Answer:

15/4

Step-by-step explanation:

to find the slope with two coordinates use

y2 - y1 / x2 - x1

first find the difference between the ys

the 2nd y point is 5, and the 1st y point is -10, so subtract them from each other

5 - (-10) = 5 + 10 = 15

then find the difference between the xs

the 2nd x point is -1, and the 1st x point is -5, so subtract them from each other

-1 - (-5) = -1 + 5 = 4

now put the difference in ys over the difference in xs

15 / 4

So thats your slope

The area under the standard normal curve where P(-0.88 < Z < 0) is 0.3106. The area under the standard normal curve where P(Z > 0.77) is 0.2207. Option (1)

In probability theory, the standard normal distribution is a normal distribution of a random variable with mean 0 and standard deviation 1. The area under the standard normal curve can be calculated using tables or software.

For the first question, we are given P(-0.88 < Z < 0) and we need to find the area under the standard normal curve that corresponds to this probability. Using a standard normal distribution table, we can look up the values of -0.88 and 0 and find the corresponding areas, then subtract the smaller area from the larger area to get the answer. The correct answer is 0.3106.

For the second question, we need to find the area under the standard normal curve that corresponds to P(Z > 0.77). Since the standard normal distribution is symmetric, we can find the area to the left of 0.77 and subtract it from 1 to get the answer.

Again, using a standard normal distribution table, we can look up the value of 0.77 and find the corresponding area, then subtract it from 1. The correct answer is 0.2207.

Answer:

The puck traveled a distance of 5.38 meters or 5,380 meters

Step-by-step explanation:

Here, we want to know the distance the puck traveled.

The distance from the player’s current location to the opponent’s is 55 meters

Since there are 100 centimeters in a meter, then

55 m= 55 * 100 = 5,500 centimeters

Now, we are told that the puck landed just 120 cm from the opponent’s goal

The distance traveled by the puck will be;

5,500 cm - 120 cm = 5,380 cm

The puck traveled a distance of 5,380 cm or 5.38 meters (5,380 cm to meters is calculated by just dividing by 100)

The initial population of the bacteria culture is 200 bacteria.

The initial population of the bacteria culture can be determined using the equation for exponential growth: P(t)=P0(1+rt), where P(t) is the population after time t, P0 is the initial population, and r is the relative growth rate.

In this case, after 2 hours, the population is 600 and after 8 hours the population is 75,000. Plugging in the values, we get P0 = 600/(1+2*r), or P0 = 600/3. Thus, the initial population of the bacteria culture is 600/3 = 200 bacteria.

Exponential growth is a function of time and rate of growth. It is often used to model population growth or decay, such as in this case. The equation for exponential growth states that the population at any time is equal to the initial population multiplied by the rate of growth at each unit of time.

In this case, the rate of growth (r) is constant over the time period, so the population can be determined by putting in the values for P(t) and P0 and solving for r. Then, using the same equation, the initial population (P0) can be determined.

This leads to the incorrect conclusion that the food is safe for consumption when it is actually not.

A food inspector's job is to inspect samples of food products to determine if they are safe for consumption. In this context, we can consider this process as a hypothesis test with the following hypotheses:

Null hypothesis (H0): The food is safe.
Alternative hypothesis (H1): The food is not safe.

The statement given - "The sample suggests that the food is safe, but it actually is not safe" - describes a situation where the food inspector incorrectly concludes that the food is safe when it is not. This is an example of an error in hypothesis testing.

There are two types of errors in hypothesis testing: Type I and Type II.

Type I error occurs when the null hypothesis is rejected when it is actually true. In other words, a Type I error leads to the false conclusion that the food is not safe when it actually is safe.

Type II error occurs when the null hypothesis is not rejected when it is actually false. In this case, a Type II error results in the false conclusion that the food is safe when it actually is not safe.

Given the statement, "The sample suggests that the food is safe, but it actually is not safe," we can determine that this is an example of a Type II error. The food inspector failed to reject the null hypothesis (that the food is safe) when it was, in fact, false.

The absolute maximum and minimum values of the function f(x, y) = x^2 + y^2 - 2y on the set R = {(x, y): x^2 + y^2 ≤ 9} can be found by analyzing the critical points and the boundary of the region R.

To find the critical points, we take the partial derivatives of f(x, y) with respect to x and y, and set them equal to zero. Solving these equations, we find that the critical point occurs at (0, 1).

Next, we evaluate the function f(x, y) at the boundary of the region R, which is the circle with radius 3 centered at the origin. This means that we need to find the maximum and minimum values of f(x, y) when x^2 + y^2 = 9. By substituting y = 9 - x^2 into the function, we obtain f(x) = x^2 + (9 - x^2) - 2(9 - x^2) = 18 - 3x^2.

Now, we can find the maximum and minimum values of f(x) by considering the critical points, which occur at x = -√2 and x = √2. Evaluating f(x) at these points, we get f(-√2) = 18 - 3(-√2)^2 = 18 - 6 = 12 and f(√2) = 18 - 3(√2)^2 = 18 - 6 = 12.

Therefore, the absolute maximum value of f(x, y) is 12, which occurs at (0, 1), and the absolute minimum value is also 12, which occurs at the points (-√2, 2) and (√2, 2).

