Answer:

No Solution

Step-by-step explanation:

perimeter

2√6 - √15 = 4.9-3.9 = 1

-3√3 = -5.19 you can't have a negative length.

and because of that the answer is no solution to both perimeter and area.

if the teacher was just oddly trying to have you show what you know

P = 1+1+ -5.2 - 5.2 = -8.2

A 1x -5.2 = -5.2

Answer:

17,680 ft²

Step-by-step explanation:

Shaded area = entire shaded rectangle area - unshaded rectangle area - square area

A = 200(100) - 24(30) - 40²

A = 20,000 - 720 - 1600 = 17,680

9514 1404 393

Answer:

  AC = 25

Step-by-step explanation:

The product of the near and far distances from C to the circle is the same for each segment. For segment CD, the near and far distances are the same. So, we have ...

  CD² = CB·CA

  CA = CD²/CB = 15²/9 = 25

The length AC is 25 units.

_____

It seems possible that in some other versions of this question you might be asked to find x. Then you have ...

  AB = AC -BC = 25 -9 = 16

  3x +1 = 16 . . . substitute for AB

  3x = 15 . . . . . subtract 1

  x = 5 . . . . . . . divide by 3

Step-by-step explanation:

angle A + angle B + angle C = 180

x+x+37+x+67=180

3x+104=180

3x=180-104

3x=76

x=76÷3

x=25.3

angle A = 62.3

The function has exactly one x-intercept.

Option C is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Based on the table of values provided, we can see that as x increases, y also increases.

This means that the function is increasing function.

Furthermore,

Since the y-values are negative for small x-values and positive for large

x-values, there must be at least one x-intercept where the function changes sign.

So,

We can conclude that the function that generated the table of values has exactly one x-intercept.

Thus,

The function has exactly one x-intercept.

Answer:

Due to the higher z-score, Jane did better in class.

Step-by-step explanation:

Z-score:

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

Whoever's grade had the better z-score did better in class.

Mary's:

Mean of 85, standard deviation of 5, grade of 88. This means that [tex]\mu = 85, \sigma = 5, X = 88[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{88 - 85}{5}[/tex]

[tex]Z = 0.6[/tex]

Jane's

Mean of 80, standard deviation of 10, grade of 88. This means that [tex]\mu = 80, \sigma = 10, X = 88[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{88 - 80}{10}[/tex]

[tex]Z = 0.8[/tex]

Due to the higher z-score, Jane did better in class.

Answer:

c. The sampling distribution of the sample means can be assumed to be approximately normal because the distribution of the sample data is not skewed

Step-by-step explanation:

From the given data, we have;

The category of the sample = Retired individuals

The number of participants in the sample = 20

The duration of program = six-weeks

The improvement seen by most participants = Little to no improvement

The improvement seen by few participants = Drastic improvement

Therefore, given that the participants are randomly selected and the majority of the participants make the same observation of improvement in the time to walk a mile, we have that, the majority of the outcomes show little difference in walk times after the program, therefore, the distribution of the sample data is not skewed and can be assumed to be approximately normal

Complete question :

A study was designed to test whether applying metal tags is detrimental to a penguin. One variable examined is the survival rate 10 years after tagging. The scientists observed that 10 of the 50 metal tagged penguins survived, compared to 18 of the 50 electronic tagged penguins. Construct a 90% confidence interval for the difference in proportion surviving between the metal and electronic tagged penguins (). Let be the proportion of penguins with metal tags that survived and be the proportion of penguins with electronic tags that survived. Round your answers to three decimal places.

Answer:

(-0.305 ; - 0.015)

Step-by-step explanation:

Sample size, n1 = 50

x1 = 10

n2 = 50

x2 = 18

P1 = x1 / n1 = 10/50 = 0.2

P2 = x2 / n2 = 18 /50 = 0.36

1 - P1 = 0.8 ; 1 - P2 = 0.64

Zcritical at 90% = 1.645

Confidence interval :

(P1 - P2) ± Zcritical * standard error

Standard Error = sqrt[(p1(1-p1))/n1 + (p2(1-p2))/n2]

S.E = sqrt((0.2(0.8))/50 + 0.36(0.64))/50)

S.E = sqrt((0.0032 + 0.004608))

S. E = sqrt(0.007808)

S. E = 0.0883628

(0.2 - 0.36) ± (1.645 * 0.0883628)

-0.16 ± 0.145356806

Lower boundary = - 0.16 - 0.145356806 = −0.305356806

Upper boundary = - 0.16 + 0.145356806 = −0.014643194

Undefined

Step-by-step explanation:

To obtain the In(-0.375)

In x = log e x = y

The In is the natural logarithm of a number

To obtain the natural logarithm value of a given number using a calculator :

Simply press the In button followed by the value to obtain the direct value of the number x.

The In of any negative value gives an error output.

The In of x is only defined for values of x greater Than 0; that is ; X > 0

In of negative numbers is undefined

Answer:

X = 120

Step-by-step explanation:

here's your solution

=> we need to find the number whose 25%

is 30

=>. now , let the number be X

=> solve for X

=>. 25/100*X = 30

=> X = 30*100/25

=> X = 120
