(i) The probability of both events A and B happening, P(A and B), is 0.12. (ii) The probability of either event A or event B happening, P (A or B), is 0.58.

First, let's define what it means for events to be independent. Two events A and B are independent if the occurrence of one event does not affect the probability of the occurrence of the other event. In other words, the probability of both events occurring together is equal to the product of their individual probabilities: P (A and B) = P(A) x P(B).

Using this formula, we can find the probability of both events occurring together:
P (A and B) = P (A) x P(B) = 0.3 x 0.4 = 0.12

Now let's find the probability of either event occurring. We can use the formula P (A or B) = P (A) + P(B) - P(A and B).
We already know that P(A) = 0.3 and P(B) = 0.4, and we just found that P (A and B) = 0.12. Plugging those values into the formula, we get:
P (A or B) = 0.3 + 0.4 - 0.12 = 0.58
So, the probability of either event occurring is 0.58.
In summary:
(i) P (A and B) = 0.12
(ii) P (A or B) = 0.58

The interval that corresponds to the smallest area under a Normal curve is option D, μ - σ to Q3. This is because it covers only one standard deviation below the mean (μ - σ) and a smaller portion of the upper tail (up to Q3) compared to the other options. Smaller intervals generally correspond to smaller areas under the curve.

The interval that corresponds to the smallest area under a Normal curve is option D, μ - σ to Q3. This is because it covers only one standard deviation below the mean (μ - σ) and a smaller portion of the upper tail (up to Q3) compared to the other options. Smaller intervals generally correspond to smaller areas under the curve. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. Their importance is partly due to the central limit theorem. It states that, under some conditions, the average of many samples (observations) of a random variable with finite mean and variance is itself a random variable whose distribution converges to a normal distribution as the number of samples increases. Therefore, physical quantities that are expected to be the sum of many independent processes, such as measurement errors, often have distributions that are nearly normal.

This is a false statement because y-coordinates are different.

In mathematics, an ordered pair is a pair of elements, usually written in the form (x,y), where x and y are two values that are related in some way. In the case of (8,8), this represents an ordered pair where the value of x is 8 and the value of y is 8.

On the other hand, (9-1, 6+3) can be simplified using basic arithmetic operations. We first evaluate the expressions inside the parentheses, 9-1 and 6+3, which give us 8 and 9 respectively. Then we combine them into an ordered pair to get (8,9).

When we compare the two ordered pairs, we can see that the x-coordinates are the same, but the y-coordinates are different. Therefore, (8,8) is not equal to (9-1,6+3) and the statement "True or False(8,8) = (9-1,6+3)" is false.

Let's evaluate each side of the equation separately:

(8,8) represents an ordered pair with 8 as the x-coordinate and 8 as the y-coordinate.

(9-1, 6+3) evaluates to (8,9), since 9-1 = 8 and 6+3 = 9.

So we have:

(8,8) = (8,9)

This is a false statement, since the y-coordinates are different. Therefore, the answer is False.

The probability of selecting all three infielders is relatively low, with only a 1.73% chance of happening.

We can use the formula for probability of an event as the ratio of favorable outcomes to total outcomes. In this case, we want to find the probability that all three selected players are infielders, which means we need to select three infielders from the total number of players.

The total number of ways to select 3 players out of 24 (8 pitchers + 7 infielders + 9 other players) is given by the combination formula:

C(24, 3) = (24!)/(3!21!) = 2024

The number of ways to select 3 infielders out of 7 infielders is given by:

C(7, 3) = (7!)/(3!4!) = 35

Therefore, the probability that all 3 selected players are infielders is:

P(all 3 infielders) = favorable outcomes/total outcomes

= C(7, 3) / C(24, 3)

= 35/2024

= 0.0173 or 1.73%

So, the probability of selecting all three infielders is relatively low, with only a 1.73% chance of happening.

Answer:

a= 5.7

Step-by-step explanation:

Ok, when solving problems like this, it is important to do it step by step to minimize any mistakes.

Original Equation:

[tex]\frac{10a}{3} -1.5=17.5[/tex]

Then we add 1.5 to both sides

[tex]\frac{10a}{3} -1.5+1.5=17.5+1.5[/tex]

Simplify:

[tex]\frac{10a}{3}=19[/tex]

Multiply both sides by 3 to get rid of the denominator in the left side.

[tex]\frac{10a}{3} *3 = 19*3[/tex]

Simplify:

[tex]10a=57[/tex]

Divide both sides by 10 to isolate a

[tex]a = 5.7[/tex]

We can check our answer by plugging our value into the original equation!

Original equation:

[tex]\frac{10a}{3}-1.5=17.5[/tex]

New equation:

[tex]\frac{10(5.7)}{3}-1.5=17.5[/tex]

Multiply the numerator:

[tex]\frac{57}{3}-1.5=17.5[/tex]

Divide the fraction:

[tex]19-1.5= 17.5[/tex]

Subtract:

[tex]17.5=17.5[/tex]

as you can see, the values on both sides of the equation match.

So, a = 5.7

Answer:

x = 5 or -6

Step-by-step explanation:

We can find the zeros of the function:

[tex]y=x^2+x-30[/tex]

by setting y to 0, then solving for x.

To do this, we need to factor the right side of the equation.

[tex]0=x^2+x-30[/tex]

[tex]0=(x + 6)(x - 5)[/tex]

We can see that (x + 6) and (x - 5) are the two parts of this factorization because 6 and -5 add to 1 (which is the coefficient of the middle term), and they multiply to -30 (the constant term).

