Answer:
NOREAL SOLUTION
Step-by-step explanation:
6x2+125=x2
Step 1: Subtract x^2 from both sides.
6x2+125−x2=x2−x2
5x2+125=0
Step 2: Subtract 125 from both sides.
5x2+125−125=0−125
5x2=−125
Step 3: Divide both sides by 5.
Step 4: Take square root.

find the perimeter of a rectangle if one of its sides is 14 and the area is 98
Answer:
42
Step-by-step explanation:
Area of a rectange = bh so 98=14x
98 divided by 14 = 7
Perimeter= 2x+2y
so 2x+2y -> 28+14=42

Madison Plans to walk and run a total of 1 4/5 mi on a treadmill. She has already walked 2/5 mi and plans to run the rest of the distance. Madison wants to know the distance she needs to run. Let r be the distance in miles that Madison needs to run. Describe this situation in an equation. Pls I need help on this. This is Iready.
Answer:
its 1 4/5 = 2/5 + r
Step-by-step explanation:
The distance in miles that Madison needs to run is [tex]1 \frac{2}{5}[/tex] miles.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Madison Plans to walk and run a total of [tex]1\frac{4}{5}[/tex] =9/5 miles on a treadmill.
Let r be the distance in miles that Madison needs to run.
Now, the equation is
2/5 +r =9/5
r= 9/5 - 2/5
r =7/5
r = [tex]1 \frac{2}{5}[/tex] miles
Therefore, the distance in miles that Madison needs to run is [tex]1 \frac{2}{5}[/tex] miles.

(b) Claude
goes to school by bus.
The probability that the bus is late is 0.1. If the bus is late, the
probability that Claude is late to school is 0.8.
If the bus is not late, the probability that Claude is late to school is 0.05.
i) Calculate the probability that the bus is late and Claude is late to school.
ii) Calculate the probability that Claude is late to school.
iii) The school term lasts 56 days.
How many days would Claude expect to be late?
Answer:
i) 0.08 = 8% probability that the bus is late and Claude is late to school.
ii) 0.125 = 12.5% probability that Claude is late to school.
iii) Claude should expect to be late for 7 days.
Step-by-step explanation:
i) Calculate the probability that the bus is late and Claude is late to school.
0.1 probability that the bus is late.
If the bus is late, 0.8 probability that Claude is late to school. So
[tex]p = 0.1*0.8 = 0.08[/tex]
0.08 = 8% probability that the bus is late and Claude is late to school.
ii) Calculate the probability that Claude is late to school.
8%(when the bus is late) plus 0.05 of 1 - 0.01 = 0.9. So
[tex]p = 0.08 + 0.05*0.9 = 0.08 + 0.045 = 0.125[/tex]
0.125 = 12.5% probability that Claude is late to school.
iii) The school term lasts 56 days. How many days would Claude expect to be late?
12.5% of 56. So
0.125*56 = 7
Claude should expect to be late for 7 days.

An urban planner examines police-report data for many cities and towns and discovers that cities with professional football teams tend to have higher numbers of reported small crimes, such as burglary.
Which statement best explains the effect of confounding in this relationship?
A.) The football teams are a direct cause of increased small crimes.
B.) In cities without football teams, the small crimes often go unreported.
C.) Cities without football teams most likely have lower rates of reported small crimes.
D.) Cities with football teams tend to be large, which means they have more reported small crimes.
Answer: The answer is D
Step-by-step explanation:
Answer:
D) Cities with football teams tend to be large, which means they have more reported small crimes.
Step-by-step explanation:
Confounding refers to the phenomenon in which an apparent relationship between two variables is actually caused by the influence of a third, confounding variable. In this case, it is possible that the relationship between the presence of a football team and the number of reported small crimes is confounded by the size of the city. It is possible that cities with football teams tend to be larger, and larger cities generally have more reported small crimes, regardless of whether they have a football team. This could explain the apparent relationship between football teams and small crimes. It is important for researchers to consider and control for potential confounding variables in order to accurately interpret the relationships between variables in their study.

Mai made $216 for 18 hours of work.
At the same rate, how many hours would she have to work to make $96?
Answer:
8 hours
Step-by-step explanation:
216 ÷ 18 =12 that means Mai gets paid $12 an hour so take the $96 and ÷ by 12 and you get 8 hours
Answer:
Step-by-step explanation:
First you do 216 divided by 18 which is 12.
Now we know she makes 12 dollars an hour.
Next you divide 96 by 12 because that's how much Mai makes in an hour. 96 divided by 12 is 8 so she would have to 8 hours in order to make 96 dollars.

Find the area of each shaded region each outer polygon is regular
See the picture
Answer:
Area of the shaded region = 3.46 square units
Step-by-step explanation:
Measure of the interior angle of a regular polygon = [tex]\frac{(n - 2)\times180}{n}[/tex]
From the picture attached,
Number of sides of the given polygon 'n' = 6
Interior angle (∠BAF) of the given polygon = [tex]\frac{(6 - 2)\times 180}{6}[/tex]
= 120°
Measure of ∠BAC = [tex]\frac{120}{4}[/tex]
= 30°
Now we apply sine rule in ΔAGB,
sin(30°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{BG}{AB}[/tex]
BG = AB[sin(30°)]
= [tex]2\times \frac{1}{2}[/tex]
= 1
By applying cosine rule in ΔABG,
cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{AG}{AB}[/tex]
AG = AB[cos(30°)]
= [tex]2\times \frac{\sqrt{3} }{2}[/tex]
= [tex]\sqrt{3}[/tex]
AC = 2(AG)
= 2√3
Area of ΔABC = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(AC)(BG)[/tex]
= [tex]\frac{1}{2}(2\sqrt{3} )(1)[/tex]
= [tex]\sqrt{3}[/tex]
Area of the shaded region = Area of ΔABC + Area of ΔFED
= 2(Area of ΔABC)
= 2√3
= 3.46 square units

Answer:
Step-by-step explanation:
A remote interior angle is one that shares only 1 leg with the exterior angle. Every triangle has 2 remote interior angles for each exterior angle.
<1 is a remote interior angle
81 is 1 remote interior angle
127 is an exterior angle
<1 + 81 = 127 Subtract 81 from both sides
<1 = 127 - 81
<1 = 46

Your friend graphs the function represented by the input-output table. Is your friend correct? Explain your reasoning.
Answer:
Incorrect.
Step-by-step explanation:
My friend is incorrect because the input values was plotted along the y-axis while the output values were plotted along the x-axis, which makes the graph totally incorrect.
The right way to plot the graph is to plot the input-values on the x-axis, while the corresponding output values should be plotted on the y-axis.
