1 answer:

4 0

<h3> $SI = \frac{PRT}{100} \\ = \frac{300 \times 7 \times 2}{100} \\ = 3 \times 7 \times 2 \\ = 21 \times 2 \\ = 42$ </h3>

$300 + $42 = $ 342

<h3>$ 342 is answer</h3>

In Exercise sketch the graph of the function.<br> f(x) = e - 2x + 1

Rus_ich [418]

Answer:

Attached linear graph

Step-by-step explanation:

The value of e is a mathematical constant of 2.72 approximately. We can consider this a constant as 1. Therefore this is a straight line with a gradient/slope of -2 and a y-intercept of:

$y=1+e=1+2.72=3.72$

and x intercept of:

$0=-2x+3.72$

$-3.72=-2x$

$x=1.86$

One of the events in the Winter Olympics is the Men's 500-meter Speed Skating.

Answer:

Mean: $\bar x = 40.61$

$Median =40.2$

$Mode = 43.4$

Step-by-step explanation:

Given

See attachment for data

Solving (a): The mean

Mean is calculated as:

$\bar x = \frac{\sum x}{n}$

From the attached:

$n = 14$

So, the mean is:

$\bar x = \frac{43.4+43.4+43.4+43.1+43.2+40.2+40.2+40.1+40.3+39.44+39.17+38.03+38.19+36.45}{14}$

$\bar x = \frac{568.58}{14}$

$\bar x = 40.61$

Solving (b): The median

$n = 14$ ; this is an even number. So, the median is:

$Median = \frac{1}{2}(n+1)$

$Median = \frac{1}{2}(14+1)$

$Median = \frac{1}{2}(15)$

$Median = 7.5th$

This implies that the median is the average of the 7th and 8th item.

Next, is to order the data (in ascending order): <em>36.45, 38.03, 38.19, 39.17, 39.44, 40.1, 40.2, 40.2, 40.3, 43.1, 43.2, 43.4, 43.4, 43.4.</em>

The 7th and 8th items are: 40.2 and 40.2

The median is:

$Median = \frac{1}{2}(40.2 + 40.2)$

$Median = \frac{1}{2}*80.4$

$Median =40.2$

Solving (c): The mode

43.4 has the highest number of occurrence.

So:

$Mode = 43.4$
