Step-by-step explanation:
The sample space for rolling two dice consists of 36 possible outcomes, as each of the six faces on the first die can be combined with any of the six faces on the second die.
To find the probability of showing either a prime number on the first die or a multiple of 5 on the second die, we can use the principle of inclusion-exclusion.
There are 3 prime numbers on a standard die: 2, 3, and 5. And there are two multiples of 5: 5 and 10. However, we need to be careful not to count the outcome (5,5) twice, as it satisfies both conditions.
So, the probability of showing either a prime number on the first die or a multiple of 5 on the second die is:
P(prime or multiple of 5) = P(prime) + P(multiple of 5) - P(prime and multiple of 5)
P(prime) = 3/6 = 1/2
P(multiple of 5) = 2/6 = 1/3
P(prime and multiple of 5) = 1/36
Therefore,
P(prime or multiple of 5) = 1/2 + 1/3 - 1/36
= 19/36
So the probability of showing either a prime number on the first die or a multiple of 5 on the second die is 19/36, or approximately 0.528.

Area of the base is 9 square feet, the lateral face area is 27 square feet, Lateral surface area is 27 square feet and total surface area is 36 square feet.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The square has a side length of 3 ft
Area of the base is 3×3
Area of the base is 9 square feet
Now let us find the lateral face area = 2a√[(a²/4) + h²]
=2(3)√[(9/4) + 17.64]
=6√20
=27 square feet
Lateral surface area = a√(a²+4h²)
a=3, h=4.2
Lateral surface area = 3√(9+4(4.2)²)
= 3√(9+4(17.64))
3√(9+70.56
= 3√79.56
=3×9
=27 square feet
To find total surface area, we have to find the slant height by pythagoras theorem
(1.5)²+(4.2)²=l²
2.25+17.64=l²
20=l²
4.47=l
Now total surface area = a² + 2al
=3²+2(3)(4.47)
=9+26.82
=36 square feet
Hence, Area of the base is 9 square feet, the lateral face area is 27 square feet, Lateral surface area is 27 square feet and total surface area is 36 square feet.

Step-by-step explanation:
I know this answer is right because the numbers got larger as the letters went to the right which means increase and the answers and graph makes logical sense to me. Hopefully you get a good grade on this.
Answer:
The correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16
step by step:
From the number line we can observed that:
1) A, B, C and D lies between -1 and 0.
2) Point A and B lies between -1 and -0.5
3) Point C and D lies between -0.5 and 0
Therefore, the value of A and B must have a negative value lying between -1 and -0.5
Also, the value of C and D must have a negative value lying between -0.5 and 0.
Now consider the provided options.
Option A) A=-5/16,B=-9/16,C=-0.7,D=-0.4
This is Incorrect representation because the value of C and D should lying between -0.5 and 0.
Option B) A=-0.4,B=-0.7,C=-5/16,D=9/16
This is Incorrect representation because the value of A and B should lying between -1 and -0.5.
Option C) A=9/16,B=-5/16,C=-0.4,D=-0.7
This is Incorrect representation because the value of C and D should lying between -0.5 and 0.
Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16
Here the value of A and B lying between -1 and -0.5 also the value of C and D lying between -0.5 and 0.
Also they are in ascending order from -1 to 0.
Hence, the correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

Therefore, I got 4288 units :)
How would you solve this without S.A formulas
Answer:
Step-by-step explanation:
Length of the object = 4 ft
Breadth of the object = 4 ft
Height of the object = 3 ft
Volume / Area of the object = Length * Breadth * Height
= 4 * 4 * 3
= 48 ft³
Length of the cubical hole = 2 ft
Breadth of the cubical hole = 2 ft
Height of the cubical hole = 3 ft
Volume / Area of the cubical hole = Length * Breadth * Height
= 2 * 2 * 3
= 12 ft³
Remaining Area of the object = Area of the object - Area of the cubical hole
= 48 - 12 ft
= 36 ft
We can’t tell any area of a 3d object without it’s SA formulas.

Students were surveyed to determine their favorite types of animals. The bar graph shows the number of students who selected each type of animal. 80% 5% 6% Type of Animal 20% Fish Lizard Bird 6 8 Number of Students What percentage of the students surveyed selected "Bird" as their favorite type of animal? Dog Cat 10 2 Favorite Animals 10
20% of the students surveyed selected "Bird" as their favorite type of animal. Hence option D is correct.
What is the percentage of Bird?To calculate the percentage of students who selected "Bird" as their favorite type of animal, we need to first determine the total number of students surveyed. From the bar graph, we can see that the total number of students is:
2 + 4 + 6 + 10 + 8 = 30
The number of students who selected "Bird" as their favorite type of animal is 6. To calculate the percentage, we can use the following formula:
Percentage = (Number of students who selected "Bird" / Total number of students surveyed) x 100%
Substituting the values we have:
Percentage = (6 / 30) x 100%
Percentage = 20%
Therefore, 20% of the students surveyed selected "Bird" as their favorite type of animal.

Complete the chart in model it on the previous page. Describe and explain the relationship between the decimals for 2/6 and 4/6
Answer: The relationship between the decimals for 2/6 and 4/6 is that the decimal for 4/6 is twice the decimal for 2/6.
When we simplify 2/6, we get 1/3, which is equivalent to 0.33 as a decimal. When we simplify 4/6, we get 2/3, which is twice the value of 1/3. So the decimal for 4/6 is twice the decimal for 2/6, which means that they have a proportional relationship.
