Answer:    38 students

Step-by-step explanation:

Is a measure of 25 inches​ "far away" from a mean of 16 ​inches? As someone with knowledge of​ statistics, you answer​ "it depen
erik [133]

Answer:

a) 25 is 3 standard deviation from the mean

b) Is far away from the mean, only 0,3 % away from the right tail

c) 25 is pretty close to the mean (just a little farther from 1 standard deviation)

Step-by-step explanation:

We have a Normal Distribution with mean 16 in.

Case a) we also have a standard deviation of 3 inches

3* 3 = 9  

16 (the mean) plus 3*σ  equal 25 in. the evaluated value, then the value is 3 standard deviation from the mean

Case b) 25 is in the range of 99,7 % of all value, we can say that value is far away from the mean, considering that is only 0,3 % away from the right tail

Case c) If the standard deviation is 7 then

mean + 1*σ  =  16 + 7 =23

25> 23

25 is pretty close to the mean only something more than 1 standard deviation

What value of k makes the equation true? (5a^2 b^3)(6a^k b)=30a^6 b^4
Ratling [72]

we are given

(5a^2 b^3)(6a^k b)=30a^6 b^4

Firstly, we will simplify left side

and then we can solve for k

Left side is

(5a^2 b^3)(6a^k b)

we can arrange like terms

(5a^2 6a^k)(b^3 b)

(5\times 6 a^2a^k)(b^3 b)

(30 a^2a^k)(b^3 b^1)

now, we can use property of exponent

a^m \times a^n=a^{m+n}

(30 a^{2+k})(b^{3+1})

30a^{2+k}b^{4}

now, we can equate it with right side

and we get

30a^{2+k}b^{4}=30a^6 b^4

We can see that both sides have 30 , a and b

and they are equal

so, exponent of a must also be equal

2+k=6

now, we can solve for k

2+k-2=6-2
