The first one because you distribute -1
To find the decimal form of 12/20, we do:
12/20= 0.6
Answer:
Define two roughly identical sets.
Reduce the chance of bias.
Step-by-step explanation:
In this experiment, Daniel performs a random assignment in order to stablish two separate groups with roughly equivalent ability to do barbell curls. Two different treatments (verbal encouragement and silence) are then applied in order to verify for a cause and effect relationship. If the groups were not randomly assigned, then the experiment could be biased.
Answer:28
Step-by-step explanation:
To find area you need to take the 7 and 4 and multiply them together to get your answer.
The dilation is a transformation in which the size of the preimage is
reduced by 0.5.
- The coordinates of the point Q' following the dilation of the point Q(0, 2) is
![\underline{Q' = (0, \, 1)}](https://tex.z-dn.net/?f=%5Cunderline%7BQ%27%20%3D%20%280%2C%20%5C%2C%201%29%7D)
Reasons:
The given rule for the dilation of QRST to the image Q'R'S'T' is presented as follows;
(x, y) = (0.5·x, 0.5·y)
The coordinates of the point Q' following a dilation of the point Q(0, 2) by
is therefore;
Q(0, 2)
(0.5 × 0, 0.5 × 2) = Q'(0, 1)
- The coordinates of
![\underline{Q' = (0, \, 1)}](https://tex.z-dn.net/?f=%5Cunderline%7BQ%27%20%3D%20%280%2C%20%5C%2C%201%29%7D)
