Find the mean and medain which measures of center best repersents the data 80,90,10,75,90,95,99
A. The mean
B. The median
C. both mean and median
D. Neither the mean or the median

median

Step-by-step explanation:

There is a drastic outlier which makes the median the best measure of center for this data

19.side- angle- side

20. angle- side- angle

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
