The perimeter of the cafe is calculated to be equal to 190 feet.

A plane shape is a two dimensional figure and its perimeter is the total distance around its outer boundary. It is the sum of the lengths of all its sides.

By careful observation, the cafe have the following lengths at:

left side = 15 + 7 + 16 = 38ft

right side = 3 + 15 + 28 = 46ft

top side = 40 + 3 + 15 = 58ft

bottom side = 48ft

The perimeter of the cafe = 38ft + 46ft + 58ft + 48ft

The perimeter of the cafe = 190 ft.

Therefore, the perimeter of the cafe is calculated to be equal to 190 feet.

In quadrant III, sin x = -5/13 and cos (2x) = 119/169.

To solve the given problem, we are given that cos(x) = -12/13 and x is in quadrant III. We need to find the value of sin(x) and cos(2x).

Since x is in quadrant III, both sin(x) and cos(x) will be negative. Using the Pythagorean identity sin²(x) + cos²(x) = 1, we can solve for sin(x) as follows:

sin²(x) = 1 - cos²(x)

sin²(x) = 1 - (-12/13)²

sin²(x) = 1 - 144/169

sin²(x) = (169 - 144)/169

sin²(x) = 25/169

Taking the square root of both sides, we get:

sin(x) = ±√(25/169)

sin(x) = ±(5/13)

Since x is in quadrant III where sin(x) is negative, we have:

sin(x) = -5/13

To find cos(2x), we can use the double-angle formula for cosine:

cos(2x) = cos²(x) - sin²(x)

cos(2x) = (-12/13)² - (-5/13)²

cos(2x) = 144/169 - 25/169

cos(2x) = 119/169

Therefore, sin(x) = -5/13 and cos(2x) = 119/169.

the probability that the diameter of a elected bearing is greater than 85 millimeter P(diameter > 85) = P(z > (85-81)/4) = P(z > 1) = 0.1587

The diameter of ball bearings is normally distributed, with a mean of 81 millimeters and a variance of 16.

To calculate the probability that a selected bearing has a diameter greater than 85 millimeters, we first calculate the z-score for 85 millimeters.

We subtract 81 from 85 to get 4, and divide by 4 to get 1 for the z-score.

We the look up the probability for a value of 1 in the z-table, which is 0.1587.

This is the probability that a selected bearing has a diameter greater than 85 millimeters, rounded to four decimal places.

Answer:

i believe the answer is 3^2(-2)^6/ 5^4

Step-by-step explanation:

The best point estimate of the population mean is 6.7. The value for a 95% and 99% confidence interval of approximately (5.87, 7.53) and (5.58, 7.82) respectively and 95% confidence interval is smaller than the 99%.

The best point estimate of the population mean is the sample mean, which is 6.7. Since the sample mean is calculated from a random sample, it provides an estimate of the population mean.

To calculate the 95% confidence interval of the mean number of grandchildren, we can use the formula: Confidence Interval = sample mean ± (critical value * standard deviation / sqrt(sample size)). The critical value for a 95% confidence level is approximately 1.96.

Plugging in the values: Confidence Interval = 6.7 ± (1.96 * 4 / sqrt(50)). Calculating this, we get a confidence interval of approximately (5.87, 7.53).

Similarly, to calculate the 99% confidence interval, we use the critical value of approximately 2.58 for a 99% confidence level. Plugging in the values: Confidence Interval = 6.7 ± (2.58 * 4 / sqrt(50)). Calculating this, we get a confidence interval of approximately (5.58, 7.82).

The 95% confidence interval is smaller than the 99% confidence interval. This is because higher confidence levels require wider intervals to capture a larger range of potential population means. The 99% confidence interval is wider because it allows for a greater margin of error, providing a higher level of confidence but at the cost of increased uncertainty. Conversely, the 95% confidence interval is narrower as it aims to provide a more precise estimate of the population mean with a slightly lower level of confidence. Therefore, the 95% confidence interval is smaller than the 99% confidence interval.

The total number of chocolate chips in the cookies is 1000. All the cookies, except one, have the same number of chips, while the remaining cookie has one more chip than the others. The number of cookies in the jar is between one dozen (12 cookies) and three dozen (36 cookies).

To find the sum of the number of cookies in the jar and the number of chips in the cookie with the extra chocolate chip, we can follow these steps:

1. Let's assume the number of cookies in the jar is "x". Since the number of cookies is between one dozen and three dozen, we have the inequality: 12 ≤ x ≤ 36.

