Answer:
The length of the legs of the triangle is 8 units.
Step-by-step explanation:
45-45-90 triangle
A 45-45-90 triangle is a special case of a right triangle in which both legs l have the same value and the hypothenuse is h. By the Pythagorean Theorem:
[tex]2l^2 = h^2[/tex]
Hypothenuse of 8 V2
This means that [tex]h = 8\sqrt{2}[/tex]
So
[tex]2l^2 = h^2[/tex]
[tex]2l^2 = (8\sqrt{2})^2[/tex]
[tex]2l^2 = 64*2[/tex]
[tex]l^2 = 64[/tex]
[tex]l = \sqrt{64}[/tex]
[tex]l = 8[/tex]
The length of the legs of the triangle is 8 units.
Find the area of the circle. Round your answer to the nearest hundredth. 3 in
Answer:
28.27 or 28 rounded up.
Answer:
7.07 in²
Step-by-step explanation:
Diameter = 3 in ( shown in figure )
Radius = 1/2( diameter) = 1/2 (3) = 1.5 in
Area of a circle = πr²
Area = (3.14)(1.5)²
Area = (3.14)(2.25)
Area = 7.065 in
Area = 7.07 in² ( round off)

Emergency rooms have reason to suspect that visits increase on the weekends. A recent report indicates that Monday through Thursday represent 10% per day of the weekly total visits while Friday accounts for 15%, Saturday 25% and Sunday 20%. If your ER has the following pattern, Monday, 120, Tuesday, 130, Wednesday 110, Thursday 95, Friday 160, Saturday 280 and Sunday 105.
Does your facility have the same pattern as the recent report at the 10% level?
1. Yes
2. No
Answer:
i think i am pretty sure its a yes
No, the facility dose not have the exact pattern as the recent report at the 10% level.
What is Chi squared test of hypothesis?To determine if the Facility have the same pattern,
By using Chi squared test for Goodness of fit state the hypothesis
[tex]$H_{0}[/tex] : μ = same pattern
[tex]$H_{a}[/tex] : μ ≠ same pattern
Expected frequency (E) = proportion [tex]*[/tex] summation of frequency
summation of frequency = 1000
degree of freedom [tex]= 7 - 1 = 6[/tex]
Calculate the expected frequency (E) ,(O-E)²/E.
Given that the observed frequency and expected proportion exists given
For Monday
expected frequency = proportion [tex]*[/tex] frequency = 0.1 [tex]*[/tex] 1000 = 100
(O-E)²/E. = ( 120 - 100 )² / 100 = 4.0.
observed frequency (O), expected frequency (E)
For Tuesday
E = 0.1 [tex]*[/tex] 1000 = 100
(O-E)²/E = ( 130 - 100 )² / 100 = 9.0
For Wednesday through Sunday
Then perform Chi-squared test
X² = Σ(O-E)²/E = 63.642
∝ = 0.1
df = 6
hence P-value = 0.000 ( = chi sq dist rt(test-stat,df)
since P-value < ∝ ; we will fail to reject Ha hence we reject [tex]$H_{0}[/tex].

Step-by-step explanation:
which option has like terms?
a.2x^2 and 4y^2
b.xy and yz
c.3x and and 7x
Answer:
C) 3x and 7x
Step-by-step explanation:
Both terms in C have the same variable in which you can combine the terms to make 1. The other ones don't.
Answer:
c. 3x and 7x
Step-by-step explanation:
We have three pairs of two terms and are asked to determine which option has "like terms."
Like terms are two numbers with variables that are the same.
With this information, we can determine which is and which isn't like terms.
a. 2x^2 and 4y^2 are incorrect because the variables within the number do not match, 2x^2 and 4y^2.
b. xy and yz are incorrect because the variables also do not match, xy and yz.
c. is correct because the variables within the two numbers are the same. 3x and 7x.
Solve 7x- c = k for x
Answer:
D
Step-by-step explanation:
I know the answer is D because I set the equation to be equal to x.
First, I added c to both sides. The equation looked like: 7x=k+c
Then, I divided 7 on both sides, so x would be by itself. The equation looked like x=k+c/7
In conclusion, the answer is D. x=k+c/7

Which of the following statements best describes the diagram below?
a. The intersection of two planes is a line.
b. The intersection of two points is a line.
C. Two points can be contained in two planes.
d. Two points can intersect at two planes.
The statement first “The intersection of two planes is a line." option (a) is correct.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have two planes, Y and Z intersecting each other.
The intersection of two lines is a point.
As we know, if the two planes intersect each other, the intersection will be a line.
If planes are parallel then there will no intersection.
Thus, the statement first “The intersection of two planes is a line." option (a) is correct.

Find the value for x.
Answer:
28.5
Step-by-step explanation:
The sum of the interior angles in a triangle is equal to 180
102 + x + 6 + x + 15 = 180
123 + 2x = 180 subtract 123 from both sides
2x = 57 divide both sides by 2
x = 28.5
An account is open with initial deposit of $5500 and earn 2.5% interest compounded annually. What will the account be worth in 10 years
Answer:
FV= $7,040.46
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $5,500
Number of periods (n)= 10 years
Interest rate (i)= 2.5%
To calculate the future value (FV), we need to use the following formula:
FV= PV*(1 + i)^n
FV= 5,500*(1.025^10)
FV= $7,040.46
