Step-by-step explanation: Take 80 and divide it by 192.0= .416666667

The probability of both sprouts blooming under the best conditions is 16 percent.

The probability that two sprouts will both bloom under the best conditions can be calculated using the formula P(A and B) = P(A) * P(B), where P(A) and P(B) are the probabilities of each sprout blooming. Assuming that each sprout has an independent probability of blooming of 0.5, then the probability of both sprouts blooming is 0.5 * 0.5 = 0.25, or 25%. This can also be expressed as a proportion of 1/4, or a percentage of 25%.

In other words, if two sprouts are selected at random, then the probability that both will bloom, under the best conditions, is 25%. This can also be expressed as a probability of 1 in 4, or 16%. This means that out of 4 sprouts, on average, one will bloom, and the other three will not. Therefore, the probability of both sprouts blooming under the best conditions is 16 percent.

Answer:

y = - 5/4x -12

Step-by-step explanation:

Original slope= (0- -4)/(5-0)=4/5

slope of perpendicular line of original = -5/4

so the line passes through the point (-8,-2)

(y - -2) = -5/4 (x - -8)

y + 2 = -5/4x - 10

y = - 5/4x -12

The equation of line u passing through the point (-8, -2) and which is perpendicular to the line y that cut the x-axis at x = 5 and y-axis at y = -4 is 5x + 4y + 18 = 0

Given that line, u passes through (-8,-2) and is perpendicular to line y

line y cut x-axis at x=5 and y-axis at y=-4

that is the point of intercept are : (x1, y1) = (5,0) and (x2, y2) = (0, -4)

Now, the equation of line = (y - y1) = m1*(x - x1)

Here m is the slope of line y

m1 = (y1 - y2)/(x1 - x2)

On solving,

m1 = (0 - (-4))/(5 - 0) = 4/5

We know that when two equations are perpendicular then the multiplication of their slopes = -1

m1 * m2 = -1

Now, m2 = -1/m1 = -5/4

Equation of line u passing through the point (-8, -2) and perpendicular to the line = (y - y1) = m2*(x - x1) =>  (y - (-2)) = -5/4*(x - (-8)

5x + 4y + 18 = 0

Answer:

[tex]f^{-1}[/tex](x) = [tex]\sqrt{x+11}[/tex] + 4, x=-11

Step-by-step explanation:

y = x^2 - 8x + 5, x<=4

x = y^2 - 8y + 5, y<=4  ==> switch the x and y variables to find the inverse

x = y^2 - 8y + 5  ==> solve for y

x + 16 = y^2 - 8y + 16 + 5  ==> add 16 to get a perfect polynomial square

x + 16 = (y - 8/2)^2 + 5  ==> simplify

x + 16 = (y - 4)^2 + 5

x + 16 - 5 = (y - 4)^2 + 5 - 5  ==> isolate y by subtracting 5 on both sides

x + 11 = (y - 4)^2  ==> simplify

[tex]\sqrt{x+11}[/tex] = [tex]\sqrt{(y - 4)^2}[/tex]  ==> take the square root of both sides to remove the

                                        square

[tex]\sqrt{x+11}[/tex] = y - 4

y = [tex]\sqrt{x+11}[/tex] + 4  ==> add 4 on both sides to isolate y

[tex]f^{-1}[/tex](x) = [tex]\sqrt{x+11}[/tex] + 4  ==> substitute [tex]f^{-1}[/tex](x) for y

[tex]f^{-1}[/tex](x) = [tex]\sqrt{x+11}[/tex] + 4, [tex]f^{-1}[/tex](x)<=4  ==> add in the domain restriction

4 = [tex]\sqrt{x+11}[/tex] + 4  ==> plugin the domain restriction for [tex]f^{-1}[/tex](x)

0 = [tex]\sqrt{x+11}[/tex] ==> subtract 4 on both sides

x + 11 = 0  ==> the square root of 0 is 0

x = -11  ==> subtract 11 on both sides

Hence, answer is: [tex]f^{-1}[/tex](x) = [tex]\sqrt{x+11}[/tex] + 4, x=-11

Answer:

y = -3x + 6

Step-by-step explanation:

According to the information given, your two points are (2, 0) and (4, -6).

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(-6 - 0) / (4 - 2)

Simplify the parentheses.

= (-6) / (2)

Simplify the fraction.

-6/2

= -3

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = -3x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (4, -6). Plug in the x and y values into the x and y of the standard equation.

-6 = -3(4) + b

To find b, multiply the slope and the input of x(4)

-6 = -12 + b

Now, add 12 to both sides to isolate b.

6 = b

Plug this into your standard equation.

y = -3x + 6

This is your equation.

