Answer:
1) 60°, 75°, 120°, 105°
2) 101.5 m
Step-by-step explanation:
1) The sum of ratio units is 4+5+8+7 = 24, which corresponds to the sum of angles, 360°. Then each ratio unit must stand for 360°/24 = 15°. Multiplying the given ratio units by 15° gives the angle measures:
- 4×15° = 60°
- 5×15° = 75°
- 8×15° = 120°
- 7×15° = 105°

2) The similarity statement and the scale factor mean ...
MJ : TQ = 4 : 7
7·MJ = 4·TQ . . . . . . . . . "cross multiply"
TQ = 7/4×MJ = 7/4(58 m) . . . . . divide by 4, substitute the value of MJ
TQ = 101.5 m
Answer:
from left: 220, 177
Step-by-step explanation:
unit rate = first derivative = slope
first graph;
slope = (880-660)/(4-3) = 220 ft/min
2nd graph;
slope = (177-0)/(1-0) = 177 ft/min

Based on the data set shown, which of the following is a true statement? -1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
babymother [125]
<span>-1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
Median=1
</span><span>Mean=(-1+-1+0+1+1+1+1+2+2+2+3)/11=11/11=1
Mode=1
So the first option is true
Answer: mean=mode</span>
It would be 8x² - 15y² + xy
(4x + 5y) (2x - 3y) + 3xy
multiplying the terms in brackets
(4x) (2x - 3y) + (5y) (2x - 3y) + 3 xy
multiplying with each terms inside the bracket
(4x)(2x) - (4x) (3y) + (5y) (2x) - (5y) (3y) + 3xy
doing the product each of the pair of terms
8x² - 12xy + 10xy - 15y² + 3xy
taking the sum of terms with coefficient "xy"
8x² - 15y² -2xy + 3xy
8x² - 15y² + xy
