Answer:
mean: 13
range: 15
there is no mode
median: 13.5
Step-by-step explanation:
mean= 14+9+20+5+17+13 = 78
78÷6= 13
range = highest number minus the smallest number
20-5 = 15
the mode is the number that occurs the most
median= 13+14= 27
27÷2 = 13.5
Answer:
width = 15
Step-by-step explanation:
a² + b² = c² This the the formula
(PLUG IN)
8² + b² = 17²
64 + b² = 289 (subtract 64 on both sides)
b² = 225 (square root)
b = 15
Hope this helps ya!!
Answer:
c = 9
Step-by-step explanation:
-2c = -18
/-2 /-2 (Divide both sides by -2)
_______
c = 9
Answer:
12 is the denominator.
Step-by-step explanation:
<u>Here's a trick:</u>
If your ever making a proportion or equivalent fractions, always see what number the numerator/denominator is multiplied by to make the equivalent fraction.
In our case we have 3 being multiplied by x to get 18.
Since this is just 18 divided by 3, we ge that x = 6.
Now we can figure out our denominator's value.
We will multiply 2 times x to get our answer.
Since x = 6, we have 2 * 6 = 12 is our answer.
<u>Check:</u>
When we simplify, our answer should be equivalent to 3/2. If it isn't we've made a mistake. 18/12 = 6/4 = 3/2 so we are correct.
