In qrs, mq = 63, mr = 70, and ms = 47. which side of qrs is the shortest?

QR is the shortest side

Step-by-step explanation:

∡S is opposite to side QR

∡Q is opposite to side SR

∡R is opposite to side QS

Law of sines states:

QR/sin(∡S) = SR/sin(∡Q) = QS/sin(∡R)

Given that: ∡S < ∡Q < ∡R; then,  sin(∡S) < sin(∡Q) < sin(∡R)

In order to satisfy the law of the sines, side QR must be shorter than side SR, and side SR must be shorter than side QS.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
