Which summation formula is equivalent to the one below?​

Answers

Answer:

The second summation, counting from the top.

Step-by-step explanation:

Remember the relation:

[tex]a^{-n} = \frac{1}{a^n}[/tex]

The first summation is:

4*(  (-1/2)^0 + (-1/2)^1 +  (-1/2)^2 + (-1/2)^3)

4*( 1 - 1/2 + 1/4 - 1/8) = 2.5

Now let's analyze the options.

Let's look at option A, here we only have 2 to different powers, so we never can have a summation equal to 2.5, then we can discard that option.

Let's look at the next one (B), it will be equal to:

= (1/4)*( (-2)^4 + (-2)^3 + (-2)^2 + (-2)^1) =

= (1/4)*( 16 - 8 + 4 - 2) = 2.5

Then this summation is the one equivalent to the first one.

The table is a quadratic function

Step-by-step explanation:

Given

The attached table

Required

Tell if it is a quadratic function

The difference in the x values are uniform (i.e. difference of 1), so the following method can be applied.

(1) Subtract adjacent y values.

[tex]d_1=2 - 16 = -14[/tex]

[tex]d_2=-2 - 2 = -4[/tex]

[tex]d_3 = 4--2 = 6[/tex]

[tex]d_4 = 20 - 4 = 16[/tex]

(2) Subtract adjacent differences in (1) above

[tex]d_5 = d_2 - d_1 = -4 --14 = 10[/tex]

[tex]d_6 = d_3 - d_2 = 6 --4 = 10[/tex]

[tex]d_7 = d_4 - d_3 = 16 -6 = 10[/tex]

Notice the calculated differences in (2) are the same.

Hence, the table is a quadratic function

The Athens-Clarke Country Wildlife Resource Center wanted to encourage wildlife preservation efforts among students in its summer camp. In the past, it would run a particular curriculum, then gauge students' interest in wildlife preservation in a test at the end of the camp. Historically, the average on this final test to gauge preservation interest was 35.3 (out of 100).

Last summer, the resource Center created a new curriculum focusing on campers interacting directly with wildlife to promote preservation efforts. This included efforts in species dentrication handling of wild animals, and directoration of animals in habitat The Resource Center considers the collection of 40 to be a random samping from the population of campers they will encounter They need your help to determine whether this new curriculum Improves impressions about witte preservation. For their 40 scores at the end of lut summer, they found a sample mean of 26.58 and a standard deviation of 3.18.

C. g(x) = (1/2x)²
D. g(x) = 1/4x²

Answers

Answer:

B. g(x) = (1/4x)²

Step-by-step explanation:

g(x) experiences a horizontal stretch where 0<|a|<1

This means we can eliminate A because that would be a horizontal compression since |a|>1

B seems to work because (1/4(4))^2=1

C does not work because you'll get 2 as your y-value

D does not work because you'd be taking 1/4 of x^2 which would give you 4.

To graduate this semester, you must pass Statistics 314; and you estimate that you have an 85% chance of passing. You need to pass Math 272 or Math 444, each of which you have an 80% chance of passing: so you will take both in hopes that you will pass at least one. Further, you must pass German 320, which you believe you have a 90% chance of passing. Assuming your chances of passing each class you take are independent, what is your probability of graduating this semester

Answers

Answer:

Probability of graduating this semester is 0.7344

Step-by-step explanation:

Given the data in the question;

let A represent passing STAT-314

B represent passing at least in MATH-272 or MATH-444

M1 represent passing in MATH-272

M2 represent passing in MATH-444

C represent  passing GERMAN-32

now

P( A ) = 0.85, P( C ) = 90, P( M1 ) = P( M2 ) = 0.8

P( B ) = P( pass at least one of either MATH-272 or MATH-444 ) = P( pass in MATH-272 but not MATH-444 ) + ( pass in MATH-444 but not in MATH 272) + P( pass both )

P( B ) =  P( M1 ) × ( 1 - P( M2 ) ) + ( 1 - P( M1 ) ) × P( M2 ) + P( M1 ) × P( M2 )

we substitute

⇒ 0.8×0.2 + 0.2×0.8 + 0.8×0.8 = 0.16 + 0.16 + 0.64 = 0.96

∴ the probability of graduating this semester will be;

⇒ P( A ) × P( B ) × P( C )

we substitute

⇒ 0.85 × 0.96 × 90

0.7344

Probability of graduating this semester is 0.7344

Ryan just got hired for a new job and will make $48,000 in his first year. Ryan was
told that he can expect to get raises of $3,500 every year going forward. How much
money in salary would Ryan make in his 24th year working at this job?

