Answer:

length of the pan is 10 inches

Step-by-step explanation:

Volume = length x width x height

V = lwh

l = (V) / (wh) = (150 in³) / (7.5 in)(2 in) = 10 in

The probability are given as follows:

15) P (point is on N.Q.) = 6 / 13

16) P (point is not on Q.R.) = 10 / 13

17) P (point is on N.Q. or RS) = 10/13

18) P  = 1/54

15)

To find the probability that the point is on line segment N.Q., we need to divide the length of N.Q. by the total length of the line segment NS. The length of NS is the sum of the lengths of N.Q., Q.R., and RS, which is 12 + 6 + 8 = 26. Therefore, the probability that the point is on line segment N.Q. is:

P(point is on N.Q.) = length of N.Q. / length of NS = 12 / 26 = 6 / 13

16)

To find the probability that the point is not on line segment Q.R., we need to subtract the length of Q.R. from the length of NS and divide by the length of NS. The length of Q.R. is 6, so the length of NS without Q.R is 12 + 8 = 20. Therefore, the probability that the point is not on line segment Q.R. is:

P (point is not on Q.R.) = (length of NS without Q.R.) / length of NS = 20 / 26 = 10 / 13

17)

To find the probability that the point is on line segment N.Q. or RS, we can add the probabilities of the point being on N.Q. and the point being on RS. We already calculated that the probability of the point being on N.Q. is 6/13. To find the probability of the point being on RS, we can use the same method as in part (15). The length of RS is 8, so the probability that the point is on RS is:

P(point is on RS) = length of RS / length of NS = 8 / 26 = 4 / 13

Therefore, the probability that the point is on N.Q. or RS is:

P(point is on N.Q. or RS) = P (point is on N.Q.) + P(point is on RS) = 6/13 + 4/13

= 10/13

18)

The bus stops at the lot every 18 minutes and stays for 2 minutes, so the shuttle is at the lot for a total of 20 minutes out of every 18 * 60 = 1080 minutes. Therefore, the probability that the bus is at the lot when you arrive is:

P (bus is at the lot) = time the shuttle is at the lot / total time = 20 / 1080

= 1/54

Note that this assumes that you arrive at a random time within the 1080 minutes and that the bus is equally likely to be at the lot at any time during its 20-minute stay.

Also B = 2π/T

Now from the graph, T = π/2

So,  we substitute for B in the equation for B, thus

B = 2π/T

= 2π/(π/2)

Answer:

The end behavior of the given radical function f(x) = 4√(x-6) as x approaches positive infinity is option A: As x approaches positive infinity, f(x) approaches positive infinity.

Step-by-step explanation:

This is because as x approaches positive infinity, the value inside the square root (x-6) also approaches positive infinity. As the square root of a positive number is also positive, f(x) approaches positive infinity.

We can also see this by using the concept of limits. As x approaches positive infinity, the limit of f(x) can be evaluated as:

lim f(x) = lim 4√(x-6)

x→∞ x→∞

= 4√(lim(x-6))

x→∞

Since the limit of (x-6) as x approaches positive infinity is positive infinity, we have:

lim f(x) = 4√(∞) = ∞

x→∞

Therefore, as x approaches positive infinity, f(x) approaches positive infinity.

The area of the smaller triangle is 12 square units

If the scale factor between two similar triangles is 2/3

It means that every length of the smaller triangle is 2/3 the length of the corresponding side of the larger triangle.

So, the ratio of their areas is the square of the scale factor

This is represented as

(area of smaller triangle) / (area of larger triangle) = (2/3)^2 = 4/9

We are given that the area of the larger triangle is 27

So, we have

Area of smaller triangle/27 = 4/9

Multiplying both sides by 27, we get:

Area of smaller triangle = (4/9) * 27

Evaluate

Area of smaller triangle = 12

Hence, the area of the smaller triangle is 12.

Answer:

Mary Ellen is MOST LIKELY going to use shears to cut the linen.

According to the given information, the slope of line AB is  [tex]\frac{2}{3}[/tex].

What is the slope?

The slope of a line is a measure of how steep the line is. It tells us how much the y-coordinate of the line changes for each unit of change in the x-coordinate.

To visualize a slope, imagine a line on a coordinate plane. If the line is steep, it means that for each unit of increase in the x-coordinate, the y-coordinate changes by a larger amount. Conversely, if the line is less steep, it means that for each unit of increase in the x-coordinate, the y-coordinate changes by a smaller amount.

To find the slope of a line that passes through two given points, we use the slope formula:

[tex]slope = \frac{(change in y) }{(change in x)}[/tex]

In this case, we have points A(0, -2) and B(3, 0).

So the change in y is 0 - (-2) = 2, and the change in x is 3 - 0 = 3.

