Answer:

Step-by-step explanation:

Correct choice is D

Answer:

D

Step-by-step explanation:

Given

- (x + 1)² - 4 = 0 ( add 4 to both sides )

- (x + 1)² = 4 ( multiply both sides by - 1 )

(x + 1)² = - 4 ( take the square root of both sides )

x + 1 = ± [tex]\sqrt{-4}[/tex] = ± 2i ( subtract 1 from both sides )

x = - 1 ± 2i , then

x = - 1 + 2i, x = - 1 - 2i → D

Answer:

2/5.

Step-by-step explanation:

To find the denominator, you add all of the times the experiment has been done.

6 + 9 = 15.

Then, since they're asking about purple shirts, you put that as the numerator.

Making it 6/15.

To simplify, divide both sides by 3, making it 2/5 simplified.

The solution is, 2/5 is the experimental probability that the next shirt sold will be purple.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

To find the denominator, you add all of the times the experiment has been done.

[tex] = \frac{60 - 96}{ - 12 - ( - 20)} \\ \\ = \frac{ - 36}{ - 12 + 20} \\ \\ = \frac{ - 36}{ 8} \\ \\ = - \frac{9}{2} [/tex]

Answer:

[tex]AB = 11.3[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Length AB

To do this, we make use of sine law which is represented as:

[tex]\frac{a}{\sin(a)} = \frac{b}{\sin(b)} = \frac{c}{\sin(c)}[/tex]

So, we have:

[tex]\frac{15}{\sin(70)} = \frac{AB}{\sin(45)}[/tex]

Make AB the subject

[tex]AB = \frac{15}{\sin(70)} * \sin(45)[/tex]

[tex]AB = \frac{15}{0.9397} *0.7071[/tex]

[tex]AB = 11.3[/tex]

Answer:D.CENTROID

Step-by-step explanation: THE ONLY CORRECT ANSWER IS CENTROID

Answer:

a. See below for the Frequency and Relative frequency Table.

b. Pitcher (P) is the position provides the most Hall of Famers.

c. 3rd base (3) is the position that provides the fewest Hall of Famers.

d. R is the outfield position that provides the most Hall of Famers.

e. Th number of Hall of Famers of Infielders which is 16 is less than the 18 Hall of Famers of those of outfielders.

Step-by-step explanation:

Note: This question not complete. The complete question is therefore provided before answering the question as follows:

Data for a sample of 55 members of the Baseball Hall of Fame in Cooperstown, New York, are shown here. Each observation indicates the primary position played by the Hall of Famers: pitcher (P), catcher (H), 1st base (1), 2nd base (2), 3rd base (3), shortstop (S), left field (L), center field (C), and right field (R).

L P C H 2 P R 1 S S 1 L P R P

P P P R C S L R P C C P P R P

2 3 P H L P 1 C P P P S 1 L R

R 1 2 H S 3 H 2 L P

a. Use frequency and relative frequency distributions to summarize the data.

b. What position provides the most Hall of Famers?

c. What position provides the fewest Hall of Famers?

d. What outfield position (L, C, or R) provides the most Hall of Famers?

e. Compare infielders (1, 2, 3, and S) to outfielders (L, C, and R).

The explanation of the answers is now provided as follows:

a. Use frequency and relative frequency distributions to summarize the data.

The frequency is the number of times a position occurs in the sample, while the relative frequency is calculated as the frequency of each position divided by the sample size multiplied by 100.

Therefore, we have:

Frequency and Relative frequency Table  

Position           Frequency          Relative frequency (%)

P                               17                             30.91%

H                               4                               7.27%

1                                5                               9.09%

2                               4                               7.27%

3                               2                               3.64%

S                               5                               9.09%

L                               6                               10.91%

C                              5                                 9.09%

R                              7                                12.73%

Total                       55                               100%  

b. What position provides the most Hall of Famers?

As it can be seen from the frequency table in part a, Pitcher (P) has the highest frequency which is 17. Therefore, Pitcher (P) is the position provides the most Hall of Famers.

c. What position provides the fewest Hall of Famers?

As it can be seen from the frequency table in part a, 3rd base (3) has the lowest frequency which is 2. Therefore, 3rd base (3) is the position that provides the fewest Hall of Famers.

d. What outfield position (L, C, or R) provides the most Hall of Famers?

As it can be seen from the frequency table in part a, we have:

Frequency of L = 6

Frequency of C = 5

Frequency of R = 7

Since R has the highest frequency which is 7 among the outfield position (L, C, or R), it implies that R is the outfield position that provides the most Hall of Famers.

e. Compare infielders (1, 2, 3, and S) to outfielders (L, C, and R).

Total frequency of infielders = Frequency of 1 + Frequency of 2 + Frequency of 3 + Frequency of S = 5 + 4 + 2 + 5 = 16

Total frequency of outfielders = Frequency of L + Frequency of C + Frequency of R = 6 + 5 + 7 = 18

The calculated total frequencies above imply that number of Hall of Famers of Infielders which is 16 is less than the 18 Hall of Famers of those of outfielders.

Answer:

The point estimate for p is of 0.12.

The 90% confidence interval for p is 0.0862 < p < 0.1538.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

The manager of the dairy section of a large supermarket chose a random sample of 250 egg cartons and found that 30 cartons had at least one broken egg.

This means that [tex]n = 250, \pi = \frac{30}{250} = 0.12[/tex]

The point estimate for p is of 0.12.

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.12 - 1.645\sqrt{\frac{0.12*0.88}{250}} = 0.0862[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.12 + 1.645\sqrt{\frac{0.12*0.88}{250}} = 0.1538[/tex]

The 90% confidence interval for p is 0.0862 < p < 0.1538.

