Hey there :)

To find the slope with two points we will need to use the equation  [tex]\frac{y^2-y^1}{x^2-x^1}[/tex]

[tex]x^1[/tex]    [tex]x^2[/tex]       [tex]y^1[/tex]  [tex]y^2[/tex]

( 3 , -20 )  ( 5 , 8 )

Here is what the equation should look like when replaced with the numbers (it will be a fraction) :

                                     [tex]\frac{8 - (-20)}{5 - 3}[/tex]

We know that two negatives cancel out and make a positive, so the numerator would actually be 8 + 20.

Solve the fraction and we get   [tex]\frac{28}{2}[/tex]

28 divided by 2 is 14. The slope is 14.

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

The students spent 5% of their $500 budget on props, calculated by dividing $25 by $500 and then multiplying by 100.

To determine the percentage of the total budget that was spent on props for the student film, we need to use the formula for calculating percentages. The formula is
(amount spent / total budget)
* 100 = percentage spent.

Applying this formula to the given values:

Therefore, the students spent 5% of their total budget on props.

Answer:

(x+4)(x-5)

Step-by-step explanation:

You need to find two numbers that multiply to be -20 but add up to be -1.

Answer:

( x - 5 ) ( x + 4 )

Step-by-step explanation:

When solving quadratic equations it's important to remember that they have 2 solution. We need to work out the factors, sum and the products to successfully factorise the quadratic and solve it. So,

x² - x - 20 = 0

Sum = -1

Product = -20

So we need two numbers that sum to -1 and multiply together to make -20

Factors = -5 and 4

x² - 5x + 4x - 20

Factor x² - 5x and 4x -20 separately

x² - 5x = x ( x - 5 )

4x - 20 = 4 ( x - 5 ) So

x ( x - 5 ) + 4 ( x - 5 )

We can see a common factor of  ( x - 5 ) and the other bracket would be       ( x + 4)

( x - 5 ) ( x + 4 )

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.

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:

2x

Step-by-step explanation:

if x equals the amount of miles per hour, then 2x would equal the amount of miles in 2 hours

First, let us break down 28 hours 36 minutes into minutes.

Number of minutes taken to grade 220 essays = (28 x 60) + 36 = 1680 + 36 = 1716 minutes

Now, we can find the average time taken to grade an essay by dividing the time taken to grade 220 essays by 220.

Average amount of time taken to grade an essay = [tex]\frac{1716}{220}[/tex] = 7.8 minutes, or 7 minutes and 48 seconds

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.
