Answer:
23 units
Step-by-step explanation:
Use the distance formula: d = 
Plug in the 2 points:
d = 
d = 
d = 23
So, the distance is 23 units

Step-by-step explanation:
Answer:
We cannot determine the appropriate hypotheses to test this study because we are only given the data for the sample size and the population mean. Meanwhile, we need to know the data of the sample mean, the standard deviation and the level of significance before we can state the appropriate hypotheses for this test.
Step-by-step explanation:
Given that:
sample size n = 300
population mean μ = 35
The null hypothesis and the alternative hypothesis can be computed as follows:
Null hypothesis

Alternative hypothesis

The degree of freedom df = n -1
df = 300 - 1
df = 299
Answer: The concentration will be 8 milligrams per liter at 2 hours and 4 hours.
Step-by-step explanation:
GIven: The concentration of a certain painkiller supplied by serum varies in its effectiveness over time according to the following function,
where C is the concentration of the painkiller in the serum measured in milligrams per liter so that it takes effect during t hours.
Put C(t)=8, then we get

At t=2, 
At t=4, 
Hence, the concentration will be 8 milligrams per liter at 2 hours and 4 hours.
The probability that Olive flips heads and rolls an even number is 3/12 or 1/4.
These events are known as independent events which means the result of one event will not affect the other. The find the probability of the two events, you must multiply the probability of flipping heads and rolling an even number on a number cube.
1/2 x 3/6 = 3/12 OR 1/4 :)
