Answer:
a
b
Yes
Step-by-step explanation:
From the question we are told that
The probability that a random selected person of age 40 years or older is a jogger is
The probability that a random selected person of age 40 years or older is a male given that he/she jogs is
Generally the probability that a randomly selected person age 40 years or older is male and jogs
Generally it would be unusual because the probability that a randomly selected person age 40 years or older is male and jogs is greater than 0.05[border line for statistical significance]
2 x 6x - 2 x 5y - 7
12x - 10y - 7
They won 54 games and lost 108 games. I got 54 because 162 divided by 3 is 54. 54 times 2 equals 108. Add them together and it equals 162.
Buckets of Soil : Buckets of Peat Moss = 5 : 4
Since Mr Carver needs to use 324 buckets in all,
He needs to use 324 * 5/9 = 180 buckets of Soil and 324 * 4/9 = 144 buckets of Peat Moss.
Answer:
The equation is
Step-by-step explanation:
The exponential growth equation is , where
- a is the initial value (value y at x = 0)
- r is the rate of increasing in decimal
∵ The value of gold is appreciating 18% every hour
∴ r = 18%
∵ 18% = = 0.18
∴ r = 0.18
∵ The gold coin was worth $40 at the beginning of the crisis
∴ The initial amount is $40
∴ a = 40
∵ y represents the value of the gold after x hours
∴
- Substitute the values of a and r in the form above
∴
∴
The equation is
