The basic form of linear function is
y=ax+b
For finding the slope, use the slope formula.
(4-2)/(-2+1)= 2/-1=-2
We first found a which is -2.
Then insert any point to find the value of b. In this case, I will insert (1,-2).
-2=-2+b
b=-2+2=0
The linear graph is y=-2x
Mean is that. median is only at the middle. Not describe the set of numbers. Answer = Mean
The pictures too blurred, can you write it out?
Answer:
There is not enough statistical evidence in the sample taken by the veterinarian to support his skepticism
Step-by-step explanation:
To solve this problem, we run a hypothesis test about the population proportion.
Proportion in the null hypothesis
Sample size
Sample proportion
Significance level
Test statistic
Left critical Z value (for 0.01)
Calculated statistic =
Since, test statistic is greater than critical Z, the null hypothesis cannot be rejected. There is not enough statistical evidence to state that the true proportion of pet owners who talk on the phone with their pets is less than 37%. The p - value is 0.79860.
16% of 24 is 3.87
Rounding up you have 4 dimes.
A dime is worth 10c, so you have $.40 in dimes.
