Bobby and Garnetta thought of four consecutive odd intergers such as five times the sum of the first and the third was 22 greater than the product of 8 and the sum of the second and the fourth. Find the numbers.

Since the time is 0.24 hour. Yes, it takes less than a quarter of an hour to fill the container

Given: A container is a hemisphere of radius 30cm

Sand fills the container at a rate of 4000 cm³ per minute

A hemisphere is half a sphere. Thus:

The volume of a hemisphere = 1/2 × 4/3 πr³ = 2/3 πr³

The volume of a hemisphere = 2/3 × π × 30 = 56548.67 cm³

Rate = Volume / Time

Time = Volume/Rate

Time =  56548.67 /4000 = 14.14 minutes

In hours: Time = 14.14/60 = 0.24 hour

The top 18 percent of scores fall within two standard deviations of the mean.

Publicly recognized refers to something that is well-known or acknowledged by the public or by a large segment of the population. This could include a famous person, a popular business, or an important event or achievement. Public recognition is often seen as an indicator of success, as it shows that the person or thing being recognized has achieved something noteworthy or has had a positive influence on the public. Examples of publicly recognized things include awards, honors, and other achievements.

Assuming a normal distribution, a student needs to score at least two standard deviations above the mean to be publicly recognized. This is because the top 18 percent of scores fall within two standard deviations of the mean. This can be expressed mathematically as:
P(x > μ + 2σ) = 0.18

Compound interest refers to the interest added to a loan or deposit. It is the concept that we employ every day on a regular basis. Amounts are based on both the principal amount and Rate of interest when calculating compound interest. 

The formula used for

P = Principal amount

r = Rate of interest  

n = Number of compounds in a year  

t = Time period in years

And the formula for

Here we have

Principal amount = 1700,

Rate of interest = 2% = 2/100  = 0.02 on decimals  

Given that compound interest gained = $ 500

Number of compounds = 4 times

Let a be the time period

By the given formula,

Amount, A = 1700(1+0.02/4)^4t  

= 1700(1+0.005)^4t    

= 1700 (1.005)^4t  

Compound interest = 1700 (1.005)^4t - 1700

From the given data,

Compound interest = $ 500

=> 1700 (1.005)^4t - 1700 = 500

=> 1700 (1.005)^4t = 2200

=> (1.005)^4t = 1.294

Take logs on both sides

=> log (1.005)^4t = log 1.294

=> 4t log (1.005) = log (1.294)

=> 4t = log(1.294)/log(1.005)

=> 4t = 0.111934276/ 0.00216606176      

[ Use calculator for log(1.294) and log(1.005) ]

Answer:

x = 8

y = 2

Step-by-step explanation:

To find the equation of a line that is parallel to y=−7+4x and passes through the point (-2,-1), we can use the point-slope form of the equation of a line. The point-slope form of the equation of a line is:

y - y1 = m(x - x1)

Where (x1, y1) is a point on the line, and m is the slope of the line.

Since the given line y=−7+4x is in slope-intercept form, we can find the slope by taking the coefficient of x, which is 4. This means that the slope of the line is 4.

We can then use the point-slope form to find the equation of the line that is parallel to y=−7+4x and passes through the point (-2,-1). Plugging in the values for the slope and the point, we get:

y - (-1) = 4(x - (-2))

Simplifying this expression gives us:

y + 1 = 4(x + 2)

Which simplifies to:

y = 4x + 5

So the equation of the line that is parallel to y=−7+4x and passes through the point (-2,-1) is y = 4x + 5.

The graph of the proportional relationship represented by the equation y = 7.5x is The graph is a line that goes through points (0, 0) and (1, 7.5)

A linear function consists of functions where the variables has exponents of 1.

The graph of linear functions is a straight line graph and the relationship is expressed in the form.

y = mx + c

definition of variable to suit the problem

y = output variable

m = slope

x = input variable

c = y intercept

considering the given equation y = 7.5x.

c = 0

hence the graph passed through (0, 0)

substituting x = 1 gives y = 7.5 hence (1, 7.5) is another point

(a) 794g of the initial sample will be left in the sample after 25 years. (b) Time taken to decay to half of its original amount is 3.39 years.

Isotopes(200g) are atoms that have the same number of protons in their nucleus, but a different number of neutrons. This means that they have the same atomic number, but a different atomic mass. Because of this, isotopes have different physical and chemical properties. Isotopes can be stable, meaning that they do not undergo radioactive decay, or they can be unstable, meaning that they will undergo radioactive decay over time.

(a) Substituting 25 for t in the expression, we get:

[tex]A(25) = 200e^{0.0541 \times 25}[/tex]

         [tex]= 200e^{1.3525}[/tex]

Thus, after 25 years, there will be

[tex]200e^{1.3525} = 2003.97[/tex]

794 g of the initial sample left in the sample.

(b) We want to find t such that

[tex]A(t) = 200e^{0.0541}[/tex]                                          

       = 100.

Solving for t, we get:

[tex]= 200e^{0.0541} \times t=100[/tex]

Dividing both sides by 200 and applying the natural logarithm to both sides, we get:

0.0541 × t = ln(0.5)

Therefore,
