Answer:

102.35

8.5 is the diameter and we need the radius which is 4.25. 4.25 ^ 3 is 76.75625 and times that by 4 gives us 307.0625 and divide that by 3 gives me 102.35 rounded to the nearest hundrenth

Answer:

6

Step-by-step explanation:

When dividing by a fraction flip it over and multiply

2 / (1/3) = 2 * 3/1

2 / (1/3) = 6/1

2 / (1/3) = 6

Answer:

(-4 - (-2))/(2 - (-2)) = -2/4 = -1/2

Step-by-step explanation:

Pick either point.

y - (-4) = (-1/2)(x - 2)

y + 4 = (-1/2)x + 1

y = (-1/2)x - 3

Answer:

4 schools

Step-by-step explanation:

Based on the box plot you have given above, the answer would be 20% of the total schools participated for 6 years or more. This is because the part of the box plot wherein it hits 6 years and above is 20%. Thus, if there are 20 schools, then the 20% of it would be 4. In conclusion, there are 4 schools that participated for 6 years or more.

Answer:

Cost of each hoodies = $25.5

Cost of each t-shirt = $12.75

Step-by-step explanation:

Given:

Cost of 2 t-shirt and 2 hoodies = $76.50

Cost of 5 t-shirt and 3 hoodies = $140.25

Find:

Cost of each t-shirt

Computation:

Assume;

Cost of each t-shirt = t

Cost of each hoodies = h

So,

2t + 2h = 76.50..........eq1

5t + 3h = 140.25..........eq2

Eq 1 x 2.5

5t + 5h = 191.25.............eq3

Eq3 - Eq2

2h = 51

h = 25.5

Cost of each hoodies = $25.5

2t + 2h = 76.50

2t + 2(25.5) = 76.50

t = 12.75

Cost of each t-shirt = $12.75

The slope of side CD in rhombus CDEF is -2/5. Therefore, option B is the correct answer.

A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square.

Given that, the rhombus is CDEF and the slope of FC is 5/2.

Here, sides FC and CD are perpendicular.

The slope of a line perpendicular to given line is m₁=-1/m₂

Slope of CD is -2/5.

Therefore, option B is the correct answer.

Answer:

6 hours

Step-by-step explanation:

speed = distance/ time

6000meters to km = 6000/1000= 6km

speed for the first race = 6/2

speed = 3km/hr

for the second race

speed = distance/time

3 = 18/time

cross multiply

3* t = 18

divide both sides by 3

t = 18/3

t = 6 hours

Answer:

Ronald will take 6 hours to complete the 18 km race if he maintains this speed.

Step-by-step explanation:

6000m in 2h = 6km in 2h

Volume can be measured by counting the number of unit cubic in a

three-dimensional​ figure.

The amount of space occupied by a three-dimensional figure as measured in cubic units.

Volume is the three- dimensional property, its basic units is always in cube.

Volume generally told us how much capacity can handle which we express it with the help of cubic units.

Volume doesn't wok on two dimensional bodies as well as the square is used for finding the area of the figure.

Thus, Volume can be measured by counting the number of unit cubic in a

three-dimensional​ figure.

Answer:

We have that [tex]f(a) = f(b)[/tex] if [tex]a = \pm b[/tex], which does not respect the condition for the existence of an inverse function, which means that [tex]f^{-1}(x)[/tex] does not exist for this function.

Step-by-step explanation:

Existence of an inverse function:

An inverse function will exist if: f(a) = f(b) only if a = b.

In this question:

[tex]f(a) = -\frac{1}{7}\sqrt{16 - a^2}[/tex]

[tex]f(b) = -\frac{1}{7}\sqrt{16 - b^2}[/tex]

[tex]-\frac{1}{7}\sqrt{16 - a^2} =-\frac{1}{7}\sqrt{16 - b^2}[/tex]

[tex]\sqrt{16 - a^2} = \sqrt{16 - b^2}[/tex]

[tex](\sqrt{16 - a^2})^2 = (\sqrt{16 - b^2})^2[/tex]

[tex]16 - a^2 = 16 - b^2[/tex]

[tex]a^2 = b^2[/tex]

[tex]a = \pm b[/tex]

We have that [tex]f(a) = f(b)[/tex] if [tex]a = \pm b[/tex], which does not respect the condition for the existence of an inverse function, which means that [tex]f^{-1}(x)[/tex] does not exist for this function.

Answer:

6 and 8

Step-by-step explanation:

Pythagorean theorem: a² + b² = c²

Given this,

(3x)² + (4x)² = 10²

9x² + 16x² = 100

25x² = 100

Divide both sides by 25

x² = 4

x = 2

Substitute this into 3x and 4x.

3x = 3 * 2 = 6

4x = 4 * 2 = 8

Thus, the answer is 6 and 8

Margin of error is 4.645% with 95% confidence that the mean number of hours all the residents of the city are watching news on television is 1.8 .

Data given :

A researcher surveyed 220 residents of a city about the number of hours they spend watching news on television each day. The mean of the sample was 1.8 with a standard deviation of 0.35 .

The researcher can be 95% confident that the mean number of hours all the residents of the city are watching news on television is 1.8 with what margin of error,

By formula of margin of error = [tex]M = 1.96 \times S / \sqrt{N} ,[/tex]

[tex]Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}}[/tex]

z - represents the z-value for the required confidence level .

s - represents the standard deviation of the sample .

N - represents the sample size .

Now, using the above information, compute the margin of error as -

[tex]\therefore \ Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}} \\= 1.96 \times \frac{0.35}{\sqrt{220}}[/tex]

[tex]=0.04625 (rounded \ to \ 5\ decimal\ places) \\\\ =4.625\%[/tex]

Thus, the margin of error, M, is approximately 4.625% .
