7 + 5 + 2 = 14 because seven plus five is twelve, twelve plus two is fourteen.
Answer:
r is 1 5/8
Step-by-step explanation:
3 3/4 is the same as 3 6/8, now both denominators are the same.
5 3/8 - 3 6/8 is the same as 43/8-30/8 which is 13/8, or in mixed number form, 1 5/8.
So r=1 5/8

Here is my answer:
Number of days: 30
Mean of the data set = (68 + 70*2 +74*2 +76*4 +78 +80*5 + 82*3 +84*5 + 88 +88*3 + 92*3) /30 = 81

Answer:
Yes
Step-by-step explanation:
ΔMNL ≅ ΔQNL by ASA or AAS
by ASA
Proof:
∠ LNM = ∠LNQ =90
LN = LN {Common}
∠MLN = ∠QLN {LN bisects ∠ L}
By AAS
∠Q + ∠QLN + ∠LNQ = 180 {Angle sum property of triangle}
∠Q + 32 + 90 = 180
∠Q + 122 = 180
∠Q = 180 -122 =
∠Q = 58
∠Q = ∠M
∠MNL =∠QNL = 90
LN = LN {common side}
