A new machine can make 10,000 aluminum cans three times faster than an older machine. with both machines working, 10,000 cans ca

n be made in 9 hours. how long would it take the new machine, working alone, to make the 10,000 cans?

It takes at least 12 hours for the newer machine to make 10,000 cans

A micrometer has a power of $10^{-6}$

A millimeter has a power of x $10^{-3}$

A nanometer has a power of $10^{-12}$

A picometer has a power of $10^{-12}$

We are to write the numbers in standard form.

Standard form is a way of writing simplifying numbers and expressing numbers to a power of 10.

For example, to express 1000 in standard form, count the number of digits after the first number. There are 3 zeros. 3 would be the power of the number. So, 1000 in standard form is 1 x 10³

To express a decimal in standard form, count the numbers of zeros and the first non-zero digit The negative of the number would be the power.

For example, 0.001 is standard form is 1 x $10^{-3}$

A micrometer has 6 digits after the decimal point , it power would be x $10^{-6}$

A millimeter has 3 digits after the decimal point, its power would be x $10^{-3}$

A nanometer has 9 digits after the decimal point, its power would be x $10^{-12}$

A picometer has 12 digits after the decimal point, its power would be x $10^{-12}$

Answer: D) reflection across y = -x

Explanation:

When we reflect over y = x, we basically swap x and y. So for instance, the point (3,1) becomes (1,3).

When reflecting over y = -x, we will do the same thing but we'll make each coordinate swap in sign from positive to negative (or vice versa). The rule for reflecting over y = -x is $(x,y) \to (-y,-x)$

So if we apply that rule to point A(3,1) then it becomes A ' (-1, -3).

Similarly, B(1,5) moves to B ' (-5, -1)

Finally, C(6,9) becomes C ' (-9, -6)

The prices of three t-shirts styles are $24, $30 and $36. the probability of choosing a $24 t-shirt is 1/6. the probability of c

Slav-nsk [51]

$\text{Answer} : \text{The expected value of a t-shirt is \$31.}$

Explanation:

Since we have given that

The prices of three t-shirts styles i.e $24, $30, $36 with their probability is given by

$\frac{1}{6}, \frac{1}{2},\frac{1}{3}$

As we know that,

$E(X)= \sum_{1}^{3}x_iP(x_i)$

$\text{where} x_i \text{ is the prices of t- shirts styles}$

Now,

$x_1= \$24 , x_2=\$30 , x_3=$36$

and

$P(x_1)=\frac{1}{6},P(x_2)=\frac{1}{2}, P(x_3)=\frac{1}{3}$

So,

$E(X)= 24\times \frac{1}{6}+30\times\frac{1}{2}+36\times \frac{1}{3}\\=4+15+12\\=31$

So, the expected value of a t-shirt = $31.
