Answer:

the nearest whole number​: 5

Step-by-step explanation:

(12 x 5) + (10 x 6) = 120

120 / 22 = 5.45

since the first digit of the fractional part is 4, that's less than 5.

So the nearest whole number is 5

Which number line represents the solution set for the inequality 3(8 – 4x) < 6(x – 5)?
diamong [38]

Answer:

  A number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right.

Step-by-step explanation:

We can start by dividing the inequality by 3 to get ...

  8 -4x < 2(x -5)

And we can divide by 2 to simplify further to ...

  4 -2x < x -5

Now, we can add 2x+5, which gives ...

  9 < 3x

and then divide by 3 again:

  3 < x

This is graphed on a number line as described above.

Zolol [24]

Answer:

e. 0.08

Step-by-step explanation:

In the question above, a certain quantity of goods was supplied while a specific quantity of goods was sold per week. In a given week, if the number of proportion sold is X, therefore:

f(x) = {Γ(4+2)/Γ(4)Γ(2) x^3 (1-x), 0≤x≤1 ; 0, elsewhere

and

P(X greater than 0.9) =  \int\limits^1_ {0.9} \, 20(x^{3} - x^{4}) dx = 20*{(y^4/4)[1,0.9] - (y^5/5)[1,0.9]} = 20*{(0.25 - 0.164) - (0.20 - 0.118)}  = 20*{0.086 - 0.0819} = 20*0.0041 = 0.082

Therefore the probability of the proportion sold is approximately 0.082

kiyo bought a pizza for 12.75 and four medium drinks to Pauli’s pizza. Define a variable and write an expression to represent th
Stels [109]

The total cost, if one drink costs $3 is $27.75

  • Let the cost of a pizza be x

  • Let the cost of a drink be y

If kiyo bought a pizza for 12.75 and four medium drinks to Pauli’s pizza, this expressed as x + 4y

Since a pizza costs $12.75, hence x = $12.75

The function becomes 12.75 + 5y

f(y) = 12.75 + 5y

To get the total cost if one drink costs $3, hence;

f(3) = 12.75 + 5(3)

f(3) = 12.75 + 15

f(3) = 27.75

Hene the total cost, if one drink costs $3 is $27.75
