Answer:
About 91%
Step-by-step explanation:
According to the box plot provided :
Total number of students = 40
Minimum weight = 152 pounds
Third quartile (Q3) = 245
The approximate percentage of students that weigh 245 kg or less
About 10 of the intervals out of the 11 coverage interval of the box plot fall between 152 and 254 ; Hence,
(10 / 11) * 100
90.90
= about 91 % of the total students weigh 245 kg or less
Answer:
The price of the jacket was $31.43
Step-by-step explanation:
Let the cost of a jacket = x
Let the cost of a pair of pants = y
Such that,
x + y = $66.12.........Equation 1.
From the conditional statement,
x = y - $3.26..........Equation 2.
Solve both equations simultaneously, using the substitution method
From Equation 2;
x = y - 3.26
Substitute y - 3.26 for x in Equation 1.
x + y = 66.12, now becomes,
y - 3.26 + y = 66.12
collect like terms
y + y = 66.12 + 3.26
2y = 69.36
y= 69.36/2 = $34.69.
Put y = $34.69 in Equation 2. to obtain x
x = 34.69 - 3.26
x = $31.43
