The claim that the population mean is less than 125 (Option E) would

the interval tends to refute.

The 90% confidence interval for the population mean is 135 to 160. This means that if we were to repeat the process of taking samples from the same population and constructing a 90% confidence interval, we would expect 90% of the intervals to contain the true population mean.

With this in mind, let's consider each claim:

A. The interval does not rule out the possibility that the population mean is more than 110, as 110 is less than the lower bound of the interval.

B. The interval does not rule out the possibility that the population mean is less than 150, as 150 is greater than the upper bound of the interval.

C. The interval does not rule out the possibility that the population mean is between 140 and 150, as both of these values fall within the interval.

D. The interval does not rule out the possibility that the population mean is more than 140, as 140 is less than the upper bound of the interval.

E. The interval refutes the claim that the population mean is less than 125, as 125 is less than the lower bound of the interval.

Therefore, the answer is (E) The population mean is less than than 125.

Answer:

Frank can park 8.9 hours at the highest

Step-by-step explanation:

Here, we want to know the greatest amount of time that Frank can park given the amount he has to spend on parking.

From the question, we are told that he pays $2 for the hour and an extra $1 per additional hour.

Now, let the number of additional hour he is going to park be x. The bill for the additional hours will be ; $1 * x = $x

By adding this to the initial $2, we have the total $9.90

So, mathematically;

2 + x = 9.90

x = 9.9 -2

x = 7.9 hours

Now, the initial hour he parked is 1 hour + number of incremental hours = 1 + 7.9 = 8.9 hours

Answer:

see explanation

Step-by-step explanation:

Given

\(\frac{2}{5\sqrt{3} }\)

To rationalise the denominator, multiply the numerator/ denominator by \(\sqrt{3}\)

= \(\frac{2\sqrt{3} }{5\sqrt{3}(\sqrt{3}) }\)

= \(\frac{2\sqrt{3} }{15}\)

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

Given

\(\frac{\sqrt{5}+2 }{\sqrt{5}-2 }\)

Multiply the numerator/ denominator by the conjugate of the denominator.

The conjugate of \(\sqrt{5}\) - 2 is \(\sqrt{5}\) + 2 , then

= \(\frac{(\sqrt{5}+2)(\sqrt{5}+2) }{(\sqrt{5}-2)(\sqrt{5}+2) }\) ← expand numerator/denominator using FOIL

= \(\frac{5+4\sqrt{5}+4 }{5-4}\)

= \(\frac{9+4\sqrt{5} }{1}\)

= 9 + 4\(\sqrt{5}\)

Answer:

Genesis has 126 different outfits to choose from.

Step-by-step explanation:

To calculate the total number of different outfits Genesis can choose, we need to multiply the number of choices available for each article of clothing. So we have:

7 choices for pants

2 choices for t-shirts

3 choices for sweaters or hoodies

3 choices for shoes

To find the total number of outfits, we multiply the number of choices for each category:

7 x 2 x 3 x 3 = 126

Therefore, Genesis has 126 different outfits to choose from.

126 different combination does Genesis have to choose.

We have,

Pants = 7

T shirts = 2

Sweaters or Hoodies = 3

Shoes = 3

So, the number of different combination is

= C(7, 1) x C( 2, 1) x C(3, 1) x C(3, 1)

= 7 x 2 x 3 x 3

= 126 ways

Answer:

x=8

Step-by-step explanation:

The sum of interior angles of a triangle is 180°

9x+3+5x-2+11x-21=180°

25x-20=180

25x=180+20

25x=200°

x=200°/25

x=8

Answer:

8.

Step-by-step explanation:

Sum of the interior angles of a triangle is 180°;

hence;

(9x + 3)° + (5x - 2)° + (11x - 21)° = 180°

grouping like terms:

9x + 5x + 11x + 3 - 2 - 21 = 180

25x - 20 = 180

25x = 180 + 20

25x = 200 dividing both sides by 25;

x = 8

We need to find the general solution of the above PDE. Let's solve the above PDE by the method of characteristic. Let us first solve the PDE by using the method of characteristics.

