A plane is on its approach to land on the runway. The jet's height above the ground is given in feet as a function of the time in seconds. The following table tracks the plane as it lands:

Calculate the slope. Use the formula -
What is the significance of the sign of the slope?
a. The plane is losing altitude.
b. The plane is gaining altitude.
C The plane is remaining at a constant height.
d. The plane is losing altitude at a rate of 500 feet/second.

H(x)=4x2-5x h(-3) what is the answer?

Angela is buying a dress that is on sale for 20% off. if the original price of the dress is $40.00, how much money is angela saving on the dress? a. $0.80 b. $3.20 c. $32.00 d. $8.00

The null and alternate hypotheses are: h0: μ1 ≤ μ2 h1: μ1 > μ2 a random sample of 22 items from the first population showed a mean of 113 and a standard deviation of 12. a sample of 16 items for the second population showed a mean of 99 and a standard deviation of 6. use the 0.01 significant level. find the degrees of freedom for unequal variance test. (round down your answer to the nearest whole number.) state the decision rule for 0.010 significance level. (round your answer to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? use the 0.01 significance level.
