Answer:

Number of 13 cents stamp = 14

Number of 29 cents stamp = 24

Number of 45 cents stamp = 16

Step-by-step explanation:

We are told he has 54 stamps in total.

These stamps are;13 cent, 29 cent, and 45 cent stamps.

Let's call number of 13 cent($0.13) stamp A

Call number of 29 cent($0.29) stamp B

Call number of 45 cent($0.45) stamp C

Thus;

A + B + C = 54

We are told the total value of the 3 stamps are $15.98.

Thus;

0.13A + 0.29B + 0.45C = $15.98 - - - (eq2)

Now we are told that if the number of 13 cent stamps is doubled, the new total value of his stamp collection would be $17.80.

Thus;

2(0.13A) + 0.29B + 0.45C = 17.8

0.26A + 0.29B + 0.45C = 17.8 - - - (eq 3)

Solving the 3 equations simultaneously, we have;

A = 14

B = 24

C = 16

We have;

Number of 13 cents stamp = 14

Number of 29 cents stamp = 24

Number of 45 cents stamp = 16

Answer: 20 dollars per ticket

Step-by-step explanation:

Divide the number 480 by 24.

480 ÷ 24 = 20

The answer is 20. Hope this helps!

Step-by-step explanation:

If 24 tickets cost $480 the cost of 1 is:

Let the unit be u

480 ÷ 24= u

[tex] \frac{480}{24} = u[/tex]

[tex]20 = u[/tex]

[tex]u = 20[/tex]

Hope this helps....

Hence the unit = 20

The requried, there are 240 possible ways the race can finish with a mouse placing first, second, and third.

To find the number of ways the race can finish with a mouse placing first, second, and third, we can use the concept of permutations.

Since the mouse is guaranteed to finish first, there are 5 mice to choose from for the first position.

Once the first place is determined, there are 4 mice left for the second position.

After the first two positions are filled, there are 3 mice left for the third position.

Now, we need to determine the order of the cats. There are 4 cats to choose from for the fourth position.

The total number of ways the race can finish with a mouse placing first, second, and third is given by the product of these choices:

Number of ways = 5 (for first place) * 4 (for second place) * 3 (for third place) * 4 (for fourth place)

Number of ways = 5 * 4 * 3 * 4

Number of ways = 240

There are 240 possible ways the race can finish with a mouse placing first, second, and third.

Answer:

the dimensions that will minimize the cost are; 25.2 ft × 25.2 ft × 12.6 ft

Step-by-step explanation:

If the length, width and height of the building are represented by a, b and c, then we have:

Volume = abc

We are given volume as 8000 ft³. Thus;

abc = 8000

Top area = ab

Front area = ac

Back area = ac

End walls area = bc

We are told that cooling costs will amount to $2/ft² for its top, front, and back, and $4/ft² for the two end walls.

Thus, cooling cost equation is;

X = 2(ab) + 2(ac) + 2(ac) + 4bc + 4bc

X = 2ab + 4ac + 4bc

Now, from the volume equation where abc = 8000.

c = 8000/ab

Thus;

X = 2ab + 4a(8000/ab) + 4b(8000/ab)

X = 2ab + 32000/b + 32000/a

To minimize, we will find the a and b derivative and set the equation to zero in both cases.

Thus;

dX/da = 2b - 32000/a² = 0

2b = 32000/a² - - - eq(1)

Also;

dX/db = 2a - 32000/b² = 0

2a = 32000/b² - - - (eq 2)

Making a the subject in eq 2 gives;

a = 32000/2b²

a = 16000/b²

Putting 16000/b² for a in eq (1) gives;

2b = 32000/(16000/b²)²

2b = 32000b⁴/256000000

2b = b⁴/8000

Multiply both sides by 8000 to get;

2b × 8000 = b⁴

16000b = b⁴

Divide both sides by b to get;

16000 = b³

b ≈ 25.2 ft

Putting 25.2 for b in a = 16000/b², we have;

a = 16000/25.2²

a ≈ 25.2

Putting a and b = 25.2 in the volume equation, we have;

