7) Choose the inequality that represents the statement.
The water level will be 10 feet or lower by tomorrow.
Answers
The water level will be 10 feet or lower by tomorrow, the correct inequality for this is x [tex]\leq \\[/tex] 10. Hence, the first option is the correct one.
What is inequality?A connection in mathematics that compares two numbers or other mathematical expressions in an unequal way is known as an inequality. It is most frequently used to compare the sizes of two numbers on the number line. To indicate various sorts of inequalities, a variety of notations are used:
A less than symbol (a < b) indicates that an is less than b.A bigger value than b is indicated by the notation a > b.These relationships are referred to be stringent inequalities since an is either strictly less than or strictly greater than b in these cases.
According to the question,
water will be equal to 10 feet or lower than 10 feet it cannot be greater than 10 feet.
Assume water is represented by x.
For water equal to 10 feet: x = 10 feet and,
For water lower than 10 feet: x < 10 feet.
So, we can write both like this: x [tex]\leq[/tex] 10
This concludes that the first option is correct.

Write the equation of a line that is perpendicular to y = -3 + 6 and that passes through the point
(2,-6).
Answers
Answer:
Perpendicular lines are lines that are at right angles to each other.
For perpendicular lines, the product of their slopes is -1.
[tex]\implies m_2=\dfrac{-1}{m_1}[/tex]
(where [tex]m_1[/tex] and [tex]m_2[/tex] are the slopes of perpendicular lines)
The slope of the given equation is -3. Therefore, to find the slope of the line that is perpendicular:
[tex]m_2=\dfrac{-1}{-3}=\dfrac13[/tex]
Now we have the slope, we can use the point-slope form of a linear equation with [tex]m=\dfrac13[/tex] and [tex](x_1,y_1)=(2,-6)[/tex] to find the equation of the perpendicular line:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-(-6)=\dfrac13(x-2)[/tex]
[tex]\implies y+6=\dfrac13x-\dfrac23[/tex]
[tex]\implies y=\dfrac13x-\dfrac{20}3[/tex]

What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
In the diagram, quadrilateral HIJK is inscribed in circle L.
Now, We know that;
sum of opposite angle are 180 degree.
Hence, We get;
∠H + ∠J = 180
67 + (y - 75) = 180
y - 8 = 180
y = 180 + 8
y = 188
And, We get;
∠I + ∠K = 180°
96 + (x + 83) = 180
x + 179 = 180
x = 180 - 179
x = 1
Thus, The value of variables x and y are,
x = 1 and y = 188

Answers
The formula Sabine should use for calculating the variance and standard deviation for the random sample of bamboo stalks are,
[tex]s^2=\dfrac{(x_1-\overline x)^2(x_2-\overline x)^2...(x_n-\overline x)^2}{n-1}[/tex]
[tex]s=\sqrt{\dfrac{(x_1-\overline x)^2(x_2-\overline x)^2...(x_n-\overline x)^2}{n-1}}[/tex]
What is variance and standard deviation?The variance of the data is the measure of average level by which every point is differed from the mean.
It can be calculated as,
[tex]s^2=\dfrac{(x_1-\overline x)^2(x_2-\overline x)^2...(x_n-\overline x)^2}{n-1}[/tex]
The standard deviation of the data is the half of the difference of the highest value and mean of the data set.
It can be calculated as,
[tex]s=\sqrt{\dfrac{(x_1-\overline x)^2(x_2-\overline x)^2...(x_n-\overline x)^2}{n-1}}[/tex]
Sabine records the daily heights of a random sample of bamboo stalks, in inches.
