We can first convert 9.5 into fraction :
9.5= 9 1/2
Then we can use deduction to find out the answer:
9 1/2 - 6 1/3
=19/2 - 19/3
We change it to the same denominator:
=19×3/6 - 19×2/6
= 57/6 - 38/6
= 19/6
Therefore there are 19/6 or 3 1/6 gallons left in the tank.
Hope it helps!
Answer:
c=27/40 = 0.675
Step-by-step explanation:
the statement give us the expression:
1/8 +c= 4/5
we subtract the term "1/8" both sides:
we have:
1/8 -1/8+c= 4/5-1/8
c=4/5-1/8
c=(4*8)-(5*1)/(5*8)
c=(32-5)/(40)
c =27/40 = 0.675
Answer:
3x=4
Step-by-step explanation:
Answer:
2√(17) or about 8.2462 units.
Step-by-step explanation:
We want to determine the distance between the two points (-10, -7) and (-8, 1).
We can use the distance formula. Recall that:

Substitute and evaluate:

Hence, the distance between (-10, -7) and (-8, 1) is 2√(17) units or about 8.2462 units.
Answer:
The value of P-value is 0.0472.
Step-by-step explanation:
We are given that you take a simple random sample of 12 apartments in town A and calculate the average price of these apartments. You repeat this for 15 apartments in town B.
Let
= <u><em>true average price of apartments in town A</em></u>
= <u><em>true average price of apartments in town B</em></u>
So, Null Hypothesis,
:
Alternate Hypothesis,
:
The test statistics that have been used here is <u>two-sample t-test statistics</u>, i.e;
The test statistics given to us is 2.1
Now, the P-value of the test statistics is given by the following formula;
P-value = P(
> 2.1)
= P(
> 2.1) = 0.0236
In two-tailed test, P-value is calculated as = 2
0.0236 = <u>0.0472</u>
Hence, the value of the p-value is 0.0472.
