Answer:
3p³ + 5p² - 8
Step-by-step explanation:
Given:
6p - 2
-6(-p-1) = 6p + 6
Subtract 6p + 6 from 3p³ + 5p² + 6p - 2 get your answer
= 3p³ + 5p² + 6p - 2 - (6p + 6)
= 3p³ + 5p² + 6p - 2 - 6p - 6
= 3p³ + 5p² - 8
3p³ + 5p² - 8 Should be added To -6(-p-1) to get 3p³+5p²+6p-2
Simon drove through some roadworks where the speed limit was 50 mph. Two cameras recorded the time taken to travel 1200 m through the roadworks as 56 seconds . Was Simon speeding through the roadworks ?
Answer:
[tex]Speed = 21.43m/s[/tex]
Step-by-step explanation:
Given
[tex]Distance = 1200m[/tex] -- of the roadworks
[tex]Time\ Recorded = 56s[/tex]
Required
Determine the speed
In this case:
[tex]Speed = \frac{Distance\ of\ Roadword}{Time\ Captured}[/tex]
[tex]Speed = \frac{1200m}{56s}[/tex]
[tex]Speed = 21.43m/s[/tex] --- approximated

63% of all people in the United States have at least some college education. If ten people were chosen at random, find the probability that exactly half have some college education.
Answer: 0.2417
Step-by-step explanation:
- 10! / (10-5)!5! x 0.53^5 x 0).47^5
To solve the problem we must know Binomial distribution.
The probability that exactly half have some college education is 17.3425%.
Given to us
The probability of a person having at least some college education = 63% = 0.63To solve the problem we will use the Binomial distribution, therefore,
The probability of a person having at least some college education, p = 63% = 0.63The probability of a person not having at least some college education, q = 37% = 0.37Number of people selected for college education (Sample Size) = 10Using the formula for Binomial Distribution,We want the probability that exactly half have some college education, therefore, x = 5
[tex]P(x) = ^nC_x\ p^x\ q^{(n-x)}[/tex]
Substitute the values we get,
[tex]P(5) = ^{10}C_5\ (0.63)^{5}\ (0.37)^{(10-5)}\\\\P(5) = ^{10}C_5\ (0.63)^{5}\ (0.37)^{5}\\\\P(5) = 0.173425 = 17.3425\%[/tex]
Hence, the probability that exactly half have some college education is 17.3425%.

Answer: x = 2
=============================================================
Explanation:
Refer to the diagram below.
I've added points D,E,F,G. This helps with labeling the segments and angles, and identifying the proper triangles (to see which are congruent pairs).
Triangle GEA is congruent to triangle GFA. We can prove this using the AAS congruence theorem. We have AG = AG as the pair of congruent sides, and the congruent pairs of angles are marked in the diagram (specifically the blue pairs of angles and the gray right angle markers)
Since triangle GEA is congruent to triangle GFA, this means the corresponding pieces segment GF and GE are the same length.
The diagram shows GF = 3x-4, so this means GE = 3x-4 as well.
----------------------
Through similar steps, we can show that triangle GEC is congruent to triangle GDC. We also use AAS here as well.
The congruent triangles lead to GD = GE. So GD = 3x-4. The diagram shows that GD = 6x-10
Since GD is equal to both 3x-4 and 6x-10, this must mean the two expressions are equal.
----------------------
Now let's solve for x
6x-10 = 3x-4
6x-3x = -4+10
3x = 6
x = 6/3
x = 2

