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.

Mary's math certificate is 10 inches tall and 13 inches wide. Mary wants to put the certificate

wlad13 [49]

Answer:

$219.70

Step-by-step explanation:

First, you need to find the area of the certificate, which you can do by multiplying 10*13, since it is a rectangle. 10*13 is 130. Then, multiply 130 by the price per inch, which is $1.69. 130*1.69=219.7, which in financial terms would amount to $219.70.

In a circle with an 8-inch radius, a central angle has a measure of 60°. How long is the segment joining the endpoints of the ar

g100num [7]

Given the radius, circumference can be solved by the equation, C = 2πr. The circumference of the circle above is C = 2π(8 in) = 16<span>π in. To solve for the length of the segment joining the arc is the circumference times the ratio of central angle and 360 degrees.

Length of the segment = (16</span>π in)(60/360) = 8/3 <span>π in

Thus, the length of the segment is approximately 8.36 in. </span>
