Answer:

Range: 10 - 0 = 10

Mean: 0 + 3 + 5 + 12 + 16 + 9 + 10 = 55/7 = 7.8

Median: 6

Lower quartile: 3

Upper quartile: 8

Interquartile range: 8 - 3 = 5

¿cuales números naturales de dos cifras cumplen la condición de que su triple disminuido en 5, sea menor que su doble aumentado
stiks02 [169]

Answer: 10, 11 and 12.

Step-by-step explanation:

This translates to:

Find the natural numbers of two digits that fulfill the condition that when triple and decreased in 5, is less than the double increased in 8?

suppose that A is our number of two digits, this means that:

3*A - 5 < 2*A + 8

It makes sense to start with the smaller number of two digits, 10.

3*10 - 5 < 2*10 + 8

25 < 28

this is true.

Now let's check the next one, 11.

11*3 - 5 < 2*11 + 8

28 < 30

This is true again, now let's try with the next one, 12.

3*12 - 5 < 2*12 + 8

31 < 32

This is true again, now let's find the last one.

3*13 - 5 < 2*13 + 8

34 < 34

this is not true, so the numbers that fulfill the condition are 10, 11, and 12.

A faster way to prove it is, suppose that both sides of our inequality are equal, then find the value of A.

3*A - 5 = 2*A + 8

3*A - 2*A = 8 + 5 = 13

A = 13

This means that any number of two digits less than 13 fulfills the condition, those numbers are 10, 11, and 12.

A local hamburger shop sold a combined total of 389 hamburgers and cheeseburgers on Thursday. There were 61 fever cheeseburgers
allsm [11]

Answer:

  225

Step-by-step explanation:

Let h represent the number of hamburgers sold. Then h-61 is the number of cheeseburgers sold. The combined total is ...

  h +(h -61) = 389

  2h = 450 . . . . . . add 61

  h = 225 . . . . . . . divide by 2

There were 225 hamburgers sold on Thursday.

f a rectangle has a perimeter of 70, a length of x and a width of x - 9, find the value of the length of the rectangle.
trasher [3.6K]

( x + (x  -  9))  \times 2 = 70 \\( 2x - 9) \times2= 70 \\ 4x - 18 = 70 \\ 4x = 70 + 18 = 88
x =  \frac{88}{4}  = 22
the length is 22


and the width is
22-9=17





good luck

The manager at Gabriel's Furniture Store is trying to figure out how much to charge for a bookshelf that just arrived. The books
melomori [17]

First: markup rate × wholesale price = amount of markup

Second: Well the markup rate is a percentage, you have to convert it into a decimal. Percent means "out of one hundred," so <span>80%</span> is equivalent to <span>80/100 </span>which is also equal to <span>80÷100</span>.

<span>Third: 80÷100=0.80</span>

0.80 × $93.00 = $74.40

Fourth: The markup rate is a percentage of the wholesale price that is added to get the retail price, you can find the retail price with the following equation: amount of markup + wholesale price = retail price

<span>$74.40</span> + <span>$93.00</span> = <span>$167.40</span>

The retail price of the chair should be <span>$167.40</span>.
