You scored the following grades on your first three math tests: 71.78, 81. You only have one test remaining. What is the highest possible test average
you can get?

Answers

Answer 1

Answer:

82.5.

Step-by-step explanation:

That would be the average if you scored 100 on your last test.

This is (71+78+81+100)/ 4

= 82.5

A bakery sells cakes, cookies, and pastries. They wonder if customers are equally likely to buy each product. They take a sample of 200 recent purchases and record what was purchased (they are willing to treat this as a random sample). Here are the results

Product Cakes Cookies Pastries
Observed purchases 65 68 67

They want to perform a x^2 goodness-of-fit test to determine if these results suggest that one type of product is more popular than the others. What is the expected count of cake purchases?

Answers

Answer:

66.667 cakes

Step-by-step explanation:

The expected count or value in a goodness of fit test is the product of the expected percentage and the total count or sample size.

Since the samples are being treated as a random sample, hence, the expected percentage of each of cake, pastries and cookies is the same.

The expected count of cakes is :

100/3 % * sample size

33.3333% * 200

= 66.667 cakes

does anyone know w(t) = 3t - 1, w(-4.2) ?

Answers

Answer:

w(-4.2) = 3(-4.2) -1 = -12.6 - 1 = -13.6

Step-by-step explanation:

The w(-4.2) is your t so you substitute it in your expression which means you get 3(-4.2) -1 and that gives you -13.6.

Line p passes through points (5,-4) and (2,7). What is the slope of a line that is perpendicular to line p

Answers

Answer:

3/11

Step-by-step explanation:

First find the slope of the line

m = (y2-y1)/(x2-x1)

    = ( 7 - -4)/(2 - 5)

    = (7+4)/(2-5)

   =11/ -3

We want a line that is perpendicular, so it is the negative reciprocal

-1 / ( -11/3)

+3/11

Angel signed up for a streaming music service
that costs $11 per month. The service allows
Angel to listen to unlimited music, but if he
wants to download songs for offline listening, the
service charges $0.50 per song. How much total
money would Angel have to pay in a month in
which he downloaded 25 songs? How much
would he have to pay if he downloaded s songs?

Answers

Answer:

Cost for 25 songs: $23.50

Cost for s songs: .50(s) + 11

Step-by-step explanation:

To solve this problem, we can make an equation in slope-intercept form:

y = mx + b

y represents the total amount of $.

m represents the cost of each song downloaded, or $.50

x represents the number of songs, or 's'

b represents the $11, or the constant.

We have the equation:

y = .50(x) + 11

If Angel downloaded 25 songs, we have the equation:

y = .50(25) + 11

We get y = $23.50

What does it mean to have a skewed distribution? What causes a skew in statistical terms? And how does one deal with skewed data when conducting research? Are there specific types of
research questions and types of data where one would expect the data to be skewed?

Answers

Answer:

Explained below

Step-by-step explanation:

A) A skewed distribution in a dataset is when the median is not equal to the mean in such a manner that the bell curve is tilted to the left or right.

B) If in a data set, there are outliers which are extremely large or extremely small in comparison to other values in that same dataset, then we can say that such a curve will be pulled towards the outlier and thus the distribution is skewed.

Also, if the curve is inclined to the left, it means there are few extreme values to the left and is is negatively skewed.

Similarly, if the curve is inclined to the right, it means there are few extreme values to the right and is positively skewed.

C) Example of a research question is;

If in a developed country where the poverty level is about 0%, if we collect the data of income of the households, we will discover majority of people with average income and very few people with extreme high levels of income. This condition means the data to is positively skewed.

How much work is done lifting a 35 pound object from the ground to the top of a 25 foot building if the cable used weighs 2.5 pounds per foot

Answers

Answer:

3400 ft-lbs

Step-by-step explanation:

The Workdone in lifting the rope :

Number of feet = x

Distance = 25 feets

2.5x + 35

Taking the integral :

∫2.5x + 35 dx at x = 40

Integrating, we have :

1/2(2.5x² ) + 35x at x = 40

1/2(2.5(40)²) + 35(40)

1/2(4000) + 1400

2000 + 1400

= 3400

Hence, Workdone in lifting the rope = 3400 ft-lbs

Answer:

6 1/4

Step-by-step explanation:

When you look at the bar graph at the top, you will see that there are 5 of 1 1/4.

If you multiply 5 by 5/4 (which is 1 1/4 converted to an improper fraction), you get 25/4. To convert that to a mixed number, divide 25 by 4 and put the remainder over 4. The final answer should be 6 1/4.

For the X's, just count how many of each number is in the graph above. For example, there should be 2 X's over 1, 5 X's over 1 1/4, 2 X's over 1 1/2, and 2 X's over 1 3/4.

A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of bolts. The sample mean bolt length was centimeters. The population standard deviation is known to be centimeters.
What is the test statistic z?What is the p-value?Does sufficient evidence exist that the length of bolts is actually greater than the mean value at a significance level of α=0.1?

Answers

Answer:

There is sufficient evidence. A further explanation is provided below.

Step-by-step explanation:

According to the question,

The alternative as well as null hypothesis will be:

[tex]H_0:\mu = 16[/tex]

[tex]H_a:\mu>16[/tex]

The test statistics will be:

⇒ [tex]z = \frac{\frac{\bar x - \mu}{\sigma} }{\sqrt{n} }[/tex]

By putting the values, we get

⇒    [tex]=\frac{\frac{16.06-16}{0.24} }{\sqrt{96} }[/tex]

⇒    [tex]=\frac{\frac{0.06}{0.24} }{\sqrt{96} }[/tex]

⇒    [tex]=2.45[/tex]

Or,

The p-value will be:

= 0.0071

i.e.,

⇒ [tex]p-value< \alpha[/tex]

Thus the above is the correct answer.
