Now when we talk about place values we have ones tens hundreds thousands ten thousands and so on. So when you look at no.1 its place value is ones because 1 is the first value.

So 2 is in tens.

Now the difference of tens and hundreds is tens follows the 2 place value and hundreds the next.

Answer:

4544

Step-by-step explanation:

The underlined sentence means that the 2nd and third values must be different, for example

4554 has 5 in the 2nd and 3rd place so cannot be this

4545 and 4544 have 4 and 5 in 2nd/3rd place so this is fine

Since the number is even then it is 4544

Suppose 11 people arrive at a bank at the same time. In how many ways can they line up to wait for the next available teller?

tresset_1 [31]

The answer would be C) because there are 11 possibilities of who can line up first, and after the first person, 10 possibilities, then 9, and so on. So you would need to multiply 11x10x9x8x...x1.

A researcher wants to estimate the mean commute time of residents in Westchester County. The researcher samples 40 commuters and

Ksenya-84 [330]

Answer:

21.759

Step-by-step explanation:

Given that :

Mean (m) = 25

Standard deviation (s) = 12.5

Sample size (n) = 40

α = 90%

The confidence interval is obtained using the relation:

Mean ± Zcritical * s/sqrt(n)

Zcritical at 90% confidence interval = 1.64

25 ± 1.64 * (12.5/sqrt(40))

Lower boundary : 25 - 1.64(1.9764235) = 21.75866546

Upper boundary : 25 + 1.64(1.9764235) = 28.24133454

(21.759, 28.241)

Hence, lower bound of confidence interval is : 21.759

Taya2010 [7]

Answer:

The equation of the sraight line 3x- y+ 6 =0

Step-by-step explanation:

Explanation:-

Given that the gradient of the function

|gradf| = 3 and point (-1,3)

Given that the slope of the line

m = 3

The equation of the straight line passing through the point(-1,3) and slope m =3

$y -y_{1} = m(x-x_{1} )$

y-3 = 3(x-(-1))

y-3 = 3x+3

3x +3-y+3=0

3x- y+ 6 =0

Final answer:-

The equation of the sraight line 3x- y+ 6 =0
