1b) 70, 40
1c) 45, 90
1d) 25%
1e) 5%
2a) 360
2b) 180
2c) protractor
2d) compass
2e) diameter
2f) radius
2g) 90
2h) acute
For 1b), the other equal angle would be 70; the remaining angle would be 180-(70+70) = 180-140 = 40.
For 1c), the other equal angle would be 45; the remaining angle would be 180-(45+45) = 180-90 = 90.
For 1d), he saved 50/200; dividing this, we get 0.25; 0.25*100 = 25%.
For 1e), he saved 28/560; dividing this, we get 0.05; 0.05*100 = 5%.
Answer:
Normal distribution
Step-by-step explanation:
The answer is "normal distribution". This is because in a normal distribution, the mean, median and mode are equal. What this means is that the distribution will be symmetrical with a bell curve unlike in positive or negative skew where it is skewed to either the left or right.
1 should be b and 2 should be a
The total bill for the Cunningham family was $29.26.
Step-by-step explanation:
Step 1; First we total up the cost of the food alone. Mr. Cunningham spent $7.50, Mrs. Cunningham spent $6.25, the 2 children spent $4.99 each which equals $9.98 for both. So the total of the food alone was $23.73.
Step 2; The sales tax rate was 7.25% of the $23.73. So we multiply 0.0725 (7.25%) with the $23.73 which equals $1.72. So the total bill was for $23.73 + $1.72 which equals $25.45.
Step 3; The Cunningham family left a 15% tip. This was 15% of the toal bill which was $25.45. So we multiply 0.15 (15%) with $25.45 which equals $3.81. So the total bill was food cost + service tax + tips which is $23.73 + $1.72 + $3.81 = $29.26
In A Circle:
If AB || CD ⇒ BC = AD = 16°
AB + BC + CD + AD = 360°
AB + CD + 2BC = 360°
48° + CD + (2*16°) = 360°
CD = 360° - 48° - 32°
CD = 280°
