Answer:
7.549, , 8.59, 8
Step-by-step explanation:
You notice the last 2 in the sequence are decimals. So you convert everything else to decimals too.
So begin with dividing 171/20 which gets you 8.55
Then convert the second fraction to a regular fraction, by multiplying the denominator by the bigger number beside it, 8.
So 8 * 11 = 88
Then add the numerator to the new product.
88 + 7 = 95
Then you have your new numerator.
Take that and divide by 11
95/11 = 8.63
So from least to greatest is
7.549, , 8.59, 8
Answer: -9 degrees Fahrenheit
Step-by-step explanation:
Given: Temperature at 6:00 AM = -12 degrees Fahrenheit
Temperature increased each hour = degrees Fahrenheit
Temperature increase in 6 hours =
Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours
= -12+3 degrees Fahrenheit
= -9 degrees Fahrenheit
Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit
function g has to be the transformation of function f. Therefore,
is the answer.
Answer:
The margin of error for the true mean number of hours a teenager spends on their phone is of 0.4 hours a day.
Step-by-step explanation:
We have the standard deviation of the saple, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 50 - 1 = 49
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 49 degrees of freedom(y-axis) and a confidence level of . So we have T = 2
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
The margin of error for the true mean number of hours a teenager spends on their phone is of 0.4 hours a day.
