Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of grams and a standard deviation of grams while babies born after a gestation period of 40 weeks have a mean weight of grams and a standard deviation of grams. If a ​-week gestation period baby weighs grams and a ​-week gestation period baby weighs ​grams, find the corresponding​ z-scores. Which baby weighs relative to the gestation​ period?

Answers

Complete question :

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2800 grams and a standard deviation of 900 grams while babies born after a gestation period of 40 weeks have a mean weight of 3100 grams and a standard deviation of 410 grams. If a 32 ​-week gestation period baby weighs 3300 grams and a 40 ​-week gestation period baby weighs 3600 ​grams, find the corresponding​z-scores. Which baby weighs more relative to the gestation​ period? Find the corresponding​ z-scores. Which baby weighs relatively more​?

Answer:

32 - 35 weeks = 0.56

40 weeks : 1.22

40 weeks babies weigh more

Step-by-step explanation:

Given that :

32 - 35 weeks babies :

Mean (m) = 2800

Standard deviation (s) = 900

Weight (x) = 3300

40 weeks babies :

Mean (m) = 3100

Standard deviation (s) = 410

Weight (x) = 3600

Obtain the standardized score for both categories :

Zscore = (x - m) / s

32 - 35 weeks :

Zscore = (3300 - 2800) / 900

Zscore = 0.555555 = 0.56

40 weeks :

Zscore = (3600 - 3100) / 410

Zscore = 1.2195121 = 1.22

Zscore for 40 weeks is higher than 32-35 weeks.

Hence, 40 weeks babies weigh more.

Graph the line that passes through the two lines (1,5/2), (-1/2,-1/4)

Answers

Answer:

Image below

Step-by-step explanation:

Graph of a Line Given Two Points

We are given the points (1,5/2), (-1/2,-1/4).

A straight line is entirely defined by two points. We have to plot them and join them with a straight line ending in arrows.

The point (1,5/2) is converted to decimal as (1,2.5)

The point (-1/2,-1/4) is also converted to decimal: (-0.5,-0.25)

This helps to define the divisions of each axis and properly draw the line.

Please refer to the image below.

Suppose a binomial trial has a probability of success of 0.3, and 500 trials are performed. What is the standard deviation of the possible outcomes? Round
your answer to two decimal places.
O A. 10.25
OB. 8.94
O c. 6.71
D. 10.95

Answers

The standard deviation of the possible outcomes is to be considered as the 10.25.

Calculation of the standard deviation:

Since there is a binomial trial has a probability of success of 0.3, and 500 trials are performed.

So here

q = 1 - P

= 1 - 0.3

=0.7

Now the standard devation be like

[tex]= \sqrt{500\times 0.3 \times 0.7}[/tex]

=  10.25

hence, The standard deviation of the possible outcomes is to be considered as the 10.25.

You bought 5 chocolate bars and 8 blow pops for $23.25. Your sister bought 2 chocolate bars and 13 blow pops for $21.55. How much did each chocolate bar cost?

Answers

Answer:

$2.65

Step-by-step explanation:

Let chocolate bar cost = c and blow pops cost = b

As per given we have equations below:

5c + 8b = 23.25 2c + 13b = 21.55

13 times the first equation minus 8 times the second to eliminate b and find c:

13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55) 65c - 16c = 129.85 49c = 129.85 c = 129.85/49 c = 2.65

Each chocolate bar costs $2.65

First, let's form an equation. We'll represent the final depth of snow on Cherry Street with the variable d. We'll represent the hours with the variable h.

10 - 1/3h = d

Now, you already know what h equals so you can replace h with 3 for 3 hours.

10 - 1/3(3) = d

1/3 * 3 = 1.

10 - 1 = d

10 - 1 = 9

Now, we know what d equals.

10 - 1/3(3) = 9.

Do NOT forget the unit of measurement in your final answer, cm. In the photo, it looks as though it has already been provided.

The president of the Minneapolis Community College wonders if students who attend her college have a ACT scores that are significantly different from the ACT scores reported by the American College Teaching Corporation. The president would perform a ___________ test, and use a z-critical value of _____.

+/-1.96

Step-by-step explanation:

Following this claim, the president would have to perform a two tailed test. Since he wants to know if the Act scores of students in her school are significantly different from what is reported by the ACT corporation.

At a confidence level that is 95%, the level of significance is = 0.05. then the z critical value to be used would be +/- 1.96

Answers

Answer:

150 and -150

Step-by-step explanation:

For question number 2...

You started off with an energy level of 250 and something was added to make it 400.

To figure out what this "something" was, you simply subtract the numbers.

400 - 250 = 150

For question number 3...

You start off with 325 and end with 175. Here, the outcome is smaller or less than what you started with. So, you know that you took away a certain amount of energy. To figure that out, you again subtract.

325 - 175 = 150

To make the equation make sense, you would subtract 150.

So the answer would -150.

It says that I need to find x for the missing angle in the equation.
