Answer:
a
Step-by-step explanation:
1.
x+7=0
x=-7
2.
2x-3=0
2x=3
x=3/2
You just need to find the x for each when it equals to zero
Brillianst please!
Well, first you'll need to turn all of the fractions into decimals. You do this by diving the numbers by eachother.
So,
7/12 = .58333
3/4 = .75
2/3 = .66666666......7
5/6 = .83333333
2/4 = .5
Now, you have to figure out which decimal is smaller then .58333. By, looking at these decimals, you'll see that 2/4 is less then 7/12.
I hope this helps!
<span>To solve for any value in an equation, you must first isolate the variable. n=6 x 35 + 4 can be solved easily by finding the answer to 6 x 35 + 4. You must first use the rule of PEMDAS - this stands for parenthesis, exponents, multiplication, division, addition, subtraction. So, in this equation you would do 6 x 35, find the answer which is 210 then add 4. So the final answer is 214 - n = 214.</span>
Answer:
Null hypothesis:
Alternative hypothesis:
Or equivalently :
Null hypothesis:
Alternative hypothesis:
Step-by-step explanation:
Data given and notation
represent the sample mean
represent the sample standard deviation for the sample
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to check if the true mean is lower than 10.1 ft (alternative hypothesis) , then the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Or equivalently :
Null hypothesis:
Alternative hypothesis:
