Answer:
-1 1/2
Step-by-step explanation:
1.5 = 1 4/8 = 12/8
(-15/8 + 12/8) = -3/8
(15-14 3/4 = 1/4
-3/8 ÷ 1/4 = -3/8 × 4/1 = = -3/2 or -1 1/2

Point M is the midpoint of Ac. Find the coordinates of M. A(2, 3), C(6. 10)
Answer:
coordinates of M will be (4, [tex]\frac{13}{2}[/tex])
Step-by-step explanation:-
To find the coordinates of the midpoint, we can use this equation:-
[tex]\frac{x1 + x2}{2} , \frac{y1 + y2}{2}[/tex]
M is the midpoint of AC, where A is (2,3) and B is (6, 10)
So, x1 will be 2,
x2 will be 6
y1 will be 3
and y2 will be 10.
So, substituting these in the equation, we get:-
[tex]\frac{2 + 6}{2} , \frac{3+10}{2}[/tex]
[tex]\frac{8}{2} , \frac{13}{2}[/tex]
4, [tex]\frac{13}{2}[/tex]
So, the coordinates of the point M will be 4, [tex]\frac{13}{2}[/tex]
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.

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

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)
= 1.75%
