Step-by-step explanation:

Total No. of rolling each side of the 12-sided die= 12 x 12= 144 outcomes

No. of outcomes equals 10 are: (1, 9), (9, 1), (2, 8), (8, 2), (3, 7), (7, 3), (4, 6), (6, 4), (5, 5) = 9 outcomes.

No. of outcomes of rolling a No. >10: 144–9 = 135 outcomes.

Probability, Pr, of rolling a No. >10= 135/144

Pr (No. >10) = 0.9375 (to 4 dec. pl.)

Step-by-step explanation:

1. baseball + basketball = 240

2. tennisball + soccerball = 500

3. soccerball - basketball + tennisball = 455

4. baseball + tennisball = 215

Subtract 1 from 4

5. tennisball - basketball = -25

Rearrange 3

6. soccerball + tennisball - basketball = 455

Substitute 5 into 6

7. soccerball - 25 = 455

Solve

soccerball = 480

Answer:

Elephant 14%

Panda 18%

Tiger 29%

Bonobo 39%

Step-by-step explanation:

Divide each number by 2400 then multiply the answer by 100.  

The percentage of elephants, pandas, tigers, and bonobos are 14%, 18%, 29%, and 39% respectively.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

The zoo has some new exhibits.

In a survey, 2400 zoo attendants are asked to choose their favorite.

From the table:

The total number of animals = 336 + 432 + 696 + 936 = 2400

Percentage of Elephant = (336/2400)x100 = 14%

Percentage of Panda = (432/2400)x100 = 18%

Percentage of Tiger = (696/2400)x100 = 29%

Percentage of Bonobo = (936/2400)x100 = 39%

Thus, the percentage of elephants, pandas, tigers, and bonobos are 14%, 18%, 29%, and 39% respectively.

Answer:

Dimension of the Rectangle : 2W - 150 by W

Step-by-step explanation:

Given

Land Size = 150 metres

This land size represents the perimeter of the land

Let P = Perimeter

So, P = 150 m

To bisect the field into two equal halves means to divide length or width of the field into two equal halves

Let L = Length of the field

Let W = Width of the field

Assuming the length of the field is to be bisected., then the campground owner is left with 0.5L (i,e half of the length)

Perimeter of a rectangle is calculated by: 2(Length + Width)

P = 2(L + W) by substitution, becomes

150 = 2(0.5L + W) ----open bracket

150 = L + 2W ---- Male L the subject the formula

L = 2W - 150

The dimension of the largest area that can be enclosed id given by (L,W)

By substitution; the expression becomes

Dimension of the Rectangle : 2W - 150 by W

Step-by-step explanation:

Answer:

The answer to your question is Cost of a serving = $0.62

Step-by-step explanation:

Data

diameter = 3.5 in

height = 5 in

each serving = 15 in³

Cost of the can = $1.99

Process

1.- Calculate the volume of the can

Volume = πr²h

-Substitution

Volume = (3.14)(3.5/2)²(5)

-Simplification

Volume = (3.14)(3.062)(5)

-Result

Volume = 48.08 in³

2.- Use proportions and cross multiplication to find the cost of a serving.

                   48.08 in³ ---------------- $1.99

                         15  in³ ----------------  x

                          x = (15 x 1.99)/48.08

                          x = 29.85/48.08

                          x = $0.62

Answer:

1182 mg  to the nearest mg.

Step-by-step explanation:

22% is equivalent to 260 mg sodium, so

100% is equivalent to  260 * (100/22)

= 1181.82 mg.

what is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Examples of percentages are:

10% is equal to 1/10 fraction

20% is equivalent to ⅕ fraction

25% is equivalent to ¼ fraction

50% is equivalent to ½ fraction

75% is equivalent to ¾ fraction

90% is equivalent to 9/10 fraction

Given,

Dave determines the meal he ordered at the restaurant contains 22% of his daily sodium intake

Meal contains 260 mg of sodium

22% is equivalent to 260 mg sodium, so

100% is equivalent to  260 x ([tex]\frac{100}{22}[/tex])

= 1181.82 mg.

