15/2
Step-by-step explanation:
Hello,
the area of a triangle is b*h/2
we can set BC as the base because AC is harder to calculate.
Then we draw an imaginary height.
There's no way to really explain, but the height would be 5 here, since 3 - -2 = 5
The base is 3
3*5/2 = 15/2
Thanks,

In sample of 200 economists, 147 choose the FRED database as the most popular economic database. Calculate the margin of error for a 97% confidence interval.
Answers
Answer: 0.9577
Step-by-step explanation:
Formula for margin of error (E):
[tex]E= z^*\sqrt{\dfrac{p(1-p)}{n}}[/tex] , where p = sample proportion, n =sample space, z* critical z-value.
Given: n= 200
[tex]p=\dfrac{147}{200}[/tex]
Critical value for 97% confidence level = 2.17
Margin of error (E) = [tex]2.17\sqrt{\dfrac{147}{200}(1-\dfrac{147}{200})}[/tex]
[tex]=2.17\sqrt{\dfrac{147}{200}(\dfrac{53}{200})}\\\\=2.17\times \sqrt{0.194775}\\\\=2.17\times0.441333207452\approx0.9577[/tex]
Hence, the margin of error for a 97% confidence interval = 0.9577

Answer:
Step-by-step explanation:
First, expand out the brackets
2 x 1.6a = 3.2a
2 x 0.7 = 1.4
Therefore 3.2a - 1.4 = 8.2
Now solve to find a
3.2a - 1.4 = 8.2
3.2a = 9.6
a = 3

A total of 937 people attended the play. Admission was $2.00 for adults and $0.75 for students. The total ticket sales amounted to $1,109. How many students and adults attended the school play? First complete the equations below, where A stands for Adults and S stands for Students. 2A + 0.755 = 1,109; A + S = 937 Now use the equations to find the number of students and adults. Students = [?]; Adults = [ ]
Answers
Answer:
612 students and 325 adults.
Step-by-step explanation:
To determine the number of adults and students who attended the event, knowing that in total there were 937 people who spent a total of $ 1,109 and that each student ticket is worth $ 0.75 while each adult ticket is worth $ 2, the following logical reasoning must be performed:
2 - 0.75 = 1.25
Therefore, the minimum that each ticket will be worth is $ 0.75, while there will be a surplus of money that will be divisible by 1.25, which is the amount of more that each adult paid on their ticket.
Therefore, since 0.75 x 937 equals 702.75, the total price surplus is 406.25 (1,109 - 702.75). Now, this number divided by 1.25 gives a total of 325, with which 325 adults attended the event. In turn, given that the total number of attendees was 937, the total number of students who attended the event is 612 (937 - 325).

Answer:
15²+40²=42.72
Step-by-step explanation:
In this particular problem, you can use pythagorean theorem. The pythagorean theorem consists of the formula a²+b²=c². This theorem is mostly used when solving for the hypotenuse in a right triangle.
In this problem,
a=15
b=40
c=? (this is the hypotenuse)
then, plug the numbers into the formula
a²+b²=c²
15²+40²=?
15²=225
40²=1600
1600+225=1825
or you could just punch the numbers in a calculator
then take the square root of 1825 to find your answer
√1825=42.72

Find an equation of the line with the given y-intercept and slope m.
3.2, m = -2.4
The equation of the line is
(Type your answer in slope-intercept form.)
Answers
Answer:
y = -2.4x + 32
or y = -12/5x + 16/5
or 12x + 5y = 16
Step-by-step explanation:
slope intercept form is y = mx + b
replace the m with the slope and b with y intercept
y = -2.4x + 3.2
with fractions instead of decimals its
y = -12/5x + 16/5
you could also write it like this I think
12x + 5y = 16
whatever way you were taught, do it

A. The mean is all of the numbers added together, and divided by how many numbers there are, so take all of the numbers, which end up being added up to 97, and then divide by 15, because that´s how many numbers there are, you end up getting 6.46666 and you round it to 6.466
B. The median is when you take all of the numbers and put them into order, and then find the number in the exact middle of all of the numbers, so the numbers were 4 5 5 5 5 5 5 6 6 7 7 8 8 9 12, the middle number was 6
C. The mode is the number that appears the most, and that would be 5
D. The most reccuring number is 5, and if you take that and multiply it by how many times it is shown, 6, you get 30

A cylindrical tube 9.5 cm high and 0.85 cm in diameter is used to collect blood samples. How many cubic decimeters (dmଷ ) of blood can it hold (V = πrଶh)?
Answers
Answer: 0.539 cubic decimeters of blood can be hold by the cylinder.
Step-by-step explanation:
Volume of cylinder= volume of blood it can hold = [tex]\pir^2h[/tex]
Given :
Height of cylinder (h) = 9.5 cm
Diameter of cylinder (d) = 0.85 cm
Thus radius of cylinder (r) = [tex]\frac{\text {Diameter of cylinder}}{2}=\frac{0.85cm}{2}=0.425cm[/tex]
Putting the values we get:
Volume of cylinder= volume of blood it can hold = [tex]3.14\times (0.425cm)^2\times 9.5cm=5.39cm^3=0.539dm^3[/tex] [tex] (1cm=0.1dm)
Thus 0.539 cubic decimeters of blood can be hold by the cylinder.
The measurements of 100 products from the assembly line show that 99% are correct. Is this percentage a parameter or a statistic and why
Answers
Answer:
The percentage is a statistic, because it is a mesure of the sample.
Step-by-step explanation:
The difference of statistic and parameter is given by:
Statistic is a measure of the sample.
Parameter is a measure of the population.
In this question, we have that:
The measurements of 100 products from the assembly line show that 99% are correct.
This is the percentage from a sample of 100 products, not from an entire population, so the percentage is a statistic.

Given:
y = -3x + 5
5x - 4y = -3
Since we are given y, let’s sub it in the second equation.
5x - 4(-3x + 5) = -3
5x + 12x - 20 = -3
17x = 17
x = 1
After finding x, we can now find y.
5(1) - 4y = -3
-4y = -8
y = 2
Checking:
y = -3x + 5
2 = -3(1) + 5
2 = 2
5x - 4y = -3
5(1) - 4(2) = -3
