Answer:

Range is 44

mean is 29.7

variance is 289.56

standard deviation is 17.016

Step-by-step explanation:

The data given as follows

3, 24, 30, 47, 43, 7, 47,13, 44, 39

Range = maximum - minimum

             = 47 -3 = 44

mean = [tex]\frac{3+24+30+47+43+7+47+13+44+39}{10}[/tex] = 297/10 = 29.7

variance = [tex]\frac{sum xi^2 }{N} - mean^2 }[/tex]

              = 289.56

SD = [tex]\sqrt{variance}[/tex]  = 17.016

The standard deviation of the given data is not a good measure as the range and standard deviation are far apart. The standard deviation gives how the given data is dispersed from the mean or expected value, while the range gives a rough idea of variability of the data.

Answer:

4.

Step-by-step explanation:

(x^2 + 7x - 9) + (3x^2 - 2x) + (x^2 + 7x - 9) + (3x^2 - 2x)

x^2 + 7x - 9 + 3x^2 - 2x + x^2 + 7x - 9 + 3x^2 - 2x

Rearranging order:

3x^2 + 3x^2 + x^2 + x^2 + 7x + 7x - 2x - 2x - 9 - 9

Combine like terms

8x^2 + 10x - 18

by the way i multiplied for the "."

Answer:

53.3 degrees

Step-by-step explanation:

∆DEF and ∆RSQ are similar. We know this, because the ratio of their corresponding sides are equal. That is:

DE corresponds to RS

EF corresponds to SQ

DF corresponds to RQ.

Also <D corresponds to <R, <E corresponds to <S, and <F corresponds to <Q.

The ratio of their corresponding sides = DE/RS = 6/3 = 2

EG/SQ = 8/4 = 2

DF/RQ = 4/2 = 2.

Since the ratio of their corresponding sides are equal, it means ∆DEF and ∆RSQ are similar.

Therefore, their corresponding angles would be equal.

Thus, m<Q = m<F

Let's find angle F

m<F = 180 - (98 + 28.7)

m<F = 53.3°

Since <F corresponds to <Q, therefore,

m<Q = 53.3°

Answer: The bag of candy corn will take 5 seconds to land on the floor and it will hit it with velocity of 49m/s.

Step-by-step explanation: A free falling object has only Gravitational Force acting on it, so acceleration will be due to gravity, which has magnitude

g = 9.8m/s².

As Professor Sosa drops the bag, its initial velocity and time are 0.

The building has a height of 400ft, so adjusting units: y = 121.92 m and [tex]y_{0}[/tex] = 0.

For this problem, going down will be the positive reference.

Then:

[tex]y=y_{0}+v_{0}t+\frac{g}{2}t^{2}[/tex]

[tex]\Delta y=v_{0}t+\frac{g}{2}t^{2}[/tex]

[tex]121.92=\frac{9.8}{2}t^{2}[/tex]

[tex]t=\sqrt{\frac{121.92*2}{9.8} }[/tex]

t ≈ 5

It will take 5s for the candy corn bag to land on the ground.

Acceleration is the change in velocity per change in time, so:

[tex]g=\frac{\Delta v}{\Delta t}[/tex]

As initial velocity and time are 0 and rearraging it:

v = g.t

v = 9.8*5

v = 49

The bag will hit the ground with velocity of magnitude 49 m/s.

Answer:

27°

Step-by-step explanation:

Let the measure of the angels be 3x, 10x, 7x.

[tex]3x + 10x + 7x = 180 \degree \\ \\ 20x = 180 \degree \\ \\ x = \frac{180 \degree}{20} \\ \\ x = 9 \degree \\ smallest \: angle \: = 3x \\ \\ = 3 \times 9 \degree \\ \\ = 27 \degree[/tex]

Answer:

this is grade what????

Step-by-step explanation:

Answer:

100%

Step-by-step explanation:

Utilization rate =

Hours worked / total working hours per day

Since the bottle works nonstop during a 10-hour day, it worked 10 hours

Utilization rate in percentage = (10/10)×100%

= 100%

Answer:

d. J

Step-by-step explanation:

Given that Raul gets 5 (y) book points for every 125 (x) pages he reads during summer challenge, we can say that his unit rate would be: y/x = 5/125 = 1/25.

Raul's unit rate is 1/25 book point to each page he reads.

Graph J also has a unit rate of 1/25 (y/x).

Therefore graph J models a relationship with the same unit rate.

Answer:

Mean = 32.25

median = 31.5

Answer:

Median = 31.5

Mean  = 32.25

Step-by-step explanation:

Number of data = 8

Ascending order:

    30 , 30 , 31 , 31 , 32 ,  33 , 35, 36

Median = Average of 4th and 5th term

             = (31 + 32) / 2

              = 63/2

              = 31.5

Mean = Sum of all the observations /number of observations

         = (31 + 32 + 36 +31 + 30 + 35 + 33 +30) / 8

         = 258/8  

         = 32.25
