James’ mom checks up on the plants every so often to ensure that they won’t die. However, she’s going on vacation for the next 15 days. If James forgets to water the plants for 3 or more days the plants will die. Find the probability that James keeps the plants alive. Also, let Y be the random variable corresponding to the number of days James forgets to water the plant (Y ≤ 3) describe the PMF of Y.

you need to show us the graph.

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.

m∠a is 90°

m∠b is 40°

113.42

i hope that is right.
