Answer:

x ≥ 5, 8.25x + 10 = 175, and x = 20 hours.

Step-by-step explanation:

Let Lin works x hours per week.

Now given that Lin’s job pays $8.25 an hour plus $10 of transportation allowance each week.

And she has to work at least 5 hours a week to $175 per week.

So, the inequality that can be written from the above condition is x ≥ 5 .......(1)

And the equation that can be written that  

8.25x + 10 = 175 ....... (2)  

Now, fro equation (2) we can write x = 20 hours which satisfies equation (1).

The inequality of the situation is x ≥ 5, 8.25x + 10 = 175, and x = 20 hours.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

The number of integer solutions to the equation x + y + z = 20, where x, y, and z are all positive integers, is 18.

To find the number of integer solutions to the equation x + y + z = 20, where x, y, and z are positive integers, we can use a combinatorial approach known as "stars and bars."

Imagine representing the sum 20 as a row of 20 stars: ***************.

Now, we need to divide these stars into three groups (representing x, y, and z) using two bars (|). For example, ||****|*****| represents x = 2, y = 5, and z = 13.

To determine the number of integer solutions, we need to count the number of distinct arrangements of 20 stars and 2 bars. The stars can be placed in any of the 22 positions (20 + 2), and the bars can be placed in any of the 2 available positions. Thus, the number of arrangements is given by the binomial coefficient C(22, 2) = 231.

However, we need to exclude the cases where one or more variables (x, y, or z) equals zero. Since all variables must be positive, we need to subtract the number of solutions where one variable is zero. If we fix x = 0, we are left with the equation y + z = 20, which has C(21, 1) = 21 solutions. Similarly, fixing y = 0 or z = 0 yields 21 solutions each.

Therefore, the total number of integer solutions to the equation x + y + z = 20, with x, y, and z as positive integers, is 231 - 21 - 21 - 21 = 168 - 63 = 105.

Answer: QN = 12

Step-by-step explanation: This quadrilateral is a paralelogram because its 2 opposite sides (NP and MQ) are parallel and the other 2 (MN and PQ) are congruent.

In paralelogram, diagonals bisect each other, which means QR = RN.

If QR = RN:

QR = 6

Then,

QN = QR + RN

QN = 6 + 6

QN = 12

The diagonal QN of quadrilateral MNPQ is QN = 12.

The approximate side length of a square game board with an area of 160in² is equal to 12.6 inches.

As given in the question,

Area of the square game board is equal to 160in².

Let 'x' inches be the side length of the square game board.

Area of the square game board = (side length)²

There are several indices commonly used to measure effect sizes in independent samples t tests: Cohen's d, Hedges' g, and Glass's Δ.

These indices provide a standardized measure of the magnitude of the difference between the two groups.

Cohen's d is widely used and represents the difference between the means of two groups in terms of standard deviations. It is suitable for comparing means in studies with similar sample sizes.

Hedges' g is a modification of Cohen's d that corrects for potential bias when the sample sizes are unequal. It is recommended when the sample sizes of the two groups differ significantly.

Glass's Δ is another effect size measure that compares the means of two groups using the standard deviation of the control group as the reference. It is useful when the control group is considered the standard or reference group.

The choice of which effect size measure to use depends on the specific characteristics of the study, such as the equality of sample sizes and the role of the control group. Cohen's d is often used as a default choice, but Hedges' g and Glass's Δ are more appropriate when sample sizes differ or when a control group is present.

In a situation where a research report shows a large eta squared effect size (eta squared = .64) but a small and non-significant t value, it suggests that the effect size may be inflated due to other factors, such as a small sample size or high variability within groups. Eta squared is a measure of the proportion of variance accounted for by the independent variable, but it does not consider the precision of the estimate. The t value, on the other hand, takes into account both the effect size and the standard error of the estimate. Therefore, if the t value is small and not statistically significant, it suggests that the effect may not be reliable or robust.

Three factors that influence the size of the t value are the magnitude of the effect, the sample size, and the variability within groups. A larger effect size, larger sample size, and lower variability within groups all contribute to a larger t value. For example, if there is a large difference between the means of two groups, a larger sample size, and less variability within each group, it would result in a larger t value, indicating a more significant effect.

To identify the vertical asymptotes, we have to factor the denominator. For horizontal asymptotes, we compare the degrees of the numerator and denominator.

For rational functions, there are vertical and horizontal asymptotes. To identify the vertical asymptotes, we first have to factor the denominator. After that, we should look for values that make the denominator zero. These values can be found by setting the denominator equal to zero and solving for x. The resulting x values would be the vertical asymptotes of the function.

The horizontal asymptote is the line that the function approaches as x goes towards infinity or negative infinity. For rational functions, the horizontal asymptote is found by comparing the degrees of the numerator and the denominator.

If the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is y = 0. If the degree of the numerator is equal to the degree of the denominator, the horizontal asymptote is y = the ratio of the leading coefficients. If the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote.

Answer:

\(20\:\mathrm{miles}\)

Step-by-step explanation:

After travelling two hours, the two cruise ships form a triangle. One of the legs  of this triangle will be the distance Cruise A travelled, and another will be the distance Cruise B travelled. We can find the distance they travel using:

\(s=\frac{d}{t}, d=s\cdot t\)

Cruise A is travelling at 18 miles per hour for 2 hours. Therefore, Cruise A has travelled:

\(d=s\cdot t=18\cdot 2=36\:\mathrm{miles}\)

Cruise B is travelling at 15 miles per hour for 2 hours. Therefore, Cruise B has travelled:

\(d=s\cdot t=15\cdot 2=30\:\mathrm{miles}\)

Because we are given the angle between these legs, we can use the Law of Cosines to find the third leg. The Law of Cosines is given by:

\(c^2=a^2+b^2-2ab\cos C\), where \(a\), \(b\), and \(c\) are interchangeable. Let \(c\) represent the distance between the two cruises. We have:

\(c^2=36^2+30^2-2\cdot36\cdot30\cdot \cos 35^{\circ},\\c^2=426.63,\\c\approx \fbox{$20\:\mathrm{miles}$}\)(one significant figure).

9514 1404 393

Answer:

  20.7 miles

Step-by-step explanation:

The distance that A travels in the same direction as B is ...

  (18 mi/h)(2 h)cos(35°) = 29.489 mi

So, the difference in distances in that direction is ...

  (15 mi/h)(2 h) -29.489 mi = 0.511 mi

__

The distance A travels in the direction perpendicular to B is ...

  (18 mi/h)(2 h)sin(35°) = 20.649 mi

So, the straight-line distance between the ships is the hypotenuse of the right triangle with these distances as legs:

  AB = √(0.511² +20.649²) = √426.632 . . . miles

  AB = 20.655 miles ≈ 20.7 miles . . . separation after 2 hours

The probability of a radiation measurement of 599 or higher from a mountain known to have terrorists, assuming no nuclear danger, is about 0.0668.

We are given that the radiation levels observed by the satellite are normally distributed with a mean of 490 and a variance of 2916. We want to find the probability of a random radiation measurement being 599 or higher, assuming there is no nuclear danger.

First, we need to standardize the radiation level of 599 using the formula:

z = (x - mu) / sigma

where x is the radiation level, mu is the mean, and sigma is the standard deviation. Substituting the values we have:

z = (599 - 490) / √(2916) = 1.5

Now, we can use a standard normal distribution table or calculator to find the probability of a z-score of 1.5 or higher. The table or calculator will give us the area under the standard normal curve to the right of 1.5.

Using a calculator, we can find this probability as follows:

P(Z > 1.5) = 0.0668 (rounded to four decimal places)

Therefore, the probability of a random radiation measurement being 599 or higher is approximately 0.0668, assuming there is no nuclear danger.

