Answer:

There will be $2288.98 in the account after 6 years

Step-by-step explanation:

We are given that $1750 is put into an account that pays an annual rate of 4.5%  compounded quarterly.

So, Principal = $1750

Rate of interest = 4.5%

No. of compounds per year = 4

Time = 6 years

Formula :[tex]A =P(1+\frac{r}{n})^{nt}[/tex]

Where A = Amount

P = Principal

r = rate of interest

n = no. of compounds per year

t = time

Substitute the values in the formula :

[tex]A =1750(1+\frac{4.5}{400})^{4 \times 6}[/tex]

A=2288.98

Hence There will be $2288.98 in the account after 6 years

There are 35 nickels and 25 dimes in the piggy bank.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let N be the number of nickels in the piggy bank, and let D be the number of dimes. We can set up the following system of equations to represent the given information:

N + D = 60

0.05N + 0.1D = 4.25

The first equation represents the total number of coins in the piggy bank, and the second equation represents the total value of the coins.

To solve this system of equations, we can use the substitution method. First, we solve the first equation for N:

N = 35

Substituting this equation for N into the second equation, we get:

D = 25

Thus, 35 nickels and 25 dimes are in the piggy bank.

Given that the weight of oranges falls in a normal distribution, the empirical rule states that about 68% of oranges should weigh between 3 oz. and 7 oz., which are one standard deviation away from the mean of 5 oz.

The question involves the concept of the empirical rule in statistics. The empirical rule states that for a normal distribution, approximately 68% of data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

In this scenario, the mean weight of the oranges is 5 oz. and the standard deviation is 1 oz. So, oranges that weigh between 3 oz. and 7 oz. fall within 1 standard deviation on either side of the mean. According to the empirical rule, this represents approximately 68% of the data. So, we can conclude that about 68% of the oranges in the orchard weigh between 3 oz. and 7 oz.

Answer: False wouldn't it be -100 dollars if hes buying something. Correct me if im wrong.

Answer:

The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.

I guess that we want to find the expected value in one spin:

number 1: wins $1

number 2: wins $3

number 3: wins $5

number 4: wins $7

number 5: losses $8

number 6: loses $8

The expected value can be calculated as:

Ev = ∑xₙpₙ

where xₙ is the event and pₙ is the probability.

We know that the probability for all the events is 1/6, so we have:

Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0

So the expected value of this game is $0, wich implies that is a fair game.

The question is a probability problem in Mathematics. It requires calculating the expected value of a game based on the potential winnings and losses and their respective probabilities. On average, Ivanna will lose a dollar each time she plays.

The subject matter of this question is a probability problem within Mathematics. One way to approach the problem would be to calculate the expected value of Ivanna's winnings from a single spin of the spinner. Each outcome (1, 2, 3, 4, 5, 6) has an equal chance of being chosen, which is 1/6, because there are 6 equally likely outcomes.

The formula for the expected value is the sum of all potential outcomes multiplied by their respective probabilities. Numerically, this would be (1*$1 + 1*$3 + 1*$5 + 1*$7 - 2*$8) / 6, which equals -$1.

Therefore, on average, Ivanna will lose a dollar each time she plays this game.

We have been given that Ming throws a stone off a bridge into a river below.

The stone's height (in meters above the water), x seconds after Ming threw it, is modeled by [tex]h(x)=-5(x-1)^2+45[/tex].

We are asked to find the maximum that the stone will reach.

We can see that our given equation is in vertex form of parabola [tex]y=a(x-h)^2+k[/tex] with vertex at point (h,k).

We can also see that leading coefficient is negative, so our given parabola is a downward opening parabola and its maximum value be at vertex.

The maximum height will be equal to y-coordinate of vertex.

We can see that vertex of our given parabola is at point (1,45). Therefore, the maximum height will be 45 meters.

The stone that Ming throws off the bridge reaches a maximum height of 45 meters. This is determined by the model equation for the stone's height as a function of time, which is a quadratic or parabolic function, with 45 as the maximum value.

The question specifically concerns a parabolic formula representing the height of the stone thrown off the bridge over time: h(x) = -5(x-1)^2 + 45. This is a standard form of a parabolic or quadratic function, which is used to model the trajectory of an object under the force of gravity. In this form, the 45 at the end of the equation represents the maximum height, in meters, that the stone will reach. Hence, the maximum height that the stone will reach is 45 meters.

The reason is that the graph of the equation is an upside-down parabola, which means it opens downward. Thus, its maximum point, or vertex, is the top point of the graph, which corresponds to the height of the stone when it is at its peak. The equation is shifted such that this maximum point is (x, h(x)) = (1, 45).

w+c must be up to (<=) 41. corn must be less than (<) 28.

