Select one of the factors of x2y3 − 11x2y + 6y2 − 66.
(x2y + 6)
(x2y − 6)
(y2 + 11)
(y − 3)
Answers
Step-by-step explanation:
The factors of the equation x2y3 - 11x2y + 6y2 - 66 can be found by taking out the common terms.
x2y3 - 11x2y + 6y2 - 66
Let us take out the common from the first two terms.
⇒ x2y(y2 - 11)------>(1)
Take out common from the last two terms.
⇒ + 6 (y2 - 11)------>(2)
By combining these two, we get
x2y(y2 - 11) + 6(y2 - 11)
⇒ (x2y + 6)(y2 - 11)

If:

KL=3x + 7, and
JK = 8x + 8,
Find KL.
J

L
Answers
Answer:
KL = 10
Step-by-step explanation:
Given:
[tex]JL=26[/tex]
[tex]KL=3x+7[/tex]
[tex]JK=8x+8[/tex]
From inspection of the given diagram:
[tex]JK+KL=JL[/tex]
Substitute the given values into the found equation and solve for x:
[tex]\implies 8x+8+3x+7=26[/tex]
[tex]\implies 11x+15=26[/tex]
[tex]\implies 11x+15-15=26-15[/tex]
[tex]\implies 11x=11[/tex]
[tex]\implies \dfrac{11x}{11}=\dfrac{11}{11}[/tex]
[tex]\implies x=1[/tex]
Substitute the found value of x into the expression for KL:
[tex]\implies KL=3(1)+7[/tex]
[tex]\implies KL=3+7[/tex]
[tex]\implies KL=10[/tex]
Formula we use,
→ JK + KL = JL
Now the value of x will be,
→ (8x + 8) + (3x + 7) = 26
→ 11x + 15 = 26
→ 11x = 26 - 15
→ x = 11/11
→ [ x = 1 ]
Then the value of KL will be,
→ 3x + 7
→ (3 × 1) + 7
→ 3 + 7 = 10
Hence, the value of KL is 10.

Answers
The coordinates weighted average is 6.
How is the weight average calculated?The whole query is as follows:
The weights of the coordinates 3 and 8 are 2 and 3, respectively. Additionally, we must determine the weighted average.
The parameters are as follows:
Three has a weight of two.
The weight of coordinate 8 is 3.
Next, the weight average is determined as follows:
Weight average is equal to the product of the weight and the coordinates.
We thus have:
Average weight: (3 * 2 + 8 * 3)/(2 + 3)
Assess the quotient.
Average weight = 6

c. probability that the mother in this sample had a premature baby given that the mother admitted to smoking
Answers
Probability that the mother in this sample had a premature baby given that the mother admitted to smoking is 50 percent.
What is probability?Likelihood is the part of science concerning mathematical depictions of how likely an occasion is to happen, or how likely it is that a suggestion is valid. The likelihood of an occasion is a number somewhere in the range of 0 and 1, where, generally talking, 0 demonstrates difficulty of the occasion and 1 shows conviction.
P (A) is the probability of an event “A”
n (A) is the number of favorable outcomes
n (S) is the total number of events in the sample space
The higher the likelihood of an occasion, the more probable it is that the occasion will happen. A straightforward model is the throwing of a fair coin. Since the coin is fair, the two results are both similarly likely; the likelihood of "heads" approaches the likelihood of "tails"; and since no different results are conceivable, the likelihood of by the same token "heads" or "tails" is 1/2.

Compare the digits in the hundredths place of 4.241 and 4.25.
Answers
4 is less than 5, so 4.241 is less than 4.25.
Given the numbers are 4.241 and 4.25.
Because 4.241 and 4.25 have the same units and tenth digit (4.2 = 4.2)
so we need to compare the hundredths place that is, 0.041 with 0.05.
A decimal's distance from one whole increases as it increases in size. A decimal is further away from one whole the smaller it is. The amount of digits in each decimal should be your primary point of focus. Each of them contains two digits, allowing for immediate comparison.
The number following the decimal point is called the hundredths place. Round up the number of hundredths if the third number after the decimal is 5 or above. Keep the hundredths number constant if the number in the third position after the decimal point is 4 or less.
0.041 < 0.05
hence we get 4.241 < 4.25

