Given that event A is known to occur and both events A and B have nonzero probabilities, we can conclude that the probability of event B occurring is zero. So, the correct answer to your question is: d. zero

If events A and B are mutually exclusive, it means that they cannot occur at the same time. So, if we know that event A has occurred, we can safely say that event B cannot occur. Therefore, the probability of the occurrence of event B given that event A has occurred is zero. Therefore, the correct answer is d) zero.

Mutually exclusive events are a fundamental concept in probability theory. It means that the occurrence of one event excludes the occurrence of another event. For example, when flipping a coin, the event of getting heads is mutually exclusive with the event of getting tails. It is impossible to get both heads and tails at the same time.

Understanding mutually exclusive events is important because it helps us to calculate the probability of combined events. For mutually exclusive events, we can simply add their probabilities to get the probability of their union. However, if events are not mutually exclusive, we need to subtract the probability of their intersection to avoid counting the same outcome twice.

Answer:

x ≈ 36.2

Step-by-step explanation:

the segment from the vertex of the triangle to the base is a perpendicular bisector, then

consider the right triangle on the right with legs 15 and 33 , hypotenuse x

using Pythagoras' identity in the right triangle

x² = 15² + 33² = 225 + 1089 = 1314 ( take square root of both sides )

x = [tex]\sqrt{1314}[/tex] ≈ 36.2 ( to the nearest tenth )

Answer:

36.2

Step-by-step explanation:

The tick marks on the two sides of the triangle indicate that the sides are of equal length. Therefore, as the triangle has two sides of equal length, it is an isosceles triangle.

In an isosceles triangle, the altitude is the perpendicular bisector of the base. Therefore, the triangle is made up of two congruent right triangles with:

To calculate the value of x, we can use Pythagoras Theorem:

[tex]\boxed{a^2+b^2=c^2}[/tex]

where:

Substitute the values into the formula and solve for x:

[tex]\implies 15^2+33^2=x^2[/tex]

[tex]\implies 225+1089=x^2[/tex]

[tex]\implies 1314=x^2[/tex]

[tex]\implies x^2=1314[/tex]

[tex]\implies \sqrt{x^2}=\sqrt{1314}[/tex]

[tex]\implies x=36.2491379...[/tex]

[tex]\implies x=36.2\; \rm (nearest\;tenth)[/tex]

Therefore, the value of x is 36.2 units (nearest tenth).

Answer: answer is 3

Step-by-step explanation:

The value of the equation in terms of x is x = [tex]\sqrt{\frac{y^2-270}{135}}[/tex].

Given is an equation, y = 3√(x²+2)15, we need to convert it in terms of x,

So,

y = 3√(x²+2) 15​

Squaring both sides,

y² = 9 [(x²+2)15]

y² = 9 [15x²+30]

y² = 135x²+270

y²-270 = 135x²

y²-270 / 135 = x²

x = [tex]\sqrt{\frac{y^2-270}{135}}[/tex]

Hence, the value of the equation in terms of x is x = [tex]\sqrt{\frac{y^2-270}{135}}[/tex].

The cook made 9 servings of baked beans.

We have,

To find the number of servings of beans, we need to divide the total amount of baked beans by the number of baked beans per serving.

Total amount of baked beans = 7 1/2 pints

Amount of baked beans per serving = 5/6 pint

Number of servings of beans = (7 1/2) ÷ (5/6)

Converting 7 1/2 to an improper fraction:

7 1/2 = (2 × 7) + 1 = 15/2

Number of servings of beans = (15/2) ÷ (5/6)

To divide fractions, we can multiply by the reciprocal of the divisor:

Number of servings of beans = (15/2) × (6/5)

Number of servings of beans = 45/5

Number of servings of beans = 9

The unit vector along the direction from Q to P is:

(-6 - m)/√(m² + 10m + 45) i + m/√(m² + 10m + 45) j - 3/√(m² + 10m + 45) k

What is unit vector?

A unit vector is a vector that has a magnitude of 1 and is usually used to indicate a direction in a vector space.

To find the unit vector along the direction of a vector from point Q to P, we first need to find the vector from Q to P.

