The probability that Romina randomly selects an oatmeal cookie from the bag, eats it, then randomly selects a sugar cookie is 7/100.

Probability determines the odds that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0. The more likely the event is to happen, the closer the probability value would be to 1.

The probability of picking an oatmeal cookie then a sugar cookie = (number of oatmeal cookies / total number of cookies) x (number of sugar cookies / total number of cookies -1)

Total number of cookies = 8 + 4 + 6 + 7 = 25

The probability of picking an oatmeal cookie then a sugar cookie = (7/25) x (6/24) = 7/100

The measure of ∠YZW is given as 180 degrees.

In the field of geometry, and in mathematics, the straight angle is one that is said to be equal to 180 degrees. That is, it is the angle that is called so based on the fact that it appears on a straight line. The sides of the angle are on separate positions compared to that of the vertex that appears also in a straight line.

Based on this explanation, we can see that ∠YZW appears on a straight line in the image that we have here.

Hence we would conclude by saying that The measure of ∠YZW is given as 180 degrees.

If  a package contains 12 resistors, 3 of which are defective. If 4 are selected, the probability of getting

a) 0 defective resistors: 0.3164

b) 1 defective resistor: 0.4219

c) 3 defective resistor: 0.0469

First step is to calculate the probability for a defective resistor and non-defective resistor:

Probability=3/12

Probability =0.25

Non-defective resistor:

Probability=(1-0.25)

Probability=0.75

Now  let find the probabilities for defective resistors from 0 to 3

P(0)=1(0.75)^4 ×(0.25)^0

P(0)=0.3164

P(1)=4(0.75)^3× (0.25)^1

P(1)=0.4219

P(2)=6(0.75)^2× (0.25)^2

P(2)=0.2109

P(3)=4(0.75)^0×(0.25)^3

P(3)=0.0469

P(4)=1(0.75)^0 × (0.25)^4

P(4)=0.0039

Hence,

a. P(0)=0.3164

b. P(1)=0.4219

c. P(3)=0.0469

Therefore If  a package contains 12 resistors, 3 of which are defective. If 4 are selected, the probability of getting 0 defective resistors: 0.3164, 1 defective resistor: 0.4219, 3 defective resistor: 0.0469.

The dimension of the triangle are base = 18 ft , height = 14 ft .

It is given that height of a triangle is 4 ft less than the base x which can be represented as height = x - 4   ....(2)  and base = x

Putting above values in equation (1) , we get

   [tex]126=\frac{1}{2} \times(x-4)\times x\\252=x(x-4)\\252=x^2-4x\\x^2-4x-252=0[/tex]

On factorizing , we get

  [tex]x^2-(18x-14x)-252=0\\(x^2-18x)+(14x-252)=0\\x(x-18)+14(x-18)=0\\(x+14)(x-18)=0[/tex]

On equating it with zero , we get

  [tex]x+14=0\\x=-14[/tex]

as length cannot be in negative so , we will not consider this solution.

The lowest percentage increase in the cost of dye that would make the scarves unprofitable is 42%

(Price- Unit Cost)/Price= 20% or 0.2

Price- Unit Cost= 0.2 Price

0.8 Price = Unit Cost

Let Unit Cost be x

Price = x/0.8= 1.25x

Dye is 60% of unit costs= 0.6x

Cost of remaining material= 1 - 0.6x = 0.4x

Unit Cost= Cost of Dye+ Cost of remaining material

So, in order to become unprofitable, Unit Cost must be 1.25x

Therefore

1.25x= Maximum cost of dye+ 0.4x

Maximum Cost of Dye = (1.25-0.4)x = 0.85x

Percentage change in cost of dye= {(0.85x-0.6x)/0.6x}*100= 41.66 or 42%

The answers are :

1. The equation of line parallel to y =  [tex]\frac{2}{5}[/tex] x - 3 will be y =  [tex]\frac{2}{5}[/tex] x - [tex]\frac{7}{5}[/tex] .

