M∥n, m∠1 = 50°, m∠2 = 48°, and line s bisects ∠ABC. What is m∠3?
Nutka1998 [239]

Answer

m<3  = 49°

Step-by-step explanation:

It is given that,


M∥n, m∠1 = 50°, m∠2 = 48°, and line s bisects ∠ABC


m<DEF = m<1 + m<2 = 50° + 48° = 98°


Corresponding angle of <DEF is equal to <ABC = 98°


To find m<3


< 4 = <5 = 98/2 = 49° (Since line s bisects ∠ABC)


Therefore,

m<3 = 49°  (< 4 and <3 are vertically opposite angles)

An English professor determined the mean of her final exam scores to be 78 with a standard deviation of 6.3. Find the minimum an
Morgarella [4.7K]

Solution: We are given:

Mean =78, Standard-deviation =6.3

We know that a usual values of the test scores falls within 2 standard deviation from the mean.

Therefore, the minimum usual test score is:

Mean - 2 Standard-deviation

78-2 \times 6.3

78-12.6

65.4

The maximum usual test score is:

Mean + 2 Standard-deviation

78+2 \times 6.3

78+12.6

90.6

Therefore, the minimum and maximum “usual” values of the test scores are:

65.4 and 90.6

Answer:

m = (n/3) - k

Step-by-step explanation:

n = 3(k + m)

n = 3k + 3m

n - 3k = 3m

3m/3 = (n - 3k)/3

m = (n/3) - k
