A coordinate grid with 4 lines. Line A passes through (0, 5) and (4, 3.75). Line B passes through (3.75, 0) and (0, negative 5).

Line C passes through (0, negative 5) and (negative 3.75, 0). Line D passes through (negative 3.75, 0) and (0, 5).

First, you should make a graph plotting "h" as the y-axis and "t" as the x-axis. Then, you can plot the equation they give you in the question.

Part A is asking about the slope of the graph. Basically, you need to find the rise over the run each second.

Part B is asking about the "h"-intercept, or the y-intercept. When Johnny first began his ride, exactly 0 seconds passed, and he was at the top of the hill.

Part C is asking you to find how long it will take to travel a third of the way down the hill. (I think the answer should be 5 seconds, but I'll leave it to you to figure out why.)

Answer:

Following are the responses to the given choice:

Step-by-step explanation:

For point a:

H_0: \mu_1 - \mu_2 = 0\\\\ H_1: \mu_1 - \mu_2 < 0

For point b:

t = -2.953

For point c:

\to  p- value = 0.0021

For point d:

Reject H_o. It could deduce that the pay of higher banking is considerably lower than the pay of higher project management.

Use sigma notation to represent the sum of the first six terms of the following sequence: −10, −13, −16, …
SSSSS [86.1K]

Sigma notation of sequence −10, −13, −16, … is \sum_{n=1}^{6}-(3 n+7)

<h3><u>Solution:</u></h3>

Need to determine the sigma notation for the following sequence  

−10, −13, −16, …

Let's try to build a generic formula for given sequence  

The given sequence is in Arithmetic progression where first term = -10 and common difference = -3

<em><u>The formula for arithmetic progression is given as:</u></em>

a_n = a_1 + (n - 1)d

Where,

a_n is the nth term in the sequence

a_1 is the first term in the sequence

d is the common difference between the terms

Here in this sequence a_1 = -10 and d = -3

a_n = -10 + (n - 1)(-3)\\\\a_n = -10 - 3n + 3\\\\a_n = -3n - 7

So generic formula for a term is – ( 3n + 7 )

\begin{array}{l}{\text { For } \mathrm{n}=1, \text { term is }-(3 \times 1+7)=-10} \\\\ {\text { For } \mathrm{n}=2, \text { term is }-(3 \times 2+7)=-13} \\\\ {\text { For } \mathrm{n}=3, \text { term is }-(3 \times 3+7)=-16}\end{array}

And so on

<em><u>Using sigma notation for arithmetic sequence:</u></em>

\sum_{k=1}^{n} a_{k}

So for first six terms value of n will vary from 1 to 6 and in sigma notation it can be represented as

\sum_{n=1}^{6}-(3 n+7)

see which one yields a bigger "pymt" figure
