Step-by-step explanation:

Since we have given that

There are three person : Joe, Keitaro, Luis.

And two names will be selected for he game .

Possible events will be

But we want to find the complement of the event in which Joe plays in hte first match,

As we know that complement of any events means eliminate that event from the universal set.

Event of getting Joe plays in the first match is given by

So, complement of this event that Joe plays in the first match is given by

The possible events are:

{JK, JL, KL}

The events where J does not play (the first game) are: {KL}

Answer: A = {KL}

The complement of the event in which Joe plays in the first match is {KL} and the subset of the sample space is {JK, JL, KL}

Complementary events are two events that exist such that one event will occur if and only if the other does not take place.

Given that, Joe, Keitaro, and Luis play tennis. To decide who will play against each other in the first match, they put their names in a hat and choose two names without looking.

There are three persons: Joe, Keitaro, Luis.

There are two names to be selected for the game.

Possible events will be = {JK, JL, KL}

But we want to find the complement of the event in which Joe plays in the first match,

As we know that complement of any events means to eliminate that event from the universal set.

Event of getting Joe plays in the first match is given by = {JK, JL}

So, the complement of this event that Joe plays in the first match is given by = {KL}

Hence, the complement of the event in which Joe plays in the first match is {KL} and the subset of the sample space is {JK, JL, KL}

Step-by-step explanation:

Answer:

1 3/4

Step-by-step explanation:

Find a common denominator for both fractions

9 1/12 - 7 4/12 = 1 9/12 = 1 3/4

Answer:

34

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ 1, 6 ]

f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162

f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8, thus

average rate of change = [tex]\frac{162-(-8)}{6-1}[/tex] = [tex]\frac{170}{5}[/tex] = 34

Final answer:

The average rate of change of the function f(x) = x^3 - 9x over the interval (1,6] is 34.

Explanation:

The average rate of change of a function f(x) over an interval is calculated by taking the difference in the function values at the end points of the interval divided by the length of the interval. For the function f(x)=x^3-9x over the interval (1,6], we calculate the function values at x=1 and x=6, then find the difference, and divide by the interval length, which is 6-1=5. So f(1)=1^3-9(1)=-8 and f(6)=6^3-9(6)=216-54=162. Therefore, the average rate of change is (162-(-8))/5 = 170/5 = 34.

I used the the distance formula.

Answer:

a. (-3, 2).

b.  √65

c.  (x + 3)^2 + (y - 2)^2 = 65

Step-by-step explanation:

a.  The center is the midpoint  of the diameter PQ.

= (-10+4)/2, (-2+6)/2

= (-3, 2).

b. The radius is the distance from the center to a point on the circle.

Take the point (4, 6):

The radius = √((-3-4)^2 + (2-6)^2)

= √65.

c.  The equation of the circle is:

Using the standard form

(x - h)^2 + (y - k)^2 = r^2  where  (h, k) is the center and r = the radius:

it is (x - (-3)^2 + (y - 2) = 65

= (x + 3)^2 + (y - 2)^2 = 65.

Answer:

a. (-3,2)

b. sqrt(65)

c. (x + 3)² + (y - 2)² = 65

Step-by-step explanation:

Centre:

midpoint of the diameter

(h,k) = (-10+4)/2, (-2+6)/2

(h,k) = (-3,2)

Length of the diameter:

sqrt[(-2-6)² + (-10-4)²]

sqrt(260)

2sqrt(65)

Radius: ½ × diameter

Radius = sqrt(65)

Equation:

(x - h)² + (y - k)² = r²

(x - -3)² + (y - 2)² = (sqrt(65))²

(x + 3)² + (y - 2)² = 65

The greatest number of crates that a crane with a breaking strain of 6400 kg can safely lift at one time (with the crate weight marked to the nearest 90 kg) is 71 crates.

In this problem, we need to determine the maximum number of crates a crane can lift without breaking its cable. The breaking strain of the cable can be interpreted as the maximum weight, or load, the cable can safely support. This is given as 6400 kg. Each crate the crane is lifting is said to weigh 90 kg.

To find the maximum number of crates that can be safely lifted, we divide the breaking strain (the total load the cable can bear) by the weight of each individual crate. Therefore:

6400 kg (total load) / 90 kg (load per crate) = 71 crates

However, since we can't lift fractions of a crate, we should round down to the nearest whole number, which gives us a maximum of 71 crates that can be lifted safely without the cable breaking.

To find the maximum number of crates that can be lifted without exceeding the cable's breaking strain of 6400 kg, divide the breaking strain by the weight of one crate (90 kg) and round down to the nearest whole number, which results in 71 crates.

To determine the greatest number of crates that a crane cable with a breaking strain of 6400 kg can lift at one time, you perform a simple division. The weight of each crate is given as 90 kg (measured to the nearest 10 kg).

To ensure safety, you take the total breaking strain of the cable and divide it by the weight of one crate:

Breaking strain of cable = 6400 kg

Number of crates = Breaking strain of cable / Weight of one crate

Number of crates = 6400 kg / 90 kg/crate

Number of crates = 71.111...

Since you cannot lift a fraction of a crate, round down to the nearest whole number.

The greatest number of crates that can be lifted without breaking the cable is 71 crates.

For 96 minutes the candles were burning if two candles of equal height start to burn simultaneously.  

It is defined as the change in values of a dependent variable with respect to the independent variables.

W have:

Rate of burning for thicker = h/4

Rate of burning for thinner= h/2

remaining part = h - ht/4

remaining part = h - ht/2

h - ht/4 = 3(h - ht/2)

After solving for t:

t = 8/5 hours

or

t = 96 minutes

Thus, for 96 minutes the candles were burning if two candles of equal height start to burn simultaneously.

Answer:

10 divided by 4 is 2.5 inch. so 3 inches is longer then 10/4

Step-by-step explanation:

Answer:

Explanation:

To estimate the value, you can work with friendly numbers: numbers closed to the given numbers and with which you can perform easy mental calculations.

For example 4.55 may be rouned to 5, 4.85 may be rounded to 5, and 3.25 may be rounded to 3. That yields 5 + 5 + 3 = 13

Then, it seems you have about 13 liters. Is the final number equal or greater than 12 for sure?

To round 4.55 to 5 you increased the amount in 0.45, to round 4.85 to 5 you increased the amount by 0.15, and to round 3.25 to 3 you decreased the amount in 0.25.

What was the net change in your values: 0.45 + 0.15 - 0.25 = 0.60 - 0.25 = 0.35. Those are easy calculations that you can perform in your mind.

That means that you increased your total in less than 1 liter. Meaning that the final total is overestimated by 0.35, and that if you used the real amounts to make the calculations, the total will be still more than 12.

The value of the smaller number is 4.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let's start by translating the given information into equations.

We can use variables to represent the two numbers, and use the given information to write equations in terms of those variables.

Let x be the smaller number.

Then the larger number is 6 more than x, which we can write as (x + 6).

Twice the larger number is 5 times the smaller, which we can write as:

2(x + 6) = 5x

Now we can solve for x:

2x + 12 = 5x

Subtracting 2x from both sides, we get:

12 = 3x

Dividing both sides by 3, we get:

x = 4

Therefore,

The smaller number is 4.
