Answer:
z= 2.38
P = 0.008656
Step-by-step explanation:
Here n= 500 and p~= 464/500= 0.928 and q`= 1- 0.928 = 0.072
We formulate our null and alternate hypothesis as
H0 = 0.9 ; H0 > 0.9
The degree of confidence = 90%
z₀.₀₅ = 1.645 for α= 0.05
We use the test statistic
z= x- np/√npq
z= 466-500 *0.9/ √500 * 0.9(1-0.9)
z= 466- 450/ √45
z= 16/6.7082
z= 2.38
As the calculated value of z= 2.38 is greater than α =1.645 so we reject H0.
If H0 is true the P value is calculated as
P = 1- Ф( 2.38)
P = 1-0.991344=0.008656

Answer:
The formula of a Pythagorean Theorem is a^2 + b^2 = c^2
The length of c is 5 inches.
Step-by-step explanation:
a^2+b^2=c^2
3^2+4^2=c^2
25=c^2
Square root of 25= square root of c^2
5=c
Note that "^" means the number to the specified number.
Ex: 2^3
2 to the third power
or
2 cubed
Hope this helps!!!
Please consider this as brainliest thanks!!!
First you need to change the equation to 3 < x/2 + 1
then we can treat it like a normal equation.
subtract 1 from each side to get 2 < x/2
then multiply both sides by 2 to get rid of the fraction and we have
4 < x and we switch it around to get
x > 4 as our answer! :)
