There is one more quiz this quarter. Quiz Score 1 2 3 4 18 at least 19 17 20 What is the mininum score Carlos can earn on the final quiz to earn at least a 90% average? points
Answers
Carlos needs to earn at least 16 points on the final quiz to earn at least a 90% average.
We have,
Let's start by finding the total number of points that Carlos can earn in the class:
Total points
= 5 quizzes x 20 points per quiz
= 100 points
If Carlos needs an average of 90% or greater, that means he needs to earn at least 90 points out of 100.
Total points earned.
= 18 + 19 + 17 + 20
= 74 points
To find the minimum score Carlos needs on the final quiz, we can set up an inequality:
(74 + x) / 5 ≥ 0.9
where x is the score on the final quiz.
Simplifying this inequality.
74 + x ≥ 90
x ≥ 16
Therefore,
Carlos needs to earn at least 16 points on the final quiz to earn at least a 90% average.

a bakery has six bags of flour. they are are asked to make four loaves of bread
the first two loaves each require two bags and quarter of another bag
the next loaf requires one bag and two thirds of another bag
the final loaf requires a half bags of flour
write a calculation,using brackets ,to work out how much flour the bakery will have left the bakery will have left after making these loaves
Answers
The bakery is short on half a bag of flour.This problem can be solved using fractions . So, first loaf of bread requires 2bags of flour and a quarter which can be written as 2\(\frac{1}{4}\)second loaf of bread also requires the same amount which is 2\(\frac{1}{4}\)
the third loaf of bread requires one bag and two third of another bag which can be written as 1\(\frac{2}{3}\)
And the final loaf of bread requires half bag of flour which is \(\frac{1}{2}\)
the total requirement of flour for making the four loaves of bread is
= 2\(\frac{1}{4}\) + 2\(\frac{1}{4}\)+ 1\(\frac{2}{3}\)+\(\frac{1}{2}\)
=\(\frac{9}{4}\) +\(\frac{9}{4}\) + \(\frac{5}{3}\) + \(\frac{1}{2}\)
= \(\frac{27}{12}\)+ \(\frac{27}{12}\) +\(\frac{20}{12}\) +\(\frac{6}{12}\)
= \(\frac{80}{12}\)
To work out how much flour the bakery will have left after making these loaves we need to reduce the total requirement with total flour we have = 6 -\(\frac{80}{12}\)
=\(\frac{72}{12}\) - \(\frac{80}{12}\)
=- \(\frac{6}{12}\) or- \(\frac{1}{2}\)
therefore the bakery is short on half a bag of flour

Both students identified the function to be represented by the, d=13h-75, where d is the amount of money in a checking account and h is the number of hours worked. Hunter explained the equation represented an original amount of $75 that decreased $13 for every hour. Christopher disagreed. He interpreted the equation as a person who was in debt $75 earned $13 every hour.
Answers
Using linear function concepts, it is found that Christopher is correct.
What is a linear function?A linear function is modeled by:
\(y = mx + b\)
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can be interpreted as the initial value.In this problem, the function is:
\(d = 13h - 75\)
Considering the description of the output d as the amount of money in a checking account and of the input h as the number of hours worked, we have that:
For each hour worked, the person earns $13.Considering taxes, the person starts at a debt of $75.Hence, Christopher is correct.

A. False. The first part of the statement is true, but the second part is not. The sample mean is not always equal to the population mean. The sample mean will vary (it's a random variable).
B. True. The larger the sample, the better the estimate. Ideally we would take a census, but that is often too costly. The next best thing is to select a sample that is of the proper size.
C. True. Consider a normal distribution with mean mu and standard deviation sigma. The distribution of sample means, aka xbar distribution, will have mean mu and standard deviation sigma/sqrt(n), where n is the sample size. We see that sigma/sqrt(n) is smaller than sigma. This tells the xbar distribution is much taller and more narrow compared to the normal distribution.

184 196 185 174 186 197 170

b) Use your stem-and-leaf plot to determine the median and the mode.
C)Calculate the mean of the data.
Answers
```
15 | 1
17 | 0 0 1 4
18 | 2 4 5 6 6
19 | 3 4 5 6 7 9
```
b) To find the median, we need to put the data in order from least to greatest:
```
151 170 170 171 174 178 179 182 184 185 186 186 186 193 194 195 196 197 199 219
```
There are 20 numbers in the data set, so the median is the average of the 10th and 11th numbers:
```
Median = (185 + 186) / 2 = 185.5
```
To find the mode, we look for the most common value in the data set. In this case, the stem-and-leaf plot shows that there are two modes: 186 and 170.
c) To calculate the mean, we add up all the numbers and divide by the total number of numbers:
```
Mean = (219 + 151 + 199 + 186 + 170 + 186 + 194 + 184 + 196 + 185 + 174 + 186 + 197 + 170 + 178 + 179 + 182 + 193 + 195 + 171) / 20
Mean = 1849 / 20
Mean = 92.45
```
Therefore, the mean of the data is 92.45.
A pyramid has a rectangular base of length (3x + 1)cm and width xcm.
It also has a perpendicular height of 12 cm.
The volume of the pyramid is 96 cm³.
Given that the volume of a pyramid is one third of the area of the base
multiplied by the perpendicular height, find the dimensions of the base
of the pyramid.
Optional working
width: Answer
length: Answer

cm
Answers
The width of the rectangular base of the pyramid is approximately 3.74 cm, and the length is approximately 11.22 cm (since it is given as 3x+1).
What is base of a pyramid?The base of a pyramid can be any polygon, such as a square or a triangle, but the height must always be measured perpendicular to the base.
Define the term dimensions?Dimensions refer to the number of coordinates needed to specify the location of an object in space.
Based on the given information, we can set up an equation to solve for x, which is the width of the rectangular base of the pyramid:
Volume of pyramid = 1/3 × base area ×height
96 = 1/3 ×(3x+1) × x ×12
Simplifying the equation:
96 = 4x² + (4/3)x
Multiplying both sides by 3 to eliminate the fraction:
288 = 12x² + 4x
Rearranging the equation into a quadratic form:
12x² + 4x - 288 = 0
Dividing both sides by 4 to simplify the equation:
3x² + x - 72 = 0
We can then use the quadratic formula to solve for x:
x = (-b ± \(\sqrt{(b^2-4ac)}/2a\)
where a = 3, b = 1, and c = -72.
Plugging in the values:
x=(-1±\(\sqrt{1^2-4(3)(-72)} /2(3)\))
x=(-1±\(\sqrt{1+864} /6\))
x = (-1 ±\(\sqrt{865} /6\) )
Since the width of the base cannot be negative, we take the positive solution:
x = (-1 + √(865) / 6
Therefore, the width of the rectangular base of the pyramid is approximately 3.74 cm, and the length is approximately 11.22 cm (since it is given as 3x+1).

Using the Law of Sines, we get an angle of 2.41 degrees and no triangles are produced.
Option (C) is the correct one.
Given, Two sides and an angle are given below.
we have to determine whether the given information results in one triangle, two triangles, or no triangle at all.
If b = 5, c = 6 and B = 20 degrees in the triangle.
On using the concept of Laws of Sines, we get
sinA/a = sinB/b = sinC/c
sin 20°/5 = sin C/6
0.34/5 = sin C/6
0.007 = sin C/6
sin C = 0.042
C = 2.41
So, the angle C be 2.41 degrees.
which implies that no triangle can be formed or produced with the given data of the triangle.
