Answer:
It is a reflection of triangle 1 in the y-axis.
Step-by-step explanation:
The y coordinates are unchanged but the x coordinates have change sign.
Triangle 2 is the reflection of triangle 1 in the y-axis.
(5, 9 )
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), thus
(- 5, 9 ) → (5, 9 )
I think its 90
3x plus 1x is 4x divide 180 but 4 and get 45 so that meab there are 135 and 45
you need 90 more analysts to have a 1 to 1 ratio
1968
A= basexheight
= 48x41
= 1968
Units: If base and height are given in metres, units of area will be m².
If they are in cm, them unit of area= cm².
Answer: Mean = 20 and standard deviation = 4
Let x represents the success of getting the correct answer.
Here, the total number of trials(n) = 100
The probability of getting the correct answer, p = 1/5
Thus, the mean of the number of correct answer,
Now, the standard deviation,
Thus, First option is correct.
