Answer: 12.8 meters long
Step-by-step explanation:
b=body length
8/1=b/1.6
8=b/1.6
b=12.8 meters long
Considering the p-value, the decision is described as follows:
Since the p-value is less than , we reject .
<h3>What is the relation between the p-value and the conclusion of the test hypothesis?</h3>
Depends on if the p-value is less or more than the significance level:
- If it is more, the null hypothesis is not rejected.
- If it is less, it is rejected.
In this problem, we have that:
- The p-value is of 0.0739.
- The significance level is of 0.1.
Hence:
Since the p-value is less than , we reject .

Answer:
Option B. is the answer.
Step-by-step explanation:
The given question is incomplete; complete question has been given in the picture attached.
Current in the circuit at the time t is .
Power delivered to the resistor is
Where R = resistance
We have to express the power in the terms of cos2w.
Since formula to get the power in a circuit with resistance R and current I is given by
P = I²R
Therefore, power for the given circuit will be
P =
P = [Since sin²t = ]
P =
Therefore, Option B. will be the answer.
Answer:x = 7
x = 2
Step-by-step explanation:
The first term is, x2 its coefficient is 1 .
The middle term is, -9x its coefficient is -9 .
The last term, "the constant", is +14
Step-1 : Multiply the coefficient of the first term by the constant 1 • 14 = 14
Step-2 : Find two factors of 14 whose sum equals the coefficient of the middle term, which is -9 .
-14 + -1 = -15
-7 + -2 = -9 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -7 and -2
x2 - 7x - 2x - 14
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-7)
Add up the last 2 terms, pulling out common factors :
2 • (x-7)
Step-5 : Add up the four terms of step 4 :
(x-2) • (x-7)
Which is the desired factorization
