The slope of a line perpendicular to the given equation of line is 6.
Explain the term slope of the line?A line's slope is how steeply it slopes from LEFT toward RIGHT. The slope of a line is determined by dividing its rise, or vertical change, by its run, or horizontal change. No matter which two locations here on line you choose, the slope of this line will always be constant (it never varies).For the stated question, the equation of the line is given as;
3x + 18y = 10
This can be written as;
y = -3/18 x + 10/18
y = -1/6 x + 5/9
Comparing with general equation of line in slope intercept form.
y = mx + c
slope m = -1/6
The relation of slope for the two perpendicular lines are-
m x m1 = -1
m1 = -1/(-1/6)
m1 = 6
Thus, the slope of a line perpendicular to the given equation of line is 6.

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.

We may determine that the triangles are congruent based on the (B) HL criterion right away.
What are HL criteria?According to the HL Postulate, a right triangle's hypotenuse and leg are congruent if they are also congruent with the hypotenuse and leg of another right triangle.
So, we can see from the accompanying figure that these two triangles share a center line that is parallel to the base.
The two triangles are therefore right-angled triangles.
The hypotenuse of two triangles being congruent is then mentioned as a further argument.

Given that;
Gavin is working for making $14 per hour tutoring and $13 per hour landscaping.
And, Last week Gavin worked a total 10 hours and earned $137.
Now,
Let number of hour for tutoring = x
And, Number of hour for landscaping = y
Since, Gavin is working for making $14 per hour tutoring and $13 per hour landscaping and earned $137.
So, We can formulate;
⇒ 14x + 13y = 137 ..(i)
And, Last week Gavin worked a total 10 hours.
So, We get;
⇒ x + y = 10 ..(ii)
Multiply by 13 in equation (ii) and subtract from (i0, we get;
⇒ 14x + 13y - 13x - 13y = 137 - 130
⇒ x = 7
And, x + y = 10
⇒ 7 + y = 10
⇒ y = 10 - 7
⇒ y = 3

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.

All units of a physical measure are linked via a conversion factor. On this web page for every unit you can find the conversion factor compared to the base unit (SI unit).
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

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.

The number of elements that are common to S and T are 668 elements ,
the correct option is (d) .
In the question ,
it is given that ,
the set S is the set of 2005 positive multiple of 4
that is S = {4,8,12,16,....}
and the set T is the set of 2005 positive multiple of 6
that is T = {6,12,18,24,....}
and since the least common multiple , LCM of 4 and 6 is = 12,
So , elements that are common to set S and T must be multiples of 12.
Since, 4 × 2005 = 8020 and 6 × 2005 = 12030,
the several multiples of 12 that are in set T won't be in set S,
but all multiples of 12 that are in set S will be in set T.
So we have to find the number of multiples of 12 that are in set S.
and since 4 × 3 = 12, that means every 3rd element of set S will be a multiple of 12.
which is = 2005/3 = 668 .
Therefore , there are 668 elements that are common .
