Suppose an electronics manufacturer knows from previous data that 2% of
one type of an electronic component are defective. The quality control
inspector randomly selects components until a defective one is found. Is this
a binomial experiment? Why or why not?
A. This is not a binomial experiment, because the trials are not
independent.
B. This is not a binomial experiment, because the number of trials is
not fixed.
C. This is not a binomial experiment, because each trial cannot be
classified as a success or failure.
D. This is a binomial experiment, because the situation satisfies all
four conditions for a binomial experiment.

Answer:

b=36

Step-by-step explanation:

by triangle exterior theorem

b+81 = 117

b=36

Answer:

B is 36 degrees, and a is 63 degrees

Step-by-step explanation:

180 - 117 = 63

a = 63 degrees

81 + 63 + b = 180

144 + b = 180

180 - 144 = b

36 degrees = b

Answer:

E and D

Step-by-step explanation:

The area of a rectangle is length x width. In this case, that's (12+s) x 1/3

This can be re-written as 1/3(12+s)

D is 1/3s + 4 which is what happens when you multiply 1/3 by 12 which = 4 and multiply 1/3 by s which = 1/3s. So the answer is 1/3s+4.

Answer:

2880 square units

Step-by-step explanation:

Since the area of a rhombus, A = d₁ × d₂/2 where d₁ and d₂ are its diagonals. Given that d₁:d₂ = 2:1, d₁/d₂ = 2/1, so d₁ = 2d₂. Also, the length of side of the rhombus L = 60 units.

We find the length of the diagonal by Pythagoras' theorem since the diagonals are perpendicular to each other and bisect each other at their mid point.

The mid point of d₁ = d₁/2 and the midpoint of d₂ = d₂/2.

By Pythagoras' theorem,

L² = (d₁/2)² + (d₂/2)²

L² = d₁²/4 + d₂²/4

Now, d₁ = 2d₂

So, L² = (2d₂)²/4 + d₂²/4

L² = 4d₂²/4 + d₂²/4

L² = d₂² + d₂²/4

L² = 5d₂²/4

d₂² = 4L²/5

taking square root of both sides,

√d₂² = √(4L²/5)

d₂ = 2L/√5

Since L = 60 units, then

d₂ = 2L/√5

d₂ = 2(60)/√5

d₂ = 120/√5

rationalizing the denominator by multiplying the numerator and denominator by √5, we have

d₂ = 120/√5 × √5/√5

d₂ = 120√5/5

d₂ = 24√5 units

So, our area A = d₁ × d₂/2

Since d₁ = 2d₂, our area is

A = 2d₂ × d₂/2

A = d₂ × d₂

A = d₂²

substituting d₂ = 24√5, we have

A = d₂²

A = (24√5)²

A = (24)²(√5)²

A = 576 × 5

A = 2880 square units

Answer:

Step-by-step explanation:

r=6.7

Given:

The function is

[tex]f(x)=2x^3+ax^2-37x-60[/tex]

The binomial [tex]x-4[/tex] is a factor of f(x).

To find:

The value of [tex]a[/tex].

Solution:

If [tex]x-c[/tex] is a factor of f(x), then [tex]f(c)=0[/tex].

It is given that, [tex]x-4[/tex] is a factor of f(x), then [tex]f(4)=0[/tex].

We have,

[tex]f(x)=2x^3+ax^2-37x-60[/tex]

Substituting x=4, we get

[tex]f(4)=2(4)^3+a(4)^2-37(4)-60[/tex]

[tex]f(4)=2(64)+a(16)-148-60[/tex]

[tex]f(4)=128+16a-208[/tex]

[tex]f(4)=16a-80[/tex]

Now,

[tex]f(4)=0[/tex]

[tex]16a-80=0[/tex]

[tex]16a=80[/tex]

[tex]a=\dfrac{80}{16}[/tex]

[tex]a=5[/tex]

Therefore, the value of a is 5.

Answer:

∠J = 107°

∠K =107°

∠L = 73°

∠M = 73°

Step-by-step explanation:

Angle J + angle M = 180°

(10x - 33) + (4x+17) = 180

simplify:

14x -16 = 180

14x = 196

x = 14

∠J = 10(14) - 33 = 107°

∠M = 4(14) + 17 = 73°

Answer:

See explanation.

Step-by-step explanation:

If the odd number is 2n+1 note that n can be any number because any even number plus one will be odd. Let's start by squaring 2n+1 to get:

[tex]4n^2+4n+1[/tex]

Consider xy (x times y). xy is a multiple of both x and y because xy/x = y and xy/y = x. So it doesn't matter what n is it will be a multiple of 4. So now we know that 4n^2 and 4n are both multiples of 4. If we add them together, it will still be a multiple of 4. 2x + 4x = 6x and 6x is still divisible by x.

Now the plus 1 will always make it so it will be one more than a multiple of 4.

He keeps = 150

ANd, he gives her = 100

Answer and Step-by-step explanation:

A pair of segments that are perpendicular to each other are the line segments:

KI (the letter i) and MJ.

This is because we see that at the intersection T, there a right angle symbol, which means that those 4 angles at the intersection are 90 degrees. When a line meets another line, and it is perpendicular to that line, they form 90 degrees.

So, those line segments are perpendicular.

Answer:

  A = 500

  B = 1.04

  49.6 years

Step-by-step explanation:

We assume your 'A' and 'B' refer to parameters in an exponential formula of the form ...

  y = A·B^x

In this form, A is the initial investment value, $500. B is the growth factor, 1+4% = 1.04, assuming interest is compounded annually. We want to find x such that y=$3500.

  3500 = 500·1.04^x . . . . . fill in known values

  7 = 1.04^x . . . . . . . . . . . . . divide by 500

  log(7) = x·log(1.04) . . . . . . take logarithms

  x = log(7)/log(1.04) ≈ 49.61 . . . . divide by the coefficient of x

It will take about 49.6 years for there to be $3500 in Mrs. Williams's account.
