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.
how are Mass and distance related to gravity
Answer:

pls help now plz On your own paper, please write a fraction with x^-5*y^4*z^18 in the numerator and x^-6*y^19*z^-2 in the denominator. Simplify this fraction.
Answer:
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)
xz^20 / y^15

A lawnmower was purchased at rupees 1100 and rupees 50 were paid as transportation charges. It was sold at 14% profit. Find its selling price
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 project has an initial cost of $40,400, expected net cash inflows of $14,000 per year for 9 years, and a cost of capital of 12%. What is the project's NPV? (Hint: Begin by constructing a time line.) Do not round your intermediate calculations. Round your answer to the nearest cent.
Answer:
$59,750
Step-by-step explanation:
According to the given situation, the calculation of net present value is shown below:-
Net present value = Net cash inflows × PVIFA factor(9,12%) - Initial cost
= $14,000 × 7.1607 - $40,400
= $100,250 - $40,500
= $59,750
Therefore as per the situation for computing the net present value we simply applied the above formula.
farmer janet can plant nine feet of carrots in 15 minutes while her daughter Amy can plant 17 feet of carrots in half an hour.Justify your answer.
Answer:
a. Farmer janet
b.Farmer janet = 36 feet, daughter = 34 feet
Step-by-step explanation:
a. When moving both rates to the same common denominator we get 18/30 for janet and 17/30 for daughter
b. janet = 18/30 = 36/60, daughter = 17/30 = 34/60
Let f(x)= ax^2+bx+c and g(x)= ax^2-bx+c. If f(1) = g(1)+2 and f(2)=2, find g(2).
Answer:
first lets calculate f(1)=g(1)+2
a+b+c=a-b+c+2 so b=1
next lets calculate f(2)=2 remembering that we found b=1
4a+2*1+c=2 so c=-4a
Now lets find g(2)
g(2)=4a-2b+c= -c-2+c=-2 this is the final response
A vacation resort rents SCUBA equipment to certified divers. The resort charges an up-front fee of $25 and another fee of $12.50 an hour. What is the amount if you rent the SCUBA equipment for 1 hour and 15 minutes? • $40.63 $28.13 $50 $41
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

If the semi-circle and the parabola are the respective graphs of fx= square root of 9-x2,gx=b- 1/4 x2, find the value of b.
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

When studying radioactive material, a nuclear engineer found that over 365 days, 1,000,000 radioactive atoms decayed to 974,728 radioactive atoms, so 25,272 atoms decayed during 365 days a. Find the mean number of radioactive atoms that decayed in a day b. Find the probability that on a given day, 50 radioactive atoms decayed
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.
