Answer:
The value of the test statistic
Step-by-step explanation:
From the question we are told that
The high dropout rate is %
The sample size is
The number of dropouts
The probability of having a dropout in 1000 people
Now setting up Test Hypothesis
Null
Alternative
The Test statistics is mathematically represented as
substituting values

Answer:
24 1/7
Step-by-step explanation:
4x + 3x - 8 = 90
7x = 82
x = 10 5/7
(3x-8)
225/7 - 8
32 1/7 - 8
24 1/7
Answer:
F = 585844 N
Step-by-step explanation:
Given that:
A semicircular plate with radius 7 m is submerged vertically in water so that the top is 3 m above the surface.
The objective of this question is to express the hydrostatic force against one side of the plate as an integral and evaluate it.
To start with the equation of a circle: a² + b² = r²
The equation of circle with radius r = 7 can be expressed as:
a² + b² = 7²
a² + b² = 49
b² = 49 - a²
b =
NOW;
The integral of the hydrostatic force with a semicircular plate with radius 7 m and the top is 3 m above the surface can be calculated as follows:
where;
density of water is 1000 kg/m3
and acceleration due to gravity is 9.8 m/s
Solving the integral; we have:
F = 2 × 1000 kg/m³ × 9.8 m/s × (29.89)
F = 585844 N
