2)WX=XU=5
In the given rhombus TUVW
TW=8(Given)
WX=5(Given)
What is a rhombus?A rhombus is a quadrilateral whose four sides all have the same length.
As we know that diagonals of the rhombus intersect at a right angle
So, by Pythagoras' theorem
[tex]TW^2 = TX^2 + WX^2\\8^2=TX^2 + 5^2\\TX = \sqrt{39}[/tex]
We know that the diagonals of a rhombus bisect each other
So XV =√39
Similarly, XU=WX =5.
Therefore, in the given rhombus TUVW
1)TX=XV=√39
2)WX=XU=5

Answers
Answer:
180000
Step-by-step explanation:
Answer:
180.000 m^2.
Step-by-step explanation:
Area in square kilometers
= 0.45 * 0.4
= 0.18
There 1000* 1000 = 1,000,000 square meters in a square kilometer so
Area in sq meters = 0.18 * 1000000
= 180,000 m^2.

Erin is 3 years younger than twice Alex's age. Their ages combined are 33 years. How old are Alex and Erin? Write a systems of equations first, let x=Erin's age and y=Alex's age
Answers
33-3=30 30/2=15 15+3=18 18+15=33
Answer:
X = 15 = Erin's age
Y = 18 = Alex's age
Step-by-step explanation:
X = Erin's age
Y = Alex's age
33 (combined ages) - 3 (how many years Erin is younger than Alex) = 30
30 ÷ 2 = 15
15 + 0 = 15 (Erin's age)
15 + 3 = (Alex's age)
X = 15 = Erin's age
Y = 18 = Alex's age
Check if I'm correct:
15 + 18 = 33

Suppose you had a population of fish whose lengths were normally distributed with a mean of 50 centimeters and a standard deviation of 5 centimeters. You draw a simple random sample of size 10, record the length of each fish, and calculate the mean of the sample lengths. What do you think your sample mean would most likely be
Answers
Answer:
The sample mean would most likely be 50 centimeters.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
In this question:
The mean of the population is 50 centimers.
So, by the Central Limit Theorem, the sample mean would most likely be also 50 centimeters.

Answers
Answer:
Tracey paid 34.5% of the original price.
Explanation
Tracey paid $190 for an item that was originally priced at $550.
For finding the percentage, first we need to divide the paid amount by the original price and then multiply the result by 100%
So, the percentage 190/500 x 100 % = 34.5% (Rounded to the nearest tenth)

How many judges should be selected to estimate the population mean wage with 90% confidence and a margin of error of $2.00
Answers
Answer:
The number of judges that should be selected is 25
Step-by-step explanation:
Given that:
The C.I = 90%
Level of significance = 1 - C.I
= 1 - 0.90
= 0.10
Critical level for [tex]Z_{\alpha/2}[/tex] at 0.10 = 1.645
The margin of error E = 2.00
Let's assume that the sample standard deviation was $6.11
Then;
The number of judges that should be selected can be computed by using the formula:
[tex]E = Z_{\alpha/2} \times \dfrac{s}{\sqrt{n}}[/tex]
[tex]2 = 1.645 \times \dfrac{6.11}{\sqrt{n}}[/tex]
[tex]2\sqrt{n} = 10.05095[/tex]
[tex]\sqrt{n} = \dfrac{10.05095}{2}[/tex]
[tex]\sqrt{n} =5.026[/tex]
[tex]n=(5.026)^2[/tex]
n = 25.26

A tunnel has a semicircular cross-section
and a diameter of 10 m. If the roof of a bus
just touches the roof of the tunnel when
the bus is 2 m from one side, how high is
the bus?
this question is from the IGCSE maths student book1, shape and space 2 for Edexcel
Answers
Answer:
Height of bus = 4 m
Step-by-step explanation:
I have attached an image showing the cross section of this tunnel.
Since the diameter is given as 10m.
Thus, radius = 10/2 = 5 m
Since radius is 5 m, it means that the distance from the center of the circle to the tunnel edge = 5 m
If the bus is 2 m from one side, it means that the centre of the road to the right hand side of the bus will be;
5 - 2 = 3 m
Looking at the image and our values here, it is clear that, the distance from the centre of the road to the point where the bus just touches the roof tunnel = 5
Using Pythagoras theorem, we can find the height of the bus, h;
h² + 3² = 5²
h² + 9 = 25
h² = 25 - 9
h² = 16
h = √16
h = 4 m

A store receives a shipment of 320 skateboard wheels. After 3 days, 272 of the skateboard wheels are left. After 7 days, 208 skateboard wheels are left.
a. Write an equation that represents the number y of skateboard wheels remaining after x days.
b. Use the linear equation to predict how many skateboard wheels will be left after 11 days.
c. After how many days should the store plan to receive a new shipment of skateboard wheels so they do not run out?
d. What does the slope of the equation represent? What does the y-intercept represent?
Answers
Answer:
[tex]y=-16x+320[/tex]

Change of the number of skateboards with respect to the change of days.
y intercept represents the total stock of the skateboard wheels.
Step-by-step explanation:
The points on the plane are [tex](3,272)[/tex] and [tex](7,208)[/tex].
Slope is given by
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{208-272}{7-3}\\\Rightarrow m=-16[/tex]
The equation of the line will be
[tex]y-y_1=m(x-x_1)\\\Rightarrow y-272=-16(x-3)\\\Rightarrow y-272=-16x+48\\\Rightarrow y=-16x+320[/tex]
The equation that represents the situation is [tex]y=-16x+320[/tex]
When the number of days is 11 we have [tex]x=11[/tex]
[tex]y=-16\times 11+320\\\Rightarrow y=144[/tex]
The number of wheels left after 11 day is 144.
When the shipment will run out [tex]y=0[/tex]
[tex]0=-16x+320\\\Rightarrow x=\dfrac{320}{16}\\\Rightarrow x=20[/tex]
So, after 20 days the shipment will run out.
The slope represents the change of the number of skateboards with respect to the change of days.
The y intercept represents the total stock of the skateboard wheels.

Earning an A in algebra this semester is an example of (A) a long term goal.
One of the many branches of mathematics is algebra, which means "reunion of shattered pieces, setting of bones" in Arabic. Algebra, which is a common thread throughout practically all of mathematics, is essentially the study of mathematical symbols and the rules for using them in formulas.
Since all mathematical applications involve manipulating variables as though they were numbers, elementary algebra is a prerequisite. The study of algebraic structures like groups, rings, and fields is referred to as abstract algebra, primarily in educational contexts (the term is no more in common use outside educational context). Modern presentations of geometry include linear algebra, which deals with linear equations and linear translations, and has numerous real-world applications (in weather forecasting, for example).Since there are a wide variety of application for Algebra in our day-to-day lives and in the modern sciences, so a good score in Algebra will not only get a good score for the results but also help learn valuable information for the future. Hence it is a long-term goal.
