If a copier contains 60% letter-size paper and 40% legal-size paper, what is the ratio of letter-size paper to legal-size paper?

Vladimir79 [104]

Answer:

The ratio is 3/2 or 3:2

Step-by-step explanation:

we know that

To find out the ratio of letter-size paper to legal-size paper, divide the percentage of letter-size paper by the percentage of legal-size paper

$\frac{60}{40}$

Simplify

$\frac{60}{40}=\frac{6}{4}=\frac{3}{2}$

therefore

The ratio is 3/2 or 3:2

Bess and Gina earn $45 per week for delivering flowers. Bess worked for x weeks and earned an additional total bonus of $20. Gin

Inessa05 [86]

Answer:

First option: $45x + 20 + 45y$

Step-by-step explanation:

The missing options are:

$45x + 20 + 45y\\65x + 45y\\45x - 20 + 45y\\\\45x + 65y$

We know that "x" represents the number of weeks Bess worked and "y" the number of weeks Gina worked.

According to the data given in the exercise, Gina and Bess earn $45 per week for delivering flowers, this is:

$45x+45y$

Since earned an additional total bonus of $20, then the total money in in dollars that Bess and Gina earned for delivering flowers can be shown with the following expression:

$(45x+20)+45y=45x+20+45y$

Notice that this expression matches with the one shown in the first option.

Suppose x has a distribution with μ = 40 and σ = 12. (a) If random samples of size n = 16 are selected, can we say anything abou

Temka [501]

Answer:

a: no the sample size is too small

b: Yes, the distribution is normal with a mean of 40 and standard deviation of 12

Step-by-step explanation:

a: If n < 30, we need to know that the sample is normally distributed or else we can't determine anything. When sample sized get very large, they usually resemble normally distributed data sets so we can still make conjectures even if the data isn't officially normally distributed

b: The question tells us that the sample is normally distributed, so even though n < 30, we can still make conjectures about the population
