Step-by-step explanation:

You will want to simplify those numbers (reduce to lowest terms).

43% of 600 gallons of water is 258

Convert your percentage into a decimal:
$\frac{43}{100} = 0.43$

Multiply your decimal and 600:
$0.43 \times 600 = 258$

PLS HELP ME QUICK BRAINLIEST +15 POINTS!!!!!

Ipatiy [6.2K]

Answer:

3/4

Step-by-step explanation:

The mean of a data set is synonymous with the average. To find the mean, add up all the values in the data set and then divide by the number of elements.

From the table, there is 12 values. Thus, add up all the 12 values and then divide by 12:

$\bar x=\frac{(-3)+4+8+(-1)+(-4)+(-2)+0+2+5+2+(-3)+1}{12}$

Simplify:

$\bar x=\frac{9}{12}$

Reduce:

$\bar x=3/4$

Therefore, the mean of the data set is 3/4.

For the data set, this means that the average person guesses the temperature too high by about 3/4°F.

(Note: the symbol of x with a bar over it denotes the mean of a set)

The product of two consecutive odd integers is 782. What are the integers?

Alex Ar [27]

Call the smaller of the two odds = n

Call the next number in the sequence = n + 2

n*(n +2) = 782 Remove the brackets.

n^2 + 2n = 782 Subract 782 from both sides.

n^2 + 2n - 782 = 0 We are going to have to factor this.

Discussion

This problem can't be done the way it is written. The product of an odd integer with another odd integer is and odd integer. There are no exceptions to this. So you need to give a number that has two factors very near it's square root for this question to work.

For example, you could use 783, (which factors) instead of 782 .

Solve

n^2 + 2n - 783 = 0

(n + 29)(x - 27) = 0

Solution One

n - 27 = 0

n = 27

The two odd consecutive integers are 27 and 29.

Solution Two

n + 29 = 0

n = - 29

The two solution integers are -29 and - 27 Notice that - 29 is smaller than - 27.
