It takes Mario and Jessica 15 minutes to set up 5 tables. If Mario and Jessica work at a constant rate, which best describes a p

AfilCa [17]

Answer:

3 minutes per table

Step-by-step explanation:

15 minutes = 5 tables

to get how much it will be per table, divided both sides by 5

since 5 / x = 1 and x would be 5

15 / 5 minutes = 5 / 5 tables

3 minutes = 1 table

Graph the line with slope 1/4 and y-intercept -8

kherson [118]

Solution: Below! ^^

Detailed explanation:

Hii! I'm sorry, I can't graph the line for you, but I'll try to give you the best possible explanation.

First, note that the question provides us with the info that the y intercept is -8. This is a very valuable piece of information!

This means that the line crosses the y axis (since it's the y intercept) at the point (0,-8). Plot it on the co-ordinate plane.

Next, this question also provides us with the fact that the slope of the line is 1/4. This is yet another valuable piece of information!

What this tells us is: from that point (0,-8), you need to go up 1 unit, then over 4, and so forth, until you obtain a line.

The following are the last 7 days adjusted closing stock prices (in $) for Citigroup: 22, 25, 20, 15, 40, 55, 28 A) Compute the

son4ous [18]

Answer:

(A) The 25th percentile is 20.

(B) The mean of the data set is 20 and the median of the data set is 25. The data set is left-skewed.

Step-by-step explanation:

The data set arranged in ascending order is:

S = {15, 20, 22, 25, 28, 40, 55}

(A)

Compute the 25th percentile as follows:

$25^{th} \text{Percentile}=[\frac{n+1}{4}]^{th}obs.\\\\=[\frac{7+1}{4}]^{th}obs.\\\\=2^{nd}obs.\\\\=20$

Thus, the 25th percentile is 20. This value implies that exactly 25% of the observations are less than 20.

(B)

Compute the sample mean as follows:

$\text{Mean}=\frac{22+25+20+15+40+55+28}{7}=\frac{205}{7}=29.29$

Compute the median as follows:

For a set with odd number of observations, the median value if the middle value.

The middle value is 25.

Thus, the mean of the data set is 20 and the median of the data set is 25.

The Mean < Median.

This implies that the data set is left-skewed.

Drag a figure into each blank space so that the two figures in the row match the description.

LekaFEV [45]

Answer:

i) not similar but corresponding angles have equal measures.

the blue object required to be dragged to the box is the fourth object which is a square. A square will not have proportional lengths and is not similar to the given figure but the corresponding angles will have equal measures.

ii) not similar but side lengths are proportional.

the blue object required to be dragged to the box is the first object which is a parallelogram. A parallelogram will have proportional lengths and is not similar to the given figure because the corresponding angles do not have equal measures.

Step-by-step explanation:

i) not similar but corresponding angles have equal measures.

the blue object required to be dragged to the box is the fourth object which is a square. A square will not have proportional lengths and is not similar to the given figure but the corresponding angles will have equal measures.
