Answer:

I don't see any inequality or a question.

Step-by-step explanation:

I suspect you want to know the minumum number of cups to sell in order to raise $1000 and pay off the company its $260

        c(10.5) - 260 > 1000

                     c  >  (1000 + 260) /10.5

                     c >  120 cups

Answer: 0.8015

Step-by-step explanation:

Let F= event that a person has flu

H= event that person has a high temperature.

As per given,

P(F) =0.35

Then P(F')= 1- 0.35= 0.65               [Total probability= 1]

P(H | F) = 0.90

P(H|F') = 0.12

By Bayes theorem, we have

[tex]P(F|H)=\dfrac{P(F)\timesP(H|F)}{P(F)\timesP(H|F)+P(F')\timesP(H|F')}\\\\=\dfrac{0.35\times0.90}{0.35\times0.90+0.65\times0.12}\\\\=\dfrac{0.315}{0.315+0.078}\approx0.8015[/tex]

Required probability = 0.8015

Y=x^2-2x-8

Step-by-step explanation:

rgbrgbrgbgbeefweuvhuuvhduvwg

The standard form of the equation y=(x-1)²-9 is y=x²-2x-8

Two or more expressions with an Equal sign is called as Equation.

y=(x-1)²-9 equation is in the form of a quadratic equation

where y is the unknown variable and x is the known variable.

The equation can be written in standard form by expanding the (x-1)² term and combining like terms.

y=(x-1)²-9

y=x²+1-2x-9

Combine the like terms

y=x²-2x-8

The expanded form of the equation is y=x²-2x-8

Hence, the standard form of the equation y=(x-1)²-9 is y=x²-2x-8

Answer:

$100.4

Step-by-step explanation:

Compound Interest Formula:

A = P[tex]([/tex]1 + [tex]\frac{r}{100}[/tex][tex])^{t}[/tex]

=> A = 100 x ( 1 + [tex]\frac{0.4}{100}[/tex])^1 = 100.4 (If they asked ... interest rate ... per year, if not then depends - most likely to be days and therefore you will need to change 1 year = 365 days and you will also need to change 1 in the formula above to 365, then you will get the right ans)

D 98°

Step-by-step explanation:

3(31) + 5 = 98

Answer:

Monday - 4 hours

Wednesday - 14 hours

Step-by-step explanation:

'h' = hours worked on Monday

'2 + 3h' = hours worked on Wednesday

h + 2 + 3h = 18

4h = 16

h = 4  (Monday)

18 - 4 = 14 (Wednesday)

Answer:

Hello, this would be a vertical angle graph. Since this graph is a supplementary graph since it stretches about 180 degrees, you would take both 7x and x+20 and set it equal to 180 like this:

7x+x+20=180

Then, you combine the xs and you would get this:

8x+20=180

Then, subtract 20 from both sides like this:

8x=160

Lastly, you would divide 8 by both sides and get x which is:

x=20

Answer:

[tex]\frac{5}{16}[/tex]

Step-by-step explanation:

1) Find the total number of marbles

5 blue + 6 red + 3 black + 2 yellow

= 16 marbles

2) To find the probability of selecting a blue marble, divide the number of blue marbles by the number of total marbles:

5 blue marbles ÷16 marbles

[tex]= \frac{5}{16}[/tex]

Therefore, the probability of selecting a blue marble is [tex]\frac{5}{16}[/tex].

Answer:

The height of the tank is 0.5 yards.

Step-by-step explanation:

To determine what is the height, in yards, of a cylindrical water tank that holds 1,884 cubic yards of water and has a diameter of 120 feet, knowing that the volume of a cylinder is equal to pi multiplied by the radius squared, multiplied by the height, the following calculation must be done:

1 foot = 0.3333 yards

R = Diameter / 2

R = 120/2 = 60

3.14 x 60 ^ 2 x H = 1,884

3.14 x 3,600 x H = 1,884

3.14 x 1,200 x H = 1,884

3.768 x H = 1.884

H = 1,884 / 3,768

H = 0.5

Therefore, the height of the tank is 0.5 yards.

Answer:

[tex]\frac{5}{12}[/tex]

Step-by-step explanation:

The given problem is a subtraction problem between fractions. The first step in a problem like this is to convert both fractions to a common denominator. In other words, multiply both the numerator and denominator of a fraction by the same value such that the denominator of one of the fractions is the same as the other fraction. The numerator of a fraction is the value over the fraction bar, whereas the denominator is the value under it. Multiplying any fraction by a number over itself is the same as multiplying it by one, thus, the equation will remain true, and be equivalent to the original expression.

[tex]\frac{13}{12}-\frac{2}{3}[/tex]

Convert to a common denominator,

[tex]\frac{13}{12}-(\frac{2}{3}*\frac{4}{4})[/tex]

[tex]\frac{13}{12}-\frac{8}{12}[/tex]

Now perform the subtraction, subtract one numerator from the other, remember, do no perfrom any more operations with the denominators,

Step-by-step explanation:

Plug in 2 for x

(2)^3+6(2)^2+3(2)-5=

Answer:

B

Step-by-step explanation:

Remark

F(2) means that wherever you see an x on the right side of the equal sign, you substitute 2 for.

Suppose the question was f(2) = 3x + 5

Put a 2 where the x is.

f(2) = 3*2 + 5

f(2) = 6 + 5

f(2) = 11

Equation

f(x) = x3 + 6x2 + 3x -5.

Solution

f(2) = 2^3 + 6*2^2 + 3*2 - 5

f(2) =  8 + 6*4 + 6 - 5

f(2) = 8 + 24 + 1

f(2) = 33
