Given
Hypotenuse AC= 10
Opposite BC = 8
Required

Whats 4.87 rounded to the nearest tenths
Answer:
4.9
Step-by-step explanation:
Tenths is the number directly after the "." so the 8 in 4.87 is the tenth. Rounding is quite easy, since 7 is bigger than 5 you add 1 to the 8 thus rounding the 4.87 to 4.9
Answer:
4.90
Step-by-step explanation
in 4.87 the 7 hundredth is closer to 4.90 rather than 4.80
Preston teaches at an international school. After reading an article about the distribution of the world's population by continent, he wanted to test if the distribution of students in his school was similar. He collected information about all 320 students in his school. Here are the results:
Preston wants to perform x^2 goodness-of-fit test to determine if these results suggest that the distribution of students doesn't match the reported distribution.
What is the expected count of students from Australia in Preston's group?
Answer:
Since there are 320 students, and Preston expects 0.5% of them to be from Australia, the expected count of students from Australia is 0.005 (320) =1.6
The expected count students from Australia is 1.6.
Step-by-step explanation:
The expected count of students from Australia in Preston's group is equal to 1.6.
What is a goodness-of-fit test?A goodness-of-fit test can be defined as a statistical tool that is used to test if sample data fits into a set of observations or distribution from a given population.
This ultimately implies that, a goodness-of-fit test helps to determine whether on not sample data represents the data that are expected in an actual population.
Given the followin data:
Popuation = 320 students.
Expected percent (Preston's group) = 0.5% = 0.005.
Expect count = 0.005 × 320
Expect count = 1.6.

If x/y =6, y/w =4, and x=36, what is the value of w? (A) 1 2 (B) 3 2 (C) 2 (D) 4 (E) 6
Answer:
w = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{x}{y}[/tex] = 6 and x = 36 , then
[tex]\frac{36}{y}[/tex] = 6 ( multiply both sides by y )
36 = 6y ( divide both sides by 6 (
6 = y
Then
[tex]\frac{y}{w}[/tex] = 4 , that is
[tex]\frac{6}{w}[/tex] = 4 ( multiply both sides by w )
6 = 4w ( divide both sides by 4 )
[tex]\frac{6}{4}[/tex] = w , that is
w = [tex]\frac{3}{2}[/tex]

Write each of these propositions in the form "p if and only if q" in English.
a) If it is hot outside you buy an ice cream cone, and if you buy an ice cream cone it is hot outside.
b) For you to win the contest it is necessary and sufficient that you have the only winning ticket.
c) You get promoted only if you have connections, and you have connections only if you get promoted.
d) If you watch television your mind will decay, and conversely.
e) The trains run late on exactly those days when I take it.
Answer:
The "p if and only if q" statement is equivalent to "q if and only if p", then let's rewrite all the propositions in this way.
a) "If it is hot outside you buy an ice cream cone, and if you buy an ice cream cone it is hot outside."
We can define:
q = is hot outside
p = you buy an ice cream cone
Then we can rewrite this as:
"You buy an ice cream cone if and only if is hot outside"
b) "For you to win the contest it is necessary and sufficient that you have the only winning ticket."
We can define:
p = you winning the contest
q = have the winning ticket
Then we can rewrite (changing some words) this as:
"You will win the contest if and only if you have the winning ticke"
c) "You get promoted only if you have connections, and you have connections only if you get promoted."
We can define:
p = you get promoted
q = you have connections
We can rewrite the proposition as:
"You can get promoted if and only if you have connections"
d) " If you watch television your mind will decay, and conversely."
We can define:
p = you watch television
q = your mind will decay
We can rewrite it as:
"You can watch television if and only if your mind decays"
e) " The trains run late on exactly those days when I take it."
We can define:
p = The train runs late
q = I take it.
We can rewrite the proposition as:
"The train runs late if and only if I take it"

Each fier station hose at the la salle fier station is 25 yards long. The station needs enough fier hoses to reach from any fier hoses to reach from any fier hydrant to the farthest house wich could be up to 230 feet away. What is the minimum number of hoses that the la salle fier station should have.
Answer:
4
Step-by-step explanation:
minimum number of hoses needed = farthest length / length of a hose
convert the length of a hose to feet
1 yards = 3 feet
25 x 3 = 75 feet
230 / 75 = 3.1
4 hoses would be needed
What is the distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3?
Answer:
The distance is [tex]\sqrt{20}[/tex] or [tex]2\sqrt{5}[/tex].
Step-by-step explanation:
Slope of parallel: 2
Slope of perpendicular: -1/2
Pick a point for y =2x + 7. For example (0,7)
Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).
Distance formula [tex]\sqrt{(x_{2}-x_{1} )^{2}+(y_{2} -y_{1})^2 }[/tex]
Insert (0,7) and (4,5)
[tex]\sqrt{(0-4)^{2}+(7-5)^2 }[/tex] = [tex]\sqrt{(-4)^{2}+(2)^2 } = \sqrt{(16)+(4)} } = \sqrt{20} = 2\sqrt{5}[/tex]
The distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3 is [tex]2\sqrt{5}[/tex] and can be determined by using the point-slope form and also by using the distance formula.
Given :
y = 2x + 7y = 2x - 3First, determine the line perpendicular to the line (y = 2x + 7) whosw slope is -1/2 and intersect the line (y = 2x + 7) at point (0,7).
Using the point-slope, the equation of the perpendicular line can be determined.
[tex](y-y_1)=m(x-x_1)[/tex] ---- (1)
where m is the slope and [tex](x_1,y_1)[/tex] is the point on the line.
Now, put the value of known terms in the equation (1).
[tex]y-7=-\dfrac{1}{2}(x-0)[/tex]
y = -0.5x + 7 --- (2)
Now, determine the point of intersection between lines (y = -0.5x + 7) and (y = 2x -3).
Substitute the value of y that is (y = 2x - 3) in equation (y = -0.5x + 7).
2x - 3 = -0.5x + 7
2.5x = 10
x = 4
Now, put the value of x in the equation (y = -0.5x + 7).
y = -0.5(4) + 7
y = 5
Now, the distance between two points is given by the equation:
[tex]\rm D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\rm D = \sqrt{(0-4)^2+(7-5)^2}[/tex]
[tex]\rm D = \sqrt{20}[/tex]
[tex]\rm D = 2\sqrt{5}[/tex]
The distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3 is [tex]2\sqrt{5}[/tex].

If the area of a square is 7.29 square yards, what is the length of one of the sides?
Answer:
2.7
Step-by-step explanation:
Since the shape is a square, just square root its area to get its side's sides.
Square root 7.29:
2^2 is 4, and 3^2 is 9, so we know that the answer is somewhere between 2 and 3
Let's try 2.5:
2.5^2 = 2.5*2.5 = 6.25, not quite
Let's try 2.6:
2.6^2 = 2.6*2.6 = 6.76, still a bit short
Let's try 2.7:
2.7^2 = 2.7*2.7 = 7.29, We have 7.29, so 2.7 is the answer!
