A bakery sold 36 brownies in a day, which was 30% of the total items sold that day. What was the total number of items the baker
babymother [125]

Answer:

120

Step-by-step explanation:

We know that 36 is 30% of total items

So our equation would be 36/? = 30/100

From there we cross multiply so 36x100 = 3600

From there, we divide 3600 by 100

Therefore, your answer is 120

WILL NAME BRAINLIEST-PLEASE DONT ANSWER IF YOU DONT KNOW
mojhsa [17]

Answer:

Infinite Solutions

Step-by-step explanation:

x + 2y = 10

6y = 3x - 30

To solve for x and y we use substitution method

Let's solve the first equation for x

x + 2y = 10

Subtract 2y on both sides

x = 10 - 2y

Now plug in x in second equation

6y = -3x + -30

6y = -3 (10-2y) - 30

6y = -30 + 6y - 30

6y = 6y

Both sides are the same, so both x and y have infinite solutions.

The brain volumes ​(cm cubed​) of 20 brains have a mean of 1162.8 cm cubed and a standard deviation of 127.1 cm cubed. Use the g
Free_Kalibri [48]

Answer:

- The limits are  908.6 cm^3 and 1417cm^3

- 1337.0cm^3 is in between the limits

Step-by-step explanation:

To determine the limit by taking into account the range rule of thumb, you use the fact that the limits are given by the mean plus and minus twice the standard deviation, that is:

\overline{x}\pm 2\sigma        (1)

\overline{x}: mean of brain volume = 1162.8 cm^3

σ: standard deviation = 127.1 cm^3

You replace the values of the parameters in the equation (1):

1162.8cm^3+2(127.1cm^3)=1417cm^3\\\\1162.8cm^3-2(127.1cm^3)=908.6cm^3

Limits = (1417 , 908.6)

The limits are  908.6 cm^3 and 1417cm^3

1337.0cm^3 is in between the limits calculated above.
