Answer:

30 parts

Step-by-step explanation:

We are given that machine produces 100 parts twice as  fast as machine B does.

Machine produces 100 parts in 40 minutes.

We have to find number of parts produces by machine A in 6 minutes.

According to question

Machine A  takes time to produce 100 parts =\frac{40}{2}=20 minutes

Machine A and machine B produces parts at constant rate.

Machine A produces parts at the rate=\frac{100}{20}=5 parts /minute

In one minute,Machine A produces =5 parts

In 6 minutes , machine B produces =5\times 6=30 parts

Hence, machine A produce parts in 6 minutes=30

love history [14]

Answer: 0.923

Step-by-step explanation:

Let A be the event an Internet user posts photos that they have taken themselves, and B be the event an Internet user posts videos that they have taken themselves.

Pew Research Center finds that

P(A)=0.52    P(b)=0.26,  and P(A or B)=0.54.

To find : P(A|B)

Since , \text{P(A or B)=P(A+P(B)-P(A and B)}

i.e. \text{P(A and B)=P(A)+P(B)-P(A or B)}

\text{P(A and B)=}0.52+0.26-0.54=0.24

Now, using conditional probability formula ,

P(A|B)=\dfrac{\text{P(A and B)}}{\text{P(B)}}\\\\=\dfrac{0.24}{0.26}=0.923076923077\approx0.923

Hence, the conditional probability that an Internet user posts photos that they have taken themselves, given that they post videos that they have taken themselves = 0.923

Mario compared the slope of the function graphed below to the slope of the linear function that has an x-intercept of 1 and a y-
Lelu [443]

Answer:

The slope of the function graphed is less than the linear function that has an x-intercept of 1 and a y-intercept of -2.

Step-by-step explanation:

It is given that x-intercept is 1 and y-intercept is -2.

Now, the coordinate of the point is (1,0) and (0,-2).

We know that,

Slope = \dfrac{y_2-y_1}{x_2-x_1}

S_1=\dfrac{-2-0}{0-1}

S_1 = \dfrac{-2}{-1}

S_1=2

Now, Slope of the graph given

Co-ordinate is (-5,0) and (1,2).

Using the formula of slope

S_2 = \dfrac{2-0}{1-(-1)}

S_2 = \dfrac{2}{1+1}

S_2 = \dfrac{2}{2}

S_2 =1

Now, S_1>S_2

Hence, the slope of function graphed is less than linear function that has an x-intercept of 1 and a y-intercept of -2.
