Answer:
Step-by-step explanation:
we know that if we are given any data than total value of data=360°
Here, Total value of data =43+48+37+24 units
=152 units
152 units=360°
Hence, the measure of central angle of 43=43×(360/152)=101.84°≈102°.
measure of central angle of 48=48×(360/152)=113.68°≈113°.
measure of central angle of 37=37×(360/152)=87.63°≈88°.
measure of central angle of 24=24×(360/152)=56.84°≈57°.

Answer:
A's
Step-by-step explanation:
Mode is defined as the number, or in this case grade, that appears most often in a set of numbers. Seeing as 10 is the most number of a certain grade recieved, the corresponding grade A is the mode.
422₅ - 143₅ = 224₅
We convert each number to base 10.
So 422₅ = 4 × 5² + 2 × 5¹ + 2 × 5⁰
= 4 × 25 + 2 × 5 + 2 × 1
= 100 + 10 + 2
= 112₁₀
143₅ = 1 × 5² + 4 × 5¹ + 3 × 5⁰
= 1 × 25 + 4 × 5 + 3 × 1
= 25 + 20 + 3
= 48₁₀
So 422₅ - 143₅ = 112₁₀ - 48₁₀ = 64₁₀
We now convert 64₁₀ to base 5
64 ÷ 5 = 12 r 4,
12 ÷ 5 = 2 r 2
2 ÷ 5 = 0 r 2
Counting upwards,
So, 65₁₀ = 224₅
So, 422₅ - 143₅ = 224₅
