Therefore, the statement represents an exponential function.

The given statement, "The value of a coin collection has increased by 3.25% annually over the last 20 years" represents an exponential function.Exponential functions refer to the mathematical operations where a constant is raised to the power of the variable x and this variable is the input, and the exponential function is the output.The given statement represents the exponential function because the value of the coin collection is increasing by 3.25% every year, which means it is compounding. Compounding interest is an essential feature of an exponential function since it increases in a compound way. The formula for compound interest is given as:`A=P(1+(r/n))^nt`Where,A is the final amount,P is the principal amount,r is the annual interest rate,n is the number of times the interest is compounded per year,t is the time in years.The compound interest formula reflects the exponential growth model because of the exponent. Also, the coin collection's value is continuously growing and, the longer it takes, the more its value increases.Therefore, the statement represents an exponential function.

Answer:

m=3

Step-by-step explanation:

Move all terms that don't contain  m  to the right side and solve.

Answer:

m=3

Step-by-step explanation:

Simplifying

18 = 5m + 3

Reorder the terms:

18 = 3 + 5m

Solving

18 = 3 + 5m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-5m' to each side of the equation.

18 + -5m = 3 + 5m + -5m

Combine like terms: 5m + -5m = 0

18 + -5m = 3 + 0

18 + -5m = 3

Add '-18' to each side of the equation.

18 + -18 + -5m = 3 + -18

Combine like terms: 18 + -18 = 0

0 + -5m = 3 + -18

-5m = 3 + -18

Combine like terms: 3 + -18 = -15

-5m = -15

Divide each side by '-5'.

m = 3

Simplifying

m = 3

To write an equation for a parabola with the vertex and y-intercept, the equation of vertex form y=a(x-h)^2+k is used.

What is a parabola?

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves.

Consider an example where vertex is (2,1) and y-intercept is (0,-3).

The equation of parabola needs to be deduced using these points.

The equation of a parabola in vertex form is -

y=a(x-h)^2+k

Here, a is a constant and (h ,k) are the coordinates of the vertex.

So, (h,k)=(2,1)

⇒y=a(x−2)^2+1

To obtain the value of a, substitute (0,−3) into the equation -

-3=4a+1

4a=-4

a=-1

⇒y=-1(x−2)^2+1

Now, distribute and simplify -

y=-1(x−2)^2+1

y=-(x^2-4x+4)+1

y=-x^2+4x-4+1

y=-x^2+4x-3

On, graphing this equation a parabola is obtained.

Therefore, to write an equation of parabola vertex form is used.

The measure of angles are:

3. <1 = 63, <2= 49, <3= 87, <4= 44

4. <1= 52, <2= 79, <3= 38

The total of a triangle's three internal angles is 180 degrees, as stated by the angle sum feature of a triangle. A closed shape with both inner and exterior angles, a triangle is created by three line segments. When the values of the other two angles are known, one can utilise the angle sum property to determine the measure of an unknown interior angle.

3. <3 + 93=1 80 (linear pair)

<3 = 87

<2 = 49 (Vertical opposite angle)

<3 + <4 + 49= 180  (Angle sum property)

87 + <4 + 49= 180

<4 = 44

and, <2 + <1 + 68= 180  (Angle sum property)

49+ <1 + 68= 180

<1 = 63

4. <3 = 38 (alternate interior angle)

<2 + <3 + 63= 180  (Angle sum property)

38+ <2 + 63= 180

<2 = 79

Based on the survey results, a typical parent would spend around $44 on their child's birthday gift, with a margin of error of approximately $2.9 at a 99% confidence level.

To estimate how much a typical parent would spend on their child's birthday gift, we use the sample mean and standard deviation as estimates of the population parameters. The sample mean of $44 serves as the point estimate for the population mean.

To determine the margin of error, we use the standard error, which is the standard deviation divided by the square root of the sample size. In this case, the standard error is approximately $2.5 (standard deviation of $10 divided by the square root of 20). Multiplying the standard error by the critical value corresponding to a 99% confidence level (z-value of 2.58 for a large sample size) gives us the margin of error.

Therefore, the typical amount spent on a child's birthday gift is estimated to be $44, with a margin of error of approximately $2.9. This means that we can be 99% confident that the true mean amount spent by parents falls within the range of $41.1 to $46.9.