Check this by plugging in the other point you have not checked yet (2, 0).

y = -3x + 6

0 = -3(2) + 6

0 = -6 + 6

0 = 0

Your equation is correct.

The complete question is -

How do you find the mean of 20 natural numbers?

Answer:

To express the quadratic expression x^2 - 5x + 8 in the form of (x - a)^2 + b, we need to complete the square. To do this, we can add and subtract the square of half the coefficient of the x term. In this case, that would be (1/2)(-5) = -5/2. Therefore, we add and subtract (1/2)(-5)^2 = (-5/2)^2 = 25/4 to get:

x^2 - 5x + 8 = (x^2 - 5x + (25/4)) + (8 - (25/4))

Next, we need to add and subtract 25/4 in such a way that we can factor the quadratic expression as the square of a binomial. To do this, we add 25/4 to the first term and subtract 25/4 from the second term to get:

x^2 - 5x + (25/4) + (8 - (25/4)) = (x^2 - 5x + 25/4) + (8 - 25/4)

Now we can factor the quadratic expression as the square of a binomial:

(x^2 - 5x + 25/4) + (8 - 25/4) = (x - 5/2)^2 + (8 - 25/4)

Therefore, we can express x^2 - 5x + 8 in the form of (x - a)^2 + b where a is -5/2 and b is 8 - 25/4.

Note that the values of a and b are not whole numbers because we added and subtracted a fraction when completing the square.

Yes , SAS (Side-Angle-Side) is a second Congruence postulate to prove triangle congruence by showing that two sides and their included angles are congruent.

Side-Angle-Side is the rule used to prove whether a given set of triangles are congruent. The SAS rule states: Triangles are congruent if two sides and an included angle of a triangle are equal to two sides and an included angle of another triangle. An included angle is the angle formed by two given sides.. For example : let's us consider two triangles ∆SQR and ∆TSR ,

In above given figure, sides

RS = RS ( common side)

QS = ST ( S divides QT in two equal parts) and angle between QS and SR equal to angle between SR and ST i.e. ∠QSR = ∠RST = 90° (right angle ) and it is included angle . So, by SAS Congruence rule, both of triangles are congruent. Hence, Δ ABC ≅ Δ PQR.

A quadratic inequality of the form

A quadratic inequality of the form

y>a[tex]x^{2}[/tex]+bx+c

(or substitute <,≥ or ≤ for > ) represents a region of the plane bounded by a parabola .

To graph a quadratic inequality, start by graphing the parabola. Then fill in the region either above or below it, depending on the inequality.

If the inequality symbol is ≤ or ≥ , then the region includes the parabola, so it should be graphed with a solid line.

Otherwise, if the inequality symbol is < or > , the parabola should be drawn with a dotted line to indicate that the region does not include its boundary.

Example:

Graph the quadratic inequality.

y≤[tex]x^{2}[/tex]−x−12

The related equation is:

y=[tex]x^{2}[/tex]−x−12

First we notice that a , the coefficient of the [tex]x^{2}[/tex] term, is equal to 1 . Since a is positive, the parabola points upward.

The right side can be factored as:

y=(x+3)(x−4)

So the parabola has x -intercepts at −3 and 4 . The vertex must lie midway between these, so the x -coordinate of the vertex is 0.5 .

Plugging in this x -value, we get:

y=(0.5+3)(0.5−4)

y=(3.5)(−3.5)

y=−12.25

So, the vertex is at (0.5,−12.25) .

The  probability of the card being an ace, given that it is a non-face card is option A: 8% .

To find the probability of an event occurring, we can use the formula:

Probability = number of ways the event can occur / total number of outcomes.

In this case, we are trying to see the probability of drawing an ace from a standard deck of 52 cards, given that the card is a non-face card. There are 4 aces in a standard deck of 52 cards, so the number of ways the event (drawing an ace) can occur is 4. There are 52 total cards in the deck, and 48 of them are non-face cards. So, the total number of outcomes is 48.

Therefore, the probability of the card being an ace, given that it is a non-face card, is 4/48.

4/48 = 0.083

Find the vector A. Find the vector B.

We may disregard the vector x and treat the issue as an arithmetic one since all of the measurements are in the same direction (simultaneous equations).

A − B = −51.4.............................(1)

C = 62.2.............................(2)

A + B + C = 13.8.............................(3)

Now putting the value of C from Equation (2) in Equation (3)

A + B + C = 13.8

A + B + 62.2 = 13.8

Subtract 62.2 on both side, we get

A + B = 13.8 - 62.2

A + B = - 48.4.....................(4)

Adding the equation (1) and (4), we get

2A = - 99.8

Divide by 2 on both side, we get

A = - 49.9

Now subtracting the equation (1) and (4), we get

2B = -48.4 - ( -51.4)

2B = 3

Divide by 2 on both side, we get
