Answer: option A is the correct answer.

Step-by-step explanation:

Looking at the table, the amount of medicine in her system is decreasing constantly with time. This constant amount by which this amount of medicine is decreasing is the decay constant.

Decay constant = 350/400 = 306.25/ 350 = 0.875

Let y represent the amount of medicine in her system after t hours.

Let a represent the initial amount of medicine in her system.

Let b represent the decay constant.

Let t represent the number of hours. Therefore, the function representing the exponential decay would be

y = 400b^t

When she wakes up at 7.00 am, the time from 5.00 pm would be 14 hours. Therefore

y = 400 × 0.875^14

Answer: there are 11 birds and 5 cats

Step-by-step explanation:

Let x represent the number of birds in the pet store.

Let y represent the number of cats in the pet store.

A bird has one head and a cat also has one head. The store manager says that there are 16 animal heads in the store. It means that

x + y = 16

A bird has 2 feet and a cat has 4 feet. The store manager says that there are 42 animal feet in the store. It means that

2x + 4y = 42 - - - - - - - - - - - - 1

Substituting x = 16 - y into equation 1, it becomes

2(16 - y) + 4y = 42

32 - 2y + 4y = 42

- 2y + 4y = 42 - 32

2y = 10

y = 10/2 = 5

x = 16 - y = 16 - 5

Answer:

There were 180 votes for blue.

Step-by-step explanation:

Given:

Riverside elementary school is holding a schoolwide election to choose a color. 5/8 of the votes were for blue. 5/9 of the remaining votes were for green and the remaining 48 votes were for red.

Now, to find the votes for blue.

Let the total votes be [tex]x.[/tex]

The votes for blue:

[tex]\frac{5}{8} \ of\ x[/tex]

[tex]=\frac{5}{8} \times x[/tex]

[tex]=\frac{5x}{8}[/tex]

Remaining votes are:

[tex]x-\frac{5x}{8} \\\\=\frac{8x-5x}{8} \\\\=\frac{3x}{8}[/tex]

The votes for green:

[tex]\frac{5}{9} \ of\ \frac{3x}{8} \\\\=\frac{5}{9} \times \frac{3x}{8} \\\\=\frac{15x}{72}[/tex]

The remaining votes for red = 48.

Now, the total votes are:

[tex]\frac{5x}{8} +\frac{15x}{72} +48=x\\\\\frac{45x+15x+3456}{72}=x\\\\\frac{60x+3456}{72}=x[/tex]

Multiplying both sides by 72 we get:

[tex]60x+3456=72x[/tex]

Subtracting both sides by 60[tex]x[/tex] we get:

[tex]3456=12x[/tex]

Dividing both sides by 12 we get:

[tex]288=x\\\\x=288.[/tex]

Thus, the total votes = 288.

Now, to get the votes for blue:

[tex]\frac{5}{8} \ of\ 288\\\\=\frac{5}{8}\times 288\\\\=0.625\times 288\\\\=180.[/tex]

Therefore, there were 180 votes for blue.

Option a)  Has an above average price-to-earning ratio                                            

Step-by-step explanation:

We are given the following in the question:

The price-to-earning ratio for firms in a given industry is distributed according to normal distribution.

For a particular firm the ratio x has a standard normal variable has a value,

z = 1

Formula:

[tex]z_{score} = \displaystyle\frac{x-\mu}{\sigma}[/tex]

[tex]1 = \dfrac{x - \mu}{\sigma}\\\\\sigma = x - \mu\\x = \mu + \sigma[/tex]

Thus, the firm has an above average price-to-earning ratio as the ratio is one standard deviation above the mean.

Option a)  Has an above average price-to-earning ratio

If a firm in a given industry has a standard normal variable value of Z=1, it signifies that the firm has an above average price-to-earning ratio.

A student has asked about the interpretation of a standard normal variable value, Z, in the context of a firm's price-to-earning (P/E) ratio in a given industry. If a firm has a Z-value of 1, it means that the firm's P/E ratio is one standard deviation above the mean for the industry. Since the standard normal distribution has a mean of 0 and a standard deviation of 1, a Z-value of 1 corresponds to performance that is better than average. Therefore, a correct interpretation of this scenario is a. Has an above average price-to-earning ratio.

The price-to-earning ratio for firms in a given industry is distributed according to a normal distribution. A firm with a standard normal variable value of Z=1 would have an above average price-to-earning ratio.

