You can put this solution on YOUR website!-12x+y=28
I need to find the ordered pair of the y-intercept and the x-intercept
-----------------
To find the x-intercept, let y = zero; then solve for x:
-12x + 0 = 28
-12x = 28
x = -7/3
-----------
To find the y-intercept, let x = zero; then solve for y
0+y = 28
y = 28

Top of the arc is the vertex.
Vertex occurs when x = -b/2a = -46/(-32) = 23/16 seconds.

x-intercept:
Let y = 0 and solve for "x":
(x+4)(2x-1)(x-1) = 0
x = 4 or 1/2 or 1
Those are the x-intercepts.

y-intercept:
Let x = 0 and solve for "y":
y = (0+4)(0-1)(0-1) = 4
that is the y-intercept

You can put this solution on YOUR website!Consider an infinite population with a mean of 160 and a standard deviation of 25. A random sample of size 64 is taken from this population. The standard deviation of the sample mean equals?
----------
s = 25/sqrt(64) = 25/8 = 3.125

Probability-and-statistics/286773: A random sample of 30 women drank an average of 15 cups of coffee per week, with the sample standard deviation equals to 3 cups. A upper limit of an approximate confidence interval with 95% of the population avg cup drunk is? 1 solutions

You can put this solution on YOUR website!A random sample of 30 women drank an average of 15 cups of coffee per week, with the sample standard deviation equals to 3 cups. A upper limit of an approximate confidence interval with 95% of the population avg cup drunk is?
-------------------------
sample mean = 15
---
standard error = E = t*s/sqrt(n)
E = invT(97.5 with df = 29)(3/sqrt(30)] = 2.0452*3/sqrt(30) = 1.1202
---
95% CI: 15-1.1202 < u < 15+1.1202
95% CI: 13.880 < u < 16.120

a. State the null and alternate hypothesis.
Ho: p >= 0.45
Ha: p < 0.45
---------------------------
b. Determine the rejection region for the decision rule.
invNorm(0.97) = -1.8808
Reject region is all z < -1.8808
-------------------------------------------
c. Which equation listed below would you use?
Equations were not listed.

stat test: z(150/400) = (0.375-0.45)/sqrt[0.45*0.55/400] = -3.0151
Provide a one sentence answer.
Since the test stat is in the rejection region, reject Ho.

Radicals/286715: h=-16t+vt+s A ball is tossed into the air from a height of 10 feet with an initial velocity of 12 feet /sec. Find the time t(in seconds) for the object to reach the ground.
#2 a baseball player releases a baseball at a height of 6 feet with an initial velocity of 46 feet/sec. find the time(in seconds) for the ball to reach the ground.

You can put this solution on YOUR website!h=-16t+vt+s A ball is tossed into the air from a height of 10 feet with an initial velocity of 12 feet /sec. Find the time t(in seconds) for the object to reach the ground.
----
h(t) = -16t^2 + 12t + 10
Solve: -16t^2 + 12t + 10 = 0
Modify: -8t^2 + 6t + 5 = 0
-8t^2 + 10t - 4t + 5 = 0
-2t(4t-5)-(4t-5) = 0
(4t-5)(-2t-1) = 0
Positive solution:
t = 5/4 second
-------------------------------
#2 a baseball player releases a baseball at a height of 6 feet with an initial velocity of 46 feet/sec. find the time(in seconds) for the ball to reach the ground.
----
Solve:: -16t^2 + 46t + 6 = 0
8t^2 - 23t -3 = 0
8t^2 - 24t + t - 3 = 0
8t(t-3) + t-3 = 0
(t-3)(8t+1) = 0
Positive solution:
t = 3 seconds

Probability-and-statistics/286706: 1. The manager of a driving school claims that the mean time taken to learn how to drive a car is 8 hours or less for all new drivers. A sample of 16 new drivers showed that the mean time taken by them to learn how to drive the car is 9.5 hours with a standard deviation of 1.5 hours. Test the manager’s claim at the 1% significance level.
a. Select the null and alternate hypothesis.
b. Determine the critical values of the test statistic.
c. What equation/formula would you use?
d. Using the statistical calculator or manual calculation what is the observed statistic and what is your decision regarding the null hypothesis. Provide a one sentence answer.

a. Select the null and alternate hypothesis.
Ho: u <= 8 hrs
Ha: u >= 8 hrs
------------------------------------
b. Determine the critical values of the test statistic.
invT(0.99 with df = 15) = 2.6042
------------------------------------
c. What equation/formula would you use?
t(9.5) = (9.5-8)/[1.5/sqrt(16)] = 4
---------------------------------------
d. Using the statistical calculator or manual calculation what is the observed statistic and what is your decision regarding the null hypothesis. Provide a one sentence answer.
Conclusion: Since the test statistic is in the reject interval,
reject Ho.
