The experimental probability of landing on a number greater than 4 is 0.25 or 25%.

To find this probability, we need to determine the number of successful outcomes (landing on a number greater than 4) and divide that by the total number of trials (60).

The successful outcomes are 5 and 6, with a frequency of 10 and 8 respectively. To add these two frequencies together, we can use 10 + 8 = 18.

So, the experimental probability is 18/60 = 0.3 or 25%.

It's important to note that experimental probability is based on the outcomes of an experiment or a sample and it may not be the same as a theoretical probability which is based on the ratio of favorable outcomes to the total number of outcomes in a theoretical model.

A baker uses 5.5 Ibs of flour daily

The baker's recipe for a loaf of bread calls for 12 oz of flour. If he uses all of his flour to make loaves of bread, how many loaves can he bake in seven days?

Answer:

51.3 loaves of bread

Step-by-step explanation:

Converting 5.5 Ibs to oz (ounces)

1 Ibs =>12 oz

5.5 Ibs => x

Cross Multiply

12 × 5.5 => 88 oz

1 loaf of bread =>12 oz

Hence, in 1 day

12 oz =>1 loaf of bread

88 oz => x

x =>88 oz/ 12 oz

x => 7.3333333333 loaves of bread

Hence, he can make 7.3333333333 loaves of bread in 1 day

Hence, in 7 days

1 day => 7.3333333333 loaves

7 days => x

x => 7 × 7.3333333333 loaves

x => 51.333333333 loaves of bread

Approximately => 51.3 loaves of bread

Answer:

cos(a + b) = \(\frac{1}{12}(1-2\sqrt{30})\)

Step-by-step explanation:

cos(a + b) = cos(a).cos(b) - sin(a).sin(b) [Identity]

cos(a) = \(-\frac{1}{3}\)

cos(b) = \(-\frac{1}{4}\)

Since, terminal side of angle 'a' lies in quadrant 3, sine of angle 'a' will be negative.

sin(a) = \(-\sqrt{1-(-\frac{1}{3})^2}\) [Since, sin(a) = \(\sqrt{(1-\text{cos}^2a)}\)]

         = \(-\sqrt{\frac{8}{9}}\)

         = \(-\frac{2\sqrt{2}}{3}\)

Similarly, terminal side of angle 'b' lies in quadrant 2, sine of angle 'b' will be  negative.

sin(b) = \(-\sqrt{1-(-\frac{1}{4})^2}\)

         = \(-\sqrt{\frac{15}{16}}\)

         = \(-\frac{\sqrt{15}}{4}\)

By substituting these values in the identity,

cos(a + b) = \((-\frac{1}{3})(-\frac{1}{4})-(-\frac{2\sqrt{2}}{3})(-\frac{\sqrt{15}}{4})\)

                = \(\frac{1}{12}-\frac{\sqrt{120}}{12}\)

                = \(\frac{1}{12}(1-\sqrt{120})\)

                = \(\frac{1}{12}(1-2\sqrt{30})\)

Therefore, cos(a + b) = \(\frac{1}{12}(1-2\sqrt{30})\)

Answer:

80% of the flour is left.

Answer:

I hope may answer is correct! I am sorry if it is not!

The chef used 800g out of a 5kg bag of flour, so the amount of flour left is 5,000g - 800g = 4,200g. To find the percentage of flour left, divide the amount of flour left by the total amount of flour and multiply by 100: (4,200g / 5,000g) * 100 = 84%. So 84% of the flour is left.

Step-by-step explanation:

the 2nd and 4th answers look good.  the 1st answer is correct as well.

To solve this look at the x axis and y axis,  the x axis is in inches, the y axis is in pounds.  So you know that as the distance increase per inch,  the force in pounds is increasing too.  

so the force applied is going up,   0.73 pounds , for each inch of travel ( or stretch) of the spring.  

The stopping distance for a car traveling at 55 mph is 60,500 feet.

The equation to solve this problem would look like the following

s = v²/k

The stopping distance s will increase (varies directly) as the velocity increases.

Putting in the values we know

45 = 30²/k

⇒ k = 45/900

⇒ k = 0.05

Now,

at 55 mph we would have

    s = 55²/0.05

⇒ s = 3025/0.05

⇒ s = 60,500

s = 60,500 feet to stop

Sampling Error

Step-by-step explanation:

We are told that the phenomenon is the naturally occurring difference between a sample statistic and the corresponding population parameter.