James is making orange juice from concentrated frozen orange juice that he must mix with water. The concentrated juice is in 12 fluid ounce cartons. The ratio of orange juice concentrate to water is 12 fluid ounces to 36 fluid ounces. If James needs 4.5 gallon of orange juice, which is 576 fluid ounces, how many cartons of concentrated orange juice does he need?
Group of answer choices
Answers
In order to make 4.5 gallons of orange juice, she will need 12 cartons of concentrated orange juice.
The volume of concentrated orange juice is equal to 12 fluid-ounce cartons.Orange juice concentrate to water ratio = 12 fluid ounces to 36 fluid ouncesThe amount of orange juice required by James is 4.5 gallons (576 fluid ounces).So,
The orange juice concentrate to water ratio is 12:36.
Now, let's call 'x' the amount of concentrated orange juice in 4.5 gallons of orange juice and 'y' the amount of water in the 4.5 gallons of orange juice we have;
x + y = 4.5 (gallons) ...(1)x:y = 12:36 = 1:3∴ x/y = 1/33·x = y ...(2)We can conclude the following from equations (1) and (2):
x + y = 4.5x + 3·x = 4.5x = 4.5/4 = 1.125x = 1.125x = 1.125 gallons of concentrated orange juice in 4.5 gallons of orange juice:
y = 3 × x = 3 × 1.125 = 3.375y = 3.375y = 3.375, the amount of water in 4.5 gallons of orange juice.
As a result, we have;
4.5 gallons = 576 fluid ounces1.125 gallons = (576/4.5) × 1.125 = 144 fluid ouncesThe number of fluid ounces in a carton is 12 ounces.
The number of cartons in 144 fluid ounces = 144 fluidounces ÷ 12 fluidounces/carton = 12 cartonsIn 4.5 gallons of orange juice, x = 1.125 gallons = 144 fluidounces = 12 cartons of concentrated orange juice
x = 12 cartons of orange juice = the amount of concentrated orange juice she requires in 4.5 gallons of orange juiceThe amount of concentrated orange juice she requires in 4.5 gallons of orange juice, x = 12 cartons of orange juiceTherefore, in order to make 4.5 gallons of orange juice, she will need 12 cartons of concentrated orange juice.

the sides of a triangle are of lengths 13, 14, and 15. the altitudes of the triangle meet at point h
Answers
The ratio HD:HA is 5/11 when the sides of a triangle are of lengths 13, 14, and 15.
What do you mean by heron's formula?When the lengths of all three sides are known, the geometry formula Heron's formula, which bears Hero of Alexandria's name, determines the area of a triangle. There is no need to first determine the angles or other distances in the triangle, unlike other triangle area formulas. Heron of Alexandria is credited with developing the Heron's formula, which determines the area of a triangle in terms of the lengths of its sides. If the side lengths are represented by the symbols a, b, and c: Area is equal to the square root of (a + b + c)/2, where s is half the perimeter.
By Heron's Formula, the area of this triangle is 84 Thus the height perpendicular to AB has a length of 11.2, and by the Pythagorean Theorem, AE and EB have lengths 6.6 and 8.4, respectively. These lengths tell us that C is at.
The slope of BC is (0-11.2)/(15-6.6)=-4/3, and the slope of AD is 3/4 by taking the negative reciprocal of -4/3. Therefore, the equation of line AD can best be represented by y=(3/4) x.
We next find the intersection of CE and AD . We automatically know the x -value; it is just 6.6 because CE is a straight line hitting (6.6,0). Therefore, the y -value is at (3/4)* 6.6=4.95. Therefore, the intersection between CE and AD is at (6.6,4.95) .
We also need to find the intersection between BC and AD . To do that, we know that the line of AD is represented as y=3/4x, and the slope of line BC is -4/3. We just need to find line BC 's y-intercept. So far, we have y=-4/3x+b, where b is a real y-intercept. We know that B is located at (15,0), so we plug that into the equation and yield b=20. Therefore, the intersection between the two lines is
(3/4)x=-(4/3)x+20
⇒9x=-16x+240
⇒25x=240
⇒x=9.6
Now y=(3/4)*x=(3/4)*9.6=7.2
⇒y=7.2
After that, we use the distance formula: HA has a length of
√(6.6-0)²+(4.95-0)²=√(1089/25)+(9801/400)
=√(1089*16+9801)/400
=√27225/400=√1089/16=33/4=8.25
and HD has a length of
√(9.6-6.6)²+(7.2-4.95)²=√(3)²+(36/5-99/20)²
=√(9)+(81/16)
=√225/16=15/4=3.75
So the ratio os HD:HA is
⇒3.75/8.25=15/33=5/11
