Answer:
C 974,000
Step-by-step explanation:
7.4 × 10^4 + 9.0 × 10^5 =
= 0.74 × 10^5 + 9.0 × 10^5
= 9.74 × 10^5
= 974,000
Answer:
walkway
around the garden as the sum of two terms
Step-by-step explanation:
A rectangular garden has a walkway around it. The area of
The garden is 6(6.5x+3.5). The combined area of the garden
And the walkway is 6.5(8x+5). Find the area of the walkway
around the garden as the sum of two
Answer:
42,44,46
Step-by-step explanation:
we first divide the 132 by the 3 which gives 44
since the numbers involved are even numbers and we know even numbers are numbers divisible by 2 we subtract 2 from the 44 and also add 2 to the 44 the get the rest of the two numbers which is from the above explanation
(44-2),44,(44+2)
42,44,46
we can check whether the above numbers are correct by adding to see whether we get 132
42+44+46=132 which are consecutive even numbers
X=4
26x - 4 = 100
+4 +4
26x = 104
x = 104/26
x=4
Answer:
a) P( 
| X ) = 0.180
b) P(Y | 
) = 0.998
Step-by-step explanation:
Let
P(X) - Probability that he acts hungry
P(Y) - Probability that he had ate dinner,
Given,
P(X | Y) = 0.5
P(X | ) = 0.99
P(Y) = 0.9
a.)
P( | X ) = 
= 
= 0.180
⇒P( | X ) = 0.180
b.)
P(Y | ) = 
= ![\frac{(1 - 0.5)(0.9)}{1 - [(0.99)(0.1) + (0.5)(0.9) ]} = \frac{(0.5)(0.9)}{1 - [(0.099) + (0.45) ]} = \frac{0.45}{1 - [0.540]} = \frac{0.45}{0.451}](https://tex.z-dn.net/?f=%5Cfrac%7B%281%20-%200.5%29%280.9%29%7D%7B1%20-%20%5B%280.99%29%280.1%29%20%2B%20%280.5%29%280.9%29%20%5D%7D%20%3D%20%5Cfrac%7B%280.5%29%280.9%29%7D%7B1%20-%20%5B%280.099%29%20%2B%20%280.45%29%20%5D%7D%20%3D%20%5Cfrac%7B0.45%7D%7B1%20-%20%5B0.540%5D%7D%20%3D%20%5Cfrac%7B0.45%7D%7B0.451%7D)
= 0.998
⇒P(Y | ) = 0.998
