Answer:
The middle term of the product of (x - 4)(x - 3) is -7
Step-by-step explanation:
Consider the given expression (x - 4)(x - 3)
We have to find the middle term of the product of (x - 4)(x - 3).
First multiply the given terms, we get,
Simplify, we get,
Simplify further, we get,
Thus, the middle term of the product of (x - 4)(x - 3) is -7

Answer:
a) 14√5 feet
b) about 31.3 feet
Step-by-step explanation:
a) The 42-ft hose is the hypotenuse of a right triangle with one leg 28 ft. We are asked to find the other leg. The Pythagorean theorem is useful.
h² +(28 ft)² = (42 ft)²
h² = (1764 -784) ft² = 980 ft²
h = √(196·5) ft
h = 14√5 ft
__
b) The approximate height is ...
14√5 ≈ 31.305, about 31.3 feet
Answer:
(a)0.3303
(b)0.6697
Step-by-step explanation:
Point estimation is the use of sample data to calculate a single value which serves as a best estimate of a given unknown population parameter.
Total Sample=1226
Number who said that they were not confident that the food they eat in country A is safe=405.
The point estimate of those who said that they were not confident that the food they eat in country A is safe is given as
(a)Point Estimate for p,
(b)Point estimate for q, 1- (point estimate for p)
=1-0.3303
=0.6697
