The grades on a language midterm at Oak Academy are roughly symmetric with = 67 and 0 = 2.5. Ishaan scored 70 on the exam. Find the z-score for Ishaan's exam grade. Round to the nearest tenth.
Answer: 1.2
Step-by-step explanation:
Let X denotes the grades on a language midterm at Oak Academy.
As per given ,
X follows normal distribution ( because it has symmetric graph)
[tex]\mu=67,\ \ \ \ \sigma= 2.5[/tex]
Formula for z : [tex]z=\dfrac{X-\mu}{\sigma}[/tex]
For X = 70, we have
[tex]z=\dfrac{70-67}{2.5}=\dfrac{3}{2.5}=1.2[/tex]
Hence, the z-score for Ishaan's exam grade = 1.2
z-scores are the corresponding standard normal variate's values for normal variates' values. The z-score for Ishaan's grade is 1.2
How to get the z scores?If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.
If we have
[tex]X \sim N(\mu, \sigma)[/tex]
(X is following normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] )
then it can be converted to standard normal distribution as
[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]
(Know the fact that in continuous distribution, probability of a single point is 0, so we can write
[tex]P(Z \leq z) = P(Z < z) )[/tex]
Also, know that if we look for Z = z in z tables, the p-value we get is
[tex]P(Z \leq z) = \rm p \: value[/tex]
For the given case, if we suppose the random variable X's values as scores of the grades on given language midterm at Oak Academy, then, as it is symmetric around value 67, with σ = 2.5, thus,
[tex]X = N(\mu = 67, \sigma = 2.5)[/tex]
Its given that Ishaan scored X = 70
The standard normal variate conversion of X is given by:
[tex]Z = \dfrac{X- \mu}{\sigma} = \dfrac{X - 67}{2.5}[/tex]
Thus, z-scores for Ishaan's score is: [tex]Z = \dfrac{70 - 67}{2.5} = \dfrac{3}{2.5} = 1.2[/tex]

Find AC+CB.
Find BC−AC.
Find AB.
Find CA+BC.
Question 2
The "different" answer is
. The "same" answer is
.
Answer:
Step-by-step explanation:
Question 1
BC - AC and AB will provide different answers when compared to AC + CB and CA + BC. This is because AC means A multiplied by C (AC) or C multiplied by A (CA); thus means AC and CA are the same. Also, CB means C multiplied by B (CB) or B multiplied by C (BC); thus means CB and BC are the same.
Hence, Finding AC + CB will provide the same answer as finding CA + BC
However, finding BC - AC will provide different answer to finding AB because BC - AC means the multiplication of A and C is subtracted from the multiplication of B and C - the answer thereof will most likely be different from the multiplication of just A and B.
Question 2

A milk truck delivers 396 dozen gallons of milk to stores in 1 day. Write and solve an equation to find n, the number of gallons of milk the milk truck delivers in 1 day. nothing
Answer:
[tex]n = 4752 \ gallons[/tex]
Step-by-step explanation:
Given
Delivery: 396 dozens gallons in a day
Required
Determine the number of gallons in a day
From the question above, we understand that:
[tex]n = 396\ dozens\ gallon[/tex]
From unit conversion:
[tex]1\ dozen = 12[/tex]
So:
[tex]n = 396\ dozens\ gallon[/tex] becomes
[tex]n = 396 * 12 \ gallon[/tex]
[tex]n = 4752 \ gallons[/tex]
Hence, 4752 gallons of milk is delivered daily

in the circle shown, AB is tangent to circle o at point and OC is a radius
Which relationship is true?
Answer:
A. [tex] \overline{OC} \perp \overline{AB} [/tex]
Step-by-step explanation:
According to tangent theorem, a tangent is formed when the radius of a circle is perpendicular to the line, meeting at a point around the circle, such that the tangent line would be perpendicular to the radius of the circle with a center.
Given that [tex] \overline{AB} [/tex] is a tangent of the circle O, at a point C, and [tex] \overline{OC} [/tex] is a radius, therefore, it follows that:
[tex] \overline{OC} \perp \overline{AB} [/tex].
This means the radius of the circle is perpendicular to the tangent formed at point C.

Step-by-step explanation:
George hiked from the top of a hill to the valley floor. The elevation at the top of the hill is 127 feet above sea level. The valley floor is 52 feet below sea level. George stopped at a rest stop that is at an elevation exactly halfway between the top of the hill and the valley floor. What is the elevation, in feet, of the rest stop? Show your work
Answer:
The elevation of the rest stop is 37.5 feet above sea level.
Step-by-step explanation:
Given that the elevation at the top of the hill is 127 feet above sea level and The valley floor is 52 feet below sea level.
So, the total length from the top of the hill to the valley floor
[tex]l= 127+52 = 179[/tex] feet
So, length of halfway [tex]= l/2=179/2=89.5[/tex] feet ...(i)
Assuming that the stop for rest, the halfway between the top of the hill and the valley floor, is at x feet above sea level.
So, the length between the stop position and the valley floor [tex]= 52 +x[/tex] feet.
As the stop position is at half-way, so by using equation (i), we have,
[tex]52 + x = 89.5 \\\\\Rightarrow x =89.5-52 \\\\[/tex]
[tex]\Rightarrow x=37.5[/tex] feet
Hence, the elevation of the rest stop is 37.5 feet above sea level.

The image point of A after a translation right 1 unit and down 2 units is the point B (9,3). Determine the coordinates of the pre-image point A.
Alright, it went 1 to the right and down 2 times.
So for point B, you calculate the opposite.
Point B goes 1 left while going up by 2.
(9 - 1, 3 + 2) = (8, 5)
Pre-image point A is (8, 5)
The preimage of point A before a translation right 1 unit and down 2 units
is (8, 5).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
Given, The image point of A after a translation right 1 unit and down 2 units is point B (9, 3) so we go exact opposite 1 unit left and 2 units up which is
(- 1, 2).
∴ The pre-image point A is (8, 5).
