Stels [109]

Answer:

a) 0.1535

b) 0.4866

c) 0.8111

Step-by-step explanation:

The probability that the next call come within the next t minutes is:

$p(t) = 1 -e ^{- t/3}$

According to this model,

a) the probability that a call in comes within 1/2 minutes is $p(t) = 1 -e ^{- (1/2)/3}$ =0.1535

b) the probability that a call in comes within 2 minutes is $p(t) = 1 -e ^{-2/3}$ =0.4866

c) the probability that a call in comes within 5 minutes is $p(t) = 1 -e ^{-5/3}$ =0.8111

N76 [4]

Answer:

The dog biscuits are approximately 69% off.

Step-by-step explanation:

(1 - 0.69/2.23) * 100

(223/223 - 69/223) * 100

154/223 * 100 = 69%

Select the correct answer. Using synthetic division, find (2x4 + 4x3 + 2x2 + 8x + 8) ÷ (x + 2). A. B. C. D.

Mamont248 [21]

Step-by-step explanation:

If you use synthetic division, you get,

$2x {}^{3} + 2x + 4 + \frac{0}{x + 2}$

Which is,

$2x {}^{3} + 2x + 4$

Find the pattern and use it to list the nth term in the sequence.<br> 3, 9, 27, 81, 243 ...

KonstantinChe [14]

The pattern is formed a geometric sequence

The nth term of the sequence is $a_{n}=3^{n}$

Step-by-step explanation:

The formula of the nth term of a geometric sequence is:

$a_{n}=ar^{n-1}$ , where

a is the first term
r is the common ratio between the consecutive terms

∵ The pattern is 3 , 9 , 27 , 81 , 243

∵ 9 ÷ 3 = 3

∵ 27 ÷ 9 = 3

∵ 81 ÷ 27 = 3

∵ 243 ÷ 81 = 3

- There is a common ratio 3 between each two consecutive terms

∴ The pattern is formed a geometric sequence

∵ The first term is 3

∴ a = 3

∵ The common ratio is 3

∴ r = 3

- To find the nth term substitute a and r in the formula above

∵ $a_{n}=ar^{n-1}$

∴ $a_{n}=3(3)^{n-1}$

- Remember we add the powers of the same base with multiplication

∵ 3 × $3^{n-1}$ = $3^{1+n-1}$

∴ 3 × $3^{n-1}$ = $3^{n}$

∴ $a_{n}=3^{n}$

∴ The nth term of the sequence is $a_{n}=3^{n}$

dezoksy [38]

Answer:

Given:

v = 150d

v represents company's production for the coming year

d represents the number of days

150 is the daily production

The rate of change of the function representing the number of vehicles manufactured for the coming year is CONSTANT (150) , and its graph is a STRAIGHT LINE . So, the function is a LINEAR function.
