Answer:

?????

Step-by-step explanation:

The value of the expression when m = 3 is 13/15. So option(2) is correct.

The equation is defined in its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, x + 3 = 4 is an equation, in which x + 3 and 4 are two expressions separated by an 'equal' sign.

Given the expression as shown below:

2/5 m - 1/3

If m is equal to 3, then the expression will be;

2/5(3) - 1/3

6/5 - 1/3

Find the LCM

6/5 - 1/3 = 3(6)-5/15

6/5 - 1/3 = 18-5/15

6/5 - 1/3 = 13/15

Therefore the value of the expression if m = 3 is 13/15

Answer:

70 km/hr

Step-by-step explanation:

The probability is 0.00332.

From the given question,

Danny Nguyen has A 7 and opponent has A K+.

The flop is : 5 K 5

As there are two players playing the remaining cards in the deck will be (52 - 2 - 2 - 3 -1(burn)) = 44

For Nguyen to win he needs two of the three 7's left in the deck for turn and river.

For turn we have to select a 7 from the three 7's and for river we have to select a 7 of the remaining two 7's.

So the probability is

P = [tex]\frac{\binom{3}{1}}{\binom{43}{1}}*\frac{\binom{2}{1}}{\binom{41}{1}}[/tex]

P = 0.00332

Step-by-step explanation:

The trinomial and binomial form of the incomplete algebraic expression is [tex]d^{2}[/tex] -3d + 9/4 and [tex](d-\frac{3}{2}) ^{2}[/tex]

A perfect square is a quadratic expression that factors into two identical binomials.

For example, if you multiply these two identical binomials factors:

(x + 2)(x + 2)

to complete the square in the expression [tex]d^{2}[/tex] -3d, we square the half of the coefficient of d which is -3/2

so the expression becomes,

[tex]d^{2}[/tex] -3d + [tex](\frac{-3}{2}) ^{2}[/tex] = [tex]d^{2}[/tex] -3d +[tex]\frac{9}{4}[/tex]

The Binomial form of the expression [tex]d^{2}[/tex] -3d + [tex](\frac{-3}{2}) ^{2}[/tex]

can be written by take [tex]d^{2}[/tex] term and the constant and putting them in a bracket and squaring

which becomes

[tex](d - \frac{3}{2} )^{2}[/tex]

In conclusion, the trinomial form of the expression is [tex]d^{2}[/tex] -3d +[tex]\frac{9}{4}[/tex] while the Binomial form of the expression is [tex](d - \frac{3}{2} )^{2}[/tex]

When corresponding angles are congruent, the lines are parallel

Congruent angles are two or more angles that are identical to each other. Thus, the measure of these angles is equal to each other. The type of angles does not make any difference in the congruence of angles, which means they can be acute, obtuse, exterior, or interior angles. The angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.

Examples of the corresponding angle are any angles which are formed on the opposite side of the transversal. Now, it should be noted that the transversal can intersect either two parallel line or two non-parallel lines. Thus, corresponding angles can be of two types:

Corresponding angles formed by parallel lines and transversals

Corresponding angles formed by non-parallel lines and transversals

Looking at the image, angle I is congruent to each other. Angle II is congruent with each other as well as angle III.

When corresponding angles are congruent, the lines connecting them must be parallel. This is the only valid or correct options in the task.

The speed of slower bus is 118 km/hr and speed of faster bus is 133 km/hr

Speed is a scalar quantity that refers to "how fast an object is moving".

Given that, two buses leave a station at the same time and travel in opposite directions, one bus travels 15 km/h faster than the other, the two buses are 1004 kilometres apart after 4 hours,

Speed = distance/ time

Let the speed of the slower bus be v and the faster bus be (v+15)

According to the question,

vt + (v+15)t = 1004

vt + vt + 15t = 1004

t = 4

4v + 4v + 60 = 1004

8v = 944

v = 118

Hence, The speed of slower bus is 118 km/hr and speed of faster bus is 133 km/hr

The total profit that the company would make on the trip can be found to be £7,320

The revenue that the company makes would be:

= Number of passengers x Amount that each passenger pays

= 400 x 23

= £9, 200

Each coach takes 50 passengers so the number of coaches needed are:

= 400 passengers / 50 passengers per coach

= 8 coaches

The total cost to the company for the trip is:
= (Number of coaches x Driver cost per coach) + (Number of coaches x Fuel per mile x Distance traveled for each coach)

= ( 8 x 95) + ( 8 x 70p x 200)

= 760 + 112, 000 p

= 760 + 112, 000/ 100 pence per pound

Answer: I am not sure if you're accustomed to using a z-score and table of probabilities or technology, so I will answer using both!

a) Since you're choosing one person from the population, you will use the mean and standard deviation from the population.  z= (210.9-197.5)/8.6 = 1.56 Using a table of normal probabilities,

P(x>210.9)= 1-P(z<1.56)= 1- 0.9406=0.0594

Using technology: normalcdf(210.9, 1E99, 197.5, 8.6)=0.0596

b) Since you're calculating the population for a sample to occur, you need to get a mean of the sampling distribution and standard deviation of the sampling distribution.

Meanpop=Meansampling dist.=197.5

St. Devsampling dist.= Stdpopulation/√n = 8.6/√15 = 2.22

Using technology, P(X>196.20)= normalcdf( 196.20, 1E99, 197.5, 2.22) = 0.7209

c) You only have to worry about the sample size in a sampling distribution if you either do not know the shape of the distribution of the population or if the distribution of the population is not normally distributed. Since this population is normally distributed (as stated in the given information), then your sample size does not have to be greater than 30.

Answer:

[tex]f(x) = 2(x-9)^{2} + 3[/tex]

Step-by-step explanation:

In vertex form, (h, k) represents the vertex.

With the given vertex of (9, 3), h = 9 and k = 3. You can substitute those values into the equation.

In vertex form, a represents vertical stretch or compression.

In this case, since the parent function, x^2 is multiplied by 2, a = 2. You can substitute this into the equation.

Answer: Minimum cost = $264

Paint left over = 7/8 qt

Step-by-step explanation:

6 gal covers 1920 sf (6 gal x 320 sf/gal)

6 gal x $29/gal = $174

2250 sf - 1920 sf = 330 sf

Need 4.125 qt to cover 330 sf, but you can't buy a partial quart

5 qt x $18/qt = $90

Total cost = $174 + $90 = $264

You have 7/8 qt left over

The probabilities, using the Poisson distribution, are given as follows:

a) Two earthquakes in a year: 0.0446 = 4.46%.

b) No earthquakes in two consecutive months: 0.3679 = 36.79%.

c) No earthquakes in two consecutive months, given that there were no earthquakes in the previous month: 0.3679 = 36.79%.

The Poisson distribution is used when we only have the mean in a given interval and the mass function is given as follows:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

The parameters are listed as follows:

For one year, the mean number of earthquakes is given as follows:

[tex]\mu = 6[/tex]

The probability of exactly two earthquakes in a year is obtained as follows:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 2) = \frac{e^{-6}6^{2}}{(2)!} = 0.0446[/tex]

For two months, the mean is given as follows:

[tex]\mu = 2 \times 6 \times \frac{1}{12} = 1[/tex]

For items b and c, the probabilities are the same, P(X = 0), as the events are independent, hence:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-1}1^{0}}{(0)!} = 0.3679[/tex]

It is defined as a function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a×

where a is a constant and a>1

The exponential function is of the form:

y = ab×

Plug x = 0 and y = 1200

1200 = a

Plug x = 2, y = 675, and a = 1200

675 = 1200(b)²
