Completely factor 40^4 - 324.

Mathematics
1 answer:
Setler [38]3 years ago
3 0

Answer:

40^4 - 324 = 2,559,676

Step-by-step explanation:

First we need to factor the left side of the equation, which is 40 to the 4th power. 40*40*40*40 is 2,560,000, now we need to subtract 324 from it which is 2,559,676.

What multiplies to give you 108 and adds up to give you -31?
meriva
4 x 27  = 108 and 4 + 27 = 31... I don't think there is any pair of numbers that would equal -31. So the answer would be 4 and 27. Good luck! Hope this helped!!

Based on the table, which best predicts the end behavior
kotykmax [81]

Answer:

Third option.

Step-by-step explanation:

In the picture attached, the question is shown. There we can see that as x gets bigger (x → ∞), f(x) gets smaller (f(x) → -∞ ). On the other hand, as x gets smaller (x → -∞), f(x) gets bigger (f(x) → ∞ ).

Suppose a simple random sample of size nequals49 is obtained from a population with mu equals 78 and sigma equals 28.
VLD [36.1K]

Answer:

0.0735,0.0179,0.7026

Step-by-step explanation:

Given that a simple random sample of size nequals 49 is obtained from a population with mu equals 78 and sigma equals 28.

Sample size = 49

Population mean = 78

Population std deviation = 28

Std error of sample mean = \frac{\sigma}{\sqrt{n} } \\=4

a) \bar x: N(78, 4)

b) P(\bar x >83.8)\\=0.0735

(by converting to Z and finding value from Z table)

c) P (x overbar less than or equals 69.6 )​

=P(\bar x \leq 69.6)\\=0.0179

d) P (75.8 less than x overbar less than 88 )

=P(75.8

Please help and show work :) ​
Mila [183]

Answer:

MK = 14

Step-by-step explanation:

MK = ML + LK , substitute values

4x - 2 = 8 + x + 2

4x - 2 = x + 10 ( subtract x from both sides )

3x - 2 = 10 ( add 2 to both sides )

3x = 12 ( divide both sides by 3 )

x = 4

Thus

MK  = 4x - 2 = 4(4) - 2 = 16 - 2 = 14
