The probability that exactly one tank in the sample contains high-viscosity material is P(A) = 0,4607 or P(A) = 46,07 %

P(A) = Number of favorable events/ Total number of events FE/TE

If A and B are complementary events ( the sum of them is equal to 1) then:

P(A) = 1 - P(B)

The total number of events is:

C ( 24,4) = 24! / 4! ( 24 - 4 )!    ⇒  C ( 24,4) = 24! / 4! * 20!

C ( 24,4) = 24*23*22*21*20! / 4! * 20!  

C ( 24,4) = 24*23*22*21/4*3*2C ( 24,4) = 24*23*22*21/4*3*2    ⇒  C ( 24,4) =  10626

TE = 10626

Splitting the group of tanks in two 6 with h-v  and 24-6 (18) without h-v

we get that total number of favorable events is the product of:

FE = 6* C ( 18, 3)  = 6 * 18! / 3!*15!  =  18*17*16*15!/15!

FE =  4896

Then P(A) ( 1 tank in the sample contains h-v material is:

P(A) = 4896/10626

P(A) = 0,4607     or   P(A) = 46,07 %

A kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other.

The given figure is a kite with two intersecting lines that are perpendicular to each other.

Since the lines are perpendicular to each other, hence;

m<1 = 90 degrees

For the measure of m<2

m<2 + 90 + 27 =180

m<2 + 117 = 180

m<2 = 180 - 117

m<2 = 63degrees

Since the opposite sides are congruent, hence the measure of m<2 is congruent to m<3. Hence m<3 = 63 degrees

Answer:

30

Step-by-step explanation:

Let's start by multiplying the equation through bt the least common denominator so that we can clear the denominator:

[tex]\frac{2}{5}x+\frac{1}{3}y=1[/tex]

The least common of 3 and 5 is 15, so we can multiply through by 15:

[tex]15(\frac{2}{5}x+\frac{1}{3}y)=15(1)\\6x+5y=15[/tex]

We want the left side of the equation to be 12x + 10y. We can get this if we multiply the expression we currently have (6x + 5y) by 2. However, if we multiply the left side by 2, we must also multiply the right side by 2 to balance out the equation. If we do this, we will get our answer:

[tex]2(6x+5y)=2(15)\\12x+10y=30[/tex]

On the right side, we get 30. Therefore, the answer is 30

The points are (-1, 1) and (5, 5).

So, the difference in the y coordinates is [tex]5-1=4[/tex].

The net change between the x-coordinates and y-coordinates on the graph is 6 units and 4 units respectively.

The coordinates from the given graph are (5, 5) and (-1, 1).

Given two points, (a, f(a)) and (b, f(b)) on the graph of f(x), the net change is the difference between the two f(x) values. Thus, net change is given by f(b)−f(a).

Here, the change in x-coordinates is 5-(-1) = 6

The change in y-coordinates is 5-1 = 4

Therefore, the net change between the x-coordinates and y-coordinates on the graph is 6 units and 4 units respectively.

Answer:

[tex]y = -3x+4[/tex]

I hope this helps and that you can give a brainliest!

Step-by-step explanation:

A linear equation means that the y value changes at a constant rate as x increases by 1.

To find the rate of change you need to plug 2 ordered pairs into the formula:
[tex]\frac{y1-y2}{x1-x2}[/tex]

(x1,y1) can be any data point on this table. To make it easy, we will make it (2,-2).

(x2,y2) can be any data point other than the previously chosen point. So, we will choose (-1,7).

If we substitute this into the formula, previously mentioned, we get:

[tex]\frac{-2-7}{2-(-1)}[/tex]

When we solve this, we get the rate of change as -3.

This will be the "m" value in the linear equation format:
"y = mx+b"

The b value is the y-value of the data when x = 0.

So to get the b-value, you need to plug in one ordered pair into the "y=mx +b" equation.

"m" was the rate of change, which we found in the previous step.

