Determine the null hypothesis and the alternate hypothesis: ************************** The August 2008 edition of Academy of Management Journal featured an investigation of the performance and timing of corporate acquisitions. The investigation discovered that in a random sample of 2778 firms, 748 announced one or more acquisitions during the year 2000. Does the sample provide sufficient evidence to indicate that the true percentage of all firms that announced one or more acquisitions during the year 2000 is less than 30%

Answers

Answer 1

Answer:

Following are answer to these question:

[tex]\LARGE H_0: p = 30 \%\\\\\LARGE H_A: p < 30 \%[/tex]

Step-by-step explanation:

Even though researchers try and check whether the real percentage of all companies announcing one or more purchases that year 2000 is less than 30%, the invariant hypothesis therefore becomes as follows:

[tex]\LARGE H_0: p = 30 \%\\\\\LARGE H_A: p < 30 \%[/tex]

WILL GIVE BRAINLIEST! PLS HELP! A 6-sided die with sides numbered 1 through 6 is tossed. A penny is then tossed. If the penny comes up heads, the value of the die is multiplied by 2. Otherwise, the value of the die is left unchanged.

What is the probability that the outcome is less than 6?

Answers

Answer:

[tex]\frac{7}{12} = 0.5833[/tex] = 58.33% probability that the outcome is less than 6

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

For the penny there are two outcomes, and for the die there are 6. So 2*6 = 12 total outcomes.

If the penny is tails, there are 5 outcomes which are less than 6. If it is heads, as the value is multiplied by 2, only 2 values of the die(1 or 2) will be below 6 after being multiplied by 2. So 5 + 2 = 7 total outcomes

What is the probability that the outcome is less than 6?

[tex]p = \frac{7}{12} = 0.5833[/tex]

[tex]\frac{7}{12} = 0.5833[/tex] = 58.33% probability that the outcome is less than 6

Assume a bank loan requires an interest payment of $85 per year and a principal payment of $1,000 at the end of the loan's eight-year life. What would be the present value of this loan if it carried a 10 percent interest rate?

Answers

Answer:

$919.98

Step-by-step explanation:

To solve using a financial calculator do

N=8

I/Y=10

PMT=85

FV=1000

CMPT PV get 919.98

To do by hand find the present value of the interst payments

85*(1-(1/1.1)^8)

which is 453.4687

Find the present value of the final ballon payment

1000*(1/1.1)^8

which is 466.507

take the sum

466.507+453.4678= 919.98

A fair coin is flipped 10 times. What is the probability that the first flip comes up heads or exactly five flips come up heads (or both)

Answers

i guess 1/2 since there are 2 sides of a coin

The probability for the given event is P = 0.75

How to get the probability?

The probability for flipping both sides of the coin is exactly the same one because we have an even coin.

The probability of getting the first flip heads up is just 0.5, as we can expect.

The probability that exactly 5 flips come heads up is:

P = C(10, 5)*(0.5)^10 = (0.5)^10*(10*9*8*7*6)/(5*4*3*2*1) = 0.25

Then, adding these two, the total probability is:

p = 0.5 + 0.25 = 0.75

and k in the general equation.
y = a3x - h + k
h =

Answers

Answer:

Let's solve for h.

y=a3x−h+k

Step 1: Flip the equation.

a3x−h+k=y

Step 2: Add -a^3x to both sides.

a3x−h+k+−a3x=y+−a3x

−h+k=−a3x+y

Step 3: Add -k to both sides.

−h+k+−k=−a3x+y+−k

−h=−a3x−k+y

Step 4: Divide both sides by -1.

−h

h=a3x+k−y

Answer:

h=a3x+k−y

Let's solve for k.

y=a3x−h+k

Step 1: Flip the equation.

a3x−h+k=y

Step 2: Add -a^3x to both sides.

a3x−h+k+−a3x=y+−a3x

−h+k=−a3x+y

Step 3: Add h to both sides.

−h+k+h=−a3x+y+h

k=−a^3x+h+y

Answer:

k=−a^3x+h+y

Step-by-step explanation:

The required values are h = 1 and k = 4 the given cube root function.

What is the cube root function?

The cube root function is a function that takes the cube root of its input. The formula for the cube root function is:

f(x) = ∛x

The graph is given in the question, as shown.

To find the symmetric center of the cube root function, we need to find the point on the function that is equidistant from the two opposite sides of the function graph.

Since the given cube root function is an odd function, it is symmetric about the point (1, 4).

So, the symmetric center of the cube root function is the point (1, 4).

