Answer:

She plays 60 minutes of basketblall per week.

Step-by-step explanation:

basketball = 100% - 45% - 15% - 10% - 10% = 20%

20% of 300 minutes = 0.20×300 = 60 minutes

She plays 60 minutes of basketblall per week.

Answer:

time spend in basketball=(100-45-15-10-10)%of 300 min

=20% of 300=60min is your answer

There will be approximately $594,311.34 in Nathan's daughter's RESP after 25 years of depositing $940 every 2 months with a 3.99% annual interest rate compounded quarterly.

To calculate the amount in Nathan's daughter's RESP after 25 years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = Final amount (amount in the account after 25 years)

P = Principal amount (amount deposited every 2 months)

r = Annual interest rate (in decimal form)

n = Number of times the interest is compounded per year

t = Number of years

In this case, Nathan deposits $940 every 2 months, so the principal amount (P) is $940. The annual interest rate (r) is 3.99% or 0.0399 in decimal form. Since the interest is compounded quarterly, the compounding frequency (n) is 4. The number of years (t) is 25.

Since Nathan deposits every 2 months, we need to calculate the total number of deposits made over 25 years. There are 12 months in a year, so in 25 years, there will be 25 * 12 = 300 months. However, since Nathan deposits every 2 months, the number of deposits (m) is 300 / 2 = 150.

Now, we can substitute these values into the formula:

A = 940(1 + 0.0399/4)^(4*25)

Calculating the exponent first:

(1 + 0.0399/4)^(4*25) ≈ 2.703236

Now, substituting the calculated exponent and the number of deposits into the formula:

A = 940 * 2.703236 * 150 ≈ $594,311.34

Therefore, there will be approximately $594,311.34 in Nathan's daughter's RESP after 25 years of depositing $940 every 2 months with a 3.99% annual interest rate compounded quarterly.

It's important to note that this calculation assumes Nathan makes the same $940 deposit every 2 months consistently over the 25-year period and does not make any withdrawals from the account during that time. Additionally, the actual amount may vary slightly due to rounding and any potential changes in interest rates over the years.

For me, it helps to ask this question: Does it make sense to apply the midpoint? If it doesn't make sense, then the data is discrete. Otherwise, the data is continuous.

Here's an example:

Let's say we are counting the number of people buying a movie ticket. So the numbers we care about are positive whole numbers 1,2,3,... It doesn't make sense to apply the midpoint to the values 1 and 2 to get 1.5; you can't sell half a ticket. Therefore the variable "number of movie tickets sold" is a discrete variable. There are gaps in the data.

On the other hand, if we were measuring the weight of various coins, then this variable is continuous. It's possible to have any positive number decimal number weight (eg: 2.275 grams perhaps). It makes sense to apply the midpoint to any two weights and get some other weight. We don't have to worry about sticking to whole numbers only. Unlike before, there aren't any gaps and we consider this number set to be dense.

One way you could remember the two is to keep this in mind: If you count it, then it's likely discrete. If you can measure it, then it's continuous.

There are probably exceptions to that rule, but for the most part it holds up I think.

Answer:

b. 12

Step-by-step explanation:

a. You can choose from 4 cities for the first performance, then from 3 cities, then from 2 cities, then the last city.

4 * 3 * 2 * 1 = 24

b. Think of the three performances in California as a unit. Within this unit, you can choose from 3 cities for the first one, then 2 cities for the second one, and finally 1 city for the last one.

3 * 2 * 1 = 6

Now you can have the 3 California performances first, followed by Denver, or Denver first followed by California.

The number of days it will take the crew to lay all the track is; 27 days

The number of miles of track the crew has left to lay after 18 days is; 65 miles

We are given the equation that represents the length L (in miles) that is left to lay after d days as;

L(d) = 189 - 7d

where;

L is length in miles

d is number of days

Thus, the number of days it will take to lay all the tracks is;

Number of days = 189/7

Number of days = 27 days

The length L (in miles) that is left to lay after 18 days is;

L= 189 - 7(18)

L= 189 - 126

L= 65 miles

Complete question is;

A railroad crew can lay 7 miles of track each day. They need to lay 189 miles of track. The length, L (in miles), that is left to lay after d days is given by the following function. L(d) = 189 - 7d​

(How many days will it take the crew to lay all the track?)

(How many miles of track does the crew have left to lay after 18 days?)

