The probability that the bolt will be inserted in 19 minutes or less is 0.8413.

It should be noted that the probability will be illustrated as:

P(X < x) = P[z < (x - u/sd)]

where

x = number

u = mean

SD = standard deviation

Therefore given the numbers, this will be:

P(x < 19) = P(z < (19 - 15)/4)

= P(z < 4/4) = P(z < 1)

= 0.8413

Therefore, the probability that the bolt will be inserted in 19 minutes or less is 0.8413.

A difference quotient that best approximates the instantaneous rate of change of g at x=2.5 is; -3

We can define the average rate of change of a function g(x) in an interval [a, b] as:

r = [g(b) - g(a)]/(b - a)

Particularly, if we want to find an approximation of the rate of change for a particular value x', we can choose:

a < x' < b

Such that a and b are really close to x'.

Then if we want to find the instantaneous rate of change of g at x = 2.5, we need to find values of a and b really close to 2.5.

Looking at the graph, we can choose:

a = 2

b = 3

(are the two closer ones to 2.5)

Then the rate of change can be written as:

f'(x) = g(3) - g(2)]/(3 - 2)

f'(x) = (1 - 4)/1

f'(x) = -3

Thus, we can conclude that a good approximation of the instantaneous rate of change is -3.

Answer:

$5.11

Step-by-step explanation:

3.6 x 1.42 = 5.112

Step-by-step explanation:

(4h⁴)⁴ / (4h^-8)

remember, multiplying exponents means adding them. exponents of exponents means multiplying them.

and dividing exponents means subtracting them.

also, n^-a = 1/(n^a).

let's look at the numerator (top part) first :

(4h⁴)⁴ = 4^1×4 × h^4×4 = 4⁴×h¹⁶

now, for the denominator, the exponent -8 applies only to h. not to 4.

so,

1/(4h^-8) = h⁸/4

and so, the whole expression is then simplified

4⁴×h¹⁶ × h⁸/4 = 4³ × h²⁴

The area of triangle ABC when Angle B=120°, AB= 6, BC = 10 is 25.980 square unit.

As per the question statement, we are supposed to find out the area of triangle ABC in which angle B=120°, AB= 6, BC = 10.

Lets find out AC for which we should know about Cosine formula

i.e., [tex]AC^{2} =AB^{2} +BC^{2} -2(AB)(BC)cos(B)\\AC^{2} =6^{2} +10^{2} -2*6*10cos120\\AC^{2}= 36+100-120*(-0.5)\\AC^{2}=196\\AC=\sqrt{196} =14[/tex]

Hence We have measures of all three sides of the triangle ABC.

Now we use the Heron's formula for calculating the area of triangle ABC.

We need semi perimeter i.e., [tex]s=\frac{AB+BC+AC}{2}[/tex]

[tex]s=\frac{30}{2} =15[/tex]

Now Area is given by,

[tex]area=\sqrt{s(s-AB)(s-BC)(s-AC)} \\area=\sqrt{15(15-6)(15-10)(15-14)} \\area=\sqrt{15*9*5*1} \\area=\sqrt{675} \\area = 25.980 unit^{2}[/tex]

Answer:Answer:

The measurement of the angle is 60

Step-by-step explanation:

The two blue lines are straight and parallel lines. The sum of the angles on a straight line is 180 degrees. Angle 5 and angle 6 are on a straight line. Therefore

Angle 5 + angle 6 = 180

If angle 5 is 120 degrees, then

Angle 6 = 180 - 120 = 60 degrees.

According to the question, the given data for the scalar projection calculation represent the point [tex]P1(x1,y1)[/tex] to the line [tex]ax1+by1+c=0.[/tex]

What is scalar projection?

Scalar projection refers to scalar coordinates in the cartesian coordinates. It is also the length of the vector projection. It is calculated with the help of the dot product with the unit vector direction. It always tells about the magnitude of the projection.

By using scalar projection, calculate the distance from the point [tex]P1[/tex] to the line.

Here,[tex](a, b)[/tex] is perpendicular and the equation can be written as

           [tex]by1 = -ax1-c[/tex]    

          [tex]y1 = -\frac{a}{b}x1-c[/tex]

For this the slope of the given equation can be written as: [tex]-\frac{a}{b}[/tex]

And the distance is : [tex]d = \frac{|ax1+by1+c|}{\sqrt{a2+b2} }[/tex].

Therefore, the calculated distance for the given equation is:[tex]d = \frac{|ax1+by1+c|}{\sqrt{a2+b2} }[/tex]

The correct option is a) x = negative two fifths. The value of x is obtained by solving it with rules of linear equation in two variable as x = -2/5.

A linear equation in one variable is an equation that has only one solution and is expressed in the form ax+b = 0, where a and b are two integers and x is a variable. 2x+3=8, for example, is a linear equation with a single variable.

Now, as per the given expression;

                                2/3(x -2) = 4x

Multiply both sides of equation by 3.

                                2(x - 2) = 12x

Simplifying;

                                2x - 4  = 12x

Subtract 2x on both sides of the equations.

                                -4 = 12x - 2x

Again Simplifying;

                               -4 = 10x

Divided by 10 on both sides

                                x = -4 / 10

                                x = -2/5

Therefore, the value of x is obtained as x = -2/5.

The equation of the perpendicular bisector of the segment with the endpoints located at D(-2 , 4) and E(3 , 5) is y = -5x + 7

A perpendicular bisector of a segment is a line that divides the segment into two equal parts forming right angles at the point of intersection.

To get the perpendicular bisector of a segment, get the point of intersection of the two lines which is the midpoint of the segment.

midpoint (x , y) = [(x1 + x2)/2 , (y1 + y2)/2]

midpoint (x , y) = [(-2 + 3)/2 , (4 + 5)/2]

midpoint (x , y) = (1/2 , 9/2)

Get the slope of the perpendicular bisector of a segment by taking the negative reciprocal of the slope of the segment.

slope of segment = (y2 - y1)/(x2 - x1)

slope of segment = (5 - 4)/(3 - -2)

slope of segment = 1/5

slope of the perpendicular bisector = -5

Solving for the y-intercept, b, plug in the point (1/2 , 9/2) and the slope -5 to the slope-intercept form of the equation, y = mx + b.

y = mx + b

9/2 = -5(1/2) + b

b = 7

Setting up the equation in slope-intercept form, where m = -5 and b = 7.
