Answer:

Its neither the only value im getting is 864

Answer:

b

Step-by-step explanation:

Answer:

C. 10 times greater

Step-by-step explanation:

every time you move left a number space, the value increases by a multiple of 10x (the opposite is true for moving right)

for example:

1.0

10.0

100.0

10 is 10x greater than 1

100 is 10x greater than 10 or 100x greater than 1

*notice how the number 1 is moving one space to the left

Answer:

the answer is

CO2 (1 atom of carbon and 2 atoms of oxygen)7.31x10-^23

3.34x10-^24 H2(2 atoms of hydrogen)

2821x 10-^23 NH3 (1 atom of nitrogen and 3 atoms of hydrogen

7.64x 10-^ 23 NO2 1 atom of nitrogen and 2 atoms of oxygen

Step-by-step explanation:

i got all of them right so these are all correct!!

Answer:

  ASA

Step-by-step explanation:

The shared angle, the marked angle, and the marked sides between those angles are congruent. That is, you have congruent Angle, Side, Angle, so the ASA postulate applies.

Answer:

first you have to divide the 144 by 4 to get the answer which is 36

Step-by-step explanation:

144÷4=36

then you take 3 × 36= 108 juice boxes

then you take the number of juice boxes which is 36 and divide it by 36 which is 1 case

the you take 6×36=216

288÷36 = 8 cases

Answer:

1. Mean = 55.8

Median = 23

Mode = None

2. Mean = 2.1

Median = 1.4

Mode 0.5

3. Mean = 4.5

Median = 4.5

Mode = 1,4, 5, 8

4. Mean 68

Median 58

Mode = 0

Step-by-step explanation:

Mean = 17 + 25 + 23 + 200 + 14 / 5 = 279/5 = 55.8

Median= Because its odd you put them in order 17, 14, 23, 25, 200 = 23 because it is the middle number. Mode = None

2. Mean = 0.5 + 1.4 + 3.0 + 7.0 + 0.5 +1.8 + 0.5 = 14.7 = 14.7/7 = 2.1

Median = because it is odd you put them in order 0.5, 0.5, 0.5, 1.4, 1.8, 3.0, 7.0 = 1.4 The mode is 0.5 because it repeats three times

3. Mean = 1 + 8 + 5 + 4 + 1 + 8 + 5 + 4 = 36/8 =4.5

Median = Because its even you divide by the two middle numbers = 1, 1, 4,4, 5, 5 , 8 , 8 = 4+5 = 9/2 = 4.5 Mode = 1, 4, 5, and 8 are the numbers that are repeated most often.

Mean = 0+78+99+58+65+0+47+38+227 = 68 Median, Because there is an odd number you get the odd number from the middle. 0, 0, 38, 47, 58, 65, 78, 99, 227 = 58 Mode = 0 because it repeats more often.

Sorry I kept commenting I'm new to this platform!

ok I can help

we have to fill it in first - so the question is :

-4 + 6(-3)

so now we just solve it

-4 + -18

because 6 times - 3 is -18

then I'm pretty sure u just add -4 and -18 together witch is..

-22

srry I forgot it said -3 but yes this is the answer

Answer:

The length of Louis's basement is 85 feet.

Step-by-step explanation:

The area of the basement, A = 4,335 square feet

The width of the basement is  3/5 its length.

Let length be l.

Width = (3/5)l

The area of the basement is given by :

[tex]A=l\times b\\\\4,335 =l\times \dfrac{3}{5}l\\\\4,335 =\dfrac{3}{5}l^2\\\\l^2=\dfrac{4,335 \times 5}{3}\\\\l=\sqrt{\dfrac{4335\times5}{3}}\\\\l=85\ ft[/tex]

So, the length of Louis's basement is 85 feet.

Answer:

-107

Step-by-step explanation:

x4-5^3+ 3^2-2x + 7

2x−109/x−1

1   2   −109

    2

second step

1   2                    -109

                    1 * 2 = 2

    2 (-109) + 2 = -107

Coefficients are 2, and -107

Therefore the quotient is 2 and the remainder is -107

Answer:

x = 90 degrees

y = 28 degrees

Step-by-step explanation:

x: all the angles in the middle are 90

y: 180 - 90 - 62 = 28

Answer: 8x62 i found this so here is why this is correct hope it helps!

( I am a middle schooler btw)

Step-by-step explanation: 8 x 60 = 480 + 2 =482 so 8 x 62 is correct

Total             8420.7         8509667.624

Mean [tex]$\bar X = \sum \frac{X_i}{n}$[/tex]

              [tex]$=\frac{8420.7}{15}$[/tex]

              = 561.38

Median :

[tex]$Q_2 = \left(\frac{1}{2}n+\frac{1}{2}\right)^{th}$[/tex]value

     [tex]$ = \left(\frac{1}{2}\times 15+\frac{1}{2}\right)^{th}$[/tex]value

    = 202.7

Percentile = [tex]$\left(\frac{P}{100} \times n + \frac{1}{2}\right)^{th}$[/tex]  value

                 = [tex]$\left(\frac{50}{100} \times 15 + \frac{1}{2}\right)^{th}$[/tex] value

                 = 202.7

Percentile = [tex]$\left(\frac{P}{100} \times n + \frac{1}{2}\right)^{th}$[/tex]  value

                 = [tex]$\left(\frac{40}{100} \times 15 + \frac{1}{2}\right)^{th}$[/tex] value

[tex]$Q_1 = \left(\frac{1}{4}n+\frac{1}{4}\right)^{th}$[/tex]value

     [tex]$ = \left(\frac{1}{4}\times 15+\frac{1}{4}\right)^{th}$[/tex]value

    = 172

[tex]$Q_3 = \left(\frac{3}{4}n+\frac{3}{4}\right)^{th}$[/tex]value

     [tex]$ = \left(\frac{3}{4}\times 15+\frac{3}{4}\right)^{th}$[/tex]value

    = 574.1

Therefore, the range = highest value - lowest value

                                  = 3194.3 - 121.5

                                  = 3072.8

Now the interquartile range = [tex]$Q_3-Q_1$[/tex]

                                              = 574.1 - 172

                                             = 402.1

Answer:

the appropriate operation count is 27 times longer than the original one.

Step-by-step explanation:

Given the data in the question;

let us consider the approximate operation count for the system of n₁ equation in n₁ unknowns as; [tex]\frac{2}{3}n[/tex]₁³ Or  

O₁ =  [tex]\frac{2}{3}n[/tex]₁³

so if the value of the unknowns is tripled i.e, n₂ = 3n₁,

the appropriate operation count will be;

O₂  =  [tex]\frac{2}{3}n[/tex]₂³

= [tex]\frac{2}{3}(3n_{1})[/tex]³

= [tex]\frac{2}{3}[/tex] × 27 × n₁³

= 27(  [tex]\frac{2}{3}n[/tex]₁³  )

O₂ = 27(O₁)

Therefore, the appropriate operation count is 27 times longer than the original one.
