Answer:
the answer would be B I believe
3/4*1/4= 3/16 or 0.1875 (you times 3 by 1 and 4 by 4)
3/4*8= 6
first bracket = 3/16+ 6
1/2+2= 2 1/2 or 2.5
second bracket = -2.5
-3/8*4= -1.5
-3/8*x= -3/8x or -0.375x
third bracket= -0.375x
so
(0.1875+6) - (2.5) - (0.375x) - (0.25x)
collect like terms
6.2 - 2.5 = 3.7
0.375x - 0.25x = 0.125x
3.7-0.125x is your answer in decimal form
(3/16+6/1) - (2 1/2) - (3/8x-1/4x)
(6 3/16 - 2 1/2 )
(3 11/16)
3/8x-1/4x= 1/8x
final answer = 3 11/16 - 1/8x

Answer:
-3, 7
Step-by-step explanation:
EG = 5, so the distance between E and G is five.
G can be 5 units to the right of E:
2 + 5 = 7
G has coordinate 7.
G can be 5 units to the left of E:
2 - 5 = -3
G has coordinate -3.
Answer: -3, 7
Answer:
3972.72 specimens
Step-by-step explanation:
We solve using the z score formula:
z = (x-μ)/σ where
x is the raw score = 73 cm
μ is the population mean = 147 cm
σ is the population standard deviation = 30 cm
N is the number of samples = 4000
For x > 73
z = 73 - 147/30
z = -2.46667
Probability value from Z-Table:
P(x<73) = 0.0068189
P(x>73) = 1 - P(x<73) = 0.99318
The probability of having a height greater than 73cm is: 0.99318
The number of specimens that have a height greater than 73cm is calculated as: 0.99318 × 4000
= 3972.72 specimens
