In a drawer there are 6 black socks,8 white socks,2 red socks, and 4 blue socks. A boy takes one socks from the drawer, without looking. What is the chance that this socks is blue?
Answer:
1/5
Step-by-step explanation:
Chance is also referred to as probability
probability = Number of event/Total samples space
If there are 6 black socks,8 white socks,2 red socks, and 4 blue socks in a drawer, the total number of socks will be the sample space
Sample space = 6 + 8 + 2 + 4
Sample space = 20socks
Total number of blue socks is the event
Number of event = 4 blue socks
Chance that the socks is blue = n(E)/n(S)
Chance that the socks is blue = 4/20
Chance that the socks is blue = 1/5

Kaitlyn buys books from a book club. She calculates the total cost, in
dollars, of each order using the formula 15b + 5. In her formula, b
represents the number of books she orders.
a) What is the total cost of ordering four books?
b) What is the total cost of ordering two books?
c) What is the total cost of ordering one book?
Answer:
c=what is the total cost of ordering one book..
Step-by-step explanation:
Given function:
15b+5What this means:
15b+5 means that 15+5..b=1 for 15+15so if the cost of the book is 15 dollars it adds 5 since you brought that book or for other reasons.15+5=1 book and b represents it.Therefore, b=the total cost of ordering one book..

A corporation reported cash of $26,200, total assets of $457,000, and total equity of $156,630 on its balance sheet. Its common-size percent for cash equals:
Answer:
Common-size percent for cash = 5.73 % (Approx.)
Step-by-step explanation:
Given:
Total cash = $26,200
Total assets = $457,000
Total equity = $156,630
Find:
Common-size percent for cash
Computation:
Common-size percent for cash = [Total cash/Total assets]100
Common-size percent for cash = [26,200/457,000]100
Common-size percent for cash = 5.73 % (Approx.)

A couch and coffee table cost a total of $1017 . The cost of the couch is two times the cost of the coffee table. Find the cost of each item.
Answer:
The couch costs $678 and $339 for the coffee.
Step-by-step explanation:
In total you spent $1017 and it was used in 3 portions, 2 for the couch, and 1 for the coffee. First divide it and find out how much each portion costs. In this case (1017 divided by 3) the answer will be 339. Now since you spent 2 of the 3 portions on the couch multiply one portion by 2. Then you get 678 for 2 portions, hence telling us that the couch costed, $678. With the remaining one portion of 339, you already know coffee costs $339.

Hope it is helpful....Find the discriminant of the quadratic equation and indicate the number of roots: (3x^2)+2x+1=0
Answer:
This expression has no roots.
Step-by-step explanation:
Using the discriminant: b² - 4ac, we get:
2² - 4 × 3 × 1
= 4 - 12
= -8
So this equation has no real solutions. Let's prove that by trying to solve for x:
3x² + 2x + 1 = 0
9x² + 6x + 3 = 0
9x² + 6x + 1 = -2
(3x + 1)² = -2
3x + 1 = i√2
3x = -1 ± i√2
x = (-1 ± i√2) / 3
The only solutions available then are indeed complex.
This expression has no roots. the discriminant of the equation is -8.
It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Using the discriminant: b² - 4ac, we get:
2² - 4 × 3 × 1
= 4 - 12
= -8
So this equation has no real solutions. Let's prove that by trying to solve for x:
3x² + 2x + 1 = 0
9x² + 6x + 3 = 0
9x² + 6x + 1 = -2
(3x + 1)² = -2
3x + 1 = i√2
3x = -1 ± i√2
x = (-1 ± i√2) / 3

(x2-25)÷(x-5) plz help me
Answer:
(x + 5)
Step-by-step explanation:
(x² - 25) ÷ (x-5)
=(x² - 5²) ÷ (x-5)
Using the formula a² - b² = (a + b)(a - b) you get
= (x + 5)(x - 5) ÷ (x - 5)
With division you can cut both (x - 5)
So the answer is (x + 5)

So the X has to be smaller than the Y. right?
ok, let's go with point M first shall we?
Coordinates are: 0, 6
is X smaller than Y? yes. yes indeed it is...

Point N:
Coordinates are: 3, 3
Is X smaller than Y? no. No they are not.

A helicopter hovers 500 feet above a small island. The figure shows that the angle of
depression from the helicopter
to point P is 49º. How far off
the coast, to the nearest foot, is the island?
Answer:
435 ft
Step-by-step explanation:
Reference angle = <P = 49° (angle of elevation)
Opposite side = 500 ft
Adjacent side = d = ?
Apply trigonometric function, TOA.
This:
Tan P = opp/adj
Tan 49 = 500/d
d × Tan 49 = 500
d = 500/Tan 49
d = 434.643369 ≈ 435 ft (to the nearest foot)
Is 3/2 greater than 1? Or Less than
Answer:
3/2 is greater than 1
Step-by-step explanation:
A little trick to immediately know if a number is more or less than when it involves fractions versus whole numbers is that improper fractions will always be greater than 1.
If you want to confirm this, dividing 3/2 equals 1.5, ergo 1.5 > 1.
In essence, improper fractions will always represent a number greater than one contrasted to proper fractions because if you put it on a perspective (let's say you have 13 pie slices but you only needed 12, that means there is a pie slice that's extra that makes it greater than the original pie slices).
