The y-intercept of 5x+4y=-40 is (0,-10 )

A quadratic equation is expressed in its standard form as y=ax2+bx+c, where x and y are variables and a, b, and c are well-known constants. Substitute 0 for x in a quadratic equation and solve to obtain the y-intercept. The value of c in the equation is always the value of the y-intercept.

Given equation :

5x+4y=-40

To find x-intercept substitute 0 in y and solve for x

5x+4(0)=-40

5x=-40

x=8

so the x intercepts = (8,0)

To find y-intercept substitute 0 in x and solve for y

5(0)+4y=-40

4y=-40

y=-10

here the y-intercepts = (0,-10)

A fair, 6-sided dice is rolled 50 times.

Predict how many times it will land on a number greater than 3.

There are 3 numbers greater than the number 3 are 4, 5, 6.

So, the ratio is 3/6 = 1/2

Then we take 1/2 and multiply by the number of rolls which is 50

1/2 x 50 = 25

So, the answer is C. 25

The probability that the first two marbles will be red and the third one will be blue is 35/2448

The probability of picking a red marble on the first draw is 5/18, and given that the first marble was red, the probability of picking another red marble on the second draw is 4/17 (since there are now only 4 red marbles left out of 17 total marbles).

Finally, given that the first two marbles were red, the probability of picking a blue marble on the third draw is 7/16 (since there are now 7 blue marbles left out of 16 total marbles).

To find the overall probability of this sequence of events, we multiply the probabilities of each individual event.

Therefore, the probability of picking two red marbles and one blue marble in this specific order is:

(5/18) × (4/17)× (7/16)

= 0.0285

Therefore, the probability of this specific sequence of events is 0.0285

The number of flies there will be on the 9th night is 26,244.

On the night 1, there are four flies that come to eat the leftovers. Because the number of flies triples each night after, we can use exponential growth to find the number of flies on each night.

It can be found using the formula:

Flies on night n = 4×3ⁿ⁻¹

Therefore we plug in 9 for n to calculate the number of flies on the 9th night:

Flies on night 9 = 4×3⁹⁻¹

Flies on night 9 = 4×3⁸

Flies on night 9 = 4×6,561

Flies on night 9 = 26,244 flies on the 9th night.

The probability that the sample mean of 128 adults is more than 70.3 kilogrammes is about 0.08%.

We can utilise the Central Limit Theorem to tackle this problem, which stipulates that given a high sample size, the distribution of sample means will be approximately normal, regardless of the form of the population distribution. The sample means' mean will equal the population mean, and the sample means' standard deviation (also known as the standard error) will equal the population standard deviation divided by the square root of the sample size.

Given that the population mean is 68 kilogrammes and the population standard deviation is 10 kilogrammes, the chance that the sample mean of 128 adults is more than 70.3 kilogrammes must be calculated.

To begin, we first compute the standard error of the sample means:

Standard Error = Standard Deviation of the Population / Sample Size

= 10 / √128

= 0.8839

The z-score formula may then be used to calculate the z-score corresponding to a sample mean of 70.3 kilogrammes:

(sample mean - population mean) / standard error = z

= (70.3 - 68) / 0.8839

= 3.15

We may calculate the likelihood that the z-score is greater than 3.15 using a conventional normal distribution table or a calculator. Because the standard normal distribution is symmetrical, the likelihood of the z-score being more than 3.15 is the same as the likelihood of the z-score being less than -3.15.

According to a conventional normal distribution table, the probability associated with a z-score of -3.15 is roughly 0.0008.

As a result, the chance that the sample mean of 128 adults is more than 70.3 kilogrammes is roughly 0.0008, or 0.08%.

To solve this problem, we can use the Central Limit Theorem, which states that for a large sample size, the distribution of sample means will be approximately normal, regardless of the shape of the population distribution. The mean of the sample means will be equal to the population mean, and the standard deviation of the sample means (also known as the standard error) will be equal to the population standard deviation divided by the square root of the sample size.

Given that the population mean is 68 kilograms and the population standard deviation is 10 kilograms, we need to calculate the probability that the sample mean of 128 adults is greater than 70.3 kilograms.

First, we need to calculate the standard error of the sample means:

Standard Error = Population Standard Deviation / √Sample Size

= 10 / √128

Next, we can use the z-score formula to find the z-score corresponding to a sample mean of 70.3 kilograms:

z = (sample mean - population mean) / standard error

Answer:

Step-by-step explanation:

Notice how each congruent square is divided into four equal parts. Since each square has four parts and there are four squares, there are \(16\) of these parts in total. Because each of these parts make up \(\frac{1}{4}\) of each square, all parts are equal. Therefore, you can count the total number of shaded parts to get your percentage.

The top left and bottom right both have one part shaded each for a total of \(2\) parts.

The top right and bottom left have \(0.5\) and \(1.5\) parts shaded, respectively, for a total of \(2\) parts.

Therefore, in total, there are \(2+2=4\) parts shaded out of \(16\) total parts.

Thus, the percentage of the total area that is shaded is:

\(\frac{4}{16}=\frac{1}{4}=\fbox{$25\%$}\).

To calculate the probability that at least two people in a class of 30 share the same birthday, we can use the complement rule, which states that the probability of an event happening is equal to one minus the probability of the event not happening.

If we assume that birthdays are uniformly distributed throughout the year (i.e., each day is equally likely to be someone's birthday), then the probability that no two people in the class share the same birthday is:

365/365 * 364/365 * 363/365 * ... * 336/365

This is because the first person can have any birthday (probability of 365/365), the second person must have a different birthday (probability of 364/365), the third person must have a different birthday than the first two (probability of 363/365), and so on, up to the 30th person, who must have a different birthday than the first 29 (probability of 336/365).

Calculating this probability gives us:

(365/365) * (364/365) * (363/365) * ... * (336/365) ≈ 0.2937

So the probability that no two people in the class share the same birthday is approximately 0.2937.

Using the complement rule, the probability that at least two people in the class share the same birthday is:

1 - 0.2937 = 0.7063

Therefore, the probability that at least two people in a class of 30 share the same birthday is approximately 0.7063, or 70.63%.

According to the question we have  approximately 99.74 percent of customers are willing to pay between $1.20 and $1.80 for a pint of frozen yogurt.

To answer this question, we will use the normal distribution formula and z-score.

First, we need to find the z-score for the lower limit of $1.20:

z = (1.20 - 1.50) / 0.10 = -3

Next, we need to find the z-score for the upper limit of $1.80:

z = (1.80 - 1.50) / 0.10 = 3

Now, we can use a z-table to find the area under the curve between these two z-scores.

The area to the left of z = -3 is 0.0013, and the area to the left of z = 3 is 0.9987.

To find the area between these two z-scores, we subtract the area to the left of z = -3 from the area to the left of z = 3:

0.9987 - 0.0013 = 0.9974

Therefore, approximately 99.74% of customers are willing to pay between $1.20 and $1.80 for a pint of frozen yogurt.
