What is the probability that the spinner will not land on a 5 or 8?

The order doesn't matter, so you could say "t+11 and t-9" to mean the same thing.

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

Explanation:

Think of two numbers that multiply to -99, but also add to 2. In other words, find two factors of -99 which add to 2. We'll use trial and error.

Here are all the ways to multiply to -99 using integers only:

Add up each factor pair to see which sum is equal to 2.

We can see that 11 and -9 are the two numbers we're after, so therefore, t^2+2t-99 factors to (t-9)(t+11). The order doesn't matter with the factor multiplication.

As a more efficient alternative method, you can use the quadratic formula to solve t^2+2t-99 = 0 to end up with t = 9 and t = -11. That would lead to the  two equations t-9 = 0 and t+11 = 0. Applying the zero product property then gets us (t-9)(t+11) = 0.

To help show that (t-9)(t+11) becomes t^2+2t-99, you can use the FOIL rule to expand that factorization out. This is one way to verify the answer.

The larger pool will hold is 100 times more gallons than the smaller pool

From the question, we are to determine how many times more gallons the larger pool holds than the smaller pool

From the given information,

Capacity of the larger pool = 2 × 10¹⁰ gallons

Capacity of the smaller pool = 2 × 10⁸ gallons

To determine how many times more gallons the larger pool  holds more than the smaller pool, we will simply divide the capacity of the larger pool by the capacity of the smaller pool

That is,

[tex]\frac{2 \times 10^{10} }{2 \times 10^{8}}[/tex]

= 10²

= 100

Hence, the larger pool will hold is 100 times more gallons than the smaller pool.

Answer:

To find X you'll need this formula Tan 30, and this one to find y cos 30.

Step-by-step explanation:

tan 30 = 9 / x.

tan 30*x = 9

x = 9 / tan 30

x = 15.58

To find y, the value of X will be needed, which is 15.5 that we just found.

Cos= A/H

Cos 30 = 15.58/ y

Cos 30 * y = 15.58

y = 15.58/ cos 20

y = 17.99

8/17

The SinL as a fraction in the simplest form is 8 / 17.

A triangle whose one is 90 degrees is considered a right-angled triangle. Pythagoras' theorem is applied only to the right-angled triangle.

Given:

The side NM = 16,

The side LM = 30,

By using Pythagoras' theorem, we can say that,

NL² = NM² + LM²

Substitute the values of NM and LM,

NL² = 16² + 30²

NL = 34,

For SinL = perpendicular side / hypotenuse side

SinL = NM / NL,

SinL = 16 / 34 or 8 / 17

Therefore, the SinL as a fraction in the simplest form is 8 / 17.

Answer:

x=0 and y=6

Step-by-step explanation:

First, you would solve x=y-6 for x.

x=y-6 so you substitute the x in -6x-2y=-12 with (y-6)

-6x-2y=-12 → -6(y-6)-2y=-12

Simplify both sides of the equation = -8y+36=-12

Add -36 to both sides to remove it = -8y+36+-36=-12+-36

-8y+36+-36=-12+-36 → -8y=-48

Divide both sides by -8 to remove it. [tex]\frac{-8y}{-8} =\frac{-48}{-8}[/tex] → y=6

I believe where you went wrong was with where you substituted y-6.

y-6 is the substitute for x so in parenthesis you would put (y-6) where x is in -6x-2y=-12 making the new equation -6(y-6)-2y=-12.

The height of the triangle is 15 centimeters.

Given the following data:

To find the height of the triangle:

Mathematically, the area of a triangle is given by the formula;

[tex]Area \;of\; a \;triangle = \frac{1}{2}[/tex] × [tex]base[/tex] × [tex]height[/tex]

Substituting the values into the equation, we have;

[tex]15 = \frac{1}{2}[/tex] × [tex]2[/tex] × [tex]height[/tex]

Height = 15 cm

Therefore, the height of the triangle is 15 centimeters.

Answer: 2600 cm^2

Step-by-step explanation:

FORMULA

Painting P area = Painting Q area +   1400

      so...

 40(3x-10)           =       30(x+15)        +   1400

 EXPAND                     EXPAND

 120x - 400          =       30x + 450     +   1400

                                                        SIMPLIFY

 120x-400            =        30x + 1850

         +400                             +400

 120x                    =         30x + 2250

 - 30x                             - 30x

   90x                   =                   2250      

DIVIDE BY 90              DIVIDE BY 90

     x                      =                   25

SO... Now we have to find the AREA of PAINTING P

LENGTH: (3x - 10)=  3(25) - 10 = 65cm

HEIGHT:  40cm

AREA OF PAINTING P = 65cm X 40cm = 2600cm^2

By solving a system of equations, we will see that the area of painting P is 2,600 cm^2

Remember that the area of a rectangle of length L and width W is:

A = L*W

Then the area of painting P is:

A = 40cm*(3x - 10)cm

The area of paint Q is:

A' = (30 cm)*(x + 15)cm

And que know that:

A = A' + 1400cm^2

Then we havea system of equations:

A = A' + 1400cm^2

A = 40cm*(3x - 10)cm

A' = (30 cm)*(x + 15)cm

First, we can replace the third equation into the first one to get:

A = (30 cm)*(x + 15)cm + 1400cm^2

And that must be equal to:

A = 40cm*(3x - 10)cm

So now we can solve:

40cm*(3x - 10)cm =  (30 cm)*(x + 15)cm + 1400cm^2

for x.

