To find

Let the purchase value be P,

ATQ,

P -3 x 0.1P = Rs 43,740

P-0.3P = Rs 43,740

0.7P = Rs 43,740

P = Rs 43,740/0.7

P = Rs 62,486 (approx)

Hence, the purchase value of the machine would be Rs 62,486

The Emily soccer team has the higher ratio of wins to losses.

Ratio is defined as the relationship between two quantities where it tells how much one quantity is contained in the other.

The ratio of a and b is denoted as a : b.

Given that,

Ratio of win to loss of Emily soccer team = 9 : 12

Ratio of win to loss of Grant soccer team = 10 : 15

9 : 12 = 9 / 12 = (9 × 5) / (12 × 5) = 45 / 60

10 : 15 = 10 / 15 = (10 × 4) / (15 × 4) = 40 / 60

If 60 games are losses, then 45 games are wins for Emily soccer team.

If 60 games are losses, then 40 games are wins for Grant soccer team.

Higher ratio is for Emily soccer team.

Hence higher ratio of wins to losses is for Emily soccer team.

Answer:

2(5) + 2√(3^2 + 7^2) = 10 + 2√58 = 25.2

B is the correct answer.

Given:

The data table of the survey of pets is given.

Required:

Find results, are being a picky eater and being a dog with independent or dependent events.

Explanation:

The total number of pets = 50

The number of picky eater pets = 17

The probability of an event is given by the formula:

The probability of randomly choosing a picky eater is:

The total number of dogs = 25

The number of picky eater cats = 6

The probability of a picky eater dog

We notice that both results are different. The fact that the pet selected is a dog changes the probability of P(picky).

This means the events are dependent.

Final Answer:

Option B is the correct answer.

Explanation:

**Slope = rise/run**

By counting the distance between the points, from (0,3) to (1,1) , it went down 2 units and right by 1 unit

Answer:

m= -2

Step-by-step explanation:

Pick two points and subtract the y coordinates, then subtract the x coordinates, (0,3) and (1,1)  or (1,1) and (2,-1)

\(m = \frac{y_{2_ } - y_{1} }{x_{2} -x_{1} } = \frac{1-3}{1-0} = \frac{-2}{1} = -2\)      \(\frac{-1-1}{2-1} = \frac{-2}{1} = -2\)

Answer:  \(y=\frac{13}{2} x+3\)

Step-by-step explanation:

Remember the point-slope equation which is \(y-y_{1} = m(x-x_{1} )\)  where\((x_{1} , y_{1} )\) is your point and \(m\) is your slope.

Given that we substitute what you have:

\(y-(-10) =\frac{13}{2} (x - (-2))\)

Minus and minus give us positive:

\(y+10 =\frac{13}{2} (x +2)\)

Multiply slope into the parenthesis:

\(y+10= \frac{13}{2}x + \frac{13}{2}*2\\\)

Calculate it:

\(y+10= \frac{13}{2}x +13\)

Isolate the \(y\) by subtracting 10 from both sides:

\(y=\frac{13}{2} x + 13 -10\)

Your final equation is:

\(y=\frac{13}{2} x +3\)

Hope this makes sense!

Answer: 1.977

Step-by-step explanation:

Answer:

1.977

Step-by-step explanation:

Using z-scores, we have that due to the higher z-score, the water bottling facility increased their efficiency more during that hour.

In a normal distribution with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

In this problem, the facility with the higher z-score increased their efficiency more during that hour.

For the water bottling facility, we have that \(\mu = 33.5, \sigma = 1.92, X = 34.9\), hence:

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{34.9 - 33.5}{1.92}\)

\(Z = 0.73\)

For the cola bottling facility, we have that \(\mu = 26.2, \sigma = 1.42, X = 26.8\), hence:

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{26.8 - 26.2}{1.42}\)

\(Z = 0.42\)

Due to the higher z-score, the water bottling facility increased their efficiency more during that hour.

They have the same x-intercept and the same end behavior as x approaches ∞. D. They have the same y-intercept and the same end behavior as x approaches ∞.

answer: the range is 41.

to find the range of this data set, we first need to find the minimum and maximum values - which are 59 and 100.

then we subtract the minimum from the maximum.

59 - 100 = 41.

It should be noted that the number of sample size based on the information will be 300.

In order to calculate the sample size, we can use the following formula:

n = z² * p * (1-p) / E²

n = 1.96² * 0.5 * (1-0.5) / 0.05²

= 300

Answer:

To find the volume of the shipping box in cubic feet, we need to convert the dimensions from inches to feet and then calculate the volume.

Given:

Length = 36 inches

Width = 24 inches

Height = 18 inches

Converting the dimensions to feet:

Length = 36 inches / 12 inches/foot = 3 feet

Width = 24 inches / 12 inches/foot = 2 feet

Height = 18 inches / 12 inches/foot = 1.5 feet

Now, we can calculate the volume of the box by multiplying the length, width, and height:

Volume = Length * Width * Height

Volume = 3 feet * 2 feet * 1.5 feet

Volume = 9 cubic feet

Therefore, the shipping box can hold 9 cubic feet.

Step-by-step explanation:

First convert the units because it's asking for the cubic feet but they give us the measurements in inches.

To convert inches to feet we divide the number by 12.

36 ÷  12 = 3

24 ÷  12 = 2

18 ÷ 12 = 1.5

Now to find the volume, we multiply it all together.

3 × 2 × 1.5 = 9

It can hold 9 cubic feet.

There are 2 semi circles.

One that is on left side ( say S1)and the other one at the bottom(say S2) of the figure. Both these semi circles have diameter 30.

perimeter of S1 = (2*pi*15)/2

perimeter of S2 = (2*pi*15)/2

There is another figure which is of a semicricle(say S3). The radius is 30.

Perimeter of S3 = (2*pi*30)/4

Required perimeter

= S2+ S3-S1

= [(15*pi)/2] + [(15*pi)]- [(15*pi)/2]

= (15*pi)