Nora could run 7.5 minutes per mile to qualify for the state cross-country championships. The correct answer is option c.

To qualify for the state cross-country championships, Nora needs to run 4 miles in 30 minutes or less. So, her average rate should be:

average rate = total time / total distance

If she runs at the slowest rate possible to still qualify, then her average rate would be:

average rate = 30 / 4 = 7.5 minutes per mile

Therefore, the correct option is c) 7.5.

If she runs slower than this average rate, then her total time would exceed 30 minutes and she would not qualify.

Based on the information provided, the suggested interval (0 < x < 2) could potentially be an interval during which the water balloon's height is increasing.

In general, if the height of the water balloon is increasing, it means that as time progresses, the height of the balloon is getting larger. This corresponds to a positive rate of change of the height with respect to time.

If we have a function that describes the height of the water balloon over time, we can calculate the derivative of that function with respect to time. If the derivative is positive within the interval (0 < x < 2), it means that the height is increasing during that interval.

However, without the specific function or more information, it is not possible to determine with certainty whether the water balloon's height is increasing within the given interval.

Answer:

Step-by-step explanation:

H - Hamburgers ; D - Hot Dogs

First make two equations :

H+D=22 ; since we sold 22 of both in total

4H+2D=64 ; since the total amount of money raised was $64

Now, use elimination to solve

-4(H+D=22) ; multiplying the first equation by -4 so that the H cancels out

-4H-4D=-88 + 4H+2D=64

4H   +2D      =64

-4H    -4D      =-88

-2D=-24

D=12

Then substitute D into an equation

H+12=22

H=10

Checking

4(10)+2(12)=64

40+24=64

64=64

So, the yearbook club sold 12 hot dogs and 10 hamburgers

To approach this type of problem, you have to make a couple of reasonable assumptions - first, that each worker works at the same pace, and second, that the effort to build each wall is the same.

Next, figure out how much effort is required to build one wall. The effort is measured in “working days”. So, how many days does one worker need to build one wall, or how many workers would be required to build one wall in one day? We can calculate this by dividing the 25 worker days used to build five walls by the number of walls (5). So we need five worker days per wall.

(5 workers) x (5 days) = 25 worker-days;

25 worker days/5 walls = 5 worker days per wall.

With 100 workers, it will take five days to build 100 walls. Each worker will build one wall in 5 days. So it will also take 5 days for all 100 workers to build all 100 walls.

100 x 5 = 500 worker days;

500 worker-days / 100 workers = 5 days (answer)

Answer:

Step-by-step explanation:

The probability at least 7 of the puppies will be male is approximately 0.0805 or 8.05%.

To determine the probability that at least 7 of the puppies will be male, we will have to use the binomial probability formula.

P(X ≥ k) = 1 - P(X < k)

where X is the number of male puppies, P is the probability of a puppy being male and k is the minimum number of male puppies required.

We can solve this problem by finding the probability that 0, 1, 2, 3, 4, 5, or 6 of the puppies are male, and then subtracting that probability from 1. We use the binomial distribution formula to find each of these individual probabilities.

P(X=k) = nCk * pk * (1-p)n-k

where n is the total number of puppies, p is the probability of a puppy being male (0.5), k is the number of male puppies, and nCk is the number of ways to choose k puppies out of n puppies. We'll use a calculator to compute each probability:

P(X < 7) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + P(X=6)

P(X = 0) = 11C0 * 0.5⁰ * (1-0.5)¹¹ = 0.00048828125

P(X = 1) = 11C1 * 0.5¹ * (1-0.5)¹⁰ = 0.00537109375

P(X = 2) = 11C2 * 0.5² * (1-0.5)⁹ = 0.03295898438

P(X = 3) = 11C3 * 0.5³ * (1-0.5)⁸ = 0.1171875

P(X = 4) = 11C4 * 0.5⁴ * (1-0.5)⁷ = 0.24609375

P(X = 5) = 11C5 * 0.5⁵ * (1-0.5)⁶ = 0.35595703125

P(X = 6) = 11C6 * 0.5⁶ * (1-0.5)⁵ = 0.32421875

P(X < 7) = 0.00048828125 + 0.00537109375 + 0.03295898438 + 0.1171875 + 0.24609375 + 0.35595703125 + 0.32421875 = 1 - P(X < 7) = 1 - 1.08184814453 = -0.08184814453 ≈ 0.0805
