Answer:
1.) 86=(1/3)B(6)
2.)43.00 square feet
Step-by-step explanation:
N/A
Given:
Mean, μ = 196
Std. dev., σ = 22
A sample size of 50 (> 30) is large enough to provide meaningful data.
The random variable is x = 200.
The z-score is
z = (x - μ)/σ = (200 - 196)/22 = 0.1818
From normal distribution tables, obtain
Prob(X < 200) = 0.572 = 57.2%
Answer: 57.2%
Answer:
85
Step-by-step explanation:
Order of operations rules (PEMDAS) govern here. Anything inside parentheses must be done first, followed by exponentiation, mult. and div., and add. and subtr. last.
Add 2+5 first: 5 + 2*{(7)*5 + 5}
Perform the work shown inside the brackets { and }: 5 + 2*{40}
Perform the indicated mult.: 5 + 80
Finally, add: 85
Answer:
1:3
Step-by-step explanation:
Both numbers are divisible by 25:
∴ The simplified ratio is 1:3
Hope this helps!
