Suppose that the amount of a weekly grocery bill of all households in a metropolitan area is distributed with a mean of $140. In a random sample of 49 households selected from this metropolitan area, the sample standard deviation is $35. (Use applet!) a. What statistic is used to analyze this situation? b. Find the statistic and probability that average amount of grocery bill of such a sample will be: i. more than $145, ii. less than $140, iii. between $132 and $148

use context clues to figure out the meaning of the bolded word:  

the sage gardener knew when she had to water her plants.  

question 8 options:

mint plant

wise

happy

lazy

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

6 and 24

step-by-step explanation:

6 x 4 = 24
