Answer:

Decision rule: Do not reject [tex]H_o[/tex]; we cannot conclude that the mean differs from zero

Step-by-step explanation:

From the given information:

The null hypothesis and alternative hypothesis is given as:

[tex]H_o: \mu = 0 \\ \\ H_1 : \mu \ne 0[/tex]

And the 99% confidence interval for the population mean [tex]\mu[/tex] is: [−3.79, 5.86]

The significance level ∝ = 1 - 0.99 = 0.01

We will notice that the 99% confidence interval for the population mean [tex]\mu[/tex] contains the null hypothesis mean value which is equal to zero.

Thus, we do not reject the null hypothesis at the significance level ∝ = 0.01

∴

Decision rule: Do not reject [tex]H_o[/tex]; we cannot conclude that the mean differs from zero

(15 * 10 ^ 5) binom 5*10^ 3 ) =300

(15 * 10 ^ 5)/(5 * 10 ^ 3)

(10 ^ 5)/(10 ^ 3) = 10 ^ 2

= (15 * 10 ^ 2)/5

: 15/5 = 3

= 3 * 10 ^ 2 = 3 * 10 ^ 2

3 * 10 ^ 2 = 300

The total money Paloma made = $117.25

In this question,

The price of Marigold(M) is $5.75.

The price of Daisy(D) is $6.25.

The price of Roses(R) is $2.50.

The price of Lilies(L) is $3.75

She sold 8 marigold flats and 10 daisy flats. An hour before closing, she sold 5 bunches of roses at half price and 2 bunches of lilies for 1/3 of the price.

Let s be the total money Paloma made

so we get an expression,

S = 8M + 10D + 5(R/2) + 2(L/3)

Now substitute the respective value

S = 8(5.75) + 10(6.25) + 5(2.5/2) + 2(3.75/3)

S = 46 + 62.5 + 6.25 + 2.5

S = $117.25

Therefore,  the total money Paloma made = $117.25

The maximum amount to donate to the summer camp fund is $2,250.

2. The equation that shows the maximum amount to donate is y = 4.5x.

An equation is a mathematical statement that two values are equal.

Using an equation, two mathematical expressions are stated to have equivalent values.

Equations are expressed using the equation symbol (=).

The expected number of theater goers = 500 persons

Admission charge per person = $10

Movie Theater's rental fee = $5.50

Ticket fee = $4.50 ($10 - $5.50)

Let y be the maximum amount to donate to the summer camp fund

Let x be = 500

y = (10 - 5.50)x

y = 4.5x

The required equation for the maximum amount to donate is y = 4.5x

y = 4.5 x 500

y = 2,250

Thus, the maximum amount to donate to the summer camp fund is $2,250.

The system of equations for find b, the number of black-and-white copies, and c, the number of color copies that the customer paid for at the print shop is,

⇒ b + c = 68

⇒ 0.08b + 0.15c = 6

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

Total amount paid = $6.00

Total copies = 68

Cost of black-and-white copy = $0.08

Cost of color copy = $0.15

Now, Let number of black-and-white copies = b

And, Number of color copies = c

Hence, The equation become;

b + c = 68

0.08b + 0.15c = 6

Therefore, The system of equations for find b, the number of black-and-white copies, and c, the number of color copies that the customer paid for at the print shop is,

Based on the table of Motor Vehicle Deaths, the Motor Vehicle Deaths per capita for Ohio is 0.00009 deaths per capita

When something is said to be per capita, it means that it is per person in the population.

The motor vehicle deaths per capita for Ohio can therefore be found by the formula:

= MV Deaths in Ohio / Ohio population

= 1,021 / 11.35 million

= 0.00009 deaths per capita

In conclusion, the Motor Vehicle Deaths per capita for Ohio is 0.00009 deaths per capita

Answer:

Given that,

A Galapagos tortoise can walk 1/5 mile in an hour.

We need to find time would it take the tortoise to walk 1/6 mile.

1/5 mile = 1 hour

1 mile = 1/1/5 = 5 hours

For 1/6 mile = 1/6 *5 = 0.834 hours

It will take 0.834 hours to walk 1/6 mile.

The statement is False.

Given that the SP is $0.60 per unit and the CP is $0.36 per unit.

So, profit per unit = $(0.60-0.36)

                            = $ 0.24

So, now we have to check whether 2500 units sales is required if we want a profit of $900.

To check we have to multiply the profit per unit with the sales,

      ⇒ 0.24 × 2500

      ⇒ $ 600

We can see clearly that we get a profit of $600 if we sale 2500 units. So, to make a profit of $900 we have to sale = [tex]\frac{900}{0.24}[/tex]

                                                                = 3750 units

Answer: The small side is 11, and the other two are 55, 55,

Step-by-step explanation:

So the perimeter adds up to 121 inches.

we know that two of the sides are 5x the 3rd side while being congruent.

11 times 5=55. 55 times 2=110. 110+11=121

Answer:

The third side is 11 inches

the 2 equal sides are 55 inches each side.

Step-by-step explanation:

X + 2(5x) = 121

x + 10x = 121

11x = 121

x = 121/11

x = 11

Answer:

x = 13

y = -5

Step-by-step explanation:

Let x = the first number

Let y = the second number

x + 2y = 3                            2x + y = 21

You have two unknowns, so you need to equations to solve.

Solve the first equation for x:

x + 2y = 3

x = -2y + 3  Substitute this in for x in the second equation.

2x + y = 21

2(-2y + 3) + y = 21  Distribute the 2

-4y + 6 +y = 21 combine the y's

-3y = 15 Divide both sides by -3

y = -5

Plug -5 back in for either equation

x + 2y = 3

x + 2(-5) = 3

x -10 =3

x = 13