The method of characteristics is a well-known method that provides a solution to the first-order partial differential equations. To use this method, we first need to find the characteristic curves of the given PDE. Thus, the characteristic curves are given by $x = t + c_1$.

Now, we need to eliminate $t$ from the above equations in order to obtain the general solution. By eliminating $t$, we get the general solution as:$$u(x,y) = f(2x - 3y) + 3(x - 2y)$$ where $f$ is an arbitrary function of one variable. Hence, the general solution of the PDE $u_{xx} - 2u_{xy} - 3u_{yy} = 0$ is given by the above equation. Thus, the main answer to the given question is $u(x,y) = f(2x - 3y) + 3(x - 2y)$. In order to find the general solution of the PDE $u_{xx} - 2u_{xy} - 3u_{yy} = 0$, we first used the method of characteristics. The method of characteristics is a well-known method that provides a solution to the first-order partial differential equations.

Step-by-step explanation:

Answer:

∠ O = 61°, ∠ N = 119°

Step-by-step explanation:

In a parallelogram

Consecutive angles are supplementary

Opposite angles are congruent, thus

x + 2x - 3 = 180

3x - 3 = 180 ( add 3 to both sides )

3x = 183 ( divide both sides by 3 )

x = 61°

Thus

∠ O = ∠ M = x = 61°

∠ N = ∠ P = 2x - 3 = 2(61) - 3 = 122 - 3 = 119°

x=2/3

Answer:

140,000

Step-by-step explanation:

We know that the number is 143,699.

We are asked to round to the nearest ten thousand, which is the number bolded:

143,699

This means we have to look at the number to the right of the 4, which is 3.  If this number is below "5", then we round down to get 140,000.  

If this number was (and it's NOT) above "5" or "5" itself, we would round up to 150,000.  

Since "3" is below "5", we would round down to 140,000.

(a) The probability of having at least one girl is 1 - 0.0625 = 0.9375 or 93.75%.

(b) The probability that all the children will be of the same gender is 0.0625 + 0.0625 = 0.125 or 12.5%.

The probability of having at least one girl can be calculated by finding the probability of having no girls and subtracting it from 1.

Assuming that the probability of having a boy or a girl is equal (0.5), the probability of having no girls is (0.5)^4 = 0.0625.

Therefore, the probability of having at least one girl is 1 - 0.0625 = 0.9375 or 93.75%.

(b) The probability that all the children will be of the same gender is 0.0625 + 0.0625 = 0.125 or 12.5%.

The probability that all the children will be of the same gender can be calculated by finding the probability of having all boys and adding it to the probability of having all girls.

The probability of having all boys is (0.5)^4 = 0.0625, and the probability of having all girls is also 0.0625.

Therefore, the probability that all the children will be of the same gender is 0.0625 + 0.0625 = 0.125 or 12.5%.

Current world population is 7.64 billion.

Number of people in developed nations :

\(n = \dfrac{7.64\times 17}{100}\\\\n=1.3\ billion\)

Now, per person in developed country eats 100 kg of meat .

So, 1.3 Billion people will eat :

\(M =1.3\times 100\ billion\ kg\\\\M=130\ billion\ kg\)

Therefore, meat consumed in the developed world in 1 year is 130 billion kg.

Hence, this is the required solution.

Based on the number of hours that the group of students gave as their responses, the median 10 hours can be found to be and the mean is 9.1 hours.

To find the median, you have to first order the responses from lowest to greatest and then pick the middle number.

The responses given were:

5, 10, 12, 10, 12, 6

When ordered we get:

5, 6, 10, 10, 12, 12

The middle number is found by the formula:

= (Middle number₁ + Middle number₂) / 2

= (10 + 10) / 2

= 10 hours

To find the mean, simple add up all the responses and then divide by the number of students:

= (5 + 6 + 10 + 10 + 12 + 12) / 6 student

= 55 / 6

= 9. 2 hours
