Jamal spends a total of $44 on lunch for his family, including tax and tip.

Algebraic expression can be defined as combination of variables and constants.

The total cost of the drinks is 4 x $1.75 = $7.

The total cost of the sandwiches is 4 x $7.50 = $30.

So, the subtotal before the tip is $7 + $30 = $37.

Since the prices include tax, we can directly add the tip to the subtotal to get the total amount Jamal spends:

Total cost = Subtotal + Tip = $37 + $7 = $44.

Therefore, Jamal spends a total of $44 on lunch for his family, including tax and tip.

Answer:

Therefore, the time for the return trip is:

≈ 5.306 seconds

Step-by-step explanation:

Let's start by finding the speed of the boat. We know that the boat travels 400m at a constant speed, so we can use the formula:

Speed = Distance / Time

Speed = 400m / Time (for one-way trip)

Let's assume that the time for the one-way trip is t. Then we can rewrite the speed formula as:

Speed = 400m / t

Now let's find the time for the return trip. We know that the boat travels the same route at the same speed for 2 minutes, which is equivalent to 120 seconds. This means that the distance traveled on the way back is:

Distance = Speed x Time

Distance = (400m / t) x 120 seconds

Distance = 48000m / t

We also know that when Pilar increases the boat's speed by 10 m/min, the return trip is 60 seconds faster. This means that the time for the return trip is:

t - 60 seconds

Using the same formula as before, the distance traveled on the return trip is:

Distance = (400m / (t + 1/2)) x (t - 60) seconds

Distance = (400m / (t + 1/2)) x (t - 60/60) minutes

Distance = 400m x (t - 60/60) / (t + 1/2) minutes

Now we know that the distance traveled on the way back is equal to the distance traveled on the way there:

48000m / t = 400m x (t - 60/60) / (t + 1/2)

Simplifying this equation, we get:

48 / t = 4 x (t - 1/3) / (t + 1/2)

Multiplying both sides by (t + 1/2), we get:

48(t + 1/2) / t = 4(t - 1/3)

Simplifying this equation, we get:

96 / t = 4t - 4/3

Multiplying both sides by t, we get:

96 = 4t^2 - 4/3t

Multiplying both sides by 3, we get:

288 = 12t^2 - 4t

Rearranging this equation, we get

12t^2 - 4t - 288 = 0

Dividing both sides by 4, we get:

3t^2 - t - 72 = 0

Using the quadratic formula, we can solve for t:

t = [1 ± sqrt(1 + 4(3)(72))] / 6

t = [1 ± sqrt(865)] / 6

Since t must be positive, we take the positive root:

t ≈ 6.366

Therefore, the time for the return trip is:

t - 60 seconds ≈ 6.366 - 60 seconds ≈ 5.306 seconds

Assuming the coordinates of point A are (3, 5): we would have the following results.

1. To reflect over the x-axis: the x-coordinate remains the same and the y-coordinate changes sign. So point B will have the same x-coordinate as point A (3), but the y-coordinate will be -5. Therefore, the coordinates of point B are (3, -5).

2. To reflect over the y-axis: the y-coordinate remains the same and the x-coordinate changes sign. So point C will have the same y-coordinate as point A (5), but the x-coordinate will be -3. Therefore, the coordinates of point C are (-3, 5).

3. To translate: add the given values to the x and y coordinates. So point D will have an x-coordinate of 3 + 3 = 6, and a y-coordinate of 5 + 4 = 9. Therefore, the coordinates of point D are (6, 9).

4. To rotate 180 degrees clockwise: flip the signs of both the x and y coordinates and then swap them. So point E will have an x-coordinate of -5 and a y-coordinate of -3. Therefore, the coordinates of point E are (-5, -3).

The distance a swimmer will travel if they swim from one corner to the opposite corner of an Olympic-size swimming pool is approximately 62.2 meters

The distance a swimmer will travel if they swim from one corner to the opposite corner of an Olympic-size swimming pool is approximately 62.2 meters. This can be calculated using the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. In this case, the length of the pool is one side of the right triangle, the width of the pool is the other side of the right triangle, and the distance the swimmer travels is the hypotenuse.

Using the Pythagorean theorem, we can calculate the distance the swimmer travels as follows:

a² + b² = c²

where a is the length of the pool (50 meters), b is the width of the pool (25 meters), and c is the distance the swimmer travels.