It gives:

120cm*x - 400cm^2 = 30cm*x + 1850 cm^2

120cm*x - 30cm*x = 1850cm^2 + 400cm2

x = (2250cm^2)/(90cm) = 25cm

Now that we know x, we can get the area of painting P.

A = 40cm*(3*25cm - 10cm) = 2,600cm^2

[tex]\implies f^{-1}(x) =-\dfrac{x}{4}-3 [/tex]

Step-by-step explanation:

Given :-

And we need to find out the Inverse of the function . Let us assume that f(x) = y . Now , firstly replace x with y and vice versa.

Function :-

[tex]\implies f(x) = -4x - 12 \\\\\implies y = -4x-12 [/tex]

Interchanging x and y :-

[tex]\implies x = -4y - 12 [/tex]

Solve out for y :-

[tex]\implies x = -4y - 12 \\\\\implies -4y = x +12 \\\\\implies y =\dfrac{x+12}{-4}\\\\\implies y =-\dfrac{x}{4}-3 [/tex]

Replace y with f-¹(x) :-

[tex]\implies f^{-1}(x) =-\dfrac{x}{4}-3 [/tex]

Hence the inverse of the function is -x/4-3 .

Answer:

88 sq cm

Step-by-step explanation:

A=(b1+b2) x H divided by 2

Answer:

1) If we have a point (x, y), the angle between the x-axis and a ray that goes from the origin to the point is defined by:

cos(θ) = x/(√(x^2 + y^2))

sin(θ) = y/(√(x^2 + y^2))

Then for the point:

(√(7)/4 , 3/4)

x = √(7)/4

y = 3/4

√(x^2 + y^2) = √((√(7)/4)^2 + ( 3/4)^2) = (1/4)*√(7 + 9) = 1

Then replacing these values in the above equations for the cosine and sine functions, we get:

cos(θ) = x/(√(x^2 + y^2)) = (√(7)/4)/1 = √(7)/4

sin(θ) = y/(√(x^2 + y^2)) = (3/4)/1 = 3/4

2) To find the period, we just need to find the distance between two peaks, or two x-intersects (such that the slope is the same).

Let's look at the graph.

We can see that at x = 0, the graph intersects the x-axis and increases

The next point where this happens is at x = π/3

Then the period of this function is:

P = π/3 - 0 = π/3

The period is π/3

Answer: 3 feet

Step-by-step explanation:

Here's the complete question:

The volume of the cylinder is 235.6 cubic feet the radius is 5ft. Find the height.

Note that Volume of a cylinder = πr²h

where Volume = 235.6 feet³

Radius = 5 feet

Height = Unknown

Then, we put the values back into the question and this will be:

V = πr²h

235.6 = 3.14 × 5² × h

235.6 = 3.14 × 25 × h

235.6 = 78.5 × h

h = 235.6 / 78.5

h = 3 feet

The height is 3 feet

  Women                           76             424               500

 Men                                 169            331               500

Total {occupation wise}      245            755             1000 [Grand Total]

1) Probability (any person in S & E) = Total people in S & E / Total people = 245 / 1000 = 0.245

2) Prob (woman & works in S & E) , ie P (W ⋂ S) =  Total women in S & E / Total people  =  76 /  100 = 0.76

3) Prob (woman or works in S & E), ie P (W U S) = P( Women) + P (S & E) - Prob (Women & SE), ie P (W) + P (S &E) - P (W ⋂ S) = ( 500 + 245 - 76 ) / 1000 = 669 / 1000 = 0.669

The probability that a randomly selected person works in an S&E occupation is 0.245.

The probability that a randomly selected person is a woman and works in an S&E occupation is 0.12.

The probability that a randomly selected person is a woman or works in an S&E occupation is 0.745

Probability determines the odds that an event would happen.

The probability that a randomly selected person works in an S&E occupation = total number of people that work in SE / total number of people= 245 / 1000 = 0.245.

The probability that a randomly selected person is a woman and works in an S&E occupation = (number of women / total number of people surveyed) x (number of people that work in SE / total number of people surveyed)

500 / 1000 x (245 / 1000) = 0.12

The probability that a randomly selected person is a woman or works in an S&E occupation = (number of women / total number of people surveyed) + (number of people that work in SE / total number of people surveyed)

= 500 / 1000 + (245 / 1000) = 0.745
