little bit confused about this question

Answer:

65 degrees

Step-by-step explanation:

Since the two straight lines are parallel, this means that Angle 1 and the 65 degrees angle are alternate interior angles; meaning that they're congruent.

So:

Angle 1 = 65 degrees

Hope this helps!

Please let me know if I'm incorrect :)

Answer:

The answer is 65  (degree symbol here)

Step-by-step explanation:

two interior angles on the inside of this shape will always be the same

Step-by-step explanation:

Consider the problem

Let, E 1 and E 2

​  be the respective events of items produced by machine A and B.

And let x be the event that the produced item was found to be defective.

Therefore,

Probability of items produced by machine A,P (E 1)=60%= 53

Probability of items produced by machine B,P (E 2)=40%= 52

And,

Probability that machine A produced defective items, P( E 1 x)=2%= 1002

Probability that machine B produced defective items, P( E 2 x)=1%= 1001

So, the probability that randomly selected items was from machine A is given by P( x E 1)

Now, Apply Bayes' Theorem

P( x E 1)= P(E 1)P( E 1x )+P(E 2)P( E 2x)P(E 1)P( E 1x)= 52× 1001 + 5

3× 1002

53× 100

2= 2+5

6= 11

6

Hence, the required probability of machine A is  

11

6

​

The required answers are,

A.) The probability that the unit is defective is 0.046

B.) The probability that it was manufactured by machine M2​ is 0.4

Probability is the extent to which an event is likely to occur, measured by the ratio of the favorable cases to the whole number of cases.

Now given that,

Product produced by machine M1 = 60%

⇒ P(M1) = 60% = 0.6

Defective units = 5%

⇒ P(D1) = 5% = 0.05

Product produced by machine M2 = 40%

⇒ P(M2) = 40% = 0.4

Defective units = 4%

⇒ P(D2) = 4% = 0.04

Now, a unit is selected at random from the whole product

So, probability that it is defective is given as,

P(D) = P(D|M1) * P(D1) + P(D|M2) * P(D2)

⇒ P(M1|M2) = (0.6 X 0.05) + (0.4 X 0.04)

⇒ P(M1|M2) = 0.03 + 0.016

⇒ P(M1|M2) = 0.046

And probability that it was produced on the first machine(M2).

P(M2|D1) = P(M2∩D1) / P(D1)

⇒ P(M2|D) = (0.4 X 0.04)/0.04

⇒ P(M2|D) = 0.016 / 0.04

⇒ P(M2|D) = 0.4

Thus, the required answers are,

A.) The probability that the unit is defective is 0.046

B.) The probability that it was manufactured by machine M2​ is 0.4

Answer:

  2)  (-∞, 17]

Step-by-step explanation:

The leading coefficient of the function is negative, so the parabola opens downward. The vertex will be a maximum, the upper end of the range. The lower end of the range will be -∞.

The vertex of the function lies on the axis of symmetry. The maximum can be found by evaluating the function at x=-4.

  y = -(-4)² -8(-4) +1 = -16 +32 +1 = 17

The range of the function is (-∞, 17].

Answer: upper bound = 89.36 and lower bound = 94.64

Step-by-step explanation:

Confidence interval for mean : [tex]\overline{x}\pm z^*\dfrac{\sigma}{\sqrt{n}}[/tex], where [tex]\overline{x}[/tex] = sample mean , n= sample size , z* = two-tailed critical value, [tex]\sigma[/tex]= population standard deviation

As per given , we have

[tex]\overline{x}[/tex] = 92

n =  55

[tex]\sigma[/tex]= 10

Critical value for 95% confidence interval = 1.96

Required confidence interval :  [tex]92\pm (1.96)\dfrac{10}{\sqrt{55}}[/tex]

[tex]92\pm (1.96)(1.3484)\approx92\pm2.64\\\\= (92-2.64,\ 92+2.64)\\\\=(89.36,\ 94.64)[/tex]

Using the normal distribution, it is found that there is a 0.6406 = 64.06% probability that the company will have to refund money to a customer.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Researching the problem on the internet, it is found that the mean and the standard deviation are, respectively, given by [tex]\mu = 13[/tex] and [tex]\sigma = 2.75[/tex].

The probability it lasts less than 14 years is the p-value of Z when X = 14, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{14 - 13}{2.75}[/tex]

[tex]Z = 0.36[/tex]

[tex]Z = 0.36[/tex] has a p-value of 0.6406.

0.6406 = 64.06% probability that the company will have to refund money to a customer.

1, 3, 9, 27, 81

Step-by-step explanation:

A remainder of 2 indicated that the multiplication of any factors will be two less than 83.

Step 1: 83-2=81

Step 2: Find all factors of 81

1, 3, 9, 27, 81

All the different natural numbers are;

⇒ 3, 6, 9, 81

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

All the different natural numbers that each leave a remainder of 2 when divided into 83.

Since, The remainder is 2

So, The value of number = 83 - 2

                                       = 81

Now, All the factors of 81 are,

⇒ 3, 6, 9, 81

Thus, All the natural number which divides the 83 and leave the remainder 2 are,

⇒ 3, 6, 9, 81

Answer:

Step-by-step explanation:

1. 18-3=15

2. 1+2=3

3. 15÷3=5

Always remember to bear in mind your mathematic vocabulary.

Polynomial functions' standard form is f(x)=ax^n+bx^n-1...+k

However, polynomials can also be written in intercept form

f(x)=(x-x1)(x-x2)(x-x3)...(x-xn) for roots/zeros x1,x2,x3,...,xn

With the three numbers that you have -2, 3, -4 you can write function

f(x)=(x-(-2))(x-3)(x-(-4))

Then you can simplify and distribute

f(x)=(x+2)(x-3)(x+4)

f(x)=(x^2-x-6)(x+4)

f(x)=x^3+3x^2-10x-24

Which would be the answer
