Answer:
Step-by-step explanation:
7√x-9√x+10√2+√2 = √x ( 7 - 9) +√2 ( 10+1) = - 2√x + 11√2
Answer:
Step-by-step explanation:
abs ( -2(5-(-1)) / 3 )
= abs ( -2(5+1) / 3 )
= abs ( -2(6) /3)
= abs (-12 /3)
= 4
(3(-1) -- 1) /2
= (-3 -1) /2
= -4 / 2
= -2
since 4 is greater than - 2 this is inequality is true
1/16+ 1/12
= 3/48+ 4/48 (common denominator)
= 7/48
The final answer is 7/48~
The sum is 7. 012 × 10^-8. Option C
<h3>What is index form?</h3>
Index form is defined as the power or exponent which is raised to a number or a variable.
For example, in number 5^2, 2 is the index of 5.
Indices is the plural form of index.
To add index forms, we need to note the following:
- Both the exponents and variables should be same
- Add the coefficients of the variables leaving the exponents unchanged.
- Only terms that have same variables and powers are added
Given:
(3.012 x 10−8) + (4 x 10−8)
3. 012 + 4 (10^-8)
7. 012 × 10^-8
Thus, the sum is 7. 012 × 10^-8. Option C

Answer:
Sample mean = 6.25 hours per night.
Population mean = 5.5 hrs of sleep each night.
Step-by-step explanation:
A sample mean is the mean of the sample collected. The 25 students surveyed by the student is the sample. The average sleep time derived from the sample is the sample mean.
A population mean is the mean of all the population. Here the population are college students. The population mean is the mean derived from studying the sleep duration of all the population - college students
