Answers

Answer 1

Answer:

b. (8, 3)

Step-by-step explanation:

[Linear System with Two Variables]

Given that:

y = 7x - 53y = -4x + 35

(i) Find the value of x

Substitute the value of y in -4x + 35 with 7x - 53

Therefore we get

7x - 53 = -4x + 35

-4x to the left side of "=" = + 4x

-53 to the right side of "=" = + 53

we get:

7x + 4x = 53 + 35

11x = 88

x = 8 ✅

(ii) Find the value of y

y = 7x - 53

put x = 8 after the coefficient = 7

y = 7·8 - 53

y = 56 - 53

y = 3 ✅

The value of (x, y) =

(8, 3) ✅

Option B

Answer 2
the answer would be c.
(8,3)

y=7x-53

(3)=7(8)-53
3=56-53
3=3

y=-4x+34

(3)=-4(8)+35
3=-32+35
3=3

I'm assuming you want to know what "x"is. If so then for the first one x is 1/7. For the second one x= 5. And the last one is x= 3.

Step-by-step explanation:

To check you just substitute what ever x equals into the equation so 35x+5=10 would be 35(1/7)+5=10 and it should equal 10=10, which means infinite solutions. If you were not trying to find out what x equals then what are you looking for exactly?

Which equation is equivalent to 3-4x=12

Answers

We have a linear equation here.

3 - 4x = 12

Subtract 3 from both sides.

3 - 3 - 4x = 12 - 3

-4x = 9

Divide both sides by -4 to find x.

-4x/-4 = 9/-4

x = -9/4

The value of solution of expression is,

⇒ x = - 9 / 14

WE have to given that;

A mathematical expression is,

⇒ 3 - 4x = 12

Now, WE can simplify as;

⇒ 3 - 4x = 12

Add 4x both side,

⇒ 3 - 4x + 4x = 12 + 4x

⇒ 3 = 12 + 4x

Subtract 12 both side, we get;

⇒ 3 - 12 = 14x

⇒ - 9 = 14x

⇒ x = - 9 / 14

Thus, The value of solution of expression is,

⇒ x = - 9 / 14

Use the following coordinate plane to write the ordered pair for each point.

Answers

Step-by-step explanation: When finding the coordinates

of a given point, be very careful with your signs.

On the x-axis, left means negative and right means positive and

on the y-axis, down means negative, and up means positive.

So to find the coordinates for point A, we start at the origin,

which is the point (0, 0), and we move 2 units to the left and 4 units up.

So that's the point (-2, 4).

Remember to go left or right first, then up or down.

So for point B, we go 0 units to the left or right and 3 units down.

So that's the point (0, -3).

For point C, we move 4 units to th

right and 4 units down so tha's (4, -4).

[tex]P(X=8) = 0.0194[/tex]

[tex]P(X \ge 8)= 0.9820[/tex]

[tex]P(X \ge 1)= 1[/tex]

[tex]P(X\le 1) = 0.0000049[/tex]

Step-by-step explanation:

Given

[tex]\lambda = 15[/tex]

Poisson distribution is given by:

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

Solving (a): 8 bugs

This implies that:

[tex]x = 8[/tex]

So, we have:

[tex]P(X=8) = \frac{15^8 * e^{-15}}{8!}[/tex]

[tex]P(X=8) = \frac{783.99418938}{40320}[/tex]

[tex]P(X=8) = 0.0194[/tex]

Solving (b): At least 8 bugs

This is represented as: [tex]P(X \ge 8)[/tex]

Using complement rule:

[tex]P(X \ge 8)= 1 - P(X<8)[/tex]

Where

[tex]P(X<8) = P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + P(X=6) + P(X=7)[/tex]

[tex]P(X<8) = \frac{15^1 * e^{-15}}{1!} + \frac{15^2 * e^{-15}}{2!} + \frac{15^3 * e^{-15}}{3!} + \frac{15^4 * e^{-15}}{4!} + \frac{15^5 * e^{-15}}{5!} + \frac{15^6 * e^{-15}}{6!} + \frac{15^7 * e^{-15}}{7!}[/tex]

[tex]P(X<8) = (\frac{15^1}{1!} + \frac{15^2}{2!} + \frac{15^3 }{3!} + \frac{15^4}{4!} + \frac{15^5}{5!} + \frac{15^6}{6!} + \frac{15^7}{7!}) e^{-15}[/tex]

[tex]P(X<8) = (15 + 112.5 + 562.5 + 2109.375 + 6328.125 + 15820.3125 + 33900.6696429) *e^{-15}[/tex]

[tex]P(X<8) = 58848.4821429 *e^{-15}[/tex]

[tex]P(X<8) = 0.0180[/tex]

So:

[tex]P(X \ge 8)= 1 - P(X<8)[/tex]

[tex]P(X \ge 8)= 1 - 0.0180[/tex]

[tex]P(X \ge 8)= 0.9820[/tex]

Solving (c): At least 1

This is represented as: [tex]P(X \ge 1)[/tex]

Using complement rule:

[tex]P(X \ge 1)= 1 - P(X<1)[/tex]

[tex]P(X<1) = P(X = 0)[/tex]

[tex]P(X<1) = \frac{15^0 e^{-15}}{0!}[/tex]

[tex]P(X<1) = \frac{e^{-15}}{1}[/tex]

[tex]P(X<1) = e^{-15}[/tex]

So:

[tex]P(X \ge 1)= 1 - P(X<1)[/tex]

[tex]P(X \ge 1)= 1 - e^{-15[/tex]

[tex]P(X \ge 1)= 0.99999969409[/tex]

[tex]P(X \ge 1)= 1[/tex]

Solving (d): Not more than 1

This implies at most 1.

It is represented as:

[tex]P(X\le 1)[/tex]

It is calculated using:

[tex]P(X\le 1) = P(X = 0) + P(X =1)[/tex]

[tex]P(X = 0) = e^{-15}[/tex]

[tex]P(X=1) = \frac{15^1 * e^{-15}}{1!}[/tex]

[tex]P(X=1) = 15 * e^{-15}[/tex]

So:

[tex]P(X\le 1) = e^{-15} + 15 * e^{-15}[/tex]

[tex]P(X\le 1) = 0.00000489443[/tex]

[tex]P(X\le 1) = 0.0000049[/tex]

Answer:

The answer to number 6: 230.4(the unit measurement "cm" "mm" etc)

The answer to number 7: 140.673538 rad

Step-by-step explanation:

For number 6: To find area, it is length times width times height. In this case, the length is 7.2. The width is 8. The height is 4.

So length (7.2) times width (8) times height (4).

7.2 times 8 is 57.6

57.6 times 4 is 230.4

For number 7: To find the area it is length times width times height. In this case, the length is 62°. The width is 13. The height is 10.

So length (62°) times width (13) times height (10).

62° times 13 is 14.0673538 rad

14.0673538 rad times 10 is 140.673538 rad
