Tyler gather data and notices that the number of crimes in Glendale and the number of students enrolled in schools have a strong positive correlation tell a proposes closing down schools as a solution to reduce or illuminate crime in Glendale what do you recommend to the Glendale city Council
Answer:
The fact that the number of crimes and the population of students is positively correlated, means that as the total number of students increases, so does the total number of crimes.
The conclusion that closing schools will decrease crime is absurd. First of all, the variables might be totally unrelated, e.g. places with large number of students are places that have high populations. Higher crime rate are generally linked to neighborhoods or cities with high populations.
The idea of closing schools to fight crime is foolish because it will result in the opposite. Generally, students who go to school tend to be less engaged in criminal activities. The real problem here is that you should try to increase the number of students that attend schools in Glendale, not vice versa.
What's the answer to this problem 2x + 1=11
Answer:
5
Step-by-step explanation:
first u subtract the 1 from both sides and leaves u with 2x=10 then divide on both sides and you get 5
Step-by-step explanation:
2x+2=11
2x=11-2
2x=9
divide both sides by 2
therefore the answer is 4.5
The online price for a box of hair clips is $2.60. For any number of boxes purchased, the cost of shipping is $12. The equation c=2.60b + 12 represents the total cost, c, of ordering b boxes of hair clips. If Mrs. Hilton orders 32 boxes of hair clips, what is the total cost? (6.EE.C.9)
Answer:
$43.2Step-by-step explanation:
Step one:
given data
the total cost function is
c=2.60b + 12
Step two:
Required is c, when b= 12
substitute b=12 we have
c=2.60(12) + 12
c=31.2+ 12
c=43.2
the total cost = $43.2
Solve, then enter one of the vales of your solutions below. x^2 + 25 =169
Answer:
12
Step-by-step explanation:
-25 from both side
x^2= 144
then you square root it
x= 12
[tex]\huge\text{Hey there!}[/tex]
[tex]\mathsf{x^2 + 25 = 169}[/tex]
[tex]\text{Subtract 25 to both sides}\downarrow[/tex]
[tex]\mathsf{x^2 + 25 - 25 = 169 - 25}[/tex]
[tex]\text{Simplify it}\downarrow[/tex]
[tex]\mathsf{x^2 = 169 - 25}[/tex]
[tex]\mathsf{x^2 = 144}[/tex]
[tex]\text{Take the square root of the numbers (including the mystery number (x))}\downarrow[/tex]
[tex]\mathsf{x = \pm \sqrt{144}}[/tex]
[tex]\text{So, that means that}\downarrow[/tex]
[tex]\mathsf{x = 12}[/tex]
[tex]\text{Or even:}[/tex] [tex]\mathsf{x = -12}[/tex]
[tex]\huge\text{Therefore, your answer should be:}[/tex]

Use the graph to identify the slope and y-intercept. Can you help me identify them?.
Answer:
y intercept is (0,4) and slope is -2
Step-by-step explanation:
y intercept is (0,4) you can see where it intercepts.
The slope is rise/run so 4/-2 so -2

whats the equation for a line thats perpendicular to 6x-2y=8 when it passes through (6,-5)
( i hope i wrote that right sorry)
Answer:
Equation of required line is: [tex]\mathbf{x+3y=-9 }[/tex]
Step-by-step explanation:
We need to find equation for a line that's perpendicular to [tex]6x-2y=8[/tex] when it passes through (6,-5)
We will use the slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
Finding Slope m:
When two lines are perpendicular there slopes are [tex]m=-\frac{1}{m}[/tex]
Finding slope of given equation first: [tex]6x-2y=8[/tex]
Writing in slope-intercept form:
[tex]6x-2y=8\\-2y=-6x+8\\y=\frac{-6x}{-2}+\frac{8}{-2}\\y=3x-4[/tex]
Comparing it with slope intercept form: [tex]y=mx+b[/tex] , m= 3
So, slope of given equation is 3
Now, the slope of required equation will be [tex]m=-\frac{1}{m}[/tex]
So, Slope m=-1/3
Finding y-intercept
Using slope m=-1/3 and point (6,-5) we can find y-intercept
[tex]y=mx+b\\-5=\frac{-1}{3}(6)+b\\-5=-2+b\\b=-5+2\\b=-3[/tex]
So, y-intercept is b=-3
Now, finding the equation of required line having Slope m=-1/3 and y-intercept b= -3
[tex]y=mx+b\\y=-\frac{1}{3}x-3[/tex]
Writing in standard form:
[tex]y=-\frac{1}{3}x-3\\y=\frac{-x-9}{3}\\3y=-x-9\\x+3y=-9[/tex]
So, equation of required line is: [tex]\mathbf{x+3y=-9 }[/tex]

Solve z = -10x, for x.
Answer:
B
Step-by-step explanation:
z = -10x
z + 10 = -10x + 10 = x
Answer: D
If z = -10x, we can divide both sides of the equation by -10 to get z/(-10) = x. This is the same as [tex]x=-\frac{z}{10}[/tex].

Explain why the sum of the angle measures in any triangle is 180
Answer:
Step-by-step explanation:
Because every triangle that can ever be made has three sides, you can open up the triangle so that it becomes a straight horizontal line. A horizontal line is also 180 degrees which is why this idea works with triangles.
The reason for the sum of the angles in any triangle is 180 is that when we open up the sides of a triangle we get a straight line where the angle of a straight line is 180 degrees.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles has are equal to 180 degrees.
We have,
The sum of the angle measures in any triangle is 180.
We see that,
In a triangle, there are three sides and three angles.
If we open up the triangle, we see that the three sides of the triangle form a straight line.
The angle of a straight line is 180 degrees.
Thus,
The reason for the sum of the angles in any triangle is 180 is that when we open up the sides of a triangle we get a straight line where the angle of a straight line is 180 degrees.
