Answer:
the answer is C, NOT B
Step-by-step explanation:
The system of inequalities will have more solutions than the system of equations , Option C is the corrrect answer.
What are Inequalities ?Inequality is the relation between two unequal numbers or algebraic expression.
The inequality symbols are less than , greater than , less than equal to, greater than equal to.
It is given in the question that
the system of equations y= -1/2x + 1 and y = x - 5.
the system of inequalities y > -1/2x + 1 and y < x - 5.
x-5 = -1/2 x +1
2x+x=6*2
3x = 12
x = 4
x-5 >-1/2 x +1
x>4
The system of inequalities generally have more solutions and in this case definitely have more solutions than the system of equations.

If the coefficient of determination is 0.394, what percentage of the data about the regression line is unexplained
Answer:
The percentage [regression line is unexplained] = 60.6%
Step-by-step explanation:
Given:
Coefficient of determination = 0.394
Find:
The percentage [regression line is unexplained]
Computation:
Coefficient of determination = 0.394
Coefficient of determination = 39.4%
The percentage [regression line is unexplained] = 100% - Coefficient of determination
The percentage [regression line is unexplained] = 100% - 39.4%
The percentage [regression line is unexplained] = 60.6%

Answer:
x=14
Step-by-step explanation:
If the square from GAI are 6 cm, then the other half of the triangle is also 6 inches long. Because it is not an even sided triangle, all the sides shouldnt be the same size. If you multiply 6 by 2 you get 12. 7 times 6 is 42. 42 divided by 3 is 14. The value of X should be 14.
Type ALL the steps of writing the equation of the line given the slope of the line is −4 and a point on the line is (−2,1).
Answer:
y = -4x - 7
Step-by-step explanation:
we use the slope intercept formula given by; y = mx + b
b = y intercept, which is when x = 0
m = slope
so they tell us the slope.. we just need to find b - the y intercept.
y = mx + b
plug in your coordinates (-2,1)
1 = -4(-2) + b
1 = 8 + b
1 - 8 = b
-7 = b
put it all together.
y = -4x - 7

Answer:
41º
Step-by-step explanation:
Because of parallel lines, (2x-5)º=180º-113º, so (2x-5)º=67º.
(2x-5)º=67º2x-5=67º2xº=72ºx=36ºThe angle that says (2x)º will be (2[36])º=72º.
So the other angle will be 180-67-72=41º as the sum of a triangle's interior angles is 180º.
Answer:
41°
Step-by-step explanation:
The angle below (2x-5) is also 113° (which i hope you know why)
Then to find (2x-5)° you would subtract 180 - 113 to get the angle because both those angles would add up to 180° because it is a straight angle which gives you 67°
Then you need to find x by solving the equation 2x - 5 = 67 which would give you x = 36, so you would multiply that by 2 for the angle on the side which would be 72°
Then bc the angles on the inside of the triangle all add up to 180° as well, you would add 72 + 67 = 139, then do 180 - 139 giving you d° as 41°

If a data set has mean of 150 and a standard deviation of 25, what is the z-score of an element with a value of 250?
Answer:
Z-score is 4
Step-by-step explanation:
N(150, 25^2)
Use z-score formula (can be found from internet with miu and sigma symbol)
[tex]z = \frac{250 - 150}{25} \\ z = \frac{100}{25} \\ z = 4[/tex]
Bill and Ted are each saving money for a trip to Europe. Bill started with $75 and saves an additional $15 per week. Ted began with $120 and saves an additional $10 per week. After how many weeks, x, will they have the same amount of money saved? Explain how you arrived at your answer.
Answer:
9 weeksStep-by-step explanation:
After x weeks Bill will save money:
75 + 15xAnd Ted will save:
120 + 10xSince they save same amount, we have equation:
75 + 15x = 120 + 10x15x - 10x = 120 - 755x = 45x = 45/5x = 9 weeksat one high school, the mean time for running the 100-yard dash is 15.2 seconds with a standard deviation of 0.9 seconds. the times are very closely approximated by a normal curve. find the percent of times that are at least 14.3 seconds
Answer:
The percent of times that are at least 14.3 seconds is approximately 16%.
Step-by-step explanation:
Let X denote the time for running the 100-yard dash.
It is provided that the times are very closely approximated by a normal curve.
So, the random variable X follows a normal distribution with a mean time of 15.2 seconds and with a standard deviation of 0.9 seconds.
Compute the probability of times that are at least 14.3 seconds as follows:
[tex]P(X\geq 14.3)=P(\frac{X-\mu}{\sigma}\geq \frac{14.3-15.2}{0.9})[/tex]
[tex]=P(Z\geq -1)\\\\=1-P(Z<-1)\\\\=P(Z<-1)\\\\=0.15866\\\\\approx 0.159[/tex]
*Use a z-table.
Thus, the percent of times that are at least 14.3 seconds is approximately 16%.