This is because the standard normal distribution has a mean of 0 and a standard deviation of 1. A Z-score of 1 corresponds to a value that is one standard deviation above the mean. Since the mean represents the average price-to-earning ratio in the industry, a firm with a Z-score of 1 would have a ratio that is above average.

x ≤ 10

1 ≤ x ≤ 10

The possible number of additional miles Chau can run ranges from 0 to 10 miles, which is expressed by the inequality t ≤ 10, where t represents the additional miles.

To find the possible number of additional miles Chau will run, we use the inequality that represents the situation:
Chau has run 18 miles and will run at most 28 miles in total. Thus, we have:

18 miles + t additional miles ≤ 28 miles

By isolating t, we subtract 18 from both sides of the inequality:

t ≤ 28 miles - 18 miles

t ≤ 10 miles

This inequality means that Chau can run at most 10 additional miles this week.

Therefore, the possible numbers of additional miles t that Chau can run range from 0 to 10 miles.

Domain 0<x<5

Step-by-step explanation:

Dimension of cardboard = 10 by 10

Let the length of box = 10-2x

Let the width of box = 10 - 2x

Let the height of box be =x

Volume = l×w×h

V = (10-2x)×(10-2x)×x

V= 100 - 40x +42 × x

V= 8x^3 -80x^2 +200x

The volume of the box as a function of x is 8x³ - 80x² + 200x

The formula to calculate volume will be:

= Length × Width × Height

The dimensions of the cardboard will be:

Length = 10 - 2x

Width = 10 - 2x

Height = x

Therefore, the volume will be:

= (10 - 2x) × (10 - 2x) × x

= 8x³ - 80x² + 200x

Therefore, the volume of the box as a function of x is 8x³ - 80x² + 200x.

Initial condition

[tex]f_0=0,f_1=1,f_2=1,f_3=2,f_4=3[/tex]

We have to show that Fibonacci numbers satisfies the recurrence relation.

The recurrence relation of Fibonacci numbers

[tex]f_n=f_{n-1}+f_{n-2}[/tex],[tex]f_0=0,f_1=1[/tex]

Apply this

[tex]f_n=(f_{n-2}+f_{n-3})+f_{n-2}=2f_{n-2}+f_{n-3}[/tex]

[tex]f_n=2(f_{n-3}+f_{n-4})+f_{n-3}=3f_{n-3}+2f_{n-4}[/tex]

[tex]f_n=3(f_{n-4}+f_{n-5})+2f_{n-4}=5f_{n-4}+3f_{n-5}[/tex]

Substitute n=2

[tex]f_2=f_1+f_0=1+0=1[/tex]

[tex]f_3=f_2+f_1=1+1=2[/tex]

[tex]f_4=f_3+f_2=2+1=3[/tex]

Hence, the Fibonacci numbers satisfied the given recurrence relation .

Now, we have to show that [tex]f_{5n}[/tex] is divisible by 5 for n=1,2,3,..

Now replace n by 5n

[tex]f_{5n}=5f_{5n-4}+3f_{5n-5}[/tex]

Apply induction

Substitute n=1

[tex]f_5=5f_1+3f_0=5+0=5[/tex]

It is true for n=1

Suppose it is true for n=k

[tex]f_{5k}=5f_{5k-4}+3f_{5k-5}[/tex] is divisible 5

Let [tex]f_{5k}=5q[/tex]

Now, we shall prove that for n=k+1 is true

[tex]f_{5k+5}=5f_{5k+5-4}+3f_{5k+5-5}=5f_{5k+1}+3f_{5k}=5f_{5k+1}+3(5q)[/tex]

[tex]f_{5k+5}=5(f_{5k+1}+3q)[/tex]

It is multiple of 5 .Therefore, it is divisible by 5.

It is true for n=k+1

Hence, the [tex]f_{5n}[/tex] is divisible by 5 for n=1,2,3,..

The Fibonacci sequence with its initial conditions does satisfy the given recurrence relation. With this, it can also be demonstrated that f5n is divisible by 5 for all positive integers n.

The problem involves a specific series in mathematics known as the Fibonacci series. We are given the Fibonacci numbers initial conditions: f0 = 0, f1 = 1, f2 = 1, f3 = 2, and f4 = 3. From these initial conditions, we can calculate the next values of the Fibonacci numbers.

Using the given Fibonacci numbers recurrence relation: fn = 5fn−4 + 3fn−5, we get:

So, fn = 5fn−4 + 3fn−5 is valid for n = 5, 6, 7, and presumably, for greater integers as well.

