Answer:
There were 169 children at the pool.
Step-by-step explanation:
Given:
Total number of people = 550
Price per child = $1.75
Price per adult = $2.25
Total cost of the admission receipts = $1153.00
Let the number of children be 'x' and number of adults be 'y'.
As per question:
Total number of people is equal to total children and total adults. So,
Total cost of admission is equal to the sum of cost of total children and total adults. So,
Multiplying equation (1) by 1.75 and subtracting the result equation from equation (2). This gives,
So, there were 381 adults at the pool. Now, the number of children is equal to:
Therefore, there were 169 children at the pool.
Answer:
std deviation = 1.641
Step-by-step explanation:
Given that the TSH (Thyroid Stimulating Hormone) levels among healthy individuals are normally distributed with a mean of 3.1 units/mL.
If X represents the TSH then X is N(3.1, sigma)
We do not know sigma value, but we are given that exactly 95% of healthy individuals have TSH levels below 5.8 units/mL.
We know as per standard normal distribution score that 95th percentile referes to Z score of 1.645
Using this we can find standard dev
Answer:
x = 6
Step-by-step explanation:
→ Rewrite equation
x + 3 = 9
→ Minus 3 from both sides
x = 6
