The average annual salary for all u. s. teachers is $47,750. assume that the distribution is normal and the standard deviation is $5680. find the probability that a randomly selected teacher earns a. between $35,000 and $45,000 a year
b. more than $40,000 a year
c. if you were applying for a teaching position and were offered $31,000 a year, how would you feel (based on this information)? How do you complete this problem?

step-by-step explanation:

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

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

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.
