Answer:
am not sure but I think the answer is79.02
Answer:
Median is the middle line of the box, Lower quartile is the number of the lower end of the box, Upper quartile is the line at the larger end of the box, Maximum is the largest number in the box plot (end of right whisker), Minimum is the lowest number (end of left whisker).
Step-by-step explanation:
32.
Median: 88
Maximum (largest number): 102
Minimum (lowest number): 38
Interquartile range:
96 - 72 = 24
b.
25 % higher
75 % lower?
c.
You can see the range is more towards the right of the box meaning they have higher scores, and that the median or middle is a higher number so it means that most of the students understood and did well on the test.
???.
First quartile: 16
Second: 19
Third: 20
Range: 4
34. Since they are already in least to greatest order, all we have to do is graph it!
85 - 99 is 2
100 - 114 is 1
115 - 129 is 5
130 - 144 is 6
Answer:
35cm²
Step-by-step explanation:
(7 x 10) ÷ 2 = 35
Area equation: (b x h) ÷ 2 = a
Let
b1-------------> base <span>△ABC
b2-------------> base </span><span>△DEF
A1-----------> area </span>△ABC
A2-----------> area △DEF
we know that
h1=20 in
h2=24 in
A1=b1*20/2-------------> A1=10b1
A2=b2*24/2 ------------> A2=12 b2
if <span>△ABC∼△DEF
</span>then
b1/20=b2/24------------> b1=b2*[20/24]-----> b1=b2*[5/6]
<span>What is the ratio of the area of △ABC to the area of △DEF?
</span>A1=10b1
A2=12b2
A1/A2=(10/12)*(b1/b2)-------> (10/12)*(b2*(5/6)/b2)-----> (10/12)*(5/6)=50/72
A1/A2=50/72--------> 25/36
the answer is (25/36)
