Answer:

48%

Step-by-step explanation:

48/100 = 48%

Edit: the awnser is 64% because 48/75 = 64%

The probability that a customer ordered a medium given that he or she ordered a hot drink is,

⇒ 48%

What is mean by Probability?

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

At a coffee shop, the first 100 customers orders were as given.

Now,

Total customer = 100

Order hot median coffee = 48

Thus, The probability that a customer ordered a medium given that he or she ordered a hot drink is,

⇒ 48 / 100

⇒ 0.48

⇒ 48%

Thus, The probability that a customer ordered a medium given that he or she ordered a hot drink is,

⇒ 48%

Answer:

Step-by-step explanation:

Volume of the cylinder = volume of the outer cylinder - volume of the inner cylinder

volume of the inner cylinder = πr2h

r = 1

h = 6

Volume = 18.85

Volume of outer cylinder =  πr2h

r = 6/2 = 3

h = 6

volume = 169.65

Volume of the desired cylinder = 169.65 - 18.85 = 150.8

Answer:

There is sufficient evidence to conclude that six inches spacing has a higher mean failure pressure than 8 inches

Reject [tex]H_0\ at\ 5%[/tex] level of significance

Step-by-step explanation:

From the question we are told that:

Sample size 1 [tex]n_1=15[/tex]

Spacing 1 [tex]s_1=8[/tex]

Mean 1 [tex]\=x_1=8.48[/tex]

Standard deviation 1 [tex]\sigma_1=0.96 kPa[/tex]

Sample size 2 [tex]n_2=16[/tex]

Spacing 2 [tex]s_2=6[/tex]

Mean 1 [tex]\=x_1=9.93[/tex]

Standard deviation 1[tex]\sigma_1=1.02 kPa[/tex]

Generally the hypothesis is mathematically given as

Null [tex]H_0:\mu_1-\mu_2[/tex]

Alternative [tex]H_a:\mu_1\mu_2[/tex]

Generally the equation for pooled estimate is mathematically given by

  [tex]S=\sqrt{\frac{(n_1-1)\sigma_1^2+(n_2-1)\sigma_2^2}{n_1+n_2-2} }[/tex]

Therefore

  [tex]S=\sqrt{\frac{(15-1)0.96^2+(16-1)1.02^2}{15+15-2} }[/tex]

 [tex]S=0.9905[/tex]

Generally the equation for test statistics is mathematically given by

 [tex]t=\frac{\=x_1+\=x_2}{S\sqrt{\frac{1}{n _1}+\frac{1}{n_2}}}[/tex]

 [tex]t=\frac{\=8.48-9.93}{0.9905\sqrt{\frac{1}{15}+\frac{1}{15}}}[/tex]

 [tex]t=-4.00091[/tex]

Therefore From table

 [tex]P value=P(t_{15+15-2}=4.00091)[/tex]

 [tex]P value=0.00041918[/tex]

 [tex]P<0.0005[/tex]

Therefore

There is sufficient evidence to conclude that six inches spacing has a higher mean failure pressure than 8 inches

The nth term is 35+ 7(n-1) or can be written 28 + 7n

Step-by-step explanation:

This is an arithmetic sequence, where each term equals the previous term, with a constant value added.

T1 = 35

T2 = 42 = T1 + 7 = 35 + 7

T3 = 49 = T2+ 7 = 35 + 7 + 7 = 35 + 2x7

The nth term is equal to 35 + 7X(n-1)

Answer:

y = 7x

Step-by-step explanation:

Complete question:

Find an equation for the line with the given properties. Parallel to the line 7x - y = -7; containing the point (0,0)

The equation of a line in point-slope form is expressed as;

y - y0 = m(x-x0)

(x0, y0) = (0,0)

Given the equation of the line as 7x - y = -7;

Rewrite and get the slope

-y = -7x - 7

y = 7x+7

Get the slope

mx = 7x

m = 7

Substitute into the equation

y - 0 = 7(x - 0)

y = 7x

Hence the required equation is y = 7x

Explanation:

The box plot, aka "box-and-whisker plot", visually represents five things. These things are:

This list of five items is known as the five number summary.

The min is the tip of the left most whisker, assuming there aren't any small outliers. The max is the opposite side, being the tip of the right most whisker (assuming no large outliers). If there are any outliers, then they'll be shown as "island" dots on their own separated from the main box plot. The left and right edges of the box are Q1 and Q3 respectively. The median is the vertical line inside the box. The vertical line does not have to be at the midpoint of the left and right edges of the box. It simply needs to be somewhere in the box.

--------

Since the box plot lets us know the min and max, we can compute the range because

range = max - min

and we can also calculate the interquartile range (IQR) because

IQR = Q3 - Q1

--------

So to summarize so far, the five number summary is visually represented as the box plot. The range and IQR can be computed using items from the five number summary.

We cannot compute the mean because we would need the actual data set of values, rather than the summary data. The same goes for the mean absolute deviation (MAD) and the mode. Since your teacher is looking for things that cannot be determined from a box plot, we'll go for answers B, C and E.

In other words, we rule out choices A, D, and F because we can compute or determine those values from a box plot.

12. Each section of the line on each side is identical (shown by the marks through each line)

This means both those angles are also the same.

6x + 1 = 9x-23

Add 23 to both sides

6x + 24 = 9x

Subtract 6x from both sides

24 = 3x

Divide both sides by 3

X = 8

13. Both angles when added together need to equal 180

5x-24 + 8x +9 = 180

Combine like terms

13x -15 = 180

Add 15 to both sides

13x = 195

Divide both sides by 13

X = 15

Answer:

0.6603 = 66.03% probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Sent by ABC Speedy Delivery Service.

Event B: Arrived on time.

The probability that any given parcel will be sent by the ABC Speedy Delivery Service is 0.71.

This means that [tex]P(A) = 0.71[/tex]

The probability that the parcel will arrive on time given the ABC Speedy Delivery Company was used is 0.93.

This means that [tex]P(B|A) = 0.93[/tex]

Find the probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.

This is [tex]P(A \cap B)[/tex]. So

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

[tex]P(A \cap B) = P(B|A)*P(A) = 0.93*0.71 = 0.6603[/tex]

0.6603 = 66.03% probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.

===========================================================

Explanation:

We'll use the remainder theorem.

This theorem says that if you divide p(x) over (x-k), then the remainder is p(k).

We have p(x) = x^3 + 3x^2 - 16x - 48 and the denominator is one of the four choices A through D.

Let's go through each of them until we find the answer.

-----------------

For choice A, we have x+2 which is the same as x-(-2). It matches with x-k to show that k = -2.

Plug k = -2 into p(x) to get

p(x) = x^3 + 3x^2 - 16x - 48

p(-2) = (-2)^3 + 3(-2)^2 - 16(-2) - 48

p(-2) = -12

The remainder is -12, which is not 0 like we're after. We can cross A off the list.

-----------------

We'll follow the same ideas for choices B through D

For choice B, we plug in k = 4 because x-4 matches with x-k to show that k = 4.

p(x) = x^3 + 3x^2 - 16x - 48

p(4) = (4)^3 + 3(4)^2 - 16(4) - 48

p(4) = 0

We end up with a remainder of 0, so we can stop here. Dividing (x^3+3x^2-16x-48) all over (x-4) leads to some quotient and a remainder of 0.

Put another way: (x-4) is a factor of x^3+3x^2-16x-48