2. Since all the cookies, except one, have the same number of chips, we can divide the total number of chocolate chips by the number of cookies minus one. This gives us the number of chips in each cookie (excluding the one with the extra chip). So, the number of chips in each cookie is 1000 ÷ (x - 1).

3. The cookie with the extra chip has one more chip than the others. Therefore, the number of chips in the cookie with the extra chip is 1000 ÷ (x - 1) + 1.

4. To find the sum of the number of cookies in the jar and the number of chips in the cookie with the extra chocolate chip, we add the number of cookies (x) and the number of chips in the extra chip cookie (1000 ÷ (x - 1) + 1).

Remember that the number of cookies in the jar is between one dozen and three dozen, so the sum will vary depending on the number of cookies. You can substitute different values within the given range (12 ≤ x ≤ 36) to find different possible sums.

Step-by-step explanation:

A bag contains 5 red marbles, 6 blue marbles, 3 green marbles, 4 black marbles, and 2 yellow marbles. A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?

A quick lesson on probability:

The probability of an event is: (the number of ways what you want can happen) / (total number of outcomes possible). For example, in a coin flip, there is 1 way to get heads, and 2 possible outcomes. Thus, the possiblity  of flipping a coin and getting heads is:

(1 way to get heads) / (2 possible outcomes) = 1/2

Then, if we were to flip the coin 100 times, we would expect about 1/2 of the times to be heads, so we should expect heads 50 times.  

On to the problem.

There are 3 green marbles and 4 black marbles, so there are 7 ways to draw a green or black marble.

Then, there are 5 + 6 + 3 + 4 + 2 = 20 possible outcomes.

Using the formula to find the probability, substitute the values we just found.

(the number of ways what you want can happen) / (total number of outcomes possible) =

(7 ways to draw a green or black marble) / (20 marbles that can be drawn) = 7/20 chance of getting a green or black marble.

Then, because there is a 7/20 chance of getting what we want, and there are 100 draws, we can say that an we should get green or black

7/20 * 100 = 35 times, or D

Answer:

Step-by-step explanation:

The product of slopes of perpendicular lines is -1

y = 2x − 4  ⇒   m₁ = 2

m₁m₂ = -1

2m₂ = -1

m₂ = -¹/₂

The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is:  y - y₁ = m(x - x₁)

m = -¹/₂

(4, 3)  ⇒  x₁ = 4,  y₁ = 3

So the equation in point-slope form:

                                                  y - 3 = -¹/₂(x - 4)

Therefore:

y - 3 = -¹/₂x + 2

Mae's walking speed is 10 miles per hour. This is calculated by considering the given information.

Let's assume Mae's walking speed is represented by the variable "x" (in miles per hour). According to the given information, her jogging speed would then be "x + 12.5" miles per hour.

To calculate Mae's exercise time, we can use the formula: time = distance / speed.

Mae jogs 27 miles at a speed of "x + 12.5" miles per hour, so her jogging time can be calculated as:

jogging time = 27 / (x + 12.5)

Mae walks an additional 3 miles at a speed of "x" miles per hour, so her walking time can be calculated as:

walking time = 3 / x

The total exercise time is given as 3 hours. Therefore, we can set up the equation:

jogging time + walking time = 3

Substituting the calculated values, we get:

27 / (x + 12.5) + 3 / x = 3

To solve this equation, we can start by multiplying all terms by x(x + 12.5) to eliminate the denominators:

27x + 27 * 12.5 + 3(x + 12.5) = 3x(x + 12.5)

Simplifying the equation:

\(27x + 337.5 + 3x + 37.5 = 3x^2 + 37.5x\)

Combining like terms:

\(30x + 375 = 3x^2 + 37.5x\)

Rearranging the terms to set the equation equal to zero:

\(3x^2 + 7.5x - 375 = 0\)

To solve this quadratic equation, we can use the quadratic formula:

x = (-b ± √(\(b^2\) - 4ac)) / (2a)

In this case, a = 3, b = 7.5, and c = -375. Substituting these values into the quadratic formula:

x = (-7.5 ± √(\(7.5^2\) - 4 * 3 * -375)) / (2 * 3)

x = (-7.5 ± √(56.25 + 4500)) / 6

x = (-7.5 ± √(4556.25)) / 6

Calculating the square root:

x = (-7.5 ± 67.5) / 6

Simplifying further:

x = (60 / 6) or x = (-75 / 6)

Since Mae's walking speed cannot be negative, the solution is x = 10.

Therefore, Mae's walking speed is 10 miles per hour.
