Step-by-step explanation: my assumption is that u r asking what 3% is. If u r then the answer above is correct bc 60 = 1% so multiply 60 by 3
If this is not what u r looking for please rephrase ur question
Answer:(c)
Step-by-step explanation:
Given : In a hypothesis testing the null hypothesis has been rejected when the alternative hypothesis has been true.
Find : to find that the given decision is create type I error , type II error or right decision has been taken
Step by step :
In hypothesis testing there are 2 types of error.
(1)Type I error :- if the null hypothesis is rejected when it is true, is known has Type I error .
(2)Type II error:- if the null hypothesis is accepted when alternative hypothesis is true, is known as type II error.
Since here null hypothesis has been rejected when alternative hypothesis has been true,i.e., the correct decision has been made
Hence option (c) is correct.
The two equations are
and
the first equation can be solved for x to be
next you can substitute x in the second equation
Distribute 4 to everything in the parentheses
combine like terms:
subtract 28 from both sides of the equation
divide both sides by -1.5
plug this in to the original equation of x+y=7
subtract 4 from both sides.
Final Answer: they bought 3 adult tickets and 4 student tickets
Hope this helps!
Let a ∈ A. Then a is some integer that is divisible by 4, so we can write a = 4k for some integer k.
We can simultaneously rewrite a as a = 2•2k, so 2 clearly divides a, which means a ∈ B as well.
Therefore A ⊆ B.
Answer:
In the first problem, the value of x is 13.85
Step-by-step explanation:
To find this, we can use the Pythagorean Theorem. This allows us to use the length of the legs (a and b) to determine the length of the hypotenuse (c) .
a^2 + b^2 = c^2
5.3^2 + 12.8^2 = c^2
28.09 + 163.84 = c^2
191.93 = c^2
13.85 = c
