A normal distribution has a mean of 75 and a standard deviation of 15.
Determine the z-score for the data value of 85.
0.67
1) Given that we've got the following data:
[tex]\mu=75,\sigma=15,X=85[/tex]We can plug them all together into the Z score formula:
[tex]Z=\frac{X-\mu}{\sigma}=\frac{85-75}{15}=\frac{10}{15}\approx0.67[/tex]Thus, the Z-score is 0.67

Line segment EF has endpoints at (2,-4) and (5,-9)
If ST is congruent to EF and has one endpoint at (4,9), which of the following points could be the second endpoint?
A.(-4,-3)
B.(-1,12)
C.(22,-3)
D.(-4,11)
Please show work so I can understand how to do it.
The second endpoint of ST is B(-1,12).
It is given in the question that:-
Endpoints of line segment EF are (2,-4) and (5,-9).
One of the endpoint of ST is (4,9).
We have to find the second endpoint of ST.
As both of the line segments are congruent hence, the length of each line segment will be same.
We can find the length of the line segment EF using the distance formula.
Length of the line segment EF :-
[tex]\sqrt{(-9-(-4)^2+(5-2)^2}=\sqrt{(-9+4)^2+3^2}=\sqrt{25+9}=\sqrt{34} units[/tex]
Hence, length of the line segment ST should also be the same.
We can check that from the options and get B(-1,12) as the answer.

What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
We know that ,
Trigonometric identities
sin²θ+cos²θ=1
so 1-cos²θ= sin²θ
sec²θ+tan²θ=1
1-sec²θ=tan²θ
So √ 1-cos²θ/1-sec²θ
√ 1-cos²θ/1-sec²θ=√sin²θ/tan²θ
The square root will get cancelled
=sinθ/tanθ
=sinθ/sinθ/cosθ (because tanθ=sinθ/cosθ)
=cosθ
Hence √ 1-cos²θ/1-sec²θ=cosθ, cosθ is the simplified form of √ 1-cos²θ/1-sec²θ

If a triangle has 2 sides measuring 10 and 64 then the 3rd side must be less than what value
Answer:
It must be less than 180º.
Step-by-step explanation:
A triangle always adds up to 180º which then means that since two angles have already been stated that means the total of those two angles is 74º which you subtract from 180º to get 106º which is the measure of the third angle.

Which is the domain and range of the parabola with the equation… Thanks
Okay, here we have this:
Considering the provided equation of the parabola, we are going to find the requested domain and range, so we obtain the following:
Domain: Corresponds to all the values that x can take in the function. Given that in this case no value of x indeterminates the function, and that x can take any value, then its domain will be: (-∞, ∞).
Range: Corresponds to all the values that the dependent variable can take. In this case, since it is a parabola of the form ax^2+bx+c, and that a is less than or greater than 0, its range will be all values greater than or equal to its y-coordinate of the vertex, which for this case is (5, -15). So its range is: [-15, ∞).
Therefore finally we obtain that the correct answer is the fourth option.
Which region has a population density less than 60 animals per square mile
Explanation
We will have to find the population density of each of the regions
To get the population density, we will have to divide the population of each region and then divide by the area of the of each region
For part A
[tex]Area=\frac{1}{2}\times40\times35=700mi^2[/tex]The population density of region A is
[tex]\frac{42500}{700}=60.71\text{ animals per square miles}[/tex]For region B
The area of region B is
[tex]\frac{1}{2}\times50\times38=950mi^2[/tex]The population density of region B is
[tex]\frac{60800}{950}=64\text{ animals per square miles}[/tex]For region C
[tex]area=\frac{1}{2}\times42\times49=1029mi^2[/tex]The population density of region C
[tex]\frac{57300}{1029}=55\text{ animals per square mile}[/tex]Thus, we can observe that Region C has a population density lower than 60 animals per square miles

Cost of Goods Sold: $
Suggested selling price: $
The cost of Goods Sold will be $93.5
What is Addition?
A process of combining two or more numbers is called addition.
Given that;
The Cost of Goods Sold for one Holiday Basket:
1 basket = $24.00 per dozen
2 lbs. Cheddar cheese = $1.50 per pound
1 canned ham = $60.00 per dozen
3 jars of jelly = $1.00 each
6 oranges = $2.00 per dozen
1 box crackers = 2.00 per box
Cellophane wrap = $.50 each
Now,
Since, Each basket has only one of each item in it.
So, The total cost = $24 + $1.50 x 2 + $60 + $1 x 3 + $1 + $2 + $0.50
= $93.5

Part B) Option c
What is a speed, exactly?
Velocity is the rate and direction of an object's movement, whereas speed is the time rate at which an object is moving along a path.
Given:
In 3 hours and 186 miles, Car X goes.
To find the equation of the line that represents the relationship between distance and time, perform the following steps:
Step 1: Assume that car X traveled a total distance of y miles and traveled that amount in x minutes.
Step 2: The speed is determined by the distance to time ratio.
speed = distance / time
Step 3: Add the distance and time values to the equation above.
Speed = y/x —— (1) (1)
Step 4 - Based on the provided information, the speed is determined by:
speed = 186/3 = 62
Step 5: Adding the speed value to the equation (1).
y/x = 62
y = 62x
(Y = 62x) is the equation of the line that depicts the relationship between space and time.

Sandra will be paid 72.30 dollars for babysitting for 12 hours.
Explanation
We are told that Sandra earned 60.25 dollars babysitting 10 hours.
If she babysits at the same rate, we are asked to calculate the amount she would earn if she babysits for 12 hours.
Let the amount Sandra is paid for babysitting for 12 hours be x dollars
10 hours = 60.25 dollars
12 hours = x dollars
We can write a mathematical relationship by cross multiplying
10 × x = 12 × 60.25
10x = 723
Divide both sides by 10
(10x/10) = (723/10)
x = 72.3 dollars

1. (5 points) The arc of a football thrown by Patrick Mahomes is modeled by the equation h=-16t2 + 36t + 6, where h = the height of the ball and t = the time in seconds. Will the ball reach a height of 24 feet?
In order to determine if the ball reaches the 24 ft, replace h = 24 and solve the quadratic equation. If the solutions are real, then, the ball does reach 24ft.
Proceed as follow:
h = 16t² + 36t + 6
24 = 16t² + 36t + 6
16t² + 36t + 6 - 24 = 0
16t² + 36t - 18 = 0

[tex]t=\frac{-b\pm\sqrt[]{b^{2}-4ac}}{2a}[/tex]In this case, a = 16, b = 36 and c = -18
[tex]\begin{gathered} t=\frac{-36\pm\sqrt[]{(36)^{2}-4(16)(-18)}}{2(16)} \\ t=\frac{-36\pm49.47}{32} \\ t_1=-2.67 \\ t_2=\text{0}.42 \end{gathered}[/tex]negative times do not have physical meanning, then, the available solution is
