For the function f defined above, what is the value of f(-1)

Answer: 3

Step-by-step explanation:

Given: A sample of 100 production workers is obtained. The workers are classified by gender (male, female) and by age (under 20, 20−29, 30−39, and 40 or over).

Here,

Total classes as per gender: k = 2 (male female)

Total classes as per age : m = 4  (under 20, 20−29, 30−39, and 40 or over)

Now , the degree of freedom = (k-1) ( m-1)

=  (2-1) (4-1)

= (1)(3)

= 3

Hence, there are 3 degree of freedom.

Answer:

1. $183

2.30 + 9t

Step-by-step explanation:

Guaranteed wage =$30

Additional amount that Brooklyn earns from tips depends on the number of tables she waits on that day.

Each table Brooklyn waits on =$9

1. How much would Brooklyn expect to earn in a day on which she waits on 17 tables

Total wage= guaranteed wage + tips on each table

Total wage=$30 + $9x

Where x= number of tables Brooklyn waits on

If she waits on 17 tables

Total wage=$30 + $9x

=30 + 9(17)

=30+153

=183

Total wage=$183

2. How much would Brooklyn expect to make in a day when waiting on t tables?

Total wage=$30 + $9x

When x=t

Total wage= 30+9(t)

=30+9t

Total wage=30 + 9t

|y-4|

Answer:

a.   y = 6

b.  RS = 44

    ST = 37

    RT = 81

Step-by-step explanation:

RS = 7y + 2

ST = 5y + 7

RT = 14y - 3

find:

a.  y

b.  RS, ST, RT

RS + ST = RT

7y + 2 + 5y + 7 = 14y - 3

group like terms

7y + 5y + 2 + 7 = 14y - 3

12y + 9 = 14y - 3

9 + 3 = 14y - 12y

12 = 2y

y = 12/2

y = 6

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

b.

RS = 7(6) + 2

RS = 44

ST = 5(6) + 7

ST = 37

RT = 14(6) - 3

RT = 81

Answer:

a.   y = 6

b.  RS = 44;     ST = 37;     RT = 81

Step-by-step explanation:

RS + ST = RT

7y + 2 + 5y + 7 = 14y - 3

group like terms

7y + 5y + 2 + 7 = 14y - 3

9 + 3 = 14y - 12y

12 = 2y

y = 12/2

y = 6

plug in values to solve RS,  ST,  RT

RS = 7(6) + 2 = 44

ST = 5(6) + 7  = 37

RT = 14(6) - 3  = 81

Answer:

15, 22, 88

Step-by-step explanation:

I assume you mean the second number is 7 more than the first.  Write the system of equations:

x + y + z = 125

y = x + 7

z = 4y

Substitute the third equation into the first.

x + y + 4y = 125

x + 5y = 125

Substitute the second equation.

x + 5(x + 7) = 125

6x + 35 = 125

6x = 90

x = 15

Solve for the other variables.

y = 22

z = 88

Because both the x and y variables are associate with a value, you don’t just add 3x and 2x.

You have:

3x^5y^8 + 2x^5y^7

Apply the exponent rule a^b+c = a^ba^c

This means x^5y^8 = x^5y^7y

Now you have:

3x^5y^7y + 2x^5y^7

Since they both now have an x^5y^7 in them factor the out of both:

When you take that out it’d both numbers you are left with 3y + 2

The final answer is: X^5y^7(3y +2)

5y = ZW - ZC

Conditional statements are statements that are either true or false, based on certain conditions.

The value of c is true

The condition is given as:

If A and B, then C

Where:

[tex]\mathbf{A = false}[/tex]

[tex]\mathbf{B = false}[/tex]

The reverse means that:

If not A and not B, then C

This means that:

[tex]\mathbf{not\ A = not\ false}[/tex]

[tex]\mathbf{not\ B = not\ false}[/tex]

So, we have:

[tex]\mathbf{not\ A = true}[/tex]

[tex]\mathbf{not\ B = true}[/tex]

For an and condition to be true, both values must be true.

So, we have:

If not A and not B, then C

Substitute known values

If true and true, then C

Because both values are true, then the value of C will also be true

Answer:

-3.5

Step-by-step explanation:

An example is -3.5.

Answer:

60°

Step-by-step explanation:

Through point B draw a line m || AY || CX and take two points say E and F on left and right side of point B respectively.

