To solve this problem, we use the t statistic. The z score is calculated as:
z = (x – u) / s
where x is the sample value = 53 and 77, u is the mean score = 65 while s is the standard deviation = 4
when x = 53
z = (53 – 65) / 4 = -3
From the standard distribution tables, the p value at z = -3 is:
P (z=-3) = 0.0013
when x = 77
z = (77 – 65) / 4 = 3
From the standard distribution tables, the p value at z = 3 is:
P (z=3) = 0.9987
The percentage P between the two would be the difference:
P (53 < x < 77) = 0.9987 – 0.0013 = 0.9974
Answer:
0.9974 or 99.74%
A box of cookies can hold 24 cookies, and a container can hold 75 boxes of cookies. write a program that prompts the user to enter the total number of cookies, the number of cookies in a box, and the number of cookie boxes in a container. the program then outputs the number of boxes and the number of containers to ship the cookies. note that each box must contain the specified number of cookies, and each container must contain the specified number of boxes. if the last box of cookies contains less than the number of specified cookies, you can discard it and output the number of leftover cookies. similarly, if the last container contains less than the number of specified boxes, you can discard it and output the number of leftover boxes.
The provided math problem involves writing a program that helps to calculate the number of cookie boxes and containers required to ship a specific number of cookies considering the capacity of each item. If there are leftover cookies that do not fill a box or if there are leftover boxes that do not fill a container, these are also calculated.
Explanation:This is a programming problem which requires logic to calculate the number of boxes and containers needed to ship a given number of cookies. Assume that 'total_cookies', 'cookies_per_box', and 'boxes_per_container' are user inputs. Initially, you should calculate the total boxes by 'total_boxes = total_cookies / cookies_per_box'. The floored division operator is applied to discard the last box if it contains less than the specified number of cookies. Then, calculate the total containers with 'total_containers = total_boxes / boxes_per_container'. Again, you use the floored division operator to discard the last container if it contains less than the specified number of boxes. Lastly, calculate the leftover cookies and boxes, which is done by applying the modulus operator. 'leftover_cookies = total_cookies % cookies_per_box' and 'leftover_boxes = total_boxes % boxes_per_container'.
The logic of the given program focuses on the calculation of boxes and containers needed to ship the given number of cookies keeping in consideration the capacity of each box and container. Also, the algorithm calculates the leftover cookies and boxes, if not enough to fill a box or container fully.

What is the value of x in the figure below? In this diagram, ΔABD ~ ΔCAD.
The value of x in the figure given is E. √70.
The answer is E. √70.
The two triangles are similar by the AAA Similarity Theorem, since they have two pairs of congruent angles, namely ∠ABD and ∠CAD, and ∠BAD and ∠CDA.
Since the triangles are similar, the ratio of corresponding sides is constant. In particular, the ratio of AD to CD is the same as the ratio of BD to AD.
We are given that AD = 14 and CD = 20, so the ratio of AD to CD is 14/20. We are also given that BD = x, so the ratio of BD to AD is x/14.
Setting these two ratios equal to each other, we get x/14 = 14/20, which simplifies to x = √70.
Here is a proof that shows why the two triangles are similar:
AAA Similarity: Triangles ABD and CAD have two pairs of congruent angles, namely <ADB> and <CAD>, because they are both right angles.
SSS Similarity: Triangles ABD and CAD have three pairs of corresponding sides that are proportional, namely AD/CD = 14/20, BD/AD = x/14, and AB/CD = √70/20. Therefore, the two triangles are similar by the SSS Similarity Theorem.

5. The dimensions, in inches, of a shipping box at We Ship 4 You can be expressed as width x, length x + 5, and height 3x - 1. The volume is about 7.6 f3. Find the dimensions of the box in inches. Round to the nearest inch. (Hint: 1 f 1,728 in.3)
To find the dimensions of the shipping box, calculate the volume in cubic inches, then set up and solve the volume equation x(x + 5)(3x - 1), substituting the given volume after conversion from cubic feet. Solve for x, then use it to find and round the box's dimensions.
Explanation:To find the dimensions of the shipping box, we need to calculate the volume using the given dimensions in inches and compare it to the provided volume in cubic feet. Recall that the conversion factor between cubic feet and cubic inches is 1 cubic foot equals 1,728 cubic inches. Firstly, convert the volume of the box from cubic feet to cubic inches: 7.6 cubic feet are 7.6 x 1,728 cubic inches.
Next, we can set up the volume equation for the box using the given dimensional expressions: volume = width x length x height, which for this box is x x (x + 5) x (3x - 1). Now we solve the equation for x given that the volume in cubic inches is equal to 7.6 x 1,728 inches.
Once x is found, we can determine the width, length, and height by plugging x back into the expressions x, x + 5, and 3x - 1, respectively, and rounding each to the nearest inch.
If f(x)= 2x+8 and g(x) = x^4, what is (g°f)(-3)?
The formula for the area a of a triangle is a equals 1 half b where is the base and h is the height. solve the formula for h and then find the height of a triangle whose area is 1768 square inches and whose base is 52 inches. round to the nearest tenth if necessary. height = inches
Area of triangle is given as:
A = (1/2) b * h
where b is base and h is height
So given that:
A = 1768 inches^2
b = 52 inches
Rearranging the equation to find for h:
h = 2 A / b
h = 2 * 1768 inches^2 / 52 inches
h = 68 inches

The perimeter of a rectangular concrete patio is 34 meters. the area is 70 square meters. what are the dimensions of the patio?
To find the dimensions of the rectangular patio, use the equations for perimeter and area and solve for length and width.
Explanation:To find the dimensions of the rectangular patio, we can use the given information about its perimeter and area. Let's assume the length of the patio is L and the width is W.
The perimeter is given as 34 meters, which is equal to 2L + 2W. So, we have the equation 2L + 2W = 34.
The area is given as 70 square meters, which is equal to L * W. So, we have the equation L * W = 70.
We can use these equations to solve for L and W using substitution or elimination method.

Which of the binomials below is a factor of this trinomial?
x2 + 13x + 42
A. x - 7
B. x + 7
C. x + 84
D. x2 + 12
The trinomial x^2 + 13x + 42 factors into (x + 7)(x + 6), making x + 7, which is option B, the correct binomial factor of the trinomial.
To determine which binomial is a factor of the trinomial x2 + 13x + 42, we need to factor the trinomial. To factor the trinomial, we are looking for two numbers that multiply to give us the constant term (42) and add to give us the linear coefficient (13). These two numbers are 7 and 6 because 7 * 6 = 42 and 7 + 6 = 13.
So, we can factor the trinomial as (x + 7)(x + 6). Thus, the binomial that is a factor of x2 + 13x + 42 is x + 7, which is option B.

The coming head in the fourth time is independent of the coming head in the first three times thus the probability of coming head in the fourth time is 1/2.
What is probability?Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
In our daily time, there are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.
As per the given,
In the first three attempts coming head in the first three times.
In the fourth attempt, the probability will be independent of the first three events.
Thus, the probability of coming ahead in the fourth time will be as,
Number of desire output/number of total output
