It represents the probability for fT (s)ds T ?t:FT(t)=Pr{T ?t}.Show that if T has an upper boundM:T ?M,then ?T ? = ? 1 ? F (t) dt. 0
Answers
T has an upper bound M: T ≤ M, then ∫T ≤ M fT (t) dt = 1 - F(M).
Let's discuss it further below.
To show that if T has an upper bound M: T ≤ M, then ∫T ≤ M fT (t) dt = 1 - F(M), we can use the fact that ∫fT (t) dt = F(T).The probability density function (pdf) of T is denoted by fT (t), and the cumulative distribution function (cdf) of T is denoted by FT (t). It represents the probability that T is less than or equal to t.
Mathematically, FT(t) = P(T ≤ t) = ∫0t fT (s) ds.
If T has an upper bound M, then P(T ≤ M) = F(M), since T cannot exceed M. Since P(T ≤ M) is a probability, it must be equal to 1, since there is no chance of T being greater than its upper bound. Therefore, F(M) = 1.
Now, we need to prove that ∫T ≤ M fT (t) dt = 1 - F(M). Since we know that F(M) = 1, this is equivalent to showing that ∫T ≤ M fT (t) dt = 0.
Consider the following:
∫T ≤ M fT (t) dt = ∫0M fT (t) dt [since T is less than or equal to M]
= F(M) - F(0) [using the fundamental theorem of calculus]
= 1 - F(0) [since F(M) = 1]
Now, we need to show that F(0) = 0. This is because there is no chance that T can be negative, and so P(T ≤ 0) = 0. Therefore, F(0) = 0.
Substituting this value into the expression above, we get:
∫T ≤ M fT (t) dt = 1 - F(0) = 1 - 0 = 1
Thus, we have shown that if T has an upper bound M: T ≤ M, then ∫T ≤ M fT (t) dt = 1 - F(M).

Let x represent the number of times more than the number of baskets Greta made that Jacinda made.
x can be obtained by dividing the number of baskets Jacinda made by the number of baskets Greta made:

14. Find the reciprocal of 20.95 to4 decimal places using the tables of reciprocals (1mk)
Answers
The reciprocal of 20.95 to 4 decimal places using the table of reciprocals is 0.0478.
Reciprocal of a numberTo find the reciprocal of 20.95, we can look up the reciprocal of 20.9 or 21 in the table and then interpolate to get a more accurate value for 20.95.
reciprocal of 20.9 = 0.04784reciprocal of 21 = 0.04762To interpolate, we can calculate the difference between 20.95 and 20.9, which is 0.05, and the difference between the reciprocals of 20.95 and 20.9, which is 0.00009.
Then we can use the formula:
reciprocal of 20.95 = reciprocal of 20.9 + (difference / interval) x (reciprocal of 21 - reciprocal of 20.9)
where interval is the difference between the numbers in the table (which is 0.1 in this case).
Thus:
reciprocal of 20.95 = 0.04784 + (0.05 / 0.1) x (0.04762 - 0.04784)
= 0.04784 + 0.025 x (-0.00022)
= 0.04784 - 0.0000055
= 0.0478345
In other words, the reciprocal of 20.95 to 4 decimal places using the tables of reciprocals is 0.0478.

Susan wants to make pumpkin bread and zucchini bread for the school bake sale. She has 15 eggs and 16 cups of flour in her pantry. Her recipe for one loaf of pumpkin bread uses 2 eggs and 3 cups of flour. Her recipe for one loaf of zucchini bread uses 3 eggs and 4 cups of flour. She plans to sell pumpkin bread loaves for $5 each and zucchini bread loaves for $4 each. Susan wants to maximize the money raised at the bake sale. Let x represent the number of loaves of pumpkin bread and y represent the number of loaves of zucchini bread Susan bakes.
What is the objective function for the problem?
P = 15x + 16y
P = 5x + 7y
P = 5x + 4y
P = 4x + 5y
Answers
The amount of money raised can be calculated by multiplying the number of pumpkin bread loaves (x) by the selling price of each pumpkin bread loaf ($5), and adding it to the product of the number of zucchini bread loaves (y) and the selling price of each zucchini bread loaf ($4).
Therefore, the objective function for this problem is:
P = 5x + 4y
So, the correct option is:
P = 5x + 4y

