The inverse operations used after the distributive property is B. subtraction then division.

<h3>How to illustrate the information?</h3>

The equation given goes thus:

5(x + 6) = 50.

5x + 30 = 50

5x = 20.

x = 4

Therefore, the inverse operations used after the distributive property is subtraction then division.

The cost of milk is expected to raise 106% over the next year
gulaghasi [49]

Answer: about $6.90


Step-by-step explanation: 106% of 3.35

100% of 3.35 is 3.35

6% of 3.35 is 0.201

Add them together and you get 3.551

When you round to the nearest cent, you get $3.55

After add 3.55 to 3.35 and you get $6.90

g: Consider the following game. A coin is flipped. If it lands tails we stop playing and winnothing. If it lands heads we spin a
galben [10]

Answer:

E[W] = $25 (assuming the currency is in dollars)

Var(W) = 1041.67

Step-by-step explanation:

Probability of winning first starts with the coin toss.

For a win, the coin needs to land on heads.

Probability of that = 1/2 = 0.5

Then probability of winning any amount = 1/100 = 0.01

Total probability of winning any amount = 0.5 × 0.01 = 0.005

But expected value is given by

E(X) = Σ xᵢpᵢ

where xᵢ is each amount that could be won

pᵢ is the probability of each amount to be won and it is the same for all the possible winnings = 0.005

So,

E(W) = Σ 0.005 xᵢ

Summing from 0 to 100 (0 indicating getting a tail from the coin toss). This could be done with dome faster with an integral sign

E(W) = ∫ 0.005 x dx

Integrating from 0 to 100

E(W) = [0.005 x²/2]¹⁰⁰₀

E(W) = [0.0025 x²]¹⁰⁰₀ = 0.0025(100² - 0²) = 0.0025 × 10000 = $25

Variance is given by

Variance = Var(X) = Σxᵢ²pᵢ − μ²

μ = expected value

We calculate the expression, Σxᵢ²pᵢ which is another sum from 0 to 100

Σxᵢ²pᵢ = Σ 0.005xᵢ²

Σ 0.005 xᵢ² = ∫ 0.005 x² dx

Integrating from 0 to 100

∫ 0.005 x² dx = [0.005 x³/3]¹⁰⁰₀ = [0.1667x³]¹⁰⁰₀ = 0.1667(100³ - 0³) = 1666.67

Var(W) = 1666.67 - 25² = 1666.67 - 625 = 1041.67.

Evaluate.<br><br> [42 ÷ (2 + 3 • 2)] + [4 • (36 – 52)]<br><br> I really need help!!!
juin [17]
Ok so first we do 2 + 3 = 5 * 2 = 10 / by 42 = 4.2

other side 36 - 52 = 16 * 4 = 64 now add     4.2 + 64 = 68.2

Anni [7]

Answer:

f(-4) = 6

f(0) = -6

f(1) = -4

On a coordinate plane, a parabola opens up. It goes through (negative 4.25, 10), has a vertex of (negative 0.5, negative 6.2), and goes through (3.25, 10). Solid circles appear on the parabola at (negative 4, 6), (negative 2, negative 4), (negative 1, negative 6), (0, negative 8), (1, negative 4), (2, 0), and (3, 6).

Step-by-step explanation:
