The probability that he catches 2 red balls and 1 ball of each of the other colors is 150/792.
Given that, total number of balls=12, red number of balls =3, green number of balls=3, blue number of balls =3 and white number of balls =3.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
Here, C(n,r)= n!/r!(n-r)!
Now, C(12, 5)= 12!/5!(12-5)!
= 12!/5!(7)!
= (12×11×10×9×8×7!)/(5×4×3×2×1)×7!
= 3×11×2×3×4
= 792
Now, C(5, 2)= 5!/2!(5-2)!
= 5!/2!(3)!
= 10
Now, C(5, 1)= 5!/1!(5-1)!
= 5
So, he catches 2 red balls and 1 ball of each of the other colors
= 10×5×3
= 150
The probability of an event = 150/792
Therefore, the probability that he catches 2 red balls and 1 ball of each of the other colors is 150/792.

• A baker uses 3 tablespoon of melted butter for every kilogram of flour.
How many tablespoons of melted butter he used for 13 kilograms of
flour?

חח ך
Answer:
48.6 tablespoons
Step-by-step explanation:
If for every kg of flour 3.6 (3 3/5) tablespoons are used, then for 13.5 (13 1/2) kgs: 3.6 × 13.5 = 48.6 tablespoons are used.
From the question,
[tex]3\frac{3}{5}[/tex] tablespoons of melted butter = 1 kilogram of flour
The number of tablespoons of melted butter the baker can use for 13 kilograms of flour is calculated as
1 kilogram of flour = [tex]3\frac{3}{5}[/tex] tablespoons of melted butter
[tex]13\frac{1}{2}[/tex] kilograms of flour = b
Cross multiply
1 kilogram of flour x b = [tex]13\frac{1}{2}[/tex] kilograms of flour x [tex]3\frac{3}{5}[/tex] tablespoons of melted butter
b = [tex]13\frac{1}{2}[/tex] kilograms of flour x [tex]3\frac{3}{5}[/tex] tablespoons of melted butter /1 kilogram of flour
b = 48.6 tablespoons of melted butter
Therefore, the baker would use 48.6 tablespoons of melted butter for [tex]13\frac{1}{2}[/tex]kilograms of flour.

Jane ran 8 fewer miles this week than last week. This week, she ran 10 times
as far as John. John ran 3 miles. How many miles did Jane run last week?
Step-by-step explanation:
John ran 3 miles this week.
Jane ran 10 times as far as John this week :
10×3 = 30 miles
but she ran this week 8 fewer miles than last week. in other words, last week she ran 8 miles more than this week :
30 + 8 = 38 miles.
so, last week she ran 38 miles.

Answer:
first term = 3
Step-by-step explanation:
The n th term of a GP is
[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here r = 3 and a₅ = 243 , thus

a₁ × 81 = 243 ( divide both sides by 81 )
a₁ = 3

The difference of two supplemtary angles is 58 degrees. Find the measures of the angles
Answer:
The measure of the angles are 61° and 119°
Step-by-step explanation:
Let the first angle = x°
let the second angle = y°
The sum of two supplementary angles = 180°
x° + y° = 180° ----- equation (1)
based on the given question; "the difference of two supplementary angles is 58 degrees."
x° - y° = 58° ------- equation (2)
from equation (2), x° = 58° + y°
Substitute the value of x into equation (1)
(58° + y°) + y° = 180°
58 + 2y = 180
2y = 180 -58
2y = 122
y = 122 / 2
y = 61°
The second angle is given by;
x° = 58° + y°
x = 58° + 61°
x = 119°
Thus, the measure of the angles are 61° and 119°

Triangle XYZ is rotated to create the image triangle X'Y'Z'.
On a coordinate plane, 2 triangles are shown. The first triangle has points X (negative 2, 2), Y (1, 2), Z (0, 4). The second triangle has points X prime (2, negative 2), Y prime (negative 1, negative 1), Z prime (0, negative 4).
Which rules could describe the rotation? Select two options.
R0, 90°
R0, 180°
R0, 270°
(x, y) → (–y, x)
(x, y) → (–x, –y)
Answer:
R0, 180°
(x, y) → (–x, –y)
Step-by-step explanation:
Knowing that:
The coordinates of ΔXYZ is x '(-2, 2), Y(1, 2), Z(0, 4)
The coordinates of ΔX'Y'Z' is x'(2, -2), Y'(-1, -1), Z'(0, -4)
Coordinates of the preimage = (x, y)
Coordinates of the image = (-x, -y)
transformation by rotation 180° about the origin.
