Answer:
5/3
Step-by-step explanation:
The two-way table is attached.
We know that 63 people took the survey, and 22 of them were left-handed. This means that 63-22=41 of them are right handed.
Out of the 63 total, 37 are left brain dominant; this means that 63-37=26 are right brain dominant.
Of the 26 that are right brain dominant, 21 are right handed; this means 26-21=5 are left handed.
Of the 22 left-handed people, 5 are right brain dominant; this means 22-5 = 17 are left brain dominant.
Of the 37 left brain dominant people, 17 are left handed; this means 37-17=20 are right handed.
Answer:
3x+10
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
There are 12 inches in 1 feet, so
5 feet = 5 * 12 = 60 inch
6 feet = 6 * 12 = 72 inch
So, we can say most adult humans are between 60 to 72 inches tall
The model is 7 inches tall. So, from the answer choices, 7 * 10 = 70 [the number that is in between 60 to 72]. Thus we can take the model to be 1/10th of the original.
So the scale factor is 1/10, or option B
Answer:
B) Parallelogram P'Q'R'S' is smaller than parallelogram PQRS, because the scale factor is less than 1.
Step-by-step explanation:
Given that Parallelogram PQRS is shown on the coordinate grid. Parallelogram PQRS is dilated with the origin as the center of dilation using the rule (x, y) → (0.75x, 0.75y) to create parallelogram P'Q'R'S'.
This means that sides of PQRS would be 0.75 times the sides of the original PQRS
Or PQRS will be larger
B) Parallelogram P'Q'R'S' is smaller than parallelogram PQRS, because the scale factor is less than 1.
is the right answer
