The first sequence rule is multiply by 3 starting from 5. The second sequence rule is add 9 starting from 18. What is the first
tatyana61 [14]

Considering the sequences given, the first number that appears in both sequences is given by: 45.

<h3>What numbers appear in the first sequence?</h3>

The rule is multiply by 3 starting from 5, hence the numbers are:

(5, 15, 45, 135, ...).

<h3>What numbers appear in the second sequence?</h3>

The rule is add 9 starting from 18, hence the numbers are:

(18, 27, 36, 45, ...).

45 is the first number that appeared in both sequences.

In 2003, the price of a certain automobile was approximately $32,000 with a depreciation of $1,740 per year. After how many year
IRINA_888 [86]

Answer:

The correct answer is 5 years i.e. 2008.

Step-by-step explanation:

Price of the automobile in 2003 is $32000.

Depreciation per year is given by $1740.

Therefore let the car value is depreciated for t number of years.

Value depreciated for t years is given by $ (1740t).

The final value of the car after t years is given to be $23300.

Thus the equation is given by 32000 - 1740t = 23300.

⇒ 1740t = 32000 - 23300

⇒ 1740t = 8700

⇒ t = 5

Thus after 5 years the value of the car is $23300.

Thus in 2008 the depreciated price of the car would be $23300.

I need help with A and B, any other ones you don't have to do (you can if you'd like to help me out XD)
fiasKO [112]

Answer:

Step-by-step explanation:

B)  S = {1,2,3,4,5,6}

n(S) = 6

B =  factors of 2 when rolling a single die = {1 , 2}

n(B) = 2

P(B} = \frac{2}{6}=\frac{1}{3}

A) n(S) = 50

A  = Picking numbers with 3 in tens place = {30, 31,32,33,34,35,36,37,38,39}

n(A)  = 10

P(A) = \frac{10}{50}=\frac{1}{5}

Using the z-distribution, the test statistic is:

c) -2.63.

<h3>What are the hypothesis tested?</h3>

At the null hypothesis we test if the means are equal, equivalent to a subtraction of 0, hence:

H_0: \mu_D - \mu_C = 0

At the alternative hypothesis, we test if they are different, hence:

H_1: \mu_D - \mu_C \neq 0

<h3>What are the mean and the standard error for the distribution of differences?</h3>

For each sample, they are given as follows:

  • \mu_D = 12, s_D = \frac{5.2}{\sqrt{73}} = 0.6086.
  • \mu_C = 14, s_C = \frac{4.1}{\sqrt{81}} = 0.4556.

For the distribution of differences, it is given by:

  • \overline{x} = \mu_D - \mu_C = 12 - 14 = -2.
  • s = \sqrt{s_D^2 + s_C^2} = \sqrt{0.6086^2 + 0.4556^2} = 0.76

<h3>What is the test statistic?</h3>

The test statistic is given by:

z = \frac{\overline{x} - \mu}{s}

In which \mu = 0 is the value tested at the null hypothesis.

Hence:

z = \frac{\overline{x} - \mu}{s}

z = \frac{-2 - 0}{0.76}

z = -2.63.
