Total number of marbles = 4 + 7 + 6 = 17
Number of green marbles = 7
Probability of first marble being green = 7/17
Probability of the second marble being green = 6/16
Probability of the third marble being green = 5/15
Probability (3 green) = 7 / 17 * 6/16 * 5/15 = 210 / 4080 = 0.05147

Answer:
r = 6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
PR² = PQ² + QR² , substitute values
(r + 4)² = r² + 8²
r² + 8r + 16 = r² + 64 ( subtract r² from both sides )
8r + 16 = 64 ( subtract 16 from both sides )
8r = 48 ( divide both sides by 8 )
r = 6
What is the coefficient of x4 y3 term in the expansion of ( x-2y )7?
The coefficient of x⁴y³ term in the expansion of (x - 2y)⁷ is 280.
What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.
Given expression:
(x - 2y)⁷
Expand this as given below,
(x - 2y)³ × [(x - 2y)²]²
(x³ + 6x²y + 12xy² + 8y³) × [(x² + 4y² - 4xy)]²
Solve the above expression to get,
x⁷ + 14x⁶ + 84x⁵y² + 280x⁴y³ + 560x³y⁴ + 672x²y⁵ + 448xy⁶ + 128y⁷
Here, the coefficient of the x⁴y³ is 280,
Therefore, the coefficient of x⁴y³ term in the expansion of (x - 2y)⁷ is 280.

Answer:
aₙ=5*4ⁿ⁻¹
Step-by-step explanation:
The common ratio is r=80/20=20/5=4
The explicit formula for a geometric sequence is aₙ=a₁*rⁿ⁻¹ where aₙ is the nth term, r is the common ratio, and a₁ is the first term.
Given:
a₁=5
r=4
Therefore, the explicit formula for the sequence is aₙ=5*4ⁿ⁻¹

Find the length of each bolded ARC round to the nearest hundredth 5 mm and 232 Help ASAP
9514 1404 393
Answer:
20.25 mm
Step-by-step explanation:
Arc length is given by the relation ...
s = rθ
where r is the radius and θ is the central angle in radians.
There are π radians in 180°, so the arc length is ...
s = (5 mm)(232°×π/180°) = 20.25 mm
The arc length is about 20.25 mm.
To make his house more energy-efficient, Ernest is putting solar film on the large trapezoid-shaped window in his living room. The window has an area of 25 square feet. The top of the window is 3 feet long, and the bottom is 7 feet long. Which equation can you use to find how tall the window is, h? 25=h(3+7) 25= 1 2 h(3+7) How tall is the window? Write your answer as a whole number or decimal. Do not round.
Answer:
25 = 1/2(3 + 7)h
5 feets
Step-by-step explanation:
Given that:
Window shaped in the form of a trapezium :
The length of its bases :
Top of window base = 3 feets
Bottom of window base = 7 feets long
Area of Windom = 25 feets²
Recall :
Area of a trapezium is given by :
Area, A = 1/2(a + b)h
a and b are the bases
h = height
Inputting the Given values into the equation :
25 = 1/2(3 + 7)h
Hence, the height of the window can be Obtian using the expression
25 = 1/2(3 + 7)h
25 = 1/2(10)h
25 = 5h
h = 25 /5
h = 5 feets

is it true or false?? i will mark brainlest the correct answer
Answer:
True
Step-by-step explanation:
In order to calculate this, we simply need to replace the variable c with the value of -8 and solve the inequality.
-9c >= 63
-9 * -8 >= 63
72 >= 63
Since both values are negative the product will be positive. This product is 72 which is in fact greater than 63, thus making the statement True

To the nearest degree, what is m A
Answer:
53°
Step-by-step explanation:
With reference angle A
perpendicular (p) = 9.6
base (b) = 7.2
Now
tan A = p / b
tan A = 9.6 / 7.2
A = tan^ - 1 ( 9.6 / 7.2)
A = 53°
