I assume you mean the mixed number 1 + 7/9.
As an improper fraction, we have
1 7/9 = 1 + 7/9 = 9/9 + 7/9 = (9 + 7)/9 = 16/9
Then the square root of this is
√(1 7/9) = √(16/9) = √(4²/3²) = √((4/3)²) = 4/3
The answer for 7. and 6. is compare and contrast :)
<span>the sum of 5 and 2x : 5 + 2x
You can't add this because they are not like terms

Answer:
Either 3/80 grams or 0.0385 grams
Step-by-step explanation:
1 tablet = 1/40 of a gram
1/40 of a gram = 1 ÷ 40 = 0.025 grams
1 tablet = 0.025 grams
1.5 tablets = x
1/1.5 = 0.025 / x Cross multiply
x*1 = 0.025 * 1.5 Combine the factors
x = 0.0375 grams Convert to a fraction
0.0375 = 3/80
Answer: 1.460
Step-by-step explanation:
Given : Researchers report that on average freshman who live on campus gain 15 pounds during their first year in college.
Let 
represents the population mean .
Then, the set of hypothesis will be:-
We assume that this is normal distribution.
Sample size : n = 10, which is a small sample (n<30) ,s o we use t-test.
Sample mean : 
Standard deviation : 
The test statistic for population mean for small sample is given by :-
Hence , the value of test statistic = 1.460