Answer:

slope = 9 y-intercept = -5/2

Step-by-step explanation:

since slope form is y=mx+b we know that m= slope and b=y-intercept. since 9 is in place of the m that shows that 9 is the slope. since 5/2 is in the b place you would think the y-intercept would be 5/2 but since the equation is - 5/2 instead of + 5/2 it would be + (-5/2) making the y-intercept negative. hope this helped. :)

Answer:

Step-by-step explanation:

(x + 2)(x +9)= x*(x +9) + 2*(x +9)

                   = x*x  + x*9  + 2*x + 2*9

                   = x² + 9x + 2x + 18   {Combine like terms}

                    = x² + 11x  +18

Answer:

x^2 + 11x + 18

Step-by-step explanation:

I assume this is asking about (x+2)(x+9), so if it isn't, then I can't be sure this is right.

That said, the distributive property has to do with multiplication of things in parentheses, meaning you must multiply this expression out to get what the question is asking. When it comes to 2 binomials, you can use the common abbreviation First Inside Outside Last, or FOIL.

Multiply the First terms: x * x = x^2

Multiply the Outside terms: x * 9 = 9x

Multiply the Inside terms: 2 * x = 2x

Multiply the Last terms: 2 * 9 = 18

This leaves you with x^2 + 9x + 2x + 18. Combine your like terms (9x and 2x) to get x^2 + 11x + 18 and you're done!

Prior to placing an order to buy ABCD stock at a lower price, the investment adviser must conduct thorough research and analysis, set a target price, and determine an appropriate entry point for the purchase.

The investment adviser's primary responsibility is to act in the best interest of their client and make informed investment decisions. In this case, where the adviser believes ABCD stock is appropriate only if the price falls to $35 per share, several steps need to be taken before placing an order.

Firstly, the adviser should conduct comprehensive research on ABCD stock to understand its historical performance, financial health, industry trends, and any relevant news or events that might impact its future prospects. This research will help validate the adviser's belief that the stock is worth considering at a lower price.

Secondly, the adviser should establish a target price of $35 per share based on their analysis and the client's investment objectives. This target price serves as a reference point and provides a clear criterion for initiating the purchase.

Lastly, the adviser needs to identify an appropriate entry point for the purchase. This involves monitoring the stock's price movements and market conditions closely. The adviser may choose to set a limit order at $35 per share or implement a strategy to take advantage of potential price declines, such as dollar-cost averaging.

By following these steps, the investment adviser ensures that they have thoroughly evaluated the investment opportunity and have a plan in place before placing an order to buy ABCD stock for the client's account.

Therefore , the solution of the given problem of fraction comes out to be 4/5 - 2/3 equals 2/15.

Any arrangement of portions or pieces of similar sizes can symbolize a whole. Standard English refers to quantity as "a fraction" in a specified measure. 8, 3/4. Wholes also include fractions. The ratio of the divisor compared to the ratio is used in mathematics to represent numbers. These are all illustrations of fundamental fractions that split by whole numbers.

Here,

You must identify a common denominator for the two fractions in order to subtract fractions with distinct denominators.

Finding the least common multiple (LCM), which is 15 for the denominators 5 and 3, is one approach to accomplishing this.

After that, you can change both numbers so that their numerator is 15:

=> 4/5 = (4/5) x (3/3) = 12/15

=> 2/3 = (2/3) x (5/5) = 10/15

Since both fractions now have the same denominator, you can simplify the sum by removing their numerators:

=> 12/15 - 10/15 = 2/15

Because of this, 4/5 - 2/3 equals 2/15.

To determine the number of students who took the test, we need to count the stems in the stem-and-leaf diagram. From the given diagram, we can see that there are 4 stems: 6, 7, 0, and 9. Each stem represents a ten's place value, so there are 10 students for each stem. Therefore, the total number of students who took the test is:

4 stems × 10 students per stem = 40 students

To find the lowest score on the test, we look at the smallest leaf value in the diagram, which is 1. However, since the smallest leaf value corresponds to the stem 0, we need to combine them to determine the lowest score. Therefore, the lowest score on the test is 01.

To find the highest score on the test, we look at the largest leaf value in the diagram, which is 9. Since the largest leaf value corresponds to the stem 9, the highest score on the test is 99.

The mean score on the test is calculated by adding up all the scores and dividing by the total number of students. Let's calculate it:

Mean score = (6 + 7 + 7 + 0 + 0 + 0 + 0 + 0 + 9 + 9 + 9 + 3 + 4) / 40

Mean score = 63 / 40

Mean score ≈ 1.575

The midrange of test scores is calculated by adding the lowest and highest scores and dividing by 2. Let's calculate it:

Midrange = (01 + 99) / 2

Midrange = 100 / 2

Midrange = 50

Therefore, the mean score on the test is approximately 1.575, and the midrange of test scores is 50.

Range describes the y-values of a graph.

Range

Range is the y-values that a graph covers. Remember that the y-values are found on the vertical axis. If the graph is not continuous, then the values between the points are not included in the range. Similar to the range, the domain of a graph is the x-values that a graph covers. If there is a coordinate point with a y-value, then that y-value should be included in the range.

Finding Range

In order to find the range, we need to find all the unique y-values of the graph. Additionally, the range is given in numerical order. This means starting from the least value and going up to the greatest. The lowest y-value is 1, then 2, and finally 4. Even though there are two points where y = 2, we are only looking for unique values. This means that the range is (1,2,4).
