Answer:
x = 19/2 or 9.5
Step-by-step explanation:
a) Distribute.
(4)(x) + (4)(−5) = 18
4x + −20 = 18
4x − 20 = 18
b) Add 20 to both sides.
4x − 20 + 20 = 18 + 20
4x = 38
c) Divide both sides by 4.
4x/4 = 38/4
x = 19/2 or 9.5
Answer:
9.5 or 19/2
Step-by-step explanation:
4 ( x - 5 ) = 18
Step 1 : Divide 4 on both sides.
x - 5 = 18/4
x - 5 = 4.5
Step 2 : Add 5 on both sides.
x = 4.5 + 5
x = 9.5
Value of x in fraction = 95/10 = 19/2
Value of x in decimal = 9.5

The rectangular floor of a classroom is 36 feet in length and 28 feet in width. a scale drawing of the floor has a length of 9 inches. what is the perimeter, in inches, of the floor in the scale drawing?
The perimeter of the floor in the scale drawing is 32 inches.
Using ratio and proportion, determine the width of the scale drawing of the floor.
actual length / scale length = actual width / scale width
36 feet / 9 inches = 28 feet / scale width
scale width = 28 feet (9 inches / 36 feet)
scale width = 7 inches
Perimeter is defined as distance around a two-dimensional shape.
The perimeter of a rectangle can be calculated using the formula below.
P = 2(l + w)
where P = perimeter
l = length
w =width
Plug in the values of the dimension of the scale drawing and determine its perimeter.
P = 2(l + w)
P = 2(9 inches + 7 inches)
P = 32 inches

if a 5-card poker hand is dealt from a well-shuffled deck of 52 cards, what is the probability of being dealt a two pair (2 cards of the same rank and 2 cards of any other rank with an unmatched card)?
Answer: 0.4754
A poker hand is a combination of 5 cards from the pack of 52 cards.
One hand full is said when we have 2 cards of the same rank.
In this question, we have to find the probability of 2 hands full of different ranks.
So,
We use the formula : C(n,k)=\frac{n!}{k!(n-k)!}
From permutations and combinations, since order doesn't exist.
From a suit of 13 cards any two cards are chosen:
C(13,2)=\frac{13!}{2!(13-2)!}
C(13,2)=\frac{13×12×11!}{2!11!}
C(13,2)=\frac{13×12!}{2!}
C(13,2)=156/2
C(13,2)=78
78 ways are there to choose for each of the pairs .
Now,
If one of the ranks is of any particular suit or maybe a face card out of which two of them are chosen.
C(4,2)=\frac{4!}{2!(4-2)!}
C(4,2)=6
And same for the other sets of cards of another pair.
We have 78×6×6= 2808 ways to pick the first 4 cards.
Now,
For the fifth card which can be any card except for the paired suit i.e, 13-2=11
There are 4 suits to pick from, 4×11= 44 cards to pick for the final card.
For the first card = 2080
For the fifth card= 44
Total number of two pair hands possible= 2080×44= 123,552
Out of:
C(52,5)=\frac{53!}{5!(52-5)!}
C(52,5)= 2,598,960
Probability of event= 123,552/2,598,960
= 0.4753901560624
Final answer= 0.4754

The probability of being dealt a two-pair is 0.4754.
Given;
What is the likelihood of receiving a two-pair when dealing a five-card poker hand from a 52-card deck that has been properly shuffled?
We use combinations to solve the given case;
From each suit, any two cards are chosen,
C(13,2) = [tex]\frac{13!}{2!(13-2)!}[/tex]
= [tex]\frac{13*12*11!}{2!11!}[/tex]
= 156/2
= 78
Hence, there are 78 ways to choose for each of the pairs.
Now,
If one of the ranks is a face card, two of them are chosen, or if one of the ranks is a certain suit.
C(4,2) = [tex]\frac{4!}{2!(4-2)!}[/tex]
=6
Similar to the other sets of cards of another pair.
We have 78×6×6= 2808 ways to pick the first 4 cards.
Now,
The fifth card, which can be any card other than the paired suit, is dealt as follows: 13 - 2 = 11.
There are 44 cards total to choose from among the 4 suits, or 4 x 11.
2080 for the primary card.
44 for the fifth card.
Possible two-pair hands total 2080 x 44 = 123,552.
Then,
C(52,5) = [tex]\frac{53!}{5!(52-5)!}[/tex]
= 2,598,960
Probability of event = Possible two-pair hands / Total outcome
= 123,552 / 2,598,960
= 0.47539
Hence, the probability of being dealt a two-pair is 0.4754.

