Answer:
a) The theoretical probability of drawing a blue marble is the ratio of the number of blue marbles to the total number of marbles in the bag, which is:
P(blue) = number of blue marbles / total number of marbles
= 290 / 630
= 29 / 63
So the theoretical probability of drawing a blue marble is 29/63.
b) The experimental probability of drawing a blue marble is the ratio of the number of times a blue marble was actually drawn to the total number of trials, which is:
P(experimental blue) = number of times a blue marble was drawn / total number of trials
= 44 / 100
= 11 / 25
So the experimental probability of drawing a blue marble is 11/25.

One solution of a quadratic equation is 8. What do you know about the quadratic equation? What are two ways you would know if a quadratic equation could have this solution?
(picture)
Answer:
factor it and see if one of those factors is x − 8 x-8 x−8 ...
Step-by-step explanation:
Therefore, if the quadratic equation has a solution of 8, then it must have a factor of. Since x − 8 x-8 x−8 must be a factor of any quadratic equation that has a solution of 8, the first way you could determine if a quadratic equation has a solution of 8 is to
Angelica’s speed is 4 cm/minute, Monique’s speed is 3. 5 cm/minute, and Courtney’s speed is 5. 5 cm/minute. Which turtle will win the race? Explain your reasoning.
Answer:
C O U R T N E Y
Step-by-step explanation:
Look at their speed… meaning;
Angelica can run 4 cm per minute
Monique can run 3.5 cm per minute
And Courtney can run 5.5 cm per minute
The longest one is the fastest one
It says “per minute (/minute) which means courtney will win he can run to 5.5 cm in just a minute, but the others is slower than her

Original number of students: 56
New number of students: 77
Find the percent of change. Round your answer to the nearest tenth of a percent, if necessary.
Answer:Therefore, the percent change from 56 to 77 students is 37.5%.
Step-by-step explanation:
students, we can use the following formula:
percent change = ((new number - old number) / old number) x 100%
Plugging in the values given in the problem, we get:
percent change = ((77 - 56) / 56) x 100%
percent change = (21 / 56) x 100%
percent change = 0.375 x 100%
percent change = 37.5%
Therefore, the percent change from 56 to 77 students is 37.5%.
Answer: 37.5%

Step-by-step explanation:
13oz bottle of dish soap sells for 2.34
Answer: hope this helps ♡
The unit price of the 13 oz bottle is $0.18 per oz
The unit price of the 30 oz bottle is $0.53 per oz
The 13 oz bottle for $2.34 is a better deal.
Step-by-step explanation:
Unitary method: diving the number that you want to find out over the already known number. (just try to understand this lol) :)
13 oz = $2.34
13 oz bottle is $? per oz
[tex]\frac{2.34}{13}[/tex] = 0.18
1 oz = $0.18
(double check: 0.18×13=2.34)
30 oz = $15.90
30 oz bottle is $? per oz
[tex]\frac{15.9}{30}[/tex] = 0.53
1 oz = $0.53
(double check: 0.53×30=15.9)
The 13 oz bottle for $2.34 is a better deal.

A pattern of triangular numbers is shown. The first is 1, the second is 3, the third is 6, and so on. The formula 0.5n2 + 0.5n can be used to find the nth triangular number. Is 50 a triangular number? Explain.
(picture)
Answer:
50 is not a triangular number
Step-by-step explanation:
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 =55
The way to calculate triangle numbers is to add the corresponding number.
For example, 1 is a triangle 1 + 2 is a triangle 1 + 2 + 3 is a triangle so on and so forth.
Triangle numbers would be 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, and 91

Which expression represents the sum of 2/3m - 1 1/6 and 5/6m - 1 1/3?
HOW DO I DO THIS??????
Answer:
-m+15/6
2/3m-5/3m-5/2
Answer: 1 5/6m - 2 1/2
Step-by-step explanation:
(2/3m - 1 1/6) + (5/6m - 1 1/3)
2/3m X 2 = 4/6m
4/6m + 5/6m = 11/6m=1 5/6m

The necklace charm shown has two parts, each shaped like a trapezoid with identical dimensions.
What is the total area, in square millimeters, of the charm?
Enter your answer in the box.
Answer:
855mm
Step-by-step explanation:
A = (b₁ + b₂)h / 2
A = (25mm + 32mm)(15 mm) / 2
A = 427.5 mm²
total area = (427.5 mm²)(2)
total area = 855 mm²
Answer:855mm

A sculpture is made of solid nickel in the shape of a cone. The sculpture is 84 inches tall, and its base has a diameter of 16 inches. If nickel costs $2.25 per cubic inch, how much did the nickel for the sculpture cost?
Use 3.14 for pi, and do not round your answer.
The total cost of the nickel for the sculpture is $12,660.48.
We know that the volume of a cone is:
v = 1/3πr²h ......(i)
where r ⇒ radius of the cone
h ⇒ height of the cone
Now, as per the question,
r = diameter/2 = 16÷2 = 8 inches
h = 84 inches
Putting the values in equation (i)
v = 1/3 × 3.14 × (8)² × 84
v = 5626.88 cubic inch
The cost given for nickel = $2.25 per cubic inch
So, the total cost for the nickel used in making the sculpture:
the volume of cone × cost per cubic inch
5626.88 × 2.25 = $12,660.48
Therefore, the total cost for the nickel used is $12,660.48
