A bakery sold 154 mocha cupcakes in a day, which was 35% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?
Answers
Answer:
440
Step-by-step explanation:
If we have the information that 154 mocha cupcakes = 35% of the total cupcakes sold on a certain day, then to find the total number of cupcakes old that day, we can set up a simple proportion.
So, with x = the unknown number of total cupcakes
35% = 154 / x
==>
35 / 100 = 154 / x
We can use cross-multiplication to simplify to ==>
35x = 15,400
Now we divide both sides by 35 to isolate our variable ==>
x = 440
So, the total number of cupcakes sold that day (100%) was 440 cupcakes

Answers
Answer:
b must be positive
Step-by-step explanation:
if a is less than -1
that means to get smaller numbers
b needs to be positive
so that when a is multiplied by b you would have
numbers that are more negative
Answer:
b > 1
Step-by-step explanation:
Given:
a < -1 ab < aSubstituting a = -1 into ab < a
⇒ (-1)b < -1
⇒ -b < -1
⇒ b > 1
If a < -1 then a is negative. If ab < a then ab is also negative.
In order for ab to be negative (when a is negative) b must be positive.
For ab < a then b > 1.
Proof
If b = 0.5 and a = -1.5 then ab = -0.75
As -0.75 > -1.5 then ab > a so this cannot be true.
If b = 1.5 and a = -1.5 then ab = -2.25
As -2.25 < -1.5 then ab < a so this is true.
Therefore b > 1

27: 7's
29: 8's
15: 9's
Now to find the answer, we must know the total amount of results, which I found to be 250. We also need to know the total amount of non-participants there are, which is 99. So if we take 99 and divide it by 250 (99/250); we get 0.396. Although this isn't the exact answer, it is the closest.
To further prove that this should be right, Yuri found 60% of students to participate, which leaves around 40% left to not participate. So this should be right.

Sharon has a soap and water mixture that is 36% soap. How many liters of water must
Sharon add to 5 liters of this mixture to make a solution that is 12% soap?
Answers
The volume of water that Sharon must add to the 5 liters mixture to make a solution that is 12% soap is 10 liters
Dilution lawFrom the question, we are to determine how many liters of water must Sharon add to 12% soap solution
Using the dilution law formula,
C₁V₁ = C₂V₂
Where C₁ is the initial concentration
V₁ is the initial volume
C₂ is the final concentration
and V₂ is the final volume
From the given information,
C₁ = 36%
V₁ = 5 liters
C₂ = 12%
V₂ = ?
Putting the parameters into the equation, we get
36 × 5 = 12 × V₂
180 = 12V₂
∴ V₂ = 180 / 12
V₂ = 15 liters
This means the final volume of the solution will be 15 liters.
Volume of water that must be added = V₂ - V₁
Volume of water that must be added = 15 liter - 5 liters
Volume of water that must be added = 10 liters
Hence, the volume of water that Sharon must add to the 5 liters mixture to make a solution that is 12% soap is 10 liters.

Step-by-step explanation:
This is because, in order to find the range you need to set the order from lowest to highest and subtract the lowest from the highest. So in this case the lowest would be 117 and the highest would be 174. So when you subtract them you get 57.
Answer:
1) Range = 57
2) Range = 12
3) Median = 88, First Quartile = 84, Third Quartile = 92, Interquartile = 8
4) Median = 81.5, Median of lower half = 67, Median of upper half = 92,
Describe the spead of the data = ______