Answer:

Step-by-step explanation:

If we consider a triangle with the length of the hypotenuse being equal to 1 and the length of the opposite side = 3x.

However, recall that in a right-angle triangle;

SIne = opposite/hypothenuse

Thus; let the angle facing the opposite be y

Then;

SIn y = 3x/1

Sin y = 3x

Thus, y = arcsin (3x)

Now; to find cos(arcsin 3x)

Recall that:

Cosine = adjacent/hypotenuse

Now, using Pythagoras rule;

\(\mathsf{Adjacent \ side = \sqrt{(hypotenuse)^2 -(opposite^2)}}\)

\(\mathsf{Adjacent \ side = \sqrt{(1)^2 -(3x^2)}}\)

\(\mathsf{Adjacent \ side = \sqrt{1 -9x^2}}\)

cos(arcsin 3x) = cos y = adjacent side/hypotenuse = \(\dfrac{\sqrt{1 -9x^2}}{1}\)

cos(arcsin 3x) = \(\dfrac{\sqrt{1 -9x^2}}{1}\)

The missing part of the question is;

(a) Calculate the percent uncertainty in the distance.

(b) Calculate the percent uncertainty in the elapsed time.

(c) What is the average speed in meters per second?

(d) What is the uncertainty in the average speed?

Answer:

A) 0.0687%

B) 0.0312%

C) 4.389 m/s

D) 0.0044 m/s

Step-by-step explanation:

We are given;

Total Marathon distance = 42.188 km

Uncertain distance = 29m = 0.029 km

Time to complete marathon = 2 h , 40 min, and 13 s = 9613 seconds

Uncertain time = 3 seconds

A) % uncertainty in distance = (uncertain distance/total marathon distance) × 100% = (0.029/42.188) × 100% = 0.0687%

B)% uncertainty in the elapsed time = (elapsed time/total time) × 100% = (3/9613) × 100% = 0.0312%

C)average speed = total distance/total time

Total distance when converted to metres is 42188 m

Thus; average speed = 42188/9613 = 4.389 m/s

D) The percent uncertainty in the average speed is the combination of uncertainties of distance and time.

%uncertainty in speed = % uncertainty in distance + % uncertainty in the elapsed time

%uncertainty in speed = 0.0687% + 0.0312% = 0.0999%

Therefore, the uncertainty in the speed is;

δ_speed = 0.0999/100 × 4.389

δ_speed = 0.0044 m/s

After 4 half-lives, only 1/16th (or 0.0625) of the initial amount of the radioactive isotope will remain.

The amount of a radioactive isotope remaining after a certain number of half-lives can be calculated using the formula:

Amount remaining = Initial amount × (1/2)^(number of half-lives)

In this case, we are given the initial amount as "grams" and we want to find out the amount remaining after 4 half-lives.

So, the equation becomes:

Amount remaining = Initial amount × (1/2)^4

Since each half-life reduces the quantity to half, (1/2)^4 represents the fraction of the initial amount that will remain after 4 half-lives.

Simplifying the equation:

Amount remaining = Initial amount × (1/16)

Therefore, after 4 half-lives, only 1/16th (or 0.0625) of the initial amount of the radioactive isotope will remain.

Answer:

Average time per day = 1.2 hours per day
Average time per day = 72 minutes per day

Step-by-step explanation:

To find Clarence's average time per day, we need to divide the total time he takes to walk the 15.5 miles by the number of days he walks, which is five.

Let's calculate his average time per day:

Average time per day = Total time / Number of days

Since Clarence takes a total of 6 hours to walk the 15.5 miles, we'll divide 6 by 5 to find his average time per day:

Average time per day = 6 hours / 5

Average time per day = 1.2 hours per day

To convert hours to minutes, we'll multiply the average time per day by 60:

Average time per day = 1.2 hours * 60 minutes

Average time per day = 72 minutes per day

Therefore, Clarence's average time per day is 72 minutes.

The angle between 0 degrees and 360 degrees that is coterminal with -240 is 120 degrees

Two angles in standard position are called coterminal angles if they have the same terminal side.

When 360 degrees is added to a given angle or when 360 degrees is subtracted from a given angle, we get an angle that is coterminal with the given angle.

Now,

We are to determine an angle between 0 degrees and 360 degrees that is coterminal with -240

To do this, we will add 360 degrees to the given angle

That is,

-240° + 360° = 120°

Hence, the angle is 120 degrees.
