There are 15 pens and 10 pencils in a box. One object is selected at random and then replaced. Another is the selected. Find the probability that:

1. The first object selected is a pen and the second is a pencil
2. One is a pen and the other is a pencil
3. Both are pencils
4. At least one is a pen

Four questions in total

Answers

Answer 1

Step-by-step explanation:

1. P(pen then pencil) = 15/25 × 10/25 = 3/5 × 2/5 = 6/25

2. P(pen then pencil) + P(pencil then pen) = 6/25 + 6/25 = 12/25

3. P(pencil then pencil) = 10/25 × 10/25 = 2/5 × 2/5 = 4/25

4. P(at least 1 pen) = 1 − P(no pen) = 1 − 4/25 = 21/25

Polygons are 2 dimensional shapes with straight edges (no curved edges). The shape needs to be closed up entirely to be a polygon. It cannot have any intersecting line segments

A can't be a polygon because the shape isn't closed up entirely

C can't be a polygon because it is a 3d shape

D can't be a polygon because it has curved edges.

H can't be a polygon because it isn't closed up (there are no line segments).

Write the equation g(x) of the transformation of the parent graph f(x) = |x| reflected over the x axis.

Answers

Answer:

g(x) = -|x|

Step-by-step explanation:

f(x) = |x|

y = −f(x)  Reflects it about x-axis

g(x) = -|x|

We start off with: f(x) = |x|

Reflection across x-axis

y = -f(x)

After: g(x) = -|x|

ANSWER THIS QUESTION WITH WORKING PLEASE :>!!!

Answers

Step-by-step explanation:

y + 65°= 180° (Being co-interior angle)

y = 180° - 65°

y = 115°

Next we will find of the next co-interior angle which is A and D

(2x - 10)° + (3x + 20)° = 180° ( Same reason)

Now we will keep the like ones together.

2x° + 3x° - 10° + 20° = 180°

5x° + 10° = 180°

5x = 180° - 10°

5x = 170°

x = 170°/5

x = 34°

Now we need to find (2x - 10)° and (3x + 20)°

(2x - 10)°

=(2×34-10)°

=(68-10)°

=58°

(3x + 20)°

=(3×34-20)°

=(102-10)°

=92°

Find the perimeter of the polygon with the given vertices Round your answer to the nearest hundredth ​

Answers

Answer:

16.93 units

Step-by-step explanation:

Length of a segment having extreme ends [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

ML = [tex]\sqrt{(4-1)^2+(0-4)^2}[/tex]

     = 5 units

LP = [tex]\sqrt{(1+1)^2+(4+2)^2}[/tex]

    = [tex]\sqrt{40}[/tex] ≈ 6.32 units

PN = [tex]\sqrt{(-1-2)^2+(-2-0)^2}[/tex]

     = [tex]\sqrt{13}[/tex]

     ≈ 3.61 units

NM = [tex]\sqrt{(4-2)^2+(0)^2}[/tex]

      = 2 units

Perimeter of the polygon MLPN = ML + LP + PN + NM

                                                     = 5 + 6.32 + 3.61 + 2

Step-by-step explanation:

Speed = distance/time

Given parameters

Distance = 3/10 miles

Time = 10miuntes

Convert the time to hours

10minutes = (10/60)hour

10minutes = 1/6 hour

Substitute the parameters into the formula;

Distance = (3/10)/(1/6)

Distance = 3/10× 6/1

Distance = 18/10

what is 4.5x10^-6 in standard notation?

Answers

It would be 0.0000045 because it is a - you go left but if it was positive you would go right and you are moving the decimal

The number 4.5x10⁻⁶ can be expressed in standard notation as decimal 0.0000045.

In scientific notation, numbers are expressed as a decimal number between 1 and 10 multiplied by a power of 10. In this case, 4.5 is the decimal number and 10⁻⁶ represents the power of 10.

To convert this to standard notation, we move the decimal point six places to the left to match the negative exponent of 10⁻⁶. This gives us:

0.0000045

In standard notation, this number is written as 0.0000045, where the zeros after the decimal point indicate the value of the number in the place of each digit. The last non-zero digit in this case is 5, which is in the sixth decimal place.
