If Albert Enstein has 53 socks in his drawer: 21 identical blue, 15 identical black and 17 identical red. The lights are out and he is completely in the dark. How many socks must he take out to make 100 percent certain he has at least one pair of black socks?
Answers
Answer:
6 socks
Step-by-step explanation:
What we must do is calculate the probability of this happening, that he takes out two black socks in the first two taken out.
There are 12 black socks and in total they are 24, therefore the probability of drawing 1 is:
12/24
and now the probability of getting another one is 11 (there is one less outside) and in total they are 23:
11/23
the final probability is the multiplication of these events:
(12/24) * (11/23)
P = 0.24
Now, to know how many you should get, we multiply the probability by the total number of socks, that is:
0.24 * 24 = 5.76
So you must take out at least 6 socks for the above to happen.
the number of socks Albert Enstein has to take out to be sure that he has at least one pair of black socks is 38.
In order to determine the number of socks Albert Enstein has to take out to be sure that he has at least one pair of black socks, we would have to add the number of blue socks with the number of red socks.
Number of socks to be taken out = number of blue socks + number of red socks
21 + 17 = 38 socks

5 The smallest angle of a triangle, in degrees, is p.
The second angle is 4 times the smallest angle.
The third angle is 5 times the smallest angle.
a Write an equation for the angles in the triangle in terms of p.
b Find the size of the largest angle in the triangle.
b in paticular
Answers
Answer: b = 90
Step-by-step explanation:
Full triangle is 180
5 + 4 = 9 + 1 (the smallest angle)
180 ÷ 10 = 18
First and smallest angle is 18
p= 18
Second angle is 72
18 × 4 = 72
Thrid angle is 90
18 × 5 = 90
b = 90
18 + 72 = 90 + 90 = 180

A. 9w + 2
B. 3w + 12
C. 11w - 4
D. 11w + 4
Hint: It's not A, or B
Answers
Answer:
the answer is B
Step-by-step explanation:
6w + 5 - 3w + 7
i) collect like terms= 6w - 3w + 5 + 7
= 3w + 5 + 7
ii) add the numbers= 3 w + 5 + 7
= 3w + 12
6w+5-3w+7
6w - 3w = 3w
5 +7=12
this means 3w+12

Mr. Sonny's science class is calculating the average number of blinks per minute. Jan blinks 126 times in 7 minutes. What is her blinking rate, in blinks per minute?
Answers
b. Every 24 minutes
Step-by-step explanation:
A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes.
The first step is to:
Find and list multiples of each time each neon sign blinks.
This means, we find the Multiples of 6 and 8
Multiples of 6:
6, 12, 18, 24, 30, 36
Multiples of 8:
8, 16, 24, 32, 40
The first and common multiple of 6 and 8.
Therefore, the Least common multiple [LCM(6, 8) ] = 24
Hence, they often blink at the same time every 24 minutes.
Therefore, option b.Every 24 minutes is correct.

question:
1. Use the Pythagorean theorem to find AD.
2. Find AC. Show your work.
3. Is ΔABC a right triangle? Explain.
SHOW YOUR WORK
Answers
Problem 1
Answer: AD = 9
-------------------------------------------------
Work Shown:
Focus on triangle ADB, which is the smaller triangle on the left.
We have these side lengths
AD = unknown leg
BD = 12 = known leg
AB = 15 = known hypotenuse
Let's apply the Pythagorean Theorem to find the unknown leg
a^2 + b^2 = c^2
(AD)^2 + (BD)^2 = (AB)^2
(AD)^2 + (12)^2 = (15)^2
(AD)^2 + 144 = 225
(AD)^2 = 225-144
(AD)^2 = 81
AD = sqrt(81)
AD = 9
Side AD is 9 units long.
========================================================
Problem 2
Answer: AC = 25
-------------------------------------------------
Work Shown:
AC = AD + DC .... segment addition postulate
AC = 9 + 16 ..... substitution; refer to problem 1
AC = 25
========================================================
Problem 3
Answer: Triangle ABC is a right triangle.
-------------------------------------------------
Work Shown:
The Pythagorean Theorem Converse says "if a^2+b^2 = c^2 is a true equation, then the triangle with sides a,b,c is a right triangle". Keep in mind that c is always the longest side (hypotenuse). The order of 'a' and b doesn't matter. Convention has us usually do [tex]a \le b[/tex] but again the order isn't important.
We have these three sides
a = 15 (length of side AB; leg #1)b = 20 (length of BC; leg #2)c = 25 (length of AC; hypotenuse)Plug those values into the equation below. Simplify each side.
a^2+b^2 = c^2
15^2 + 20^2 = 25^2
225 + 400 = 625
625 = 625
We get a true equation. Therefore, triangle ABC is a right triangle.
Answer:
Step-by-step explanation:
Pythagorean = c^2 =a^2 + b^2
we are given c and a so solve for b
c^-a^2 = b^2
15^2- 12^ = b^2
81= b^2
[tex]\sqrt{81}[/tex]=b
9=b
AD=b
AC = AD + 16
AC =9 + 16 =25
if it's a right triangle then Pythagorean will work with the sides to make 25
AC^2 = 15^2+20^2
AC = [tex]\sqrt{625}[/tex]
AC = 25
