I think the other person miswrote the answer on accident, the right answer is -0.86 and NOT 0.86.

The answer
the table is 

x   0   1  4  5   7
y   3   1  0 -2  -2

<span>the approximate line of best fit to be y = –0.7x + 2.36
so when the value of x=5, the residual value is 

</span><span>y = –0.7(5) + 2.36  =  -1.14 this is the actual value
the predicted value is -2 (for x=5)

and residual value formula is  RS =  y actual value - y predicted value

so RS = -1.14 - (-2) = 0.86

You have five pieces of wood. The lengths of these are shown below.
Deffense [45]

Answer:

1,249 cm or 12.49

Whichever one it asks for

Step-by-step explanation:

First, we need to convert all of the m to cm.

4.04 m = 404 cm

1.6 m = 160 cm

2.87 m = 287 cm

Next, add them all up.

325 + 404 + 73 + 160 + 287 =

1,249 cm

If it asks to convert to m again, then the answer would be 12.49 m

Hope this helps!!!

​You'd like to estimate the proportion of the 12,152 full-time undergraduate students at a university who are foreign students.
Minchanka [31]

Answer:

a) The data distribution consists of ( 7 )​1's (denoting a foreign ​student) and ( 43 )0's (denoting a student from the​ U.S.).

b) The population distribution consists of the​ x-values of the population of 12,152 full-time undergraduate students at the​university, ( 6 )​% of which are​ 1's (denoting a foreign​ student) and ( 94 )% of which are​ 0's (denoting a student from the​ U.S.).

c) The mean is ( 0.06 )

The standard deviation is ( 0.0336 )

The sampling distribution represents the probability distribution of the ( sample ) proportion of foreign students in a random sample of ( 50 ) students. In this​ case, the sampling distribution is approximately normal with a mean of ( 0.06 ) and a standard deviation of ( 0.0336 )
