Answer:
An improper fraction
Step-by-step explanation:
15/10 is 1 and 1/2, but it's a bigger number over a smaller number.
1) 475
2)375
You need to multiply 25 by 27 and you get 675 then to get answer one you need to multiply 10 by 20 to get 200 the take 200 away from 675 to get 475 then do the same thing with the second problem 20x15 which is 300 the take 300 away from 675.
1) Call x the sample mean = 3.56
2) Call s the sample standard deviation = 0.2
3) Given that the variable is normally distributed and the sample is large, you determine the interval of confidence from:
x +/- Z(0.5) s/√n
Wehre Z(0.5) is the value of the probabilities over 5% (90% of confidence mean to subtract 10%, which is 5% for each side (tails) of the normal distribuition) and is taken from tables.
Z(0.5) = 0.3085
Then the inteval is
x +/- 0.385 *s /√n = 3.56 +/- 0.385 * 0.2/√45
3.56 +/- 0.011 = ( 3.549, 3.571). This is the answer.
In the given problem, the
numerical value of 805, which is in the tens place, we can first elaborate and
clearly specify the order of numbers by using the expanded form:
<span><span>1. </span><span> 800 = eight
hundred / hundreds</span></span>
<span><span>2. </span><span> 0 = zero / tens</span></span>
<span><span>3. </span><span> 5 = five / ones
</span></span>
Conclusively the tens value of
the number is zero or none, since zero is not a real number then it can’t be
considered but nevertheless, the value is 0 expressed with respect to the whole
numbers.
