Determine the perimeter of the composite figure.
Answer:
50.26 if you use 3.14 for pi
50.35 if you use 3.15 for pi
Step-by-step explanation:
First, we find the circumference of the circle in the center.
(15 - 3 - 3)/2 = 4.5
4.5 is the radius
Equation for circumference: 2*pi*r
2*pi*4.5
9pi
Depending on where you normally use 3.14 or 3.15 for pi changes the answer but for this example I will use 3.14
The circumference of the circle is 28.26
Next, add the other sides of the figure.
28.26 + 3 + 3 + 3 + 3 + 5 + 5 = 50.26
One number is three less than two times another number. If the sum of the numbers is 15, find the numbers
9514 1404 393
Answer:
6, 9
Step-by-step explanation:
Let x represent one of the numbers. Then the other number is 15-x (because their sum is 15). The relation between the numbers is ...
2x -3 = 15 -x . . . . . three less than twice one number is the other number
3x = 18 . . . . . . add 3+x
x = 6 . . . . . . divide by 3
15-x = 9 . . . . find the other number
The two numbers are 6 and 9.
three letters are selected from the word DISPLAY how many different combination are there
Answer:

Here, all the 7 letters are different, thus the combination of selecting three letters from the 7-letter word (DISPLAY) can be given as,
[tex]^7C_3=\dfrac{7\times6\times5}{3\times2\times1}\\[/tex]
[tex]^7C_3=35[/tex]
Thus the number of combination of selecting three letters from the 7-letter word (DISPLAY) are 35.

.Let's say you solve an equation like 3x + 5 = x + 7 and your solution is x = 1. How could you check to make sure your answer is correct?
Answer:
plug in whatever you found for x and see if its equal on both sides.
Step-by-step explanation:
Answer:
To check an answer for an equation, you can substitute the answer you've found in place of the variable you solved it for.
The value of the unknown, x, can be plugged into the equation. You can then compare both sides to see if they are equal.
For your given equation, let's substitute 1 for x in the equation you've given.
3x + 5 = x + 7
3(1) + 5 = 1 +7
Simplify this.
3 + 5 = 8
8 = 8
You know that 8 does equal 8, so your value for x is correct.
I hope this helps you ^^

The stock of Company A lost $0.91 throughout the day and ended at a value
of $51.09. By what percentage did the stock decline?
Answer:
1.75
Step-by-step explanation:
just check and that person was wrong
Answer: 1.75%
Step-by-step explanation: new value: $51.09
51.09+0.91=\$52.00
Old value: 51.09+0.91=$52.00
52(1-r)=51.09
52(1−r)=51.09
{52(1-r)}{52} ={51.09}{52}
52
52(1−r)

A random sample of 9th-grade students was asked if they prefer taking notes on a computer or using a paper and pencil. Of the 180 students who were surveyed, 75 said they preferred using the computer. The resulting 99% confidence interval for the proportion of students who prefer taking notes on the computer was (0.322, 0.511). The school newspaper ran a story saying that less than half of the student body prefers taking notes on a computer. Based on the interval, is the newspaper justified in this statement?
Answer:
NO
Step-by-step explanation:
since the interval contains values above 0.5, it is plausible that more that 50% of students prefer using a computer for notes.
Using the given confidence interval, since it's upper bound is above 50%, the newspaper is not justified in this statement.
What is the interpretation of a x% confidence interval?It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b.
Hence, in this problem, we are 99% confident that the proportion is between 0.322 and 0.511. Since the upper bound of the interval is above 50%, there is not enough evidence to say that the proportion is below 50%, hence the newspaper is not justified in this statement.