Thus, h = 1 and k = 4

Therefore, the required values are h = 1 and k = 4 the given cube root function.

An employer wants to determine the amount of job satisfaction experienced by his employees. Which sampling
method is most likely to result in undercoverage?

Answers

Answer:

C: Employees are assigned to one of four pay scales. Randomly select a pay scale and survey every employee in that pay scale

Step-by-step explanation:

Looking at the given options, the one that will likely result in undercoverage will be option C. This is because even after assigning employees to any of the 4 payscales, when randomly selecting for survey, he picked only one pay scale and surveyed every on there. Since he didn't include at least one person in the other pay scales, he will not have covered every pay scale which he will need to make a conclusion on job satisfaction experienced by his employees.

Use the given graph to determine the domain , range etc.

Explanation :

Domain is the set of x values on the graph

The graph starts at x=0 and goes on .

So domain is [0,∞)

Range is the set of y values on the graph

The graph starts at y=-2 and it goes down

Range is [-2,-∞)

X intercepts are the points where the graph crosses or touches x axis

The graph does not cross the x axis

X intercept is none

Y intercepts are the points where the graph crosses or touches  y axis

The graph touches y axis at -2

Y intercept is (0,-2)

find the lateral area of a triangular prism with a height of 8 centimeters, and with bases having sides that measure 4 cm, 5 cm, and 6 cm

Answers

Answer:

120 cm²

Step-by-step explanation:

Applying,

A = Ph................... Equation 1

Where A = Literal Area of the triangular prism, P = Perimeter of the base, h = height.

But,

P = a+b+c............... Equation 2

Where a, b, c represent the three sides of the triangular base

Therefore,

A = h(a+b+c)............... Equation 3

From the question,

Given: h = 8 cm, a = 4 cm, b = 5 cm, c = 6 cm

Substitute these values into equation 3

A = 8(4+5+6)

A = 8(15)

A = 120 cm²

HELP!!! WILL GIVE BRAINLIEST +LIKE AND 5 STARS ANSWER THE QUESTION IN THE PICTURE

Answers

Answer:

13) B

14) A

Step-by-step explanation:

13) Knowing that the interior angles of a triangle add up to 180, we can see that angle A is 53°. To find length c, we can use either sine or cosine. Let's use sine:

sin 37° = b/c = 15.9/c ---> c = 15.9/sin 37 = 26.4

To solve for side a, use cosine:

cos 37° = a/26.4 ---> a = 26.4cos37 = 21.1

14) Again, knowing that the interior angles of a triangle add up to 180, we know that angle B is 52°. This time,let's use cosine (although you may choose sine if you want):

cos 38° = b/16 ---> b = 16cos38 = 12.6

To find side a, use sine:

sin 38° = a/16 ---> a = 16sin38 = 9.9

Find the slope and the y-intercept of the line. 6x + 3y = -3 Write your answers in simplest form​

Answers

Answer:

[m] slope = -2

[b] y-intercept = -1 ; (0, -1)

[y = mx + b] slope-intercept = -2x – 1

Step-by-step explanation:

Given the algebraic equation 6x + 3y = -3 currently in standard form:

Ax + By = C →

By = C – Ax →

By = -Ax + C →

y = -Ax / B + C / B →

y = (-A / B)x + (C / B) →

y = mx + b →

m = -A / B. b = C / B.

6x + 3y = -3

↓ ↓ ↓

A = 6. B = 3. C = -3.

[Substitute]

m = -A / B. b = C / B

m = -(6) / (3). b = (-3) / (3)

↓ ↓

m = -2. b = -1.

↓. ↓

Slope = -2. y-intercept = -1.

_______________________

Slope is ∆y/∆x [change in y over the change in x] = y2 – y1 / x2 – x1.

The y-intercept is the point where x is 0.

The easiest way to determine this is to substitute 0 in for x in an equation and solve for y.

This means that the y intercept in coordinate form is (0, b).

two pipes with lengths of 42 inches and 54 inches respectively are to be cut in pieces of equal lengths. what is the greatest possible length of these pieces so that no part of either pipe is left over in inches

Answers

Answer: 6

Step-by-step explanation:

Since we are informed that two pipes with lengths of 42 inches and 54 inches respectively are to be cut in pieces of equal lengths and we want to know the number of pieces that they can be cut into.

This question simply means that we need to find the factors of both 42 and 54 and choose the highest.

42 = 1, 2, 3, 6, 7, 14, 21, and 42.

54 = 1, 2, 3, 6, 9, 18, 27, and 54.

Therefore, the highest common factor is 6. Therefore, the greatest possible length will be 6 inches
