To find the mean add up all the numbers and divide. The mean absolute deviation is the difference.
Answer:7/8
A coin is tossed 3 times. The probability of getting at least one head is 7/8.
Answer:
C) 20, 4
Step-by-step explanation:
X = 5y
2x + 5y = 60
substitute in 5y for x: 2(5y) + 5y = 60
10y + 5y = 60
15y = 60
y = 4
x = 5y
x = 5(4) = 20
Answer:
ai. $240
aii. $120
bi. $840
bii. $70
c. 120 + 60(x) = A
d. [120 + 60(x)]/x = M
Step-by-step explanation:
Please kindly see the attached for detailed explanation
See the attached figure
DB = 4 and DC = 6 , We need to find AD
Using <span>Euclid's theorem for the right triangle
</span><span>
</span><span>∴ DB² = AD * DC
</span><span>
</span><span>∴ 4² = AD * 6
</span><span>
</span><span>∴ 6 AD = 16
</span><span>
</span><span>
</span><span>
∴ AD = 16/6 = 8/3 ≈ 2.67</span>
