Given TU = 7.4. what is PS in OC? Round to the nearest tenth.
Answer:
3.7
Step-by-step explanation:
TU= 7.4
PS is half of TU, so we divide 7.4 by 2.
The value of the PS in OC will be 3.8 Phythogorous theorem is applied in the triangle PSC to solve the problem.
What is the definition of geometry?It is concerned with the geometry, region, and density of various 2D and 3D shapes.
Joining the point p to c, resulting in pc being the circle's radius and equal to CQ's radius.
Take a look at the PSC triangle now. In the right angle triangle, PSC apply phythogorous theorem.
PC²=PS²+SC²
(5.1)²=PS²+(3.4)²
26.01=PS²+11.56
PS²=26.01-11.56
PS=√(14.45)
PS=3.8
Hence, the value of the PS in OC will be 3.8

Step-by-step explanation:
Symmetric means one side looks the same as another side such as a square. It isn't symmetric because the other side doesn't have the same side as the other so it isn't bell shaped and isn't symmetric
[tex]\huge{\textbf{\textsf{{\color{navy}{An}}{\purple{sw}}{\pink{er}} {\color{pink}{:}}}}}[/tex]
B. Not symmetrical, not bell-shaped12. The 95% confidence interval for a population mean is between 6.3 and 7.7. What was the mean
of the sample and margin of error that led to this confidence interval?
Answer:
The mean of the sample was of 7 and the margin of error was of 0.7.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
The margin of error is the subtraction between the bounds divided by 2.
In this question:
Lower bound: 6.3
Upper bound: 7.7
Mean of the sample is the point estimate, so: (6.3+7.7)/2 = 7
Margin of error: (7.7-6.3)/2 = 0.7
The mean of the sample was of 7 and the margin of error was of 0.7.

What are the numbers of round and oval beads Kelsey purchased?
Answer:
Lesley purchased 1 oval bead and 4 round beands.
Step-by-step explanation:
Given that Lesley purchased 5 beads at a total cost of 80 cents, and the round beads cost 15 cents each, and the oval beads cost 20 each, to determine what are the numbers of round and oval beads Kelsey purchased, the following calculation must be performed :
5 x 0.20 + 0 x 0.15 = 1
4 x 0.20 + 1 x 0.15 = 0.95
2 x 0.20 + 3 x 0.15 = 0.85
1 x 0.20 + 4 x 0.15 = 0.80

Alyssa can complete a job in 12 minutes. If Miranda helps her, they can complete the job in 9 minutes. How long would it take Miranda to complete the job by herself? (In minutes.) Rate of work problem
Answer:
36 minutes
Step-by-step explanation:
The key is to get the same amount of time for each.
9 * 12 = 108
At 12 minutes per job,
in 108 minutes Alyssa could do
108/12 = 9 jobs
At 9 minutes per job,
Together in 108 minutes they could do
108/9 = 12 jobs
--------------------------
In 108 minutes Mirada does
12 - 9 = 3 jobs
108/3 = 36 minutes per job

Find all real solutions of the equation (x-5)^2-4=0 real solutions=?
Answer:
x = 7
x = 3
Step-by-step explanation:
(x - 5)² - 4 = 0
Take the (x - 5)² and foil it. By doing that, you're going to set them both against each other to multiply. The squared part means that (x - 5) is being multiplied by itself. Like so:
(x - 5) (x - 5)
Multiply the x by the x, the x by the -5, the -5 by x, and the -5 by -5.
The x times x would be x². The x times -5 would be -5x. The -5 times x would be -5x. And the -5 and -5 would be 25.
To put it in an equation: x² - 5x - 5x + 25 - 4
Simply the equation: x² - 10x + 21
Now that it's a quadratic equation, we can factor. Looking at the final term, the 21, we can find factors of 21 that add up to -10, which would be -7 and -3. They both multiply to a positive 21 and add up to a -10.
Taking this new information, we can split the equation up like so: (x -7), (x - 3)
Set both equations equal to 0.
So: x - 7 = 0
Add seven to both sides.
x = 7
x - 3 = 0
Add three to both sides
x = 3
Final Answer: x = 3, x = 7, both are real solutions

Step-by-step explanation:
The average rate of change from day 2 to day 10 is given by the slope of the line m =
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
The number of houses sold on day 2 is P
The number of houses sold on day 10 is Q
Let the first point be P ( 2 , 8 )
Let the second point be Q ( 10 , 2 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 2 - 8 ) / ( 10 - 2 )
Slope m = -6/8
m = -3/4
Therefore , the number of houses sold between day 2 and 10 is -3/4 houses per day
Hence , the slope is m = -3/4 houses per day
