How much is 10% of 10 liters of milk​

Answer:

The value  is  [tex]E(X) =  \$ 1.7067 [/tex]

Step-by-step explanation:

From the question we are told that

   The  parameters  are  α = 3, θ = 0.5

    The cost of making a unit on the first day  is  c = $2

    The selling price of a  unit on the first day is  s = $5

    The selling price of a leftover unit on the second day is  v  = $ 1

Generally the profit of a unit on the first day is

        [tex]p_1 = 5 - 2[/tex]

           [tex]p_1 = \$3 [/tex]

The profit of a unit on the second day is

       [tex]p_2 = 1 - 2[/tex]

=>     [tex]p_2 = - \$1 [/tex]

Generally the probability of making profit greater than $ 1 is mathematically represented as

    [tex]P(X >  1 ) = Gamma (X ,\alpha , \theta)[/tex]

=>   [tex]P(X >  1 ) = Gamma (1 ,3 , 0.5)[/tex]

Now from the gamma distribution table  we have that

    [tex]P(X >  1 ) =  0.67668[/tex]

Generally the probability of making profit less than or  equal to  $ 1 is mathematically represented as

       [tex] P(X \le  1 ) = 1 - P(X >  1 )[/tex]

=>     [tex] P(X \le  1 ) = 1 - 0.67668[/tex]

=>     [tex] P(X \le  1 ) = 0.32332[/tex]    

So  the probability of making  $3  is    [tex]P(X >  1 ) =  0.67668[/tex]

and  the probability of making  -$1  is   [tex] P(X \le  1 ) = 0.32332[/tex]  

Generally the value of profit per day is mathematically represented as

      [tex]E(X) =  3 *  P(X >  1 )   +   (-1  *  P(X \le 1 ) )[/tex]

=>     [tex]E(X) =  3 * 0.67668   +   (-1  *  0.32332 )[/tex]

=>     [tex]E(X) =  \$ 1.7067 [/tex]

Answer:

x=24cm

y=20,78cm

Step-by-step explanation:

sen(30)=[tex]\frac{12}{x}[/tex]  ->  x*sen(30)=12 -> x=[tex]\frac{12}{sen(30)}[/tex]= 24cm

cos(30)=y/x -> cos(30)= y/24 -> y=24*cos(30)= 20,78cm

Answer: 75%

Step-by-step explanation:

Part =  52,500,000

Whole = 70,000,000

[tex]\frac{52,500,000}{70,000,000} =\frac{x}{100} \\[/tex]

Solve for x.

[tex]x=\frac{52,500,000*100}{70,000,000}[/tex]

[tex]x=\frac{5,250,000,000}{70,000,000}[/tex]

[tex]x=75[/tex]

Step-by-step explanation:

the answer is supplementary because congruent are slant angles

Answer:

y=3x-3

Step-by-step explanation:

since the line must pass through (0,-3), you must have the second number (or y intercept) in the equation be -3. since the slope must be 3 then it will be shown as 3x. put it all together to get y=3x-3. not sure what the -1 is doing there but y=3x-3 passes through (0,-3)

Answer:

No solution

Step-by-step explanation:

x = 2 + x - 2

x - x = 2 - 2

0 = 0

=》x has no solution.

Answer: 18 hours (Plz mark me brainlest)

Step-by-step explanation:

we know that

Amy's dad drove the car at a constant speed and travel 585 miles in 13 hours

so

using proportion

Find out how long would it have taken the family to travel 810 miles

Let

x -----> the time in hours to travel 810 miles

Answer:

18 hours; rate of speed 45 miles per hour

Step-by-step explanation:

585 miles/13 hours= 45 miles per hour

810 miles/45 miles per hour = 18 hours

Answer:

only students who have recess at 12 p.m. or later may go out

Step-by-step explanation:

Let the time after midnight be represented by t, and the temperature be y. Since the temperature increases by 1.2 degrees Fahrenheit each hour, the time taken to reach 32 degrees Fahrenheit can be gotten from:

y = 1.2t + 18

put y = 32

32 = 1.2t + 18

1.2t = 14

t = 14/1.2 = 11.67 hours

Since the recess starts at half hour or hour, hence the recess would start at t = 12 hours, i.e. at 12 p.m.

Hence only students who have recess at 12 p.m. or later may go out

Answer:

i know im late but here only students who have recess at 12 p.m. or later may go out

Step-by-step explanation:

We know that revenue= production=break even point

given that the expression for cost of production is

z=120+4x---------------1 cost of production

where x is the number of items produced

also the selling price per item is $5

The revenue generated from the production of x items is(let the revenue be y)

y=5x------------2 revenue equation

break-even is when y=z

120+4x=5x

solving for x we have

120=5x-4x

120=x

x=120items

Answer:

factor = x^3-5x+3

Step-by-step explanation:

you need to use long division to solve it.

Take 2 points

Slope:-

[tex]\\ \sf\longmapsto \dfrac{-2}{7}=\dfrac{-2}{7}=m[/tex]

Now find equation of line in point slope form

[tex]\\ \sf\longmapsto y=-2/7(x+7)[/tex]

[tex]\\ \sf\longmapsto y=-2/7x-2[/tex]

Put (0,0)

[tex]\\ \tt\Rrightarrow 0=0-2[/tex]

[tex]\\ \tt\Rrightarrow 0\neq -2[/tex]

shaded region is away from origin .

So the inequality is

[tex]\\ \sf\longmapsto y\leqslant -2/7x-2[/tex]

Answer:

Take 2 points

(-7,0)

(0,-2)

Slope:-

Now find equation of line in point slope form

Put (0,0)

shaded region is away from origin .

So the inequality is

this answer is correct i got it right when i used it.

Answer:

A.

Step-by-step explanation:

the slope of a line is behind the x in a linear equation.

f(x)=5x-2 is a linear equation

So, the slope of f(x) is 5.

Since A is the only choice with this answer, A is correct.

Answer:

First option

Step-by-step explanation:

Given the following question:

[tex]\frac{2}{3} y=\frac{1}{4}[/tex]

To find the answer we need to isolate the variable, in order to do that we need to use inverse of operations on this problem.

[tex]\frac{2}{3} y=\frac{1}{4}[/tex]
[tex]3\times\frac{2}{3} =2[/tex]
[tex]\frac{1\times3}{4} =\frac{3}{4}[/tex]
[tex]\frac{2y}{2} =y[/tex]
[tex]\frac{3}{4} \div2=\frac{3}{8}[/tex]
[tex]y=\frac{3}{8}[/tex]

Your answer is "y = 3/8" or the first option.
