Answer:
0.48911
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score, = 27.21 Ib
μ is the population mean = 26.86 lb
σ is the population standard deviation. = 12.82 lb
z = 0.027301
Probability value from Z-Table:
P(x<27.21) = 0.51089
P(x>27.21) = 1 - P(x<27.21) = 0.48911

If Ill m, solve for x and y.
(7y - 20" (5x - 38)
(3x - 4)
Answer:
Solve for x = 17
Solve for y = 9
The value of x and y from the figure are 17 and 7 respectively
From the given diagram, we are told that I ll m, hence:
5x - 38 = 3x - 4 (alternate interior angle)Get the value of x
5x-3x = -4 + 38
2x = 34
x = 34/2
x = 17
Also from the triangle:
7y - 20 + 5x - 38 = 90
7y + 5x -58 = 90
7y + 5(17) = 90 + 58
7y + 85= 148
7y = 148 - 85
7y = 63
y = 63/7
y = 9
Hence the value of x and y from the figure are 17 and 7 respectively

Which trigonometric functions have the same maximum value?
This is a list of trigonometric functions with the same maximum value:
(A) y = arcsinx and y = cos x
What are trigonometric functions?
The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths.
They are extensively employed in all fields of geometry-related study, including geodesy, solid mechanics, celestial mechanics, and many others.
There are six popular trigonometric functions for an angle.
Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).
So, the following equations give us the following maximum values:
arcsinx = -1 to 1
arccosx = -1 to 1
arctanx = -pi/2 to pi/2
arcsecx = ∞
Arcsinx and Arccosx are trigonometric functions that have the same maximum value.
Therefore, this is a list of trigonometric functions with the same maximum value:

The price of a gallon of apple cider is $7.00. The price
of eight 4.23 ounce juice boxes is $2.39.
Peter wants to have at least a gallon of either only cider
or only juice. Which product is the better deal?
Answer:
Apple Cider is the better deal.
Step-by-step explanation:
1 gallon is 128 ounces.
8 times 4.23 is 33.84. So each purchase is 33.84 ounces. If you multiply 33.84 ounces by 4 you get 135.36. (I did 4 because 3 would be too little to make a gallon).
After that you need to multiply 2.39 and 4. You need to do this because it will tell you the cost. That will come out to 9.56$.
So, that is why the apple cider is a better deal, because it is 7$ and the other would be 9.56$.
Hope this helps :-)

If one root of the equation x^2 + 5x + k = 0 is -2, what is the value of k?
Answer:
k = 6
Step-by-step explanation:
given x = - 2 is a root then substitute x = 2 into the equation
(- 2)² + 5(- 2) + k = 0
4 - 10 + k = 0
- 6 + k = 0 ( add 6 to both sides )
k = 6
Answer:
k = 6
Step-by-step explanation:
since x = - 2 put x = 2 into the equation
(- 2)² + 5(- 2) + k = 0
4 - 10 + k = 0
-6 + k = 0
+6 +6
k = 6

A planting bed contains 0.75 tons of soil. A landscaper will apply fertilizer to the bed. The directions say to apply 1 ounce of fertilizer for every 100 pounds of soil.
How many ounces of fertilizer should the landscaper apply?
Answer:
15 ounces
Step-by-step explanation:
0.75 tons is equal to 0.75 * 2000, or 1500, pounds (1 ton is 2000 pounds). Let x represent the number of ounces of fertilizer that should be applied. Set up a proportion:
[tex] \ \frac{1}{100} = \frac{x}{1500} [/tex]
Solving this for x, we have x = 15. So the landscaper should apply 15 ounces of fertilizer.

96 in² I think
Make the triangles into a rectangle, find the area and add it to the original square
Answer: 96 in²
Step-by-step explanation: The parallelogram is comprised of two triangles and one square. You could solve this one of two ways.
1) Find the area of the total parallelogram. The area is b*h, where b is the base and h is the height. The base will ALWAYS be the sum of whatever is on the bottom. In this model, we have 4" and 8", meaning b=12". Now, the height is 8" as seen by the vertical line connecting the top and bottom of the figure. 12 times 8 is 96 inches squared.
2) Find the area of the square and two triangles. The area of a triangle is 1/2*b*h, where b is the base (4") and h is the height (8"). Seeing as we have two triangles, we can do this twice, getting 0.5*4*8 + 0.5*4*8 (1/2 is the same as 0.5 btw). 32 inches squared is for the two triangles. Finally, you need to find the square. To review, the area of a square is s^2, so 8*8 is 64. 64+32 is 96 inches squared.

