One of u guys helped me but they keep returning it saying show your work>:(​
Rom4ik [11]

Answer:  She will need 36 yards of material.

Step-by-step explanation:

16 × 2¹/₄ can be done different ways,

First multiply ¹/₄ times 16. that is the same as dividing 16/4 = 4

Then multiply 2 times 16  2×16 = 32

Add 32 + 4 = 36

Another way is to change 2¹/₄ to an improper fraction and multiply

⁹/₄ × 16

   16

  <u> ×9</u>

   54  

<u> +9   </u>

 144

 

144/4 = 36

Please explain how you got your answer!!! The dot plots below show the ages of students belonging to two groups of salsa classes
Rudik [331]

Answer:

Group b most likely has a lower mean age of salsa students

Step-by-step explanation:

Arithmetic Mean of the data is the average of a set of numerical values, calculated by adding them together and dividing by the number of terms in the set.

Here we are given with two groups that are Group A and Group B

both having total number of students = 20

Here the mean age of the data is addition of the all ages of different students divided by total number of students.

For group a

total age of the group = 3 × 5 + 4 × 10 + 6 × 17 + 4 × 24 + 3 × 29

= 15 + 40 + 102 + 96 + 87

=340

The mean age of salsa students= 340 ÷ 20 = 17

For group b

total age of the group = 6 × 7 + 3 × 10 + 4 × 14 + 5 × 16 + 2 × 21

= 42 + 30 + 56 + 80 + 42

=250

The mean age of salsa students= 250 ÷ 20 = 12.5

So the group b most likely has a lower mean age of salsa students

( HELP ASAP! EASY POINTS ) The picture below shows a box sliding down a ramp:
TEA [102]

Answer:

AC = 14 cosec(68)

Explanation:

Here given:

  • angle: 68°
  • opposite: 14 ft
  • hypotenuse: AC

Use sine rule:

\rightarrow \sf sin(x) = \dfrac{opposite}{hypotenuse}

\rightarrow \sf sin(68) = \dfrac{14}{AC}

\rightarrow \sf AC= \dfrac{14}{ sin(68) }

\rightarrow \sf AC= 14  \ cosec(68)
