72 numbers can be formed this way.

Using just odd numbers, we could have numbers in the 3000s, 5000s, or 7000s that fit this criteria.

For each one of these, after the thousands digit is chosen, there are only 4 odd numbers that can be used for the hundreds digit, since no digits can repeat. Then there are 3 numbers possible for the tens digit and 2 numbers possible for the ones digit. This gives us 4(3)(2) = 24 possibilities for the 3000s, 5000s, and 7000s; 3(24) = 72.

Answer:

$(\frac{1}{2}, - \frac{1}{2} )$

Step-by-step explanation:

The properties of circumcenter give that it lies at the midpoint of the hypotenuse if it is of a right triangle.

Now, the given triangle is a right triangle and the two ends of the hypotenuse WU are U(-3,2) and W(4,-3).

Therefore, the mid point of the hypotenuse WU will be given by $(\frac{-3 + 4}{2}, \frac{2 - 3}{2}) = (\frac{1}{2}, - \frac{1}{2} )$ .

Therefore, the circumcenter of the right triangle Δ UVW will be $(\frac{1}{2}, - \frac{1}{2} )$ . (Answer)

The confidence interval formula is computed by:

Xbar ± Z s/ sqrt (n)

Where:

Xbar is the mean

Z is the z value

S is the standard deviation

N is the number of samples

So our given are:

90% confidence interval with a z value of 1.645

Sample size 40, 45

Mean 180, 179

Standard deviation 2, 4

So plugging that information in the data will give us a confidence interval:

For 1:

Xbar ± Z s/ sqrt (n)

= 180 ± 1.645 (2 / sqrt (40))

= 180 ± 1.645 (0.316227766)

= 180 ± 0.520194675

= 179.48, 180.52

For 2:

Xbar ± Z s/ sqrt (n)

= 179 ± 1.645 (4 / sqrt (45))

therefore, the answer is letter b
