In a batch of 8000 clock radios 5% are defective. A sample of 13 clock radios is randomly selected without replacement from the 8,000 and tested. The entire batch will be rejected if at least one of those tested is defective. What is the probability that the entire batch will be rejected

Answers

Answer 1

Answer:

Step-by-step explanation:

P(A)=1−P(not A)

We can use this here. Event A is that the clock is defective, so Event (not A) means the clock works.

0.02=1−P(not A)

P(not A)=0.98

Therefore, for all the clocks to pass, the probability is P(not A)11.

Now again, we can use complementary counting.

(probability of all clocks failing) = 1 - (probability of all clocks passing)

Probability of all clocks failing = 1−P(not A)11

write the equation of the line perpendicular to the given line y= -2/3 x + 1

Answers

since the equation of the line passing through the given point is perpendicular to the given line(m2= -1/m1)

using the formula y=mx+c

y=2/3x +1

m1=2/3

m2= -1/2/3

m2= -3/2

the slope of the second line is -3/2 and it passes through the point(3,-2)

using the formula y-y1 = m(x-x1)

y-(-2)= -3/2(x-3)

y+2= -3/2(x-3)

multiply both sides by 2

2(y+2) = -3(x-3)

2y+4 = -3x+9

2y = -3x+5

y= -3/2x + 5/2

Answer:

x=120°

Step-by-step explanation:

X+X+1/2X+1/2X=360

combine all like variables

X+X=2X

1/2X+1/2X=X

2X+X=3X

What is 1 way you can tell if two people are paying the same rate?

Answers

Answer:

By saying "paying the same rate"

I believe you want to know for example when two people are buying a product how to know if they are paying the same amount.

If so then there are a couple of factors at play.

First of all you need to identify the GDP of the product and the amount of tax/VAT which if calculated properly may help you tell if they are paying the same amount or not.

A line segment is defined by which of the following statements?
А Two rays that share a common endpoint.
B.
The set of all points that are a fixed distance from a given point.
С
All points between and including two given points.
D
A straight path connecting two points and extending infinitely in both directions.

Answers

The only given option that correctly defines a line segment is;

Option C; All points between and including two given points.

      In geometry in mathematics, a line segment is defined as a part of a line that is bounded by two distinct end points.

Now, let us look at the options;

Option A; This is not correct because a line segment must have 2 distinct endpoints

Option B; This is not correct because a line segment is a part of a line and not a set of points.

Option C; This is correct because it tallies with our definition of line segment.

Option D; This is not correct because a line segment does not extend infinitely.

Answers

Answer:

Step-by-step explanation:

2(m+2) = 22

Using the distributive property, you can multiply the 2 to both the "m" term and the "2".

2m + 2*2 = 22

2m + 4 = 22

Then you isolate the variable and solve.

2m = 22 - 4

2m = 18

m = 9

2(m + 2) = 22

2(m) + 2(2) = 22

2m + 4 = 22

2m = 22 - 4

2m = 18

2m / 2 = 18 / 2

m = 9

To distribute the 2 to each term inside the parentheses means to multiply the 2 by both terms in the parentheses so

2(m + 2) means (2 × m) + (2 × 4)

which graph represents the equation y=-4/3x-2

Answers

Answer:Y = 3x2+ 4

When equation is in the form of y = Ax2 + Bx + C, it is in standard form.

A = 3, B = 0

Since A is positive, the graph opens upward.

Vertex is the lowest point on the graph.

The x coordinate of the vertex occurs at -B/2A

X =-B/2A = -0/2(3) = 0

To find the y-coordinate, we substitute 0 and solve for y

Y = 3(0)2 + 4 = 4

The vertex is at (0,4) ... the lowest point on the graph

From here, you can construct a table of values for x, and solve for y to obtain points on the graph.

Good x values to pick are -2, -1, 1, and 2

The domain is all the x-values for which the function is defined, The function is defined for all real values of x.

The domain is all real numbers. { x | x is a real number }

The range is all the y values obtained from input of the x-values.

The smallest y value is 4, the largest is positive infinity.

The range is all real numbers ≥ 4. { y | y ≥ 4 }

What force would have been applied to the bus from t=16 s to t=21 s? Assume the mass of the bus was 50 kg.

Answers

Applying Newton's Second Law, it is found that the force, in Newtons, is given by:

[tex]F = 10[v(21) - v(16)][/tex]

Newton's Second Law states that Force, in Newtons, is mass times acceleration, that is:

[tex]F = ma[/tex]

In this problem, mass of 50 kg, thus [tex]m = 50[/tex]

Acceleration is change in velocity divided by change in time, that is:

[tex]a = \frac{\Delta_v}{\Delta_t}[/tex]

In this problem, we don't know the velocities, but know that time is from 16s to 21s, thus:

[tex]\Delta_t = 21 - 16 = 5[/tex]

[tex]\Delta_v = v(21) - v(16)[/tex]

Thus, the force is given by:

[tex]F = ma[/tex]

[tex]F = m\frac{\Delta_v}{\Delta_t}[/tex]

[tex]F = 50\frac{[v(21) - v(16)]}{5}[/tex]

[tex]F = 10[v(21) - v(16)][/tex]