5) a. Range = 172 points, Interquartile Range = 42 points
b. Outlier = 193, Range without the Outlier = 101 points, Interquartile Range without the Outlier = 48.5 points
c. The outlier affected the __________ more.
*We cannot see the drop-down answer choices here, so we cannot answer this part of the question. Sorry.
Good Luck! I hope this helps!
Step-by-step explanation:
1) Find the range of the data.
133, 117, 152, 127, 168, 146, 174.
First, put the numbers in ascending order:
117, 127, 133, 146, 152, 168, 174
To find the range, subtract the smallest number from the largest number.
174 - 117 = 57
So, the range is 57.
2) Find the range of the data.
26, 21, 27, 33, 24, 29
First, put the numbers in ascending order.
21, 24, 26, 27, 29, 33
To find the range, subtract the smallest number from the largest number.
33 - 21 = 12
So, the range is 12.
3) Find the median, first quartie, third quartile, and interquartile range of the data. 84, 75, 90, 87, 99, 91, 85, 88, 76, 92, 94
First, put the numbers in ascending order.
75, 76, 84, 85, 87, 88, 90, 91, 92, 94, 99
The median is the value in the middle, so in this case, it is 88.
To find the first quartie, third quartile, and interquartile, we must split the numbers into quarters.
75 76 84 85 87 88 90 91 92 94 99
The first quartile is 84.
The third quartile 92.
The interquartile is the first quartile subtracted from the third quartile, so
92 - 84 = 8.
4) Use grid paper to find the median of the data. Then find the median of the lower half and the median of the upper half of the data.
82, 62, 95, 81, 89, 51, 72, 56, 97, 98, 79, 85
First, put the numbers in ascending order.
51, 56, 62, 72, 79, 81, 82, 85, 89, 95, 97, 98
Find the median which is the middle of the values.
51 56 62 72 79 81 82 85 89 95 97 98
In this case, it is between 81 and 82, so we find 81+82 / 2 = 81.5.
The median is 81.5.
The median of the lower half of the data is the value in the middle of the first 6 of the 12 numbers. 51 56 62 72 79 81
We need to find 62+72 / 2 = 134 /2 = 67, so the median of the lower half of the data is 67.
The median of the upper half of the data is the value in the middle of the last 6 of the 12 numbers. 82 85 89 95 97 98
We need to find 89+95 / 2 = 184 / 2 = 92, so the median of the upper half of the data is 92.
Describe the spread of the data.
The data are ___________ . (We cannot see the drop-down options, so cannot answer this part of the question. Sorry.)
5) The table shows the number of points scored by players on a basketball team. 21 53 74 82 84 93 103 108 116 122 193
a. Find the range and interquartile range of the data.
To find the range, subtract the smallest number from the largest number.
193 - 21 = 172
The range is 172 points.
To find the interquartile range, we must split the numbers into quarters.
21 53 74 82 84 93 103 108 116 122 193
The first quartile is 74.
The third quartile 116.
The interquartile is the first quartile subtracted from the third quartile, so
116 - 74 = 42.
The interquartile range is 42 points.
b. Use the interquartile range to identify the outlier(s) in the data set.
Find the range and the interquartile range of the data set without the outlier(s).
21 53 74 82 84 93 103 108 116 122 193
Per Wikipedia, "In statistics, an outlier is a data point that differs significantly from other observations."
Per statology.org, "One popular method is to declare an observation to be an outlier if it has a value 1.5 times greater than the interquartile (IQR) or 1.5 times less than the IQR."
From statology. org:
(Note: Q1 = first quartile, Q3 = third quartile, IQR = interquartile)
The lower limit is calculated as:
Lower limit = Q1 – 1.5 * IQR = 74 – 1.5 * 42 = 74 - 63 = 9.
The lower limit of outliers is 9 points.
And the upper limited is calculated as:
Upper limit = Q3 + 1.5 * IQR = 116 + 1.5 * 42 = 116 + 63 = 179.
The upper limit of outliers is 179 points.
The outlier is 193 points.
To find the range without the outlier, subtract the smallest number from the largest number.
21 53 74 82 84 93 103 108 116 122
122 - 21 = 101 points
The range without the outlier is 101 points.
To find the interquartile range wthout the outlier, we must split the numbers into quarters.
21 53 74 82 84 93 103 108 116 122
The first quartile is 53+74 / 2 = 127 / 2 = 63.5.
The third quartile 108+116 / 2 = 224 / 2 = 112.
The interquartile is the first quartile subtracted from the third quartile, so
112 - 63.5 = 48.5.
The interquartile range without the outlier is 48.5 points.
c. Which measure did the outlier affect more?
The outlier affected __________ more. (We cannot see the drop-down options, so cannot answer this part of the question. Sorry.)

Choose 1 answer:
Answers
Answer:
0.02< P-value<0.04
Step-by-step explanation:
Since this P-value is less than the usual significance level of 0.05, we would reject the null hypothesis and conclude that there is evidence of a difference between the true population mean and 36 at the 0.05 level of significance.
What is hypothesis testing?Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.
It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.
We have,
To find the P-value for Jasper's test, we need to use the t-distribution with degrees of freedom (df) equal to the sample size minus one,
which is 16-1=15 in this case.
Using a t-table or a calculator, we can find that the two-tailed P-value for t=2.4 with df=15 is approximately 0.029.
This means that if the null hypothesis is true (i.e., if the true population mean is 36), the probability of observing a sample mean as extreme as or more extreme than the one obtained by Jasper is 0.029.
Thus,
Since this P-value is less than the usual significance level of 0.05, we would reject the null hypothesis and conclude that there is evidence of a difference between the true population mean and 36 at the 0.05 level of significance.
