Answer:
20 CDs
Step-by-step explanation:
36 x 42 = 1512
1532 - 1512 = 20
The last box has 20 CDs
Answer:
12 years
Step-by-step explanation:
every 4 years, olympic occurs.
Every 6 years, senator reelection.
if last year was 2020
in 2024 olympic will occur
in 2026 the reelection will occur
in 2028 olympic will occur
in 2032 olympic and reelection will occur will occur
2032 - 2020 = 12
12 years is the answer
I believe the selling price is 5 percent sorry if I’m wrong
Answer:
Decision rule is
Fail to reject the null hypothesis
The conclusion is
There is sufficient evidence that indicate that there is a significant difference between the two treatments
Step-by-step explanation:
From the question we are told that
The sample size is n = 12
The first mean is
The variance is
The second mean is
The second variance is
Let the level of significance be
The null hypothesis is
The alternative hypothesis is
Generally the test statistics is mathematically
=>
=>
Generally the degree of freedom is mathematically represented as
=>
Generally from the t- distriibution table the critical value of at a degree of freedom of is
Here given that the critical value is greater than the t statistics value the
Decision rule is
Fail to reject the null hypothesis
The conclusion is
There is sufficient evidence that indicate that there is a significant difference between the two treatments
Answer: 10 cosec (62°)
Step-by-step explanation:
The given triangle in the problem is a right triangle. This means that we can use SohCahToa to solve for the length of our hypotenuse (Line A to C).
** SohCahToa is a way for you to memorize special trigonometric functions that can be used:
Soh - Sin = Opposite / Hypotenuse
Cah - Cos = Adjacent / Hypotenuse
Toa - Tan = Opposite / Adjacent **
For this triangle, we can use the angle, 62°, to determine the hypotenuse. We will use x to represent the value between A and C. If you examine the sides of the triangle, you'll see that the side opposite of our angle is 10.
Because we have values that are located opposite to the angle and on the hypotenuse, we will use Sin(θ) = Opposite / Hypotenuse.
** θ represents your angle **
Sin(θ) = 10 / x
We want x by itself so you'll need to multiply x to both sides and then divide by sin(θ). This should give you the following: x = 10 / sin(θ)
Being that 1 / sin(θ) = cosec(θ), you can substitute 1 / sin (θ) for cosec(θ).
This would give you x = opposite •
cosec(θ) which is the same as x = 10 cosec (62°).
I apologize if I didn't explain that clearly enough :/ I hope it helps you out a lil bit though!
