Answer:
The relationship is positive.
The model predicts a score of 60.
Not sure what part b is.
Step-by-step explanation:
Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.
By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.
A deck has 52 cards
A deck has 25 black cards.
A deck has 4 "4" cards but 2 of them are black, therefore 2 red
P(black or 4) = (25 + 2) / 52 = 27/52
the volume of a rectangular prism is just the product of its height, length and width.
let's firstly convert the mixed fraction to improper fraction and then multiply.
Hello!
First you have to find the ratio
To find this you put the sides of the triangles in a ratio and simplify it
Make sure you do the same side on each triangle
12 : 8
6:4
3:2
The ratio is 3:2
We do not know all three sides so we can use the SSS postulate
This tells use the answer is the SAS postulate with a ratio of 3:2
The answer is D) SAS; 3:2
Hope this helps!
Because the dilation is at the origin (0,0) multiply the coordinates by the scale factor.
L is at (-2,5) now.
The new location would be (-2 * 4 , 5 *4) = (-8,20)
