Answer: I don't understand either :{

But I do know that you have to look at the little letters to answer the questions about the triangle. Like when it asks, "What are the possible values for x?" you have to find x then say what the possible values for x are. Hope that helps a little bit

Answer:

The probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026

Step-by-step explanation:

Mean = \mu = 45

Population standard deviation =\sigma = 6

Sample size = n =25

Sample mean = \bar{x} = 52

We are supposed to find  the probability of observing a sample mean of x = 52 or greater from a sample size of 25 i.e.P(x\geq 52)

Z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}\\Z=\frac{52-45}{\frac{6}{\sqrt{25}}}

Z=5.83

P(Z<52)=0.9999974

P(Z\geq 52)=1-P(z

Hence  the probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026

Find the zeros of x^2+4x=-10 using the quadratic formula
ipn [44]
X^2+4+10=0
x=(-4(+/-)root16-40)/2, so we now know that the zeros are imaginary, because you can't square root a negative number and 16-40 is -24
so the two roots are…
-2+iroot6 and -2-iroot6
