Answer:
13a
Step-by-step explanation:
9a + 3a + a = 13a
Answer:
it has to be 36
Step-by-step explanation:
the question doesnt make sense like at all, like there really isnt much information. But if you do look at it, AC and AB dont have that big of a difference in length... if AC= 48, then logically AB=36... or maybe its "none of the choices are correct" I hope im right, but just in case look it up on google or something. Good luck!
I know one of them is 1/2
Looking at the given triangle, we can see that it is a right angle triangle since one of the angles is 90 degrees.
For the circular water bowl to touch each side of the triangle, the center of the circular bowl would be determined by bisecting each of the angles at the vertices of the triangular table top. Therefore,
the correct option is the second one
Answer:
See below
Step-by-step explanation:
The independent variable should be the size and the dependent variable the price.
This is the most logical approach if the manager wants to have an idea about what price could be adequate for future models with different sizes.
The first thing to do if we want to determine if there appears to be a relationship between the variables is to draw the scatter plot
<h3>(See picture attached)
</h3>
From the scatter plot we can tell that there is an apparent directly proportional relationship between size and price (the larger the size, the larger the price).
We could now try and compute the Pearson correlation coefficient r given by
where
are the sizes
are the prices
n = number of observations (7)
If we did so, we would find that<em> r = 0.9</em>, which tells us that there is a good linear correlation between size and price.
