THIS IS ALGEBRA 1 PLEASE HELP IM IN MIDDLE SCHOOL

1.80 + 3.72 (0.25 x b) = 13.02

Step-by-step explanation:

First, combine the "one-time" costs (the medium pendant and the medium chain)

1.80 + 3.72 = 5.52

Now, multiply the cost of the beads by the amount of beads you want

0.25 x 30 = 7.50

Now combine both costs to get the total cost

5.52 + 7.50 = 13.02

It would cost Tamara $13.02 to make a medium length necklace

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

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.
