Some iq tests are standardized to a normal model n(100,10).
a) what cutoff value bounds the highest 10% of all iqs?
b) what cutoff value bounds the lowest 20% of the iqs?
c) what cutoff values bound the middle 90% of the iqs?
a) the cutoff value is
(round to one decimal place as needed.)

step-by-step explanation:

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