Now, it's sampling error because sampling error is simply defined as a deviation or difference in a sampled value as against the true population value due to the fact the sample is not a true representative of the population.

This is also similar to the definition given in the question.

Thus, it's sampling error!

For a taxable income of $1,80,900, the effective tax rate is 21.11%.

Marginal tax is the tax rate applied to an individual’s last dollar of income. It is the additional tax that must be paid on any additional income earned. In other words, it is the tax rate that applies to an individual’s income after all deductions. For example, if an individual’s income is $50,000 and the marginal tax rate is 25%, then the individual must pay an additional $12,500 in taxes on top of the $25,000 in taxes already paid on their $50,000 income.

Marginal tax rates are progressive, meaning that as an individual’s income increases, the marginal tax rate will increase as well. The marginal tax rate is important to understand because it helps individuals determine how much additional income they will need to earn in order to make up for the taxes they will have to pay on that income. It is also important to understand how marginal tax rates can affect tax planning strategies.

To determine the effective tax rate for a taxable income of $180,900, calculate the sum of the marginal tax rates for each tax bracket that the $180,900 falls into. The taxable income of $180,900 is greater than $89,075 and less than $170,050. The marginal tax rates for these two tax brackets are 22% and 24%, respectively. The sum of the marginal tax rates is 46%. Divide the sum by the taxable income of $180,900 to get the effective tax rate of 21.11%. Round the final answer to the nearest hundredth to get 21.11%.

After 4 hours of discharging, the volume left in the tank would be 500 liters. The correct option is C.

Initially, the tank has a water capacity of 1500 liters.

After three hours of discharging, half of the water is discharged, which means 1500/2 = 750 liters have been removed from the tank.

To find the volume left after 4 hours of discharging, we need to subtract the additional amount discharged in the fourth hour.

Since the discharge rate remains the same, we can calculate the amount discharged in one hour as 750/3 = 250 liters.

Therefore, in the fourth hour, 250 liters would be discharged. Subtracting this from the remaining water after three hours (750 liters), we get 750 - 250 = 500 liters.

Therefore, the correct answer is c. 500 liters.

The interval of convergence is (-9/2, -3/2) and the radius of convergence is 3.

To determine the radius and interval of convergence for the series, we can use the ratio test.

The ratio test states that if we have a series ∑(aₙ), and if the limit as n approaches infinity of |aₙ₊₁ / aₙ| is L, then the series converges if L < 1 and diverges if L > 1.

Let's apply the ratio test to the given series:

aₙ = (2/3)ⁿ * (x + 3)ⁿ

To apply the ratio test, we calculate the ratio of successive terms:

|aₙ₊₁ / aₙ| = |[(2/3)ⁿ⁺¹ * (x + 3)ⁿ⁺¹] / [(2/3)ⁿ * (x + 3)ⁿ]|

= |(2/3) * (x + 3)|

Now, let's determine the limit as n approaches infinity of the ratio:

lim(n→∞) |(2/3) * (x + 3)| = |2/3| * |x + 3|

For the series to converge, this limit should be less than 1:

|2/3| * |x + 3| < 1

Simplifying the inequality:

2/3 * |x + 3| < 1

|2x + 6| < 3

-3 < 2x + 6 < 3

-9 < 2x < -3

-9/2 < x < -3/2

Therefore, the interval of convergence is (-9/2, -3/2).

To determine the radius of convergence, we take half the length of the interval:

radius of convergence = (|-9/2| + |-3/2|) / 2

= (9/2 + 3/2) / 2

= 12/4

= 3

Hence, the radius of convergence is 3.

Step-by-step explanation:

Han's retirement account earns $247,163.25 in simple interest.

To find the simplest interest, we need to use the formula:

Simple Interest = Principal × Rate × Time

In this case, the Principal is $410,000 and the Rate is $15,785 per year. We don't know the time period, but we can solve for it using the formula:

Time = Simple Interest ÷ (Principal × Rate)

Plugging in the values, we get:

Time = $15,785 ÷ ($410,000 × 1) = 0.0385 years

Therefore, the simplest interest is:

Simple Interest = $410,000 × $15,785 × 0.0385 = $247,163.25

So Han's retirement account earns $247,163.25 in simple interest.
