Answer:
0.07072
Step-by-step explanation:
Red Blocks= 31
Green Blocks= 47
Yellow blocks = 23
Purple blocks= 24
Total= 31+47+23+24= 125
P(Yellow) = 23/125
P(Purple)=24/125
NOTE: AND (X), OR (+)
P(yellow yellow or purple purple)
= P(Y and Y) + P(P and P)
=(23/125 X 23/125) + (24/125 X 24/125)
=529/15625 + 576/15625
=1105/15625
=221/3125
=0.07072
Therefore:
Probability of Picking Yellow Yellow or Purple Purple is 0.07072.

Answer:
x = -13
Step-by-step explanation:
9 - 2x = 35
<u>-9 -9 </u>
-2x = 26
divide by -2
x = -13
Step-by-step explanation:
x² + (y − 1)² = 9
This is a circle with center (0, 1) and radius 3. We can parameterize it using sine and cosine.
Use the starting point to determine which should be sine and which should be cosine.
Use the direction to determine the signs.
Use the number of revolutions and the interval to determine coefficient of t.
(A) Once around clockwise, starting at (3, 1). 0 ≤ t ≤ 2π.
The particle starts at (3, 1), which is 0 radians on a unit circle. It makes 1 revolution (2π radians). Therefore:
x = 3 cos t
y = 1 − 3 sin t
(B) Two times around counterclockwise, starting at (3, 1). 0 ≤ t ≤ 4π.
The particle starts at (3, 1), which is 0 radians on a unit circle. It makes 2 revolutions (4π radians). Therefore:
x = 3 cos t
y = 1 + 3 sin t
(C) Halfway around counterclockwise, starting at (0, 4). 0 ≤ t ≤ π.
The particle starts at (0, 4), which is π/2 radians on a unit circle. It makes 1/2 revolution (π radians). Therefore:
x = -3 sin t
y = 1 + 3 cos t