The vector from Q to P is given by:

P - Q = [-1 - (5 + m)]i + [4 + m - 4]j + [-3 - (0 + m)]k

= [-6 - m]i + m j - 3k

To find the unit vector along this direction, we need to divide this vector by its magnitude:

|P - Q| = √[(-6 - m)² + m² + (-3)²] = √(m² + 10m + 45)

So, the unit vector along the direction from Q to P is:

(-6 - m)/√(m² + 10m + 45) i + m/√(m² + 10m + 45) j - 3/√(m² + 10m + 45) k

True. A counter variable is often used in loops to track the number of times the loop has executed.

In programming, a counter variable is a variable that is used to keep track of the number of times a loop has executed. A counter variable is usually initialized to a starting value, and then incremented or decremented with each iteration of the loop. The loop continues to execute as long as the counter variable meets certain conditions.

The purpose of a counter variable is to allow a loop to repeat a specific number of times. For example, if you want to repeat a block of code 10 times, you can set a counter variable to 0, and then use a loop to execute the code until the counter variable reaches 10.

Counter variables are commonly used in programming languages that support loops, such as C++, Java, Python, and JavaScript. They provide a simple and effective way to repeat code without having to write the same statements over and over again.

The probability of Shenanigans selling a Peanut Butter Cup cone next is approximately 31.22%.

To calculate the probability of Shenanigans selling a Peanut Butter Cup cone next, we need to determine the number of cones sold that were not Peanut Butter Cup cones and divide that by the total number of cones sold.

Given that Shenanigans sold a total of 711 ice cream cones last week and 489 of those were either Coffee Cream or Oreo, we can subtract 489 from 711 to find the number of cones that were not Coffee Cream or Oreo;

Number of cones that were not Coffee Cream or Oreo = 711 - 489 = 222

So, out of the total 711 cones sold, 222 were not Coffee Cream or Oreo cones. Therefore, the remaining cones must be Peanut Butter Cup cones.

Now, we can calculate the probability of selling a Peanut Butter Cup cone next by dividing the number of Peanut Butter Cup cones by the total number of cones sold, and then multiplying by 100 to find the result as a percentage;

Probability of selling a Peanut Butter Cup cone next = (Number of Peanut Butter Cup cones / Total number of cones sold) × 100

1805/3=601.7^3

Frido has V=4873.5

601.7x8.1=4873.5

8.1 as a percent is 8.1x100=810%

So the answers are

A.

Ricardo’s pyramid has a volume of 601.7 in^3.

C.

Frido’s pyramid is 8.1 times larger than Ricardo’s.

F.

Frido’s pyramid is 810% larger than Ricardo’s.

The only correct statements are:

Ricardo’s pyramid has a volume of 601.7 in³.

Frido’s pyramid is 8.1 times larger than Ricardo’s.

Options A and C are the correct answer.

We have,

The volumes of square pyramids.

V = (1/3) x s² x h

For Ricardo's pyramid,

s = 19 inches

h = 5 inches.

Substituting these values into the formula, we get:

V = (1/3) x 19² x 5

V ≈ 601.7 in³

Therefore, statement A is correct.

We do not have enough information to determine the volume of Frido's pyramid directly using the given formula.

However, we can use the fact that the volume of a pyramid is proportional to the cube of its linear dimensions (i.e., the length of its sides).

So if Frido's pyramid has a volume that is k times larger than Ricardo's, then the ratio of their corresponding linear dimensions (i.e., side lengths) will be:

(k)^(1/3)

Using this information, we can compare the volumes of the two pyramids:

Frido's pyramid / Ricardo's pyramid = k

(Frido's pyramid / Ricardo's pyramid)^(1/3) = (k)^(1/3)

We are given that Frido's pyramid has a volume of 4873.5 in³.

so,

k = Frido's pyramid / Ricardo's pyramid

k = 4873.5 / 601.7

k = 8.1

Therefore, statement C is correct.

We can also use this value of k to compare the sizes of the two pyramids in other ways:

Frido's pyramid is 7.1 times larger than Ricardo's (k - 1 = 8.1 - 1 = 7.1).

so statement D is incorrect.

Frido's pyramid is approximately 80.5% larger than Ricardo's.

[(k - 1) x 100%

= (8.1 - 1) x 100%

= 750%,

so statement E is incorrect.

Frido's pyramid is approximately 710% larger than Ricardo's

= k x 100%

= 810%

so statement F is incorrect.

Therefore,

The only correct statements are:

Ricardo’s pyramid has a volume of 601.7 in³.

Frido’s pyramid is 8.1 times larger than Ricardo’s.
