Bianca wrote the steps for her solution to the equation 2.3 + 8(1.3x – 4.75) = 629.9. She left out the description for the last step. A table titled Bianca's Solution with 2 columns and 5 rows. The first row has the entries, blank, Steps, Resulting equations. The second row has the entries, 1, Use the distributive property to simplify, 2.3 plus 10.4 x minus 38 equals 629.9. The third row has the entries 2, Combine like terms, 10.4 x minus 35.7 equals 629.9. The fourth row has the entries, 3, Use the addition property of equality, 10.4 x equals 665.6. The fifth row has the entries, 4, blank, x equals 64. What is the missing step of her solution?

lol

step-by-step explanation:

a precentage of 6th graders. the population is all 6th graders. let me know if i'm wrong, i hope this ! : )

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.
