There are 31+42+50+61=184 total females, and 50+61=111 females in grades 11 and 12, so the percentage is 111/184*100=60.33 percent, which can be rounded to 60%.

Answer:

Option C- 60%

Step-by-step explanation:

Given :

Gender :  Grade 9       Grade 10        Grade 11       Grade 12

Male:            53                 19                   27                 37

Female:         31                 42                  50                 61

To find : Percentage of females are in grades 11 and 12

Solution: Total number of females= 31+42+50+61= 184

Number of females in grades 11 and 12 = 50+61 = 111

Percentage of females are in grade 11 and 12 = (No. of females in 11 and 12/total no. of females) × 100

\Rightarrow \frac{111}{184}\times100=\frac{11100}{184}=60.32

Percentage is approx. = 60%

Therefore, option C is correct

Answer:

y = (x-0)^2 + (-5)  ⇒ y = x^2 - 5

Step-by-step explanation:

The general vertex form of the parabola  y = a(x - h)² + k

Where (h,k) is the coordinates of the vertex.

As shown at the graph the vertex of the parabola is the point (0, -5)

So,

y = a(x-0) + (-5)

y = ax^2 - 5

To find substitute with another point from the graph like (1,-4)

So, at x = 1 ⇒ y = -4

-4 = a * 1^2 - 5

a = -4 + 5 = 1

<u>So, the equation of the given parabola is ⇒ y = x^2 - 5</u>
