Answer:

0.03

Step-by-step explanation:

Given data

Probability that it will rain on Sunday= 0.7

Probability that it will rain on Monday = 0.2

Firstly we need to solve for the probability that it will rain on Tuesday

Sample space S = number of week days = 7

Probability that I will rain on Tuesday = 1/7= 0.14

Hence the probability that it rains on BOTH Monday and Tuesday= 0.2*0.14= 0.028

Rounding up the nearest hundredths = 0.03

Answer:

N(h) = 2h + 6

Step-by-step explanation:

A model of the number of people that Denis can invite to his party:

N(x) = x/25.............(1)

Where x = amount of money saved

Amount of money saved can be modeled by the equation:

M(h) = 50h + 150...........(2)

In the above model, h = number of overtime hours

M(h) = amount of money saved = x

Therefore equation (1) can be re - written as:

N(x) = M(h)/25.................................(3)

Substituting equation (2) into equation (3)

[tex]N(h) = \frac{50h + 150}{25} \\N(h) = \frac{50h}{25} + \frac{150}{25} \\N(h) = 2h + 6[/tex]

Find an explicit expression that models the number of people that Denis can invite to his party if he worked h  overtime hours this week can be expressed as:

N(h) = 2h + 6

Length KN = 2π/3 = 2.094

Step-by-step explanation:

Length KN = (mKN/360)2πr

Length KN = (40/360)2π3

Length KN = (1/9)6π

Length KN = 6π/9

Length KN = 2π/3 = 2.094

Answer: x = 20.

Step-by-step explanation:

x and (3x + 10) combine to form a right angle, shown in the diagram by the small square joining the perpendicular lines.

Right angles are 90 degrees, so you can add both angles to get 90:

[tex]x + (3x + 10) = 90\\\\4x + 10 = 90\\\\4x = 80\\\\x = 20[/tex]

Answer:

LAST ONE IS angle JLK congruent to angle LNM, SAS

Step-by-step explanation:

The triangles JLK and LMN are similar by SAS congruence theorem, LJK≅ LNM.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

The triangles JLK and LMN are similar triangles.

Which means the sides are proportional and those angles are congruent.

We have to prove that JLK is similar to LMN.

By SAS rule we have "if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar".

So LJK≅ LNM.

Let x represent the speed of of boat.

We have been given that the river current is 3 miles per hour.  

The speed of boat upstream will be [tex]x-3[/tex].

The speed of boat downstream would be [tex]x+3[/tex].

[tex]\text{Time}=\frac{\text{Distance}}{\text{Speed}}[/tex]

We have been given that you travel 2 miles downstream to a marina for supplies, and then you travel 3 miles upstream to a dock.

We can represent this information in an equation as:

[tex]\text{Time}=\frac{2}{x+3}+\frac{3}{x-3}[/tex]

Since the speed of the boat is 18 miles per hour, so we will substitute [tex]x=18[/tex] in above equation and solve for time.

[tex]\text{Time}=\frac{2}{18+3}+\frac{3}{18-3}[/tex]

[tex]\text{Time}=\frac{2}{21}+\frac{3}{15}[/tex]

[tex]\text{Time}=\frac{2}{21}+\frac{1}{5}[/tex]

[tex]\text{Time}=\frac{2\cdot 5}{21\cdot 5}+\frac{1\cdot 21}{5\cdot 21}[/tex]

[tex]\text{Time}=\frac{10}{105}+\frac{21}{105}[/tex]

[tex]\text{Time}=\frac{31}{105}[/tex]

[tex]\text{Time}=0.295238095[/tex]

Since time is in hours, so let us convert our given time in minutes.

1 hour = 60 minutes.

[tex]\text{Time}=0.295238095\times 60\text{ minutes}[/tex]

[tex]\text{Time}=17.7142857\text{ minutes}[/tex]

Rounding to nearest tenth of minute.

