7. A recent report states that 89% of Americans consider themselves above average drivers. A local newspaper is planning on conducting a survey to investigate whether this is true locally. If the newspaper assumes that the 89% claim is true and plans to use the normal approximation to calculate probabilities associated with their sample proportion, which sample size would be most appropriate

Answer:

[tex] \cos( \theta) = \frac{ - \sqrt{} 7}{5} \\ \theta = \cos {}^{ - 1} ( \frac{ \sqrt{} - 7}{5} ) \\ \theta = 58.1 \degree, \: 121.9 \degree, \: 238.1 \degree[/tex]

Answer:

Step-by-step explanation:

take 18 degree as reference angle

using cos rule

cos 18=adjacent/hypotenuse

Answer:

[tex]Width = 14feet[/tex]

Step-by-step explanation:

Given

[tex]Area = 154[/tex]

[tex]Width = 11[/tex]

Required

The length

Area is calculated as:

[tex]Area = Length * Width[/tex]

Make Width, the subject

[tex]Width = \frac{Area}{Length}[/tex]

So, we have:

[tex]Width = \frac{154}{11}[/tex]

[tex]Width = 14feet[/tex]

Answer:

y intercept = 5

Step-by-step explanation:

f(x)=5•(1/6)^x

The y intercept is when x =0

Let x =0

f(0)=5•(1/6)^0      

= 5* 1     = 5

The y intercept is 5

If the question is

f(x)=5•(1/6)x

although I have never seen the question written this way

The y intercept is when x =0

Let x =0

f(0)=5•(1/6)0      

= 5* 0     = 0

The y intercept is 0

Answer:

B.    1

Step-by-step explanation:

The y-intercept occurs at x = 0

therefor the applicable function is

f(x) = -x + 1

at x=0

f(0) = -0 + 1

f(0) = 1

I believe the answer is B) All real numbers

Answer:

Then the probability distribution is:

P(0) = 1/3

P(1) = 4/15

P(2) = 1/5

P(3)  = 2/15

P(4) = 1/15

The expected value for X is:

EV = 1.33...

Step-by-step explanation:

We have a total of 6 marbles in the jar.

The probability of getting a red marble in the first try  (X = 0) is equal to the quotient between the number of red marbles and the total number of marbles, this is:

P(0) = 2/6 = 1/3

The probability of drawing one green marble (X = 1)

is:

First, you draw a green marble with a probability of 4/6

Then you draw the red one, but now there are 5 marbles in the jar (2 red ones and 3 green ones), then the probability is 2/5

The joint probability is:

P(1) = (4/6)*(2/5) = (2/3)*(2/5) = 4/15

The probability of drawing two green marbles (X  = 2)

Again, first we draw a green marble with a probability of 4/6

Now we draw again a green marble, now there are 3 green marbles and 5 total marbles in the jar, so this time the probability is 3/5

Now we draw the red marble (there are 2 red marbles and 4 total marbles in the jar), with a probability of 2/4

The joint probability is:

P(2) = (4/6)*(3/5)*(2/4) = (2/6)*(3/5) = 1/5

The probability of drawing 3 green marbles (X = 3)

At this point you may already understand the pattern:

First, we draw a green marble with a probability 4/6

second, we draw a green marble with a probability 3/5

third, we draw a green marble with a probability 2/4

finally, we draw a red marble with a probability 2/3

The joint probability is:

P(3) = (4/6)*(3/5)*(2/4)*(2/3) = (2/6)*(3/5)*(2/3) = (1/5)*(2/3) = (2/15)

Finally, the probability of drawing four green marbles (X = 4) is given by:

First, we draw a green marble with a probability 4/6

second, we draw a green marble with a probability 3/5

third, we draw a green marble with a probability 2/4

fourth, we draw a green marble with a probability 1/3

Finally, we draw a red marble with a probability 2/2 = 1

The joint probability is:

P(4) = (4/6)*(3/5)*(2/4)*(1/3)*1 = (1/5)*(1/3) = 1/15

Then the probability distribution is:

P(0) = 1/3

P(1) = 4/15

P(2) = 1/5

P(3)  = 2/15

P(4) = 1/15

The expected value will be:

EV = 0*P(0) + 1*P(1) + 2*P(2) + 3*P(3) + 4*P(4)

EV = 1*(4/15) + 2*( 1/5) + 3*( 2/15) + 4*(1/15 ) = 1.33

So we can expect to draw 1.33 green marbles in this experiment.

Answer:

1/14

Step-by-step explanation:

The sectors labeled are B, Y, G, C, P, F, O, V, M, A, D, E, H, and R.

Total number of sectors = 14.

When Victoria spins the spinner 18 times, and it stops at the letter B 10 times.

When Victoria spins the spinner  the theoretical probability that this time it will stop at the letter B = Favourable  outcomes ÷total number of outcomes.

Favourable outcomes =1 and Total number of outcomes = 14.

Hence Theoretical Probability = 1 over 14.

Answer:

  8)  a. chord

  9)  b. radius

Step-by-step explanation:

8) Of the items listed, only a chord and a diameter are segments. A diameter is a chord, so of the two appropriate choices, we prefer the more general answer "chord" .

__

9) Of the segments listed, only the radius has one end point at the center of the circle.

Answer:110 degrees

Step-by-step explanation:

Answer:

D, 225

Step-by-step explanation:

Because this equation already has a1, it's useless to test with that, so instead solve for a2.

You would have a2 - 5a1, which would get you a2 = 5(9) because we already know what a1 is, which is 9. a2 = 45

Now we have a2, which is 45, so now we solve for a3

We would have a3 = 5a2 = a3 = 5(45) which is 225 which is a3

Answer:

A = $45948

Step-by-step explanation:

Given the following data;

Principal = $8000

Interest rate = 6% = 6/100 = 0.06

Time = 30 years

To find the future value, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{100})^{t}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] A = 8000(1 + \frac{6}{100})^{30}[/tex]

[tex] A = 8000(1 + 0.06)^{30}[/tex]

[tex] A = 8000(1.06)^{30}[/tex]

[tex] A = 8000(5.7435)[/tex]

A = $45948
