Answer:
Kindly check explanation
Step-by-step explanation:
(a)
H0 : μ = 12
H1 : μ > 12
This is a right tailed test ; the alternative hypothesis has a greater than sign, difference between sample and population mean value will be positive.
(b)
H0 : μ = 10
H1 : μ > 10
This is a right tailed test ; the alternative hypothesis has a greater than sign, difference between sample and population mean value will be positive.
(c)
H0 : μ = 100
H1 : μ < 100
This is a left tailed test ; the alternative hypothesis has a less than sign, difference between sample and population mean value will be negative.
(d)
H0 : μ = 12
H1 : μ > 12
This is a right tailed test ; the alternative hypothesis has a greater than sign, difference between sample and population mean value will be positive.
Answer:
(m + 7)^2
Step-by-step explanation:
The SQUARE of (The SUM of m and 7)
Let us try (The SUM of m and 7) first
(m + 7)
then try the square
(m + 7)^2
Answer:
1. d) P = 3.86n
2. b) A = 85.50n
Step-by-step explanation:
Answer: The correct answer is C: 6x² + x - 26 = 0
Step-by-step explanation: All the variables in the question have been identified, that is, the area, the height and the base of the triangle. The area of a triangle is defined as
Area = ½ x B x H
Area = 13,
Base = B and
Height = 6B + 1
The question states that the height is 1 more than 6 times it's base. Hence the height would be, Base x 6, plus 1, that is, 6B + 1
The area can now be expressed properly as follows,
13 = ½ x B x (6B + 1)
By cross multiplication we now have
2 x 13 = B (6B + 1)
26 = 6B² + B
Subtract 26 from both sides of the equation
6B² + B - 26 = 0
However, the answer uses x as the unknown variable. So if you use x as the base of the triangle instead of B, your answer would result in
6x² + x - 26 = 0
