QveST [7]

Answer: z= -1.636

Step-by-step explanation:

When population standard deviation is known, then the test statistic is given by :-

z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

, where \overline{x} = sample mean, \mu = population mean, n=sample size , \sigma = standard deviation

As per given,

z=\dfrac{55.82-56}{\dfrac{0.77}{\sqrt{49}}}\\\\ z=\dfrac{-0.18}{\dfrac{0.77}{7}}\\\\z=\dfrac{-0.18}{0.11}\\\\z=-1.636

Hence, the e test statistic to see whether the candy bars are smaller than they are supposed to be : z= -1.636

36x+9 equals what<br> big blak vjndjgd
Yuki888 [10]

We can conclude that the equation 36x + 9 equals -1/4.

<h3>What exactly is an equation?</h3>
  • An equation, in its most basic form, is a mathematical statement demonstrating that two mathematical expressions are equal.
  • 3x + 5 = 14, for example, is an equation in which the expressions 3x + 5 and 14 are separated by a 'equal' sign.

So,

  • 36x + 9
  • 36x + 9 = 0
  • 36x = -9
  • x = -9/36
  • x = -1/4

Therefore, we can conclude that the equation 36x + 9 equals -1/4.

Factor k^2 +3x-10 .....
Svetach [21]

Answer:

I think you mean: x^2 + 3x - 10, then

x^2 + 3x - 10

= x^2 + 5x - 2x - 10

=x(x + 5)  - 2(x + 5)

=(x - 2)(x + 5)

Hope this helps!
