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

Hope this helps! :)

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:

The answer is given by option c.

Step-by-step explanation:

Linear function:

The graphic of a linear function is a straight line.

In this question:

We have a straight line for x between -2 and 0, so in this interval the function is linear.

For x between 0 and 2, the function is a curved line, so not linear in this interval.

We also have a straight line for x between 2 and 4, so in this interval the function is linear.

So it is linear in the following intervals: -2 < x < 0, 2 < x < 4, so the answer is given by option c.

Answer:

Following are the solution to this question:

Step-by-step explanation:

Please find the complete question in the attached file.

In the given equation, when the point t=0

So,

[tex]\to r(0) = (3 \cos 0)i + (0^4 - 6 \sin 0)j + (2e^{3\times 0})k)[/tex]

           [tex]= (3 \times 1)i + (0 - 0)j + (2e^{0})k)\\\\ = 3i + 0j + (2 \times 1)k)\\\\ = 3i + 0j + 2k \\[/tex]

The value of the coordinates are [tex]3, 0, 2[/tex] . so, the equation of the line is:

[tex]\to \frac{(x-3)}{3 \cos \ t} = \frac{(y-0)}{(t^{4}-6 \sin \ t)} = \frac{(z-2)}{2e^{3t}}=k[/tex]

Answer:

A. 6.466

B. 6

C. 5

D. 30 nominations

Step-by-step explanation:

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

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.

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: 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.
