The interval 44-47 has a frequency of 3 . The interval 48-51 has a frequency of 4. The interval 56-59 has a frequency of 1. The given data set is: 42, 43, 46, 47, 47, 48, 49, 50, 51, 53, 55, 55, 59 The number lying in the interval 44-47 are :46, 47, 47 So the interval 44-47 has a frequency of 3. The number lying in the interval 48-51 are :48, 49, 50, 51 So, the interval 48-51 has a frequency of 4. The number lying in the interval 56-59 is: 59 So, the interval 56-59 has a frequency of 1.
If the triangle is only moving 5 units to the right, then the Y coordinate doesn't change; it doesn't go up or down, only left or right. To find the X coordinate, you only need to add 5. Since you're moving to the RIGHT, then the value of X would be greater. -1+5=4. And since the value of y stays the same, your final answer would be A'=(4,3)
2.)68 3.) 2.75 4.) to be proportional the line must start threw the origin and be linear. This graph starts threw the origin as is linear which means it is proportional Sorry if it’s wrong. Hopefully I helped!!
