Z to the power of 2 =1
stiv31 [10]

That would be written as:

z^{2} = 1


And the step-by-step equation would be:

z^{2} = 1 → we take the 2 to the right side of the equation and do the IO*

z = \sqrt{1} →we solve for \sqrt{1}

z = 1 → final answer


*Ps - IO is not an existing term and stands for inverse operation. In this case, because when we take to 2 to the right side of the equation (the 2 is a power) it'll have to turn into a square root (because exponents and roots are inverse operations)



Hope it helped,

12x−39≤9 AND−4x+3&lt;−6, just solving for x<br><br> please answer ASAP
kari74 [83]

<u>Answer:</u>

Solving for x in 12x − 39 ≤ 9 and −4x + 3 < −6 we get 2.25 < x ≤ 4

<u>Solution</u>:

Need to find the value of x which satisfies following two given expressions

12x − 39 ≤ 9      ------(1)

−4x + 3 < −6     ------ (2)

Lets first solve expression (1)

12x − 39 ≤ 9  

Adding 39 on both sides , we get

12x−39 + 39  ≤ 9  +39

=>12x ≤ 48

=> x  ≤ 48/12

=> x ≤ 4    

Now solving expression (2)

−4x+3<−6      

=> -4x < -6 – 3

=> -4x < -9  

=> 4x > 9

=> x > 9/4

=> x > 2.25

So from solution of expression (1) and (2) , we get x ≤ 4   and x > 2.25

Hence required value of x is 2.25 < x ≤ 4.

Which normal distribution has the greatest standard deviation? A normal distribution is shown. The curve peaks at 96 and hits th
s2008m [1.1K]

Answer:

A) Case A we dont rally have a nrmal distribution in case C

(See step by step explanation)

Step-by-step explanation:

Normal Distribution curve is a function of mean and standard deviation with these values we can plot the curve. The mean usually denoted by  μ will show the most frecuent value of the population ( or sample ) and the standard deviation is a measure of the spread of the values around the mean. If we assume that for hitting the axis we should understand that the two given values  are the end of the curve, then we can evaluate how spread is each of the curve then:

case A    115  -  75   =  40

case B      72 -  48  =   24

case C      We do not touch  x -axis in this case so  curve is open we can  find distribution values (theoretically) from -∞   to  +∞  we dont really have a normal distribution in this case.

case D  38  - 28  =  10

Then if we dismiss case C the biggest standard deviation will be case A.

Note: we do not need to calculate standard deviation we just need to look how width it is
