Answer:

P(2) = 1/18

P(3) = 1/9

P(4) = 1/6

P(5) = 1/6

P(6) = 1/6

P(7) = 1/6

P(8) = 1/9

P(9) = 1/18

Step-by-step explanation:

Each die has six possible outcomes, so both dice together have 6*6 = 36 outcomes:

(1,1), (1,1), (1,2), (1,2), (1,3), (1,3),

(2,1), (2,1), (2,2), (2,2), (2,3), (2,3),

(3,1), (3,1), (3,2), (3,2), (3,3), (3,3),

(4,1), (4,1), (4,2), (4,2), (4,3), (4,3),

(5,1), (5,1), (5,2), (5,2), (5,3), (5,3),

(6,1), (6,1), (6,2), (6,2), (6,3), (6,3).

The sum of the values for each outcome is:

2, 2, 3, 3, 4, 4,

3, 3, 4, 4, 5, 5,

4, 4, 5, 5, 6, 6,

5, 5, 6, 6, 7, 7,

6, 6, 7, 7, 8, 8,

7, 7, 8, 8, 9, 9.

To find the probability of each sum, we just need to divide the number of times this sum appears over the total number of possibilities (36), so we have:

P(2) = 2/36 = 1/18

P(3) = 4/36 = 1/9

P(4) = 6/36 = 1/6

P(5) = 6/36 = 1/6

P(6) = 6/36 = 1/6

P(7) = 6/36 = 1/6

P(8) = 4/36 = 1/9

P(9) = 2/36 = 1/18

A population of mice is increasing exponentially. On Monday there were 120 mice. One month later there were 132 mice. Write a fu
den301095 [7]

Answer:

y =120*1.1^x

r = 10\% --- Percentage increase

Step-by-step explanation:

Given

Let

x \to months

y \to mice

So, we have:

(x_1,y_1) = (0,120) --- Monday

(x_2,y_2) = (1,132) --- One month later

Required

The function

The function is represented as:

y = ab^x

In (x_1,y_1) = (0,120), we have:

120 =a * 1

120 =a

Rewrite as:

a = 120

In (x_2,y_2) = (1,132), we have:

132 = a * b^1

132 = a * b

Substitute a = 120

132 = 120 * b

Solve for b

b = \frac{132}{120}

b = 1.1

Recall that:

y = ab^x

Hence, the function is:

y =120*1.1^x

To get the monthly percentage increase (r), we have:

y = a(1 + r)^x

Compare to: y = ab^x

So:

1+r =b

Make r the subject

r = b-1

r = 1.1-1

r = 0.1

Express as percentage

r = 0.1*100\%

r = 10\%

What is -4d 3 + 28d 2 - 4d
Svetlanka [38]

Answer: 20d + 5

Step-by-step explanation:

First we need to combine like terms.

In this equation we can see that they're are 3 numbers containing the letter D we have -4, -4, 28.

We're going to combine -4 and -4 to get -8 and then combine -8 to 28 getting 20d

Afterwards we're going to combine 3, 2 equaling 5.

SVETLANKA909090 [29]

Answer:

135 Adult tickets and 70 Child tickets sold

Step-by-step explanation:

135*10 (adult ticket price) = 1,350

70*3 (child ticket price) = 210

$1,350 + $210 = $1,560

135 + 70 = 205 tickets sold

If you invest x dollars at 3% intrest compounded annually ,then the amount A (x) of the investment after one year is A(x)=1.03x.
GarryVolchara [31]


The "compound amount" formula is A = P(1+r)^t.

Here, the Amount  A(x) is (x)(1+0.03)^1= 1.03x.

Please be clearer about what you are asking here.  I assume you just wanted to be told that you are right.
