

So, we have:

P(Head) = 1/2

Express as percentage

P(Head) = 50%

Hence, the probability of the coin landing on heads is 50%

From the question, we have:

Toss = 100

Head = 57

The relative frequency of the coin landing on heads is calculated as:

Frequency = 57/100

Express as percentage

Frequency = 57%

Hence, the relative frequency of the coin landing on heads is 57%

Answer:

4.02°

Step-by-step explanation:

The angle of descent can be obtained using trigonometry ;

Since we have a right angled triangle ;

Let's use the relation:

Sin θ = opposite / hypotenus

Hypotenus = 2.7 miles

1 mile = 5280 feets

2.7 miles = (2.7 * 5280) = 14256 feets

Sin θ = 1000 / 14256

Sin θ = 0.0701459

θ = sin^-1(0.0701459)

θ = 4.0223674

Answer:

$377.86

Step-by-step explanation:

Given: Video game system costs $350, sales tax rate is 796.

To find: Final cost

Solve: Calculating Total Cost. Multiply the cost of an item or service by the sales tax to find out the total cost.

                                           3.5  × 7.96 = 27.86

Add the total sales tax to the Item or service cost to get your total cost.

                                           27.86 + 350 = 377.86

The final cost is $377.86

Answer:

8000 and 12,000

Step-by-step explanation:

Let the amount of money deposited in the 3% account be known as "x"

The amount of money deposited in the 6% account would be "20,000 - x" (aka the remaining amount of money not put into the first account)

3% Interest -> 0.03 *

6% Interest  -> 0.06 *

0.03 * x + 0.06 * (20,000 - x) = 960

0.03x + 1200 - 0.06x = 960

-0.03x = -240

x = 8000

20,000 - x

20,000 - 8000 = 12000

Answer:

A. P = 72 feet, A = 300 square feet

Step-by-step explanation:

✔️Perimeter = sum of all sides of the polygon = 15 + 16 + 17 + 8 + 16 = 72 ft

✔️Area of the polygon = area of a trapezoid = ½(a + b)h

Where,

a = 16 ft

b = 16 + 8 = 24 ft

h = 15 ft

Substitute

Area = ½(16 + 24)15

Area = ½(40)15

Area = 300 ft²

Answer:

Vivian will have to get a loan, and pay back the money she spent with her debit card. If she cannot pay back this loan in time, the interest will grow higher and higher. Using a debit card is NOT good because if you don't have the money for something and you buy it anyway, you'll have to pay back double the money if you miss the deadline for the loan.

The equation of the line that is parallel to y = 3x - 2 and intersects the point (3, 5) will be y = 3x - 4.

Let the equation of the line be ax + by + c = 0. Then the equation of the parallel line that is parallel to the line ax + by + c = 0 is given as ax + by + d = 0.

The linear equation is given below.

y = 3x - 2

The equation of the line that is parallel to the line y = 3x - 2 will be given as,

y = 3x + c

The equation passes through (3, 5), then we have

5 = 3(3) + c

5 = 9 + c

c = - 4

Then the equation of the line will be y = 3x - 4.

Answer:

0.989 = 98.9% probability that Mr. Bateman’s class has more students who pass on the first try

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution, the binomial approximation to the normal and subtraction of normal distributions.

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.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Subtraction of normal distributions:

When two normal variables are subtracted, the mean is the subtraction of the means while the standard deviation is the square root of the sum of the variances.

Among Mr. Adams’s students, 68% pass the driving test on the first try. Sample of 40.

This means that [tex]p = 0.68, n = 40[/tex].

[tex]\mu_A = np = 40*0.64 = 27.2[/tex]

[tex]s_A = \sqrt{40*0.68*0.32} = 2.95[/tex]

74% of Mr. Bateman’s students pass the driving test on the first try. Sample of 50:

[tex]p = 0.74, n = 50[/tex]

[tex]\mu_B = np = 50*0.74 = 37[/tex]

[tex]s_B = \sqrt{50*0.74*0.26} = 3.1016[/tex]

What is the probability that Mr. Bateman’s class has more students who pass on the first try?

This is the probability that B - A is greater than 0.

Distribution B - A:

Mean:

[tex]\mu = \mu_B - \mu_A = 37 - 27.2 = 9.8[/tex]

Standard deviation:

[tex]\sigma = \sqrt{s_A^2 + s_B^2} = \sqrt{2.95^2 + 3.1016^2} = 4.28[/tex]

Probability of being larger than 0:

1 subtracted by the pvalue of Z when X = 0. So

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

[tex]Z = \frac{0 - 9.8}{4.28}[/tex]

[tex]Z = -2.29[/tex]

[tex]Z = -2.29[/tex] has a pvalue of 0.011

1 - 0.011 = 0.989

0.989 = 98.9% probability that Mr. Bateman’s class has more students who pass on the first try
