Answers
This is because 15% of 4000 is 600.
You get this by doing 0.15 * x = 600 and solving for x

16x^(5)+24x^(2)=4x^(2)(4x^(3)+6)
Answers
Answer:
Option d
Step-by-step explanation:
Given options are ,
12x² + 8x = 4x( 3x + 2)Firstly find the GCF of 12x² and 8x .
The GCF of 12 and 8 is 4 , whereas the GCF of x² and x is x , So
→ GCF(12x² , 8x) = 4*x = 4x
Therefore the GCF is correctly factored out from the polynomial .
______________________________________
15x² + 12x + 9 = 3(5x² + 4x +3)Here GCF of 15x² , 12x and 9 , will be ;
GCF of 15,12 and 9 is 3 whereas of x² , x and 1 is 1
→ GCF = 3*1 = 3
Therefore the GCF is correctly factored out from the polynomial .
______________________________________
4x⁴+ 12x³ +18x² = 2x²(2x² + 6x + 9 )Here GCF of 4 , 12 and 18 is 2 and that of x⁴ , x³ and x² is x² . So ,
→ GCF = 2*x² = 2x²
Therefore the GCF is correctly factored out from the polynomial .
______________________________________
16x^5 + 24x² = 4x²( 4x³ + 6 )Here GCF of 16 and 24 is 8 and that of x^5 and x² is x² . So ,
→ GCF = 8*x² = 8x²
But they have factored out 4x² .
Therefore the GCF is " not " correctly factored out from the polynomial .
Option d is correct .

Find two values for x that make the inequality true.
-5x<2
giving brainliest answer quick
Answers
Answer: See below
Step-by-step explanation:
-5x<2 means -5x is less than 2, so a decimal under 0.4 (but not equal to) such as 0.3, 0.2, and 0.1 would all make the inequality true
Ex. Let x = 0.2
-5(0.2) < 2
1 < 2
1 is less than 2, so the inequality is true

Answers
Step-by-step explanation:
2^x < 2x³ + 1 ?
that would mean
x < log2(2x³ + 1)
x < log2(2×(x³ + 1/2))
x < log2(2) + log2(x³ + 1/2)
x < 1 + log2(x³ + 1/2)
x - 1 < log2(x³ + 1/2)
for large x the "-1" and the "+ 1/2" are becoming relatively irrelevant for the inequality.
and the limes of this goes to
x < log2(x³)
which is not true for large x, as the logarithm turns into a very flat curve, while "x" just keeps growing with slope 1 and therefore outpaces the logarithm.
for x = 20 for example, 2^x is already way larger than 2x³.
the "cross-over" point is between x=11 and x=12.
from there on 2^x will quickly become much larger than 2x³ + 1.

Answers
Answer:
a) No because the gallons and quarts of oil you and your friend bought is proportional.
b) Yes because the gallons and quarts of oil are no longer proportional.
c) 1 gallon of gasoline = $3.55
1 quart of oil = $5.00
Step-by-step explanation:
Let g = cost per gallon of gasoline
Let q = cost per quart of oil
a) Creating expressions from the given information:
10g + 2q = 45.50
5g + q = 22.75
From inspection, we can see that if we multiply the second equation by 2, it will give us the first equation. Therefore, they are proportional and we cannot determine the variables.
b) Creating expressions from the given information:
10g + 2q = 45.50
5g + q = 22.75
8g + 2q = 38.40
From inspection, we can see that the third equation is not proportional to equations 1 and 2. Therefore, we can use this equation with either of the other equations to determine the variables.
c)
Using equations 2 and 3 from the previous part (b):
5g + q = 22.75
8g + 2q = 38.40
Rewrite 5g + q = 22.75 to make q the subject:
⇒ q = 22.75 - 5g
Substitute into 8g + 2q = 38.40 and solve for g:
⇒ 8g + 2(22.75 - 5g) = 38.40
⇒ 8g + 45.5 - 10g = 38.40
⇒ 2g = 7.1
⇒ g = 3.55
Substitute found value for g into q = 22.75 - 5g and solve for q:
⇒ q = 22.75 - (5 x 3.55)
⇒ q = 5

Offering career academies in high schools has become more popular during the past 30 years because they help students prepare for work and postsecondary education. A principal at a large high school with a Science, Technology, Engineering, and Mathematics (STEM) Academy is interested in determining whether the status of a student is associated with level of participation in advanced placement (AP) courses. Student status is categorized as (1) STEM for students in the STEM program or (2) regular. A simple random sample of 200 students in the high school was taken and each student was asked two questions:
Are you in the STEM Academy?
In how many AP courses are you currently enrolled?
The responses of the 200 students are summarized in the table.
Level of Participation in Advanced Placement (AP) Courses Student Status
STEM Regular Total
No AP courses 17 31 48
One AP course 38 70 108
Two or more AP courses 20 24 44
Total 75 125 200
Part A: Calculate the proportion of STEM students who participate in at least one AP course and the proportion of regular students in the sample who participate in at least one AP course.
Part B: Is participating in two or more AP courses independent of student status?
Part C: Describe a method that could have been used to select a simple random sample of 200 students from the high school.
Part D: Is there any reason to believe there is bias in the method that you selected? Why or why not?
Part E: The responses of the 200 students are summarized in the segment bar graph shown.
Compare the distributions and what the graphs reveal about the association between level of participation in AP courses and student status among the 200 students in the sample. (5 points)
Part F: Do these data support the conjecture that student status is related to level of participation in AP courses? Give appropriate statistical evidence to support your conclusion. (10 points)
Answers
The proportion of STEM students who participate in at least one AP course is 0.19.
How to calculate proportionIt can be deduced that the proportion of STEM students who participate in at least one AP course will be:
= 38/200
= 0.19
The proportion of regular students in the sample who participate in at least one AP course will be:
= 70/200
= 0.35
Also, participating in two or more AP courses is independent of student status. This is because the p value is more than the 0.05.
A method that could have been used to select a simple random sample of 200 students from the high school is by writing all the registration numbers of the students in a container an randomly picking.
There is bias in the sampling because the convenience sampling is used. This doesn't give everyone an equal chance.
In conclusion, status is not related to level of participation in AP courses.

Answers
The x- and y- coordinates of point P on the directed line segment from K to J such that P is Three-fifths the length of the line segment from K to J is (85, 105).
Given
On a coordinate plane, a line is drawn from point K to point J. Point K is at (160, 120) and point J is at (negative 40, 80).
CoordinatesThe coordinates point any point can be found by using the following formula.
[tex]\rm X=\dfrac{m}{m+n}(x_2-x_1)+x_1\\\\ Y=\dfrac{m}{m+n}(y_2-y_1)+y_1[/tex]
The x- and y- coordinates of point P on the directed line segment from K to J such that P is Three-fifths the length of the line segment from K to J is;
[tex]\rm X=\dfrac{m}{m+n}(x_2-x_1)+x_1\\\\ X = \dfrac{3}{3+5}(-40-160)+160\\\\ X = 3 \times (-25)+160\\\\\X = -75+160\\\\ X = 85\\\\\ Y=\dfrac{m}{m+n}(y_2-y_1)+y_1\\\\ Y=\dfrac{3}{3+5}(80-120)+120\\\\Y =- 3\times 5 +`120\\\\Y=-15+120\\\\Y=105[/tex]
