How to create a linear regression equation

The distance between points M and N according to the task content is; 9.8 meters.

From observation of the task content information; it can be deduced for a fact that the line segment MN which joins points M and N is parallel to the line JK. This follows from the fact that M and N are midpoints of KL and JL respectively.

Hence, it follows that triangles NLM and JLK are congruent and by the ratio of corresponding sides equality;

NM/19.6 = 7.4/(2×7.4)

NM = 19.6/2 = 9.8 meters.

This follows from congruence theorems in which case, the ratio of corresponding sides of congruent triangles are equal.

Step-by-step explanation:

[tex]x^2 + y^2 = 5/8 (1)\\\frac{4}{3}xy = \frac{1}{4} (2)\\\\\textrm {From (2) by multiplying both sides by 3/4 we get}\\\\xy = \frac{3}{16} (3)\\\textrm{We know that } (x + y)^2 = x^2 + 2xy + y^2 \\\textrm{Adding 2xy to the LHS and RHS of equation 1 gisues us }\\x^2 + y^2 + 2xy = \frac{5}{8} + 2 * \frac{3}{16} = \frac{5}{8} + \frac{3}{8} = \frac{8}{8} = 1[/tex]

The interest that Marcos will get is 50000.

The following can be deduced from the information given:

Principal = 50000

Interest rate = 12.5%

Time = 8 years

The simple interest will be:

= (PRT/100)

= (50000 × 12.5 × 8)/100

= 50000

The amount that will be obtained after 8 years will be:

= Principal + Interest

= 50000 + 50000

= 10000

Answer:

<PQR is 130 degrees

Step-by-step explanation:

When it says the line bisects the angle, that means the two smaller angles are equal to each other.

Therefore 3x+5 = 2x+25

Now rearrange to get x.

3x-2x=25-5

x=20

Now plug the x back into both phrases and them together to get the final answer for <PQR.

20 * 3 + 5 = 65

20 * 2 + 25 = 65

65*2 = 130

Answer:

8

Step-by-step explanation:

The equation of the parabola can be represented as

[tex]y = a(x + 1)(x - 5)[/tex]

for some constant a.

Since the coefficient of x² is 2, a = 2, so

[tex]y = 2(x + 1)(x - 5) \\ \\ y = 2( {x}^{2} - 4x + 5) \\ \\ y = 2 {x}^{2} - 8x + 10[/tex]

So, the answer is 8.

Using proportions, considering the given ratio, it is found that 9090 grapes were there.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The ratio of bananas to grapes of 3:101 means that out of 104 fruits, 3 are bananas and 101 are grapes. Hence the rule of three is given as follows:

3 bananas - 101 grapes

270 bananas - n grapes.

Applying cross multiplication:

3n = 101 x 270

n = 101 x 270/3

n = 9090.

9090 grapes were there.

Angle x of the triangle PQR is 53 degrees.

Angle x is gotten by alternate angle relationship.

Line AB is parallel to line CD

Therefore,

AB║CD

Hence,

62 + x = 115(alternate angles)

62 - 62 + x = 115 - 62

x = 53°

We got the angle x degrees from alternate angle relationship.

Answer:

x = 50

Step-by-step explanation:

Angle <BPR and angle <PRD are supplementary angles so their sum is equal to 180

m<BPR + 115 = 180 subtract 115 from both sides

m<BPR = 65

angles:

<APQ, x, and <BPR form a straight line and so their sum is equal to 180

65 + x + 65 = 180 add like terms

130 + x = 180 subtract 130 from both sides

x = 50

Based on the calculations, the area of this triangle is equal to: A. Area = 1/2 × [√(x₂² + y₂²) × √(x₁² + x₁²)].

Mathematically, the area of a triangle can be calculated by using this formula:

Area = 1/2 × b × h

Where:

Next, we would find the distance between points A and B:

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

AB = √[(x₂ - 0)² + (y₂ - 0)²]

AB = √(x₂² + y₂²)

Also, we would find the distance between points A and C:

Distance = √[(x₁ - x₂)² + (y₁ - y₂)²]

AC = √[(x₁ - 0)² + (y₁ - y0)²]

AC = √(x₁² + x₁²).

Now, we can find the area of this triangle:

Area = 1/2 × b × h

Area = 1/2 × AB × AC

Area = 1/2 × [√(x₂² + y₂²) × √(x₁² + x₁²)]

The amount Cindy should increase in each dimension of the scaled model is 12 m.  

It is defined as the six-faced shape, a type of hexahedron in geometry.

It is a three-dimensional shape. It is also called a cuboid.

We have:

The scaled model of the container has dimensions 2m by 4m by 6m.

Volume of the scaled model = 2×4×6 = 48 cubic m

Let x be the amount by which each dimension is increased.

(2 + x)(4 + x)(6 + x) = 84(48)

[tex]\rm 48+44x+12x^2+x^3=4032[/tex]

[tex]\rm x^3+12x^2+44x-3984=0[/tex]

[tex]\rm x-12=0\quad \mathrm{or}\quad \:x^2+24x+332=0[/tex]

The probability that the team will win the sport is 77%.

Given that an area kicker in pro football incorporates a 77% probability of creating a field goal over 40 yards and every attempt field goal is independent.

Probability is how something is likely to happen. The probability of a happening is calculated by the probability formula by simply dividing the favorable number of outcomes by the overall number of possible outcomes.

So, his team will win the sport if he makes a goal otherwise loses.

Therefore, the Probability that his team will win the sport P[E] =P[making a field goal]

P[E]=77%

Hence, the probability that the team will win the sport when making a field goal is 77%.

You have the correct answer. Apply a 180 degree rotation around the point (0,2)

Reason:

We'll connect corners between figures A and B.

Draw a line from the upper right corner of figure A to the lower left corner of figure B. This line is in red (see diagram below).

Draw another line from the lower right corner to the upper left corner. This line is in blue.

The red and blue lines intersect at the center of rotation (0,2)

The line segments constructed consist of endpoints of "before" and "after". For instance, the upper right corner in figure A rotates to the lower left corner of figure B. This happens because of the 180 degree rotation.

Note: You can do this rotation either clockwise or counterclockwise, and you would get the same result.

The expected value after 10 game at a carnival is 16.1 tickets.

Given the probabilities that bag lands into the outer ring, middle ring, center are 0.64, 0.11 and remaining. 1 ticket awarded for the outer, 2 for middle and 3 for middle.

We have to find the expected value we will get if we play the game 10 times.

Probability is the chance of happening an event among all the events possible. Value of probability lies between 0 and 1. The formula of probability is as under:

Probability=number of items/ total items in consideration.

Probability that bag lands in center is 1-0.64-0.11=0.25.

Expected value when game is played 1 time=1*0.64+2*0.11+3*0.25

=0.64+0.22+0.75

=1.61

Expected value when the game is played 10 times=10*1.61

=16.1 tickets.

Hence the expected value when game is played 10 times is 16.1 tickets.
