Answer:

The total area of the fields that Ram has is  170,900 square meters ( 170900 m²)

From the question, we are to determine the total area of the fields that Ram has

Since the fields are square in shapes, we will use the formula for calculating the area of a square

The area of a square can be calculated by using the formula,

A = s²

Where A is the area

and s is the side

For the first field

s = 350 m

∴ A = 350²

A = 122500 m²

For the second field

s = 220 m

∴ A = 220²

A = 48400 m²

Then,

The total area of the fields = 122500 m² + 48400 m²

The total area of the fields = 170900 m²

Hence, the total area of the fields that Ram has is  170,900 square meters ( 170900 m²)

Using it's concept, it is found that the desired probability is given as follows:

P(Head, Diamond AND Head, Heart) = 1/64.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, for each trial, there are 8 equally as likely outcomes, hence:

Hence the probability of both outcomes is given by:

P(Head, Diamond AND Head, Heart) = 1/8 x 1/8 = 1/64.

Step-by-step explanation:

Answer:

(x - 6)(x - 3)

Step-by-step explanation:

x² - 9x + 18

consider the factors of the constant term (+ 18) which sum to give the coefficient if the x- term (- 9 )

the factors are - 6 and - 3 , since

- 6 × - 3 = + 18 and - 6 - 3 = - 9 , then

x² - 9x + 18 = (x - 6)(x - 3) ← in factored form

Answer:

(x - 3)(x - 6)

Step-by-step explanation:

x²- 9x+18

= x^2 - 6x - 3x + 18

= x(x - 6) - 3(x - 6)

= (x - 3)(x - 6).

If the probability will be 0.7842. Then the number of students who scored between 200 and 245 will be 941.

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The scores of a recent test taken by 1200 students had an approximately normal distribution with a mean of 225 and a standard deviation of 18.

Then the number of students who scored between 200 and 245 will be

Then the z-score for x = 200

[tex]z = \dfrac{200-225}{18}\\\\z = -1.389[/tex]

Then the z-score for x = 245

[tex]z = \dfrac{245-225}{18}\\\\z = 1.1111[/tex]

Then we have

[tex]\begin{aligned} P(-1.39 < z < 1.11) &= P(z < 1.11) - P(z < -1.389)\\\\&= P(z < 1.11)- [1-P(z > -1.389)] \\\\&=0.8665 - (1-0.9177) \\\\&=0.7842 \end[/tex]

Then the number of students who scored between 200 and 245 will be

→ 0.7842 × 1200

→ 941.04 ≅ 941

Answer: I will give you a answer for both of them.

Step-by-step explanation:

First equation: x+y=20

1. Subtract y from both sides.

x=20−y

Second equation: 2x+y=25

1. Subtract y from both sides.

2x=25−y

Answer:

∠V = 32°

Step-by-step explanation:

VW = UV

⇒ Isosceles triangle. So, the angles opposite sides are equal.

∠W = ∠U

∴ ∠W = ∠U = 74°

 Sum of all angles of triangle = 180

74 + 74 + ∠V = 180

       148 + ∠V = 180

                ∠V = 180 - 148

∠V = 32°

Answer:

Hence, slope of y=7x−2 is 7 and y -intercept is −2.

Step-by-step explanation:

The equation of any straight line can be written as y=mx+c, where m is its slope and c is its y-intercept.

Comparing the equation y=7x−2 with the standard form of the equation, we get:

m=7,c=−2

Hence, slope of y=7x−2 is 7  and y -intercept is −2

Hope this helps :)

The solution set of the equation is (0, 7)(-1, 6)

y = x² + 2x + 7

y = x + 7

y = x² + 2x + 7

y = x + 7

x² + 2x + 7 = x + 7

x² + 2x - x + 7 - 7 = 0

x² + x = 0

x(x + 1) = 0

Therefore,

x = 0 and x = -1

Substitute the value in equation(ii)

when x = 0

y = x + 7

y = 0 + 7

y = 7

when x = -1

y = -1 +7

y = 6

Therefore, the solution set are (0, 7)(-1, 6)

The roots of the equation [tex]x^{2}[/tex]-15x +2 =0 are 14.865 and 0.135

Completing the square method is one of the methods to find the roots of the given quadratic equation.

Given equation is:

[tex]x^{2}[/tex]-15x +2 =0

Using Completing the Square method we have

[tex]x^{2}[/tex]-15x +2 + [tex](\frac{15}{2})^{2}[/tex] - [tex](\frac{15}{2})^{2}[/tex] =0

Now,

[tex]x^{2}[/tex]-15x + [tex](\frac{15}{2})^{2}[/tex] - [tex](\frac{15}{2})^{2}[/tex] +2=0

or, [tex][x-(\frac{15}{2})]^{2}[/tex] - 225/4 +2 =0

or,  [tex][x-(\frac{15}{2})]^{2}[/tex] -217*4 =0

or,  [tex][x-(\frac{15}{2})]^{2}[/tex] = 217/4
