What is the correct equation for this word problem?
Sophia brought some almonds from the store. She handed the cashier $15 and received $5 in change.
A. 15/a = 5
B. 15 + a = 5
C. 15a = 15
D. 15 - a = 5
Answers
Answer: 15-a=5
Step-by-step explanation:
15 is the amount she paid in total. 15 pounds - 5 pounds = 10 pounds
so the original price was 10 pound.
Answer:
\( \sf \: d) \: 15 - a = 5\)
Step-by-step explanation:
Given information,
→ Sophia brought some almonds.
→ She paid $15 and received $5.
Now we have to,
→ Find the required equation.
Let us assume that,
→ a = Cost of the almonds
The equation will be,
→ 15 - a = 5
=> As she is received $5 as change.
Then the cost of almonds is,
→ 15 - a = 5
→ -a = 5 - 15
→ -a = -10
→ [ a = $10 ]
Hence, the option (d) is correct.
Suppose your marketing colleague used a known population mean and standard deviation to compute the standard error as 45.1 for samples of a particular size. You don't know the particular sample size but your colleague told you that the sample size is greater than 80. Your boss asks what the standard error would be if you double the sample size. What is the standard error for the new sample size
Answers
If the standard error for samples of a particular size (which is greater than 80) is calculated as 45.1, and you want to determine the standard error for a doubled sample size, we can use the following relationship:
Standard Error for the new sample size = Standard Error for the original sample size / √(New Sample Size / Original Sample Size)
Let's denote the original sample size as n and the standard error for the original sample size as SE_original.
SE_original = 45.1 (given)
Let's assume the new sample size is 2n (double the original sample size). The standard error for the new sample size, denoted as SE_new, can be calculated as follows:
SE_new = SE_original / √(2n / n)
SE_new = SE_original / √2
Substituting the given value of SE_original:
SE_new = 45.1 / √2
Calculating this expression, the standard error for the new sample size is approximately 31.92 (rounded to two decimal places).
Therefore, if you double the sample size, the standard error would be approximately 31.92.

A hospital medical unit has 50 beds. During May, the unit provided 1,420 days of service. What was the average daily census for the medical unit in May
Answers
If a hospital medical unit has 50 beds and the unit provided 1,420 days of service, the average daily census for the medical unit in May is 28.4.
To find the average daily census for a medical unit in May, we divide the total number of days of service provided by the number of beds in the unit. Here's how we do it:
According to the question, Total number of beds = 50 and Total number of days of service = 1,420
Average daily census = Total number of days of service / Total number of beds
Average daily census = 1,420/50
Average daily census = 28.4
Therefore, the average daily census for the medical unit in May is 28.4.

What is the area, in square centimeters, of the shaded part of the rectangle shown below
Answers
Answer:100 cm
Step-by-step explanation: first, you would find the area of the whole rectangle.
L x W = A

Take 40 and subtract it from the area of the whole rectangle
140-40=100
the indexed variables (members) of an array must be integers. true or false
Answers
It is true that the indexed variables (members) of an array must be integers.
The indexed variables or members of an array must be integers. This is because arrays are data structures that store elements in a contiguous block of memory, and each element is accessed using an index. Indexing allows us to uniquely identify and retrieve specific elements within the array. In most programming languages, including C, C++, Java, and Python, array indices are integers and must be whole numbers (positive or negative) without any fractions or decimals. Attempting to use non-integer values as indices would result in a compilation error or unexpected behavior.

a basket of fruits contains 5 apples and 3 pears. sharon took two fruits at random. what is the probability that both fruits are apples? write your answer in the simplest form of fraction
Answers
The probability that Sharon randomly selects two apples from the basket of fruits, given that there are 5 apples and 3 pears, can be expressed as a fraction.
To find the probability, we need to consider the total number of possible outcomes and the number of favorable outcomes.
The total number of possible outcomes is the number of ways Sharon can select any two fruits from the basket, which can be calculated using combinations. In this case, there are 8 fruits in total, so the total number of possible outcomes is C(8, 2) = 28.
The number of favorable outcomes is the number of ways Sharon can select two apples from the five available in the basket, which is C(5, 2) = 10.
Therefore, the probability that both fruits Sharon selects are apples is 10/28, which can be simplified to 5/14.

the graph of which function passes through (0,4) and has a minimum value at ?
Answers
The graph of f(x) = sin(x) + 4 function passes through (0,4) and has a minimum value.
What is function?
A function is a rule or relationship that assigns a unique output value to each input value.A function is typically denoted by a symbol, such as f(x) or g(x), where "x" represents the input value.
sin(x) has a point at (0,0) so that's not right.
sin(x)+4 has (0,4) as a point and a minimum at (3*pi/2+2*pi*n,3) where n is some integer. if we have n = 0 then it becomes (3*pi/2, 3).
Therefore the answer is f(x)=sin(x)+4
cos(x) + 3 has a point at (0,4) then minimums at (pi+2*pi*n, 2)
the y coordinate is wrong.
-3sin(x) has a point at (0,0) so that's wrong
4cos(x) has a point at (0,4) then minimums at (pi+2*pi*n, -4) which again has the wrong y value so this is wrong.

We have two equations :
x=y-9
5x+2y = 11
We just have to plug the value of x in the second equation to find y :
5(y-9) + 2y = 11
5y - 45 + 2y = 11
7y - 45 = 11
7y = 11 + 45
7y = 56
y = 56/7 = 8
Finally, since x = y -9
x = 8-9 = -1

what is the probability that a random 9-digit social security number has at least one repeated digit
Answers
The answer is 99.63% using probability.
What is probability?
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.
So the probability that 9-digit social security no number repeated digit is
10!=996371200
\(\frac{996371200}{1000000000}=\frac{155683}{156250}=0.9963712\)
So chance that at least one number is repeated =
1-\(\frac{10!}{10^{9}}=\frac{155683}{156250}=0.99637121\)
=0.9963712
Hence the probability is 99.63%

sally and joe go camping for the fourth of july.they will pitch a tent that has the shape of a trapezoid.see a diagram of the front of their tent below
Answers
The fact that Sally and Joe are pitching a tent in the shape of a trapezoid for their Fourth of July camping trip is an interesting choice.
What is diagram?Diagrams are visual representations of ideas, concepts, processes, or objects. They are often used to illustrate and explain complex systems or ideas. Diagrams are a versatile tool that can be used in a variety of fields, from engineering to science and even in business. Diagrams can help to explain complex structures and relationships, provide visual support for a presentation, or quickly convey information in a concise format. They can also be used to compare and contrast different concepts or processes. Diagrams are an effective way to communicate ideas in a visual form.
Having a trapezoid-shaped tent provides numerous advantages over other tent shapes.
One major benefit of a trapezoid tent is its stability. The tent is designed with two sides that have sloping walls, which can deflect wind more effectively than a traditional rectangular tent. This allows the tent to remain standing even in high winds, making it a great choice for camping in areas with potentially inclement weather.
The trapezoid design also provides more interior space than a traditional tent. The sloping walls create a greater area for sleeping and storage, which can make for a much more comfortable camping experience.
Additionally, the trapezoid shape allows for more flexibility when it comes to where the tent can be pitched. The tent can be set up on uneven ground, which allows Sally and Joe to find the perfect spot to camp without needing to level the ground first.
Overall, a trapezoid-shaped tent makes a great choice for Sally and Joe’s Fourth of July camping trip. Its stability, extra interior space, and flexibility make it an ideal choice for camping in a variety of conditions.
