The table shows the heights of students in a group. student height (in inches) a 49 b 48 c 41 d 45 e 47 what is the mean height of the students in the group? 41 inches 43 inches 46 inches 49 inches

Answer with Step-by-step explanation:

We are given height of students in inches as:

49,48,41,45 and 47

We have to calculate the mean height.

Mean is calculated by sum of all observations over number of observations.

i.e. Mean=sum of all observations/number of observations

Mean height=(49+48+41+45+47)/5

Mean height=230/5

Mean height=46

Hence, mean height of students is:

46 inches

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
