[tex]8x^2+x+3[/tex]

Step-by-step explanation:

[tex](4x^2+1)+(4x^2+x+2)=\\4x^2+1+4x^2+x+2=\\4x^2+4x^2+x+1+2=\\8x^2+x+1+2=\\8x^2+x+3[/tex]

The solution is Option A.

The value of the polynomial equation is A = 8x² + x + 3

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = ( 4x² + 1 ) + ( 4x² + x + 2 )   be equation (1)

On simplifying the equation , we get

A = ( 4x² + 4x² ) + x + ( 1 + 2 )

On further simplification , we get

A = 8x² + x + 3

Therefore , the value of A is 8x² + x + 3

Hence , the equation is A = 8x² + x + 3

Answer:

The correct answer is option B. AA

Step-by-step explanation:

Given two triangle:

[tex]\triangle ABC[/tex]  and [tex]\triangle WXY[/tex].

The dimensions given in [tex]\triangle ABC[/tex] are:

[tex]\angle A = 27^\circ\\\angle B = 90^\circ[/tex]

We know that the sum of three angles in a triangle is equal to [tex]180^\circ[/tex].

[tex]\angle A+\angle B+\angle C = 180^\circ\\\Rightarrow 27+90+\angle C=180^\circ\\\Rightarrow \angle C = 63^\circ[/tex]

The dimensions given in [tex]\triangle WXY[/tex] are:

[tex]\angle Y = 63^\circ\\\angle X = 90^\circ[/tex]

We know that the sum of three angles in a triangle is equal to [tex]180^\circ[/tex].

[tex]\angle W+\angle X+\angle Y = 180^\circ\\\Rightarrow \angle W+90+63=180^\circ\\\Rightarrow \angle W = 27^\circ[/tex]

Now, if we compare the angles of the two triangles:

[tex]\angle A = \angle W = 27^\circ\\\angle B = \angle X= 90^\circ\\\angle C = \angle Y= 63^\circ[/tex]

So, by AA postulate (i.e. Angle - Angle) postulate, the two triangles are similar.

[tex]\triangle ABC \sim \triangle WXY[/tex] by AA theorem.

So, correct answer is option B. AA

Answer:

  g + 13 = 76

Step-by-step explanation:

We are told to use the variable "g" for the number of gallons of gas in the tank. When we add 13 to that, we are told the sum is 76. When all numbers are in gallons, this translates to ...

  g + 13 = 76

Answer:

b=5V2

Step-by-step explanation:

Area =31 1/4 = b*12.5 sin45/2=b*12.5*V2/2* 1/2=12.5V2/4 *b

(31*4+1)/4=125/4

so 125/4= 12.5V2*b/4

12.5V2*b=125

b=125/12.5V2=10/V2=10V2/2=5V2

Answer:

a) Probability of a day with temperature in the 70s = 0%

b) The set of the intersection of Tuesdays and days with temperature in the 80s is an empty or null set.

c) Probability an observation picked at random is both a Sunday and more than 90 degrees

= 0.10 = 10%

Step-by-step explanation:

The table of data for this question was obtained online and attached to this solution

Note that the probability of an event is defined as the number of elements in that event divided by the Total number of elements in the sample space.

a) What is the probability a day in the 70s is a Monday?

Of the days with temperature in the 70s (only one day, which is a Sunday), none of them are Mondays, hence, the probability of a day with temperature in the 70s being a Monday is 0%.

b) Which set forms the intersection of Tuesdays in the 80s?

Acvording to the data available, the set of Tuesdays with temperatures in the 80s is an empty set. Hence, this set is a null set.

c) What is the probability an observation picked at random is both a Sunday and more than 90 degrees?

The number of Sundays with temperature more than 90 degrees = 3

The total number of observations available = 30

Probability an observation picked at random is both a Sunday and more than 90 degrees = (3/30) = 0.10 = 10%

Correct question is;

A bag contains 10 counters. 6 of them are white. A counter is taken at random and not replaced. A second counter is taken out of the bag at random. Calculate the probability that only one of the two counters are white

Answer:

probability that only one of the two counters is white = 8/15

Step-by-step explanation:

To solve this question, first of all, let's look at probability we would have to either draw two white counters or two non-white counters (4/10 * 3/9).

Probability(draw 2 white counters) = (6/10 × 5/9) = 30/90 = 1/3

Probability(draw 2 non-white counters) = (4/10 × 3/9) = 2/15

Now, In all other cases, we'll draw exactly one white and one non-white counter, so the odds of this would be;

P(one white counter and one non-white counter) = 1 - [1/3 + 2/15)

= 1 - 7/15 = 8/15

arc UTR = 212°

Step-by-step explanation:

The measure of an arc is congruent to the central angle subtended by the arc, thus

arc UT = 90° , arc TS = 90° and arc SR = 32°

arc UTR = UT + TS + SR = 90° + 90° + 32° = 212°

Answer:

Since we want to satisfy both at the same time, "x" must be equal or greater than 6.

Step-by-step explanation:

This product is formed by two square roots, since this mathematical operator can only be defined for positive values and zero, the number inside the root must be always greater or equal to 0, on both roots. Therefore:

[tex]x - 6 \geq 0\\x \geq 6[/tex]

and

[tex]x + 3 \geq 0\\x \geq -3[/tex]

Since we want to satisfy both at the same time, "x" must be equal or greater than 6.

Answer:

P = 11/135 = 0.0815

Step-by-step explanation:

we can said that:

So, there are 124 people that use the gym, the pool or the track. This is calculated using the information above as:

14 + 18 + 21 + 22 + 14 + 16 + 19 = 124

Finally, there are 11 ( 135 - 124 = 11 ) people that don't use any facility, so the probability that a person doesn't use any facility is:

P = 11/135 = 0.0815

Answer:

Let's solve your inequality step-by-step.

[tex]\frac{x}{3}-(\frac{x-1}{2})\geq1[/tex]

Step 1: Simplify both sides of the inequality.

[tex]\frac{-1}{6}x+\frac{1}{2}\geq1[/tex]

Step 2: Subtract 1/2 from both sides.

[tex]\frac{-1}{6}x+\frac{1}{2}-\frac{1}{2}\geq1-\frac{1}{2}[/tex]

[tex]\frac{-1}{6}x\geq\frac{1}{2}[/tex]

Step 3: Multiply both sides by 6/(-1).

[tex](\frac{6}{-1})*(\frac{-1}{6}x)\geq(\frac{6}{-1})*(\frac{1}{2})[/tex]
