Answer:
I think the answer is B <B =~ <D
Answer:
#1 is 60°, #2 is 55°
Step-by-step explanation:
all angles in a triangle add up to 180° so u can just subtract from that for the missing angles. :)
Answer:
a. What is the probability that the cost will be more than $450?
We are supposed to find P(x > 450)
Formula :
Refer the z table :
P(z<0.9431)=0.8264
P(z> 0.9431)=1-P(z<0.9431)=1- 0.8264= 0.1736
Hence the probability that the cost will be more than $450 is 0.1736
b)What is the probability that the cost will be less than $250?
We are supposed to find P(x<250)
Formula :
Refer the z table :
P(z<-1.3295)=0.0934
Hence the probability that the cost will be less than $250 is 0.0934
c)What is the probability that the cost will be between $250 and $450?
P(250<z<450)=P(z<450)-P(z<250) = 0.8264 - 0.0934 =0.733
Hence the probability that the cost will be between $250 and $450 is 0.733
d) If the cost for your car repair is in the lower 5% of automobile repair charges, what is your cost?
p = 0.05
refer the z table
z = -1.65
Formula :
Hence If the cost for your car repair is in the lower 5% of automobile repair charges, so, cost is $221.8
Answer:
B. y = -x – 1
Step-by-step explanation:
calculate slope =
y2-y1 = -5- (-2) = -3
x2-x1 = 4 - 1 = 3
m (slope) = -3/3 = -1
using points (1,-2) for calculating y-intercept:
y = mx + b
-2 = -1(1) + b
-2 = -1 + b
-1 = b
b = -1
answer is B y= -x - 1
