In a parking lot of 240 red and blue cars, the ratio of red cars to blue cars is 3:5. How many red cars are in the parking lot?
Answers
240 red and blue cars
3:5 ratio of red cars to blue cars
3 + 5 = 8
red cars: 3/8 * 240 = 90
blue cars: 5/8 * 240 = 150
ratio of red cars to blue cars: 90:150
simplify:
90 ÷ 30 = 3
150 ÷ 30 = 5
Thus: 90:150 = 3:5
Answer:
90, because 3/8 of the cars are red

In march, a customer spent $8.55 at an office-supply store for some 12-packs of pens. At that time, the store was selling packages of one dozen pens for $1.35. Any customer who bought more than 4 packages, received a discount of $0.30 on the price of each package in excess of 4 packages. In september, the same customer went back to the store to buy the same number of pens. By then, the price per 12-pack of pens had been raised to $1.50 each, with the same discount for more than 4 packages. How much more did the customer have to pay in September than in March?

Answers
Answer:
the interquartile range of the data is:
4
Step-by-step explanation:
We are given a data set as:
0, 2, 4, 0, 2, 3, 2, 8, 6
On arranging the data in the ascending i.e. increasing order is given by:
0 0 2 2 2 3 4 6 8
The minimum value of data set=0
Maximum value of data set is: 8
Range of data set= Maximum value-Minimum value
i.e. Range= 8-0
i.e. Range= 8
Also, Median of set is the central tendency of the data and is given by:
Median= 2
Lower set of data is:
0 0 2 2
Hence, The median of lower set of data is the lower quartile or first quartile.
i.e.
Hence,
Hence, Lower quartile=1
Similarly upper set of data is:
3 4 6 8
Hence, The median of upper set of data is the upper quartile or third quartile.
i.e.
Hence,
Hence, Upper quartile=5
Hence, the interquartile range(IQR) is given by:
IQR=Upper quartile-Lower quartile
IQR=5-1
IQR=4

Answer:
The smaller number is 18
Step-by-step explanation:
Let the numbers be and
where x is the smaller number;
.
The sum of the numbers is 100.
The sum of 8 and the larger number is equal to 5 times the smaller number.
Put equation (2) into equation (1).
Answer:
The smaller number is 18.
Step-by-step explanation:
We have given that
The sum of two numbers is 100. The sum of 8 and the larger number is equal to 5 times the smaller number.
Let x and y are two numbers.
Let y is the larger number.
x+y = 100 eq(1)
y+8 = 5x eq(2)
From eq(1), we have
y = 100-x
Putting above eq(3) into eq(2), we have
100-x+8 = 5x
108 = 5x+x
108 = 6x
x = 108/6
x = 18
Hence, the smaller number is 18.