We then use this recurrence relation to show that f5n is divisible by 5, for n = 1, 2, 3, etc. This is immediately obvious for n = 1, because f5 = 5. But for n greater than 1, we can see that f5n = f(5*(n-1)+5) = 5f(5*(n-1)) + 3f(5*(n-1)-1), which will be divisible by 5 because 5 is a factor in the first term and the second term is also divisible by 5 according to our earlier results. This confirms that f5n is divisible by 5 for n = 1, 2, 3, and so on.

Final answer:

The least-squares regression line equation is ŷ = -1.72 + 2.18x. For x = 5, ŷ is approximately 9.88. For x = 9, ŷ is approximately 18.62.

Explanation:

To find the least-squares regression line, we need to use the formula ŷ = b0 + b1x, where b0 is the y-intercept and b1 is the slope. Using the coordinates of the given points, we can calculate the values of b0 and b1. Substituting these values into the formula, we get ŷ = -1.72 + 2.18x. For x = 5, we can plug this value into the equation: ŷ = -1.72 + 2.18(5) = 9.88. Similarly, for x = 9, we can substitute x into the equation: ŷ = -1.72 + 2.18(9) = 18.62.

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

For the given function:

[tex]a=2, b=-2\ and\ c=13[/tex]

Thus, we have:

[tex]x=\frac{-(-2)\pm\sqrt{(-2)^2-4(2)(13)}}{2(2)}[/tex]

[tex]x=\frac{2\pm\sqrt{4-104}}{4}[/tex]

[tex]x=\frac{2\pm\sqrt{-100}}{4}[/tex]

[tex]x=\frac{2\pm\sqrt{100}i}{4}[/tex]

[tex]x=\frac{2\pm10i}{4}[/tex]

[tex]x=\frac{2+10i}{4}[/tex]      and  [tex]x=\frac{2-10i}{4}[/tex]

[tex]x=\frac{2}{4}+\frac{10i}{4}[/tex]   and  [tex]x=\frac{2}{4}-\frac{10i}{4}[/tex]

[tex]x=\frac{1}{2}+\frac{5i}{2}[/tex]    and  [tex]x=\frac{1}{2}-\frac{5i}{2}[/tex]

Thus, the zeros of the given function are not real. The zeros of the function is at :

[tex]x=\frac{1}{2}+\frac{5i}{2}[/tex]    and  [tex]x=\frac{1}{2}-\frac{5i}{2}[/tex]

Answer:

The answer to your question is Area = 1024/243 or 4 52/243

Step-by-step explanation:

Data

length = 1 7/9

width = 3/4 of its length

Area = ?

Formula

Area of a rectangle = length x width

Process

1.- Convert the mixed fraction to improper fraction

      1 7/9 = (9 + 7) / 9 = 16/9

2.- Get the width

      16/9 / 3/4 = (16 x 4) / (9 x 3)

                       = 64 / 27

3.- Get the area

    Area = (16/9)(64/27)

             = 1024/243

             = 4 52/243

Answer:

2.37 square inches

Step-by-step explanation:

l = 16/9 = 1.78

b = 16/9 *3/4 = 1.33

Area = l * b

Area = 1.78 * 1.33

Area = 2.37 square inches

Answer:

The answer is C.

Step-by-step explanation:

810 (goal) - 510 (amount saved so far) = 300 (Balance left to achieve goal) divided by 5( months remaining to achieve goal) = $60 a month

The statement is Sheila needs to save $60 per month to achieve her goal, the option is C.

We are given that;

Monthly saving= $45

Bathroom remodel amount= $810

Now,

To find the answer, we need to calculate how much more Sheila needs to save and how many months she has left.

We can subtract the amount she has saved from the amount she needs to save:

810 - 510 = 300

So, Sheila needs to save $300 more. We can also subtract the number of months she has saved from the number of months in her plan:

18 - 13 = 5

So, Sheila has 5 months left. To find the monthly amount she needs to save, we can divide the remaining amount by the remaining months:

300 / 5 = 60

Therefore, by algebra the answer will be $60 per month.

The range of the body temperature is [tex]2\leq x\leq 35[/tex]

Explanation:

Let x denote the body temperature of the bees.

The maximum body temperature of the bee is 35° Celsius.

When they sleep, the body temperature can drop by up to 2° Celsius.

Thus, the minimum body temperature of the bee is 2° Celsius.

Thus, the range of the body temperature is from 35° Celsius to 2° Celsius.

The range of body temperature is given by:

[tex]2\leq x\leq 35[/tex]

Thus, the range in body temperature of the bees is [tex]2\leq x\leq 35[/tex]
