Out of 1,100 discs tested, 13 are defective. Estimate the number of defective discs in a batch of 41,000.

1 answer:

8 0

13/1,100 = x/ 41,000 (in English, this reads 13 out of 1,100 equals x out of 41,000) * by 41,000 and you get 41,000 x 13/1,100 = x
which is about 485

Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning.

andrey2020 [161]

Answer:

Hey! The answer is 25,4 centimeters.

Step-by-step explanation:

In a linear function you can use y=mx+n

So if x = hours and y= height.

You know that

$\left \{ {{27,8=11m +n} \atop {24,8=26m +n}} \right.$

So:

If you multiply (24,8=26m +n) x-1

It is: -24,8 = -26m -n

Adding up the other equation

-24,8 = -26m -n

27,8 = 11 x 0,2 + n

27,8 = -2,2 + n

30 = n

This results that te linear function for this equation is:

y = -0,2x + 30

The answer is

y=23(-0,2) + 30

y=-4,6+30

y=25,4

Answer:

The answer to your question is: letter B

Step-by-step explanation:

Data

A (-5, 4)

B (4, 1)

Formula

slope = m = $\frac{1 - 4}{4 + 5}$

m = $\frac{-3}{9}$ = $\frac{-1}{ 3}$

Point slope

(y - 4) = $\frac{-1}{3}$ (x + 5)

Can someone please help me its urgent!!!!!!!!!!<br> 3x + 11 = 3x - 11

user100 [1]

Answer:

$\Large\boxed{\mathsf{\Rightarrow NO\quad SOLUTIONS}}$

Step-by-step explanation:

<h3><u>TO SOLVE:</u></h3>

Isolate by the x on one side of the equation.

<h3><u>SOLUTIONS:</u></h3>

First, subtract 3x from both sides.

$\displaystyle \Rightarrow \mathsf{3x+11-3x=3x-11-3x}}$

Solve.

$\displaystyle \mathsf{11=-11}$

Sides are NOT equal.

$\Large\boxed{\mathsf{\Rightarrow THERE \quad ARE \quad NO \quad SOLUTIONS}}}$

Therefore, there are no solutions.
