15+8x=2x+7-5x
Subtract 8x from both sides.
15=2x+7-5x-8x
Combine like terms.
15=-11x+7
Subtract 7 from both sides.
8=-11x
Divide -11 from both sides.
.73=x
Your answer is .72
Answer:
The correct option is a)
05; .73; .27 , type 1 error, type 11 error and the power of the test respectively.
Step-by-step explanation:
Alpha is the probability of a type 1 error, given the null hypothesis is true. Therefore alpha= 0.05
Type 11 error is the probability of accepting a false null hypothesis.
Beta= 0.73
The Power of a test is the probability of rejecting the null hypothesis, given it is false
Power= 1- beta
Power= 1-0.73
Power= 0.27
Therefore the type 1 error is 0.05
The type 11 error is= 0.73
The power of the test= 0.27
The right option is a)
Answer: N:-4,-2 M:-2,-1 P:-1,-4
Step-by-step explanation:
Answer:
Step-by-step explanation:
first piece= 1u
second piece= 3u
third piece=18 feet
maximum length for first+second piece= 100-18= 82
4u= 82
1u= 20.5
3u= 20.5x3= 61.5
<u><em>ANSWER: 61.5 feet</em></u>
Answer:
The perimeter is doubled.
Step-by-step explanation:
Let's pretend we have a triangle with side measurements p,q, and r.
The perimeter will be the sum of the side measurements of this triangle which is p+q+r.
If we decide to dilate the figure by a factor of 2, then we are multiply each side by 2. So the perimeter of the new triangle becomes 2p+2q+2r.
Factoring this gives us 2(p+q+r). The perimeter has doubled.
The same thing would happen if we look at a quadrilateral. There would be 4 measurements multiplied by 2 and you would factor out the 2 giving you 2(old perimeter) for the new perimeter of the dilated shape.
