Answer:
y = 3/4x +2
Step-by-step explanation:
The slope intercept form of an equation is
y = mx+b
where m is the slope and b is the y intercept
Y-intercept=(0,2) slope=3/4
y = 3/4x +2
Use one of the equations of motion under constant acceleration:-
s = ut + 0.5at^2 where s = distance, u - initial velocity, a = acceleration ( in this case it is gravity = 9.81 m s^-2) and t = time.
here we have s = 25*2 + 0.5*9.81 * 2^2
= 69.62 meters answer
Answer: The height of the building is 69.6 m
Explanation:
To calculate the height of the building, we use second equation of motion:
where,
s = height of the building = ?
u = initial velocity of the ball = 25 m/s
a = acceleration due to gravity =
t = time taken = 2.0 sec
Putting values in above equation, we get:
Hence, the height of the building is 69.6 m
Answer:
Graph A
Step-by-step explanation:
We can plug the function into a graphing calculator and check to see which graph matches up.
Let x be the number of pounds of ice cream and y be the number of pounds of pickles that Dakota purchases. State the inequality that represents his budget, and graph the solution that represents the possible combinations of x and y. Express your answer with the standard form ax+by on the left side.
The budget inequality is _________________________
Answer: 5x + 4y ≤ 100
Step-by-step explanation:
5x + 4y ≤ 100
It has to be ≤ 100 because the dude only has $100 and can't exceed that.

b) Response bias
c) Non-response bias
d) Selection bias
Answer: Selection bias
Step-by-step explanation:
From the question, we are informed that a travel agency contacted a department store and obtained the list of all people who made purchases using their credit cards at the store in the last month. The agency then surveyed a random sample from the list, calling them to ask their preference for air travel or train travel for taking holidays.
The bus depicted above is referred to as the selection bias. The selection bias is simply a bias that is introduced when the sample obtained is not a representation of the population that the researcher wants to analyze. Here, the study population doesn't represent the target population.
The list gotten was for the people who made purchases using their credit cards but the agency used the list to determine the preference for air travel or train travel for taking holidays. This shows selection bias.
