Lily has saved $ 7
<em><u>Solution:</u></em>
Given that bracelet costs $30
The bracelet Lily would like to buy costs $5 less than 5 times the amount she has saved
Cost of bracelet = $ 30
From given statement,
Cost of bracelet = 5 times the amount she has saved - 5
Let "x" be the amount saved by lily
Cost of bracelet = 5 times x - 5
Here "times" represents multiplication
30 = 5(x) - 5
30 = 5x - 5
30 + 5 = 5x
5x = 35
On dividing 35 by 5 we get 7
x = 7
Thus Lily saved $ 7
Find the probability of Red/small.
Red = large + small
large = 8
Small = 12
Plug in 8 for large, and 12 for small
Red = 8 + 12
Red = 20
Now we know that the total red = 20
Do the same with small
3 small blue
12 small red
Small = blue + red
Small = 3 + 12
Small = 15
Note that red is first then small. Put red over small
Remember that red = 20, small = 15
20/15 is the fraction you need.
However, note that it says "reduce your answer" at the bottom
Divide 5 from numerator and denominator
(20/15)/(5/5) = 4/3
4/3 is your answer
hope this helps

Answer: x = 34º, y = 146º, z = 146º
Step-by-step explanation:
Adding the angles inside a triangle gives you 180º. So
85 + 61 + x = 180
146 + x = 180
x = 34º
x and y are supplementary, so y = 180 - x = 180 - 34 = 146º.
y and z are equal (vertical angles), so z = 146º.
Part A: The school with the lowest value of σ is High School B. This also is the school with the lowest IQR.
Part B: The highest mean is that of High School C, which has average attendance 11 more than the next lower school (A).
