A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number can be repeated. You can choose from among four letters, A, B, C, and D, and two numbers, 5 and 6.
The size of the sample space is ___
If a code is chosen at random, the probability that it has a letter that immediately follows an odd number is ___
If a code is chosen at random, the probability that D is in the code but is not in the first position is ___
ANSWER ALL 3
The probability that it has a letter that immediately follows an odd number 1/2. The probability that D is in the code but is not in the first position 1/4.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

You can choose from among four letters, A, B, C, and D, and two numbers, 5 and 6.
The size of the sample space is (8, 16, 20, and 24)
If a code is chosen at random,
The probability that it has a letter that immediately follows an odd number (1/8, 1/6, 1/3, 2/5, 2/3)
= 1/2

What is the slope of the figure below? Write your answer as a rational number.
Answer:
2/3
Step-by-step explanation:
Slope = the rise over run! So if you calculate (or just count) the rise and run between point (-3,6) and (0,4), it is 2 over 3, which cannot be further simplified so it is just the fraction 2/3.

I really need help with this asap!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Radius=10
Diameter=20
circumference=62.8
Area=314
Answer:
Radius: 10 inches
Diameter: 20 inches
Circumference: 62.8 inches
Area: 314 inches squared
Step-by-step explanation:
Radius:
They have already given you the radius (10), so no formula is needed.
Diameter:
To find the diameter, multiply the radius by 2, so:
2 × 10 = 20
Circumference:
To find the circumference, use this formula:
C=2πr
2 × π (3.14) = 6.28
6.28 * 10 = 62.8
Area:
To find the area, use this formula:
A=πr²
π (3.14) × 100 = 314

Answer:
In bold answers with correct units
3) 6 x 3 = 18 + 1/2 x 12 x 15 = 90 = 90+ 18 = 108ft^2
4) = 12 x 12 = 144 + 4x4 = 16 +12 x 4 = 48 = 144+12+48 = 204m^2
5) = 8 x 12 = 96 + 1/2 x 4 x 6 = 12 = 108ft^2
6) = 3x 3 = 9 + pi3^2 = 28.2743339 (x2) =56.5486678 + 9 = 65.5m^2
proves 4 semi circles = 2 circles
7) 10 x 8 = 80 +4 x 4 = 16 + 1/2 x 2 x 4 = 4 = 20+80= 100ft^2
proves 14-8-4 = 2ft is the triangle length and 10-6 = 4 the triangle height.
8) 4x6 = 24 + 1/2 x 4 x 2 = 4 + pi 4^2 = 1/2 x 50.2654825 = 24+4 + 25.1329 = 53.1m^2
Will give brainliest!! Using the measurements of the shapes.. determine the perimeter of the irregular polygon.
.
Answer:
[tex]p=30.7\:\text{units},\\A=40.2\:\text{square units}}[/tex]
Step-by-step explanation:
The irregular shape's area consists of the sum of the areas of all the shapes that make it up.
Area of pink triangle: [tex]\frac{1}{2}\cdot 3 \cdot 3=4.5[/tex]
Area of purple square: [tex]3^2=9[/tex]
Area of green quadrilateral: [tex]3\cdot 2.9=8.7[/tex]
Area of blue triangle: [tex]\sqrt{10.25(10.25-8.5)(10.25-6)(10.25-6)}=17.99989[/tex]
Therefore, the area of the irregular polygon is [tex]4.5+9+8.7+17.99989\approx \boxed{40.2\:\text{square units}}[/tex].
The perimeter of the irregular polygon consists of certain shred sides from the four polygons that make up:
[tex]p=3+3+3+3+6+8.5+4.2=\boxed{30.7\:\text{units}}[/tex]
Are these correct. If they're not tell me which and how to solve, please?

How to find the all 4 angles of a trapezoid given only the side lengths
Answer:
Angle Measures on the same side between the bases are supplementary
Supplementary means they add up to 180 degrees
Step-by-step explanation:
Equation : m∠1 + m∠2 = 180°
110° + m∠2 = 180°
-110° -110°
m∠2 = 70°
