A correctly displays the number.

Step-by-step explanation:

Mrs. Rodriquez has 24 students in her class. Ten of the students are boys. Jeff claims that the ratio of boys to girls in this class must be 5:12. What is Jeff’s error and how can he correct it?Jeff found the ratio of the number of boys to the total number of students. He needed to first find that there are 14 girls to get a ratio of 10:14 or 5:7.Jeff found the ratio of the number of boys to the total number of students. He needed to first find that there are 14 girls. The ratio would be 14:10 or 7:5.Jeff did not write the ratio in the correct order. He should have written it as 24:10.Jeff did not write the ratio in the correct order. He should have written it as 12:5.

Answers

Answer:

The correct option A.

Step-by-step explanation:

Total numbers of students = 24.

Number of boys = 10

Number of girls = 24 - 10 = 14

Jeff claims that the ratio of boys to girls in this class must be 5:12.

The ratio of the number of boys to the total number of students is

(boys)/(students)=(10)/(24)=(5)/(12)=5:12

Therefore Jeff found the ratio of the number of boys to the total number of students.

The ratio of boys to girls in this class is

(boys)/(girls)=(10)/(14)=(5)/(7)=5:7

Therefore the ratio of boys to girls in this class is 5:7.

Option A is correct.
The ratio is 10:14 or 5:7 which is the ratio of boys to girls!

Can someone solve this differentiation question.

Answers

We clearly see on the graph that :
A. f is increasing on (2,6) and (8,10) (the derivative is >=0)
B. f is decreasing on (0,2) and (6,8) (the derivative is <=0)
C. f has two relative minima : one at x=2 and one at x=8 (the derivative changes signs there from negative to positive)
D. f has two relative maxima : one at x=6 and one at x=10(the derivative changes signs there from positive to negative)
E. f is concave up when f' is increasing i.e. on (0,4) and (7,9)
F. f is concave down when f' is decreasing i.e. on (4,7) and (9,10)
G. the points of inflexion of f are the points at which f' has an horizontal tangent, thus they are at x=4, x=7 and x=9
H. see the picture attached

A).  The function is increasing where its derivative is positive.
Its derivative is positive from 2 to 6, and from 8 to 10.

B).  The function is decreasing where its derivative is negative.
Its derivative is negative from 0 to 2, and from 6 to 8.

C).  The function has a relative minimum where its derivative is zero
and changing from negative to positive.
Its derivative is zero and changing from negative to positive at 2 and 8.

D).  The function has a relative maximum where its derivative is zero
and changing from positive to negative.
Its derivative is zero and changing from positive to negative at 6 and 10.

E).  The function is concave up between consecutive relative maxima.
The interval between consecutive relative maxima is  6 < x < 10 .

F).  The function is concave down between consecutive relative minima.
The interval between consecutive relative minima is  2< x < 8 .

G).  The function has points of inflection where its second derivative is
zero, that is, where its first derivative is a relative minimum or a relative
maximum.
Its first derivative is a relative minimum or maximum at x =  0,  4,  7, and  9 .

H).  Good luck on the sketch !

Which word phrase can you use to represent the algebraic expression 6y

Answers

C. The product of 6 and a number y.
6 times y.  one way to do these is read it out loud, and if that doesn't help than try explaining what the expression says, out loud. so you would read this as "six y", or you could explain it as 6y is saying you have y six times
