Answer:
The relationship between two variables is decreasing and linear.
Step-by-step explanation:
From the given table it is notice that the function passing through the points (1,5), (2,-1), (3,-7) and (4,-13).
Slope of the function between first two points (1,5) and (2,-1) is
Slope of the function between last two points (3,-7) and (4,-13) is
The rate of change or slope of the function is constant.
From the given table it is noticed that the values of y decreased by 6 units as the values of x increased by 1 units.
Since the rate of change constant and negative, therefore the relationship between two variables is decreasing and linear.
Given that the<span> iq scores for large populations are centered at 100.
To get what percent of these 78 students have scores above 100 we conduct a normal distribution probability of the data.
P(x > 100) = P(z > (100 - 100)/sd) = P(z > 0) = 1 - P(z < 0) = 1 - 0.5 = 0.5 = 50%

Answer:
- a) 6.5 seconds
- b) 13 seconds
- c) 679 ft
Step-by-step explanation:
<u>Given function:</u>
a) <u>Maximum height is the vertex.</u> The ball reaches the maximum after:
- h = -208/2(-16) = 6.5 seconds
b) <u>Time the ball was in the air:</u>
Solving we get approximately t = 13 seconds
c) <u>Maximum height is at vertex, we found t above:</u>
- h(6.5) = -16(6.5)^2 + 208*6.5 + 3 = 679 ft
Answer:
The length of the trip is 1.5
Step-by-step explanation:
5÷100×30=1.5
A) reflect graph over x-axis (minus in front)
e) compress the graph to the x-axis (coefficient 1/2)
f) translate the graph to the right (x-9), minus between x and 9.
