Answer:
Step-by-step explanation:
Unless I'm reading this incorrectly, he throws 155 6's.
There are 1000 throws altogether (according to the table)
So the experimental probability is 155/1000 = 0.155
The answer is B. It is a bit tricky to read.
Determine the equation of the line of best fit. Write your answer in slope-intercept form. Any non-integers in this problem should be entered as decimal numbers. Round to three decimal places when necessary.
a) Yes the slope makes sense, as the players foot length gets larger, their overall height also increases signifying that there is a correlation between foot size and height.
b) The y-intercept occurs when the line "intercepts" the y-axis. It also makes sense because a player that has 25 cm in distance from heel to toe may very likely be 1.55 meters in height. This is probable.
c) The equation of any line is:
y=mx+b (m= slope, b= y-intercept)
The slope of this line can be found by locating two points where the line intersects. I will use points (25.5,1.6) and (26.25,1.7).
The formula to find the slope is (y(2)-y(1)) / (x(2)-x(1)) = m
1.7 - 1.6 / 26.25 - 25.5 = .1/.75 = .13333
This line crosses the y-intercept at about 1.55m
The equation of this line is:
y = .1333 x + 1.55
Answer:
y = 0.133x - 1.791
Step-by-step explanation:
The points (27, 1.8) and (27.75, 1.9) lie on the line of best fit. Use these points to find the slope:
m = y2 - y1 1.9 - 1.8 0.1
------------- = ----------------- = -------- = 0.133
x2 - x1 27.75 - 27 0.75
Plug the value of the slope into the equation of the line y = mx +b to get .
y = 0.133x + b
Substitute the point (27, 1.8) into the equation and solve for b:
1.8 = 0.133(27) + b
b = -1.791
Plug the value of b into the equation of the line of best fit to get:
y = 0.133x - 1.791

Answer:
I think that you should collect the both fracrions
Step-by-step explanation:
The smallest common multiple of 2 and 12 is 12
so:
1*6/2*6+ 8/12= 6/8 + 8/12= 14/12

Round your answer for the standard error to three decimal places.
mean=______
standard error=_______
(b) Is the sample size large enough for the Central Limit Theorem to apply?
1. Yes
2. No
The standard error of the distribution of sample proportions is 0.056 and mean is 0.15.
Yes, the sample size is enough for the Central Limit Theorem to apply.
(a). Given that, size of sample,
Proportion,
In the distribution of sample proportions, mean
and, standard error =
So, mean
Standard error =
(b). The Central Limit Theorem applies if np > 5 .
Thus, the Central Limit Theorem is applied.

Answer:
a) The mean is 0.15 and the standard error is 0.056.
b) 1. Yes
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For proportions p, in samples of size n, the mean is and the standard error is . The Central Limit Theorem applies is np > 5 and np(1-p)>5.
In this question:
So
(a) Find the mean and the standard error of the distribution of sample proportions.
So the mean is 0.15 and the standard error is 0.056.
(b) Is the sample size large enough for the Central Limit Theorem to apply?
np = 40*0.15 = 6 > 5
np(1-p) = 40*0.15*0.85 = 5.1>5
So yes
Answer:
The answer is 5.8 times a second
Step-by-step explanation:
Divide 1044 by 180 (The number of seconds in 3 minutes)
To calculate the rate in revolutions per second, we first convert the 3 minutes into seconds, which is 180 seconds. We then divide the total number of revolutions, 1044, by 180. This gives us a rate of 5.8 revolutions per second.
To solve this problem, we need to convert minutes into seconds because the rate is asked in revolutions per second.
Let's start by figuring out how many seconds are in those 3 minutes. We know that in 1 minute, there are 60 seconds. So, 3 minutes would be 3 times 60, which is 180 seconds.
Next, we will calculate the rate by dividing the total number of revolutions, which is 1044, by the total number of seconds, which is 180. So, 1044 ÷ 180 = 5.8.
This means that the propeller spins at a rate of 5.8 revolutions per second.
