Answer:
a. 146 ≤ 9c + 10
Explanation:
Step 1 - Find Out What Symbol We Will Be Using
Natalies budget is $146. This means she can spend less than or exactly $146 on yoga training. So, we will be using the less than or equal to symbol. It looks like this: ≤.
Step 2 - Eliminate Incorrect Options
Now that we know the symbol will look like ≤, we can eliminate options d and b.
Step 3 - Find Out Which Is The Dependent Variable
Natalie is going to buy a yoga mat which only costs $10. She is also going to join yoga classes which costs $9 per class. Since, the total cost of yoga classes depends on how many classes she takes, this is the dependent variable.
Step 4 - Write The Equation Using The Information Gathered
146 ≤ 9c + 10
Answer:
H0: p = 0.1 and Ha: p > 0.1
Step-by-step explanation:
At the null hypothesis, we test if the mean or proportion is equal to a certain value.
At the alternate hypothesis, we test if the mean or proportion is less than, more than, or different of the value tested at the null hypothesis.
A quality control inspector wants to determine if more than 10% of all shells contain just one peanut.
The value of 10% = 0.1 is tested, which means that the null hypothesis is 
Test if it is more than 10% = 0.1, so the alternate hypothesis is: 
Answer:
The total weight change for the eight women was -24.
Step-by-step explanation:
In order to find the answer, you have to consider that average is calculated by dividing the total weight change by the number of women and you know that the average was they lost 3 pounds and there were 8 women:
Average= total weight change/number of women
-3=total weight change/8
total weight change=-3*8
total weight change=-24
According to this, the answer is that the total weight change for the eight women was -24.
3 n
- = -
4 10
cross multiply to get 4n=(3)(10)
multiply 3 and 10. 4n/4 = 30/4
n = 7.5
