I believe the area of that polygon is 473 square feet because to find the area of the odd corner you have to look at the differences between the different side lengths, so 2*5=10 and then you have to divide 10 by 2 because only half of that corner is there.

Option D: x \geq 3 is the solution

Explanation:

The given expression is 3 x-1 \geq 8

We need to determine the solution of the expression.

<u>Solution:</u>

The solution of the expression can be determined by solving the expression for the variable x.

Thus, we have,

3 x-1 \geq 8

Adding both sides of the expression by 1, we get,

3x\geq 9

Dividing both sides of the expression by 3, we get,

x \geq 3

Thus, the solution of the expression is x \geq 3

Hence, Option D is the correct answer.

Ten cards numbered 1 through 10 are mixed together and then one card is drawn. Find the probability of each event. Write each an
liraira [26]

Answer:

2/5, 0.4, 40%

7/10, 0.7, 70%

1/2, 0.5, 50%

1/2, 0.5, 50%

4/5, 0.8, 80%

3/5, 0.6, 60%

3/10, 0.3 ; 30%

Step-by-step explanation:

Sample space = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

P(less Than 5) :

Required = (1, 2, 3, 4) = 4 observations

P(less than 5) = 4 / 10 = 2 / 5 = 0.4 = 40%

Greater than 3) = (4, 5,6,7,8,9,10) = 7 observations

P greater Than 3) = 7/10 = 0.7 = 70%

Odd = (1,3,5,7,9) = 5

P(odd) = 5 / 10 = 1/2 = 0.5 = 50%

(even) = (2,4,6,8,10) = 5

P(even) = 5 / 10 = 1/2 = 0.5 = 50%

Not a multiple of 4 = (1,2, 3,5,6,7,9,10) = 8

P(not A multiple of 4) = 8/10 = 4/5 = 0.8 = 80%

not 5, 6, 7, or 8 = (1,2,2,4,9,10).= 6

P(not 5, 6, 7, or 8) = 6 / 10 = 3/5 = 0.6 = 60%

Divisible by 3 = (3, 6, 9) = 3

P(divisible by 3). = 3/10 = 0.3 = 30%

_ _ _ _ _ _ _ _ _ _ _ _ _ equations usually will have two possible solutions
Anna007 [38]

Answer:

Quadratic

Step-by-step explanation:

This is because quadratic equations require a variable squared. Most numbers have two square roots, a positive and a negative. So, the implementation of (variable)² in an equation will most likely have x ± (variable) as an answer.

P (2, 3) and Q (6, 10) are two points on the Cartesian plane.
lara31 [8.8K]

Step-by-step explanation:

Given:

(x_1, \: y_1 ) =(2, \:3)\:\:\&\:\: (x_2, \: y_2) =(6, \:10)

l(PQ) =  \sqrt{ {(x_1 - x_2)}^{2} +  {(y_1 - y_2)}^{2}}  \\  \\  = \sqrt{ {(2 - 6)}^{2} +  {(3 - 10)}^{2}} \\  \\  = \sqrt{ {( - 4)}^{2} +  {( - 7)}^{2}}  \\  \\  =  \sqrt{16 + 49}  \\  \\  =  \sqrt{65}  \\  \\ \therefore \purple{ \boxed{  l(PQ) = 8.06 \: units}}\\\\

Let S be the mid-point of PQ.

\therefore S = \{\frac{x_1+x_2}{2}, \:\:\frac{y_1+y_2}{2}\} \\\\= \{\frac{2 +6}{2}, \:\:\frac{3+10}{2}\} \\\\= \{\frac{8}{2}, \:\:\frac{13}{2}\} \\\\\therefore S= \{4, \:\:6.5\} \\\\

Equation of line PQ is given as:

\frac{y-y_1}{y_1 - y_2}=\frac{x-x_1}{x_1 - x_2} \\\\\therefore  \frac{y-3}{3 - 10}=\frac{x-2}{2 - 6} \\\\\therefore  \frac{y-3}{-7}=\frac{x-2}{-4} \\\\\therefore  \frac{y-3}{7}=\frac{x-2}{4} \\\\\therefore 4(y-3)=7(x-2)\\\\\therefore 4y-12=7x-14\\\\\therefore 7x-14 - 4y + 12=0\\\\\red{\boxed {\therefore 7x-4y - 2 =0}}
