Answer:
11/2,5.5
Step-by-step explanation:
Step-by-step explanation:
Triangles RQP and RBC are congruent.
Letters R and P are the 1st and 3rd letters in RQP.
Letters R and C are the 1st and 3rd letters in RBC.
Hence line RP = line RC = line CR (D).
A whole number is a whole positive number (0, 1, 2,3 ,4....)
Integers are any whole number (negative or positive)
The answer is false
because an integer like - 4 is not a whole number
To solve this you can make a proportion where the matching sides will correspond to each other. It should look something like this:
Now you must cross multiply
10*42 = 15*x
420= 15x
To isolate x divide 15 to both sides
420/15 = 15x/15
28 = x
Hope this helped!

Complete question :
According to the National Association of Realtors, it took an average of three weeks to sell a home in 2017. Suppose data for the sale of 39 randomly selected homes sold in Greene County, Ohio, in 2017 showed a sample mean of 3.6 weeks with a sample standard deviation of 2 weeks. Conduct a hypothesis test to determine whether the number of weeks until a house sold in Greene County differed from the national average in 2017. Useα = 0.05for the level of significance, and state your conclusion
Answer:
H0 : μ = 3
H1 : μ ≠ 3
Test statistic = 1.897
Pvalue = 0.0653
fail to reject the Null ; Hence, we conclude that their is no significant to accept the claim that number I weeks taken to sell a house differs.
Step-by-step explanation:
Given :
Sample size, n = 40
Sample mean, x = 3.6
Population mean, μ = 3
Standard deviation, s = 2
The hypothesis :
H0 : μ = 3
H1 : μ ≠ 3
The test statistic :
(xbar - μ) ÷ (s/√n)
(3.6 - 3) / (2/√40)
0.6 / 0.3162277
Test statistic = 1.897
Using T test, we can obtain the Pvalue from the Test statistic value obtained :
df = n - 1; 40 - 1 = 39
Pvalue(1.897, 39) = 0.0653
Decison region :
If Pvalue ≤ α ; Reject the null, if otherwise fail to reject the Null.
α = 0.05
Pvalue > α ; We fail to reject the Null ; Hence, we conclude that their is no significant to accept the claim that number I weeks taken to sell a house differs.
