Cylinder: 1²(3) = 3
3(9) =27
Prism: 4x3x6 =72
Total: 72+27 = 99in³
Answer:
3(x-2) (x+4)
Step-by-step explanation:
Factor the polynomial
73 lb 9 oz is 1177 oz
38 lb 14 oz is 622 oz
1177-622= 555
555/16
34 . 6875
.6875 of a lb is 11 oz
The final answer is 34 lb and 11 oz
Answer:
The number of students who scored more than 90 points is 750.
Step-by-step explanation:
Quartiles are statistical measures that the divide the data into four groups.
The first quartile (Q₁) indicates that 25% of the observation are less than or equal to Q₁.
The second quartile (Q₂) indicates that 50% of the observation are less than or equal to Q₂.
The third quartile (Q₃) indicates that 75% of the observation are less than or equal to Q₃.
It is provided that the first quartile is at 90 points.
That is, P (X ≤ 90) = 0.25.
The probability that a student scores more than 90 points is:
P (X > 90) = 1 - P (X ≤ 90)
= 1 - 0.25
= 0.75
The number of students who scored more than 90 points is: 1000 × 0.75 = 750.
Answer:
(2, - 2 )
Step-by-step explanation:
y = - 3 +
x → (1)
3x + 2y = 2 → (2)
Substitute y = - 3 +
x into (2)
3x + 2(- 3 +
x) = 2 ← distribute parenthesis and simplify left side
3x - 6 + x = 2
4x - 6 = 2 ( add 6 to both sides )
4x = 8 ( divide both sides by 4 )
x = 2
Substitute x = 2 into (1)
y = - 3 +
(2) = - 3 + 1 = - 2
solution is (2, - 2 )
