Answer:

unlikely

Step-by-step explanation:

There are 10 marbles altogether, 5 are yellow, 2 are blue, and 3 are random.

There are 3 more yellow marbles than blue marbles.

There is 1 more random marble than blue marbles.

Therefore, it is unlikely Jerome will get a blue marble.

(I just realized you asked for an Alegbra expression.. sorry)

Answer:

2) ∠SDH and ∠SDT are right angles because SD ⊥ HT.

3) \bar{SH}\cong \bar{ST} as it is given in the question.

4) \bar{SD}\cong \bar{SD}  is the reflexive property.

5) ΔSHD ≅ ΔSTD by RHS congruency.

Step-by-step explanation:

Given in the question:

\bar{SH}\cong \bar{ST}\\\bar{SD}\perp \bar{HT}

In ΔSHD and ΔSTD

\bar{SH}\cong \bar{ST}   (Given)

\angle SDH\cong \angle SDT=90^o    (SD ⊥ HT)

\bar{SD}\cong \bar{SD} (Common)

Therefore, \Delta SHD\cong \Delta STD   (By RHS rule)

Reflexive property of congruency is defined as the property in which something is equal to itself. Hence, the reflexive property of these two triangles is \bar{SD}\cong \bar{SD}
