Answer:
Josephine
Step-by-step explanation:
2 criteria was given to pass an exam:
1. At least, a mean mark of 40% must be achieved in the exam consisting of 4 papers
2. Score at least, 33% in each paper.
From the table given, and considering these two criteria, James definitely didn't pass the examination. He scored below 33% in one of the 4 papers. James scored 30% in Maths
Calculated the mean score for John and Josephine to determine if they meet the first criteria of having at least a mean score of 40%.
Mean score of John = (35 + 36 + 42 + 44) ÷ 4 = 39.25%
Mean score for Josephine = (60 + 55 + 38 + 75) ÷ 4 = 57%
Josephine passed the examination because she had a mean score of 57%, and also scored 33% and above in each test.

Answer:
2 and 2/3 inches
Step-by-step explanation:
v = l x w x h
= 
· 
· h
= 
h
cross-multiply to get 45 x 4 x h = 32 x 15
180h = 480
Answer:
x=-33/5 y=29/5
Step-by-step explanation:
Let's solve your system by substitution.
3x+y=−14;2x−y=−19
Solve
3x+y=−14 for y:
3x+y=−14
3x+y+−3x=−14+−3x(Add-3x to both sides)
y=−3x−14
Next is to substitute −3x−14 in for y 2x−y=−19:
2x−y=−19
2x−(−3x−14)=−19
5x+14=−19(Simplify both sides of the equation)
5x+14+−14=−19+−14(Add -14 to both sides)
5x=−33 Dived both sides by 5
5x/5=-33/3
x=−33/5 since you can't dived and a fraction is another form of division you keep it this way.
Step: Substitute -33/5 for x in y=−3x−14:
y=−3x−14
y=−3(-33/5)-14
y=29/5
(Simplify both sides of the equation)(since you can't dived and a fraction is another form of division you keep it this way.)
So
x=-33/5 and y=29/5
Pls mark brailest this took me a long time to write out lol. Hope this truly helps! Send a heart if so, so I can keep spreading the help!
Answer:
174cm^2
Step-by-step explanation:
Given data
L=9m
W=5m
H=3m
The formula for the total surface area of a cuboid is
SA=2lw+2lh+2hw
substitute
SA=2*9*5+2*9*3+2*3*5
SA= 90+54+30
SA= 174cm^2
Hence the surface area is 174cm^2