Therefore, the slope of line AB is:

[tex]slope = \frac{(change in y) }{(change in x)} = \frac{2}{3}[/tex]

Since the slope is positive, we know that the line slants upwards as we move from left to right on the coordinate plane.

Answer:

the net asset value of Rae's antivirus software two years after her purchase was $570.84, which is not one of the given options.

Step-by-step explanation:

The software was used for 12 years, and Rae is selling it now. So, it has been used for 12 - 2 = 10 years.

Annual depreciation = (cost - salvage value) / useful life = (985 - 0) / 12 = 82.08

Depreciation for 10 years = 82.08 x 10 = $820.80

Net asset value after 2 years = cost - accumulated depreciation = 985 - 82.08 x 2 = $820.84

However, Rae is selling the software for $250, so her net asset value is $820.84 - $250 = $570.84

Therefore, the net asset value of Rae's antivirus software two years after her purchase was $570.84, which is not one of the given options.

The most typical way to display data in a graph is to demonstrate how two additional factors relate to one another. Digital and hand-drawn sketches are both acceptable. From the beginning position, move two or more pieces to the correct and three pieces up. The reference system must display the numerals for positions 2, 3, and 4. In your points, be very clear. The pinkish haze with the letter P stands in for the number 2.3.

Here,

We must compute several numbers in order to determine the Pearson correlation coefficient r for the information provided in the table.

Before anything else, we figure out the average and standard deviation of the amount of TV airings (x) and car sales (y):

mean(x) = (40 + 30 + 20 + 50 + 10) / 5 = 30

mean(y) = (30 + 20 + 10 + 40 + 20) / 5 = 24

These mean numbers allow us to determine the standard deviation:

=> SX = √ (( (40-30)² + (30-30)² + (20-30)² + (50-30)² + (10-30)²) / 4)

≈> 15.81

=> SY = √(( (30-24)²+ (20-24)² + (10-24)² + (40-24)² + (20-24)²) / 4)

≈> 8.16

Next, we determine x and y's covariance:

=> cov(x,y) =

=> [(40-30)(30-24) + (30-30)(20-24) + (20-30)(10-24) + (50-30)(40-24) + (10-30)(20-24)] / 4

≈>  125

Last but not least, we can figure out the Pearson association coefficient:

0.975 r = cov(x,y) / (s x * s y)

Answer:

the probability that a child is excluded from all rides is 0.5000 (rounded to three decimal places).

Step-by-step explanation:

We can use the standard normal distribution to solve this problem. We first need to standardize the height requirements using the population mean and standard deviation.

a) To find the probability that a child can go on all rides, we need to find the probability of getting a height of at least 54 inches.

z-score = (54 - 53) / 4 = 0.25

Using a standard normal table or calculator, we find that the probability of getting a z-score of 0.25 or greater is 0.4013.

Therefore, the probability that a child can go on all rides is 0.4013 (rounded to three decimal places).

b) To find the probability that a child can participate in only mild and moderate rides, we need to find the probability of getting a height between 42 inches and 48 inches.

First, we find the z-scores for each height requirement:

z-score for 42 inches = (42 - 53) / 4 = -2.75

z-score for 48 inches = (48 - 53) / 4 = -1.25

Using a standard normal table or calculator, we find that the probability of getting a z-score between -2.75 and -1.25 is 0.2375.

Therefore, the probability that a child can participate in only mild and moderate rides is 0.2375 (rounded to three decimal places).

c) To find the probability that a child can only go on mild rides, we need to find the probability of getting a height of less than 42 inches.

z-score = (42 - 53) / 4 = -2.75

Using a standard normal table or calculator, we find that the probability of getting a z-score of -2.75 or less is 0.0030.

Therefore, the probability that a child can only go on mild rides is 0.0030 (rounded to three decimal places).

d) To find the probability that a child is excluded from all rides, we need to find the probability of getting a height less than 42 inches or greater than 54 inches.

First, we find the z-scores for each height requirement:

z-score for 42 inches = (42 - 53) / 4 = -2.75

z-score for 54 inches = (54 - 53) / 4 = 0.25

Using a standard normal table or calculator, we find that the probability of getting a z-score of less than -2.75 or greater than 0.25 is 0.0987 + 0.4013 = 0.5000.

Therefore, the probability that a child is excluded from all rides is 0.5000 (rounded to three decimal places).

To stretch the graph horizontally by a factor of 3, we need to multiply the x-coefficient by 1/3. Similarly, to stretch the graph vertically by a factor of 7, we need to multiply the y-coefficient by 1/7. Therefore:

(5/9)x² + (8/3)x + 4y² - 4y = 70

Vertically stretched graph: 5x² + 8x + 4(1/7y)² - 4(1/7)y = 70
