→ Question 11 → Give an example where one person's account balance is $30 better then another's , yet both have to be a negative balance Question 12 → Which expressions can be used to find the distance between x and 8 ? →x - 8
→[x +8]
→x -(-8)
→[8 -x ]
→[x -(-8)]
→[x - 8]
Question 13 → Which expression can be used to find the distance between x and -12 ?
→x -12
→[x - 12]
→x - (-12)]
→[-12 - x]
→[x - (-12)]
→[-x - 12 ]

that there are 12 data points

step-by-step explanation:

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

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.
