Hello
the answer is d
have a nice day
1) 85 is 20% of 425 (you can solve this by dividing 85 and 20%)
2) 22 is 11% of 200 (divide)
3) 60% of 145 is 87 (multiply 60% and 145)
4) he spent $33 (multiply)
5) B.25 (divide)
Answer:
(a) 8 balls
(b) 4 balls
Step-by-step explanation:
Let
Number of balls
For a box, the probability that there are N balls in it is:
For 2 boxes, it is:
From the question, we have:
Favorable outcome
To solve for N, we have:
Divide both sides by 2
Take log of both sides
Apply law of logarithm
Make N the subject
Approximate
Solving (b): Balls in one of the two boxes.
Here, we assume that each ball will have almost the same number of balls at a given instance;
Hence, we have:
<em>4 balls in each box</em>
Answer:
34.98yd^3
Step-by-step explanation:
Volume of a sphere V=4/3πr3
Where V = 2240yd^3
π = 3.14
2240 = 4/3×3.14×r^3
2240 = 4.1866r^3
r^3 = 2240/4.1866
r^3 = 534.784
r = ( 534.784 )^1/3
r = 8.1169
Since each dimension is to be multiplied by 1/4
Hence, 1/4×8.1169
r = 2.029.
New volume will be
V = 4/3×3.14×2.029^3
V = 4/3×3.14×8.3558
V = 34.98yd^3.
The range is a set of elements from the second set.
Therefore your answer is:
<h3>D. { -4, 1, 7, 15 }</h3>
