(x-6)/2 = 8
x-6 = 16
x = 22
150 + 55 = 205
11.50 x 4 = 46
205 + 46 =$251

Answer:
4/663
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Since we are to draw from a pack of card, the total outcome will be 52
Since there are 4 hearts;
Pr(selecting heart) = 4/52 = 1/13
If a club is then selected without replacement, the total number of card remaining will be 51;
Pr(selecting a heart) = 4/51
probability of drawing a heart and a club in that order = 4/52 * 4/51
probability of drawing a heart and a club in that order = 16/2652
probability of drawing a heart and a club in that order = 4/663
Answer:
20
Step-by-step explanation:
The interquartile range is found by subtracting Q1 and Q2. We first need to identify the median to do this we cross out from each side until one or two are left in the middle.
<span>437, 456, 513, 650, 893 , 954, 1018, 1038, 1117, 1465
</span>
The median is <span>923.5 found by 893 + 954 / 2 = 923.5
</span>Now we identify the lower median and upper median.
<span>
</span>Lower set: 437, 456, 513, 650, 893
Upper set: 954, 1018, 1038, 1117, 1465
Lower set median or Q1: 513
Upper set median or Q3: 1038
We now would find the difference of the two to get the interquartile range.
Interquartile Range: 1038 - 513 = 525
