Step-by-step explanation:

3x + 4x + x = 16

7x + x = 16

8x = 16

x = 16 : 8

x = 2

----------------------

3 × 2 + 4 × 2 + 2 = 16  (remember PEMDAS)

6 + 8 + 2 = 16

16 = 16

The number of miles that you ran on the treadmill on Monday will be 3 miles.

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

On Monday you run on the treadmill for thirty minutes at x mph and on Tuesday you walk a similar distance on the treadmill at 2 mph increasingly slow takes you three-fourths 60 minutes.

Then the distance is the same in both cases. Then we have

x × (1/2) = (x - 2) × (3/4)

Simplify the equation, then we have

x × (1/2) = (x - 2) × (3/4)

4x = 6(x - 2)

4x = 6x - 12

2x = 12

x = 6 miles per hour

The number of miles is given as,

D = 6 × 1/2

D = 3 miles

The number of miles that you ran on the treadmill on Monday will be 3 miles.

Answer:

He swam 1/2 mile more and biked 1  1/4 mile more in July

Step-by-step explanation:

June -- Bike    4 * ( 3  1/4)  = 13 miles

Step-by-step explanation:

a. Chad won the race as he reached the 120-yard mark in 24 seconds, while Patrick took 26.67 seconds.

b. It took Chad 20 seconds to catch up to Patrick.

c. Chad was 100 yards from the start of the race when he caught up to Patrick.

The area of classical mechanics known as kinematics examines object motion without taking into account the driving forces behind it.

Part a: To determine which boy won the race, we need to calculate the number of seconds it took each boy to reach the 120-yard mark.

We can do this by setting their respective equations equal to 120 and solving for s.

For Chad:

y = 5s

120 = 5s

s = 24

For Patrick:

y = 3s + 40

120 = 3s + 40

3s = 80

s = 26.67

Therefore, Chad won the race as he reached the 120-yard mark in 24 seconds, while Patrick took 26.67 seconds.

Part b. We can determine how many seconds it took for Chad to catch up to Patrick by setting their equations equal to each other and solving for s.

y = 5s

y = 3s + 40

5s = 3s + 40

2s = 40

s = 20

Therefore, it took Chad 20 seconds to catch up to Patrick.

Part c. To determine how many yards from the start of the race Chad was when he caught up to Patrick, we can substitute s = 20 into Chad's equation and solve for y.

y = 5s

y = 5(20)

y = 100

Therefore, Chad was 100 yards from the start of the race when he caught up to Patrick.

The "hypothesis of no change," "status quo," and "conventional wisdom" are all alternative names for the null hypothesis. Unless there is overwhelming evidence to the contrary, the null hypothesis is assumed to be correct.

H0: u = 1: u ≠ 1,400

When testing hypotheses with the P value, the null hypothesis is rejected if?

The evidence against the null hypothesis is stronger when the p-value is smaller (closer to 0).If the p-esteem is not exactly or equivalent to the predetermined importance level α, the invalid speculation is dismissed;The null hypothesis is not rejected otherwise.

A statement of expectation or prediction that will be tested by research is called a research hypothesis. Read up on the subject that interests you before coming up with your research hypothesis.

Answer:

0.75x=(total cost)

Step-by-step explanation:

Answer:

The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.

A function relating these variables is A(x) =0.75x .

So A(12) = 9, meaning 12 bagels will cost 9 dollars.

The probability is 0.296 Therefore, the probability that a soccer player who tests positive takes steroids is about 0.296 or 29.6%

To find the probability that a soccer player who tests positive takes steroids, we can use Bayes' theorem.
1. Define the events:
A: A player takes steroids.
B: A player tests positive for steroids.

