read the graph from left to right. As you move right from -4,-16, y increases as x increases. then once you hit zero there is no increase or decrease. Then from zero to 4 the y value is decreasing as x increases.

Answer:

x < -1

Step-by-step explanation:

Starting with the inequality:

18 < -3(4x-2)

First, distribute the -3:

18 < -12x+6

Next, isolate the variable term by subtracting 6 from both sides:

12 < -12x

Finally, divide both sides by -12, remembering to reverse the inequality since we are dividing by a negative number:

-1 > x

So the solution is x < -1.

The numerical value of x and the measure of segment BC are 1 and 5 respectively.

Given that; B is a point between A and C.

Since B is between A and C

AC = AB + BC

8 = 3x + 5x

Solve for x

8 = 8x

8x = 8

x = 8/8

x = 1

Next, determine the measure of BC,

BC = 5x

Plug in x = 1

BC = 5( 1 )

BC = 5

Therefore, x equal 1 and the measure of BC is 5.

2) We have negative numbers to help us understand the number system better. We need negative numbers in graphing.

The mean temperature in Cleveland, OH, was 64°F. The accumulated degree days for Cleveland on 6-7 September 2022 were 1. The rest of Ohio accumulated degree days during the same period.

Based on the given information, the maximum temperature in Cleveland was 70°F and the minimum temperature was 58°F. To find the mean temperature, we add the maximum and minimum temperatures and divide by 2: (70°F + 58°F) / 2 = 128°F / 2 = 64°F.

Degree days are a measure of heating or cooling requirements. In this case, since the mean temperature in Cleveland was lower than a certain base temperature, degree days were accumulated. The base temperature is typically set at 65°F for cooling and 55°F for heating. Since the mean temperature in Cleveland was below the base temperature, the accumulated degree days are heating degree days (HDD).

For the specific date of 6-7 September 2022, Cleveland accumulated 1 heating degree day (HDD). This means that the average temperature for that period was 1 degree below the base temperature of 55°F.

The remaining stations in Ohio also accumulated heating degree days (HDD) on 6-7 September 2022. This indicates that the temperatures across the rest of Ohio were below the base temperature during that period.

Answer:

10 km/h

Step-by-step explanation:

I'm not really sure about this but no ones answering your question and I wanna help.

So basically to calculate the average speed you need to divide the distance travelled by time taken

But you do not have the distance traveled. But it is mentioned that it takes u 30 minutes to walk from home to school when walking at 5 km/h so to find the distance all you have to do is... 30 x 5 = 150 km

Now that we have the time and distance all we have to do is find the average speed.

Average Speed = distance ÷ time

So 150 ÷ 15 = 10 km/h

The probability P(A and B)  that both events will occur is 8/13

From the question, we have the following parameters that can be used in our computation:

Event A = 6 and 6

Event B = 20 and 6

Event A and B = 6

Total = 6 + 6 + 20 + 6 - 6 + 20 = 52

Using the above as a guide, we have the following:

P(A) = 12/52

P(B) = 26/52

P(A and B) = 6/52

The probability that both events will occur is represented as

P(A and B) = P(A) + P(B) - P(A and B)

And this is calculated as

P(A and B) = P(A) + P(B) - P(A and B)

Substitute the known values in the above equation, so, we have the following representation

P(A and B) = 12/52 + 26/52 - 6/52

Evaluate

P(A and B) = 32/52

Simplify

P(A and B) = 8/13

Hence, the probability that both events will occur is 8/13

The work done to stretch the spring 9 m from equilibrium is 486 Joules. To find the work done to stretch the spring 9 m from equilibrium, we can use Hooke's Law.

States that the force required to stretch or compress a spring is directly proportional to the displacement from its equilibrium position. Given that a force of 36 N is required to keep the spring stretched 6 m from equilibrium, we can set up the proportion:

Force 1 / Displacement 1 = Force 2 / Displacement 2

36 N / 6 m = Force 2 / 9 m

Now, we can solve for Force 2:

Force 2 = (36 N / 6 m) * 9 m = 54 N

The force required to stretch the spring 9 m from equilibrium is 54 N.