What is the slope intercept form of a line ?

The equation of line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.

1.

It is given that equation is : y = 2/5x - 3.

So , the slope here is 2/5 and a parallel line will have the same slope.

We know that the slope intercept form of a line is :

y = mx + c

Put , slope(m) = 2/5 in above equation.

Given , (1,-1) i.e., x = 1 and y = -1

Now we substitute these values to find value of c.

-1 = 2/5(1) + c

-1 = 2/5 + c

-1 - 2/5 = c

(-5 - 2)/5 = c

-7/5 = c

Putting m = 2/5 and c = -7/5 , we get :

So, the equation of parallel line is :

y =  [tex]\frac{2}{5}[/tex] x - [tex]\frac{7}{5}[/tex]

2.

We know that the product of the slope of two perpendicular lines is -1.

Given that equation is : y = -2/5x - 4 i.e., slope = -2/5

So , slope of a line perpendicular to this line is -1/(-2/5) = 5/2

And this line passes through the point (-3,1).

Equation of a line that passes through a point (x1 , y1) and slope (m) is :

(y-y1) = m (x-x1)

Here ;

x1 = -3 , y1 = 1 and m = 5/2

So , the equation of perpendicular line will be :

(y - 1) = [tex]\frac{5}{2}[/tex] (x - (-3))

(y - 1) =  [tex]\frac{5}{2}[/tex] (x + 3)

y - 1 =  [tex]\frac{5}{2}[/tex] x + [tex]\frac{15}{2}[/tex]

y =  [tex]\frac{5}{2}[/tex] x + [tex]\frac{15}{2}[/tex] + 1

y =  [tex]\frac{5}{2}[/tex] x + [tex]\frac{13}{2}[/tex]

Therefore , the answers are :

1. The equation of line parallel to y =  [tex]\frac{2}{5}[/tex] x - 3 will be y =  [tex]\frac{2}{5}[/tex] x - [tex]\frac{7}{5}[/tex] .

2. The equation of line perpendicular to y = - [tex]\frac{2}{5}[/tex] x - 4 will be y =  [tex]\frac{5}{2}[/tex] x + [tex]\frac{13}{2}[/tex] .

Step-by-step explanation:

The domain and range of the given graph is [tex][-3,-2) \sqcup (-1,5][/tex] and [tex][-5,4)[/tex] respectively .

From the graph , we can see that the left most point is when x = -3 and this point is closed in endpoint, so we will include this value of x in the domain.

Whereas its another point is on x = -2 which is not filled up so , we will not consider this value of x in the domain. In the interval , domain can be represented by [tex]-3\leq x < -2[/tex]  .This interval can be written as [tex][-3,-2)[/tex]

Now , the right most point is when x = 5 which is filled up so we will include this value of x in the domain. Whereas it's another endpoint is at x = - 1 , we will not consider this value of x in the domain as it is not filled up. In the interval , domain can be represented by [tex]-1 < x\leq 5[/tex] .This interval can be written as [tex](-1,5][/tex] .

In order to get the full domain of the function we will use union symbol

 [tex][-3,-2) \sqcup (-1,5][/tex]

For the range , we will observe the values of y . The lowest point is when y = -5 which is filled up so we will include this value of y in the range.

Whereas the highest point is when y = 4 which is not filled up so , we will not consider this value of y in the range . In the interval , range can be represented by [tex]-5\leq y < 4[/tex] .Since there are no gaps in the range, we don't use any union symbols here and hence range is [tex][-5,4)[/tex]

The temperature in degree Celsius when the temperature is 50°F is;  C = 10°C

We are given the formula for converting temperature from degree Celsius to degree Fahrenheit as;

F = ⁹/₅C + 32

Making C the subject;

⁹/₅C = F - 32

Multiply through by 5/9 to get;

C = ⁵/₉F - 32(5/9)

We are told that the temperature is 50°F. Thus;

C = ⁵/₉(50) - 32(5/9)

C = ⁵/₉ * 18
