Margie is practicing for an upcoming tennis tournament. Her first serve is good 20 out of 30 times on average. Margie wants to know the
estimated probability that her first serve will be good at least four of the next six times she serves. How could she design a simulation for
this scenario?
The scenario can be simulated by rolling a six-sided die times. The
would represent the number of
Margie's good first serves. If the
appear in a set of outcomes one time each, it would mean that at least four of
the next six first serves that Margie makes will be good.

OPTIONS?

Step-by-step explanation:

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

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.
