If you are describing transformations with respect to the graph of f(x) = x:
f(x) = x has no transformation
g(x) = (x+2) - 3 is the graph of f(x) translated 2 units left and 3 units down
2(h(x) = x-1) is the graph of f(x) vertically expanded by a factor of 2 and then translated 1 unit right
d(x) = 1/2x + 2 is the graph of f(x) vertically compressed by a factor of 1/2 and then translated 2 units up
Answer:
Step-by-step explanation:
Given that a study was conducted to find out if a new exercise program was more effective than an old one at improving cardiovascular fitness.
Subjects were randomly selected to participate and then randomly assigned to one of the two programs. After six months of exercising, they were given a score based on their fitness performance. Scores ranged from 19 to 73, with higher scores indicating higher performance.
Here there are two groups one for each program. After recording the scores groupwise, mean, std deviation of each group to be calculated.
Then independent sample test (option B) to be done.
Paired data set is not right because same person cannot be in two programs.
Here proportion is not recorded so D is wrong. Since variance is not checked anova is not right. Independence is not checked so E is wrong. Regression is wrong because there is no estimate for regression line here
B) is right.
Answer:
The team looses 16 people/audience with each loss.
Step-by-step explanation:
When the team had lost eight games, 295 people attended the next game.
When the team had lost 12 games, 231 people attended the next game.
Slope = 
= 
= -16
Therefore, the team looses 16 people/audience with each loss.
And the attendance loss is 16 times as great as the number of games lost/losses.
Answer:
1. Distance from Katie's House to the beach = 75 km
2. Hours that it takes to get to the beach = 6 hrs
3. -12.5 which tells us the rate at which katie traveled which was 12.5 km per hour
Steps to 3.
Rise/Run = -75/6 = -12.5 = slope
Answer:
60
Step-by-step explanation:
m(ADB) + m(BDC) = 90°
(3x+9) + (2x -4) = 90°
5x + 5 = 90°
5x = 85
5x/5 = 85/5
x = 17
m(ADB) = 3x + 9
3.17 + 9 = 51 + 9 = 60
Hope this helps ^-^
