Answer:

Rs 1311

Step-by-step explanation:

1100 + 50 = 1150

1150 * 114%

NB : since the profit is 14% means it is 14% hence 114% = 100% + 14% meaning the 100% original amount + the 14% profit

= Rs 1311

a) The mean number of radioactive atoms that decayed in a day is approximately 69.28 atoms. and b) the probability that on a given day, 50 radioactive atoms decayed is approximately 2.314685e-47.

a. To find the mean number of radioactive atoms that decayed in a day, we can divide the total number of atoms decayed over 365 days by the number of days:

Mean number of radioactive atoms decayed per day = Number of atoms decayed / Number of days

Mean number of radioactive atoms decayed per day = 25,272 atoms / 365 days

Mean number of radioactive atoms decayed per day ≈ 69.28 atoms

Therefore, the mean number of radioactive atoms that decayed in a day is approximately 69.28 atoms.

b. To find the probability that on a given day, 50 radioactive atoms decayed, we can use the Poisson distribution. The Poisson distribution is often used to model the number of events occurring in a fixed interval of time or space.

The formula for the Poisson distribution is:

P(X = k) = [tex](e^(-λ) * λ^k) / k![/tex]

Where:

P(X = k) is the probability that k events occur,

e is Euler's number, approximately 2.71828,

λ is the average number of events occurring in the given interval,

k is the number of events we are interested in.

In this case, the average number of radioactive atoms decayed in a day is approximately 69.28 atoms (calculated in part a). Therefore, λ = 69.28.

Substituting the values into the Poisson distribution formula:

P(X = 50) =[tex](e^(-69.28) * 69.28^50)[/tex] / 50!

Calculating [tex]e^(-69.28):[/tex]

[tex]e^(-69.28)[/tex] ≈ 2.67048178576e-31

Calculating [tex]69.28^50:[/tex]

[tex]69.28^50[/tex] ≈ 2.64267020807e+80

Calculating 50! (factorial of 50):

50! ≈ 3.04140932017e+64

Substituting these values back into the formula:

P(X = 50) ≈ (2.67048178576e-31 * 2.64267020807e+80) / 3.04140932017e+64

P(X = 50) ≈ 2.314685e-47

Therefore, the probability that on a given day, 50 radioactive atoms decayed is approximately 2.314685e-47.

The amount for renting SCUBA equipment for 1 hour and 15 minutes is (1) $40.63, including an up-front fee of $25 and an hourly rate of $12.50.

To calculate the amount for renting SCUBA equipment for 1 hour and 15 minutes, we need to consider the up-front fee and the hourly rate.

The up-front fee is $25, which is a fixed cost.

The additional fee for each hour is $12.50. Since we have 1 hour and 15 minutes, we can consider it as 1.25 hours.

Therefore, the total cost can be calculated as:

Total cost = up-front fee + (hourly rate × number of hours)

Total cost = $25 + ($12.50 × 1.25)

Total cost = $25 + $15.63

Total cost = $40.63

Hence, the amount for renting the SCUBA equipment for 1 hour and 15 minutes is $40.63.

Therefore, the correct answer is: (1) $40.63

xz^20 / y^15

Step-by-step explanation:

x^-5*y^4*z^18

------------------------

x^-6*y^19*z^-2

We are dividing so we subtract the exponents

First simplify the x terms

x^ -5 / x^ -6 = x^( -5 - -6) = x^ (-5+6) = x

Then simplify the y terms

y^ 4 / y^ 19 = y^( 4 - 19) = y^ (-15)

Finally simplify the z terms

z^ 18 / z^ -2 = z^( 18 - -2) = z^ (18+2) = z^20

x y ^ -15 z^20

The positive exponent terms are in the numerator and the negative exponent terms are in the denominator ( they change to positive exponents)

Answer:

5 students

Step-by-step explanation:

85 has the stem of 8.

The only leaf in stem 8 that has a number higher than the leaf 5 is 8.

The stem 9 is higher than the stem 8 so all of it's leaves are higher than 85.

There are 4 leaves under the stem 9 and there is one leaf in stem 8 that's higher than 5.

So there are 5 students that have a score higher than 85.

The value of b is 2.

To find the value of b, we need to equate the equations of the semi-circle and the parabola.

The equation of the semi-circle is given as fx = √(9 - x²).

The equation of the parabola is given as gx = b - (1/4)x².

Since both graphs represent the same function, we can equate them and solve for the value of x:

√(9 - x²) = b - (1/4)x²

To simplify the equation, let's square both sides:

9 - x² = (b - (1/4)x²)²

Expanding the right side of the equation:

9 - x² = b² - 2b(1/4)x² + (1/16)x⁴

Combining like terms:

9 - x² = b² - (1/2)bx² + (1/16)x⁴

Since the two sides of the equation are equal for all values of x, the coefficients of each power of x must be equal. Comparing the coefficients, we have:

-1 = -b/2          (coefficient of x² term)

0 = 1/16          (coefficient of x⁴ term)

From the coefficient of the x² term, we can solve for b:

-b/2 = -1

b/2 = 1

b = 2

(p−3)⋅(3p+2)

Step-by-step explanation:

STEP 1 :

Equation at the end of step 1

(3p2 -  7p) -  6

STEP 2 :

Trying to factor by splitting the middle term

2.1     Factoring  3p2-7p-6  

The first term is,  3p2  its coefficient is  3 .

The middle term is,  -7p  its coefficient is  -7 .

The last term, "the constant", is  -6  

Step-1 : Multiply the coefficient of the first term by the constant   3 • -6 = -18  

Step-2 : Find two factors of  -18  whose sum equals the coefficient of the middle term, which is   -7 .

-18 + 1  = -17  

-9 +2 = -7 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -9  and  2  

                    3p2 - 9p + 2p - 6

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

                   3p • (p-3)

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

                   2 • (p-3)

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

                   (3p+2)  •  (p-3)

            Which is the desired factorization

Final result :

 (p - 3) • (3p + 2)