Therefore,

m∠FBC + m∠XCB = 180°..(By interior angle property)

m∠FBC + 130° = 180°

m∠FBC = 180° - 130°

m∠FBC = 50°....(1)

Next,

m∠ABF = m∠BAY... (Alternate angles)

m∠ABC + m∠FBC = 110°

(since, m∠ABF = m∠ABC + m∠FBC)

m∠ABC + 50° = 110° (From equation 1)

m∠ABC = 110° - 50°

Answer:

-3x + 2y = 8

Simplifying

-3x + 2y = 8

Solving

-3x + 2y = 8

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

-3x + 2y + -2y = 8 + -2y

Combine like terms: 2y + -2y = 0

-3x + 0 = 8 + -2y

-3x = 8 + -2y

Divide each side by '-3'.

x = -2.666666667 + 0.6666666667y

Simplifying

x = -2.666666667 + 0.6666666667y

Answer:

z= 3.63

z for  significance level = 0.05 is ± 1.645

Step-by-step explanation:

Here p = 42% = 0.42

n= 500

We formulate our null and alternative hypotheses as

H0: p= 0.42     against Ha : p> 0.42 One tailed test

From this we can find q which is equal to 1-p= 1-0.42 = 0.58

Taking p`= 0.5

Now using the z  test

z= p`- p/ √p(1-p)/n

Putting the values

z= 0.5- 0.42/ √0.42*0.58/500

z= 0.5- 0.42/ 0.0220

z= 3.63

For one tailed test the value of z for  significance level = 0.05 is ± 1.645

Since the calculated value does not fall in the critical region we reject our null hypothesis  and accept the alternative hypothesis that more than 42%  people owned cats.

Answer:

C            Mark me as brainliest!!!

Step-by-step explanation:

Answer:

My answer is option C.

Step-by-step explanation:

Since you cannot eliminate it immediately then you will need to multiply it by each of the number to make them equal that means you will multiply the first equation by any number in the second equation that is you can use maybe -4 or 2 or 1. and then do the same to the other equation to make them equal...if you use 2 in the second equation for the first equation and you use 7 in the first equation for the second equation the you will make them equal which makes them easier to eliminate and then when you find y which is y=1/22 then you can substitute it into any of the equation and find your x which is x=13/11.

Answer: option c

Step-by-step explanation:

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Dividend paid (D) = $2

Growth rate (g) = 4% per annum = 0.04

Expected Dividend in each of the next 3 years :

1st year : $2 * 1.04 = $2.08

2nd year : $2.08 * 1.04 = $2.16

3rd year: $2.16 * 1.04 = 2.2464 = $2.25

B) If the discount rate for the stock is 12 percent, at what price will the stock sell?

Discount rate (r) = 12% = 0.12

Price of stock = Dividend / (r - g)

Price of stock = 2 / (0.12 - 0.04)

Price = 2 / 0.08 = $25

c. What is the expected stock price 3 years from now?

(2.25 * 1.04) / 0.08

2.34 / 0.08 = $29.25

D) If you buy the stock and plan to hold it for 3 years, what payments will you receive? What is the present value of those payments?

Dividend to be received from year 1 to 3

2.08, 2.16, 2.25

Stock price in 3rd year = 29.25

Present value :

(29.25/1.12^3) + (2.25/1.12^3) + (2.16/1.12^2) + (2.08 / 1.12^1) = 26.00

For year 1 :

D = 2.08

Stock price = 2.16/0.08 = 27

Present value (PV) = (27/1.12) + (2.08/1.12) = 25.96

Year 2 :

D = 2.16

Stock price = 2.25/0.08 = 28.125

cashflow = (2.16 + 28.125) = 30.285

PV = (28.125/1.12^2) + (2.16/1.12^2) + (2.08/1.12^1) = 26.00

Year 3:

D = 2.25

STOCK PRICE = 29.25

Total Cashflow = (2.25 + 29.25) = 31.5

PV = (31.5/1.12^3) + (2.25/1.12^3) + (2.16/1.12^2) + (2.08/1.12^1) = $27.60

Answer:

Step-by-step explanation:

Probability of rain = 34% = 0.34

Probability of wind = 38% = 0.38

Probability of wind and rain = 10% = 0.1

P(wind U rain) = p(wind) + p(rain) - p(both)

= 0.34 + 0.38 -1

= 0.62

The probability that it would be rainy or sunny in any given day in April is 62%

Answer: 91 students ride the bus

For this problem, you can set up a proportion where:

w = those who walk to school

r = those who ride the bus to school

[tex] \frac{w}{r} = \frac{w}{r} [/tex]

Then include the ratio (1:7) as a fraction (1/7) and the value that is known (13).

[tex] \frac{1}{7} = \frac{13}{x} [/tex]

Cross multiply (create an "x").

[tex]1 \times x = 7 \times 13[/tex]

[tex]x = 91[/tex]

Answer:

$1

Step-by-step explanation:

5 cans of corn  --  5 * $1 = $5

4 cases of water  --  4 * $4 = $16

4 pounds of meat  --  4 * $2 = $8

Paid with  --  $30

Change required  --  30 - 8 - 16 - 5 = $1

John's mom will get $13 change back from the grocery shopkeeper.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given that,

5 cans of corn ⇒  $1.00/can

So cost  5 × 1 = $5

4 cases of water ⇒ $4.00 (remember not given "each")

So cost ⇒ $4

4 pounds of meat ⇒ $2.00 per pound

So cost 4 × 2 = $8

Now,

Total cost = 5 + 4 + 8 = $17

So,

Change = 30 - 17 = $13

Hence "John's mom will get $13 change back from the grocery shopkeeper".
