Birth control pills have a theoretical annual efficacy of 99.5%, but a real-worls efficacy of only 95%. If a college student takes the pill for the four years she is in college, what is the probability that she will become pregnant at least once using the theoretical efficacy rate?

A. 0

B. 0.005

C. 0.020

D. 0.185

Answer:

The first answer and the second answer.

Step-by-step explanation:

So when they say parrallel, they mean all the angles on one set of lines are exactly the same with the ones on the other lines.

Knowing this, we can easily see that:

angle 1 is equal to angle 3

angle 2 is equal to angle 4

angle 5 is equal to angle 7

angle 6 is equal to angle 8

So looking at the answers it must me:

A

B

Hope this helps! ;)

I attached a file if you want to have a visual understanding of this problem as well.

Answer:

D

Step-by-step explanation:

-3/8 converted to a decimal is -0.375

The absolute value of -0.5 is 0.5

hence, 0.5 is larger than -0.375

so the answer is d

Answer:

The loss is $120 and the loss percentage is 8%.

Step-by-step explanation:

Given that,

SP of a car = $1,380

CP of a car = $1,500

As CP > SP, it means there is a loss in selling of that car.

Loss = CP - SP

= $1,500 - $1,380

= $120

Loss percentage,

[tex]\%=\dfrac{loss}{CP}\times 100\\\\=\dfrac{120}{1500}\times 100\\\\=8\%[/tex]

Hence, the loss is $120 and the loss percentage is 8%.

The slope of the line represented by the equation y= -2/3 - 5x is -5.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have,

y= -2/3 - 5x

We know from slope intercept form

y= mx + b

Where m is the slope and b is the y intercept.

Now, Comparing with given equation we get

m = -5 and b= -2/3

Thus, the slope of line is -5.

Hello Love! This is A Triangular Prism

Hope that helps!

Answer: Triangular Prism

Step-by-step explanation:

There’s no way to explain this, but you can easily find the answer by searching “what does a rectangular prism look like” and go through each of the answer choices until you find one that matches.

Answer:

the number of possible selection is 12650

Option b) 12650  is the correct answer.

Step-by-step explanation:

Given the data in the question;

total number of students n = 25

number of student selected r = 4

[tex]^nC_r[/tex] = ²⁵C₄

= 25! / ( 4!( 25 - 4 )! )

= 25! / (4!(21)!)

=  12650

Therefore, the number of possible selection is 12650

Option b) 12650  is the correct answer.

Answer:

x = 193

Step-by-step explanation:

distribute 13 into (x - 15)

=> 12x - 2 = 13x - 195

subtract 12x on both side

=> -2 = x - 195

add 195 on both side

=> x = 193

A. Make an overestimate and an underestimate of the total quantity of pollutants that escape during the first month.

Overestimate

For this case, we review the data in the table. The value for first month of total quantity of pollutants that escape is 7. Additionally, we can notice that the rate is increasing.

Just a month and that month has a value of  7

= 1* 7 (The largest value) = 7

Underestimate

This would be equivalent to the total until the previous meassure

Step-by-step explanation:

The perimeter of the polygon is the sum of the lengths of its sides. Opposite sides in this geometry have the same sum, so the perimeter is ...

  P = 2(16.4 +19.3) = 2(35.7)

  P = 71.4 . . . units

The equation to represent the relationship between red paint, r, and yellow paint, y, in each batch can be written as r = 3 / 2y.

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given:

At r = 2, y = 3,

r = 4, y = 6,

r = 6, y = 9

Here, r is red paint and y is yellow paint.

The above condition can be written as

2r = 3y

r = 3 / 2y

Therefore, the equation to represent the relationship between red paint, r, and yellow paint, y, in each batch can be written as r = 3 / 2y.