Answer:

3

Step-by-step explanation:

If 4 less than 3 times a certain number is 2 more than the number

Let the number be x

First, three times of number is 3x

Then 4 less will be (3x - 4)

Two more than number is (x + 2)

Hence the algebraic equation will be

3x - 4 = x + 2

Now solving this equation

3x - 4 = x + 2

3x - x = 2 + 4

2x = 6

x = 6 / 2

x = 3

Thus the number is 3

To find the numbers Ali picked, we identify the lowest number (11), calculate the highest number using the range (11 + 13 = 24), and confirm that the median (17) fits between these two numbers. Thus, the numbers are 11, 17, and 24.

Explanation:

Ali picked three numbers, and we have been provided with three pieces of information about these numbers: the lowest number was 11, the range was 13, and the median was 17. We can use this information to determine the three numbers Ali picked.

Step 1: Identify the Lowest Number

We know the lowest number is 11. This is our starting point.

Step 2: Determine the Range

The range of a set of numbers is the difference between the highest and the lowest numbers. Since the range is 13, we add this to the lowest number to find the highest number: 11 + 13 = 24. So, the highest number Ali picked is 24.

Step 3: Find the Median

The median is the middle number in a set of numbers that has been arranged in order. We are told the median is 17, which fits perfectly between our lowest and highest numbers, confirming that our calculations are correct.

Therefore, the numbers Ali picked, in order from lowest to highest, are: 11, 17, and 24.

Answer:

A total of 720 elk are likely to be infected

Step-by-step explanation:

we shall be using the proportion by survey to estimate the number of infections

From the survey 8 out of 50 are infected. Thus the likelihood of infection is 8/50

We have 4,500 elk to consider. The number of elk likely to be infected will be 8/50 * 4500 = 720

Based on the sample proportion, it is estimated that approximately 880 elk out of the 5,500 elk in the wildlife preserve are infected with the parasite.

Step 1

To estimate the number of elk likely to be infected with a parasite at a wildlife preserve, we use the sample proportion to project the infection rate to the entire population.

Given:

- Total population of elk [tex]\( N = 5500 \)[/tex]

- Sample size [tex]\( n = 50 \)[/tex]

- Number of infected elk in the sample [tex]\( x = 8 \)[/tex]

First, we calculate the sample proportion [tex]\( \hat{p} \)[/tex]:

[tex]\[ \hat{p} = \frac{x}{n} = \frac{8}{50} = 0.16 \][/tex]

This sample proportion represents the estimated infection rate. To estimate the number of infected elk in the entire population, we multiply this proportion by the total population:

[tex]\[ \text{Estimated number of infected elk} = \hat{p} \times N \][/tex]

Step 2

Substituting the values:

[tex]\[ \text{Estimated number of infected elk} = 0.16 \times 5500 \][/tex]

Performing the calculation:

[tex]\[ \text{Estimated number of infected elk} = 0.16 \times 5500 = 880 \][/tex]

So, approximately 880 elk in the wildlife preserve are likely to be infected with the parasite.

Complete question : Part of the population of 5,500 elk at a wildlife preserve is infected with a parasite. A random sample of 50 elk shows that 8 of them are infected.

How many elk are likely to be infected?

Step-by-step explanation:

Answer:

  2290 mm²  or  2289.94 mm²

Step-by-step explanation:

The radius of the outer circle is the sum of the inner radius and the width of the shaded area: 12.6 mm +17.2 mm = 29.8 mm.

The shaded area is the difference between the area of the outer circle and the area of the inner circle. The area of either circle is given by the formula ...

  A = πr²

so, the area of the ring is ...

  A = π(29.8 mm)² -π(12.6 mm)² = π(888.04 mm² -158.76 mm²)

  A = 3.14(729.28 mm²) = 2289.9392 mm²

The area is about 2289.94 mm², which rounds to 2290 mm².

Final answer:

The situation that can be modeled by a linear function is (3) An amusement park allowing 50 people to enter every 30 minutes.

It represents a scenario with a constant rate of change, suitable for a linear model such as y = 50x.

Explanation:

The situation that can be modeled by a linear function is (3) An amusement park allows 50 people to enter every 30 minutes. This scenario represents a situation where there is a constant rate of change, which aligns with the characteristic of a linear function. In this context, the independent variable represents the time in 30-minute intervals, and the dependent variable represents the number of people allowed to enter. The equation to model this situation could be y = 50x, where y is the total number of people and x is the number of 30-minute intervals that have passed.

Scenarios (1), (2), and (4) represent non-linear relationships. Specifically, (1) involves exponential growth as the bacteria population triples each day, which is a multiplicative rate of change rather than a constant additive rate. (2) Involves exponential decay as the value of a cell phone decreases at a percentage rate annually, and (4) involves exponential decay in the number of teams as the number is halved after each round.
