Hii i’ll give brainliest please help thanks :)

the second one

Step-by-step explanation:

The median score will stay at 91.

Step-by-step explanation:

First put the numbers in order from greatest to least:

87, 88, 91, 91, 95, 100

Then find the median (middle) because there are two in the middle that are the same, it's just that number.

Next, add the other numbers.

86, 87, 88, 88, 91, 91, 95, 98, 100, 100

Find the median again, which is still 91.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
