A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a storm is in progress with a severe storm class rating. Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. The next 10 waves have an average wave height is 16 feet with a SD of .6 ft. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis
Answers
Answer:
The alternate hypothesis is:
[tex]H_{a} < 16[/tex]
Step-by-step explanation:
There are two types of hypothesis. The null hypothesis and the alternate hypothesis. The null hypothesis is that the mean found is equal to the expected value. The alternate hypothesis is a question about this expected value(different, more, less)
A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore.
This means that the null hypothesis is [tex]H_{0} = 16.4[/tex]
Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis
Dying down means lower average peak, that is, lower than the average of 16.4. This means that the alternate hypothesis is:
[tex]H_{a} < 16[/tex]

Step-by-step explanation:
So the little arrows on the lines means they are equal to each other so if you look, A to D and B to C have only one arrow meaning those two lines are the same lines
and A to B and D to C have two arrows meaning those two lines are the same
so that means if A to B is 9 and it's equal to the line D to C, then D to C is also 9
Hopefully this wasn't too confusing
Answer:
mCD = 9
Step-by-step explanation:
Because this polygon has opposite parallel sides, meaning each side across from each other are parallel, we know that this is a parallelogram. So:
AB ║ DC
BC ║ AD
Because this is a parallelogram, we know that, from the properties parallelograms, opposite sides of a parallelogram are congruent. This means that AB ≅ DC.
This also means that because AB = 9 and AB = DC, DC = 9.
Here's a mini two-column proof:
Statements → Reasons
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
mAB = 9 → Given
AB ║ DC, BC ║ AD → Given
ABCD is a parallelogram → Definition of a Parallelogram
AB ≅ DC → Opposite sides of a parallelogram are congruent.
mAB = mDC → Definition of Congruent Segments
9 = mDC → Substitution Property of Equality
mCD = mDC → Reflexive Property of Equality
mCD = 9 → Substitution Property of Equality

They have the ratio of sides from smallest to greatest: 1: √3 : 2
The top triangle
y = 2*7 = 14x = 7√3The bottom triangle
Acute angles n and 2n makes them 30° and 60°

a number increased by 9 is 13
Answers
Answer:
4
Step-by-step explanation:
To find the number you have to reverse the equation
Let us call the number "x"
x + 9 = 13
So to find x we flip the equation
13 - 9 = x
Solve it
4 = x
So the missing number is 4
Nutritionists measured the sugar content (in grams) for 32 drinks at Jake's Java
coffee shop. The drinks had a mean sugar content of 18g and a standard
deviation of 5g, and the distribution was roughly symmetric.
Question 1: Grande Mocha Cappuccino at Jake's Java contains 14 g of sugar.
Calculate the standardized score (z-score) for the Grande Mocha Cappuccino.
Answers
Answer:
[tex]z = -0.8[/tex]
Step-by-step explanation:
Given
[tex]n = 32[/tex] --- samples
[tex]\mu = 18g[/tex] --- mean
[tex]\sigma =5g[/tex] --- standard deviation
[tex]x = 14g[/tex] --- observed value
Required
Find the standardized score
This is calculated as:
[tex]z = \frac{x - \mu}{\sigma}[/tex]
So:
[tex]z = \frac{14g -18g}{5g}[/tex]
[tex]z = \frac{-4g}{5g}[/tex]
[tex]z = \frac{-4}{5}[/tex]
[tex]z = -0.8[/tex]
The standardized score is -0.8
