Here we use the equation

y = a(b)^x

Taking points (0,4), (1,2)

Substituting the point (0,4) , we will get

4 = a(b)^0
\\
4 = a(1)  \\
a =4

Substituting (1,2) we will get

2 = 4 (b)^1
\\
2/4 = b
\\
b = 1/2

So we have

a = 4, b = 1/2

Therefore , required equation is

y = 4(1/2)^x

The manufacturer of an energy drink spends $1.20 to make each drink and sells them for two dollars the manufacturer also has fix
dimulka [17.4K]

Let X be the number of energy drinks sold.

The manufacturer of an energy drink spends $1.20 to make each drink and sells them for two dollars the manufacturer also has fixed cost each month of $8000.

The manufacturing cost for X energy drinks is

1.20x

Fixed cost is $8000.

Therefore, cost function is

C(x)=1.20x+8000

Selling price of each drink is $2.

Therefore, the revenue function is

R(x)=2x

Hence, the revenue function is

R(x)=2x

Find the length of the third side. If necessary, round to the nearest tenth. 10 14 ​
abruzzese [7]

Answer:

9.8 units

Explanation:

According to Pythagoras theorem, the square of length of the hypotenuse is equal to the sum of squares of lengths of other two sides.

Let the third side be x units.

Then,

x² + 10² = 14²

=> x² + 100 = 196

=> x² = 196 - 100

=> x² = 96

=> x = √96

=> x = 4√6

=> x = 9.79....

=> x = 9.8 (Rounding to the nearest tenths)

So, the length of the third side is 9.8 units.

In one town, 47% of all voters are Democrats. If three
34kurt

Answer:

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the all voters are democrats

The probability that the all voters are democrats

p = 47% =0.47

q = 1-p =1-0.47 = 0.53

<u><em>Step(ii):-</em></u>

Let 'X' be the random variable in binomial distribution

P(X=r) = n_{C_{r} } p^{r} q^{n-r}

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

n=3 and r=3

P(X=3) = 3_{C_{3} } (0.47)^{3} (0.53)^{3-3}

P(X=3) = 1 (0.47)^{3}

P(X=3) = 0.1038

<u>Final answer:-</u>

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

<u></u>
