Answer:
The answer is what you would get when you do 4 1/2 x 2/9 which equals to 1 day!
so if 4 hours of math is 186, one hour is 46.5, therefore when you write a liner equation, you start with y=46.5x and then multiply 19 by 46.5
Answer: she should by 9 bottles of juice
Step-by-step explanation:
because there's 2 L per one bottle, 2L (X bottles) = 18L, X = 9
Answer:
X could equal 1, 2, 3, 6, 9, or 18
Step-by-step explanation:
Natural numbers include all whole numbers. (1,2,3,..etc)
Answer:
First we need to name some of the variables we are given:n = 38 the sample sizex = 6.88 the sample mean = 1.86 the population standard deviationWe need to find a 90% confidence interval for the mean price per 100 lbs of watermelon: = 1-.90 = .10/2 = .05z(/2) = -1.64-z(/2) = 1.64This can give us a probability expression:P(-1.645 < z < 1.645) = .90The margin of error is calculated with the formula: E = z(/2)(/√n)E = 1.645(1.86/√38) = $.4963(300) = $148.89 Then to calculate the upper and lower limit we add and subtract E from x:lower limit = 6.88 - .4963 = $7.38(300) = $2214upper limit = 6.88 + .4963 = $6.38(300) = $1914Note: We multiply the E, upper and lower limits by 300 because 15 tons is 30000lbs and we need the price per 100 lbs, so we divide 30000/100 and get 300.
