A random variable is not normally distributed, but it is mound shaped. It has a mean of 14 and a standard deviation of 3. If you

take a sample of size 10, can you say what the shape of the sampling distribution for the sample mean is

Answer:

Step-by-step explanation:

from the question,

the mean 14

the standard deviation is 3

and sample size is 10.

since the n which is the sample size is 10, then the distribution is mound shaped.

why?

this is due to the fact that the random variable from which we took the sample is mound shaped.

The sampling distribution of the mean is normally distributed although the question says the random variable is not normally distributed. so the shape is bell shaped and normally distributed.

the standard deviation of the mean is

3/√10

= 0.948

Find the distance between the two points in simplest radical form.
SCORPION-xisa [38]

Answer:

The answer is \sqrt{61}

.

Step-by-step explanation:

The distance formula:

d =  \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}  }

.

☆All we need to do is plug in!

d =  \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}  }  \\ \\  d =   \sqrt{( - 1 - 4) ^{2} + ( - 9 - ( - 3))^{2}  }  \\ d =  \sqrt{( - 5)^{2} + ( - 6) ^{2}}  \\ d  =  \sqrt{25 + 36 }  \\  d =  \sqrt{61}

Find value of unknown angle(s) and state reason/theorem why
Anna71 [15]
Y=90° by inspection
w=180-(50+y)=160-(50+90)=40° 
x=180-(w+x)=180-(40+97)=43° 
z=180-(x+90)=180-(43+90)=47°
