Answer:

x = 12

Step-by-step explanation:

4x and 48 are corresponding angles and are congruent, then

4x = 48 ( divide both sides by 4 )

x = 12

Need help finding n forgot how to do this

andreyandreev [35.5K]

Answer:

$n = 3\sqrt{2}$

There are two best ways to solve this.

using cosine method:

$cos(n) = \frac{adjacent}{hypotenuse}$

$cos(60) = \frac{adjacent}{6\sqrt{2} }$

$adjacent,n = cos(60) * 6\sqrt{2}$

$n = 3\sqrt{2}$

using sine method:

$sin(n) = \frac{opposite}{hypotenuse}$

$sin(30)= \frac{n}{6\sqrt{2} }$

$n = sin(30) * 6\sqrt{2}$

$n = 3\sqrt{2}$

There are many ways, not to make it complex, these are the best ways to solve for n. Hope it helps ~

Ten experts rated a newly developed chocolate chip cookie on a scale of 1 to 50. Their ratings were: 34, 35, 41, 28, 26, 29, 32,

miskamm [114]

The mean deviation of the ratings is 4.12

Explanation

The ratings of the ten experts are: 34, 35, 41, 28, 26, 29, 32, 36, 38 and 40

So, the mean of all ratings $=\frac{34+35+41+28+26+29+32+36+38+40}{10}= \frac{339}{10}=33.9$

The formula for Mean deviation $= \sum \frac{|x_{i}- \mu|}{N}$ , where $x_{i}$ is the given data from $i=1$ to $i=10$ , $\mu$ is the mean of the data and $N$ is the total number of data. So.....

$|x_{1}-\mu |= |34-33.9|=0.1\\ |x_{2}-\mu|=|35-33.9|=1.1\\ |x_{3}-\mu |=|41-33.9|=7.1\\ |x_{4}-\mu |=|28-33.9|=5.9\\ |x_{5}-\mu |=|26-33.9|=7.9\\ |x_{6}-\mu |=|29-33.9|=4.9\\|x_{7}-\mu |=|32-33.9|=1.9\\ |x_{8}-\mu |=|36-33.9|=2.1\\ |x_{9}-\mu |=|38-33.9|=4.1\\ |x_{10}-\mu |=|40-33.9|=6.1$

So, the Mean deviation $=\sum \frac{|x_{i}-\mu |}{N}=\frac{0.1+1.1+7.1+5.9+7.9+4.9+1.9+2.1+4.1+6.1}{10} = \frac{41.2}{10}=4.12$

Find the meaure of the central angle the sector area is 169.56 and the radius is 9

BaLLatris [955]

Since the area of a circle is π $r^{2}$ , and our radius is 9 we know the total area to be 254.469, and the ratio of sector area to total area is 169.56/254.469 = .6663. There are 360 degrees in a circle, so: $c = 360(.6663)$ ≈ 240°

240 degrees

Two boys searching for buried treasure are standing underneath the same tree. one boy walks 12 m east and then 12 m north. the o

mylen [45]

Let
The origin of coordinates the tree
r1 = vector position of the child 1.
r2 = vector position of the child 2
Child 1:
r1 = (12i + 12j)
Child 2:
r2 = (-18i + 11j)
The scalar product will be given by:
r1.r2 = ((12) * (- 18)) + ((12) * (11)) = - 84
The scalar product of their net displacements from the tree is -84m ^ 2
