Answer:

With alpha 0.95 and 8 degrees of freedom χ²= 2.73

And with alpha 0.05 and 8 degrees of freedom χ²=15.51

Step-by-step explanation:

The significance level ∝ = 1- 0.9 = 0.1

But we need the area of the middle so we divide this significance level with 2

so that we get exactly the middle area .

Dividing 0.1/2= 0.05

So we will have two values for chi square

One with  0.9 + 0.05 = 0.95 alpha and one with 0.05 alpha . This is because the chi square is right tailed.

So with alpha 0.95 and 8 degrees of freedom χ²= 2.73

And with alpha 0.05 and 8 degrees of freedom χ²=15.51

This can be shown with a graph.

Step-by-step explanation:

Under a half turn about the origin

a point (x, y ) → (- x, - y ) , thus

(3, 0 ) → (- 3, 0 )

(3, 4 ) → (- 3, - 4 )

(- 1, - 4 ) → (1, 4 )

(r, s ) → (- r, - s )

The coordinates of the image point under a half-turn about the origin(3, 0 ) is (- 3, 0 ), (3, 4 ) is (- 3, - 4 ), (- 1, - 4 )  is (1, 4 ), (r, s ) is (- r, - s ).

The mirror image of a point in coordinate geometry is the image formed with respect to the x-axis, y-axis, or origin.

A point (x, y ) has image point (- x, - y )

Thus,

The coordinates of the image point under a half-turn about the origin(3, 0 ) is (- 3, 0 )

The coordinates of the image point under a half-turn about the origin(3, 4 ) is (- 3, - 4 )

The coordinates of the image point under a half-turn about the origin(- 1, - 4 )  is (1, 4 )

The coordinates of the image point under a half-turn about the origin(r, s ) is (- r, - s )

Less cash received                ??.??

Total                                        62.23

We need to find the less cash received.

A deposit slip is a bank form where the customer fills in the required date such as the date, the depositor's name, the depositor's account number, and the deposit amounts.

Find the subtotal.

= Cash included coins + check 1 + check 2 + check 3

= 15.00 + 62.44 + 27.83 + 45.75

= 151.02

Find the less cash received.

We have,

Total = 62.23

Total = Subtotal - less cash received

62.23 = 151.02 - less cash received

less cash received:

= 151.02 - 62.23

= 88.79

Thus, the cash the person who filled this deposit slip received is $88.79.

Answer:

3kg = 3000 gm

Step-by-step explanation:

we use this formula

m1x (distance of m1 )= m2 x( distance of m2)

* the distance far from the triangle*

m1 =6 kg

d1 = 3m

m2 = ê (kg )

d2 = 600 cm = 6 m

m1 d1 = m2 d2

6 x 3 = ê 6

ê = 3 kg

mass = 3kg = 3000 gram

#

To make the scale balance, the weight must be added is 3000g.

"A balanced equation is an equation where both sides are equal to the same amount. The answer to the expression on the left side of the equals sign (=) should be equal to the value on the right side of the equals sign".

For the given situation,

From the diagram shown, the distance on both sides of the fulcrum (the triangle) must be the same to make the scale balance.

We know that

1 kg = 1000 g

1 m = 100 cm

Let the unknown quantity be 'x'

To write a balanced equation, units should be the same on both sides.

6 kg = 6000 g

3 m = 300 cm.

The equation is represented as

[tex]6000[/tex] × [tex]300 = x[/tex] × [tex]600[/tex]

⇒ [tex]x = \frac{(6000)(300)}{600}[/tex]

⇒ [tex]x=3000[/tex]

Hence we can conclude that to make the scale balance, the weight must be added is 3000g.

Answer:

30.4 minutes

Step-by-step explanation:

The tank already has 240L in it, so we need to fill 1000 - 240 = 760L of water.

Since the pump pumps 25L per minute, we can find how many minutes it takes to pump 760L.

760 / 25 = 30.4 minutes.

It will take 30.4 minutes to fill the tank completely.

Two or more expressions with an equal sign are defined as an equation.

Given that, The 1000 L tank contains 240 L of water, therefore, the free space in the tank is :

1000-240

= 760 L

The pump fills the tank at a rate of 25 L per minute.

