Answer:
if you are asking (2m - 10m + 5) + (8m +2), the answer would end up just being 7.
Step-by-step explanation:
simplify, 2m-10m = -8m.
5 + 2 = 7
-8m + 8m = (they cross each other out. you can't have a 0m)
Your Answer = 7
The answer is
x^3+4x^2-8x+3
The measure of arc AC is 40°
Step-by-step explanation:
In any circle the measure of an inscribed angle is one-half the measure of its subtended arc
In circle O
∵ ∠BAC is an inscribed angle subtended by arc BC
∴ m∠BAC = m arc BC
∵ m∠BAC = 70°
- Substitute it in the the expression above
∴ 70 = m arc BC
- Multiply both sides by 2
∴ 140 = m arc BC
∴ The measure of arc BC is 140°
∵ AB is a diameter
- The diameter divides the circle into two equal arcs
∴ m of arc ACB = measure of the circle
- The measure of the circle is 360°
∴ m of arc ACB = (360°)
∴ m of arc ACB = 180°
∵ m arc BC + m arc AC = m arc ACB
∴ 140° + m arc AC = 180°
- Subtract 140 from both sides
∴ m arc AC = 40°
The measure of arc AC is 40°
P(x<4600) will be obtained as follows:
z-score is given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
plugging the values in the equation we get:
z=(4600-4500)/110
z=0.91
thus
P(x<4600)=P(z<0.91)=0.8186
