First, you'll have to find how much it costs for one bottle of juice.
Store A- 4/12= 0.33 So one bottle of juice costs 33 cents.
Store B- 6/18= 0.33 So one bottle of juice costs 33 cents.

Yes, the rates are equivalent because one bottle of juice costs the same from each store.

Store A = 12/4 = 3

Store B = 18/6 =3

S the rates are equivalent.

Coach Evans recorded the height, in inches of each player on his team. The results are shown.

Answer:

Step-by-step explanation:

Given:

Team heights (inches):

61, 57, 63, 62, 60, 64, 60, 62, 63

To find: IQRs (interquartile ranges) of the heights for the team

Solution:

A quartile divides the number of terms in the data into four more or less equal parts that is quarters.

For a set of data, a number for which 25% of the data is less than that number is known as the first quartile $(Q_1)$

For a set of data, a number for which 75% of the data is less than that number is known as the third quartile $(Q_3)$

Terms in arranged in ascending order:

$57,60,60,61,62,62,63,63,64$

Number of terms = 9

As number of terms is odd, exclude the middle term that is 62.

$Q_1$ is median of terms $57,60,60,61$

Number of terms (n) = 4

Median = $\frac{(\frac{n}{2})^{th} +(\frac{n}{2}+1)^{th} }{2} =\frac{2^{nd}+3^{rd}}{2} =\frac{60+60}{2}=\frac{120}{2}=60$

So, $Q_1=60$

So, 25% of the heights of a team is less than 60 inches

$Q_3$ is the median of terms $62,63,63,64$

Median = $\frac{(\frac{n}{2})^{th} +(\frac{n}{2}+1)^{th} }{2} =\frac{2^{nd}+3^{rd}}{2} =\frac{63+63}{2}=\frac{126}{2}=63$

So, $Q_3=63$

So, 75% of the heights of a team is less than 63 inches

Interquartile range = $Q_3-Q_1=63-60=3$

The interquartile range is a measure of variability on dividing a data set into quartiles.

The interquartile range is the range of the middle 50% of the terms in the data.

So, 3 is the range of the middle 50% of the heights of the students.

20% of the total – we need to take the value of 10% and double it: ...

15% of the total – we have to divide the value of 10% by 2 and then add the result to the value of 10%:

What is the simplified form of 3abc/abc, when abc does not equal zero? Explain using the properties of real numbers.

elixir [45]

3abc / abc
= 3 ( abc ) / abc
= 3

because the real numbers did not have zero. the real number are starting from positive 1 to positive infinity number.
If we suppose a = 1, b = 2, c = 3
abc / abc = 1.

I hope that i helped you :)

In letters (b) leave your answer in terms of the constants a, b, c and d

Ivan

I think you mean to find b in terms of the constants a, c and d.

(x + a ) / b - c = d

(x + a) / b = c + d

Cross multily:-

x + a = b(c + d)

b = (x + a) / (c + d)
