Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The standard deviation is 
The margin of error is 
From the question we are told the confidence level is 95% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally the sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%20%2A%20%20%5Csigma%20%7D%7BE%7D%20%5D%20%5E2)
=> ![n = [1.96 * 3750 }{200} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B1.96%20%20%2A%20%203750%20%7D%7B200%7D%20%5D%20%5E2)
=>
Answer:
x= -6
Step-by-step explanation:
equation: -10 - 2x = 2x + 14
subtract 14 from both sides: -24 - 2x = 2x
add 2x to both sides: -24 = 4x
divide both sides by 4: -6 = x
Answer:
positive 3
Step-by-step explanation:
-8 + 11 is 3. the other way you can think of it is by subtracting 8 from 11.
Answer:I’m only doing 3 and id k if I’m right either so lol but A is a reflection I think and I don’t think B is congruent which mean some of the size and not like right like they don’t match or something like that and to be nice on number 5 trace the tree up the blue zigzag yea trace it rly hard fold it then rub on the back of the paper the shape should end up on the other side that’s how I cheated try doing that with number 4 too
Step-by-step explanation:I’m sry if that doesn’t make sense I tryed
