A scaled copy of a shape will be similar to the shape.

<em>The side length m is 4</em>

From the attached image,

All sides of ABCD are the same (i.e. 10)

Since $ABCD \sim QRST$

It means that the side lengths of QRST will also be the same

Side $QT = 4$

This means that:

$m =QT$

So, we have:

$m = 4$

Use the slope formula:

$\frac{y_2-y_1}{x_2-x_1}$

Plug in the values:

$\frac{2-(-5)}{4-0} = \frac{7}{4}$

So 7/4 is the slope.

Your first assignment at El Smello Perfume Co. is to determine the proper setting for filling the bottles. The company wishes to

SCORPION-xisa [38]

Answer:

The answer is "96.864 ml".

Step-by-step explanation:

In this question, the formula of $\bold{CI = X \pm t \times s}$ .

( where X is the mean, t is the coefficient, and s is the mean difference error)

As a result, only 2.5% of containers might include less than 100 ml of volume, its trust coefficient could indeed be used in accordance with 95%, which is $t=1.96$ .

And it can take $\pm \ 1.6 \ ml$ to have been the full value the standard infinite: $\to CI = 100 \pm (1.96 \times 1.6) \\\\$

$= 100 \pm (3.136) \\\\$

Consequently, if the standard error is $\pm \ 1.6 \ ml$ , a similar amount should be used to fill

$= 100 - 3.136 \\\\= 96.864 \ \ mL$

--2m + 4n2 for m = -6 and n=-5<br> Evaluate the expression

Tamiku [17]

Answer: 112

Step-by-step explanation:

Since we were given m and n, we plug them into the expression and solve.

-2(-6)+4(-5)² [exponent]

-2(-6)+4(25) [multiply]

12+100 [add]

112

Now, we know that the value of the expression is 112.
