As it can be seen in the figure above, the figure A'B'C' is bigger than ABC due to dilation.
If we are to measure the side AB, that would be 3. Also, we have A'B' measured to be 6 units.
The dilation factor is calculated by dividing the lengths of the corresponding sides. In this example that would be,
d = A'B' / AB = 6 / 3 = 2
ANSWER: 2
1) a. 15% decrease
2) a. $79.20
3) b. 14.3% increase
4) a. $4.68
#1 explanation:
1435 - 1220 = 215
215/1435 = 0.1498
0.1498 x 100 = 14.98 = 15%
#2 explanation:
220 x 0.6 = 132
220-132=88
88 x 0.1 = 8.8
88-8.8 = 79.2 $
#3 explanation:
32-28=4
4/28=0.1428
0.1428 x 100 = 14.28 = 14.3%
#4 explanation:
275 x 0.15 = 41.25
275-41.25 = 233.75
233.75 x 0.02 = 4.675 = 4.68 $
Answer:
C. If 75% of Americans still favor mandatory testing this year, then there is a 3% chance that poll results will show 72% or fewer with this opinion.
Step-by-step explanation:
Significance level or alpha level is the probability of rejecting the null hypothesis when null hypothesis is true. It is considered as a probability of making a wrong decision. It is a statistical test which determines probability of type I error. If the obtained probability is equal of less than critical probability value then reject the null hypothesis. In this question the sample of 1000 Americans is under test. It is the result of the poll that 75% still favor mandatory testing.
Answer:
We don't have the task, we need it to solw it.
Answer:
Nico, Raj and Sandra are correct
Step-by-step explanation:
we have
<em>Method 1</em>
Solve for x
That means ----> isolate the variable x
we have
Multiply by 5/2 both sides
subtract 6 both sides
<em>Method 2</em>
Solve for x
That means ----> isolate the variable x
we have
Multiply by 1/2 both sides
Multiply by 5 both sides
subtract 6 both sides
<em>Method 3</em>
Solve for x
That means ----> isolate the variable x
we have
Apply distributive property left side
subtract 2 both sides
Multiply by 5/2 both sides
therefore
Nico, Raj and Sandra are correct
