The frequency distribution for the weekly incomes of students with part time jobs is listed below. Construct the corresponding relative frequency distribution. Round relative frequencies to the nearest hundredth of a percent if necessary. Income ($): Frequency:
200-300 60
301-400 73
401-500 91
501-600 89
More Than 600 15

a. she will receive a refund of $278.

step-by-step explanation:

7,24

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.

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
