Answer:
H0: u ≥ 9.5
Ha: u < 9.5
Step-by-step explanation:
The null hypothesis and the alternate hypothesis are reverse of each other.
The claim is either set as the null or alternate hypothesis
The null hypothesis is : H0: u ≥ 9.5 the mean breaking strength of a ceramic insulator is at least 9.5 which is considered equivalent to the standard.
The alternate hypothesis is: Ha: u < 9.5 the mean breaking strength of a ceramic insulator is less than 9.5 which is not considered equivalent to the standard.
since 2 sides will be 11 and the third side will be 8 the fourth side also needs to be 8 to make it a parallelogram
Answer:
3/10<10
Step-by-step explanation:
Answer:
57.14%
Step-by-step explanation:
So if he removes an orange ball from the bag, that means there are 8 white golf balls and 6 orange golf balls - 14 balls in total
8 balls of the 14 are white, so to find the percent we can set up a proportion
8/14=x/100
you can simplify 8/14 to 4/7
4/7=x/100
cross multiply
7x=400
divide by 7 on both sides
x=57.14%
3. With Inverse functions you just swap the x and the y values
