two boats leave a dock at the same time. one boat travels south at and the other travels east at . after half an hour, how fast is the distance between the boats increasing?
After half an hour the two boats will be at a distance of 68 mph
Given,
Both boats are moving in a direction that creates a right angle triangle. The lengths of the triangle's legs are the distances that both boats travelled going straight south and straight east. The hypotenuse of a right angle triangle is the distance between them after t hours.
Let x stand for the length of the triangle's shorter south leg.
Let y stand for the length of the right angle triangle's longer (east) leg.
Assume that z is the hypotenuse.
Using the Pythagorean theorem
Hypotenuse² = opposite side² + adjacent side²
Therefore
z² = x² + y²
We would discriminate with regard to t in order to ascertain the speed of the distances' alterations.
It develops,
2zdz/dt = 2xdx/dt + 2ydy/dt- - - -- - -1
One travels south at 32 mi/h and the other travels east at 60 mi/h. It means that
dx/dt = 32
dy/dt = 60
Distance = speed × time
Since t = 0.5 hour, then
x = 32 × 0.5 = 16 miles
y = 60 × 0.5 = 30 miles
z² = 16² + 30² = 256 + 900
z = √1156z = 34 miles
Substituting these values into equation 1, it becomes
2 × 34 × dz/dt = (2 × 16 × 32) + 2 × 30 × 60
68dz/dt = 1024 + 3600
68dz/dt = 4624
dz/dt = 4624/68
dz/dt = 68 mph

explain how the is related to the standard error of the estimated difference in average birth weight for smoking and nonsmoking mothers.
Nearly half of the newborns among nonsmokers (56 out of 115, 48.7%) have birth weights between 3,000 and 4,000 grammes. 40 of 74, or 54%, of the infants born to smokers have birth weights between 2,000 and 3,000 grammes, with fewer infants in the larger weight groups.
What is birth weight?
The body weight of a newborn is referred to as birth weight. Infants of European descent typically weigh between 2.5 and 4.5 kilogrammes at birth, with an average of 3.5 kilograms. South Asian and Chinese babies weigh about 3.26 kilogrammes on average.
Babies born to nonsmokers typically weighed between 1,000 and 5,000 grammes. Babies born to smokers often ranged in weight from 500 to 4500 grammes.
However, we also notice some significant variations between the two groups' normal ranges of birth weights. With fewer infants in the lower weight ranges, nearly half of the newborns among nonsmokers (56 out of 115, 48.7%) have birth weights between 3,000 and 4,000 grammes. 40 of 74, or 54%, of the infants born to smokers have birth weights between 2,000 and 3,000 grammes, with fewer infants in the larger weight groups.

In probability, what do combination and permutation mean?
Combinations and permutations may appear to be synonyms. However, they are defined differently in probability theory. Combinations: The sequence of results is irrelevant. Permutations: The sequence of events matters.
If an event is made up of numerous other events (i.e., when it is a list), we may calculate the probability that it will occur with the help of permutations and combinations. If the sequence of the events doesn't matter, we have a combination; if it does, we have a permutation. A permutation can be defined as an ordered combination.
An ordered combination is what is meant by a permutation.
The number of permutations of n objects, taken r at a time, is calculated using the formula below:
P(n,r)=n!(n-r)!
The following formula calculates the number of combinations of n objects taken r at a time: C(n,r)=n!/(n-r)!r!
there are 26^3 combinations of letters. And 10^3 combinations of numbers.
So the total combinations is 26^3 x 10^3 = 17,576,000

To do a conversion (or equivalent) you must multiply the value to be converted by the conversion factor of the start unit and then divide the result by the conversion factor of the destination unit.
For example, we want to know how many centimeters equals 12 yards?
# convert the units in meters (which is the SI base unit for the lengths)
# 1 yard = 0.9144 meters
# 1 centimeters = 0.01 meters
# derive the conversion factor between the yard and centimeters by dividing the factors found
# 0.9144/0.01 = 91.44
# 1 yd = 91.44 cm
# now we multiply the amount to be converted by the conversion factor found
# 12 * 91.44 = 1097.28
# result: 12 yd equals 1097.28 cm

Two polygons are similar, and the ratio s1/s2 of their corresponding sides is 8/7 then the ratio of their areas, a1/a2 = 64/49.
In the given question, two polygons are similar, and the ratio s1/s2 of their corresponding sides is 8/7.
We have to find the ratio of their areas, a1/a2.
As we know that, the measurement of the area that a polygon encloses serves as its definition. The area of a polygon is the space that it takes up in a two-dimensional plane since polygons are closed plane structures.
As given that, two polygons are similar.
The ratio of their corresponding sides are
s1/s2 = 8/7
According to properties of similar polygon, the ratio of the areas of the two polygons is the square of the ratio of the sides. Hence,
a1/a2 = (s1/s2)^2
a1/a2 = (8/7)^2
a1/a2 = 64/49
Hence, two polygons are similar, and the ratio s1/s2 of their corresponding sides is 8/7 then the ratio of their areas, a1/a2 = 64/49.

Given:
an executive hires 3 office workers from 8 applicants.
a ) .
Number of ways = C ( 8 , 3 )
C ( n , r ) = n! / ( n - r ) ! r!
C ( 8 , 3 ) = 8! / ( 8 - 3 ) ! 3!
= 8! / 5! * 3 !
= 8 * 7 * 6 * 5! / 5! * 3!
= 56 * 6 / 3!
= 56 * 6 / 3 * 2 * 1
= 56 * 3 / 2 * 1
= 28 * 3 / 1
= 28 * 3
= 84 ways

find the probability if two dice are rolled. (enter the value of probability in decimals. round the answer to three decimal places.)
The probability of getting a total of 8 when two dice are rolled is 0.139.
Probability is a number that expresses the likelihood or chance that a specific event will take place. Probabilities can be represented by proportions on a 0–1 scale.
A single die will have six sides with the numbers: 1, 2, 3, 4, 5, and 6. Each of these events is equally likely to occur if the dice are rolled fairly. So the probability of getting any side of the number is 1/6. Therefore, the probability of getting 1 in dice is 1/6, 2 is 1/6, and so on.
Therefore, the total possible outcomes are the multiplication of the total possible outcomes on dice 1 and dice 2, which is 36.
This possible outcome of rolling two dice is given by,
[tex]\left\{\begin{array}{ccccccc}(1, 1)&(1, 2)& (1, 3)&(1, 4)&(1, 5)&(1, 6)\\(2, 1)&(2, 2)&(2, 3)&(2, 4)&(2, 5)&(2, 6)\\(3, 1)&(3, 2)&(3, 3)&(3, 4)&(3, 5)&(3, 6)\\(4, 1)&(4, 2)&(4, 3)&(4, 4)&(4, 5)&(4, 6)\\(5, 1)&(5, 2)&(5, 3)&(5, 4)&(5, 5)&(5, 6)\\(6, 1)&(6, 2)&(6, 3)&(6, 4)&(6, 5)&(6, 6)\end{array}\right\}[/tex]
The probability of getting a total of 8 from both dice is given by, (2, 6) (3, 5) (4, 4) (5, 3) (6, 2). So the number of favorable outcomes is 5 and the total outcome is 36. The probability is P(getting a total of 8 from both dices)=5/36= 0.139.
The answer is 0.139.
