Answer:
Step-by-step explanation:
Assuming the number of tickets sales from Mondays is normally distributed. the formula for normal distribution would be applied. It is expressed as
z = (x - u)/s
Where
x = ticket sales from monday
u = mean amount of ticket
s = standard deviation
From the information given,
u = 500 tickets
s = 50 tickets
We want to find the probability that the mean will be greater than 510. It is expressed as
P(x greater than 510) = 1 - P(x lesser than or equal to 510)
For x = 510
z = (510 - 500)/50 = 0.2
Looking at the normal distribution table, the probability corresponding to the z score is 0.9773
P(x greater than 510) = 1 - 0.9773 = 0.0227
Answer:
The number of people who visited museum on Saturday is 558.
Step-by-step explanation:
Number of people went to museum on Monday = 186
Also, the number of people triples on Saturday.
So, Number of people visited on Saturday
= 3 x Number of people who visited museum on Monday
= 3 x 186 = 558
Hence, the number of people who visited on Saturday is 558.

Step-by-step explanation:
180-110.. parallel angels
Answer:
x=19
Step-by-step explanation:
These two angles are alternate interior angles and alternate interior angles are equal when the lines are parallel
148 = 7x+15
Subtract 15 from each side
148-15 =7x+15-15
133 = 7x
Divide by 7
133/7 = 7x/7
19 =x
34
16^2 = 256
30^2 = 900
900+256 = 1156
square root of 1156 = 34
