WS bisects ∠BWV. m∡BWS = 36°. What is m∡BWV?
a. 72
b. 16
c. 54
d. 144
WS bisects angle BWV, m ∠BWS = 36° , then the measure of angle
m ∠BWV is equal to 72°.
As given in the question,
Measure of given angle :
m ∠BWS =36° ____(1)
let 'x' be the measure of angle BWV
WS bisects angle BWV.
⇒ m ∠BWS= m ∠SWV
⇒ m ∠SWV=36° ____(2)
Also , m ∠BWV is equal to the sum of the measure of ∠ BWS and ∠SWV.
⇒ m ∠BWV =m ∠BWS + m ∠SWV
Substitute the value of m∠ BWS and m ∠SWV from (1) and (2),
⇒ m ∠BWV=36° + 36°
⇒m ∠BWV=72°
Therefore, WS bisects angle BWV, m ∠BWS=36° , then the measure of angle m ∠BWV is equal to 72°.

find x : 5( x + 4 ) - 3^2 = 2^4
Answer:x=1
Step-by-step explanation:
you would have to distribute the 5 into the (x+4)
then it would be
5x+20-3^2=2^4
then do the exponents
5x+20-9+16
then add 9 by both sides
5x+20=25
then subtract 20 on both sides
5x=5
then divide 5 on both sides
x=1
then check your work by putting 1 for x and you get 2^4=16
Answer:
x = 1Step-by-step explanation:
find x :
5( x + 4 ) - 3^2 = 2^4
5x + 20 - 9 = 16
5x = 16 - 20 + 9
5x = 5
x = 5 : 5
x = 1
----------------
check
5(1 + 4) - 3^2 = 2 ^4
25 - 9 = 16

Line ℓ has equation y=7. Find the distance between ℓ and the point j (-5,-1)
The Distance between line ℓ and the point j (-5,-1) is 8units.
The distance between a point PP and a line LL is the shortest distance between PP and LL; it is the minimum length required to move from point PP to a point on LL. In fact, this path of minimum length can be shown to be a line segment perpendicular to LL. The distance d can then be defined as the length of the line segment that has PP as an endpoint and is perpendicular to LL.
We know that the distance d between a point (x1,y1) and a line having equation in form of ax+by+c=0 can be expressed as,
[tex]d = \frac{|ax1+by1+c|}{\sqrt{(a^2+b^2)} }[/tex]
So, we have given that equation of line
y = 7
y-7=0
Point j = (-5,-1)
So, Distance between point j and line = d
d = [tex]\frac{|0(-5)+1(-1)-7|}{\sqrt{(0^2+1^2)} }[/tex]
d = [tex]\frac{8}{\sqrt{1} }[/tex]
d = 8 units
Therefore, The point j is at a distance of 8 units from the line ℓ.

10. A theme park has a ride that is located in half a sphere. The ride goes around the widest part of the sphere, which has a circumference of 514.96 yards. What is the surface area of the sphere? Estimate to the nearest hundredth using 3.14 for pie
The surface area of the sphere is 84453.44 yards².
We are given that:
the ride goes around the widest circle of the sphere whose circumference is = 514.96 yard.
The widest circle of the sphere is the plane contains the sphere's center
The circumference of the widest circle is:
C = 2 π r
where r is radius of the sphere.
The surface area of the sphere is defined as:
A = 4 π r²
where r is radius of the sphere.
So, we get that:
514.96 =2 π r
514.96= 2 × 3.14 × r
r = 514.96 ÷ (2 × 3.14)
r = 514.96 ÷ 6.28
Surface Area A = 4 π r²
A = 4 × 3.14 × (514.96 ÷ 6.28) × (514.96÷ 6.28)
A = 84453.44 yards²
Therefore, we get that, the surface area of the sphere is 84453.44 yards².

you are the newly appointed assistant administrator at a local hospital, and your first project is to investigate the quality of the patient meals put out by the food-service department. you conducted a 10-day survey by submitting a simple questionnaire to the 400 patients with each meal, asking that they simply check off that the meal was either satisfactory or unsatisfactory. for simplicity in this problem, assume that the response was 1,000 returned questionnaires from the 1,200 meals each day. the results are as follows:
Using the z-distribution, the 95% confidence interval for the proportion of unsatisfactory meals is given by:
(0.0553, 0.0647).
What is a confidence interval of proportions?A confidence interval of proportions is given by the following rule:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
The estimate and the sample size of the interval are given as follows:
[tex]\pi = \frac{600}{10000} = 0.06, n = 10000[/tex]
The lower bound of the interval is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.06 - 1.96\sqrt{\frac{0.06(0.94)}{10000}} = 0.0553[/tex]
The upper bound of the interval is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.06 + 1.96\sqrt{\frac{0.06(0.94)}{10000}} = 0.0647[/tex]
Hence the interval in (LCL, UCL) format is:
(0.0553, 0.0647).

Convert 62 miles/hour to feet/second (5280ft-1 mile)
In mathematics, an operation is a function that transforms 0-n operands or parameters into a known output value. The number of operands affects how complicated the operation is. 90.95 feet per second equates to 62 miles per hour.
What is mathematical operation?An operation in mathematics is the function that converts 0–n parameters or operands into definite output value. The complexity of operation depends on how many operands there are.
The operations that are the most frequently studied are binary operations (i.e., operations of the arity 2), which include addition and multiplication, and the unary operations (i.e., operations of the arity 1), which include additive inverse and the multiplicative inverse. A zero-arity operation, also known as nullary operation, is a constant. An illustration of ternary operation, also known as an operation of arity 3, is the mixed product.
Usually, it is considered that arity is constrained. Even so, the infinitary operations are occasionally considered, in which case "normal" finite dimensionality operations are referred to as finiteary operations.
A partial operation is described as being similar to operation but using a partial function in place of a function.

The transformation for Rectangle A which would result in Rectangle B is: A. reflection across the x-axis.
What is a reflection?A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.
In Mathematics, a reflection over the x-axis would maintain the same x-coordinate (10 → 10) while the sign of the y-coordinate changes from positive to negative (4 → -4) . Therefore, a reflection over the x-axis is given by this rule:
(x, y) → (x, -y) = (10, 4) → (10, -4).

What is interval notation in math?
Continuous sets of real numbers can be represented by the integers that bound them using interval notation. When written, intervals resemble ordered pairs in several ways. They don't necessarily indicate a particular point, though. They are intended to serve as a shortened manner of expressing an inequality or system of inequalities.8x-5>=6x-1 or 4+4x<=3x-3
8x-5 ≥6x-1
8x - 5 ≥ 6x - 1

x ≥ 1/2
Therefore, x could be any number less than or equal to 1/2. In interval notation, this looks like
