Answer:

54

Step-by-step explanation:

multiply 9 and 7 which is 63. then multiply 63 by 150 which is 9,450. then multiply 25 and 7 which is 175. then divide 175 and 9,450. and the answer is 54. Yw!!

We need to write and solve an algebraic equation to find the final company's balance.

The answer is: The final balance is -$275.

Let's see how to get that.

First, we know that the company earns $150 per week for 9 weeks, then the total amount of money that the company earns in these 9 weeks is:

$150*9 = $1,350

Then the company losses $65 per week for 25 weeks, then the amount that the company losses is:

$65*25 = $1,625

The final balance will be the difference between what the company earned and what the company lost, then the final balance is:

balance = $1,350 - $1,625 = -$275

This means that the company's final balance is -$275.

I just answered the problem on a quiz

Answer:

(a) The unit circle is centered at (0,0) with a radius of 1.

(b) The equation of a circle of radius r, with a center located at (0,0):

x²+ y² = r².

(c) (i) P(1,0)

    (ii) P(0,1)

    (iii) P(-1,0)

    (iv) P(0,-1)

Step-by-step explanation:

Part (a)

The unit circle is centered at (0,0). This point is the origin.

The radius of the unit circle is 1

The term "unit" means "one", which describes the radius length.

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

Part (b)

The equation of the unit circle is x^2+y^2 = 1

The general equation of any circle is (x-h)^2+(y-k)^2 = r^2

In this case, the unit circle has center (h,k) = (0,0) and radius r = 1.

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

Part (c)

The following four points are on the unit circle

As shown below in the diagram. The idea is to plug each given coordinate into the equation from part (b), and solve for the missing variable.

For example, if we know x = 1, then...

x^2+y^2 = 1

1^2+y^2 = 1

1+y^2 = 1

y^2 = 1-1

y^2 = 0

y = sqrt(0)

y = 0

Meaning x = 1 leads to y = 0. So (x,y) = (1,0) is one point on the circle. The other parts are handled in a similar fashion.

−s2+2st−t2−s+t

Step-by-step explanation:

−(s−t)−(s−t)2  

distributed would be

−s+t+−s2+2st+−t2

Answer:

Below in bold.

Step-by-step explanation:

-(s - t) - (s - t)^2       Take out  (s - t):

= (s - t)( -1 - (s - t)

= (s - t)(t - s - 1). <----  Factored form.

Or, if you want to  expand the expression:

-(s - t) - (s - t)^2

= - s + t - (s^2 - 2st + t^2)

= -s^2 + 2st - t^2 - s + t.

Step-by-step explanation:

H0: u = 150

H1: u ≠ 150

Total sum = 15933.24

N = 100

Mean = 15933.24/100

= 159.3324

σ² = 25954.03 - (159.3324)²/100

σ² = 556.213

σ = √556.213

σ = 23.8162

Testing hypothesis

t = (bar x - u)/ σ/√n

= 159.3324-150/23.8162/√100

= 3.91

We will have a p value of 0.02

0.0002 < 0.01

We reject null hypothesis at 1% level of significance

C. Mean = 159.3324

Se= 2.3936

Df = 100-1 = 99

Critical value at 0.01 = +-2.626

T = x-u/s.e

= -2.626 =( x -150)/2.3936

When we cross multiply and solve this

X = 143.714 for the lower tail

2.626 = (x-159)/2.3936

= 156.286 for upper tail.

We therefore reject H0 at

Bar X <= 143.71

Bar X >= 156.286

At 10%

Critical t = 1.660

-1.660 = (x - 150)/2.3936

Solving this ,

X =146.02 at the lower tail

1.660 = (x-150)/2.3936

X = 153.97

We reject H0 at

X<= 146.03

X>=153.97

Answer:

The simultaneous inequation representing the recomended storage temperature is:

[tex]50\,^{\circ}F \leq T \leq 55.4\,^{\circ}F[/tex]

Step-by-step explanation:

In this case, the statement must be represented mathematically by a simultaneous inequation, in which temperature must be equal to or greater than 10 ºC, expressed in Fahreheit degrees, and equal or less than 13 ºC, expressed in Fahrenheit degrees.

Bounds can be converted into Fahrenheit degrees from Celsius degrees:

[tex]T_{F} = \frac{9}{5} \cdot T_{C}+32\,^{\circ}F[/tex] (Eq. 1)

Where:

[tex]T_{C}[/tex] - Temperature, measured in Celsius degrees.

[tex]T_{F}[/tex] - Temperature, measured in Fahrenheit degrees.

Lower bound ([tex]T_{C} = 10\,^{\circ}C[/tex])

[tex]T_{F} = \frac{9}{5}\cdot (10\,^{\circ}C) + 32\,^{\circ}F[/tex]

[tex]T_{F} = 50\,^{\circ}F[/tex]

Upper bound ([tex]T_{C} = 13\,^{\circ}C[/tex])

[tex]T_{F} = \frac{9}{5}\cdot (13\,^{\circ}C) + 32\,^{\circ}F[/tex]

[tex]T_{F} = 55.4\,^{\circ}F[/tex]

The simultaneous inequation representing the recomended storage temperature is:

[tex]50\,^{\circ}F \leq T \leq 55.4\,^{\circ}F[/tex]