Answer:

a) 24

b) 63

c) 2

d) -2

Step-by-step explanation:

you are supposed to try different numbers, but...

X-9 = 15 add 9 to both sides

X = 24

7x/9 = 49 multiply both sides by 9

7x = 441 divide by 7

x = 63

3(x + 6) = 24  divide both sides by 3

(x + 6) = 8   subtract 6 from both sides

X = 2

11x + 2 = -20 subtract 2 from both sides

11x = -22 divide both sides by 11

X = -2

Answer:

Q1 = 30.25 minutes

Q2 = 42.5 minutes

Q3 = 40 minutes  

Step-by-step explanation:

Given, In Question

Stem | Leaves

2        |  1 3 5 5 5 8

3        |  1 5 6 7 8 9

4        |  2 3 4 6 6 6 8

5        |  2 2 4 5 7 7 8

Q1 = (1/4)*(n+1)th value

Q2 = (1/2)*(n+1)th value

Q3 = (3/4)*(n+1)th value

where n is the total number of co-workers 26.

             Q1 = 6.75th value

we need to count the leaves in the plot starting from the first one until we reach the 6.75th value. So, by counting, we conclude that the 6.75th value lies between the 6th and 7th value i.e. 28 and 31.

Q1 = 28 + (31-28)*0.75

    = 28 + 2.25

Q1 = 30.25 minutes

                       = 13.5th value.

From the plot, we find that the 13.5th value lies in the middle of the 13th and 14th values i.e. 42 and 43. So,

Q2 = (42+43)/2

     = 85/2  

Q2 = 42.5 minutes

                      = 20.25th value

From the plot. we find that the 20.25th value lies somewhere between the 20th and 21st value i.e. 52 and 52. So,

Q3 = 40 + (52-52)*0.25

    = 40 + 0

Q3 = 40 minutes

Answer:

GHC757.317

GHC181.756

Step-by-step explanation:

Given that :

Discount on sale = 18%

Sale price at 18% discount = 828

828 = 100% - 18%

828 = 82%

The cost at 100% can be represented as :

828 = 0.82

x = 1

Cross multiply :

828 = 0.82x

x = 828 / 0.82

x = 1009.7560

The price 1009.7560 includes a marked gain of 25% ; Hence, cost price of the article is :

(100 - 25)% * 1009.7560

0.75 * 1009.7560

= GHC757.317

Discount allowed :

1009.7560 - 828

= GHC181.756

Where's the picture

Step-by-step explanation:

The picture...

Answer:

151.25cm

Step-by-step explanation:

First split the the shape into two, a rectangle and a semicircle.

Let's begin with the rectangle. The formula for the area of a rectangle is

A = l × w

A = 16 × 7

A = 112

Now we move onto the semicircle. We know that the length of the long side of the rectangle is 16. Because of the markings, we know that the missing portion of the 6cm line is 16 as well. That means that we would do 16 - 6 to find that small missing length. It gives us 10cm which will act as the diameter for the semicircle.

The formula for the area of a semicircle is

A = [tex]\frac{\pi r^{2} }{2}[/tex]          (fill in what you know)

A = [tex]\frac{3.14 (5^{2} )}{2}[/tex]     (The radius is half the diameter. So 10 ÷ 2 = 5)

A = [tex]\frac{3.14(25)}{2}[/tex]     (Solve what's in the parentheses first)

A = [tex]\frac{78.5}{2}[/tex]          (multiply pi and 25)

A = 39.25

Now all we have to do is add the two areas to get the combined area of the whole.

A = 112 + 39.25

A = 151.25

Additional comment

Here, the function simplifies to ...

  f(x) = (2x)(x -1)/(x -1) = 2x

The simplified function can be evaluated directly at the limit value of x, with no approximation needed.

  i = √-1, so i^2 = -1. Otherwise the product is identical to what you would get if "i" were a variable.

Answer:

Try 250 = 70x + 50, or y = 70x + 50.

Step-by-step explanation:

He made 250 total. The variable is how many cars he washes. The y-intercept is 50. Therefore, either 250 = 70x + 50, or y = 70x + 50.

Answer:

250 = 70x + 50

Step-by-step explanation:

this is the equation if you are looking for the profit

Ex.

You washed 2 cars

250 = 70 (2) + 50

250 = 190

-190 -190

60

Step-by-step explanation:

so if in 1994 it was = 1,256

1995 =  1256 +  x  = 1,381     {x is 125}

1996 =  1381  +  x  = 1,519     {x is 138}

2007 = it is eleven years from 1996 to 2007 so take the average of the both digits which we will find through adding both the x quantities and dividing it with 2 the answer is 131.5. back to 2007, so multiply 11 with 131.5 which is 1,446.5. now add 1,446.5 to 1519

and the answer is 2,965.5.

Answer:

68 × y

Step-by-step explanation:

68y = 68 × y

Answer:

Step-by-step explanation:The new line will be parallel to the line represented by y =2x +2

The equation y = 2x + 2 is written in slope- intercept form (i.e. y=mx + b) where m represents the slope.  So the slope of this line is 2.   A line parallel to y = 2x + 2 will have the same slope.  This means the slope of the new line will also be 2.  

To determine the equation of the new line, we can use the given point  to find the y intercept of the new line:

y = 2x + b

Use x = -1 and y =3 to find b (or the y intercept ) of the new line:

3 = 2 * (-1) + b

3= -2 + b

b=5

Therefore, the equation of the line passing thru (-1,3) with the same slope as that of y = 2x + 2 will be:

y = 2x + 5
