Answer:
3.C
Step-by-step explanation:
the line is going down so the slope is negative and the y intercept is 4. also to find the slope fine a point for example 1,1 so either go up or down the the next point like 0,4 so it up 3 and over one which is 3/1 which is just 3.
4.c
for the slope you go up 5 over 1 for and for the y intercept will always gave 0 and something beside it but sense it us 0 then you just done have one also you can just plot the points and make a line as well.
Answer:
7a^6b
Step-by-step explanation:
Using the pascal triangle to do this binomial expansion, we find out that the coefficient is 7. The a variables start at the power to which you are expanding and reduce by 1 for every consecutive term. The b variables start at the power of 0 and increase by 1 for every consecutive term. Using this information, we find out that the second term in the binomial expansion (a+b)^7 is 7a^6b
Note that the power of b in the second term is b^1 which is the same as b
Answer:
The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.
Step-by-step explanation:
In this problem we have a normal ditribution with mean of 4.0 in and standard deviation of 1.5 in.
The proportion of the trees that are expected to have diameters greater than 5 inches is equal to the probability of having a tree greater than 5 inches.
We can calculate the z value for x=5 in and then look up in a standard normal distribution table the probability of z.
The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.
Answer:
The error in his prediction is that he had too small of a sample size for the data to be reliable in how the trend would continue.