Therefore, it can be represented as:

25 L = 1 minute

1 L = (1/25) minutes

760 L = (1/25)×760 minutes

760 L = 30.4 minutes.

Hence, it will take 30.4 minutes to fill the tank completely.

Answer and Step-by-step explanation: Marginal Benefit is the maximum a person is willing to pay for an additional good or service. It can be calculated as:

[tex]marginal=\frac{Change total benefit}{Change quantity}[/tex]

For each cup of coffee:

For the first cup, benefit is $8;

For the second:

[tex]marginal=\frac{14-8}{2-1}[/tex]

marginal = 6

For the third:

[tex]marginal=\frac{18-14}{3-2}[/tex]

marginal = 4

For the fourth:

[tex]marginal=\frac{20-18}{4-3}[/tex]

marginal = 2

For the fifth:

[tex]marginal=\frac{21-20}{5-4}[/tex]

marginal = 1

The cost of the coffe is $3, so comparing benefit and cost, Neal should consume 4 cups of cofee per day.

Given :

A grocery store charges 1.25 $ for every 3/4 pound of chocolate purchased.

To Find :

How much will the store charge a customer who purchases 9 pounds of chocolate .

Solution :

3/4 pound store charges 1.25 $ .

Let , cost of 1 pound is x .

So ,

[tex]\dfrac{3x}{4}=1.25\\\\x=\dfrac{1.25\times 4}{3}\\\\x=1.67\ \$[/tex]

Now , cost of 9 pounds chocolate is :

[tex]C=9\times 1.67\ \$\\\\C=15.03\ \$[/tex]

Hence , this is the required solution .

Answer:

Step-by-step explanation:

Given the function  j(x) = 11.6[tex]e^x[/tex] and k(x) = [tex]ln \dfrac{x}{11.6}[/tex], to show that both equality functions are true, all we need to show is that both  j(k(x)) and k(j(x)) equal x,

For j(k(x));

j(k(x)) = j[(ln x/11.6)]

j[(ln (x/11.6)] = 11.6e^{ln (x/11.6)}

j[(ln x/11.6)] = 11.6(x/11.6) (exponential function will cancel out the natural logarithm)

j[(ln x/11.6)] = 11.6 * x/11.6

j[(ln x/11.6)] = x

Hence j[k(x)] = x

Similarly for k[j(x)];

k[j(x)] = k[11.6e^x]

k[11.6e^x] = ln (11.6e^x/11.6)

k[11.6e^x]  = ln(e^x)

exponential function will cancel out the natural logarithm leaving x

k[11.6e^x]  = x

Hence k[j(x)] = x

From the calculations above, it can be seen that j[k(x)] =  k[j(x)]  = x, this shows that the functions j(x) = 11.6[tex]e^x[/tex] and k(x) = [tex]ln \dfrac{x}{11.6}[/tex] are inverse functions.

A Chi-square test for goodness of fit will be used to determine whether the types of cookies purchased by the customers depends on where the scouts sell them.

The hypothesis can be defined as:

H₀: The observed frequencies are same as the expected frequencies.

Hₐ: The observed frequencies are not same as the expected frequencies.

The test statistic is given as follows:

[tex]\chi^{2}=\sum\limits^{n}_{i=1}\frac{(O_{i}-E_{i})^{2}}{E_{i}}[/tex]

The formula to compute the expected frequency is:

[tex]E_{i}=\frac{i^{th}\ \text{Row Total}\times i^{th}\ \text{Column Total}}{N}[/tex]

Consider the Excel output for the expected frequency values.

The Chi-square test statistic value is:

[tex]\chi^{2}=\sum\limits^{n}_{i=1}\frac{(O_{i}-E_{i})^{2}}{E_{i}}=56.788[/tex]

The degrees of freedom is:

df = (r - 1)(c - 1)

   = (3 - 1)(5 - 1)

   = 2 × 4

   = 8

The p-value is:

[tex]P(\chi^{2}_{8}>56.788)<0.00001[/tex]

*Use a Chi-square table.

The p-value of the test is very small.

The null hypothesis will be rejected at 1% level of significance.

Conclusion:

There is enough evidence to support the claim that the types of cookies purchased by the customers depends on where the scouts sell them.
