Jake's teacher had 6 calculators for 28 students to use. if the first students to use the calculators are chosen at random, what is the probability that jake will get one?

or 21.45%

Step-by-step explanation:

To find the probability that Jake will get a calculator, we simply divide the number of calculators to the number of students in the class.

Probability =

Probability =

To find the probability in percentage form, we simply multiply the quotient of by 100

0.2142 x 100 = 21.42%

So Jack has a 21.45% chance of getting a calculator from the teacher.

answer: i don't understand it

step-by-step explanation: sorry

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.
