Answer:

1/3

Step-by-step explanation:

First, note that the spinner is divided into three, equal sections.

When need to find P(5 or odd) or, in other words, the probability of landing on either 5 or another odd number. The 3 numbers in the spinner are 4, 5, and 6. Only 5 is odd and the one we want.

Thus, the probability of landing on 5 or an odd number (in this case 5) is 1 out of 3, or 1/3 or around 33%.

The answer is 1/3

Complete question:

Hawkins Manufacturing Company produces connecting rods for 4- and 6-cylinder auto-mobile engines using the same production line. The cost required to set up the production line to produce the 4-cylinder connecting rods is $2,000, and the cost required to set up the production line for the 6-cylinder connecting rods is $3,500. Manufacturing costs are $15 for each 4-cylinder connecting rod and $18 for each 6-cylinder connecting rod. There is no production on weekends, so on Friday the line is diassembled and cleaned. On Monday, the line must be set up to run whichever product will be produced that week. Once the line has been set up, the weekly production capacities are 6000 6-cylinder connecting rods and 8000 4-cylinder connecting rods. Letx4 5 the number of 4-cylinder connecting rods produced next week x6 5 the number of 6-cylinder connecting rods produced next week s4 5 1 if the production line is set up to produce the 4-cylinder connecting rods; 0 if otherwise s6 5 1 if the production line is set up to produce the 6-cylinder connecting rods; 0 if otherwise

a) Using the decision variables x4 and s4, write a constraint that sets next week's maximum production of the 4-cylinder connecting rods to either 0 to 8000 units

b) Using the decision variables x6 and s6, write a constraint that sets next week's maximum production of the 4-cylinder connecting rods to either 0 to 6000 units

c) Write a constraint that requires that production be setup for exactly one of the two rods

d) Write the cost function to be minimized

Answer:

a) x₄ ≤ 8000s₄

b) x₆ ≤ 8000s₆

c) s₄ + s₆ = 1

d) MIN 15x₄ + 18x₆ + 2000s₄ + 3500s₆

Explanation:

a) The constraint that sets next week's maximum production of the 4-cylinder connecting rods to either 0 to 8000 units, is written as:

x₄ ≤ 8000s₄

b) The constraint that sets next week's maximum production of the 4-cylinder connecting rods to either 0 to 6000 units is written as:

x₆ ≤ 8000s₆

c) The constraint that requires that production be setup for exactly one of the two rods:

Since we have:

x₄ ≤ 8000s₄ ; x₆ ≤ 8000s₆

The constraint that requires that production be setup for exactly one of the two rods will be:

s₄ + s₆ = 1

d) Write the cost function to be minimized:

Since we are to find the cost function to be minimized, we take the function below:

MIN 15x₄ + 18x₆ + 2000s₄ + 3500s₆

a) If [tex]\mu_1[/tex] is the average learning rate of the 6th graders without background noise level and [tex]\mu_2[/tex] is the average learning rate of the 6th graders with background noise level

The Null Hypothesis is that the learning rate of the 6th graders is not affected by the background noise level.

Null hypothesis, [tex]H_0: \mu_1 = \mu_2[/tex]

b) The Alternative Hypothesis is that the learning rate of the 6th graders is affected by the background noise level.

Alternative hypothesis, [tex]H_a: \mu_1 \neq \mu_2[/tex]

c) Assumptions that must be met about the data before she can correctly use independent t-test

There must be random selection of the 6th graders

That the two groups are normally similar in their learning abilities

The division of students into the two groups should be at random

d) She has to  make these assumptions to prevent bias and inaccuracy of results. If these assumptions are not made, the outcome of the experiment may not reflect the true effect of background noise on the learning of the 6th graders.

She can still get accurate results if she include some bias in the selection to prove a particular result.

Answer:

All angles in any quadrilateral adds up to 360°

Step-by-step explanation:

We can prove this by using 180(n - 2)

n = 4 for a quadrilateral

180(4 - 2)

180(2)

360°

So, 360 - (125 + 67 + 80) = 88°

Answer:

See below

Step-by-step explanation:

The interior angles of a quadrilateral (having 4 sides) add up to 360 degrees.

=> So, to find x, we'll simply subtract the rest if the angles from 360

So,

=> x = 360-125-67-80

=> x = 88 degrees

Answer:

0

Step-by-step explanation:

The orders that the sides of the triangle ABC from longest to shortest length will be AB, BC, and AC.

