For a chad drives 56 miles per hour. you got this by dividing 168 by 3.
for b it takes chad 12 hours and you got this by dividing 672 by 56.
for c, chads car gets 28 miles per gallon you got this by dividing 308 by 11
for d, chads car uses uses 24 gallons to travel 672 miles an you got this by dividing 672 by 28. hope this is right.:)
Answer:
I think that there is indefinite.
Step-by-step explanation:
The reason why is because <em>x and y </em>could be any number
You multiply the whole number by the denominator and then add the numerator and get 344/100 then simplify and then you get 86/25 then now its a improper fractions so turn it into a mixed number and its 3 11/25
This is Pythagorean theorem, a^2+b^2=c^2 , a = 33 and c = 37 so b^2 + 1089 = 1369 , b^2 = 280 , b = 16.73m
Answer:
0
Step-by-step explanation:
H0 : μ = 840
H1 : μ < 840
Sample size, n = 49
Standard deviation, s = 14
Test statistic = (xbar - μ) ÷ (s/√(n))
Test statistic = (830 - 840) ÷ (14/7)
Test statistic = - 10 / 2
Test statistic = - 5
The Pvalue ;
Pvalue = P(Z < - 5) = 0 (Z probability calculator)
The Pvalue = 0
