Answer:
57.3
Step-by-step explanation:
just rounded up one
We have the sample size, sample mean and the sample standard deviation. Since the population standard deviation is not know, we will use t-distribution to find the confidence interval.
The critical t value for 95% confidence interval and 63 degrees of freedom is 1.998.
The 95% confidence for the population mean will be:
![(119-1.998 *\frac{16}{ \sqrt{64} } ,119+1.998 *\frac{16}{ \sqrt{64} }) \\ \\ =(115.004, 122.996) \\ \\=(115,123)](https://tex.z-dn.net/?f=%28119-1.998%20%2A%5Cfrac%7B16%7D%7B%20%5Csqrt%7B64%7D%20%7D%20%2C119%2B1.998%20%2A%5Cfrac%7B16%7D%7B%20%5Csqrt%7B64%7D%20%7D%29%20%5C%5C%20%20%5C%5C%20%0A%3D%28115.004%2C%20122.996%29%20%5C%5C%20%5C%5C%3D%28115%2C123%29)
Thus, the 95% confidence interval for the population mean will be (115,123)
So, option A is the correct answer
a. 4/5 because
the equation to find slope is
y2-y1 divided by x2-x1
which is -5-(-1) divided by -2-3 which is -4/-5 which is 4/5.
Answer:
As x approaches negative infinity, p(x) approaches positive infinity and q(x) approaches negative infinity.
Step-by-step explanation:
The order of the polynomial and the sign of the leading coefficient will let us find the correct answer easily,
If you get a negative number (such as negative infinity) and you take it to an odd power, (for example 3), you will still get a negative number.
As q(x) has a positive leading coefficient, this means that as x approaches negative infinity, q(x) will approach too negative infinity.
Since p(x) has an odd degree, but negative leading coefficient,
(-)*(-) = +
And this means that p(x) approaches positive infinity
Answer: x=2.375937.... sorry I give you the wrong one but here the steps O here x=2.96423 will it can be any one of the two answer I give you now.
Step-by-step explanation: Hope this help :D