From this factored form, we can split the equation into two because we know that:

IF [tex]ab = 0[/tex],

THEN [tex]a=0[/tex]  OR  [tex]b=0[/tex]

So, we can solve for x in the following two equations:

[tex]x + 6 = 0[/tex]             [tex]x - 5 = 0[/tex]

[tex]\boxed{x = -6}[/tex]    OR   [tex]\boxed{x = 5}[/tex]

The probability of choosing a red marble followed by two blue marbles from the jar is 0.137 or approximately 13.7%.

The probability of choosing a red marble followed by two blue marbles from a jar containing 7 red, 5 green, 10 blue, and 3 yellow marbles.
To solve this problem, we need to first calculate the total number of possible ways to choose three marbles from the jar.

This is given by the combination formula:
nCr = n! / (r!(n-r)!)
Where n is the total number of marbles in the jar, and r is the number of marbles we want to choose.
Using this formula, we can find that the total number of ways to choose three marbles from the jar is:
nCr = 25! / (3!22!) = 2300
Next, we need to calculate the number of ways to choose a red marble followed by two blue marbles.

We can do this by using the multiplication principle of counting:
Number of ways to choose a red marble = 7
Number of ways to choose two blue marbles = 10C2 = 45
Total number of ways to choose a red marble followed by two blue marbles = 7 * 45 = 315
Finally, we can calculate the probability of choosing a red marble followed by two blue marbles by dividing the number of ways to choose a red marble followed by two blue marbles by the total number of possible ways to choose three marbles from the jar:
P(red, blue, blue) = 315 / 2300 = 0.137

Given that, a bus and a car have speed of 100km/hr and 120km/hr.

They are covering a distance of 340 km, they started travelling at 7:00 am,

Speed = distance / time

A) Bus travelled in 30 minutes = 100 × 0.5 = 20 km

After 30 minutes = 100 × 0.5 = 20 km

Total distance by bus in 1 hour = 40 km

Car covered in 30 minutes = 120 × 0.5 = 60 km

Distance between them = 60-40 = 20 km

Relative speed = 120-100 = 20 km/h

Time to catch up = 20/20 = 1 hour

Distance from Nairobi = 60 + (1 × 120) = 180 km

Therefore, the car catches up with the bus 180 km from Nairobi,

B) Time taken = 30 + 30 + 1 = 2 hours.

Answer: 24 - Rectangle 1

Step-by-step explanation:

The two Rectangle 1's are the top and bottom rectangles. To find the area of a rectangle, you have to multiply length x width. You know that the bottom rectangle is identical to the top rectangle, so by solving for the bottom rectangle, we solve for the top!

The length of this rectangle at the bottom is 8, and the width is 3. 8 x 3 = 24. The area of the bottom and top rectangles (1) are 24.

The question wants you to multiply one rectangle with an area of 24 feet squared by 2, because there are two of the same rectangles (top and bottom). 24 x 2 = 42. The total area of the top and bottom rectangles is 42 square feet.

You can do the same with the other rectangles. Using length x width = area, you can then multiply that times two to get the area of two of the same rectangles. Here's one more example from the problem:

The largest rectangle from the rectangular prism is facing the front, the other is facing the back. The length of these two rectangles is 15, the width is 8.

length x width = area
15 x 8 = area

120 square feet = area

Now, multiply that by 2 and you get the area of both of the same rectangles. 240 square feet.

Now we have Rectangle 1 (x2) = 42, and another Rectangle (2 or 3) (x2) = 240. Now, all you have to do is find the area of the rectangle with the length of 15 and the width of three and multiply it by two to find the areas of all the triangles. Then, save all three answers: 42, 240, and the other answer. Then, add 42, 240, and the other answer together to get the Total Surface Area. Good luck!

The equation of the parabola in vertex form is y = (1/20)(x + 7)^2 + 1.

To write the equation of a parabola in vertex form, we use the equation:

y = a(x - h)^2 + k

where (h, k) represents the vertex of the parabola.

Given that the vertex is (-7, 1), we have h = -7 and k = 1. Substituting these values into the equation, we get:

y = a(x + 7)^2 + 1

Now, we need to find the value of 'a' to complete the equation. Since the parabola passes through the point (10, 309/20), we can substitute these coordinates into the equation:

309/20 = a(10 + 7)^2 + 1

309/20 = a(17)^2 + 1

309/20 = a(289) + 1

309/20 = 289a + 1

To simplify the fraction, we multiply both sides by 20:

309 = 20(289a + 1)

309 = 5780a + 20

Now, we solve for 'a':

5780a = 309 - 20

5780a = 289

a = 289/5780

a = 1/20

Substituting this value of 'a' back into the equation, we have:

The seventh-grade class supplied 175 bags of snacks and 225 beverages for the school dance.

Finding the number of bags of snacks and beverages:

Let's assume that the number of bags of snacks supplied by the seventh-grade class is represented by 'x'. Since the number of beverages supplied is 50 more than the number of bags of snacks, we can represent the number of beverages supplied as 'x + 50'.

The total number of items supplied is 400, so we can write:

x + (x + 50) = 400

Simplifying this equation, we get:

2x + 50 = 400

Subtracting 50 from both sides, we get:

2x = 350

Dividing both sides by 2, we get:

x = 175

Therefore, the number of bags of snacks supplied by the seventh-grade class is 175. Using the fact that the number of beverages supplied is 50 more than the number of bags of snacks, we can calculate the number of beverages supplied as:

x + 50 = 175 + 50 = 225

Therefore, the number of beverages supplied by the seventh-grade class is 225.

So, the seventh-grade class supplied 175 bags of snacks and 225 beverages for the school dance.
