The null hypothesis is  \(H_o : \mu \ge 8300\)

The  alternative hypothesis is  \(H_a : \mu < 8300\)

B

  \(t = -3.34\)

C

 \(p-value = P(t< -3.34) = 0.00041889\)

D

 reject the null hypothesis  

Step-by-step explanation:

From the question we are told that

    The population mean is  \(\mu = 8300\)

    The sample mean is \(\ = x = 8000\)

     The  standard deviation is \(s = 440\)

      The sample size is  \(n = 24\)

       The  level of significance is  \(\alpha = 0.01\)

The null hypothesis is  \(H_o : \mu \ge 8300\)

The  alternative hypothesis is  \(H_a : \mu < 8300\)

 The  test statistic is mathematically evaluated as

                     \(t = \frac{\= x - \mu }{ \frac{s}{\sqrt{n} } }\)

=>                  \(t = \frac{8000- 8300 }{ \frac{440}{\sqrt{24} } }\)

=>                    \(t = -3.34\)

The p-value is obtained from the z -table ( reference calculator dot net ) , the value is

         \(p-value = P(t< -3.34) = 0.00041889\)

Looking at the values of  \(p-value and \ \alpha\) we see that  \(p-value < \alpha\) Hence we reject the null hypothesis  

2x² - 6x = -7 equation has  imaginary solutions

To determine if an equation has imaginary solutions, we can examine the discriminant of the quadratic equation

x² + 3x - 5 = 0

a = 1, b = 3, c = -5

Discriminant = (3)² - 4(1)(-5) = 9 + 20 = 29

The equation has two real solutions

x⁴ - 5x ^ 2 + 3 = 0

This equation is a quartic equation, not a quadratic equation. Quartic equations can have both real and imaginary solutions

2x² - 6x = -7

2x^2 - 6x + 7 = 0

a = 2, b = -6, c = 7

Discriminant = (-6)²- 4(2)(7) = 36 - 56 = -20

Since the discriminant (-20) is negative, the equation has two complex (imaginary) solutions.

-3x² = -5

Dividing both sides by -3, we get:

x²= 5

a = 1, b = 0, c = -5

Discriminant = 0² - 4(1)(-5) = 20

The equation has two real solutions.

Hence, 2x² - 6x = -7 equation has imaginary solutions

Answer:

Below

Step-by-step explanation:

x^2 + 32 + 116 = 12x         1st intermediate step: put everything on one side

x^2 -12x + 148 = 0      2nd intermediate step : re-arrange with constant on R

In order to show that △ ABC ≅ △ DEF by SAS congruence, we need the sides of triangles ABC and DEF with the angle between the respective sides.

Triangle congruence: Two triangles are said to be congruent if all three of their corresponding sides and all three of their corresponding angles have the same measurements. Slide, twist, flip, and turn these triangles to create an identical appearance. They are in alignment with one another when moved. "" is the congruence symbol. When two figures are comparable to one another in terms of their size and shape, this is what mathematicians mean by congruence. In essence, there are four congruence principles that demonstrate if two triangles are congruent. However, locating all six dimensions is essential. As a result, the congruence of triangles can be assessed using just three of the six variables.

The thermometer reading would be 73.48°C.

The boiling point of water is generally considered to be 100°C. According to the given information, the temperature of the liquid in the thermometer is 26.52°C lower than the boiling point of water. Therefore, to find the thermometer reading, we subtract 26.52 from 100.

100 - 26.52 = 73.48

Hence, the thermometer reading would be 73.48°C.

In this scenario, we are assuming that the thermometer is calibrated to measure temperature in Celsius. The boiling point of water at standard atmospheric pressure is 100°C, and the given information states that the liquid in the thermometer is 26.52°C lower than the boiling point.

By subtracting 26.52 from 100, we obtain a reading of 73.48°C.

Thermometers work by utilizing the principle that certain substances, such as mercury or alcohol, expand or contract with changes in temperature. The expansion or contraction is measured using a scale, which is marked with various temperature values.

In this case, the thermometer is calibrated in Celsius, so we refer to the Celsius scale. By subtracting 26.52 from 100, we find the temperature at which the liquid in the thermometer is settled, which is 73.48°C.

Answer: Andre should buy Car 2. Brainliest?

Step-by-step explanation:

To compare the gas mileage of the two cars, we need to find out how many miles each car can travel per gallon of gas.

