A 6th-grade class did a weekend fitness challenge.
Each student set a goal of `75` minutes of fitness.
Amanda exercised for `78` minutes.
What percent of the goal did she achieve?
Answers
Using percentages we can conclude that Amanda achieved 77.34% of her goal.
What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics.
Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it.
A % is a number without dimensions and without a standard measurement.
For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).
So, percent of goals Amanda achieved:
She exercised for 58 minutes.
Then,
58/75 * 100
77.34%
Therefore, using percentages we can conclude that Amanda achieved 77.34% of her goal.

What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The equation is given below.
[tex]\rm 9^y = 3*6*27*4*81*2[/tex]
Simplify the equation, then the value of the variable 'y' will be given as,
[tex]\rm 9^y = 3*6*27*4*81*2\\\\9^y = 314,928[/tex]

13.5%
135% please answer this question. just answer me
Answers
The percentage value of 13.5 is 135%
Option D is the correct answer.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
1.35
We will multiply 100 to get the percentage.
Now,
1.35
= 135/100 x 100
= 135%
Thus,
135% is the percentage value of 1.35.
Option D is the correct answer.

The value of c is a real solution to the equation [tex]4x^{2}-8x +c[/tex] = 0 is 4
What are Real mathematical solutions ?In algebra, a "real solution" is any answer to an equation that is a real number.
There is just one true solution where discriminant b2 - 4ac equals zero. The equation x2 + 2x + 1 = 0 has one solution, x = -1.
Depending on whether the discriminant is positive, zero, or negative, there are many answers to the quadratic equation that has been presented.
A positive discriminant indicates that the quadratic has two distinct real number solutions.
A discriminant of zero indicates that the quadratic equation has a repeating real number solution.
The quadratic equation given is
[tex]4x^{2}-8x +c[/tex] = 0
For real solution
Discriminant = 0
[tex]b^{2}-4ac[/tex] = 0

Answer:
y = 3x + 72
Step-by-step explanation:
To solve for y, we can rearrange the equation to the form y = 3x + b, where b is a constant. To do this, we move the -9y to the left side of the equation and the 3x to the right side, which gives us -9y - 3x = 81. We can then divide both sides by -9, which gives us y = 3x + 72.

Step-by-step explanation:
Multiply both sides of the equation by 2, which gives us 7 ≥ 2.8x. Swap the sides so all variables on on the left. Divide both sides by 2.8, which gives us the fraction 7/2.8. Multiply both numbers by 10 to get 70/28. Reduce to lowest terms.
7/2 ≥ 1.4x
Swap the sides of the inequality and flip the inequality sign
1.4x ≤ 7/2
Divide both sides of the inequality by 1.4
Thus, x ≤ 5/2 is rhe answer.

Explain why having a significant linear correlation does not imply causality. Give an example to support your answer.
Answers
Correlation may not always indicate causality shown below.
What do you mean by corelation and causation?
We can determine how strongly a pair of variables are linearly associated and change together using the statistical technique of correlation. It only states that there is a relationship; it doesn't explain why or how it came to be. Correlation goes one step farther than causality. It states that any change in one variable's value will result in a change in another variable's value, or that one variable causes the occurrence of another. It also goes by the name "cause and effect."
may not always indicate causality. with a well-known instance.
In New York, ice cream sales and homicide rates are associated (Study)
The frequency of homicides fluctuates along with ice cream sales. Does ice cream consumption result in deaths of people?
No. The mere correlation of two events does not imply causation.
Since correlation does not imply causation in our example, ice cream is not to blame for any fatalities.
There are occasionally some unspoken aspects that are somehow connected. Weather is the underlying factor that drives both ice cream sales and homicide rates, as in our example. The increase in ice cream sales and killings is actually a result of the weather.
Therefore, significant linear correlation does not imply causality.

Answer:
x < 4 or 6 < x
Step-by-step explanation:
You want the compound inequality that describes the number line graph with open circles at 4 and 6, and shading everywhere except between them.
InequalitiesThe left line segment has all values less than 4 shaded. The corresponding inequality is ...
x < 4
The right line segment has all values greater than 6 shaded. The corresponding inequality is ...
x > 6
These do no overlap, so the compound inequality uses "or" to combine them:
x < 4 or x > 6
__
Additional comment
Sometimes it is helpful to have the relationship between the shading and the limit values a little more obvious in the inequality. That will be the case if you always use left-pointing inequality symbols: < or ≤. By writing the compound inequality as ...
x < 4 or 6 < x
we see that shading is outside (left or right of) the interval [4, 6].
The symbol without the "or equal to" bar is used when the circle is an open circle. A filled dot would signify the limit value is part of the interval of interest, and the ≤ (or ≥) symbol would be used.
