What is the probability of randomly selecting a month pf year and not getting a month that ends in y?

Mathematics
1 answer:
Umnica [9.8K]2 years ago

Answer:

2/3

Step-by-step explanation:

The months whose names end in 'y' include Jan, Feb, May, Jul.  The probability of randomly selecting a month whose name ends in 'y' is 4/12 (remember that there are 12 months in a year), or 1/3.

Thus, the probability of selecting a month whose name does NOT end in 'y' is 8/12, or 2/3.  Note that this event is the 'complement' of the first event:  

P(name does not end in 'y') = 1 - P(name does not end in 'y') = 1 - 1/3 = 2/3

Could someone help?<br> Thank you
frozen [14]

Answer:

See Below

Step-by-step explanation:

Thankfully, all the parts you need are given.

First, find the surface of one triangle

A = 1/2bh

A = 1/2(15)(9)

A = 1/2(135)

A = 67.5

Multiply by 4 to get the sum of all the sides.

67.5(4) = 270

Now find the surface area of one square

A = bh

A = (15)(15)

A = 225

multiply by 5 to get all 5 sides

225(5) = 1125

Add sums together

1125 + 270 = 1395

What is (f+g)(x)? f(x)=x^2-36 g(x)=x^3+2x^2-10
docker41 [41]

Answer:

x³ + 3x² - 46

Step-by-step explanation:

note that (f + g)(x) = f(x) + g(x)

f(x) + g(x)

= x² - 36 + x³ + 2x² - 10 ← collect like terms

= x³ + 3x² - 46

How would you solve this? All I know is AD=24.4948
Mandarinka [93]

Answer:

8

Step-by-step explanation:

Let's call the center of the middle circle J, and the center of the third circle K.

Draw a line from J to the line AD such that the line is perpendicular to AD.

This forms a right triangle that is similar to the triangle ΔADK.

Writing and solving a proportion:

x / DK = AJ / AK

x / 5 = 15 / 25

x = 3

Now, draw lines from J to B and C.  We now form two congruent right triangles, where the hypotenuse is 5 and the shared leg is 3.

That means these are both 3-4-5 triangles.

Therefore, BC = 4 + 4 = 8.

Which line is perpendicular to a line that has a slope of 1/2?
Virty [35]

Answer:

LINE HJ

Step-by-step explanation:

The slop of the line you are given is 1/2. The perpendicular of that is -2/1. I got that bc it is the negative reciprocal.
