Answer:

answer A. next=now •3

Step-by-step explanation:

Looking at the sequence 3, 9, 27, 81, you "see" a that each next number is formed by multiplying the current

number by 3. This is exactly what is stated in answer A. next=now •3

Answer:

A

Step-by-step explanation:

3,9,27,81......

This  is geometric sequence.

Common ratio = 2nd term / 1st term = 27/9 = 3

So, the next term is obtained by multiplying the current number by 3

Next = now * 3

car ​as the following utility​ function: ​U(X,Y)equals10Upper X squaredY where X is her consumption of​ Blu-ray disks with a pri
mr_godi [17]

Answer:

She consumes 30 blue ray disk and 60 DVD respectively.

Step-by-step explanation:

Consider the provided information.

U(x,y)=10x^2y

Calculate marginal utility of good

Differentiate with respect of x and y.

MU_x=20xy

MU_y=10x^2

Her consumption of​ Blu-ray disks (X) with a price of ​$40 and Y is her consumption of DVDs with a price of ​$10.

The ratio of marginal utility of good x to y is equal to the price ratio:

\frac{MU_x}{MU_y}=\frac{P_x}{P_y}

Substitute the respective values.

\frac{20xy}{10x^2}=\frac{40}{10}

\frac{2y}{x}=4

2y=4x

y=2x

She has ​$1800 with which to spend on the two goods.

Her consumption of​ Blu-ray disks (X) with a price of ​$40 and Y is her consumption of DVDs with a price of ​$10. She has ​$1800 with which to spend on the two goods.

Therefore, 40x+10y=1800

4x+y=180

Substitute the value of y in above equation.

4x+2x=180

6x=180

x=30

Thus, y=60

She consumes 30 blue ray disk and 60 DVD respectively.

When a fish is selected at random from a tank, the probability that it has a green tail is 0.36, the probability that it has red
Katarina [22]

Answer: 0.26

Step-by-step explanation:

As per given , we have

P(green tail) = 0.36

P(red fins) = 0.59

P(both a green tail and red fins ) = 0.21

Now, P(Neither red fin nor green tail )= 1 - P(either red fin or green tail )

<em>[P(neither A nor B)= 1- P(either A or B)]</em>

= 1-(P(green tail) +P(red fins)+P(both a green tail and red fins ))

<em>[P(A or B)= P(A)+P(B)-P(A and B)]</em>

= 1- (0.36+0.59-0.21)

= 1-(0.74)

= 0.26

Hence, the probability that the selected fish will not have a red fin or a green tail = 0.26

Find two numbers whose sum is 29 and whose difference is 15
gizmo_the_mogwai [7]
The two numbers are 22 and 7.
22 + 7 = 29
22 - 7 = 15
here is how we can find these numbers;
let a and b are two numbers
a + b = 29
a - b = 15
a   = 15 + b
now put this value of a in any of the equation
a + b = 29
15 + b  + b = 29
15 + 2b = 29
2b = 29 - 15
2b = 14
b = 7
now put the value of b to find the value of a;
a = 15 + b = 15 + 7 = 22
a = 22
