Answer:

x =   \frac{3}{ \sqrt{2} }

Step-by-step explanation:

{x}^{2}  +  {x}^{2}  =  {3}^{2}  \\ 2 {x}^{2}  = 9 \\  {x}^{2}  =  \frac{9}{2}  \\ x =  \frac{3}{ \sqrt{2} }  \\ x = 2.121

Melissa launches a rocket from a 3-meter-tall platform. The height, h, of the rocket, in meters, can be modeled by the given gra
Pachacha [2.7K]
We can model the function between a and b as a linear function of negative slope because it is a short interval and the change is not very significant.
 We have then that the average rate of change in that interval is:
 m = (f (a) - f (b)) / (a-b)
 Substituting the values:
 m = (34.25 - 26) / (2.5-3.6)
 m = -7.5
 Negative, because the function decreases in that interval.
 Answer:
 a reasonable estimate of the average rate of change of the height of the rocket, in meters per second, between a and b seconds is:
 m = -7.5 m / s

Answer:

3. Correlation coefficients can be represented by the variable r

Step-by-step explanation:

Correlation coefficients show if there is a strong or weak  positive or negative relationship, or if there is no relationship between the variables.

Correlation coefficients are negative when the relationship is inversely proportional and positive when the relationship is proportional.

Correlation coefficients can be any value less than or equal to 1 or greater than  or equal to -1.​

3. Consider the following information.P(Z) = 0.73P(A) = 0.25P(Z and A) = 0.15Part A: Determine P(Z|A).Part B: Determine P(AZ).I
krok68 [10]

Ok, so:

For Part A, we have: P(Z|A)=P(Z and A)/P(A)

And if we replace, we got:

P(Z|A) = (0.15)/(0.25) and this is equal to 0.6.

For Part B, we have: P(A|Z)=P(Z and A)/P(Z)

P(A|Z) = (0.15)/(0.73) and this is equal to 0.205.

Can someone answer this?
ad-work [718]

Answer:

Step-by-step explanation:

6x-1+3x+5x+3+4x+8+5x+5=360 degree(sum of exterior angle of a pentagon is 360 degree)

23x+15=360

23x=360-15

x=345/23

x=15

therefore the value of x is 15 degree.
