Use cross multiplication:

$\frac{8}{12}= \frac{11}{x}\\ \\12*11=132\\8x=132\\\\x=132/8\\x=16.5$

He can get $16.5 with 12€.

Answer: The required number of dollars is 16.5 dollars.

Step-by-step explanation: Given that Tommy can exchange 8 euros for 11 dollars.

We are to find the number of dollars that Tommy get with 12 euros at this rate.

We will be using the UNITARY method to solve the given problem.

Number of dollars that Tommy get for 8 euros = 11 dollars.

So, the number of dollars that Tommy get for 1 euro will be

$\dfrac{11}{8}.$

Therefore, the number of dollars that Tommy get for 12 euros is given by

$\dfrac{11}{8}\times12=\dfrac{33}{2}=16.5.$

Thus, the required number of dollars is 16.5 dollars.

Based on historical data, your manager believes that 40% of the company's orders come from first-time customers. A random sample

Vedmedyk [2.9K]

Answer:

$P(0.26 \leq p \leq 0.43)=0.7204-0.0032=0.7172$

Step-by-step explanation:

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

The population proportion have the following distribution

$p \sim N(p=0.4,\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.4(1-0.4)}{91}}=0.0514)$

And we can solve the problem using the z score on this case given by:

$z=\frac{p_o -p}{\sqrt{\frac{p(1-p)}{n}}}$

We are interested on this probability:

$P(0.26 \leq p \leq 0.43)$

And we can use the z score formula, and we got this:

$P(\frac{0.26 -0.4}{\sqrt{\frac{0.4(1-0.4)}{91}}} \leq Z \leq \frac{0.43 -0.4}{\sqrt{\frac{0.4(1-0.4)}{91}}})$

$P(-2.726 \leq Z \leq 0.584)$

And we can find this probability like this:

$P(-2.726 \leq Z \leq 0.584)=P(Z$

Line 1 to 2: Commutative Property of Multiplication, because all that changed was the order of the things being multiplied.
Line 2 to 3: Commutative Property of *Addition*, because all that changed was the order of the things being added.

All that changed in either step was the ordering of the things being multiplied or added. That’s the commutative property.

Si mi hermano gana 589 pesos diarios si ha trabajado 15 días de este mes ¿cuánto dinero ha ganado?

weeeeeb [17]

Mi hermano ha ganado un dinero devengado de 8835 pesos en 15 días.

En esta pregunta debemos determinar el dinero devengado por un período de 15 días a partir de una tasa diaria constante. Esa cantidad es igual al producto de la tasa diaria constante, en pesos por día, y el número de días trabajados, en días:

$x = 589\,\frac{\$}{dia}\times 15\,dias$

$x = 8835\,\$$
