Answer:

The speed of 65 ​mph is an outlier in the distribution of the​ player's serve​ speeds

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 100 mph

Standard Deviation, σ = 10 mph

Formula:

[tex]z_{score} = \displaystyle\frac{x-\mu}{\sigma}[/tex]

Outlier on basis of z-score:

Calculation of z-score:

[tex]x = 65\Rightarrow z = \dfrac{65-100}{10} = -3.5\\\\x = 110\Rightarrow z = \dfrac{110-100}{10} = 1\\\\x = 120\Rightarrow z = \dfrac{120-100}{10} = 2[/tex]

Thus, the speed of 65 ​mph is an outlier in the distribution of the​ player's serve​ speeds as the corresponding z-score is less than -3.

Step-by-step explanation:

There are 120 different ways to assign 6 weapons to 3 soldiers, each receiving one weapon, calculated using permutations.

Calculating Permutations for Weapons Assignment

To determine how many different ways 3 soldiers can be assigned weapons from a selection of 6, we need to calculate the permutations of 6 objects taken 3 at a time. We use the permutation formula, which is expressed as P(n, k) = n! / (n-k)!, where n is the total number of items, and k is the number of items to choose. In this case, n is 6 (the total number of weapons), and k is 3 (the total number of soldiers).

We calculate the permutations as follows:

6! / (6-3)! = (6  * 5 * 4) / (3 * 2 * 1) = 120 ways.

Therefore, there are 120 different ways to assign the weapons to the soldiers, with each soldier getting one weapon.

3) (-5m/3) + (4x/3)

4) (4x/9) + (8y/9) - (z/3)

5) (-5a/8) + (-3b/8) + (-3c/2)

Step-by-step explanation:

1) 2a-3b divided by 6

(2a-3b)/6 = (2a/6) - (3b)/6 = (a/3) - (b/2)

2) 4m+5n divided by 12

(4m+5n)/12 = (4m/12) + (5n/12) = (m/3) + (5n/12)

3) 5m-4x divided by -3

(5m-4x)/(-3) = (-5m/3) + (4x/3)

4) 4x+8y-3z divided by 9

(4x+8y-3z)/9 = (4x/9) + (8y/9) - (3z/9) = (4x/9) + (8y/9) - (z/3)

5) 5a+3b+12c divided by -8

(5a+3b+12c)/(-8) = (-5a/8) + (-3b/8) + (-12c/8) = (-5a/8) + (-3b/8) + (-3c/2)

Answer:

a = 13

Step-by-step explanation:

The three angles of any triangle MUST add up to 180°.  Thus, 3a + 8a + 37 = 180, and 11a = 180 - 37 = 143.

If 11a = 143, then a = 143/11 = 13

a = 13

Answer:

a = 13

Step-by-step explanation:

8a + 3a + 37° = 180°

11a + 37° = 180°

11a = 180° - 37°

11a = 143°

a = 143/11

a = 13

Find the volume of the candle using the formula for volume of a cylinder:

V = PI x r^2 x h = 3.14 x 3.4^2 x 6 = 217.79 cubic cm. Round to 217.8

Find the volume of the block: V = l x w x h = 15 x 12 x 18 = 3,240 cubic cm.

Now divide the volume of the block by the volume of a candle:

3240 / 217.8 = 14.88

Round to the nearest tenth = 14.9 candles.

Number of cylindrical candles after melting the rectangular block  is 14.9.

" Cylinder is a three dimensional surface formed by two parallel lines and two parallel circular base."

" Volume is the total amount of space occupied by any 3 dimensional body."

Formula used

Volume of a cylinder = π r²h

Volume of a rectangular block = length × width ×height

According to the question,

Height of a cylinder = 6cm

radius of cylinder = 3.4cm

Length of a block = 15cm

width of a block = 12cm

height of a block = 18cm

Volume of a cylinder = [tex]3.14[/tex]× [tex](3.4)^{2}[/tex]×[tex]6[/tex]

                                  =217.8 cubic cm

Volume of rectangular block = [tex]15[/tex] × [tex]12[/tex] × [tex]18[/tex]

                                                 = 3240 cubic cm

Number of candles = Volume of rectangular block / volume of cylinder

                                 = [tex]\frac{3240}{217.8}[/tex]

                                 = 14.88

                                 = 14.9 (nearest tenth)

Hence the Number of cylindrical candles after melting the rectangular block  is 14.9.

Answer:

rate of motorboat: b

rate of current: c

So the rate the boat travels upstream is $b - c$, and the rate it travels downstream is $b + c$

Step-by-step explanation:

d = rt

200 = (b - c)\cdot 5

200 = (b + c)\cdot 4

b - c = 40

b + c = 50

Adding these equations, we get:

2b = 90

b = 45

So

c = 50 - 45 = 5

Therefore the rate of the boat is 45kph, and the rate of the current is 5kph

Hope this helps :)

Final answer:

The boat has a speed of 45 mph in still water, and the current runs at 5 mph. By using the given times and distances for upstream and downstream travel, we can set up equations to solve for the boat's speed and the current's speed.

Explanation:

To find the rate of the boat in still water and the rate of the current, let's denote the boat's speed in still water as b and the speed of the current as c. When the boat goes upstream, its effective speed is b - c, and when it goes downstream, its effective speed is b + c. We can translate this into two equations based on the information given:

(b - c) × 5 hours = 200 miles (upstream)

(b + c) × 4 hours = 200 miles (downstream)

By dividing the distance by the time, we can solve for the effective speeds upstream and downstream.

b - c = 200 miles / 5 hours = 40 mph

b + c = 200 miles / 4 hours = 50 mph

Add these two equations:

2b = 90 mph

b = 45 mph (boat's speed in still water)

Next, subtract the first equation from the second:

2c = 10 mph

c = 5 mph (current's speed)

So, the boat has a speed of 45 mph in still water, and the current has a speed of 5 mph.

Answer: The correct answer is option B: There are between 15 and 20 green pieces in all 5 packages

Step-by-step explanation: The most important factor has been given which is, "Which statement about the candy pieces in the remaining packages is best supported by this information."

The information given is such that, the first package she opened had 4 green pieces and on this basis we can safely assume that all other packages have 4 green pieces as well. The second package had 3 green pieces and this based on this too we can safely assume that all other packages had 3 green pieces. Hence, all 5 packages can either have a total of 4 x 5 green candies which equals a total of 20 green pieces or, all 5 packages can have a total of 3 x 5 green candies which equals a total of 15 green pieces.

So according to Suzi's experiment, there are between 15 and 20 green pieces in all 5 packages.

Answer: [tex]5.05[/tex]

Answer:

  cone volume = cylinder volume times 1/3 the ratio of cone height to cylinder height

Step-by-step explanation:

Let h1 and V1 represent the height and volume of the cylinder, and h2 and V2 the height and volume of the cone.

We are told they have a common base area (B), so ...

  V1 = Bh1   ⇒   B = V1/h1

  V2 = (1/3)Bh2 = (1/3)(V1/h1)h2

The volume of the cone is ...

  V2 = h2/(3h1)×V1

"one-third the ratio of cone height to cylinder height, multiplied by the cylinder volume."
