Answer:
-7
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-2-(-9))/(2-3)
m=(-2+9)/-1
m=7/-1
m=-7
Answer:
Yes Maggie has enough money to purchase the dress and hair accessory.
Step-by-step explanation:
Dress = $35.75
Hair accessory = $2.80
Total amount of money = $40
Does her have enough money?
Total Money in pocket - (Dress cost + hair accessory)
$40.00 - ($35.75 + 2.80)
$40.00 - ($36.00 + $3.00) Round to the nearest dollar
$40.00 - $39.00 = $1.00
Yes
Answer:
Step-by-step explanation:
Let X be average interest paid monthly by a bank's Visa cardholders
Given that X is N(28, 8)
In the following to find out probability we convert X to z score and use std normal distribution table
Z = ![\frac{x-28}{8}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-28%7D%7B8%7D)
Probability being less than 1 is here equal to the proportion also.
A) P(X>32) = P(Z>0.5)=0.5-0.1915=0.3085
B) P(X>40) = P(Z>1)=0.5-0.3413=0.1687
C) P(X<19) = P(Z<-1.125)=0.5-0.0438=0.4562
D) We have to find 19th percentile here
Z =-0.88
Since the car costs $117 a day and you are going on a three day road trip, then you would do 117 x 3 = 351.
Subtract 351 from the total cost 373 - 351 = 22
To find out how many additional miles you drove, 22/0.22 = 100
So you drove 100 additional miles.
