Z-scores (left tail) of a given variable X are calculated by
Z(x)=(x-mean)/standard deviation.
For Mary:
Zm(124)=(124-110)/8=14/8=1.75
For Carrie:
Zc(289)=(289-250)/20=39/20=1.95
therefore
Zc>Zm
Answer:
- 11/20
Step-by-step explanation:
1/5 - 3/4
Make denominators equal.
4/20 - 15/20
Subtract the fractions.
- 11/20
<em>The answer is Ms Hernandez can bring up to 6 people to the zoo.</em>
<em />
<em>x - the number of people that she can bring to the zoo</em>
<em>The parking will cost $7: a = 7</em>
<em>Admission tickets will cost $15.50 per person: b = 15.50x</em>
<em>She can spend on parking and admission tickets $100:</em>
a + b ≤ 100
a = 7
b = 15.50x
7 + 15.50x ≤ 100
15.50x ≤ 100 - 7
15.50x ≤ 93
x ≤ 93 / 15.50
x ≤ 6
Answer:
NO
Step-by-step explanation:
You should not agree.
Graphically the graph shows a wide difference, with roberts getting aboyt twice votes as the 2nd candidate. However, the ordinates axis is nos set beginning in 0, is starts in 900. This is a usual trick to make differences look grater than they are.
The three candidates together sum 2840 votes (980+920+940), and the difference between the first 2 is 40 votes, which represents only 1.4% of votes (40/2840).
So, the margin is not wide.
I believe it would be C) 7 1/q
