Answer:

Option (3)

Step-by-step explanation:

From the picture attached,

Bar graph sketched shows the grades earned by the students in an exam.

Number of students who achieved the grade A = 17

Number of students who achieved grade B = 14

Number of students with grade C = 5

Number of students with grade D = 9

Total students who took the exam = 17 + 14 + 5 + 9 = 45

Option (1)

" $\frac{1}{5}$ of the students earned a C"

Fraction of students who earned C = $\frac{\text{Students who earned C}}{\text{Total students}}$

= $\frac{5}{45}$

= $\frac{1}{9}$

Therefore, this option is incorrect.

Option (2)

"3% more students earned an A then B"

Percentage of students who earned A = $\frac{\text{Students got A}}{\text{Total students who took the exam}}\times 100$

= $\frac{17}{45}\times 100$

= 37.78%

Percentage of students who earned B = $\frac{\text{Students got B}}{\text{Total students who took the exam}}\times 100$

= $\frac{14}{45}\times 100$

= 31.11%

Difference in percentage = 37.78 - 31.11

= 6.67%

Therefore, this option is not correct.

Option (3)

"20% of the students earned a D"

Percentage of students who earned D = $\frac{\text{Students got D}}{\text{Total students who took the exam}}\times 100$

= $\frac{9}{45}\times 100$

= 20%

Option (3) is the correct option.

Option (4)

" $\frac{1}{4}$ of the class earned a B"

Fraction of class who earned B = $\frac{\text{Students got B}}{\text{Total students who took the exam}}$

= $\frac{14}{45}$

Therefore, Option (4) is not correct.

Answer:

angles (W, X, Y) = (77°, 62°, 41°)

Step-by-step explanation:

Given:

ΔWZY

∠W = 2(∠Y) -5°

∠X = ∠Y +21°

Find:

∠X, ∠Y, ∠W

Solution:

Using angle measures in degrees, we have ...

∠X + ∠Y + ∠Z = 180

(∠Y +21) +∠Y + (2(∠Y) -5) = 180

4(∠Y) +16 = 180 . . . . . simplify

∠Y +4 = 45 . . . . . . . . . divide by 4

∠Y = 41 . . . . . . . . . . . . subtract 4

∠W = 2(41) -5 = 77

∠X = 41 +21 = 62

The angle measures of angles (W, X, Y) are (77°, 62°, 41°), respectively.
