Answer:
Nico
Step-by-step explanation:
In order to compare who had the best performance on the aptitude test, we can use Z score. Z score indicates how many standard deviation a result is over the mean. For this case the higher the result is, the best is the performance on the aptitude test.
Z score is expressed with the following formula:
Z=(X-μ)/σ
Where:
X is the test score
µ is the mean
σ is the standard deviation
Replacing in the formula we obtained
For Nico:
X = 88.3
µ = 66.2
σ = 13
Z=(88.3-66.2)/13=1.7
For Justin:
X = 226.2
µ = 216
σ = 17
Z=(226.2-216)/17=0.6
For Tera:
X = 7.97
µ = 7.2
σ = 0.7
Z=(7.97-7.2)/0.7=1.1
Nico had the higher Z score which means he had the better performance on the test and he should be offered the job.
Answer:
Yes, they are
Step-by-step explanation:
Because they both end with cd, they are like terms. Anything with the same ending letters are like terms.
Answer: B
Perimeter= 92.52
x=28.09
y=39.43
Step-by-step explanation:
sin39/25=sin44/x
x=28.09
sin97/y=sin39/25
y=39.43
39.43+28.09+25= 92.52
Answer:
7.5 feet long
Step-by-step explanation:
if I had one, 5 foot sandwich, I would have 8 pounds. if I had 2.5 more foot of sandwich I would have 4 more pounds ( because 2.5 feet is half of 5 feet which means we would have to divide 8 pounds by 2). which means I have 8 pounds and 4 pounds, which equals 12 pounds. I also have 5 feet and 2.5 feet of sandwich which is equal to 7.5 feet. since it's asking the length of a 12 pound sandwich, your answer is 7.5 feet long.
first you start with 0 then you know that is yours nothing so you can cancel zero and then you can take the eight can round up so you take the 8 and put it one more to do so it's $4 so in total will be $4 that's the answer
