Answer:

3 3/4 tablespoons of coffee to make 10 cups of coffee

3 3/4 =15/4

10 cups require 15/4 tablespoon of coffee

1 cup require how much

15/4 divide by 10

15/4 ÷ 10

=15/4 * 1/10

=15/40

=3/8 tablespoon of coffee for 1 cup of coffee

Answer:

3/8 Tablespoon per cup

Step-by-step explanation:

Our unit rate here is

3 3/4 Tablespoons

-----------------------------

10 cups coffee

Converting 3 3/4 to an improper fraction, we get 15/4 Tablespoons:

15/4 Tablespoons 15

--------------------------- = -------- Tablespoons/cup

10 cups coffee 40

Reduce this by dividing numerator and denominator both by 5:

3/8 Tablespoon per cup

Molly needs to classify the triangle below based on angles. Which class is correct? 60° 50° 70° A. acute triangle О B. isosceles

Art [367]

Answer:

A. Actute triangle

Step-by-step explanation:

Is A because an acute triangle is a triangle where all the angles are the same.

Can not be B. because isosceles triangles have two sides that are the same which doesn't relate to angles.

Can not be C. because equilatiral triangles are triangles with sides that are all the same.

Can not be D. because for a triangle to be obtuse one of the angles needs to be greater that 90 degrees.

So it has to be A.

If the ceos salary of 1,000,000 is taken out of the list what I would happen to the mean and median 25,25,25,35,35,45,45,55,55

Mama L [17]

Answer:

Both the mean and median decrease.

Step-by-step explanation:

Median (without 1,000,000):

25, 25, 25, 35, 35, 45, 45, 55, 55

= 35

Median (with 1,000,000):

25, 25, 25, 35, 35, 45, 45, 55, 55, 1,000,000

= average of 35 and 45

= 40

As you can see, without the outlier, the value of the median decreases.

Mean (without 1,000,000):

= (25 + 25 + 25 + 35 + 35 + 45 + 45 + 55 + 55) / 9

= 38.3

Mean (with 1,000,000):

= (25 + 25 + 25 + 35 + 35 + 45 + 45 + 55 + 55 + 1,000,000) / 10

= 100,0034.5

As you can see, without the outlier, the value of the mean dramatically decreases.