To solve for c, we can plug in the values for a and b and simplify as follows:

50² + 25² = c²

500 + 625 = c²

125 = c²√3

125 = c

Approximately 62.2 meters (rounded to one decimal place)

The base is the side opposite to the right angle and has a length of 14 units (given).

The side opposite to the angle of 17° is the "opposite" side.

a₁ = 2

a₂ = 2a₁ - 1 = 2(2) - 1 = 4 - 1 = 3

a₃ = 2a₂ - 1 = 2(3) - 1 = 6 - 1 = 5

a₄ = 2a₃ - 1 = 2(5) - 1 = 10 - 1 = 9

a₅ = 1a₄ - 1 = 2(9) - 1 = 18 - 1 = 17

the first 5 terms are 2 , 3 , 5 , 9 , 1 7

a. The necessary assumptions are the population variances are equal and combine the two sample variances into one.

b. The null and alternative hypotheses are defined.

c. The sample sizes are equal, and the sample standard deviations are approximately equal, we can safely assume equal variances and pool the sample variances.

d. The value of test statistic is 3.15 and p value is 0.05.

e. The mean diameter of bearings from machine 2 is greater than that of machine 1 at a 5% level of significance.

To begin the hypothesis test, the manager needs to state the null and alternative hypotheses. The null hypothesis (H0) is the statement of "no difference" between the mean diameters of bearings from the two machines. The alternative hypothesis (Ha) is the statement that the mean diameter of bearings from machine 2 is greater than that of machine 1.

In symbols,

H0: μ1 = μ2 (where μ1 is the mean diameter of machine 1 and μ2 is the mean diameter of machine 2) and

Ha: μ2 > μ1.

Before conducting the hypothesis test, we need to check some assumptions.

The next step is to calculate the test statistic and p-value. We use a t-test to compare the means of two independent samples. The test statistic is calculated as:

t = (x₁ - x₂) / [s_p x √(2/n)]

where x₁ and x₂ are the sample means, s_p is the pooled standard deviation, and n is the sample size.

Plugging in the numbers, we get:

t = (3.355 - 3.302) / [0.050 x √(2/50)] = 3.15

Using a t-distribution table with 98 degrees of freedom (n₁ + n₂-2), we find that the p-value associated with a t-value of 3.15 is less than 0.01.

Finally, we need to state our conclusion based on the p-value. Since the p-value is less than our significance level of 0.05, we reject the null hypothesis.

The sum of the arithmetic series of 28 + 28.4 ...+ 42 is 1260.

An arithmetic series is a sequence of numbers in which each term is obtained by adding a constant difference, called the common difference, to the preceding term.

To resolve this issue, we can utilise the following formula for the sum of an arithmetic series:

S = (n/2) * (a₁ + aₙ)

When n is the number of terms, a1 is the first term, and an is the nth term, S is the series total.

To find the number of terms, we need to figure out the pattern of the series. The common difference (d) is expressed as follows:

d = 28.4 - 28 = 0.4

To get from 28 to 42, we need to add (42 - 28)/0.4 = 35 terms.

So the number of terms is:

n = 35 + 1 = 36

The first term is a₁ = 28, and the last term is aₙ = 42.

Now we can plug these values into the formula:

S = (n/2) * (a₁ + aₙ)

= (36/2) * (28 + 42)

= 18 * 70

= 1260

The percentage of data between 13.8 and 30.2 in a normally distributed data set with a mean of 22 and a standard deviation of 4.1 is approximately 94.19%.

To solve this problem, we can first standardize the values of interest using the standard normal distribution formula, z = (x - μ) / σ, where x is the value of interest, μ is the mean, and σ is the standard deviation.

For the lower value of 13.8, we have z = (13.8 - 22) / 4.1 = -1.95. For the upper value of 30.2, we have z = (30.2 - 22) / 4.1 = 2.05.

Next, we can use a calculator to find the area between these two z-scores. Alternatively, we can use the complement rule to find the area to the left of -1.95 and the area to the right of 2.05, and subtract their sum from 1.

Using a calculator, we find that the area between -1.95 and 2.05 is approximately 0.9419 or 94.19%. Therefore, approximately 94.19% of the data falls between 13.8 and 30.2 in this normally distributed data set.
