Solution:</h3>
A line of symmetry is a figure that can be <u>divided</u> in 2 equal parts.
- The first figure has 1 line of symmetry since it can be <u>divided</u> into 2 equal parts horizontally. (According to image)
- The second figure has 1 line of symmetry since it can be <u>divided</u> into 2 equal parts. (According to image)
We'll first convert the mixed fractions to "improper" and then get their product, since the area of a rectangle is the product of its length and width.
19. (X+5)-3
20. 2a
21.3b
22. 5y-5
23. 1/2n-15
Answer:
-16
Step-by-step explanation:
y = mx
-4 = 1/4x
Divide both sides by 1/4.
-16 = x
Answer:
A) The relative frequencies in the table are reasonably close; C) The relative frequency of rolling an even number is 0.51.
Step-by-step explanation:
The relative frequencies given are at most 0.02 apart. This means they are reasonably close.
The theoretical probability for each outcome would be 1/4, or 0.25; this means the theoretical probability of rolling an even number would be 0.50, not 0.51.
However, the relative frequency of rolling an even number would be 0.24+0.27 = 0.51.
Since the relative frequencies are reasonably close, the number cube is likely to be fair.
