Answer:
Sample size should be atleast 617
Step-by-step explanation:
given that a 95% confidence interval for the mean of a population is to be constructed and must be accurate to within 0.3 unit.
i.e. margin of error <0.3
Std devition sample = 3.8
For 95% assuming sample size large we can use z critical value
Z critical = 1.96
we have
Sample size should be atleast 617 to get an accurate margin of error 0.3
360=24%0f x
360=24/100*x
360*100=24x
36000/24=x
therefore, x=1500......
Answer:
y = 4x - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 4x - y = 1 into this form
add y to both sides
4x = y + 1 ( subtract 1 from both sides )
4x - 1 = y
y = 4x - 1 ← in slope-intercept form
Answer:
Step-by-step explanation:
A group of 2 hot dogs and 1 soda makes a group of 3 items. There were ...
234/3 = 78
groups of items sold.
Since there is 1 soda in the group, that's 78 sodas. The number of hot dogs is 2 times that, or 156 hot dogs.
78 sodas and 156 hot dogs were sold.
