what is the answer of this 100 x 20 =

Look where the graph crosses the vertical y axis. This point is the y intercept.

In this case, the y intercept is located at (0, -1)

You start at the origin (0,0) and move down 1 unit to get to (0, -1)

Side note: The equation of this line is y = 2x-1

Answer:

a

 Mutually exclusive

b

Not Mutually exclusive

c

Not Mutually exclusive

d

Not Mutually exclusive

Step-by-step explanation:

From the question we are told that

The number of bolt is n = 12

The event that all the bolt are torqued correctly is A

The event that the 3rd bolt is not torqued correctly is B

The event that exactly one bolt is not torqued correctly is C

The event that the [tex]4^{th}[/tex] and [tex]8^{th}[/tex] are torqued correctly is D

Generally for an event to be mutually  exclusive it means that both event can not occur at the same time

    Considering a  

      The  A and  B are mutually exclusive because they can not occur at the same time

    Considering b  

 The  event B and D are not mutually exclusive because they can occur at the same time

    Considering c

 Event  C and  D are not mutually exclusive because they can occur at the same time

    Considering d

   Event       B and  C are not mutually exclusive because they can occur at the same time

The value of the function f(x) at x = - 2 is equivalent to 32.

Given is that the average rate of change of the function f(x) on the interval -2 is less than or equal to [x] which is less than or equal to 4 is -3.5.

In the range of {- 2 ≤ x ≤ 4}, the rate of change of f(x) is -3.5. This means we can write -

r = {f(4) - f(-2)}/(4 + 2)

f(4) = 11 and [r] = - 3.5. So, we can write -

- 3.5 = {11 - f(-2)}/6

11 - f(-2) = -3.5 x 6

11 - f(-2) = - 21

f(-2) = 11 + 21

f(-2) = 32

Therefore, the value of the function f(x) at x = - 2 is equivalent to 32.

Answer:

I would say 15 ounces

Answer:

55

Step-by-step explanation:

This is the equation of a parabola. To make things simpler, we can replace [tex]h[/tex] with [tex]y[/tex] and [tex]t[/tex] with [tex]x[/tex]. Therefore, [tex]y=-5x^2+30x+10[/tex]. Because the coefficient of the [tex]x^2[/tex] term is negative, we know the parabola points down, and the maximum height is the vertex. The x coordinate of the vertex of a parabola can be found with the equation [tex]-\frac{b}{2a}[/tex], or [tex]-\frac{30}{-10} = 3[/tex]. Plugging in [tex]3[/tex] into the equation gives us [tex]y = -5(3)^2+30(3)+10 = \boxed{55}[/tex]

Answer:

230

Step-by-step explanation:

You should multiply 345 by 2/3 or you can divide 345 by 3, which equaks 115 and then multiply 115 by 2 which equals 230.

The number of boys in the school is 207.

Given

The ratio of girls to boys in a school simplifies to 2:3.

We need to find out how many boys are there if there are 345 students in the school.

The ratio gives us an idea between two quantities.

It is denoted by a:b

Example:

The ratio of apple and mango in the basket is 1:2.

The total number of fruits is 12.

Apple = [ 1 / (1+2) ] x 12 = (1/3) x 12 = 4

Mango = [ 2/(1+2) ] x 12 = (2/3) x 12 = 2 x 4 = 8

We have,

Total number of students = 345

The ratio of girls to boys = 2:3

The number of boys :

= [ 3 / (2+3) ] x 345

= [ 3/5 ] x 345

= 3 x 69

= 207

Thus the number of boys in the. school is 207.

Answer:

There is approximately 17% chance of a person not having a disease if he or she has tested positive.

Step-by-step explanation:

Denote the events as follows:

D = a person has contracted the disease.

+ = a person tests positive

- = a person tests negative

The information provided is:

[tex]P(D^{c})=0.95\\P(+|D) = 0.98\\P(+|D^{c})=0.01[/tex]

Compute the missing probabilities as follows:

[tex]P(D) = 1- P(D^{c})=1-0.95=0.05\\\\P(-|D)=1-P(+|D)=1-0.98=0.02\\\\P(-|D^{c})=1-P(+|D^{c})=1-0.01=0.99[/tex]

The Bayes' theorem states that the conditional probability of an event, say A provided that another event B has already occurred is:

[tex]P(A|B)=\frac{P(B|A)P(A)}{P(B|A)P(A)+P(B|A^{c})P(A^{c})}[/tex]

Compute the probability that a random selected person does not have the infection if he or she has tested positive as follows:

[tex]P(D^{c}|+)=\frac{P(+|D^{c})P(D^{c})}{P(+|D^{c})P(D^{c})+P(+|D)P(D)}[/tex]

              [tex]=\frac{(0.01\times 0.95)}{(0.01\times 0.95)+(0.98\times 0.05)}\\\\=\frac{0.0095}{0.0095+0.0475}\\\\=0.1666667\\\\\approx 0.1667[/tex]

So, there is approximately 17% chance of a person not having a disease if he or she has tested positive.

As the false negative rate of the test is 1%, this probability is not unusual considering the huge number of test done.

Step-by-step explanation:Simplifying

3t + -5 = 0

Reorder the terms:

-5 + 3t = 0

Solving

-5 + 3t = 0

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '5' to each side of the equation.

-5 + 5 + 3t = 0 + 5

Combine like terms: -5 + 5 = 0

0 + 3t = 0 + 5

3t = 0 + 5

Combine like terms: 0 + 5 = 5

3t = 5

Divide each side by '3'.

t = 1.666666667

Simplifying

t = 1.666666667

Answer:

t = 5/3

t = 1 2/3

Step-by-step explanation:

Hi !

3t - 5 = 0

3t = 0 + 5

3t = 5

t = 5/3

t = 1 2/3