GEOMETRY A triangle has vertices at (a,0), (b,4), and (c,0), where a
The expression that represents the area of the triangle is given as follows:
A = (c - a)[8 - (c - a)]/4.
How to obtain the area of a triangle?The area of a triangle is obtained as half the multiplication between the base b and the height h, that is:
A = 1/2 x b x h.
For the triangle in this problem, the base is composed by these following vertices:
(a, 0).(c, 0).Hence the length of the base is of:
b = c - a.
The height is given by the difference between the y-coordinate of the vertex (b,4) and the midpoint of the base ac, hence:
h = 4 - (c - a)/2 = [8 - (c - a)]/2
Hence the area is given as follows:
A = 1/2 x (c - a) x [8 - (c - a)]/2
A = (c - a)[8 - (c - a)]/4.

Step-by-step explanation: Use the rule of three (mathematic).
Using technology, calculate the weighted mean of the rors for each portfolio. based on the results, which list shows a comparison of the overall performance of the portfolios, from best to worst? portfolio 3, portfolio 1, portfolio 2 portfolio 2, portfolio 3, portfolio 1 portfolio 1, portfolio 2, portfolio 3 portfolio 3, portfolio 2, portfolio 1
Option B is the correct choice.
Based on the findings, the following list compares the portfolios' overall performances, ranking them from best to worst:
Portfolios 2, 3, and 1, respectively.
The weighted average ROR is calculated by adding the rates of return on the portfolio's assets and the percentage of the portfolio that is invested in each investment.
For Portfolio 1:
Total Investment= $700 + $2575 + $220 + $1000 + $1430 = $5925
Therefore, total investment = $5,925
Weighted Average ROR= (-3.8% * $700) / $5925 + (2.1% * $2575) / $5925 + (11.3% * $220) / $5925 + (5.8% * $1000) / $5925 + (1.6% * $1430) / $5925
WAROR = (-0.0045) + 0.0091 + 0.0042 + 0.0098 + 0.0039 = 0.0225
Therefore, the Weighted Average ROR= 2.25% (third)
For Portfolio 2:
Total Investment = $1250 + $1700 + $1515 + $1345 + $1,675 = $7485
Therefore, Total Investment = $7,485
Weighted Average ROR = (-3.8% * $1250) / $7485 + (2.1% * $1700) / $7485 + (11.3% * $1515) / $7485 + (5.8% * $1345) / $7485 + (1.6% * $1,675) / $7485
= (-0.0063) + 0.0048 + 0.0229 + 0.0104 + 0.0036 = 0.0354
Therefore, the Weighted Average ROR = 3.54% (first)
For Portfolio 3:
Total Investment = $1025 + $500 + $790 + $250 + $2500 = $5065
Therefore, Total Investment = $5,065
Weighted Average ROR = (-3.8% * $1025) / $5065 + (2.1% * $500) / $5065 + (11.3% * $790) / $5065 + (5.8% * $250) / $5065 + (1.6% * $2,500) / $5065
= (-0.0077) + 0.0021 + 0.0176 + 0.0029 + 0.0079 = 0.0228
Therefore, Weighted Average ROR = 2.28% (second)
Therefore, the correct order of portfolios based on the performance from best to worst will be:
Portfolio 2, Portfolio 3, and Portfolio 1. (Option B)

Flour = 300 gSugar = 150 gWater = 0.75 LFirst convert the mass of the water to the same SI units as the other ingredients.
1 liter = 1000 g
⇒ Water = 0.75 liters = 750 g
Total mass of the mixture:
= flour + sugar + water
= 300 g + 150 g + 750 g
= 1200 g
Therefore, the flour to total mass ratio is:
⇒ Flour : total mass = 300 : 1200 = 1 : 4

in the construction of confidence intervals, if all other quantities are unchanged, an increase in the sample size will lead to a
If all other values remain constant, an increase in sample size will result in a broader confidence interval when constructing one.
The definition of the MoE, or margin of error, is
MoE = sigma ÷ sqrt(n)
The population standard deviation is represented by sigma. If you don't know sigma, utilize s to get a rough idea of it. The sample standard deviation is denoted by the variable s.
The MoE increases along with the sigma. The width or narrowness of the confidence interval is directly determined by the MoE. A smaller MoE indicates greater confidence with less error, whereas a larger MoE indicates greater net casting but increased error.

Answer:
∆JGF ≅ ∆GJH by the SAA Postulate
Step-by-step explanation:
Given a figure showing two triangles with a common side, and two marked angles not at either end of that side, you want to know the applicable congruence postulate.
SAAThe letters S and A in the congruence postulate references refer to "Side" and "Angle". The sequence of the letters corresponds to the sequence of corresponding parts in the triangles.
In the given figure, two angles in each triangle are marked with a single arc and a double arc. The triangles share a side that has the double-arc angle at one end. Hence, the sequence of corresponding parts can be seen to be (common) Side - (double-arc) Angle - (single-arc) Angle. The SAA congruence postulate applies.