For Car 1: y = 25x

This means that for every gallon of gas used (x), the car can travel 25 times that amount in miles (y). So, the gas mileage for Car 1 is 25 miles per gallon (mpg).

For Car 2: we can calculate the miles per gallon by dividing the total miles traveled by the number of gallons of gas used:

For 2 gallons of gas, the car can travel 60 miles. So, the gas mileage is 30 mpg (60 miles ÷ 2 gallons).

For 5 gallons of gas, the car can travel 150 miles. So, the gas mileage is 30 mpg (150 miles ÷ 5 gallons).

For 7 gallons of gas, the car can travel 210 miles. So, the gas mileage is 30 mpg (210 miles ÷ 7 gallons).

For 8 gallons of gas, the car can travel 240 miles. So, the gas mileage is 30 mpg (240 miles ÷ 8 gallons).

For 11 gallons of gas, the car can travel 330 miles. So, the gas mileage is 30 mpg (330 miles ÷ 11 gallons).

Therefore, Car 2 has a consistent gas mileage of 30 mpg.

From the above calculations, we can see that Car 2 has a better gas mileage compared to Car 1. Car 2 can travel 30 miles on a gallon of gas, while Car 1 can only travel 25 miles on a gallon of gas.

Therefore, Andre should buy Car 2 if he wants to get the best gas mileage. Car 2 can travel 5 more miles per gallon than Car 1.

This best explains why the best decision alternative is the one with the highest preference probability:

This corresponds to the alternative with the highest probability of getting a good outcome.

Step-by-step explanation:

In making a decision under probability, it is the decision maker's preference probability that sways the choice.  For the decision maker, therefore, the probability of getting a good outcome is always the preferred probability.  So, any alternative that yields a good outcome for the decision maker is always chosen.  And this usually corresponds to the alternative with the highest preference probability.

Step-by-step explanation:

The ratio of the number of corn tortillas to flour tortillas is 3:4. So this means there are at least 3 corn tortillas and 4 flour tortillas.

We need to add 3 and 4 to see the simplified total of tortillas. 3+4=7.

There is a total of 7 tortillas regardless of their type.

Now we just need to compare this with the number they already gave us for flour tortillas, which is 4.

Explanation:

We have five slots to fill, which I'll label A through E.

There are,

Each time we fill up a slot, we count down by 1.

This gives 14*13*12*11*10 = 240,240 different permutations. If order mattered, then this would be the answer.

However, order doesn't matter on a committee without rankings. Each member has the same rank as any other.

Within any group of 5 people, there are 5! = 5*4*3*2*1 = 120 ways to arrange them. This means we divide that 240,240 figure by 120 to find the number of combinations.

There are (240,240)/(120) = 2002 different combinations.

---------------------------------------

Here's how we could have done the problem using the nCr combination formula.

Plug in n = 14 and r = 5.

n C r = (n!)/(r!(n-r)!)

14 C 5 = (14!)/(5!*(14-5)!)

14 C 5 = (14!)/(5!*9!)

14 C 5 = (14*13*12*11*10*9!)/(5!*9!)

14 C 5 = (14*13*12*11*10)/(5!)

14 C 5 = (14*13*12*11*10)/(5*4*3*2*1)

14 C 5 = (240240)/(120)

14 C 5 = 2002

Answer: I think A 1,220 (I'm not sure)

Step-by-step explanation:

the aswer is A.1,220 si think si correct.

(i). His monthly basic salary is Rs 79,200.

(ii) His taxable income is Rs 1,02,480.​

(i) The monthly basic salary of the married COAS General is given as Rs 79,200, with an additional Rs 2,000 as a dearness allowance.

Total salary = Basic salary + Dearness allowance

Total salary = Rs 79,200 + Rs 2,000

Total salary = Rs 81,200

So his monthly basic salary is Rs 79,200.

(ii)

Total income = Basic salary + Dearness allowance + Dashain allowance

Total income = Rs 79,200 + Rs 2,000 + Rs 79,200

Total income = Rs 1,60,400

From this, we subtract his EPF contribution and life insurance premium:

Taxable income = Total income - EPF contribution - Life insurance premium

Taxable income = Rs 1,60,400 - 10% of Rs 79,200 - Rs 50,000

Taxable income = Rs 1,60,400 - Rs 7,920 - Rs 50,000

Taxable income = Rs 1,02,480
