The shape of the sampling distribution of the proportions is "approximately normal" is the correct answer.
What is the sampling distribution of proportion?"The sampling distribution of proportion measures the proportion of success, i.e. a chance of occurrence of certain events, by dividing the number of successes i.e. chances by the sample size n".
For the given situation,
Total number of random samples = 1000
A map website claims to be available of time = 99.995%
⇒ [tex]0.99[/tex]
Let us assume the website's claim is accurate.
Sample proportions closest to 0.6 would be most common, and sample proportions far from 0.6 in either direction would be progressively less likely. In other words, the shape of the distribution of sample proportion should bulge in the middle and taper at the ends: it should be somewhat normal.
Hence we can conclude that the shape of the sampling distribution of the proportions is "approximately normal" is the correct answer.

Identify a set of parallel lines and a set of perpendicular lines in this image
Answer
It is the first answer.
Step-by-step explanation:
Parallel lines are lines that will never cross each other.
Perpendicular lines are lines that cross each other at 90 degree angles (represented by the box in the corner).
A set of parallel lines and a set of perpendicular lines in this image are; AB║CD, CD ⊥ EF and AB ⊥ EF
How are parallel straight lines related?Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.
Since Parallel lines are lines that will never cross each other.
We know that Perpendicular lines are lines that cross each other at 90 degree angles.
The parallel lines are AB and CD, the perpendicular are AB and EF because the first sets are side by side and the second sets cross each other at a certain point.
Therefore the set of parallel lines and a set of perpendicular lines in this image are; AB║CD, CD ⊥ EF and AB ⊥ EF

Find the value of x *
A) 20
B) 10
C) 15
D) 25
Answer:
B. 10
Step-by-step explanation:
While doing construction O and P are joined then
OQ = OR
<QOR = 80°
<QPR = <QOR /2 ( INSCRIBED ANGLE IS HALF OF THE CENTRAL ANGLE STANDING ON SAME ARC)
<QPR = 80°/2
<QPR = 40°
SO
< QPO = X
<RPO = 30°
<QPO + <RPO = < QPR
X + 30° = 40°
X = 40° - 30°
X = 10°

Step-by-step explanation:
in order for it to be a triangle the angles have to add up to equal 180
5+75+100=180 so its not a
10+80+90=180 so its not b
20+60+100=180 so its not c
45+45+45=135 so its d because the angles dont add up to 180
50+50+80=180 so its not e
Answer:
D
Step-by-step explanation:
To be a triangle, you have to have 180 degrees. if you add up all of the sides, it should give you 180. If it doesn't, it isn't a triangle. I hope that helped! :)

Answer:
4 3/10
Step-by-step explanation:
Solve the system by substitution.
x= -5y - 6
5x – 3y = -2
What’s is the solution?
The value of x is -1 and value of y is -1.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equations are
x+5y=-6...(1)
5x – 3y = -2...(2)
Multiply equation 1 with 5
5x+25y=-30..(3)
Subtract equation 2 and equation 3
5x-3y-5x-25y=-2+30
-28y=28
Divide both sides by 28
y=-1
Now plug in y value in equation 1
x=5-6
x=-1
Hence, the value of x is -1 and value of y is -1.

2. A bag of dog food weighs 40 lb. By weight, 16% of the ingredients is turkey. Find the weight of turkey in the
dog food.
Answer:
Pretty sure it's 6.4 lbs
Step-by-step explanation:
We have to set up a proporion. So ?/40 and 16/100 because 16% of 100. Since we can't cross multiply 100 and ?, we have to cross multiply 16 × 40 = 640. We have 100 leftover, so 640÷100=6.4

a) f (x)=4^x
b) f (x)=(1/4)^-x
c) f (x)=(2/3)^x
d) f (x)= (2.3)^x
e) f (x)=(.8)^x
Option:-
a) f(x) = 4^x is applicable
b) f(x) ={ (1/4)^-x = 4^x }is applicable
c.) f(x) = (2/3)^x is not applicable
d.) f(x) = (2.3)^x is applicable
e.) f(x) = (.8)^x is not applicable
Options (a), (b) and (d) are exponential growth functions.
What is Exponential function?An exponential decay is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier which is less than 1.
By the Exponential decay form,
An exponential decay is in the form: y = abˣ
(a) f (x)=4ˣ is applicable as 4>1
(b) f (x)=(1/4)⁻ˣ is applicable as (1/4)-1=4>1
(c) f (x)=(2/3)ˣ is not applicable because 2/3<1
d) f (x)= (2.3)ˣ is applicable as 2.3>1
e) f (x)=(.8)ˣ is not applicable, 0.8<1.
So options (a), (b) and (d) are applicable for exponential growth functions.

In ΔMNO, n = 92 inches, ∠N=119° and ∠O=20°. Find the length of m, to the nearest 10th of an inch.
Answer:
Step-by-step explanation:
The length of the side of the triangle will be 69 inches.
What is the sine law?The Law of Sines The law of trigonometric functions, sine law, sine formula, or sinusoidal rule is a trigonometric equation that relates the sizes of any triangle's edges to the sines of its orientations.
The sine law in the triangle ΔMNO is given as,
n / sin N = m / sin M = o / sin O
The third angle is calculated as,
∠M + ∠N + ∠O = 180°
∠M + 119° + 20° = 180°
∠M = 41°
The length m is calculated as,
n / sin N = m / sin M
92 / sin 119° = m / sin 41°
m = 69 inches
The length of the side of the triangle will be 69 inches.

There were 54 runners to start a race. In the first half of the race, 1/3 of them dropped out. In the second half of the race, 5/6 of the remaining runners dropped out. How many runners finished the race?
Answer:
6 runners finished the race
Step-by-step explanation:
Total number of runners = 54
In the first half of the race, 1/3 of them dropped out
= 1/3 of 54
= 1/3 * 54
= 54/3
= 18 runners
Runners remaining after first half = total runners - dropped out runners at first half
= 54 - 18
= 36 runners
In the second half of the race, 5/6 of the remaining runners dropped out
= 5/6 * 36
= (5*36)/6
= 180/6
= 30 runners
Runners remaining after second half = runners remaining after first half - dropped out runners at second half
=36 - 30
= 6 runners
Therefore, 6 runners finished the race

What is the solution set of 4x = y and [tex]2x^{2} -y=0[/tex]
A.
{(0.5, -0.5), (2, -8)}
B.
{(0, 0), (2, 8)}
C.
{(1.5, 2), (8, 2)}
D.
{(-1.5, -2), (2, 8)}
Answer:
B.
{(0, 0), (2, 8)}
Step-by-step explanation:
Substitute 4x in for y in the second equation.
[tex]2x^{2} - 4x = 0\\[/tex]
2x(x - 2) = 0
x = 0 or x - 2 = 0
x = 2
Substitute x = 0 and x = 2 in the first equation to get the corresponding values for y
4(0) = y and 4(2) = y
y = 0 or y = 8
So, B is the correct answer