dani rode her bike for 10 hours a day for 8 days . in this time she covered 576 miles. how many miles per day day did did dani average
Answer:
72 miles per day
Step-by-step explanation:
Step one data
we are told that Dani rode for 10 hours per day for 8 days
hence per day, the time taken is = 10 hours
Also,
Hence the average distance covered per day is
=total number of miles/total number of days
=576/8= 72 miles per day
Quadrilateral ABCD is transformed according to the rule (x,y)-> (X + 4, y + 6) to create A'B'C'D'.
A The lengths of ABCD are twice the corresponding side lengths of A'B'C'D'
B The angle measures of ABCD are equal to corresponding angle measures of A'B'C'D'
C The side lengths of A'B'C'D' are 4 units longer than ABCD
D The angle measures of A'B'C'D' are greater than the corresponding angle measures of ABCD
The value of x is ____ degrees, and the value of y is___degrees
Answer:
x = 112°, y = 68°
Step-by-step explanation:
68° and y are corresponding angles and are congruent, then
y = 68°
x and y are adjacent angles and are corresponding ( sum to 180° ), then
x + y = 180°
x + 68° = 180° ( subtract 68° from both sides )
x = 112°

The table shows a person saving money at a constant rate. How much is this person saving per week?
(Chart)
$------ 2-60. 4- 120. 6- 180. 8-240
(Answers)
A)$2.
B)$30.
C)$60.
D)$120
Answer:
We conclude that the person is saving $60 dollars per week.
Hence, option C is true.
Step-by-step explanation:
Given the table chart
Week Saving Money
2 60
4 120
6 180
8 240
We know to determine the slope to find the rate of change.
Taking the points (2, 60) and (4, 120)
Rate of change = Slope = [y₂ - y₁] / [x₂ - x₁]
= [120 - 60] / [4 - 2]
= 60 / 2
= $30 dollars per week
Now, taking the points (4, 120) and (6, 180)
Rate of change = Slope = [180 - 120] / [6 - 4]
= [60] / [2]
= $30 dollars per week
Now, taking the points (6, 180) and (8, 240)
Rate of change = Slope = [240 - 180] / [8 - 6]
= [60] / [2]
= $30 dollars per week
This concludes that the rate of change is contant i.e. $30 dollars per weekTherefore, we conclude that the person is saving $60 dollars per week.
Hence, option C is true.

Orchids are a family of thousands of types of flowers that all share the same shape. Many gardening clubs are devoted to collecting, studying, and growing orchids, because it is difficult to grow them outside of their natural habitats. Which are scientific questions that can be asked about a collection of different orchid types? Check all that apply. Which type needs the highest temperatures to grow in? Which type has the most beautiful colors? Do all of the types make food the same way? Do all of the types deserve the same amount of admiration? How can someone decide which type makes the best gift? How long does it take for a specific type to make its seeds?
Answer:
The correct options are;
1) Which type needs the highest temperature to grow
2) Do all of the types make food the same way
3) How long does it take for a specific type to make seeds
Step-by-step explanation:
The number of types of species in the orchid family = Several thousand
The tasks the gardening clubs are devoted to = Collecting, Studying, and growing of the orchids
The manner of the growth of the orchids = Difficulty observed in growing outside the orchid's natural habitat
Scientific questions are objective questions that are measurable, well defined about parameters that can be controlled which can be answered by means of an experiment and meant to provide a deeper understanding of the nature of the world around us
Therefore, the scientific questions that can be asked about a collection of different orchid types are;
1) Which type needs the highest temperature to grow
The above is a question that has a defined parameter (temperature) which is measurable and the answer can be provided by experimenting
2) Do all of the types make food the same way
An experiment with different orchid types will provide an answer to the above question
3) How long does it take for a specific type to make seeds
The length of time for it takes the seed to grow is measurable within an experiment.

{y=1/2x+4
{-1/2x+y=-5
Answer:
no solution
Step-by-step explanation:
Given the 2 equations
y = [tex]\frac{1}{2}[/tex] x + 4 → (1)
- [tex]\frac{1}{2}[/tex] x + y = - 5 → (2)
Substitute y = [tex]\frac{1}{2}[/tex] x + 4 into (2)
- [tex]\frac{1}{2}[/tex] x + [tex]\frac{1}{2}[/tex] x + 4 = - 5 , that is
4 = - 5 ← not possible
This indicates the system has no solution
