Answer:

since p value(0.001091 ) is less than less than alpha(0.05)

null hypothesis H₀ is rejected.

Hence, we conclude that there is a relationship between personality and disorder.

Step-by-step explanation:

Given the data in the question;

              non-heart disease          heart disease         total

TypeA            32                                 18                         50

TypeB           128                                22                        150

total               160                                40

level of significance ∝ = 0.05

H₀ : There is no relationship between personality and disorder

H₁ : There is a relationship between personality and disorder

so

the computational table for x²

E₁ = 50×160 / 200 = 40

O                E               O-E              (O-E)²                  (O-E)² /E

32              40              -8                   64                          1.6

18               10                8                   64                          6.4

128             120              8                   64                         0.5333

22              30              -8                   64                         2.133

∑                                                                                       10.667

so

X² = ∑( (O-E)² /E ) = 10.667

The contingency table is 2×2, since there are 2 rows and 2 columns

df = (2-1)(2-1) = 1  

P Value from Chi-Square Calculator    

Chi-square score: 10.667

DF : 1

p-value = 0.001091

since p value(0.001091 ) is less than less than alpha(0.05)

null hypothesis H₀ is rejected.

Hence, we conclude that there is a relationship between personality and disorder.

  y' = -sin(x)

Step-by-step explanation:

Your table of derivatives of trig functions tells you the derivative of the cosine is the opposite of the sine.

  dy/dx = -sin(x)

Answer:

The formula for density (ρ) is:

Density (ρ) = Mass (m) / Volume (V)

Step-by-step explanation:

Where:

-254 = -10k -2 -8k

or, -254+2 = -18k

or, -252 = -18k

or, k = -252/-18 = 14

Answer is 14.

Answer: k = 14

Step-by-step explanation:

First combine like terms: -254 = -18k - 2

Next use Addition Property of Equality (add 2 to both sides to cancel the 2 on the right side of the equation) : -252 = -18k

Last, use Division Property of Equality (divide both sides by -18 to get k by itself): 14 = k

*when solving an equation like this, you are always trying to get k by itself, and whatever you do to one side, do it to the other to keep them equal

Answer:

$25

Step-by-step explanation:

De la pregunta anterior, se nos da la siguiente información

Yo TENÍA $ 5

Mi mamá me dió $ 10

Mi papá me dió $ 30

Mi tío y mi tía me dieron $ 100

Yo TENÍA otros $ 20

Si miras arriba, notarás que la palabra TENÍA está en mayúscula.

Esto se debe a que para resolver esta pregunta correctamente, tenemos que concentrarnos o prestar atención a los tiempos verbales del inglés que se usan al hacer la pregunta.

La pregunta dice: ¿Cuánto tenía?

Esto significa que la pregunta anterior es sobre cuánto tenía en el pasado antes de que sus padres, tío y tía le dieran dinero.

Por lo tanto, la cantidad de dinero que tenía

= $20 + $5

= $ 25

The total amount I have altogether will be $165

In order to get the total amount that you have, we will add all the cash you were given and the ones you have altogether.

Amount initially owned = $5

Amount given by relatives = $10 + $30 + $100

Amount given by relatives = $140

If he has another $20

Total amount I have = $5 +$140 + $20

Hence the total amount I have altogether will be $165

Answer:

x + 3y = -15

Step-by-step explanation:

There are 2 ways to find this equation:

The first way:  We have: y = ax + b (this is the line, right?)

The line is through the point (-6, -3) so we have:

-3 = (-6)a + b      (1)

The line is also through the point (-9, -2) so we have:

-2 = (-9)a + b.       (2)

From (1) and (2) we get a equals -1/3, b equals -5. Then:

\(y=-\frac{1}{3} x - 5\)

<=> \(x + 3y=-15\)

The second way:

Let A(-6, -3) and B(-9, -2), then AB = (-3, 1).

=> The normal vector of this line is n = (1, 3).

The line that is through the points A(-6, -3) and B(-9, -2), and has the normal vector n=(1, 3) has the equation:

\(1(x+6) +3(y+3)=0\\x+3y +15=0\\x+3y=-15\)

Answer:

-3x+31

Answer:

≤ 4.3 gigabytes

Step-by-step explanation:

Flat fee + cost for x gigabytes = her budget

47 + 5 * x ≤ 68.50

5x = 68.50 - 47 ≤ 21.50

x ≤ 21.50/5 = 4.3 gigabytes

Micaela can use approximately 4.3 gigabytes of data while staying within her budget of $68.50 per month.

Let, "x" to represent the number of gigabytes of data Micaela can use while staying within her budget.

The total cost can be calculated by adding the flat cost of $47 to the cost based on the gigabytes used ($5 per gigabyte):

Total Cost = Flat Cost + (Cost per Gigabyte * Number of Gigabytes)

Given that Micaela wants to keep her bill at $68.50 per month, we can set up the equation:

68.50 = 47 + 5x

Now, solve for x:

68.50 - 47 = 5x

21.50 = 5x

Divide both sides by 5:

x = 21.50 / 5

x = 4.3

So, Micaela can use approximately 4.3 gigabytes of data while staying within her budget of $68.50 per month.

Confidence interval for the population mean time σ for computer repairs is [98.05 , 89.850].

What is confidence interval?

A confidence interval, in statistics, refers to the chance that a population parameter can fall between a collection of values for an exact proportion of times.

Main body:

According to question:

N = 110

X bar = 93.9 minutes

σ = 16.9 minutes

value for 99% confidence interval = 2.576

C.I. = x bar ± z*s/√n

C.I. = 93.9 ± 2.576 *16.9 /√110

C.I. = 93.9 ± 4.150

C.I. = [98.05 , 89.850]

Hence , confidence interval for the population mean time σ for computer repairs is [98.05 , 89.850].

Answer:

Step-by-step explanation:

Let h(x) = y

The exponentail function is of the form :

\(y = ab^x\)

We have :

\(y_{_1} = ab^{x_{_1}}\\y_{_2} = ab^{x_{_2}}\\\\\implies \frac{y_{_1}}{y_{_2}} = \frac{ab^{x_{1}}}{ab^{x_{2}}} \\\\\implies \frac{y_{_1}}{y_{_2}} = \frac{b^{x_{1}}}{b^{x_{2}}} \\\\\implies \frac{y_{_1}}{y_{_2}} = b^{(x_1-x_2)}\)

Given points : (4, 9) and (5, 34.2)

We have:

\(\frac{34.2}{9} = b^{(5-4)}\\\\\implies 3.8 = b\)

Writing the equation with x, y and b:

\(y = ab^x\\\\\implies 9 = a(3.8^4)\\\\a = \frac{9}{3.8^4} \\\\a = 0.043\)

a = 0.043

b = 3.8

When x = 6, y will be:

\(y = (0.043)(3.8^6)\\\\y = 128.47\)

This is not the y value in the question y = 59.4

Therefore (6, 59.4) does not lie on the graph h(x)
