Answer: The stem-and-leaf plot is shown below in the attached image.

=============================================================

Explanation

The given data set is:

40, 27, 17, 43, 47, 33, 26, 58, 49, 48, 35

64, 61, 54, 74, 43, 83, 61, 57, 34

Let's sort the values from smallest to largest

17, 26, 27, 33, 34, 35, 40, 43, 43, 47, 48, 49, 54, 57, 58, 61, 61, 64, 74, 83

The stems are the tens digit of each value. The stems used are: 1, 2, 3, 4, 5, 6, 7, and 8. The stems will go along the first column (along the left side) in the table.

The leaves represent the units digit of each value.

For example, the value 47 has a stem of 4 and a leaf of 7. At the top or bottom of your stem-and-leaf plot, you could have a key that says "4 | 7 means 47". The vertical line indicates the separation of stem and leaf.

For each stem row, sort the leaves from smallest to largest. You should get what you see in the table below. The horizontal spacing between each leaf is optional, and I find it's handy to easily read that portion of the table. Though your teacher or math book may remove those spaces entirely.

Also optional are horizontal grid lines to separate the stems.

What is the volume of the following rectangular prism?<br><br><br><br><br> Volume =_____units^3

Ber [7]

The formula of a volume of a rectangular prism:

$V=BH$

B - area of a base

H - height

The green rectangle is the base.

We have:

$B=3\dfrac{1}{3}=\dfrac{3\cdot3+1}{3}=\dfrac{10}{3}$

and

$H=1\dfrac{2}{5}=\dfrac{1\cdot5+2}{5}=\dfrac{7}{5}$

Substitute:

$V=\dfrac{10\!\!\!\!\!\diagup^2}{3}\cdot\dfrac{7}{5\!\!\!\!\diagup_1}=\dfrac{14}{3}=4\dfrac{2}{3}$

<h3>Answer: The volume of the following rectangular prism</h3><h3> is 4 2/3 u³.</h3>

On a cold day, hailstones fall with a velocity of 2i − 6k m s−1 . If a cyclist travels through the hail at 10i m s−1 , what is t

Paraphin [41]

Answer:

The velocity of the hail relative to the cyclist is $V_{hc}=-8\hat{i}-6\hat{k}$

The angle at which hailstones falling relative to the cyclist is $\theta = 36.86^\circ$

Step-by-step explanation:

Given : On a cold day, hailstones fall with a velocity of $2\hat{i}-6\hat{k}\text{ m/s}$ . If a cyclist travels through the hail at $10\hat{i} \text{ m/s}$ .

To find : What is the velocity of the hail relative to the cyclist and At what angle are the hailstones falling relative to the cyclist?

Solution :

The velocity of the hailstone falls is $V_h=2\hat{i}-6\hat{k}\text{ m/s}$

The velocity of the cyclist travels through the hail is $V_c=10\hat{i} \text{ m/s}$

The velocity of the hail relative to the cyclist is given by,

$V_{hc}=V_h-V_c$

Substitute the value in the formula,

$V_{hc}=2\hat{i}-6\hat{k}-10\hat{i}$

$V_{hc}=-8\hat{i}-6\hat{k}$

So, The velocity of the hail relative to the cyclist is $V_{hc}=-8\hat{i}-6\hat{k}$

Now, The angle of hails falling relative to the cyclist is given by

$\theta = \tan^{-1}(\frac{-6}{-8})$

$\theta = \tan^{-1}(\frac{3}{4})$

$\theta = 36.86^\circ$

So, The angle at which hailstones falling relative to the cyclist is $\theta = 36.86^\circ$

The support of a wood table are in the shape of a right triangle. Find the third angle of the triangle of the measure of one of

Semenov [28]

<h3>The measure of third angle of triangle is 67 degrees</h3>

<em><u>Solution:</u></em>

Given that,

The support of a wood table are in the shape of a right triangle

Since it is a right angle, one of the angle must be $90^{\circ}$

The measure of one of the angles is 23 degrees

To find: third angle angle

We know that,

Sum of all angles in triangle equals 180 degrees

Therefore,

$90^{\circ} + 23^{\circ} + \text{ third angle } = 180^{\circ}\\\\ \text{ third angle } + 113 = 180\\\\ \text{ third angle } = 180 - 113\\\\ \text{ third angle } = 67^{\circ}$

Thus measure of third angle of triangle is 67 degrees