Answers

Answer:

$128,500

Step-by-step explanation:

Find out how much he will earn from his 1st year to 24th.

1st year = 48000

2nd year = 48000 + 3500 = 51500

3rd year = 51500 + 3500 = 55000

4th year = 55000 + 3500 = 58500

5th year = 58500 + 3500 = 62000

6th year = 62000 + 3500 = 65500

7th year = 65500 + 3500 = 69000

8th year = 69000 + 3500 = 72500

9th year = 72500 + 3500 = 76000

10th year = 76000 + 3500 = 79500

11th year = 79500 + 3500 = 83000

12th year = 83000 + 3500 = 86500

13th year = 86500 + 3500 = 90000

14th year = 90000 + 3500 = 93500

15th year = 93500 + 3500 = 97000

16th year = 97000 + 3500 = 100500

17th year = 100500 + 3500 = 104000

18th year = 104000 + 3500 = 107500

19th year = 107500 + 3500 = 111000

20th year = 111000 + 3500 = 114500

21st year = 114500 + 3500 = 118000

22nd year = 118000 + 3500 = 121500

23rd year = 121500 + 3500 = 125000

24th year = 125000 + 3500 = 128500

A study9 compared personality characteristics between adult children of alcoholics and a control group matched on age and gender. For the 29 pairs of women, the authors reported a mean of 24.8 on the well-being measure for the children of alcoholics, and a mean of 29.0 for the control group. They reported t = 2.67 for the test comparing the means. Assuming that this is the result of a dependent-samples analysis, identify the df for the t test statistic, report the P-value, and interpret.

Answers

Answer:

df.= 28

P - value = 0.0124 < 0.05

There is a difference between the mean of  the well-being measure for the children of alcoholics, and a mean of the control group.

Step-by-step explanation:

As the given test is dependent or paired test the degrees of freedom is n-1 = 20-1 = 28

The reported t = 2.67

The P value for ∝= 0.05 at  calculated t= 2.67 and 28 d.f is 0.0124 which is less than 0.05 .

The null hypothesis is rejected.

The null hypothesis is that there is no difference between the means of the two samples.

H0: u1 = u2

The alternate hypotheis is accepted that there is  difference between the means of the two samples.

Ha: u1≠ u2

There is a difference between the mean of  the well-being measure for the children of alcoholics, and a mean of the control group.

Behind the guns, and tanks, and ships, and planes, are the blast furnaces and open hearths, the electric furnaces and blooming mills. Tending these giant furnaces have always stood a breed of men apart, giants in the land, those men of steel. But with our country in peril, the women of America rallied to the support of their men, and here in this, almost the last great industry we thought could be handled only by men, these mothers, wives, and sweethearts came to stand shoulder to shoulder with them in almost every capacity. These marvelous women of America. These women of steel. Of course, we had long since accepted their aptitude in fabrication, the swift, sure dexterity of their fingers, as in this stainless steel rib assembly. Their adaptability to small tools. Even the hand welding electrodes. But as the need grew for more and more production of the basic metal itself, more loyal women with a dash a true American pluck and venturesomeness, edged further and further into the real work of steel making. Some with a scientific bent, went into metallurgical control and research labs-- girls fresh from chemical engineering school, older women who had been technical librarians. Yes, women make good inspectors. Here's one applying the magnaflux test to steel for airplane motors. They make good drivers too.American girls raised to drive the family car find it no trick at all to handle trucks and tractors. Mrs. Warner at these crane controls must lift this huge bloom into the furnace to be heated red hot, then carried across the shop to the forging press. It takes good judgment and a steady hand to manipulate it under the drop hammer-- just the right amount and position each time. And Ms. Evans here is very adept at this. Here is the office of the supervisor of women employees. She can tell us more about it. If you will, Ms. Campbell. MS.CAMPBELL: Women in steel are simply the result of realistic thinking.In time of war, you have to have steel. You also have to have people to make it. With the Army taking men by the thousands-- more than 16,000 from our plant so far-- we had to find people to replace them. A great untapped reserve was women.NARRATOR: How many do you have?MS. CAMPBELL: About half of the replacements are women, more than 8,000 of them. The rest are older men and young boys.NARRATOR: And the women, are they doing all right?MS. CAMPBELL: Beyond anything anyone ever dreamed of. They're doing something in almost every department in the plant. And I don't mean just clerks and checkers. We have women engineers and oilers in the boiler room. Women repair experts. Women work at the oil mines above ground. Along the unloading docks. And our private railroad tracks. Women carpenters. And women shipbuilders. And women load and unload our freight cars. We have girls in charge of our tool cribs, and that takes the knowing of a lot of tools to do that.
