Answer:

x > 0

Step-by-step explanation:

To solve the inequality x/1 + 5 > 5, we first need to isolate the variable on one side of the inequality.

Subtracting 5 from both sides gives:

x/1 > 0

Multiplying both sides by 1 gives:

x > 0

Therefore, the solution to the inequality is x > 0.

The required probability of randomly selecting a white marble, replacing it, then randomly selecting another white marble is 4/25.

The probability of randomly selecting a white marble from the bag is 8/20, or 2/5, since there are 8 white marbles out of a total of 20 marbles (5 red, 8 white, and 7 green).

After replacing the first marble, there are still 8 white marbles and a total of 20 marbles in the bag. Therefore, the probability of randomly selecting another white marble is also 2/5.

To find the probability of both events happening (selecting a white marble, replacing it, and then selecting another white marble), we multiply the probabilities of the two events:

The probability of selecting a white marble and replacing it, then selecting another white marble = (2/5) x (2/5) = 4/25

Therefore, the probability of randomly selecting a white marble, replacing it, then randomly selecting another white marble is 4/25.

The correlation coefficient between the year and high temperature is approximately 0.9604,

To calculate the correlation coefficient between x (representing the year) and y (representing the high temperature), we can use the following steps:

1. Find the means of x, y, and their products.

   - Mean of x,  ¯  = (1+2+3+..+14)/14 = 7.5

   - Mean of y,  ¯    = (17.17+22.14+24.61+...+51.98)/14 ≈ 32.05

   - Mean of , ¯ = [(1* 17.17)+(2* 22.14)+...+(14* 51.98)]/14 ≈ 1312.925

2. Calculate the sample standard deviations of x and y.

  - Standard deviation of x, = √([∑(−¯)[tex]^2[/tex]]/(−1)) ≈ 4.3205

  - Standard deviation of y, = √([∑(−¯)^2]/(−1)) ≈ 10.8629

3. Calculate the covariance of x and y.

  - Covariance of x and y, cov(x,y) = [∑(−¯)(−¯)]/(−1) ≈ 51.7874

4. Calculate the correlation coefficient, r.

  - Correlation coefficient, r = cov(x,y) / ( ) ≈ 0.9604

Therefore,  indicating a strong positive linear relationship between x and y. The value of r being close to 1 suggests that as the year increases, so does the high temperature.

The amount of time it will take to completely fill the pool would be = 18 hours.

To determine the amount of time it will take to fill the pool, the volume of the pool is first calculated by dividing the figure to obtain two regular shapes of a trapezoidal prism and a square prism.

The volume of a trapezoidal prism = 1/2(a+b)×h×l

where;

a = 3m

b = 1m

h = 18-6 = 12m

l = 9m

Volume of the trapezoidal prism = 1/2(3+1)×12×9

= 4×12×9 = 432m³

Volume of square prism = length×width×height

where;

length = 6m

width = 9m

height = 1 m

Volume = 6×9×1 = 54m³

Therefore the volume of the pool = 432+54 = 486m³

If 4 hours = 2 m up from the deepest part

The volume filled for 4 hours = 1/2×2×12×9 = 108m³

If 4 hours = 108

[tex]tan\beta=\dfrac{8}{15}[/tex]

[tex]\csc\beta=\dfrac{17}{8}[/tex]

[tex]\cot\beta=\dfrac{15}{8}[/tex]

Step-by-step explanation:

The secant ratio is the reciprocal of the cosine ratio.

[tex]\sec \beta= \dfrac{1}{\cos \beta}[/tex]

Therefore, if sec β = 17/15 then:

[tex]\dfrac{1}{\cos \beta}=\dfrac{17}{15}[/tex]

[tex]\cos \beta=\dfrac{15}{17}[/tex]

The cosine of an angle is defined as the ratio of the length of the adjacent side to the length of the hypotenuse of a right triangle:

[tex]\cos\beta= \sf \dfrac{adjacent}{hypotenuse}[/tex]

Therefore, the length of the side adjacent angle θ is 15 and the length of the hypotenuse is 17.

[tex]\boxed{\begin{minipage}{9 cm}\underline{Pythagoras Theorem} \\\\$a^2+b^2=c^2$\\\\where:\\ \phantom{ww}$\bullet$ $a$ and $b$ are the legs of the right triangle. \\ \phantom{ww}$\bullet$ $c$ is the hypotenuse (longest side) of the right triangle.\\\end{minipage}}[/tex]

We can use Pythagoras Theorem to calculate the length of the side opposite angle β:

[tex]15^2+O^2=17^2[/tex]

[tex]O^2=17^2-15^2[/tex]

[tex]O=\sqrt{17^2-15^2}[/tex]

[tex]O=\sqrt{64}[/tex]

[tex]O=8[/tex]

Therefore, the length of the side opposite angle β is 8.

Now we have the lengths of the three sides of the right triangle, we can find the other trigonometric function of angle β.

[tex]\boxed{\begin{minipage}{8cm}\underline{Trigonometric functions}\\\\$\sf \sin\beta=\dfrac{O}{H}\quad\cos\beta=\dfrac{A}{H}\quad\tan\beta=\dfrac{O}{A}$\\\\\\$\sf\csc\beta=\dfrac{H}{O}\quad\sec\beta=\dfrac{H}{A}\quad\cot\beta=\dfrac{A}{O}$\\\\\\where:\\\phantom{ww}$\bullet$ $\beta$ is the angle.\\\phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle.\\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle.\\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse.\\\end{minipage}}[/tex]

Answer:

3.5 feet

Step-by-step explanation:

To determine whether you can jump a fence that is 7/6 of a yard tall, we need to convert the height to feet and compare it to your own jumping ability.

