Multiply 14 (the price of gas in 2000) by 19.9% (the price as a percentage of the 2000 price). 14 times 0.199 is 2.786. Therefore, it would cost $2.79 to fill the same gas tank in 1960.
Not 100% sure if this answer is correct, but this is what I got.
Answer:
Attached linear graph
Step-by-step explanation:
The value of e is a mathematical constant of 2.72 approximately. We can consider this a constant as 1. Therefore this is a straight line with a gradient/slope of -2 and a y-intercept of:
and x intercept of:
If V 90 mean √90 or square root of 90 than irrational number is C.
Good luck!!!
Answer:
a: 0.9544 9 within 8 units)
b: 0.9940
Step-by-step explanation:
We have µ = 300 and σ = 40. The sample size, n = 100.
For the sample to be within 8 units of the population mean, we would have sample values of 292 and 308, so we want to find:
P(292 < x < 308).
We need to find the z-scores that correspond to these values using the given data. See attached photo 1 for the calculation of these scores.
We have P(292 < x < 308) = 0.9544
Next we want the probability of the sample mean to be within 11 units of the population mean, so we want the values from 289 to 311. We want to find
P(289 < x < 311)
We need to find the z-scores that correspond to these values. See photo 2 for the calculation of these scores.
We have P(289 < x < 311) = 0.9940
(17x+19)+(19x-15)=180
36x+4=180
36x=176
x=44/9 which is approximately 4.8
