Step-by-step explanation:
The odds of grabbing a yellow marble from the bag are 7/30 or 0.233.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The odds of grabbing a yellow marble can be find by dividing the number of yellow marbles by the total number of marbles in the bag:
Odds of grabbing a yellow marble = Number of yellow marbles / Total number of marbles
By given there are 7 yellow marbles and a total of 30 marbles in the bag, so:
Odds of grabbing a yellow marble = 7 / 30.
Therefore, the odds of grabbing a yellow marble from the bag are 7/30 or approximately 0.233 or 23.3%.

PLEASE ANSWER FAST!!!
An object is launched vertically at a velocity of 160 feet per second from the top of a building 100 feet above the ground. Use the model h=-16t^2+vt+c where h is the height of the object at any time t, c is the initial height, in feet, of the object, t is the time in seconds and v is the velocity of the object.
How long will it take the object to reach the maximum height, and what is the maximum height?(Round to the nearest whole number)
Answer:
The question let's us set up the equation
Hope it helps!
Step-by-step explanation:
160= 16t^2+96t+16 and we just solve for t to get t= 3(sqrt 2 - 1) and -3(sqrt 2 - 1).

Find the distance CD rounded
to the nearest tenth.
C = (-5,4) D = (5,8)
CD = [?]
HINT: Use the distance formula:
d = V(x2 - xı)2 + (y2 - yı)2
Answer:
The distance is of 10.8 units.
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
In this question:
C(-5,4) and D(5,8). So
[tex]D = \sqrt{(5-(-5))^2 + (8-4)^2} = \sqrt{10^2 + 4^2} = 10.8[/tex]
The distance is of 10.8 units.

You construct a picture frame with a diagonal piece attached to the back for support, as shown below. Can you tell from the dimensions whether the corners of the frame are right angles?
222Answer:
Step-by-step explanation:
As a given dimension of the rectangle frame satisfied the Pythagoras theorem, so the frame consists of right angles.
What is a rectangle?The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.
Here,
Constructed a picture frame with a diagonal piece attached to the back for support, as shown.
To check from the dimensions whether the corners of the frame are right angles, so from observation, the figure is of a rectangle, It must satisfy the Pythagoras theorem.
Diagonal = 39
Diagonal = √[15² + 36²]
Diagonal = √1521
DIagonal = 39
Thus, as a given dimension of the rectangle frame satisfied the Pythagoras theorem, so the frame consists of right angles.

To purchase $13,900 worth of lab equipment for her business, Amy made a down payment of $1900 and took out a business
loan for the rest. After 3 years of paying monthly payments of $365.07, she finally paid off the loan.
Answer:
The total cost was $ 15,042.52, and the interest percentage applied on the loan was 8.22%.
Step-by-step explanation:
Given that to purchase $ 13,900 worth of lab equipment for her business, Amy made a down payment of $ 1900 and took out a business loan for the rest, and after 3 years of paying monthly payments of $ 365.07, she finally paid off the loan to determine the total cost and interest applied on the loan, the following calculation must be made:
(365.07 x 12 x 3) + 1900 = Total cost
4,380.84 x 3 + 1900 = Total cost
13,142.52 + 1900 = Total cost
15,042.52 = Total cost
13900 = 100
15042.52 = X
15042.52 x 100/13900 = X
1,504,252 / 13,900 = X
108.22 = X
Therefore, the total cost was $ 15,042.52, and the interest percentage applied on the loan was 8.22%.
I have 48 candys for 50cents each, how much total will I have after I sell all 48 candies?
Answer:
the answer is 2400 cents
Step-by-step explanation:
if you have 48 candies and each cost 50 cents so u meltiply 48 with 50. so if u mutiply them u get 2400cents, but if u want them in dollar then 1 dollar is 100 cent so if 1 dollar = 100 cent
? = 2400 cent
you criss -cross them so when u do 2400 multiplyed by 1 is 2400 and 100 multiplyed by ? is 100?
so your going to get this
2400 = 100?
so u divide both sides by 100 because u want "?" alone. so when u do 100 will vanish because you divided both sides with 100
so it will look something like this
2400/100 = ?
when u divide 2400 with 100 u get 24.
what does that mean? it mean 2400 cents are 24 dollars
do you get it?

Use the INCLUSIVE definition of a trapezoid to identify the TRUE statement. Select all that apply.
No parallelograms are trapezoids.
All parallelograms are trapezoids.
No trapezoids are parallelograms
Trapezoids do not have any parallel sides
A trapezoid has at least one pair of parallel sides.
(I’ll mark brainlist of you wrote down, not link’)
Answer:
All parallelograms are trapezoids.
No trapezoids are parallelograms.
A trapezoid has at least one pair of parallel sides
Step-by-step explanation:
1. Since a parallelogram has two pairs of parallel sides then it has at least one pair of parallel sides. Therefore, all parallelograms are also classified as trapezoids.
2. Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram.
3. A trapezoid has one pair of parallel sides.
(I can't put a picture, but I would if I could)
The statement "All parallelograms are trapezoids", statement "No trapezoids are parallelograms" and statement "A trapezoid has at least one pair of parallel sides" are correct.
What is a trapezoid?It is defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.
A parallelogram has at least one pair of parallel sides, since it has two pairs of parallel sides. As a result, all parallelograms are considered trapezoids.
Parallelograms have two pairs of parallel sides, whereas trapezoids have only one pair. A parallelogram can never be a trapezoid.
Thus, the statement "All parallelograms are trapezoids", statement "No trapezoids are parallelograms" and statement "A trapezoid has at least one pair of parallel sides" are correct.

Using the z-distribution, it is found that characteristics are:
a) 0.2
b) 0.0058
c) z = 2.575
d) 0.0149
e) (0.1851, 0.2149).
f) We are 99% confident the true proportion of adults who purchased something online is between 0.1851 and 0.2149.
Item a:
The point estimate is the sample proportion, hence:
[tex]\pi = \frac{789}{4750} = 0.2[/tex]
Item b:
The standard error is:
[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.2(0.8)}{4750}} = 0.0058[/tex]
Item c:
99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so [tex]z = 2.575[/tex].
Item d:
The margin of error is:
[tex]M = zs = 2.575(0.0058) = 0.0149[/tex]
Item e:
The interval is the point estimate plus/minus the margin of error, hence
[tex]\pi - M = 0.2 - 0.0149 = 0.1851[/tex]
[tex]\pi + M = 0.2 + 0.0149 = 0.2149[/tex]
The 99% confidence interval estimate of the population proportion of adults who had purchased something online is (0.1851, 0.2149).
Item f:
We are 99% confident the true proportion of adults who purchased something online is between 0.1851 and 0.2149.
