Suppose that a software development team released an update to one of their mobile applications after receiving complaints
about the previous version from 10.6% of their customers. A few weeks after the update was released, the development team
wanted to know if fewer customers had complaints. The team selected a random sample of 350 customers and found that 22
of them submitted complaints about the application after the update was released.
The team wants to use a one-sample z-test for a population proportion to see if the proportion of customers with complaints,
p, has decreased since they released the update. For this test, they plan to use a significance level of a = 0.01.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

1) letter c.

2) 4 square root of 9

hope this

step-by-step explanation:

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
