If heights of 3rd graders follow a normal distribution with a mean of 52 inches and a standard deviation of 2. 5 inches, what is the z score of a 3rd grader who is 47 inches tall?.
Z score of a 3rd grader who is 47 inches tall with mean of 52 inches and standard deviation of 2.5 inches is 2
Z- Score give an idea how far a data point is from mean .
z = x- μ / σ where numerator is difference between the random variable and the actual mean dividing by the standard deviation .
Given , x = 47 inches
standard deviation = 2.5 inches
mean = 52 inches
z-score = x- μ / σ
putting all the values ,
z-score = 47 - 52 / 2.5
= -5 / 2.5

and [tex]a_{2} x^{2} +b_{2} x+ c_{2} =0[/tex]
The condition at which these equations will have infinitely many solutions is

The condition at which these equations will have infinitely many solutions is

For, the 26th question, we have
4x +8y = -8
4x +8y +8 = 0
x +2y +2 =0 equation(1)
x =-2y +1
x +2y -1 = 0 equation(2)
On comparing these equations with the general form, we have
[tex]a_{1} = 1, a_{2} =1\\b_{1} = 2, b_{2} = 2\\c_{1} = 2, c_{2} = -1[/tex]
So, [tex]\frac{a_{1} }{a_{2} } =\frac{b_{1} }{b_{2} } \neq \frac{c_{1} }{c_{2} }[/tex]
Thus, this system of equations has no solution.
Now, For the 27th question, we have

2. calculate sell price
58 - 17.4 = 40.6
3. calculate sales tax
7/100 × 40.6 = 2.842
4. calculate total price
sell price + sales tax = 40.6 + 2.842 = 43.442
Explain how you know that <4 and <6 are the same side interior angles
Angles ∠4 and ∠6 are the same side interior angles.
Interior angles are defined as the inner of two angles formed when two sides of a polygon intersect. Any of the four angles are formed when a third line intersects a pair of parallel lines.
If two angles are on opposite sides of a transversal, they are alternate. A transversal is a line that runs parallel to two horizontal lines. The alternate angles are alternate interior angles if they are located between the two parallel lines. The alternate angles are alternate exterior angles if they are located outside of the two parallel lines.
Angles ∠4 and ∠6 are known as alternate interior angles based on the information provided. As a result, you have the following options:
They are located on opposing sides of the transversal.
They are located between the two lines crossed by the transversal.
Therefore Angles ∠4 and ∠6 are the same side interior angles.

A continuous function that has a domain of [-3, 4] will include all the values as -3,-2,-1,-0,-1,-2,3,4
What do you mean by continuous function?
In mathematics, a continuous function is one where a continuous variation of the argument results in a continuous variation of the function's value (i.e., a change without a leap). This indicates that there aren't any discontinuities, or sudden changes in value. More specifically, a function is continuous if it is possible to guarantee that its value will not vary significantly even with arbitrarily tiny changes to its parameter. Any function that is not continuous is said to be discontinuous.
It is given that a continuous function has a domain of [-3,4]
According to the definition of closed interval,
[-3,4] will contain all the elements between them and including them.
Therefore, [-3,4] will contain elements as -3,-2,-1,-0,-1,-2,3,4
Hence, a continuous function that has a domain of [-3, 4] will include all the values as -3,-2,-1,-0,-1,-2,3,4

The area of the circular table is 1075.21 square inches.
Jada has a table. The table is circular in shape. She paints the table. The diameter of the circular table is 37 inches. We need to find out the area of the table. We will, first of all, find the radius of the circular table. Let the radius and the area of the table be represented by the variables "r" and "A", respectively.
The radius of a circle is equal to half its diameter.
r = 37/2
r = 18.5 inches
To find the area of the table, we will use the formula for the area of a circle.
A = πr²
A = π(18.5)²
A = 1075.21

ΔABC is not a right angled triangle.
What is right angled triangle?
A right-angle triangle is one that has angles between its two sides that equal 90 degrees.
Main Body:
First let's find the length of the last side. We can do this by adding AB and BC together, then subtracting this amount from the perimeter of Triangle ABC, 22 cm.
ABC - (AB + BC) ⇒ 22 - (8 + 5)
=22 - 13 = 9 cm
The hypotenuse is always the longest side of a triangle, so we know that the side we figured out is the hypotenuse. Now we can use the Pythagorean Theorem to see whether the triangle is a right triangle.
Pythagorean Theorem: a² + b² = c², where a and b are legs and c is the hypotenuse.
If a² + b² do equal c², then the triangle is a right triangle.
⇒8² + 5² = 9²
⇒64 + 25 = 81
⇒89 > 81
Therefore triangle is not a right triangle, but we know that it is obtuse since a and b together are longer than c.

suppose you are standing such that a 63-foot tree is directly between you and the sun. if you are standing 240 feet away from the tree and the tree casts a 270-foot shadow, how tall could you be and still be completely in the shadow of the tree?
You could stand at 7 feet and still be completely in the shadow of the tree.
What is the property of a similar triangle?
Two triangles are similar if their corresponding angles are equal and their corresponding sides are within the same ratio (or proportion).
Given
You are standing such that a 63-foot tree is directly between you and the sun.
If you are standing 240 feet away from the tree and the tree casts a 270-foot shadow.
BC to be the height of the tree and DE to be the height of how tall you could be and still be completely in the shadow of the tree.
∠D = ∠B = 90 degrees
Therefore,
By the similar triangle property;
DE/BC = AD/AC
x/63 = (270-240)/270
x/63=30/270=0.11
x=63*0.11 = 7
Hence, you could stand at 7 feet and still be completely in the shadow of the tree.

What is the equation of the line that passes through the points (5,3) and
(5,-2)?
Answer:
x = 5
Step-by-step explanation:
I'm going to assume that this is asking you to graph in Slope-Intercept form, but if I am mistaken, comment on my answer and I will happily change it.
Slope-Intercept form:
y = mx + b
You leave y and x as variables, while m and b are to be substituted for slope and y-intercept. y-intercept is when x=0, where a point on a line is on the y axis.
To help you learn, for example, we have an equation is slope-intercept form:
y = 8x + 3
In this case, the slope is 8 and the y intercept is 3 as m is the slope and b is the y-intercept.
The slope is the steepness of the graph. The value of the slope is how much the y-value increases if the x-value increases by 1.
We can find the slope from 2 points using this formula:
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we plug in our points into the formula.
[tex]\frac{-2-3}{5-5}[/tex]
Simplify.
[tex]\frac{-5}{0}[/tex]
Anything divided by 0 is undefined. This means the line we are graphing is completely vertical, known as undefined. We can only get this if the x value stays the same no matter what. In this case, the x value stays the same when the y value changes, meaning a undefined slope.
We have a special case here. If the slope is undefined, we do not use y = mx+b. Instead, we use:
x = what the x values of the 2 points are
x values of both points: 5
x = 5
