Answer:

29 candy bars.

Step-by-step explanation:

First, let's find the cost of all of the movie passes:

13 x 9.5 = 123.5

Second, let's find the cost of the 3 gift cards:

25 x 3= 75

Now, let's add the costs up and subtract the total from 250:

123.5 + 75 = 198.5

250 - 198.5 = 51.5

So our total is 51.5 dollars. Now let's divide that by 1.75.

1.75 x 29 = 50.75

Since 1.75 x 30 = 52.5, the greatest number of candy Marcy can be is 29 candy bars.

Step-by-step explanation:

If the train travels at an average speed of 50 Km/h, it would be late by 10 minutes.

Speed is simply referred to as distance traveled per unit time.

It is expressed as:

Speed = distance / time

Given that the train running between two stations 50 Km apart arrives on time if it travels at an average speed of 60 km/h.

The time taken by the train to travel 50 km at an average speed of 60 km/h can be calculated using the formula:

Speed = distance / time

time = distance / speed

time = 50 km / 60 km/h

time = 5/6 hour

Next, if the train travels at an average speed of 50 km/h, the time taken to cover the same distance of 50 km would be:

Speed = distance / time

time = distance / speed

time = 50 km / 50 km/h

time = 1 hour

Now, the difference in time between the two scenarios would be:

time difference = 1 hour - 5/6 hour

time = 1/6 hour

Convert to minutes

time = 1/6 × 60

time = 10 minutes

Therefore, the train would be late by 10 minutes.

Answer: C. At the α=0.05 significance level, they should conclude that more than 50% of adults support the tax increase.

Step-by-step explanation:

Given: Null hypothesis: \(H_0:p=0.5\)

Alternative hypothesis: \(H_a: p>0.5\)

p-value = 0.033

If the p-value is greater than alpha (p > . 05), then we fail to reject the null hypothesis.

If α=0.01 , then p-value > α i.e. we fail to reject the null hypothesis.

Conclusion: Exactly 50% of adults support the tax increase.

If α=0.05 then p-value < α i.e. we reject the null hypothesis.

Conclusion: more than 50% of adults support the tax increase.

Daniel = 207 | Brandon = 196.2

Step-by-step explanation:

Brandon will reach the taco truck first.

• Daniel's time can be found by using the expression 327.6/3 + 489/5, which is 207 seconds.

• Brandon's time can be found by using the expression

327.6^+489^2/3 [Sqaured]

The time taken by Brandon will be 196.2 seconds while Daniel will be 207 seconds.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

In a triangle, the sum of all three angles is 180°.

⊕ Time is taken by Brandon ;

      01) Time taken in sand

             Time = 327.6/3 = 109.2 seconds.

     02) Time is taken on the boardwalk

             Time = 489/5 = 97.8 seconds.

Total time taken by Brandon = 109.2 + 97.8 = 207 seconds.

Estimations of π/4:

100 points: 0.75

1,000 points: 0.768

10,000 points: 0.7819

Step-by-step explanation:

To get an estimate of π/4 you can place random points in the square [0, 1] × [0, 1] and estimate it as the ratio of the points that landed inside the unit circle to the total number of points (because the ratio of the area of the circle to the area of the square is π/4).

We do it for 100 xy points and we get:

Point inside the circle area = 75

Estimation of π/4 = 0.75

\(\pi/4\approx=\dfrac{\text{points inside circle area}}{\text{total points}}=\dfrac{75}{100}=0.75\)

We do it for 1,000 xy points and we get:

Point inside the circle area = 768

Estimation of π/4 = 0.768

\(\pi/4\approx=\dfrac{\text{points inside circle area}}{\text{total points}}=\dfrac{768}{1000}=0.768\)

If we do it fo 10,000 xy points, we get

Point inside the circle area = 768

Estimation of π/4 = 0.768

\(\pi/4\approx=\dfrac{\text{points inside circle area}}{\text{total points}}=\dfrac{7819}{10000}=0.7819\)

The value of π/4 (4 decimals) is 0.7854.