22% is equivalent to 260 mg sodium, so

100% is equivalent to  260 * (100/22)

= 1181.82 mg.

Answer:

The distance that represents it is 651.9 m.

Step-by-step explanation:

In order to calculate the distance that the wheel travelled we need to find the length of the circumference of the wheel. This is given by the following formula:

length = 2*pi*r = pi*d

Since the diameter of the wheel is 0.6 m we can find the length of the wheel that is:

length = 3.14*0.6 = 1.884 m

The wheel made 346 full turns, that means that the total distance is the number of turns multiplied by the length of the wheel.

distance = 346*1.884 = 651.9 m

The distance that represents it is 651.9 m.

Answer:

1.Robert borrowed  $ 5,500.00  

2.The amount Robert would repay next year is $ 11,576.69  

3.The interest rate on the loan is 7%

Step-by-step explanation:

The interest on the loan can be computed using compound annual growth

rate

CAGR=(EB/BB)^1/n-1

EB is ending balance of $8831.80 in year7

BB is the balance of year 5  $7714.03

n=7-5=2

CAGR=(8831.8/7714.03)^(1/2)-1

CAGR==1.070000427-1

CAGR=0.070000427

CAGR=7%

The amount borrowed can be computed using the PV formula

At year 0 year 5 amount of $7714.03 is the future value

rate of interest is 7%

number of years is 5

PV=$7714.03*(1+7%)^-5

PV=$ 5,500.00  

The amount Robert would pay next year is :

FV=$10,819.338(1+7%)^1

FV=$ 11,576.69  

We have been given the 5-number summary of a box plot that represents Coins in Collection. The five-number summary from left to right is 7, 16, 30, 36, 38.

We are asked to find the inter-quartile range of the given data.

We know that interquartile range is difference of upper quartile and lower quartile.

We know that the 5-point summary represents the lower data point, lower quartile, median, upper quartile and upper data point respectively.

We can see from our given 5 point-summary that lower quartile is 16 and upper quartile is 36.

Answer:

(x+3)(2x+7)

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 (2x2 +  13x) +  21

Step  2  :

Trying to factor by splitting the middle term

2.1     Factoring  2x2+13x+21

The first term is,  2x2  its coefficient is  2 .

The middle term is,  +13x  its coefficient is  13 .

The last term, "the constant", is  +21

Step-1 : Multiply the coefficient of the first term by the constant   2 • 21 = 42

Step-2 : Find two factors of  42  whose sum equals the coefficient of the middle term, which is   13 .

      -42     +     -1     =     -43  

      -21     +     -2     =     -23  

      -14     +     -3     =     -17  

      -7     +     -6     =     -13  

      -6     +     -7     =     -13  

      -3     +     -14     =     -17  

      -2     +     -21     =     -23  

      -1     +     -42     =     -43  

      1     +     42     =     43  

      2     +     21     =     23  

      3     +     14     =     17  

      6     +     7     =     13     That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  6  and  7

                    2x2 + 6x + 7x + 21

Step-4 : Add up the first 2 terms, pulling out like factors :

                   2x • (x+3)

             Add up the last 2 terms, pulling out common factors :

                   7 • (x+3)

Step-5 : Add up the four terms of step 4 :

                   (2x+7)  •  (x+3)

            Which is the desired factorization

Final result :

 (x + 3) • (2x + 7)

Answer:

The answer is 9 hours

Step-by-step explanation:

From the initial population of 180 cells, the number grows by 8% every hour for the first 9 hours.

This represents a increased population of 108% the previous population.

108% = 108/100 = 1.08

So the new population after n hours is

180 x 1.08^n

When population is 360

360 = 180 x 1.08^n

1.08^n = 2

Take log of both sides

n x Log1.08 = Log 2

n = Log 2/Log 1.08

n = 9
