Answer:
ranges from 2890 miles to 5780 miles.
Step-by-step explanation:
Let us call
the number of miles the car travels, and
the number of gallons of gas that are used, then we have the relationship
<em>(this says the car travels 17 miles for each gallon of gas).</em>
Now, when
, we have


and when
, we have


So, when
goes from 170 to 340,
goes from
to
.
Therefore, when
ranges from 170 to 340 gallons, the distance traveled ranges from 2890 to 5780 miles.
Answer:
As 2.551 < 3.84 therefore we reject H0.
As 44.803 > 4.46 so we accept null hypothesis.
Step-by-step explanation:
The answer is attached.
There are three judges so v1 = 3-1= 2 and v2 = (4*2)= 8
There are five gymnasts so v1 = 5-1= 4 and v2= (4*2)= 8
For alpha = 0.05 we find the value of F1 and F2 from the table.
Answer:
The area of the bulletin board is 30 square foot.
Step-by-step explanation:
A bulletin board can be covered completely by 30 square pieces of paper without any gaps or overlaps.
If each piece of paper has side length of 1 foot so the area of each paper is 1 ft x 1 ft = 1 square foot.
There are 30 pieces of paper needed to completely cover the bulletin board, so 30 pcs of paper with an area of 1 square foot is equal to 30 square feet. The area of the bulletin board is 30 square foot.
Answer: 
Step-by-step explanation:
You know that:
- 2/5 of the spice mixture was oregano.
- 1/3 of the spice mixture was basil.
Then, to find the fraction of the total amount of spice mixture that was oregano and basil, you must add both fractions, as following:
- Find the least common multiply of the denominators:

- Divide the LCM by each original denominator and multiply the result by each numerator.
- Make the addition.
Then, the result is:

Answer:
The size of Isabella's pool is 220 liters.
Step-by-step explanation:
Let the size of Isabella's pool be
liters,
be the rate of fill,
be the time of fill and
be the volume of water filled in the pool.
As the rate of fill is constant,
Therefore, volume of water filled in the pool can be given as,

Volume of water left is given as 
From the table,
Volume of water left after
minutes is 184 liters.
So,
-------- 1
Volume of water left after
minutes is 4 liters.
So,
------------2
Multiply equation 1 by 6 and equation 2 by -1, we get

Now, we add the above equations, we get

Therefore, the size of Isabella's pool is 220 liters.