2. We are given the following probabilities:
P(B|A) = 0.96 (probability of testing positive given that a player takes steroids)
P(B|A') = 0.12 (probability of testing positive given that a player doesn't take steroids)
P(A) = 0.05 (probability that a player takes steroids)

3. We need to find P(A|B), the probability that a player takes steroids given that they tested positive.
The probability that a soccer player who tests positive takes steroids can be calculated using Bayes' theorem:
P(Steroids | Positive) = P(Positive | Steroids) * P(Steroids) / P(Positive)
where P(Positive | Steroids) = 0.96 (96% of players taking steroids test positive), P(Positive | No Steroids) = 0.12 (12% of players not taking steroids test positive), and P(Steroids) = 0.05 (5% of soccer players take steroids).

4. Bayes' theorem states:
P(A|B) = (P(B|A) * P(A)) / P(B)

5. We first need to find P(B). We can do this using the law of total probability:
P(B) = P(B|A) * P(A) + P(B|A') * P(A')

6. We know P(A) and can calculate P(A') as the complement:
P(A') = 1 - P(A) = 1 - 0.05 = 0.95

7. Now, we can calculate P(B):
P(B) = 0.96 * 0.05 + 0.12 * 0.95 = 0.048 + 0.114 = 0.162

8. Finally, we can calculate P(A|B) using Bayes' theorem:
P(A|B) = (0.96 * 0.05) / 0.162 ≈ 0.2963

The probability that a soccer player who tests positive takes steroids is approximately 0.296, or 29.6%.

The perimeter of △XYZ is 54 cm.

To find the perimeter of △XYZ given that △ABC∼△XYZ with side lengths AB=18 cm, BC=30 cm, and CA=42 cm, and the longest side of △XYZ is 25.2 cm, follow these steps:

1. Identify the longest side of △ABC. In this case, it is CA with a length of 42 cm.
2. Calculate the scale factor by dividing the longest side of △XYZ (25.2 cm) by the longest side of △ABC (42 cm): 25.2 / 42 = 0.6.
3. Find the corresponding side lengths of △XYZ by multiplying the side lengths of △ABC by the scale factor (0.6):
  - XY (corresponding to AB): 18 * 0.6 = 10.8 cm
  - YZ (corresponding to BC): 30 * 0.6 = 18 cm
  - XZ (corresponding to CA): 42 * 0.6 = 25.2 cm (already given)
Calculate the perimeter of △XYZ by adding the side lengths: 10.8 + 18 + 25.2 = 54 cm.

The perimeter of △XYZ is 54 cm.

Answer:

280%

Step-by-step explanation:

67,500 divided by 2,025 is 280.25

Assuming the amount of ingredients given are enough to make one batch, and the chef had enough celery and garlic.

We can see : For one batch to be made, 2 cups of onions and 3 cups of carrots are used.

-> 5 cups combined.

Since a total of 20 cups of the same ingredients were used, we can deduce the number of batches the chef made by dividing it by 5.

-> 20 : 5 = 4 (batches)

The given problem involves integrating a complex function counterclockwise along a specific curve in the complex plane. The curve is defined by the equation |z-1| = 6.

To solve the problem, we need to integrate the function 2+6dz counterclockwise along the curve C defined by |z-1| = 6. Let's break down the solution into two parts: first, we determine the parametric representation of the curve C, and then we perform the integration.

The equation |z-1| = 6 represents a circle centered at z = 1 with a radius of 6. By applying the parametrization z = 1 + 6\(e^{(it)}\), where t is the parameter ranging from 0 to 2π, we can represent the curve C in a parametric form.

Next, we substitute this parametric form into the integral and rewrite the differential dz using the chain rule. The given integral becomes ∫(2+6(1 + 6\(e^{(it)}\)))i(6\(e^{(it)}\))dt.

Expanding and simplifying, we have ∫(2 + 6i + 36i\(e^{(it)}\) - 36\(e^{(it)}\))dt.

Integrating term by term, we get the result as 2t + 6it - 36\(e^{(it)}\). Evaluating the integral from 0 to 2π, we substitute these values into the result expression.

Finally, simplifying the expression, the integrated value for the given problem is 4π - 12i.

In conclusion, integrating counterclockwise 2+6dz = Joz-2 2+6 Joz-2 dz along the curve C, where |z-1| = 6, results in a value of 4π - 12i.
