Answer:
6.67 yards is 20 feet. 8 yards is 24 feet. Not quite sure of the question
Step-by-step explanation:
Answer:
<u>There are:</u>
- 6 red balls - R
- 5 black balls - B
- Total number = 11 balls
<h3>A. Without replacement</h3>
i. <u>Two blacks </u>
ii. <u>The first is black</u>
or, alternatively
- P(BR or BB) = 5/11*6/10 + 2/11 = 3/11 + 2/11 = 5/11
iii. <u>Both are of same colour</u>
- P(BB or RR) = 2/11 + 6/11*5/10 = 2/11 + 3/11 = 5/11
<h3>B. With replacement</h3>
i. <u>Two blacks </u>
- P(BB) = 5/11*5/11 = 25/121
ii. <u>The first is black</u>
or alternatively
- P(BR or BB) = 5/11*6/11 + 25/121 = 30/121 + 25/121 = 55/121 = 5/11
iii. <u>Both are of same colour</u>
- P(BB or RR) = 5/11*5/11 + 6/11*6/11 = 25/121 + 36/121 = 61/121
Answer:
JM ≈ 12.9 miles
Step-by-step explanation:
The length of the arc is calculated as
arc = circumference × fraction of circle
= πd × 
JM = π × 16.4 × 
=
≈ 12.9
Answer:
HL
Step-by-step explanation:
Since we have two pairs of congruent sides with the included angle, one pair of which are the hypotenuses, then the triangles are congruent by HL.
Answer:bh
345
Step-by-step explanation:
y is in direct proportion to x. x = 25, y = 5. Find the value of y, if x = 9.
