ABCD is a rhombus, where m∠AED = 5x – 10. Use the properties of a rhombus to determine the value of x.
Question 6 options:
A) x = 16
B) x = 20
C) x = 5
D) x = –2
Answer:
Option b
Step-by-step explanation:
According to the property of rhombus at Centre it have 90°
So,
[tex](5x - 10) {}^{o} = 90 {}^{o} [/tex]
[tex]5x = 90 + 10[/tex]
[tex]5x = 100[/tex]
[tex]x = \frac{100}{5} [/tex]
[tex]x = 20[/tex]

Read the article below carefully and answer the question that follows.
On the morning of July 15, 2006, fourteen school buses were vandalized. The buses, property of Walt Whitman Middle School, were parked in the "bus barn" on campus. The vandals spray-painted the buses with pictures of dogs. Dogs happen to be the mascot of rival school Edgar Allan Poe Academy. This has led some to believe that some students from EAPA may be the culprits in the incident. Says the mother of one Walt Whitman student, "Oh, yeah, the [Edgar Allan] Poe [Academy] kids are definitely responsible. Those kids don't have any discipline, and they're still stewing over the loss of last week's football game." Police, however, say that they currently have no suspects.

Find the size of angle XYZ give your answer to 1 decimal place
Step-by-step explanation:
angle x=90°
xz=opposite
xy=adjacent
zy=hypotenuse
we neee to find acute angle
y°=(7/12)=0,58(3)
Applying the cosine ratio, CAH, the size of angle XYZ, to 1 decimal place is calculated as: 54.3°.
What is the Cosine Ratio?To solve a right triangle by relating the adjacent side to the hypotenuse, the cosine ratio is applied, which is: cos ∅ = adjacent/hypotenuse.
Given the parameters:
∅ = angle XYZHypotenuse = 12 cmAdjacent side = 7 cmApply the cosine ratio:
Cos (XYZ) = 7/12
Angle XYZ = cos^(-1)(7/12)
Angle XYZ = 54.3°

The travel-to-work time for residents in Ventura County is unknown. Assume the population variance is 39. How large should a sample be if the margin of error is 1 minute for a 93% confidence interval
Answer:
A sample size of 128 is needed.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1-0.93}{2} = 0.035[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].
So it is z with a pvalue of [tex]1-0.035 = 0.965[/tex], so [tex]z = 1.81[/tex]
Now, find the margin of error M as such
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population(square root of the variance) and n is the size of the sample.
How large should a sample be if the margin of error is 1 minute for a 93% confidence interval
We need a sample size of n, which is found when [tex]M = 1[/tex]. We have that [tex]\sigma = \sqrt{39}[/tex]. So
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
[tex]1 = 1.81*\frac{\sqrt{39}}{\sqrt{n}}[/tex]
[tex]\sqrt{n} = 1.81\sqrt{39}[/tex]
[tex](\sqrt{n})^2 = (1.81\sqrt{39})^2[/tex]
[tex]n = 127.8[/tex]
Rounding up
A sample size of 128 is needed.

17 = 9 + 2r
r = what
Answer:
r = 4
Step-by-step explanation:
17 = 9 + 2r subtract both sides by 9
8 = 2r divide both sides by 2
4 = r
Answer:
r=4
Step-by-step explanation:
You have to get r on one side so you subtract nine on both sides to get rid of it so 8=2r
then you divide 2 m both sides and r=4

Select the graph that represents the equation
Pls help help Im crying and i need help please im nevous please help me
Answer:
Look in step by step
Step-by-step explanation:
The way to read coordinates is to know these steps.
(#,#)
the first number is the x number which on the graph is the horizontal line and the second number is the y number which on the graph is vertical.
Theres also negatives which is the same thing but its on the lower side of the graph.
So now for example you take -4,-9.
To make it easy move the dot to the center or the (0,0) cords. Then follow the numbers. When you start on the zero cord you will look at the numbers, it says -4 so drag the dot 4 units to the left where the line says -4. Then drag it down 9 units so its on the cords. Hope this helps!!
Answer:
Ok so for (0,8 1/2), drag the dot from the middle, up to 8 but then move up a little bit more so it is between the 8 and 9. Next, for (-4, -9) drag one of the other dots to the -4 on the horizontal line, but then move it down to the -9 on the vertical line. And finally for (-6,5), you should put the last dot on the -6 on the horizontal line, but move it up five spaces until it is at the 5 on the vertical line.
I hope I was able to help you, if you still do not understand I will try to explain a little bit more.

The ages (in years) of a random sample of shoppers at a gaming store are given below: 12 19 23 14 20 16 21 18 14 19 What is the variance
Answer: the required variance is 11.6555
Step-by-step explanation:
Given data;
xi = 2 19 23 14 20 16 21 18 14 19
mean x" = 2+19+23+14+20+16+21+18+14+19 / 10
mean x" = 166 / 10 = 16.6
so;
X xi - x" (xi - x")²
12 -4.9 24.01
16 -0.9 0.81
23 6.1 37.21
13 -3.9 15.21
18 1.1 1.21
18 1.1 1.21
19 2.1 4.41
18 1.1 1.21
13 -3.9 15.21
19 2.1 4.41
Total 104.9
Variance = n_i=1∑(xi - x")² / n-1
Variance = 104.9 / 9
Variance = 11.6555
Therefore, the required variance is 11.6555

SURFACE AREA HOW TO DO SURFACE AREA
Answer:
You can watch khan academy and it will show you also
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
Solve for x and then determine the measure of the exterior angle.
Answer:
B
Step-by-step explanation:
This is a straight line which the interior and exterior angle, so they both must add up to 180 degrees.
180 - 60 = 120
120 = 4x + 20
100 = 4x

Change this radical to an algebraic expression with fractional exponents.
Answer:
[tex] a^{\frac{1}{3} [/tex]
Step-by-step explanation:
Given, [tex] \sqrt[3]{a} [/tex].
To change this radical, we would apply the rule of fractional exponents. (i.e. [tex] a^{\frac{x}{y}} = \sqrt[y]{a^x} [/tex]
Thus:
[tex] \sqrt[3]{a} = a^{\frac{1}{3} [/tex]

Step-by-step explanation:
Erin had $35 more than Angie who had 3 times as much money as Jacob. If they had $196 altogether, how much money did each have?
Answer:
$23
Step-by-step explanation:
let j be jacob"s money
Then angie is 3j, and Erin is 3j+35 so 7I
=161
j=23
Answer: Erin - $104; Angie - $69; Jacob - $23.
(please give me brainlest ❤️)
Step-by-step explanation:
JACOB has least amount of money, so let's say that he has :
x amount of money
ANGIE has 3 times more than jacob:
Angie has 3x
ERIN has $35 more money than Angie:
3x+35
their money together is $196, that means if we add all of their money, it will be equivalent of 196:
3x+35+3x+x=196
now lets find x value.
put all the xes on right side and all known numbers on left side.
i think u know that when it goes to another side it changes sign; for example - makes + and × makes /
3x+35+3x+x=196
7x=161
x=161/7
x=23
now plug x values for each kid:
so Jacob had x=23
Angie had 3x=3×23=69
and Erin had 3x+35=69+35= 104
lets check our answer:
23+69+104=196
196=196
so sum of their money really gives us $196.
