Answer:
The value of x would be 15
Explanation:
10/x = 2/3
Cross multiply:
10 · 3 = x · 2
30 = 2x
30 ÷ 2 = x
15 = x
Answer:
the E is the same as the circles
Step-by-step explanation:
To factor the expression you need to find the greatest common factor of the terms. The greatest common factor (GCF) is the highest number that will be into both terms. Since there's nothing that will fit into both x and y, you'll only need to find the GCF of the coefficients.
16x + 40y To start, list the factors of both numbers
16: 1, 2, 4, 8, 16
40, 1, 2, 4, 5, 8, 10, 20, 40
You can see that 8 is the highest number that will go into 16 and 40. So, you can pull the 8 out of the expression.
8(2x + 5y)
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.