To calculate the work done, we can use the formula:

Work = Force * Distance

Work = 54 N * 9 m = 486 J

The tires and the traction control system work in tandem to ensure maximum traction and stability, minimizing the risk of traction loss and improving overall vehicle control and safety.

The two most important parts of a vehicle in preventing traction loss are the tires and the traction control system.

Tires: Tires are the primary point of contact between the vehicle and the road surface. The quality and condition of the tires greatly influence traction. Tires with good tread depth and appropriate tread pattern are essential for maintaining grip on the road. Tread depth helps to channel water, snow, or debris away from the tire, preventing hydroplaning or loss of traction. Additionally, tire pressure should be properly maintained to ensure even contact with the road. Choosing tires suitable for the specific driving conditions, such as all-season, winter, or performance tires, is crucial for optimal traction and handling.

Traction Control System: The traction control system is a vehicle safety feature that helps prevent the wheels from slipping or spinning on low-traction surfaces. It uses various sensors to monitor the speed and rotation of the wheels. If the system detects a loss of traction, it will automatically reduce engine power and apply braking force to the wheels that are slipping. By modulating power delivery and braking, the traction control system helps maintain traction and prevent wheel spin, especially in challenging conditions like slippery roads or during quick acceleration.

The tires and the traction control system work in tandem to ensure maximum traction and stability, minimizing the risk of traction loss and improving overall vehicle control and safety.

The only way to really tell is to check it with the Pythagorean Theorem.

The Pythagorean Theorem describes every right triangle, and every triangle that fits the Pythagorean Theorem has a right angle in it.  Guaranteed.  This is incredibly handy.

If this IS a right triangle, then

(one leg squared) + (the other leg squared) = (the hypotenuse squared) .  

Let's check it out:

--  One leg squared = (11 cm)²  .  That's  121 cm² .

--  The other leg squared = (√99 cm)² .  That's  99 cm²  .

--  Their sum is  (121 + 99) cm² .  That's  220 cm² .

-- The hypotenuse squared is  (15 cm)² .  That's  225 cm² .

Is  220 cm² equal to  225 cm² ?

NO !  They are not equal.  They are different !

The sum of the squares of the legs is NOT equal to the square of the hippopotamus.

==>  This triangle does NOT fit the Pythagorean Theorem.

==>  It is NOT a right triangle.

(The angle in the bottom corner is slightly bigger than 90°.  But you can't tell by looking at it.  It's so close that you can only tell by checkoing the lengths againt the Pythagorean Theorem.)

When calculating a p-value, we always assume that the null hypothesis is true.TRUE/FALSE

The statement "When calculating a p-value, we always assume that the null hypothesis is true"

Answer: TRUE.

When calculating a p-value, we assume that the null hypothesis is true and use it as a basis for determining the probability of obtaining the observed sample results or more extreme results, assuming that the null hypothesis is true. If the resulting p-value is small (e.g., less than the chosen significance level), we reject the null hypothesis in favor of the alternative hypothesis. If the p-value is large, we fail to reject the null hypothesis. So, the null hypothesis serves as the reference point for calculating the p-value and making a decision about the hypotheses.

The amount of fencing needed to surround the perimeter of the picnic area of the park is 107 yards. Hence, the second option is the right choice.

In the question, we are informed that the triangle KLM, represents a section of a park set aside for picnic tables. We are also informed that the picnic area will take up approximately 400 square yards of the park.

We are asked for the amount of fencing needed to surround the perimeter of the picnic area of the park.

We know the area of a triangle can be found using the trigonometric area formula, Area = (1/2)ab sin C.

Using this in the given triangle KLM, we get:

Area = (1/2)(KL)(KM)(sin K),

or, 400 = (1/2)(KL)(45)(sin 25°),

or, KL = (400*2)/(45*sin 25°) = 800/(45*0.42262) = 800/19.017822 = 42.0658 ≈ 42 yd.

Thus, we get KL = 42 yards.

Now, the perimeter of the picnic area = the perimeter of the triangle KLM = KL + LM + MK = 42 + 20 + 45 yards = 107 yards.

Thus, the amount of fencing needed to surround the perimeter of the picnic area of the park is 107 yards. Hence, the second option is the right choice.