1 yard = 3 feet

So, 7/6 yards = (7/6) x 3 feet = 3.5 feet

Since a horse can jump a fence that is 4 feet tall and 4 feet is greater than 3.5 feet, it is likely that the horse can jump the fence while it may be more challenging for you to do so.

We can use the binomial probability formula to solve this problem.

P(X≥3) = 1 - P(X<3)

First, we need to find P(X<3), which means finding the probability of getting 0, 1, or 2 successes in 7 trials with a probability of success of 0.1.

P(X<3) = P(X=0) + P(X=1) + P(X=2)

P(X=k) = (n choose k) * p^k * (1-p)^(n-k)

P(X=0) = (7 choose 0) * 0.1^0 * 0.9^7 = 0.4783

P(X=1) = (7 choose 1) * 0.1^1 * 0.9^6 = 0.3830

P(X=2) = (7 choose 2) * 0.1^2 * 0.9^5 = 0.1144

P(X<3) = 0.4783 + 0.3830 + 0.1144 = 0.9757

P(X≥3) = 1 - P(X<3) = 1 - 0.9757 = 0.0243

There are 3125 different ways the nursing student can be assigned to different floors during a 5-day work week.

To determine the number of different ways a nursing student can be assigned to one of five different floors each day during a 5-day work week, we need to calculate the total number of possibilities.

Since the student can be assigned to any of the five floors each day, there are 5 options for each day. Since there are 5 days in a work week, we multiply the number of options for each day together:

Total number of possibilities = 5 options per day × 5 options per day × 5 options per day × 5 options per day × 5 options per day

Total number of possibilities = [tex]5^5[/tex] = 3125

Calculating this value, we find that there are 3125 different ways the nursing student can be assigned to different floors during a 5-day work week.

a. The concentration would be 0.5 mg/L at approximately t = 40 hours.

b. The table representing the concentration of the drug in the bloodstream, t hours after administration is shown below.

c. A reasonable domain for this function is t ≥ 0.

d. The patient should receive the next intravenous dose of the drug in order to maintain a concentration above 1 mg/L and below 8 mg/L at t = 1.25 hour.

e. The concentration of the oral drug and the concentration of the intravenous drug would keep increasing over the first 20 hours after it is administered.

In order to determine the time when the concentration would be 0.5 mg/L, we would substitute the value of the concentration and then solve the quadratic function for time (t);

c(t) = 20t/(t² + 4)

0.5 = 20t/(t² + 4)

0.5(t² + 4) = 20t

0.5t² + 2 = 20t

0.5t² + 2 - 20t = 0

t² + 4 - 40t = 0

t² - 40t + 4 = 0

Time, t = 38.8998 ≈ 40 hours.

Part b.

In this context, we would complete the table of values at various time (t) as follows;

t        0    2      4     6       8           10        12        14     16        18      20

Part c.

Since the concentration of the drug at time, t = 0 is equal to 0 mg/L and the concentration actually never becomes zero (0) for any value of time (t), we can reasonably infer and logically deduce that a reasonable domain for this quadratic function is t ≥ 0 or {0, ∞}.

Part d and e.

Furthermore, the intravenous drug must be administered to the patient between the time interval 1.25 ≤ t ≤ 20 in order to maintain a concentration above 1 mg/L and below 8 mg/L.

Let's calculate Donald Miller's earnings for the second week of November using the given information:
1. Determine the number of regular and overtime hours:
Donald worked 52 hours in total, with overtime paid for hours above 40. So he worked 40 regular hours and 12 overtime hours (52 - 40 = 12).
2. Calculate regular pay:
Donald earns $13 per hour for the regular hours. To find his regular pay, multiply the hourly rate by the number of regular hours worked: 40 hours * $13/hour = $520.
3. Calculate overtime pay:
The overtime rate is 1.5 times the hourly rate, so the overtime pay is $13 * 1.5 = $19.5 per hour. To find the total overtime pay, multiply the overtime rate by the number of overtime hours worked: 12 hours * $19.5/hour = $234.
4. Calculate the total pay for the second week of November:
Add the regular pay and overtime pay together: $520 (regular pay) + $234 (overtime pay) = $754.

We have,

A.

We know that for a geometric sequence, the ratio of consecutive terms is constant.

Let's call this ratio "r".

So, we have:

a2/a1 = r

a3/a2 = r

Substituting the given values, we get:

0.7/a1 = r

0.49/0.7 = r

Simplifying the second equation:

r = 0.7/0.49 = 1.4286...

Substituting this value in the first equation:

0.7/a1 = 1.4286...

Solving for a1:

a1 = 0.7/1.4286... = 0.49

Now we can use the formula for the sum of the first n terms of a geometric sequence:

Sn = a1(1 - r^n)/(1 - r)

Substituting the values we have found, and using n = 6, we get:

S6 = 0.49(1 - 1.4286^6)/(1 - 1.4286) ≈ 0.92

B.

We can rewrite the formula for the sum of the first n terms of a geometric sequence using rational exponents as:

Sn = a1(1 - r^n)/(1 - r^(1/n))

Substituting the values we have found, and using n = 6, we get:

S6 = 0.49(1 - 1.4286^6)/(1 - 1.4286^(1/6))^(6)

Simplifying the expression using a calculator, we get:

S6 ≈ 0.92
