Open1. What test/procedure did you perform? a. One-sided t-test c. Regression d. ​​Confidence interval Brain data. SETUP: It is believed that the person whose brain has larger surface area (i. e. TOTSA: Total Surface Area) that the person will have the larger brain volume as well. Given the data your job is to confirm or disprove this assertion. b. Two-sided t-test 2. What is the P-value/margin of error? a. 0.248605264 b. 0.005070081

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.
