The answer is 3. Choosing from 3 red marbles, 4 yellow marbles, and 8 blue marbles. The model provides an accurate representation of the items in the bag as each item is equally likely to be chosen.
What is a number cube?It is used in a variety of activities such as rolling dice games, probability experiments, and math activities.
The model of flipping a coin fifteen times is incorrect as it does not accurately represent the scenario. There is no representation of the different sports items in the bag.
The model of spinning a spinner with three equal sections is incorrect as the items in the bag are not equal and there are three sections in the spinner.
The model of rolling a number cube labeled one through six fifteen times is incorrect as the number cube does not accurately represent the sports items in the bag.
In conclusion, the best model to simulate the scenario with a sports bag containing 3 tennis balls, 4 baseballs, and 8 golf balls is 3. Choosing from 3 red marbles, 4 yellow marbles, and 8 blue marbles.

Answer:
56. Someone correct me if I'm wrong.
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean Theorem, which is a² + b² = c²
a and b are the legs, and c is the hypotenuse. Here, we know the length of one leg and the hypotenuse. So...
a² + 42² = 70²
First, we need to square these numbers. 42² is 1764. 70² is 4900. So...
a² + 1764 = 4900
Now, we can subtract 1764 from both sides.
a² + 1764 - 1764 = 4900 - 1764
That would give us...
a² = 3136
Now, we square root 3136.
So...
[tex]\sqrt{3136}[/tex] = 56
The missing side should be 56.

Step-by-step explanation:
In January, a puppy weighed 4kg.
Three months later, the same puppy weighed 5kg.
What was the percentage increase in the puppy's weight?
Answer:
25%
Step-by-step explanation:
5kg=5000g(a)
4kg=4000g(b)
p=percent
a=b+bxp/100
5000=4000+4000xp/100
5000-4000=40xp
1000=40xp
p=1000/40
p=25
R:25%
The percentage increase in the puppy's weight is 25% and this can be determined by using the unitary method.
Given :
In January, a puppy weighed 4kg. Three months later, the same puppy weighed 5kg.The following steps can be used to determine the percentage increase in the puppy's weight:
Step 1 - The unitary method can be used to determine the percentage increase in the puppy's weight.
Step 2 - According to the given data, in January, a puppy weighed 4kg. Puppy's weight is 4kg in January which is 100%.
Step 3 - So, if 4 kg is 100% then 5kg is equal to:
[tex]=\dfrac{100}{4}\times 5[/tex]
Multiply 100 by 5 in the above expression.
[tex]=\dfrac{500}{4}[/tex]
Divide 500 by 4 in the above expression.
= 125%
Step 4 - So, the percentage increase in the puppy's weight is:
= 125 - 100
= 25%

If

when

find,
y
when
x
=
225
Answer:
y = 75
Step-by-step explanation:
Given that:
y [tex]\alpha[/tex] [tex]\sqrt{x}[/tex]
⇒ y = k[tex]\sqrt{x}[/tex]
where k is the constant of proportionality.
When y = 45, x = 81, then;
45 = k[tex]\sqrt{81}[/tex]
45 = 9 k
k = [tex]\frac{45}{9}[/tex]
= 5
k = 5
So that,
y = 5[tex]\sqrt{x}[/tex]
the value of y when x = 225 is;
y = 5[tex]\sqrt{x}[/tex]
= 5 x [tex]\sqrt{225}[/tex]
= 5 x 15
y = 75

Answer:
Step-by-step explanation:
The sin(30) = 1/2
The sin(30) = 1/2 = opposite / hypotenuse
Opposite = 7
hypotenuse = opposite / sin(30)
hypotenuse = 7 / (1/2) = 7 *2 / 1 = 14
The long side can be found using the Pythagorian Theorem.
a^2 + b^2 = c^2
a = 7
b = ?
c = 14
14^2 = 7^2 + b^2
196 - 49 = b^2
147 = c^2
147 = 3*7 *7
sqrt(b^2) = sqrt(3*7*7)
b = 7 sqrt(3)

Find the value of x.
please help
Answer:
123 degrees
Step-by-step explanation:
Well, since we have a 4 sided figure, we know that the sum of the interior angles is 360 degrees.
(n-2)*180=(4-2)8180=360
Okay we are given 3 angles
120+43+74= 237
that means that x= 360-237
x=123 degrees
