Answer:

y=5/3x−6

5/3 is your slope

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3y = 5x - 18 ( divide all terms by 3 )

y = \(\frac{5}{3}\) x - 6 ← in slope- intercept form

with slope m = \(\frac{5}{3}\) and y- intercept c = - 6

Answer:

y = -x + 5

Step-by-step explanation:

The equation is y= mx + b

m = the slope or rise/run or (y2 - y1) / (x2 - x1)

b = y-intercept

The slope here is -1, and the y-intercept is 5, so our equation is

y = -x + 5

Answer:

B

Step-by-step explanation:

the 2/3x represents how much it will increase while the -1 represents the y-intercept

3a and 4b are not like terms, hence they cannot be added, and the result of the expression is 3a + 4b and not 7ab.

Like terms are terms that share these two features:

If two terms are like terms, then they can be either added or subtracted.

3a and 4b on this problem are not like terms, as the letters, in this case a and b, are different.

Thus, the expression cannot be simplified, as only like terms, which are terms whose definition we gave in this explanation, can be simplified.

A piecewise function is a function that is defined by different equations on different intervals.

Graphing a piecewise function on a graph is a great way to visualize its behavior and understand its properties. One of the most popular and user-friendly ways to graph piecewise functions is using the online graphing calculator Desmos.

Here is a step-by-step guide on how to graph a piecewise function on Desmos:

Go to the Desmos website

and click on the "Graphing Calculator" button.

On the left side of the screen, you will see a text box labeled "y=". This is where you will enter the equation of your piecewise function. You can enter multiple equations by separating them with commas.

To graph a piecewise function, you will need to enter different equations for different intervals.

For example, if you have a piecewise function that is defined by the equation y = x^2 for x < 0 and y = x + 2 for x ≥ 0, you would enter y = x^2, x < 0 and y = x + 2, x ≥ 0 in the "y=" text box.

Once you have entered your equations, press the "Graph" button to see the graph of your piecewise function on the screen.

If you want to adjust the graph, you can use the sliders on the left side of the screen to change the range of the x- and y-axis. You can also use the buttons at the top of the screen to zoom in and out or pan around the graph.

To see the graph of multiple piecewise functions at once you can use the "Add another equation" button under the "y=" text box to add additional equations.

You can also use the "Table" tab to see the values of the function at certain x-values and also can use the "Slider" tab to change the value of x and see how that effects the graph of the function.

By following these steps, you can easily graph piecewise functions on Desmos and visualize the behavior of the function. Desmos is a great tool that allows you to experiment with different equations and see how they affect the graph of the function.

It is a great way to understand the properties of piecewise functions and to visualize them in multiple ways.

Mean of bagel

Step-by-step explanation:

Working out each of the statically summaries Given in the option :

Mean of muffin :

Mean = Σx / n

n = sample size

(61 + 20 + 32 + 58 + 62 + 61 + 56) / 7

= 350 / 7

= 50

Mean of bagel :

Mean = Σx / n

n = sample size

(34 + 45 + 43 + 42 + 46 + 72 + 75) / 7

= 357 / 7

= 51

Hence, from the result obtained, we could see that the value of 51 summarizes the mean of bagel.

Answer:

The answer is C.

Step-by-step explanation:

As you can see, the line clearly intercepts at the line 0,4.

I really hope this helps!!! Please mark me brainliest!

The solution for question a is 0.7636. The solution for question b is 12.09 hours. The solution for question c is 0.9842. We can show the working in the following manner.

(a) To find the probability that a household views television between 5 and 11 hours a day, we need to find the area under the normal distribution curve between those two values.

We can do this by standardizing the values using the formula z = (x - μ) / σ, where x is the value we're interested in, μ is the mean, and σ is the standard deviation. Then we can use a standard normal distribution table or calculator to find the area.

For 5 hours of viewing: z = (5 - 8.35) / 2.5 = -1.34

For 11 hours of viewing: z = (11 - 8.35) / 2.5 = 1.06

Using a standard normal distribution table, we find that the area to the left of -1.34 is 0.0918, and the area to the left of 1.06 is 0.8554. So the area between -1.34 and 1.06 is:

0.8554 - 0.0918 = 0.7636

Therefore, the probability that a household views television between 5 and 11 hours a day is 0.7636.

(b) To find the number of hours of television viewing that a household must have in order to be in the top 3% of all television viewing households, we need to find the z-score that corresponds to the top 3% of the distribution. We can then use the formula z = (x - μ) / σ to solve for x.

Using a standard normal distribution table, we find that the z-score that corresponds to the top 3% of the distribution is approximately 1.88. Therefore:

1.88 = (x - 8.35) / 2.5

Solving for x, we get:

x = 1.88 * 2.5 + 8.35 = 12.09

Therefore, a household must view at least 12.09 hours of television per day to be in the top 3% of all television viewing households.

(c) To find the probability that a household views television more than 3 hours a day, we need to find the area under the normal distribution curve to the right of 3. We can use the same formula as in part (a) to standardize the value and then use a standard normal distribution table or calculator to find the area.

For 3 hours of viewing: z = (3 - 8.35) / 2.5 = -2.14

Using a standard normal distribution table, we find that the area to the left of -2.14 is 0.0158. So the area to the right of 3 is:

1 - 0.0158 = 0.9842

Therefore, the probability that a household views television more than 3 hours a day is 0.9842.

Answer:

10000

Step-by-step explanation:

Do 10x10x10x10 in a calculator

Answer: 10^4= 10,000

Step-by-step explanation:

10^4= 10*10*10*10= 10,000

To find the expected number of times Joan rolls a 3, we use the formula for mean of a binomial distribution.

The correct option is, option (C) 6.

The probability of rolling a number 3 on any given roll is 1/4

If Joan rolls the die 20 times, the number of times she rolls a 3 will follow a binomial distribution with n = 20 (number of trials) and p = 1/4 (probability of success).

The formula for the probability mass function of a binomial distribution is:

P(X=k) = (n choose k) * p^k * (1-p)^(n-k)

where X is the random variable representing the number of successes (the number of times Joan rolls a 3), k is the number of successes, n is the number of trials, p is the probability of success, and (n choose k) is the binomial coefficient, which represents the number of ways to choose k items from a set of n items.

Using this formula, we can calculate the probability of rolling a 3 exactly k times out of 20 rolls:

P(X=k) = (20 choose k) * (1/4)^k * (3/4)^(20-k)

To find the expected number of times Joan rolls a 3, we can use the formula for the mean of a binomial distribution:

E(X) = n * p

In this case, E(X) = 20 * 1/4 = 5

Therefore, the expected number of times Joan rolls a 3 is 5.

Since the possible answers are integers, the closest answer to 5 is 6. Therefore, the answer is (C) 6.