Answer:

TOTAL TAX IS: $19.25

TOTAL PRICE IS: $294.25

MONEY LEFT IS: $135.75

Step-by-step explanation:

First, you do a proportion:

?/275 = 7/100

the ?/275 represents how much money in $275

the 7/100 represents 7% (7 hundredths)

then you cross multiply:

275 x 7 = 1925

then you divide:

1925 divided by 100 = 19.25

So $19.25 is the tax amount.

To get the total price, you add:

Tax ($19.25) + Cost($275) = $294.25

$294.25 is the total amount that Anna has to pay.

To get what Anna has left over, you subtract:

Has($430) - Spend($294.25) = $135.75

Anna has $135.75 left.

The approximate probability that Maurice will obtain a sample proportion less than 0.06 is 0.2119, rounded to three decimal places.

The population proportion is p = 0.08 since we are aware that the actual percentage of students who have not declared a major is 0.08. We are asked to estimate the likelihood that Maurice will acquire a sample fraction smaller than 0.06 from a simple random sampling of n = 250 students.

The sample proportion p' is a random variable with a mean equal to the population proportion p and standard deviation σ = √(p(1-p)/n). In this case, we have:

p = 0.08

n = 250

σ = √(0.08×(1-0.08)/250)

  = 0.025

To find the probability that p' < 0.06, we can standardize the variable using the standard normal distribution:

z = (p' - p) / σ

z = (0.06 - 0.08) / 0.025

 = -0.8

Using a standard normal distribution table or a calculator, we find that the probability of getting a z-score less than -0.8 is approximately 0.2119.

Therefore, the approximate probability that Maurice will obtain a sample proportion less than 0.06 is 0.2119, rounded to three decimal places.

The closest approximation of the volume of the cone that can be filled with flavored ice is approximately 5.379 cubic inches.

To find the volume of the cone that can be filled with flavored ice, we need to calculate the volume of the entire cone and subtract the volume of the bubble gum ball.

The volume of a cone can be calculated using the formula:

V_cone = (1/3) * π * r² * h

where r is the radius of the cone and h is the height of the cone.

Given:

Radius of the cone (r) = 1.75 inches

Height of the cone (h) = 3.5 inches

Diameter of the bubble gum ball = 0.5 inches

First, let's calculate the radius of the bubble gum ball using the diameter:

Radius of the bubble gum ball = Diameter / 2 = 0.5 / 2 = 0.25 inches

Now, we can calculate the volume of the cone:

V_cone = (1/3) * π * (1.75)² * 3.5

V_cone ≈ 5.444 cubic inches (rounded to three decimal places)

Next, let's calculate the volume of the bubble gum ball:

V_ball = (4/3) * π * (0.25)³

V_ball ≈ 0.065 cubic inches (rounded to three decimal places)

Finally, we subtract the volume of the bubble gum ball from the volume of the cone:

Volume of flavored ice = V_cone - V_ball

Volume of flavored ice ≈ 5.444 - 0.065 ≈ 5.379 cubic inches (rounded to three decimal places)

Therefore, the closest approximation of the volume of the cone that can be filled with flavored ice is approximately 5.379 cubic inches.

Answer:

x = 2

Step-by-step explanation:

Firstly, calculate the area of the rectangle with the formula:

Length x width = area

(x+6) * 3 = 3x + 18

The formula for the area of a triangle is:

\(\frac{1}{2} * b * h\)

We can plug the known variables into the equation and get:

\(\frac{1}{2} * 8 * (x+4)\)

4 * (x + 4)

4(x + 4)

4x + 16

As the two areas are the same:

4x + 16 = 3x + 18

Subtract 3x from both sides of the equation:

4x + 16 - 3x = 3x + 18 - 3x

x + 16 = 18

Subtract 16 from both sides of the equation:

x + 16 - 16 = 18 - 16

x = 2
