how do you Calculate the area of a missing square.
Answer: Option D
Step-by-step explanation:
Hey there!
Here; Looking at it we can state that it is a Right angled triangle.
And must use the Pythagoras relation if the triangle is a Right angled triangle.
So, let's work on it.
Let ABC be a triangle.
Taking reference angle as C, we get;
perpendicular= 3m
Hypotenuse= 7m
Base = xm
Now;
[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]
[tex]or \: b = \sqrt{ {h}^{2} - {p}^{2} } [/tex]
Put all values.
[tex]b = \sqrt{ {7}^{2} - {3}^{2} } [/tex]
Simplify to get answer.
[tex]b = \sqrt{49 - 9} [/tex]
[tex]b = \sqrt{40} [/tex]
Therefore, X= 6.3m.

a furniture company currently produces 5800 chairs per month. If production decreases 5%, find the amount of the decrease and the new number of chairs produced each month.
Answer:amount of decrease 290 ;numbers of chairs 5510
Step-by-step explanation:
Stablish the proportion 5800/100%=x/5% then solve for x. ; x=(5%/100%)*5800 = 290 which is the decrease. Then make the difference 5800-290 and you get 5510
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
The number of chairs decreased is 290.
The number of new chairs produced each month is 5510.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Number of chairs produce in a month = 5800
5% decrease in production:
= 5% of 5800
= 5/100 x 5800
= 5 x 58
= 290
The number of new chairs produced each month:
= 5800 - 290
= 5510
Thus,
The number of chairs decreased is 290.
The number of new chairs produced each month is 5510.

For which value of x does f(x) = 2
Answer:
x = -4Step-by-step explanation:
Look a the picture.
Draw the horizontal line y = 2.
Common point: (-4, 2).
Conclusion: f(x) = 2 → x = -4
From the graph at x = -4, then value of f(x) will be 2.
What is Graph?A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
In the given graph, first we have to draw a line f(x)=2 i.e y=2
Draw the horizontal line y = 2.
We have to check where the horizontal line is meeting the line in graph.
Then we get a Common point at (-4, 2).
So x value is =-4 for f(x)=2 in the given graph.

1. This composite figure is created by placing a sector of a circle on a rectangle. What is the area of this composite figure? Show you work.
Answer:
29.92 m² (nearest hundredth)
Step-by-step explanation:
[tex]\textsf{Area of a sector}=\dfrac{\theta}{360\textdegree}\pi r^2[/tex]
[tex]\implies \textsf{area}=\dfrac{30}{360\textdegree}\pi \cdot 5.5^2=\dfrac{121}{48}\pi \textsf{ m}^2[/tex]
Area of rectangle = width × length
⇒ area = 4 × 5.5 = 22 m²
Total area = area of sector + area of rectangle
⇒ total area = [tex]\dfrac{121}{48}\pi +22[/tex] = 29.91943148... = 29.92 m² (nearest hundredth)

At the us open tennis championship a statistician keeps track of every serve that a player hits during teh torunment. The statistcian reported that the mean serve speed of a particluar player was 101 miles per hour and teh standard deviation of the serve speeds was 11 mph. If nothing is known about the shape of distribution give an interval that will contain the speeds of at least eight ninths of the players serves
Answer:
68mph to 134 mph
Step-by-step explanation:
We apply
Chebyshev's Theorem States:
At least 3/4 or 75% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.
At least 8/9 or 88.89% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
From the question,
Mean = 101 miles per hour
Standard deviation = 11 miles per hour
We are to give an interval that will contain the speeds of at least eight ninths of the players serves
Hence, we apply the rule
At least 8/9 or 88.89% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
μ - 3σ
= 101 - 3(11)
= 101 - 33
= 68 miles per hour
μ + 3σ.
= 101 + 3(11)
= 101 + 33
= 134 miles per hour
Therefore, the interval is 68mph to 134 mph

What is the sum of the 2nd square number and the 4th cube number?
In a properly drawn sample with a 3-percent sample error, 20% of 100 respondents indicate they intend to vote for a ballot measure. This means that there is high probability that between ______ percent of all voters actually plan to vote for the ballot measure.
The true statement is that, the probability that 17% to 23% percent of all voters planned to vote is high
How to determine the probability?The percentage sample error (S) is given as:
S = 3%
The proportion (p) of the respondent is given as:
p = 20%
This means that the range (R) of the proportion is:
R = p ± S
This gives
R = 20% ± 3%
Expand
R = (20% - 3%, 20% + 3%)
Evaluate
R = (17%, 23%)
This means that the range is 17% to 23%

A. Multiply the top equation by 15 and the bottom equation by 7.
B. Multiply the top equation by 1/3.
O C. Multiply the top equation by 3 and the bottom equation by 4.
D. Multiply the top equation by-3 and the bottom equation by 2.
4x – 2y=7
3x – 3y = 15
we want to keep y by eliminating the x
so we will Multiply the top equation by 3 and the bottom equation by 4.
we will get
12x - 6y = 21
12x - 12y = 60
we subtract the equations
12x - 6y - 12x - (-12y) = 21 - 60
6y = -39 and so on
