Answer:
4.78 pounds
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 9.2 pound
σ is the population standard deviation = 3.4 pounds
z = 1.3
We are to find x
Hence,
-1.3 = x - 9.2/3.4
Cross Multiply
-1.3 × 3.4 = x - 9.2
-4.42 = x - 9.2
x = -4.42 + 9.2
x = 4.78 pounds.
Therefore the weight of the cat is 4.78 pounds
|x - 1| > 4 ⇔ x - 1 > 4 or x - 1 < -4 |add 1 to both sides
x > 5 or x < -3
Answer: c. {x| x < -3 or x > 5}.
Area of a triangle: (1/2)bh, where b = base and h = height
(1/2) x 4 x (11/2)
= (4/2) x (11/2)
= 2 x (11/2)
= 11