Let's use (2,-2) as the chosen ordered pair.

By substitution, we end up with:
[tex]-2=-3(2)+b[/tex]

If we solve this out, we get:
[tex]b = 4[/tex]

m was -3 and b is now 4.

So, putting this into the equation "y = mx+b"
We get our answer as [tex]y=-3x+4[/tex].

Answer:

30.

Step-by-step explanation:

2 digit Numbers which  have factor of  2:

2*3, 2*5, 2*7, 2*11, 2*13, 2*17, 2*19, 2*23, 2*29, 2*31, 2*37, 2*41, 2*43, 2*47.

That's 14.

Then there are the ones with factor 3:

3*5 ....... 3*31 = 9 numbers.

Then

5*7  to 5*19 = 5 numbers.

7*11 , 7*13 = 2 numbers.

Total is 14 + 9 + 5 + 2

=  30.

There are 30 2-digit numbers that are the product of two different primes.

To determine the number of 2-digit numbers that are the product of two different primes, we first need to identify the primes within the range of 10 to 99. The prime numbers within this range are 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97.

To find the count of 2-digit numbers that are the product of two different primes, we can consider all possible pairs of these primes.

The numbers that yield 2-digit numbers with a multiple of 2 are:

(2, 5), (2, 7), (2, 11), (2, 13), (2, 17), (2, 19), (2, 23), (2, 29), (2, 31), (2, 37), (2, 39), (2, 41), (2, 43), (2, 47).

Total = 14

The numbers that yield 2-digit numbers with a multiple of 3 are:

(3, 5), (3, 7), (3, 11), (3, 13), (3, 17), (3, 19), (3, 23), (3, 29), (3, 31).

Total = 9

The numbers that yield 2-digit numbers with a multiple of 5 are:

distinct: (5, 7), (5, 11), (5, 13), (5, 17), (5, 19).

Total = 5

The numbers that yield 2-digit numbers with a multiple of 7 are:

Distincts: (7, 11), (7, 13)

Total = 2

Therefore, the total numbers of pairs are 14 + 9 + 5 + 2 = 30.

According to the question,

Alice and Bob each arrive at a party at a random time between 1.00 P.M and 2.00 P.M.

In probability theory, the sample space(s) of a random trial is the set all possible results of that trial.

s = {(x, y) /1≤x≤2 and 1≤y≤2}

Answer:

y = -3x - 28

Step-by-step explanation:

y = mx + b is the slope-intercept of a line.  To write an equation in this form.  I need to find the slope (m) and the y-intercept (b).  Yay!  They gave us the slope (m).  It is -3.  Now we just need to figure out the y.  We can do that by plugging in the slope (-3) and using the x (-8) and the y (-4) that they gave us from the point to solve for b.

y = mx + b

-4 = -3(-8) + b  Multiple -3(-8) Remember a negative times a negative is a positive.

-4 = 24 + b  Now subtract 24 from both side of the equation

-28 = b  Now we can write the equation

y = mx + b

y = -3x + (-28) or y = -3x -28.  Adding a negative is the same as subtracting a positive.

Using the together rate, it is found that it would take each person working individually 27 and 29 hours to paint the house.

The together rate is the sum of each separate rate.

In this problem, we have that the rates are given as follows:

Hence:

[tex]\frac{1}{d} + \frac{1}{d - 2} = \frac{1}{14}[/tex]

[tex]\frac{d - 2 + d}{d(d - 2)} = \frac{1}{14}[/tex]

d² - 2d = 28d - 28.

d² - 30d + 28 = 0

(d - 29)(d - 0.96) = 0.

Both d and d - 2 have to be positive, hence the solution is d = 29, and it would take each person working individually 27 and 29 hours to paint the house.

           - B  ±  √ B2-4AC

 x =   ————————

 In our case,  A   =     3

                     C   =   -1

 B2  -  4AC   =