[tex]\text{Time}\approx 17.7\text{ minutes}[/tex]

Therefore, it will take approximately 17.7 minutes for the boat to take the trip.

Step-by-step explanation:

X-AXIS

when a graph intersects the x-axis, the y value is always 0.  

Ex.  Points (1,0), (-5,0), (-3,0), (6,0), etc. are all on the x-axis because y = 0.  

to find where the graph crosses the x-axis, let y or g(x) = 0

0 = -5^x + 5  subtract 5 from both sides

-5 = -5^x       if x is 1, that would produce -5 = -5

(1,0) x axis

Y-AXIS

when a graph intersects the y-axis, the x value is always 0.

Ex.  Points (0, 1), (0, -2), (0, 3), etc. all lie on the y-axis because x = 0.

to find where teh graph crosses the y-axis, let x = 0

does the exponent "x" apply to (-5) or just 5?  

[tex]-5^{x} or (-5)^{x}[/tex]

(-5)^0 + 5    any number with a 0 power is 1

1 + 5 = 6

(0, 6)

       -1  +  5 = 4

See Explanation and Attachment

Step-by-step explanation:

Your question is incomplete as the diagram of the polygon is not attached.

However, I'll give a general guide to calculate the area of a regular polygon.

If you apply these steps, you'll be able to solve your question.

The area of a regular polygon is calculated this.

Area = ½ap

Where a represents the apothem of the polygon and p represents the perimeter of the polygon.

The term "apothem" means the distance between the centre of the polygon and the base of the polygon.

Take for instance, the attachment below.

The polygon is a regular hexagon (it has 6 sides)

The apothem, a = 8.2 ft

The perimeter, p = The sum of all sides of the hexagon

p = (7.6 + 7.6 + 7.6 + 7.6 + 7.6 + 7.6)ft

p = 45.6 ft

Hence, the area of the polygon

A = ½ap becomes

A = ½ * 8.2 * 45.6

A = ½ * 373.92

A = 186.96ft²

Answer:

an = 56-8(n-1)

Step-by-step explanation:

This is an arithmetic sequence

The common difference is 48 - 56 =-8

a1 = 56

an = a1+d(n-1)

an = 56-8(n-1)

The region of integration in the xy-plane for the given integral ∫∫R √(4xy) dy dx, where R is the region bounded by x = 0, x = -3, y = 0, and y = -9 - x^2, can be visualized as a triangular region in the first quadrant.

The given integral is a double integral of the function √(4xy) over a specific region in the xy-plane. To determine the region of integration, we consider the given bounds: x ranges from 0 to -3, and y ranges from 0 to -9 - x^2.

Starting with the x bounds, x = 0 represents the y-axis, while x = -3 represents a vertical line passing through the point (-3, 0). Thus, the region is bounded by the y-axis on the left and the vertical line x = -3 on the right.

Moving on to the y bounds, y = 0 represents the x-axis, while y = -9 - x^2 represents a downward-opening parabola with its vertex at the origin and its axis of symmetry parallel to the y-axis. Since y is negative, the parabola lies below the x-axis.

By combining the x and y bounds, we obtain a triangular region in the first quadrant. The triangle is formed by the x-axis, the line x = -3, and the curve y = -9 - x^2. This region of integration represents the area over which the function √(4xy) is being integrated.

Step-by-step explanation:

Answer: The model indicates that students who have spent 0 hours playing sports will have an average mood rating of 5

Step-by-step explanation:

A y-intercept of 5 means players spending 0 hours playing sports will have an average rating of 5.

Linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables.

In this case, y is the rating of the mood on a scale from 0 to 10 while the x represents the number of hours in playing sports.

We know the y-intercept means the x-coordinate is 0 means the number of hours spent playing sports is 0.

So, a y-intercept of 5 means students who have spent 0 hours playing sports will have an average mood rating of 5.

Hence, a y-intercept of 5 means players spending 0 hours playing sports will have an average rating of 5.
