Answer:

33.8

Step-by-step explanation:

1) Use Phythagoras theorem to get RS ↓

9.1 ^{2}  + 6 ^{2}  = 118.81 \\  \sqrt{118.81 }  = 10.9

2) RS = RQ

therefore, to get the perimeter, you'll have to total up the sides of the triangle ↓

rs + rq +qt +  ts   \\ = 10.9 + 10.9 + 6 + 6  \\ = 33.8

Hope this helps =)

factorise the following 1. x²-2x+15.... 2. y²-19y+90​
Marta_Voda [28]

Answer:

1. x²-2x+15

This can't be factored, I've tried multiple ways now, but it just can't be factored.

2. y²-19y+90​

Let's factor y^2−19y+90

y^2−19y+90

The middle number is -19 and the last number is 90.

Factoring means we want something like

(y+_)(y+_)

Which numbers go in the blanks?

We need two numbers that...

   Add together to get -19

   Multiply together to get 90

Can you think of the two numbers?

Try -9 and -10:

   -9+-10 = -19

   -9*-10 = 90

Fill in the blanks in

(y+_)(y+_)

with -9 and -10 to get...

(y-9)(y-10)

Answer:

(y−9) (y−10)

consider the gre scores for a random sample of 6 students out of a class of 25: name julia andrew jason cathy jessica robert sco
Thepotemich [5.8K]
Name  Score
Julia      650
Andrew 550
Jason    380
Cathy    720
Jessica 710
Robert   550

Point estimate for the mean score:
Sample mean = sum of all observations / number of observations

sample mean = (650+550+380+720+710+550) / 6
sample mean = 3560 / 6 
sample mean = 593.33

The point estimate for the mean score is 593.33
