To write percent as decimal, divide it by 100
So 67/100 = 0.67
Answer:
a. x = 4 b. x = 7
Step-by-step explanation:
a. They are both congruent right angles because of the alternate exterior angles theorem
90-4 = 86
86/21 = 4
b. The angles are congruent because of the corresponding angles postulate
75+2 = 77
77/11 = 7
Hello!
1.
You have to add all the numbers up in the venn diagram to get how many people participated
18 + 11 + 24 + 8 + 7 + 1 + 17 = 86
The answer is 86 people

2.
To find how many people like country you add all the numbers in the country circle
8 + 7 + 1 + 17 = 33
The answer is 33 people
------------------------------------------------------------------------------------------------------
3.
To find how many people likes only country music you look at the number that is only in the country circle
The answer is 17 people
------------------------------------------------------------------------------------------------------
4.
To find how many people like rap and country you add the numbers that are in both of the circles
1 + 7 = 8
The answer is 8 people
------------------------------------------------------------------------------------------------------
5.
To find the amount of people that liked rap and country but not rock you look at the number in only the rap and country circle
The answer is 1 person
------------------------------------------------------------------------------------------------------
6.
To find how many people liked rock or rap you add all the numbers in those circles
18 + 7 + 11 + 24 = 60
The answer is 60 people

Answer:
11 cats
Step-by-step explanation:
I did trial and error.
I started with 16 cats and 17 dogs, so:
(16x$2.5) + (17x$4.5) = $116.5
The value is too low which means that they spent more money on the expensive side (i.e., dogs).
I ended up with 11 cats and 22 dogs, so:
(11x$2.5) + (22x$4.5) = $126.5
Answer:
See ecplanation below
Step-by-step explanation:
False.
On the Data analysis tool from excel we can conduct the following procedures:
Anova: Single Factor
Anova: Two factor with replication
Anova: Two factor without replication
Correlation
Covariance
Descriptive statistics
Exponential smoothing
F-test Two sample for Variances
Fourier analysis
Histogram
Moving Average
Random number generation
Rank and percentile
Regression
Sampling
t test: Paired two sample for means
t tes: Two sample assuming equal variances
t test: Two sample Assuming Unequal Variances
z test: Two sample for means
And as we can see we don't have an specific procedure just to obtain confidence interval for the difference of proportions. We need to remember that if we select a z test in excel, for example the output will contain the confidence associated to the parameter, but for this case is not too easy obtain a confidence interval for the difference of proportion like on a statistical software as (Minitab, R, SAS, etc) since all of these statistical softwares are elaborated in order to conduct all the possible statistical tests and confidence intervals for parameters of interest.
