scoray [572]3 years ago

Step-by-step explanation:

cubing both sides (p+1)^3= (7)^3

=> p^3+1/p^3+ 3(p+1/p) = 343

=> p^3+ 1/p^3 + 3(7)= 343

=> p^3+1/p^3= 343-21

=> p^3+1/p^3= 322

hope it helps

34 packages are randomly selected from packages received by a parcel service. The sample has a mean weight of 25.9 pounds and a
Vlad1618 [11]

Answer:

24.6 < μ < 27.2

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.025 = 0.975, so z = 1.96

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.96\frac{3.8}{\sqrt{34}} = 1.3

The lower end of the interval is the sample mean subtracted by M. So it is 25.9 - 1.3 = 24.6 pounds.

The upper end of the interval is the sample mean added to M. So it is 25.9 + 1.3 = 27.2 pounds.

So the correct answer is:

24.6 < μ < 27.2

PLEASE HELP<br> Complete the table by computing the amount in the account at the end of each period.
skad [1K]

Answer:

See below

Step-by-step explanation:

  • Initial Principal P₀ = 1000
  • End of first period = 1000 + 1000*0.02/4 = 1005
  • End of second period = 1005 + 1000*0.02/4 = 1010
  • End of third period = 1010 + 1000*0.02/4 = 1015
  • End of fourth period = 1015 + 1000*0.02/4 = 1020

How do I find angles a, b, and c?
LenaWriter [7]
For angle A, you need to do 180-130 which is 50
for angle B, you need to do 180- 90 - 50 which is 40
for angle C, you need to do 180 - 60 - 40 which is 80

If you want me to explain you with further details with how exactly I got those answers and how I knew what to do, then ask me.

Your friend claims that when a polynomial function has a leading coeffcient of 1 and the coefficients are all integers , every p
sammy [17]

Using the rational root theorem, it is found that your friend is correct.

<h3>What is the rational root theorem?</h3>
  • It is a theorem that states that for a polynomial with integer coefficients, with q being the factors of the leading coefficient and p being the factors of the constant, every <u>possible rational root</u> is the format \frac{p}{q}.

In this problem:

  • The leading coefficient is 1, hence it's only factor is q = 1, thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct.