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry. A right-angled triangle is a triangle having one of its angles with a measure of 90°. The slanted side of that triangle is called Hypotenuse and it is the longest side in that triangle.

If one of the angle is of 90°  then the triangle is right angled triangle.

We can see that the Hypotenuse is always the biggest side among all the sides.

Then the perpendicular side BC is the second biggest and then the base of the triangle.

Therefore, the order must be AB > BC > AC.

The orders that the sides of the triangle ABC from longest to shortest length will be AB, BC, and AC.

Answer:

triangle pythagora

Step-by-step explanation:

the pythagora is made by someone special names albert and you ahve to amke three sides a b and c

This is because we have two pairs of congruent sides (AB = CD and AC = CA) with a pair of congruent angles between them. Those angles are the alternate interior angles BAC and DCA

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

Similar to reason 2, but the converse means we go in reverse more or less. The original theorem states that if we have parallel lines, then the alternate interior angles are congruent. This time we know the alternate interior angles are congruent, so we conclude the lines are parallel.

Answer:

see below

Step-by-step explanation:

Reason 4 is SAS  AB = CD, BAC = DCA  and AC = CA so we have Two sides and the included angle

Reason 6 is if two lines are cut by a transversal and the alternate interior angles are congruent, then the lines are parallel.

Answer: x=48°

Step-by-step explanation:

The 3 angles of the triangle add up to 180°. We can set the angles to 180 and solve.

47+85+x=180               [combine like terms]

132+x=180                    [subtract both sides by 132]

x=48

Answer:

x=48

Step-by-step explanation:

Total sum of angles in a triangle =180

47+85+x=180

132+x=180

x=180-132

x=48

Answer:

B.90°counterclockwise

Answer: B

Step-by-step explanation:

A. If you rotate a figure in the first quadrant 180 degrees clockwise it will end up in the third quadrant so the answer can't be A.

B. If you rotate a figure in the first quadrant 90 degrees counterclockwise it will end up in the second quadrant because you will rotate it backwards and as you could see A prime is in the second quadrant.

C.If you rotate a figure in the first quadrant 180 counterclockwise it will end up in the third quadrant. SO the answer can't be it C.

D.If your rotate a figure in the first quadrant 270 counterclockwise it will end up in the fourth quadrant. So the answer can't be D.

C.  (x - 9)(x^2 + 9x + 81).

Step-by-step explanation:

The cube identities are

a^3 - b^3 = (a - b)(a^2 + ab + b^2)

a^3 + b^3 = (a + b)(a^2 - ab + b^2)

Checking against the list the one that fits is the difference formula:

x^2 - 9^2 = (x - 9)(x^2 + 9x + 81).

a=1, b = 9, ab = 1 *9 = 9.

Answer:

Step-by-step explanation:

There are 3 numbers that are either greater than 4 or less than 2. They are 1, 5, and 6. There is a 3/6 chance you roll one of them or 50% chance.

Hey there! :)

Answer:

P(greater than or less than 2) = 50%.

Step-by-step explanation:

Numbers greater than 4: 5, 6

Numbers less than 2: 1

Total of 3 numbers that fit the criteria. Therefore:

P(greater than 4 or less than 2) = # of numbers / total

P(greater than 4 or less than 2) = 3 / 6 = 1 / 2

Convert fraction to percent:

1/2 × 100 = 50%

Answer:

The car travels 83 1/3 meters in 3 seconds.

Step-by-step explanation:

Speed of car  = 100 KM/ hour

1 km= 1000m

1 hour = 3600 seconds

Lets find speed of car in Meters/second

speed of car in m/sec = 100*1000 m/3600 second

here we have taken 1000 for km and 3600 for hour

speed of car in m/sec = 100*1000 m/3600 second = 500/18 m/second

speed of car in m/sec = 250/9  m per sec

We know that

distance = speed*time

speed = 250/9  m per sec

time =3 second

distance = 250/9 * 3 meters = 250/3 meters = 83 1/3 meters.

Thus, car travels 83 1/3 meters in 3 seconds.

Answer: 6p^3+29p^2+22p-21

Answer:

Step-by-step explanation:

Since 15 liters of water flow through a water pipe and enter a tank within 4.5 minutes, the same amount of water would flow through a similar pipe at the same time. Therefore, if two similar water pipes are used, the volume of water that would flow into the tank in 4.5 minutes is 15 × 2 = 30 liters

Therefore, the time it will take to pump 727.5 liters of water into a water tank using 2 similar water pipes is

(727.5 × 4.5)/30 = 109.125 minutes