Step-by-step explanation:
A. Since 7 and 11 are both rational, the sum and difference are rational.
B. Since 14 and 11 are both rational, the sum and difference are rational.
C. Since 7 is rational and StartRoot 11 EndRoot is irrational, the sum and difference are irrational.
D. Since StartRoot 7 EndRoot is irrational and 11 is rational, the sum and difference are irrational.
p² – 14p – 72 = 0
p² – 14p = 72
p² – 14p + 49 = 72 + 49
p² - 14p + 49 = 121
(p - 7)² = 121
find the square root of both sides
√(p - 7)² = √121
p - 7 = ±11
p = +11 - 7 or p = -11 - 7

a report says that the average amount of time a 10-year-old american child spends playing outdoors per day is between 20.02 and 25.36 minutes. what is the margin of error in this report?
Answers
The actual average time spent playing outdoors by 10-year-old American children could be 2.67 minutes higher or lower than the reported range of 20.02 to 25.36 minutes.
The margin of error in the report stating that a 10-year-old American child spends an average of 20.02 to 25.36 minutes playing outdoors per day can be calculated by subtracting the lower value from the higher value and dividing by 2. In this case, the margin of error is :
To find the margin of error, we need to calculate the halfway point between these two values.
(25.36 - 20.02) / 2 = 2.67
Therefore, the margin of error is approximately 2.67 minutes. This means that the actual average time spent playing outdoors by 10-year-old American children could be 2.67 minutes higher or lower than the reported range of 20.02 to 25.36 minutes.
Thus, the actual average time spent playing outdoors by 10-year-old American children could be 2.67 minutes higher or lower than the reported range of 20.02 to 25.36 minutes.

A student sets up the following equation to convert a measurement. (The ? stands for a number the student is going to calculate.) Fill in the missing part of this equation. (−7.0×104 s2g⋅m2)⋅ΠΠ=? s2kg⋅m2
Answers
The missing part of the equation is \(-7.0\times10^4 s^2kg⋅m^2 / 1000000.\)
What is the value of the missing part in the equation?To fill in the missing part of the equation, let's analyze the given information and the desired conversion. The equation is:
\((-7.0\times 10^4 s^2g⋅m^2)\cdot \pi = ? s^2kg\cdot m^2\)
In this equation, we have a quantity expressed in\(s^2g\cdot m^2\) units on the left-hand side. To convert it to \(s^2kg\cdot m^2\) units, we need to multiply it by a conversion factor.
To perform the conversion, we can use the fact that 1 kg is equal to 1000 g. Therefore, the conversion factor we need is:
1 kg / 1000 g
To ensure that the units cancel out correctly, we need to square this conversion factor because we have \(s^2g\cdot m^2\) on the left-hand side. So the missing part of the equation is:
\((-7.0\times 10^4 s^2g\cdot m^2)\cdot \pi = (-7.0\times 10^4 s^2g\cdot m^2)\cdot (1 kg / 1000 g)^2\)
Simplifying this expression, we get:
\((-7.0\times10^4 s^2g\cdot m^2)\cdot \pi = -7.0 \times10^4 s^2kg\cdot m^2 / 1000000\)
Therefore, the missing part of the equation is \(-7.0 \times 10^4 s^2kg\cdot m^2 / 1000000.\)

Find the length of a rectangle that has a width of 3.9 cm and an area of 25.311 cm².
Answers
Answer:
Length = 6.49 cm
Step-by-step explanation:
The formula for area of a rectangle is
A = lw, where
A is the area in units squared,l is the length,and w is the widthSince we're already given the area and width and want to find the length, we can first rewrite the area formula in terms of l:
A/w = l
Now, we can plug in 25.311 for A and 3.9 for w to solve for l, the length:
25.311 / 3.9 = l
6.49 cm = l
We can check that 6.49 is the correct length by plugging everything into the regular area formula and checking that we get 25.311:
25.311 = 6.49 * 3.9
25.311 = 25.311
