Step-by-step explanation:
i got it wrong and it showed this instead
a-0.23125
b-720
The required,
(a) The experimental probability that a randomly selected worker at that company walks to work is approximately 0.23125 or 23.125%.
(b) we can predict that about 762 of the 3300 workers at the company walk to work.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
a. The experimental probability of a randomly selected worker at that company walking to work can be calculated as the ratio of the number of workers who walk to work to the total number of workers surveyed:
Experimental probability = Number of workers who walk to work / Total number of workers surveyed
Experimental probability = 37 / 160
Experimental probability = 0.23125 or 23.125%
Therefore, the experimental probability that a randomly selected worker at that company walks to work is approximately 0.23125 or 23.125%.
b. To predict about how many of the 3300 workers at the company walk to work, we can use the experimental probability calculated above to estimate the number of workers who walk to work out of the total number of workers:
Number of workers who walk to work = Experimental probability x Total number of workers
Number of workers who walk to work = 0.23125 x 3300
Number of workers who walk to work = 762.375
Therefore, we can predict that about 762 of the 3300 workers at the company walk to work.

REPOST, SOMEONE PLEASE HELP I DONT WANT TO KEEP WASTING ALL MY POINTS ON 1 QUESTION!!!!!!!
Answer:
:
1.
centre(h,k)=(-13,9)
radius (r)=6
we have
equation of the circle is
(x-h)²+(y-k)²=r²
(x+13)²+(y-9)²=6²
(x+13)²+(y-9)²=36you can write this equation too
x²+26x+169+y²-18y+81=36
x²+y²+26x-18y+169+81-36=0
x²+y²+26x-18y +214=0
is a required equation of the circle.
2.
centre(h,k)=(1,-1)
radius (r)=11
we have
equation of the circle is
(x-h)²+(y-k)²=r²
(x-1)²+(y+1)²=11²
(x-1)²+(y+1)²=121
you can write this equation too
x²-2x+1+y²+2y+1=121
x²+y²-2x+2y=121-2
x²+y²-2x+2y=119
is a required equation of the circle.
3.
centre (h,k)=(3,1)
radius (r)=4units.
we have
equation of the circle is
(x-h)²+(y-k)²=r²
(x-3)²+(y-1)²=4²
(x-3)²+(y-1)²=16 is a required equation.
4.
centre(h,k)=(4,-2)
radius (r)=3
we have
equation of the circle is
(x-h)²+(y-k)²=r²
(x-4)²+(y+2)²=3²
(x-4)²+(y+2)²=9
you can write this equation

Find the volume and round to the nearest tenth
Answer:
6 x 4 = 24
24 x 15.3 = 367.2
half of 4 is = 2
2^2 = 4
4 x 3.14 = 12.56
12.56 divided by 2 = 6.28
6.28 x 15.3 = 96.084

Jessica is eating a bag of Sour Skittles. Her friend asks her to share, and Jessica throws over an extra bag. Her friend does not catch the bag, and it hits the ground. The distance from the ground (height) for the bag of candies is modeled by the function h(t)=−16t2+32t+4h(t)=−16t
2
+32t+4, where h(t) is the height (distance from the ground in feet) of the candies and t is the number of seconds the candies are in the air. Describe in a paragraph what the graph of this scenario would look like.
Answer:
A parabola opens downward with vertex at (1,20)
The function that models the height of bag of candies is
The graph of this function is a parabola that opens downward.
To find the maximum height of the candy bag, we complete the squares to obtain the vertex form of the function.
Factor -16 to get;
Add and subtract the square of half the coefficient of t.
Factor the perfect square trinomial:
The vertex is (1,20)
This means the maximum height after 1 second is 20 feet.

endpoint
right angle
obtuse angle
Answer:
top box: ray
bottom box: endpoint
Step-by-step explanation:
top box: a ray is a line that doesn't stop and that is represented by a arrow on the end of it
bottom box: an end point is where a ray, or line segment stop and since i see two rays that stop there it is an endpoint

Answer:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate.
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Find the area of each figure
Answer:
1824in. 2
Step-by-step explanation:
first, we need to cut it to two figure (a triangle and a rectangle), then calculate each of the area.
the area of triangle
= 12in.×48in.×1/2
= 576in.2×1/2
= 288in.2
the area of rectangle
= 32in.×48in.
= 1536in.2
the area
= 288in.2+1536in.2
= 1824in.2

What is the measure of angle BGC??
The perimeter of a square is (8x + 6) centimeters. Part A: Write an expression for the length of a side of the square. Part B: The perimeter of the square is 72 centimeters. Write and solve an equation to find the value of x, then find the side length of the square.
Step-by-step explanation:
Part A:
(8x+6)/4= 2x+ 1.5
Part B:
72= (8x+6)
8x= 72-6
8x= 66
x= 8.25
the side length = 2x+1.5= 2(8.25)+1.5= 18 centimetres

Area of a Circle: A = πr²
r is radiusStep-by-step explanation:
*Note: A semicircle is half a full circle.
Step 1: Define
Radius r = 10 cm
Step 2: Solve for A
Rewrite Area of Circle Formula: A = 0.5πr²Substitute in r [Area of Semicircle Formula]: A = 0.5π(10 cm)²[Area] Evaluate exponents: A = 0.5π(100 cm²)[Area] Multiply: A = 50π cm²You can paint 8 square feet in 2 hours. How many square feet can you paint in 7 hours
8 square feet = 2 hours
°divide 2hrs to 8 square feet
1hr = ?
2÷8 =4
so,
1hr = 4 square feet
●In 1 hour 4 square feets will be covered•4 square feet can be painted in 1 hour.
*now to find how many square can be painted in 7 hrs.
°multiply no. of hours to hd no. of square feet per hour.
7hrs = ?
7×4 =28
So,
●28 square feet would be covered in 7 hours.may this helps you
