Answer:
e =180-92=88
value of c =value of c(vertically opposite angles)
value of c and d is 92 and 88 therefore third angle=180-(92+88)
=180-180=0
Answer: =1.34
Step-by-step explanation:
In standard density curve
P(Z<z) = Area left of z, P(Z>z) = area right of z.
P(Z<z) +P(Z>z) =1
Given: z is a standard normal random variable.
To find : value of z if rea to the right of z is 0.01.
i.e. P(Z>z) =0.01
P(Z<z) =1-0.01 = 0.09
from z-score table, z value for this is 1.34.
Hence, z= 1.34
Answer:
y = 16
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 48 when x = 6, thus
k = = = 8
y = 8x ← equation of variation
When x = 2, then
y = 8 × 2 = 16
An easy way is to multiply 9 by factors of 10
10
100
1000
9 times 10=90
9 times 100=900
9 times 1000=9000
and so on
or you could find multipules of 9 that are over 27
multipulse are
9,18,27,36,45,54,63,72,81,90,99,108,117,126,135,144,153,162,171,180,189,198,207,216, etc
so basically you could use any number in that list from 27 and after
The area of the triangle is (1/2)(DE)^2*tan(60°) = (1/2)*2*√3 = √3.
Selection C is appropriate.
