Answer:
A] Probability = 1/n ; B] Number = 8
Step-by-step explanation:
Total counters = n , Blue counter = 1 , Red counters (remaining) = n -1
A] Prob (One blue, & One red counter) = (Blue counter / Total counters) x (Red counters / Total remaining counters) = [1 / n] x [ (n -1) / (n-1)] = 1 / n
Alternative, Prob (One red, & one blue) = (Red counter / Total counters) x (Blue counters / remaining counters) = [ (n-1) / n ] x [1 / (n-1) ] = 1 / n
B] Prob (each color , a blue & red counter taken) = 0.125 {Given}
By A], this Prob = 1/n.
So, 0.125 = 1/n → n = 1 / 0.125 = 8

A cylinder made of lead has a height of 4 inches and a diameter of 2 inches. How heavy is the cylinder if lead weighs 0.4 pound per cubic inch? Round to the nearest tenth.
Answer:5.0
Step-by-step explanation:
The volume of a cylinder is [tex]\pi r^2h[/tex], since the radius is 1/2D, 2/2=1. Now, if [tex]\pi[/tex] is rounded to 3.14, the volume of the cylinder would be 1 x 1 x 3.14 x 4 = 12.56. Now, since there are 0.4 pound per cubic inch, 12.56 x 0.4 = 5.024. Rounded to tenth, the answer is 5.0 or 5.
Hope this helps!
Why is the length of the base of the rectangle the same as the circumference of the circles in the net of a cylinder?

What is m
A: 19°
B: 68°
C: 112°
Answer:
m<N=68
Step-by-step explanation:
opposite angles of the parallelogram are equal(or congruent):
4x+36=6x-2
6x-4x=36+2
2x=38
x=38/2=19
the sum of the angles of the parallelogram =360
4x+36=4(19)+36=112 angle P
6x-2=6(19)-2=112 angle M
let Q= N=x
2x+112+112=360
2x=360-224
2x=136
x=136/2=68
Write the quadratic in standard form (x-8)^2 and please explain how you got it if u can cuz im trying to learn .
Answer:

Step-by-step explanation:
[tex](x-8)^{2}[/tex] is the same as saying [tex](x-8)(x-8)[/tex]
therefore, you use FOIL(first outside inside last) to get

THINK ABOUT WHETHER THEY ARE ASKING FOR CURCUMFERENCE OR AREA If you want to Make sure to have the most pizza which would you rather two 12 inch medium or one 18 inch large. Justify your answer mathematically
Answer:
The maximum pizza quantity would be with the pizza of 18 inch
Step-by-step explanation:
The size of the pizza in inches depicts its diameter.
Thus, 12 inch pizza means diameter of the pizza = 12 inch and 18 inch pizza means diameter = 18 inch
In case of either the CURCUMFERENCE OR AREA, the pizza with larger diameter will have larger CURCUMFERENCE and AREA as compared to the pizza with smaller diameter.
For instance
Area of 18 inch pizza
[tex]\pi * (18/2)^2\\= 254.34[/tex]Square inch
Area of 12 inch pizza
[tex]\pi * (12/2)^2\\= 113.04[/tex]Square inch
Circumference of 18 inch pizza
[tex]2*3.14*9 = 56.52[/tex]
Circumference of 12 inch pizza
[tex]2*3.14*6 = 37.68[/tex]

A car travels for 2 hours 15
minutes at an average speed
of 64 mph. Calculate the
distance travelled.
Answer:
231.746 km
Step-by-step explanation:
Formula: [tex]distance = speed[/tex] × [tex]time[/tex]
Solution: To solve for distance use the formula for distance
Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.
Firstly, convert the time from hours to minutes
2 hr 15 min = 2.25 hr
or 2.25 hr = 135 min
Now, use the formula:
135 × 64 = 8640
In km, the distance traveled is 231.74
What is the volume of the square pyramid? 11cm and 11cm
Answer:
1331 feet3
Step-by-step explanation:
Answer:
V = (1/3)(121 in^2)(11 in) = 443.7 in^3
Step-by-step explanation:
If the side length of the square base is 11 cm, then the area of that base is (11 cm)^2, or 121 cm^2. If the height of the pyramid is 11 cm (as you seem to indicate), then the volume of the squre pyramid is
V = (1/3)(121 in^2)(11 in) = 443.7 in^3
A motorcycle can go 50 miles on 1 gallon of gas. How many gallons will be used to go 150 km? I mile is about 1.6 km. Round to the nearest gallon.
Answer:
1.875 gallons
Step-by-step explanation:
Data
distance = 50 mi
volume of gas = 1 gal
volume for 150 km = ?
Process
1.- Convert 50 mi into kilometers
1 mile ------------------- 1.6 km
x ------------------ 150 km
x = (150 x 1)/1.6
x = 93.75 mi
2.- Calculate the gallons wasted
1 gallon ----------------- 50 mi
x ---------------- 93.75 mi
x = (93.75 x 1)/50
x = 93.75/50
x = 1.875 gallons

Subtract (5u + 6v) from (8u + 10v)
Answer:
-3u-4v
Step-by-step explanation:
5u+6v-(8u+10v)

=5u+6v+-1(8u)+-1(10v)
=5u+6v+-8u+-10v
(combine like terms)
=5u+6v+-8u+-10v
=(5u+-8u)+(6v+-10v)
=-3u-4v

The value of the subtraction will be equal to -3u-4v.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the two expressions are (5u + 6v) and (8u + 10v). The subtraction will be calculated as,
5u+6v-(8u+10v)
S =5u+6v+-1(8u+10v)
S =5u+6v+-1(8u)+-1(10v)
S =5u+6v+-8u+-10v
(combine like terms)
S =5u+6v+-8u+-10v
S =(5u+-8u)+(6v+-10v)
S =-3u-4v
Therefore, the value of the subtraction will be equal to -3u-4v.

what is 9-x/5=3?
I kept getting 6 but the only option is -6 :/
Step-by-step explanation:
[tex]9 - \frac{x}{5} = 3 \\ 9 - 5 \times \frac{x}{5} = 3 \times 5 \\ 9 - x = 15 \\ - 9 - x = - 9 + 15 \\ - x = 6 \\ - x \div - 1 = 6 \div - 1 \\ x = - 6[/tex]
Answer:
Yeah the answer is -6
Step-by-step explanation:
9-x/ 5= 3
9-x = 15 (5 times three)
-x = 6 (9-6)
x= -6 ( a variable can never Be negative, but we have to give the minus to 6)

If one of the 50 states is chosen at random, then a dice is rolled. Find the probability of getting a state that starts with the letter A and a number less than 3. Pls, help me this is due by tomorrow at 8 am!
Note: 2/75 = 0.0267 = 2.67% approximately
========================================================
Explanation:
The states that start with "A" are:
AlabamaAlaskaArizonaArkansasWe have four states out of 50 total. The probability of picking a state that starts with "A" is 4/50 = 2/25.
When rolling a single die, the possible outcomes are {1,2,3,4,5,6}. The subset {1,2} represents any time we roll less than three. There are 2 ways to roll less than three, out of 6 ways total. So we have a probability of 2/6 = 1/3 here.
We'll multiply the fractions to get our answer:
(2/25)*(1/3) = (2*1)/(25*3) = 2/75
