Answer: See explanation
Step-by-step explanation:
Your question isn't really clear but let me help.
For Maths test,
Point earned = 30
Total point = 43
Percentage = 30/43 × 100 = 69.77%
Social studies test
Point earned = 85.
Total point = 124
Percentage = 85/124 × 100 = 68.55%
From the above, we can see that Jake scored a higher percentage in the Maths test.
Answer:
yes
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
a)
minimum = 45
first quartile = 55
median = 75
third quartile = 85
maximum = 95
lower fence = Q1 - 1.5 x IQR = 10
upper fence = Q3 + 1.5 x IQR = 130
Therefore, one outlier = 140
b) mean = sum of all numbers ÷ n = 760 ÷ 10 = 76 ($76,000)
There is an outlier (140). Outliers don't affect the median as much as they affect the mean.
c) see attached
d) negative skew
Answer:
any number greater than -2
Step-by-step explanation:
4 - 5y < 14
step 1: subtract 4 from each side "
4 - 4 cancels out
14 - 4 = 10
now we have -5y < 10
step 2: divide each side by -5
-5y/-5=y
10/-5=-2
( IMPORTANT NOTE: WE MUST FLIP THE INEQUALITY SIGN IF WE DIVIDE BY A NEGATIVE NUMBER)
We would be left with y > -2
3400. Should be the answer. I’m sorry if it is incorrect
