Answer:

1.4 cupcakes can a baker decorates in 1 minutes.

Step-by-step explanation:

A baker decorates in 30 minutes = 42 cupcakes

If she decorates at a constant rate.

To find out how many cupcakes can the baker decorate per minute, we divide 42 by 30

she decorate in 1 minute = \frac{42}{30}

= 1.4 cupcakes

1.4 cupcakes can a baker decorates in 1 minutes.

45 + 57 = x + y<br> x= 37<br> y =?
Mekhanik [1.2K]

Answer:

y = 65

Step-by-step explanation:

45 + 57 = x + y

x = 37

45 + 57 = 37 + y

45 + 57 = 102

102 = 37 + y

102 = 37 + y

-37    -37

102 - 37 = 65

37 + y - 37 = y

65 = y

y = 65

Which of the following represents the equation of a line that is parallel to 2y-x=16 and passes through the
Sliva [168]
The correct equation would be Y=1/2x+4 :)

This is true because both equations have the same slope therefore they are parallel and the equation above also includes point (-6,1).

Given the first type of plot indicated in each pair, which of the second plots could not always be generated from it?
Kisachek [45]

Answer:

d. box plot, stem and leaf

Step-by-step explanation:

The box plot depicts the five number summary minimum, 1st quartile, median, third quartile and maximum while stem and leaf plot shows every observation in data. So, when the box plot is given, we can't generate stem and leaf plot for the data because we don't have sufficient information in this scenario i.e., we don't have every data value to generate stem and leaf plot. Whereas, If the stem and leaf plot is given first then we can generate box plot from it because we have every data value to compute 5-number summary to generate box plot.

a. From dot plot, the histogram can be generated because dot plot represents every data value in the form of dots and from every data value, we can generate histogram.

b. From dot plot, the stem and leaf plot can be generated because dot plot represents every data value in the form of dots and from every data value, we can generate stem and leaf plot.

c. From stem and leaf plot, the dot plot can be generated because stem plot represents every data value in the form of stem and leaf i.e. 12 can be represented as 1 for a stem and 2 for a leaf (1  2)  and so, from every data value we can generate dot plot.

d. From box plot, the stem and leaf plot can't be generated and the reason is explained in first paragraph. So, when the first type of plot is box plot then from it second plot stem and leaf plot can't be generated.
