Answer:
Step-by-step explanation:
This is an algebraic question type where we express the identity of each number using exactly four 4s method order of operation.
So, Expression using four 4s.
1 = (4 ÷ 4) ÷ (4 ÷ 4)
2 = ( 4 ÷ 4 ) + ( 4 ÷ 4)
3 = ( 4 + 4 + 4 ) ÷ 4
4 = 4 + 4 ( 4 - 4 )
5 = ((4 × 4) +4) ÷ 4
6 = 4 +( (4+4) ÷ 4)
7 = (4+4) - ( 4 ÷ 4 )
8 = (4 × 4) - 4 - 4
9 = 4 + 4 + ( 4 ÷ 4)
10 = ( 44 - 4 ) ÷ 4
The solution to the problem is as follows:
<span>Let be X: scores of SAT
P(X ≥ x) = 0.9
P((X - 500)/100 ≥ (x - 500)/100) = 0.9
P(Z ≥ z) = 0.9
z = 1.28
1.28 = (x - 500)/100
128 + 500 = x
x = 628

Answer:
The slope is 0.5 or (1/2)
Step-by-step explanation:
Find the rise over run.
from -3 to -1 and 2 to 3 rises 1 runs 2 so then you divide 1/2 and get 0.5.