Based on the data in two-way frequency table, "being in high school" and "gpa above 3.0" are not independent events.
What is conditional probability?The conditional probability is the happening of an event, when the probability of occurring of other event is given.
A two-way frequency table shows grades for students in college and students in high school.
Let H represent being in high school and G represent the GPA above 3.0. To be an independent event, they must be,
[tex]P(H|G)=P(H)[/tex]
The conditional probability of event H, given that the G is occurred, can be calculated as,
[tex]P(H|G)=\dfrac{14}{40}\\P(H|G)=0.35[/tex]
Total students below 3.0 GPA are 60 and the total number of student are 100. Thus, the probability of being in high school is
[tex]P(H)=\dfrac{60}{100}\\P(H)=0.6[/tex]
Here, conditional probability [tex]P(H|G)[/tex] is not equal to the probability of being in high school.
Hence, based on the data in two-way frequency table, "being in high school" and "gpa above 3.0" are not independent events.

Only 3/5 of the University students wanted to become math teachers if 3500 did not want to become math teachers how many university students were there?”
Answer:
8750
Explanation:
There are 5/5 math teachers in the university. 3/5 of them did not want to become math teachers which means 2/5 of the math teachers is equal to 3500.
3500=2/5
divide 3500 by 2 to get 1/5 of the math teachers.
3550/2=1750
1750 is 1/5 of the math teachers.
multiply 1750 by 5 to get 5/5 of the math teachers
1750*5= 8750

The radius of a circle is 4 inches. What is the circle's circumference?
Answer:
8π inches or approximately 25.12 inches

Answer:
See below.
Step-by-step explanation:
Hi there!
We are given a circle, and inside that circle, we know that the radius of that circle is 4 inches
We want to find the circumference of the circle.
The circumference (C) is essentially the perimeter of a circle; the formula for the circumference of a circle is 2πr (r is the radius, π is pi)
Since we know the radius, we can substitute that value into the formula
C=2πr, r=4
C=2π*4
C=8π
If you need the answer in terms of pi, then the answer is 8π inches. However, if you need a number, then substitute an approximation for π, which will usually be 3.14 or 22/7
Using 3.14 for example,
C=8*3.14=25.12 inches
Using 22/7 meanwhile,
C=8*22/7=25.14 inches (rounded to the nearest hundredth)
So the answer is either 8π inches, 25.12 inches, or 25.14 inches (depending on how you need it approximated)
Either way, hope this helps!

2. A Cylindrical hot water tank is closed at both ends. The radius of the tank is 0.5m and the height is 0.75.calculate i. The volume of the Cylinder it. The total surface area of the tank (take π =22 out of 7
Answer:
Volume = 0.59 m³
Surface Area = 3.93 m²
Step-by-step explanation:
Given :-
- Radius = 0.5 cm
- Height = 0.75 cm
To Find :-
- Volume
- Surface Area
Solving :-
Volume = πr²h
= 22/7 x (0.5)² x 0.75
= 22/7 x 1/4 x 3/4
= 66/112
= 33/56 m³
= 0.59 m³
Surface Area = 2πr (r + h)
= 2 x 22/7 x 0.5 (0.5 + 0.75)
= 22/7 x 5/4
= 110/28
= 55/14 m²
= 3.93 m²
Solution :-
Volume = 0.59 m³
Surface Area = 3.93 m²
Answer:
1. Formula for volume of a cylinder;
V = πr^2h
where pi is 3.14 or 22/7, r is the radius(0.5) which is squared, and h is the height
plug in the actual values;
V = πr^2h
V = 3.14 * 0.5^2 * 0.75
V = 3.14 * 0.25 * 0.75
V = 0.785 x 0.75
V = 0.58875^3 meters or 0.59^3 meters, is the volume. (round to whatever place they covet)
2. Formula for surface area of a cylinder;
SA = 2πr(r + h)
Plug in the actual values:
SA = 2πr(r + h)
SA = 2 x 3.14 x 0.5(0.5 + 0.75)
SA = 2 x 3.14 x 0.5(1.25)
SA = 2 x 3.14 x 0.625
SA = 3.925 meters or 3.93 meters is the surface area.
