Answer:
5/12 inches per minute
Step-by-step explanation:
If A snail crawls 5/8 inches in 3/4 minute, then;
5/8 inches = 3/4 minute
we are to fine the distance covered in a minute;
x inches = 1 minute
Divide both expressions
5/8x = 3/4
24x = 20
12x = 5
x = 5/12
Hence the snail covered 5/12 inches per minute
Well, first, let's label the variables for our equation:
240 Miles per day
Traveled for 4 days
_________________________________________
Now, let's set up an equation to help us:
240x = ?
Since they're trying to figure out how many miles the family traveled after 4 days, and, they're going 240 miles each day, we should plug in a 4 where 'x' is:
240 ( 4 ) = ?
Now, we multiply:
240
× 4
________
800
+ 160
________
960
Answer: The family traveled 960 miles in 4 days.

First add the fractions.
6/7 + 5/7 = 1 4/7
Then add the whole numbers
4 + 3 = 7
Then add the mixed number to the whole number
7 + 1 4/7 = 8 4/7
Your answer is 8 4/7
Answer:
Test statistic = - 3.354
We reject H0 and conclude that the growth rate of the new shrub is less than 3cm per week.
Step-by-step explanation:
H0 : μ = 3
H1 : μ < 3
The test statistic = (xbar - μ) / (s/ √n)
Xbar = 1.50
μ = 3
s = 3
n = 45
Test statistic = (1.5 - 3) / (3/ √45)
Test statistic = - 1.5 / 0.4472135
Test statistic = - 3.354
Pvalue, using the Pvalue from Z score calculator :
Pvalue = 0.00039826
α = 0.05
Pvalue < α ; We reject H0 and conclude that the growth rate of the new shrub is less than 3cm per week.
