Let x = amount for dog
let 2/3x-5 = amount for cat
x + 2/3x-5 = 195 combine x's
1 2/3x or 5/3x
5/3x-5 =195 add 5 to both sides
5/3x = 200 multiply both sides by 3
5x = 600 divided both sides by 5
x = 120
the cost of the dog is $120.00
Answer:
Basically find the unit rate by doing 3.99/24 = $0.16625/1oz
1 quart = 32 ounces so 4.8/32 = $0.15/1oz
1 gallon = 153.722 ounces so 11/153.722 = 0.07
49.6/768.61 = 0.06
Step-by-step explanation:
D.
Answer:
z = -0.577
Step-by-step explanation:
sample mean = ( 24.3 + 24.9 + 24.8 ) / 3 = 24.667
n = 3
σ = 1.0
Test statistic:
z = ( 24.667 - 25 ) / ( 1/SQRT(3) )
z = -0.577
4) fifteen less than y is 32
15 - y= 32
15 - (-17)= 32
two negatives become positive so 15+17= 32
Part A:
Given that 47% of adults prefer milk chocolate to dark
chocolate, for a random sample of n = 4 adults, the probability that all four adults say that they
