Step-by-step explanation:
Collect all like terms and Calculate
-10x-7x= -17x
20-54= -34
Divide
-17x < -34
x>2
This should be your answer
Answer:
76.8
Step-by-step explanation:
1. We assume, that the number 31.25 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 31.25, so we can write it down as 100%=31.25.
4. We know, that x% equals 24 of the output value, so we can write it down as x%=24.
5. Now we have two simple equations:
1) 100%=31.25
2) x%=24
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=31.25/24
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 24 is what percent of 31.25
100%/x%=31.25/24
(100/x)*x=(31.25/24)*x - we multiply both sides of the equation by x
100=1.3020833333333*x - we divide both sides of the equation by (1.3020833333333) to get x
100/1.3020833333333=x
76.8=x
x=76.8
now we have:
24 is 76.8% of 31.25
Answer: Screams internally
Step-by-step explanation:
Answer:
We conclude that he used a paired two-sample t-test.
Step-by-step explanation:
We know that the student measuring how gasoline prices change records the cost of gas at 10 randomly selected stations in her hometown. One week later, she records the price again at the same 10 stations.
We conclude that he used a paired two-sample t-test.
Because at each gas station, the student measured the price of gas twice.
