Answer: A: 0.0031

Step-by-step explanation:

Given : In a study of wait times at an amusement park, the most popular roller coaster has a mean wait time of 17.4 minutes with a standard deviation of 5.2 minutes.

i.e. [tex]\mu=17.4[/tex] and [tex]\sigma=5.2[/tex]

We assume that the wait times are normally distributed.

samples size : n= 30

Let x denotes the sample mean wait time.

Then, the probability that the mean wait time is greater than 20 minutes will be :

[tex]P(x>20)=1-P(x\leq20)\\\\=1-P(\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}\leq\dfrac{20-17.4}{\dfrac{5.2}{\sqrt{30}}})\\\\=1-P(z\leq2.74)\ \ [\because\ z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=1-0.9969\ \ [\text{ By z table}]\\\\=0.0031[/tex]

Hence, the probability that the mean wait time is greater than 20 minutes.= 0.0031

Thus , the correct answer is A: 0.0031 .

Option A

Volume of bed is [tex]2\frac{2}{3}[/tex] cubic inches

Solution:

Given are the dimensions of bed

To find: volume of bed

Since bed is generally of cuboid shape, we can use the volume of cuboid formula

volume of cuboid is given as:

[tex]\text{ volume of cuboid } = l \times w \times h[/tex]

Where, "l" is the length and "w" is the width and "h" is the height of cuboid

From attached figure in question

[tex]l = 2\frac{2}{3} inches = \frac{3 \times 2 + 2}{3} = \frac{8}{3} inches[/tex]

[tex]w = 3 inches[/tex]

[tex]h = \frac{1}{3} inches[/tex]

Substituting the values in formula,

[tex]v = \frac{8}{3} \times 3 \times \frac{1}{3}\\\\v = \frac{8}{3} = 2\frac{2}{3}[/tex]

Therefore volume of bed is [tex]2\frac{2}{3}[/tex] cubic inches

Answer:

40g of chocolate are left.

Step-by-step explanation:

3/5*100=300/5=60

100-60=40

Final answer:

To find the amount of chocolate left, subtract the amount eaten from the original 100g bar.

Explanation:

To find the number of grams of chocolate left, you need to subtract the amount Captain ate from the original 100g bar. Captain ate 3/5 of the bar, so you can calculate the amount eaten by multiplying 3/5 by 100g. This gives you 60g. To find the amount left, you subtract 60g from 100g. The answer is 40g.

Answer:

y-8=-3/2(x+8)

Step-by-step explanation:

y-y1=m(x-x1)

y-8=-3/2(x-(-8))

y-8=-3/2(x+8)

Final answer:

The equation of the line in the point-slope form that passes through (-8, 8) with a slope of -3/2 is y - 8 = (-3/2)(x + 8).

Explanation:

To write an equation in point-slope form for a line that passes through a given point with a known slope, we use the formula y - y1 = m(x - x1), where (x1, y1) is the point the line passes through and m is the slope of the line.

For the line that passes through the point (-8, 8) with a slope of -3/2, we substitute these values into the point-slope form equation:

y - 8 = (-3/2)(x + 8)

This equation represents the specific line asked in the problem.

[tex]\frac{2g+63}{5} \leq  3\\2g+63 \leq 15\\2g \leq 15-63\\2g \leq -48\\g \leq -24[/tex]

Now, lets solve the next inequality with simple algebra. Process shown below:

[tex]13g-34>44\\13g>44+34\\13g>78\\g>6[/tex]

Hence, we can say:

g is less than or equal to -24  AND  g is greater than 6

Answer:

[tex]y=1500\cdot(0.902)^T[/tex]

Step-by-step explanation:

Let T be the number of years since the start of the study and y be the area that the forest covers in [tex]\text{km}^2[/tex].

We have been given that at the beginning of an environmental study a forest cover an area of 1500 [tex]\text{km}^2[/tex]. Since then this area has decreased by 9.8% each year.

We know that an exponential function is in form [tex]y=a\cdot(1-r)^x[/tex], where,

y = Final amount,

a = Initial amount,

r = Decay rate in decimal form,

x = Time.

Let us convert 9.8% into decimal as:

[tex]9.8\%=\frac{9.8}{100}=0.098[/tex]

We have been given that initial value (a) is [tex]1500[/tex].

Upon substituting our given values, we will get:

[tex]y=1500\cdot(1-0.098)^T[/tex]

[tex]y=1500\cdot(0.902)^T[/tex]

Therefore, our required exponential function would be [tex]y=1500\cdot(0.902)^T[/tex].

Answer:

The fraction of trip completed by Andre is  [tex]\frac{31}{24}[/tex] km

Step-by-step explanation:

Given as :

The Total distance between the home to a festival = 1 [tex]\frac{5}{8}[/tex] km

I.e The total distance between the home to a festival =  [tex]\frac{13}{8}[/tex] km

The distance cover by Andre before taking rest =  [tex]\frac{1}{3}[/tex] km

Let The fraction of trip completed by Andre = x km

So, According to question

The fraction of trip completed by Andre = The Total distance between the home to a festival - The distance cover by Andre before taking rest

or, x =  [tex]\frac{13}{8}[/tex] km - [tex]\frac{1}{3}[/tex] km

or, x =  [tex]\frac{39 - 8}{24}[/tex] km

∴ x = [tex]\frac{31}{24}[/tex] km

Or, The fraction of trip completed by Andre = x = [tex]\frac{31}{24}[/tex] km

Hence , The fraction of trip completed by Andre is  [tex]\frac{31}{24}[/tex] km Answer

Answer:

[tex]\frac{4}{15}[/tex]

Step-by-step explanation:

We know that the total distance is

[tex]1\frac{5}{8}km[/tex] which is standard fraction would be [tex]\frac{13}{8}km[/tex].

So, Andre walks [tex]\frac{1}{3}km[/tex], that means he needs to walk the following distance to get to the festival

[tex]\frac{13}{8}-\frac{1}{3}=\frac{39-8}{24}=\frac{31}{24}km[/tex]

Now, to find the fraction of the tripe that represents the distance he already completed, we have to divide

[tex]\frac{1}{3} \div \frac{13}{8}=\frac{1}{3} \times \frac{8}{13}=\frac{8}{30}=\frac{4}{15}[/tex]

Therefore, we completed a [tex]\frac{4}{15}[/tex] part of the total distance.

Step-by-step explanation:

21 percent of 3,876 is 813.96$, and 17 percent of 4552 is 773.67$. 813.96>773.67

21% of $3,876 is $813.96, while 17% of $4,552 is $773.84. Therefore, 21% of $3,876 inequality sign is greater than 17% of $4,552.

Choosing between 21% of $3,876 or 17% of $4,552 involves calculating each percentage of the given amounts to compare which is greater. To do this:

Calculate 21% of $3,876: 0.21 × 3876 = $813.96.

Calculate 17% of $4,552: 0.17 × 4552 = $773.84.

Comparing these two amounts using an inequality sign, we see that $813.96 is greater than $773.84. So, you would rather have 21% of $3,876 than 17% of $4,552.

The inequality would be written as:

21% of $3,876 > 17% of $4,552

Answer:

(1,12) and (2,12).

(- 5,1) and (- 5, 2).

Step-by-step explanation:

y = 12 is a line that is parallel to the x-axis and at a constant distance of 12 units above the x-axis. Therefore, the points on the line will have any x-coordinate but have a constant y-coordinate i.e. 12.

Therefore, the two points on the line y = 12 can be (1,12) and (2,12).  

x = - 5 is a line that is parallel to the y-axis and at a constant distance of 5 units left of the y-axis. Therefore, the points on the line will have any y-coordinate but have a constant x-coordinate i.e. - 5.

Therefore, the two points on the line x = - 5 can be (- 5,1) and (- 5, 2).  (Answer)

Answer:

The coordinates of the mid-point are :

[tex](\frac{1}{2}, \frac{5}{2})[/tex]

Step-by-step explanation:

We know that, the coordinates of the mid-point (x, y) of a line segment joining the points (x₁, y₁) and (x₂, y₂) is given by

[tex](x, y) = (\frac{x_{1} +x_{2} }{2},\frac{y_{1}+y_{2} }{2} )[/tex]

Now, we have the given points as (3, 5) and (-2, 0).

By using the above formula, coordinates of the mid-point (x, y) of the line-segment joining the points (3, 5) and (-2, 0) is given by,

[tex]x = \frac{3+(-2)}{2} = \frac{3-2}{2} = \frac{1}{2}[/tex]

[tex]y = \frac{5+0}{2} = \frac{5}{2}[/tex]

∴ coordinates of the mid-point of the line-segment joining the points (3,5) and (-2,0) is [tex](\frac{1}{2}, \frac{5}{2})[/tex].