Answer:

  (a) P(t) = 50·17.5^(t/1.5)   or   P(t) = 50·e^(1.9081t)

  (b) P(5) ≈ 695,713

  (c) P'(5) ≈ 1,327,514

  (d) 4.5 hours

Step-by-step explanation:

You want the exponential function that describes bacterial growth from 50 cells to 875 cells in 1.5 hours, the population after 5 hours, and its rate of growth at that time. You also want to know the time at which the population reaches 250,000.

The function that models exponential growth can be written as ...

  population = (initial population)×(growth factor)^(t/period)

where (growth factor) is the population multiplier over the period.

Here, we are given an initial population of 50, and a growth factor of 875/50 = 17.5 in a period of 1.5 hours. This means we can write the function as ...

  P(t) = 50(17.5^(t/1.5))

Note that the exact problem statement values are used, so no rounding is required.

If this is expressed using an exponent with a base of 'e', then we have ...

  P(t) = 50e^(kt)

Comparing this to the above expression, we see ...

  e^(kt) = 17.5^(t/1.5)

  k = ln(17.5)/1.5 ≈ 1.9081 . . . . take natural logs and divide by t

So, ...

  P(t) ≈ 50(e^(1.9081t))

The cell count after 5 hours is modeled as ...

  P(5) = 50·e^(1.9081·5)

  P(5) ≈ 695,713

Differentiating the population function, we have ...

  P'(t) = 50·(1.9081)(e^(1.9081t) ≈ 95.4067e^1.9081t

Then the rate of change of the population at t=5 is ...

  P'(5) = 1.9081·P(5)

  P'(5) ≈ 1,327,514

The time required for the population to reach 250,000 can be found from ...

  250,000 = 50·e^(1.9081t)

  5,000 = e^(1.9081t) . . . . . . . divide by 50

  ln(5,000) = 1.9081t . . . . . . . take natural logs

  t = ln(5,000)/1.9081 . . . . . .divide by the coefficient of t

  t ≈ 4.5

It will take about 4.5 hours for the population to reach 250,000.

Answer:

We can start by finding how many pages Jordayn reads per hour:

Pages per hour = 72 ÷ (1 1/2) = 72 ÷ 3/2 = 48

So, Jordayn reads 48 pages per hour.

To find out how long it would take her to read a 168-page book, we can use the following formula:

Time = Pages ÷ Pages per hour

Time = 168 ÷ 48

Time = 3.5

Therefore, it would take Jordayn 3.5 hours to read a 168-page book, assuming her reading speed remains constant

Step-by-step explanation:

The present value (PV) of the investment today is approximately $2,965.05.

To find the present value (PV) of the investment today, we need to calculate the present value of each individual contribution and then sum them up. We can use the formula for the present value of an annuity to do this calculation.

The formula for the present value of an annuity is given by:

PV = C * [(1 - (1 + r)^(-n)) / r]

Where:

PV = Present Value

C = Cash flow per period

r = Interest rate per period

n = Number of periods

In this case, the cash flow per period (C) is $500, the interest rate per period (r) is 10.5% (or 0.105), and the number of periods (n) is 20 years.

Let's plug in these values into the formula and calculate the present value (PV):

PV = $500 * [(1 - (1 + 0.105)^(-20)) / 0.105]

Using a calculator, we can evaluate the expression inside the brackets:

PV = $500 * [(1 - 0.376889) / 0.105]

Simplifying further:

PV = $500 * [0.623111 / 0.105]

PV = $500 * 5.930105

PV = $2,965.05

Therefore, the present value (PV) of the investment today is approximately $2,965.05.

A one-to-one correspondence between the set of all positive integers and the set of all rational numbers exists.

By definition, any rational number can be expressed as a fraction a/b, where a and b are integers and b is nonzero. Since any positive integer can be expressed as the fraction a/1, each positive integer can be associated with a rational number a/1.

Thus, there is a one-to-one correspondence between the set of all positive integers and the set of all rational numbers. Furthermore, since any rational number a/b can be expressed as the product of a and b, it can also be associated with the product of two positive integers a and b.
