Answer:
Hello! answer: y = 40 x = 67
Step-by-step explanation:
63 - 23 = 40 therefore y = 40
63 + 63 = 126 360 - 126 = 234 234 ÷ 2 = 117
67 × 2 = 134 134 - 17 = 117 therefore x = 67 hope that helps!
Answer:

Step-by-step explanation:
If we are scaling up the surface area by a factor of 10 means that the two dimensions of area are each being increased by 10 times the original size. Therefore, the surface area is increased by a factor of 10 x 10, or by a factor of 100.
U^16 is the answer to this problem
Answer:the z score is - 1
Step-by-step explanation:
Assuming a normal distribution for the delivery time of sandwiches by Sammy's Sandwich Shop. We would apply the formula for normal distribution which is expressed as
z = (x - u)/s
Where
x = delivery times
u = mean delivery time
s = standard deviation
From the information given,
u = 25 minutes
s = 2 minutes
We want to determine the z-score for the number of sandwiches delivered in less than 23 minutes. It becomes
z = (23 - 25)/2 = - 1
