Answer:

-16

Step-by-step explanation:

because y varies directly with 4 when you remove 8 from 4 you get -4 and when you remove it from -8 you get -16

The value of y is 8 for the given condition.

Linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. Generally, the equation is of the form Ax+B=0.

For the given situation,

The value of "y" varies directly with "x" and y = -8 when x = 4.

First we need to form the equation for this condition as  [tex]y=kx[/tex].

Here, x=4 and y=-8

⇒ [tex]-8=k(4)[/tex]

⇒ [tex]k=-2[/tex]

Now substitute the value of k and x=-4 in the above equation to get the value of y,

⇒ [tex]y=kx[/tex]

⇒ [tex]y=(-2)(-4)[/tex]

⇒ [tex]y=8[/tex]

Hence we can conclude that the value of y is 8 for the given condition.

Answer:

(a) 0.0668

(b) $638.74

Step-by-step explanation:

Let X denote the tips earned by a waiter.

It is provided that X follows a left-skewed distribution with mean, μ = $10.60 and standard deviation, σ = $6.60.

It is also provided that, the waiter usually waits on about n = 50 parties over a weekend of work.

According to the Central Limit Theorem if we have a population with mean μ and standard deviation σ and we take appropriately huge random samples (n ≥ 30) from the population with replacement, then the distribution of the sum of values of X, i.e ∑X, will be approximately normally distributed.  

Then, the mean of the distribution of the sum of values of X is given by,  

 [tex]\mu_{S}=n\mu\\[/tex]

And the standard deviation of the distribution of the sum of values of X is given by,  

[tex]\sigma_{S}=\sqrt{n}\sigma[/tex]

As the sample size is large, i.e. n = 50 > 30, the Central Limit Theorem can be used to approximate the sampling distribution of total tips by the normal distribution.

The mean and standard deviation are:

[tex]\mu_{S}=50\times 10.60=530\\\\\sigma_{S}=\sqrt{50}\times 6.60=46.67[/tex]

(a)

Compute the probability that he will earn at least $600 as follows:

[tex]P(S\geq 600)=P(\frac{S-\mu_{S}}{\sigma_{S}}\geq \frac{600-530}{46.67})\\\\=P(Z>1.50)\\\\=1-P(Z<1.50)\\\\=1-0.93319\\\\=0.06681\\\\\approx 0.0668[/tex]

Thus, the probability that he will earn at least $600 is 0.0668.

(b)

Let x represents his earnings on the best 1%  of such weekends.

That is, P (X < x) = 0.99.

⇒ P (Z < z) = 0.99

The corresponding z-score is, 2.33.

Compute the value of x as follows:

[tex]z=\frac{S-\mu_{S}}{\sigma_{S}}\\\\2.33=\frac{x-530}{46.67}\\\\x=530+(2.33\times 46.67)\\\\x=638.7411\\\\x\approx 638.74[/tex]

Thus, on the best 1%  of such weekends the waiter earned $638.74.

Answer: 4.9

Step-by-step explanation:

The height of the bookshelf is 4.3 feet and the height of the desk is 2.45 feet.

Simultaneous equations are any one or more equations that can have the same number of unknowns and be solved concurrently. The system of equations is a simultaneous equation.

Given:

A bookshelf sits on top of a large desk.

Together, their height is 6.75 feet.

The difference between their heights is 1.85 feet.

Let the height of the bookshelf = x and the height of the desk = y.

x + y = 6.75   {equation 1}

x - y = 1.85    {equation 2}

Add both equations,

we get,

2x = 6.75 + 1.85

2x = 8.6

x = 4.3

And from equation 2,

y = 2.45

Therefore, the solution is x =4.3 and y = 2.45.

Step-by-step explanation:

The price of a new cell phone = $225

With the extended warranty, the total cost comes to $289.

We need to find the percent of the purchase price is the price of the warranty. It can be calculated as follows :

[tex]\%=\dfrac{|\text{purchase price-extended warrenty price}|}{\text{purchase price}}\times 100\\\\=\dfrac{|225-289|}{225}\times 100\\\\=28.45\%[/tex]

So, the percent of the purchase price is 28.45%.

a. y = 40x + 35

b. 35 represents the one time fee

c. The 40x represents the monthly fee

d. f(x) represents the amount you have paid after an amount of months

Step-by-step explanation:

Answer:

1. n = 4

2. n = -29

3. n = -28

4. n = -48

5. n = -22

6. n = 97

7. n = 220

8. n = -18

9. n = 36

Step-by-step explanation:

1. -n = -4

Multiply both by -1 to get n = 4

2. 12 + n = -17

Subtract 12 from both sides of the equation to get n = -29

3. -n/14 = 2

Multiply by 14 on both sides of the equation to get -n = 28

Multiply -1 on both sides of the equation to get n = -28

4. -42 = n + 6

Subtract 6 from both sides of the equation to get -48 = n or n = -48

5. -4n = 88

Divide -4 on both sides of the equation to get n = -22

6. n + -3 = 94

Add 3 to both sides of the equation to get n = 97

7. 11 = -n/-20

Multiply by -20 on both sides of the equation to get -220 = -n or -n = -220

Multiply -1 on both sides of the equation to get n = 220

8. -108 = 6n

Divide by 6 on both sides of the equation to get -18 = n or n = -28

9. 67 = 31 + n

Subtract 31 from both sides of the equation to get 36 = n or n = 36

Answer:180

Step-by-step explanation:

Answer:

Step-by-step explanation:

Approximate rate of change:

The slope of the line is 1 / 2. The equation of the line is y = 1/ 2 x + 3.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that the line passes through points (8, 7) and (4, 5). The slope of the line will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 5 - 7 ) / ( 4 - 8 )

Slope = -2 / -4

Slope = 1 / 2

Calculate the y-intercept,

y = mx + c

5 = 1 / 2 x 4 + c

c = 5 - 2 = 3

The equation is written as,

y = mx + c

y = 1/2x + 3

Therefore, the slope of the line is 1 / 2. The equation of the line is y = 1/ 2 x + 3.

The price of a pair of jeans that has on sale for 45% off with the original price of $85 is $46.75.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

A pair of jeans originally cost $85 but you are on sale for 45% off. Then the price of a pair of jeans will be

→ 0.55 × $85