25.2 × 25.2 × c = 8000

c = 8000/(25.2 × 25.2)

c = 12.6 ft

Thus, the dimensions that will minimize the cost are; 25.2 ft × 25.2 ft × 12.6 ft

The percentage is  [tex]p = 4.55\%[/tex]

Step-by-step explanation:

From the question we are told that

 The mean is [tex]\mu = 12.1 \ ounce[/tex]

  The standard deviation is  [tex]\sigma = 0.05 \ ounce[/tex]

    The value of soda each can claims to have is  [tex]X = 12 \ ounce[/tex]

Generally the z-score is mathematically represented  as

         [tex]z = \frac{ X- \mu }{\sigma }[/tex]

=>      [tex]z = \frac{ 12-12.1 }{0.05}[/tex]

=>      [tex]z = -2[/tex]

From the z table the area under the normal  curve representing the proportion of under filled cans is

      [tex]P(x <-2 \ or\ x > 2)= 0.0455[/tex]

Converting to  percentage

       [tex]p = 0.0455 *100[/tex]

=>    [tex]p = 4.55\%[/tex]

[tex]7.56\times 10^7\ \text{beats}[/tex]

Step-by-step explanation:

It is given that,

A person has an average heart rate of 72.0 beats/min.

We need to find how many beats does he or she have in 2.0 years, t = 2 Y

Converting years to min.

[tex]t=2\text{year}\times \dfrac{365\ \text{days}}{\text{year}}\times 24\dfrac{h}{\text{day}}\times \dfrac{60\text{min}}{\text{hour}}\\\\t=1051200\ \text{min}[/tex]

So, no of beats in 2 years is given by :

[tex]b=72\ \text{beats/min}\times 1051200\ \text{min}\\\\b=7.56\times 10^7\ \text{beats}[/tex]

Hence, the required answer is [tex]7.56\times 10^7\ \text{beats}[/tex].

Answer:

The sum of the integers less than 100 that have both 6 and 9 as divisors is 270

Step-by-step explanation:

To determine the integers less than 100 that have both 6 and 9 as divisors,

First, we will list the multiples of 6 and 9 that are less than 100, and the common multiples will give the integers less than 100 that have both 6 and 9 as divisors.

Multiples of 6 less than 100 are:

6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, and 96.

Multiples of 9 less than 100 are:

9, 18, 27, 36, 45, 54, 63, 72, 81, 90, and 99.

Hence, the integers less than 100 that have both 6 and 9 as divisors are 18, 36, 54, 72 and 90.

Then, the sum of the integers less than 100 that have both 6 and 9 as divisors is

18 + 36 + 54 + 72 + 90 = 270

Hence, the sum of the integers less than 100 that have both 6 and 9 as divisors is 270.

The probability is 0.9545

Step-by-step explanation:

To find this probability, we shall use the z-score formula

Mathematically;

z-score = (x - mean)/SD/√n

where mean = 20

SD = 5

n = 100 and so √100 = 10

So for 19, we have ;

(19-20)/5/10 = 1/0.5 = -2

For 21, we have

(21-20)/5/10 = 1/0.5 = 2

So the probability we want to calculate is

P( -2 < z < 2)

we can use the standard normal distribution table for this

Using this table;

P(-2<z<2) = 0.9545

Answer:

0.12

Step-by-step explanation:

This is the answer because:

1) First, rewrite the expression including the x value

1.2(0.1)

2) Next, we know 1.2 x 1 is 1.2, but since we have one decimal point in 0.1, we have to move the decimal point in 1.2 once to the left. This will make the answer 0.12

Answer:

0.4532

Step-by-step explanation:

Given the question :

Find the percentage of area under a normal curve between the mean and the given number of standard deviations from the mean.1.68

Number of standard deviations from the mean = 1.68

I. 68 standard deviations below the mean :

Mean = 0(normal distribution)

P(Z < 0) = 0.5

1.68 standard deviations above the mean = + 1.68

P(Z < 1.68) = 0.95352

P(0 < x < Z) = (0.95352 - 0.5) = 0.4532
