Answer:
375
Step-by-step explanation:
m= d * v
d= 3
v= 5 * 5 * 5= 125
125 * 3 = 375
Answer: a) 0.159, b) 0.366, c) 0.038.
Step-by-step explanation:
Since we have given that
Number of singles = 105
number of doubles = 2
Number of triples = 8
Number of home runs = 25
Number of strikeouts = 147
Number of walks = 95
Total number of times = 662
So, probability of him hitting a single when he comes to bat would be
Probability of getting he strikes out or walks when he comes to bat would be
Probability that it is a home run is given by
Hence, a) 0.159, b) 0.366, c) 0.038.
Answer:
56 + 53pi
Step-by-step explanation:
<u><em>Area of small circles:</em></u>
diameter of small circle: 4cm
forumla to find area of circle: A = pir^2
r is radius = half of diameter -> d/2 = 4 / 2 = 2cm
A = pi (2cm)^2
A = pi (4cm)
A = 4pi
<u><em>Area of large circle:</em></u>
diameter of small circle: 4cm
forumla to find area of circle: A = pir^2
r is radius = half of diameter -> d/2 = 14 / 2 = 7cm
A = pi (7cm)^2
A = pi (49cm)
A = 49pi
<u><em>Area of rectangle:</em></u>
Area = width x length
Area = 14cm x 4cm
Area = 56cm
<u><em>Add all three areas:</em></u>
Area of rectangle + large circle + small circle
56cm + 49pi + 4pi = 56cm + 53pi
So if the "i" becomes confusing, just think of it as x
so it would become (-12+48x) +(15+21x)
then you would split up the terms by constants and coefficients
-12+15 +48x+21x
3+69x and then you substitute back for i
3+69i
Answer:
0.68268
Step-by-step explanation:
We solve using z score
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
For x = 85
z = 85 - 105/20
z = -1
Probability value from Z-Table:
P(x = 85) = 0.15866
For x = 125
z = 125 - 105/20
z = 1
Probabilty value from Z-Table:
P(x = 125) = 0.84134
The probability that a randomly selected adult has an IQ between 85 and 125 is calculated as:
P(x = 125) - P(x = 85)
= 0.84134 - 0.15866
= 0.68268
