Answer:

The required number is 7.

Step-by-step explanation:

It is required to find,

A number say 'x', such that, 27 is 6 more than 3 times the number.

That is, we have the relation, 3x+6=27.

On solving, we get,

3x+6=27

i.e. 3x=27-6

i.e. 3x=21

i.e. x = 7

So, the required number which hold the relation that '27 is 6 more than 3 times the number' is 7.

How can we factorise the expression: 2x^6+17x^3+8?​
LekaFEV [45]

Answer:

(a + 2)( {a}^{2}  - 2a +  4 )(2 {x}^{ 3}  + 1)

Step-by-step explanation:

2x^6+17x^3+8 \\  = 2x^6+16x^3 +  {x}^{3} +8 \\  =  2{x}^{3} ( {x}^{3}  + 8) + 1( {x}^{3}  + 8) \\  = ( {x}^{3}  + 8)(2 {x}^{ 3}  + 1) \\  = ( {x}^{3}  +  {2}^{3} )(2 {x}^{ 3}  + 1)  \\  = (a + 2)( {a}^{2}  - 2a +  {2}^{2} )(2 {x}^{ 3}  + 1)   \\  = (a + 2)( {a}^{2}  - 2a +  4 )(2 {x}^{ 3}  + 1)  \\

tresset_1 [31]

so, you just use the x's from the table and plug them into the equation to find the y.

y=(1)+9

y=10

y=(2)+9

y=11

y=(3)+9

y=12

y=(4)+9

y=13

i hope this helps :)

What would be the correlation coefficient (r) of the following scatter plot?
luda_lava [24]

Answer:

-0.89 (i think)

Step-by-step explanation:

Since the graph seems to be going downwards from the right, it has a negative correlation. And since the data seems to be pretty close together, the correlation must be strong. That narrows the answer down to -0.89

If its wrong then i'm not a smart person, and it's -0.15
