Answer:

0% probability that a customer will be exactly 7.50 minutes in the record store.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.  

The probability of finding a value of at lower than x is:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

The probability of finding a value between c and d is:

[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]

The probability of finding a value above x is:

[tex]P(X > x) = \frac{b - x}{b - a}[/tex]

The uniform distribution is a continuous distribution, which means that the probability of an exact outcome is zero.

Uniformly distributed between 3 and 12 minutes.

This means that [tex]a = 3, b = 12[/tex]

What is the probability that a customer will be exactly 7.50 minutes in the record store?

Continuous distribution, so:

0% probability that a customer will be exactly 7.50 minutes in the record store.

Answer:

Joe: 18 years old

Tim: 14 years old

Answer:

See below

Step-by-step explanation:

-3x+2y = -6 [1]

-2x + y = 6 [2]

For [1], solve for X.

-3x + 2y = -6

-3x = -6 - 2y

3x = 6 + 2y

x = 2 + (2/3)y

Plug x into [2]

-2(2+(2/3)y) + y = 6

-4 - 4/3y + y= 6

-4/3y + y= 10

-1/3y = 10

y = -30

9514 1404 393

Answer:

  (x, y) = (-18, -30)

Step-by-step explanation:

When choosing to solve by substitution, it is convenient if one of the variables has a coefficient of 1 or -1. Here, y has a coefficient of 1 in the second equation, making it easy to rearrange that equation to give an expression for y:

  y = 2x +6 . . . . . add 2x to the second equation

Using this expression, we can substitute for y in the first equation:

  -3x +2(2x +6) = -6

  x + 12 = -6 . . . . . . . . . simplify

  x = -18 . . . . . . . . . . . subtract 12

  y = 2(-18) +6 = -30 . . . . substitute into the equation for y

The solution is (x, y) = (-18, -30).

Answer:

The marked price was $ 7,777.77, and the selling price of it with VAT was $ 7,910.

Step-by-step explanation:

Given that 13% VAT is levied on a handicraft after 10% discount, if the VAT amount is $ 910, to find the marked price and selling price of it with VAT the following calculations must be performed:

13 = 910

100 = X

100 x 910/13 = X

91,000 / 13 = X

7000 = X

0.9 = 7000

1 = X

7000 / 0.9 = X

7,777.77 = X

Therefore, the marked price was $ 7,777.77, and the selling price of it with VAT was $ 7,910.

Answer:

−2√85/85

Step-by-step explanation:

The required value of the cosθ is −2√85/85. Option D is correct.

Given that,
The value of cosθ given that (−2, 9) is a point on the terminal side of θ is to be determined.

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.

here,
horizontal run b = -2, vertical rise p = 9
Slant height,
h = √ -[2]² + [9]²
h = √4 + 81
h = √85
Now,
cosθ = b / h
cosθ = -2 / √85
cosθ = -2 √85/85

Thus, the required value of the cosθ is −2√85/85. Option D is correct.

Answer:

90 numbers

Step-by-step explanation:

Considering the stipulations from the question, the layout for the 3-digit number is:

[tex]\underline{x}\:\underline{2}\:\underline{y}[/tex]

The hundreds digit, [tex]x[/tex], can be any number from 1-9 inclusive, which contains 9 numbers.

The tens digit, 2, is fixed, as stipulated from the problem, and therefore may only be one number, 2.

The ones digit, [tex]y[/tex], can be any number from 0-9 inclusive which gives 10 options.

Therefore, there are [tex]9\cdot 1\cdot 10=\boxed{90}[/tex] three digit numbers that have 2 as a tens digit.

Answer:

the right answer would be C

Answer:

Step-by-step explanation:

You first need to find the surface area of a completely open cylinder. That formula is

[tex]SA=2\pi rh[/tex] Using 3.14 for π, we find the area of the material that is needed to make this pipe:

SA = 2(3.14)(1)(30)

SA = 188.49 square feet.

If it costs $3.50 per square foot and you have 188.9 square feet, we multiply the cost per square foot times the number of square feet:

188.49(3.50) = $659.40, choice B.

[tex]➢ \: \: \dfrac{2(6 + b)}{2} [/tex]

Answer:

Problem:

If the average of b and c is 8, and d=3b-4, what is the average of c and d in terms of b?

Step-by-step explanation:

We are given (b+c)/2=8 and d=3b-4.

We are asked to find (c+d)/2 in terms of variable, b.

We need to first solve (b+c)/2=8 for c.

Multiply both sides by 2: b+c=16.

Subtract b on both sides: c=16-b

Now let's plug in c=16-b and d=3b-4 into (c+d)/2:

([16-b]+[3b-4])/2

Combine like terms:

(12+2b)/2

Divide top and bottom by 2:

(6+1b)/1

Multiplicative identity property applied:

(6+b)/1

Anything divided by 1 is that anything:

Step-by-step explanation:

in the small triangle

taking 60 as reference angle

b = [tex]10\sqrt{3}[/tex]

so

tan 60 = p/b

[tex]\sqrt{3}[/tex] = p/([tex]10\sqrt{3}[/tex])

30 = p

so

[tex]h^2 = p^2 + b^2\\ = 30^2 + (10\sqrt{3} )^2\\\\ = 900 + 300\\ = 1200\\so h^2 = 1200\\then, h = \sqrt{1200} \\ = 20\sqrt{3} \\so\\in bigger triangle\\\\h = x[/tex](taking 45 as reference angle)

so

in bigger triangle

b = 20[tex]\sqrt{3}[/tex]

so

tan 45 = p/b

1 = p/(20[tex]\sqrt{3}[/tex])

p = 20[tex]\sqrt{3}[/tex]

so h^2 = p^2 + b^2

so

h^2 = (20[tex]\sqrt{3}[/tex])^2 +( 20[tex]\sqrt{3}[/tex])^2

= 1200 + 1200

h^2 = 2400

h =[tex]\sqrt{2400}[/tex]

=20[tex]\sqrt{6}[/tex]

so x = 20[tex]\sqrt{6}[/tex]

This can be expressed as:

[tex](2*4^3)+(1*4^2)+(1*4^1)+(a*4^0) = 150\\128+16+4+a = 180\\148 + a = 150\\a = 150 - 148\\a = 2[/tex]

Hence the value of a is 2

Answer:

Step-by-step explanation:

If (8,2) and (0,0) are points on the line, the slope of the line is (2-0)/(8-0) = ¼.

y = ¼x

y = 1/4x is the equation of the  line passing through points (0, 0) and (8, 2)

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

slope of line passing through (0, 0) and (8, 2)

m=2/8

=1/4

Now let us find the y intercept in the equation.

2=1/4(8)+b

2=2+b

b=0

So equation will be y=1/4x.

Step-by-step explanation:

Given

For 10,000 residents, 17,000 police officers are hired

The ratio of Police officers and citizens is constant

So, for 35,000 citizens suppose x officers are hired

[tex]\Rightarrow \dfrac{17,000}{10,000}=\dfrac{x}{35,000}\\\\\Rightarrow x=1.7\times 35,000\\\\\Rightarrow x=59,500[/tex]
