Answer:
32 + 4x ≤ 50
Step-by-step explanation:
Cost of tickets = $32
Cost of soda = $4
Total spent = $50
When we say "no more than", we mean less than or equal to (≤)
He buys 1 tickets and x sodas
32 + 4x ≤ 50
4x ≤ 50 - 32
4x ≤ 18
Divide both sides by 4
x ≤ 18 / 4
x ≤ 4.5
Shawn can buy more than 4 sodas
Sorry But I can't understand what − means so i will solve this for x+3 and x-3
first for x+3
equation e= x(x+3)(x+4)>0
so points are x= 0,-3,-4
for range x<-4
e<0
for -4<x<-3
e>0
for -3<x<0
e<0
and for x>0
e>0
so the interval when e>0
x â (-4<x<-3 and x>0)
now for x-3
equation e=x(x-3)(x+4)>0
so points are x= 0,3,-4
for range x<-4
e<0
for -4<x<0
e>0
for 0<x<3
e<0
and for x>3
e>0
so the interval when e>0
x â (-4<x<0 and x>3)
Answer:
A. The distribution should be skewed to the left because the mean is less than the median.
B. Most students scored a C or higher.
Step-by-step explanation:
A. Since mean<median<mode, we have a negative skewness and hence the distribution is skewed to the left.
B. Since the mean score is 71 and the modal score is 81, it is expected that a 'C' should be the lowest grade most students will have.
