The science club is going to the space museum. The club consists of 27 students. If admission costs $6.50 for children ages 4-11 and $8.50 for children ages 12-17, how much will it cost for the entire science club's admission to the museum? Science Club Student's Ages
Age/Number of Students
10 4
11 11
12 7
13 3
14 2

A- 175.50
B-185.50
C-199.50
D-229.50

Answer

C

Step-by-step explanation:

There are 15 students ages 4 - 11, 15 x 6.50 = 97.50

There are 12 students aged 12 - 17, 12 x 8.50 = 102

102 + 97.50 = 199.50

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
