Answer:
0.701
Step-by-step explanation:
0.299=299/1000
probability of not happening=1000-299/1000
=701/1000
=0.701
hope I helped

2.
(a) 200/4=x
(b) Yvonne is 50 because 50 times 4 is equal to 200
(c) Xavier is 43 because if you subtract 7 from 50 (which is Yvonne's age) you get 43
You form both equations into one equation and solve for x. Then you would add in the value and solve. The like PQS is equal to 180 degrees. You would first do (3x-5) + (x+1) = 180.
Solving the expression we get -2.
Comparing the solution with the one given, you can find the errors.
Step-by-step explanation:
We need to simplify and identify errors.
Since the steps are not shown, so we cannot identify errors but I can solve the expression and you can compare to find errors.
Simplifying:
Using algebraic rule: if one digit has positive (+) sign and other digit has negative (-) sign then we will perform subtraction. and after subtraction, the sign of bigger value will be the sign of result.
Using the rule and solving:
Solving the expression we get -2
Comparing the solution with the one given, you can find the errors.
