1225*(1.578*10^-5)=1.933*10^-2
1.578*10^-5= 0.00001578
1225*0.00001578=0.0193305
0.0193305=1.933*10^-2
Answer:
1450
Step-by-step explanation:
this is actually mental math
Complete Question
Statistics professors believe the average number of headaches per semester for all students is more than 18. From a random sample of 15 students, the professors find the mean number of headaches is 19 and the standard deviation is 1.7. Assume the population distribution of number of headaches is normal.the correct conclusion at is?
Answer:
There is no sufficient evidence to support the professor believe
Step-by-step explanation:
From the question we are told that
The population mean is
The sample size is
The sample mean is
The standard deviation is
The level of significance is
The null hypothesis is
The alternative hypothesis is
The critical value of the level of significance from the normal distribution table is
The test hypothesis is mathematically represented as
substituting values
Looking at the value of t and we can see that so we fail to reject the null hypothesis.
This mean that there is no sufficient evidence to support the professor believe
We are given with two functions f(x) = log10 x and g(x) = 3x − 1 and is asked for the product of the two functions expressed as f(x) • g(x). The answer then is simply the product of the two functions, that is log x * (3x - 1). log 10 x is equal to log x.
Answer:
(5, 5), (7, 2), (3, 2)
Step-by-step explanation:
When reflecting a figure across the y-axis, the x value will be the opposite and the y value will remain the same
reflection across y-axis:
(x, y) ---> (-x, y)
