Answer:
0.61 ( A )
Step-by-step explanation:
The standard proportion of Sugar, lemon juice and water needed to make a Lemonade is Usually 1 cup each
But If you Intend to make Your lemonade less sweet you can increase the water or reduce the amount of sugar to ≈ 1 ( i.e. less than 1 but approximately = 1 )
Hence The appropriate amount of sugar needed will be = 0.61
Answer:
1
Step-by-step explanation:
If P(E) = p
Then P(not E) = 1-p
Say that xyz is your number, then y=4z and x+3=y
Since it is a multiple of 4, y has to be 4 or 8, which means z has to be 1 or 2, since it is 1/4 of y and then since x is 3 less than y, x would have to be 1 or 5...so the numbers are....141 or 582
B. a rigid transformation was performed. Am I right or wrong?
Answer:
0.26599
Step-by-step explanation:
When given a random number of samples, we solve using this z score formula
z = (x-μ)/σ/√n
where x is the raw score = 268
μ is the population mean = 266
σ is the population standard deviation = 16
n = 25
For x > 268
z = 268 - 266/16/√25
z= 2/16/5
z = 0.625
Probability value from Z-Table:
P(x<268) = 0.73401
P(x>268) = 1 - P(x<268)
P(x>268) = 1 - 0.73401
P(x>268) = 0.26599
The probability that the average pregnancy length of the women in the study is more than 268 days is 0.26599
