First write 18% as a decimal by moving the decimal point two places to the left to get <em>.</em>18.
The word "of" means multiply, so we have (.18)(75) which is 13<em>.</em>5.
Question 1: C, x < -8 <---
Question 2: A, n>= -4
Answer:
0.45134
Step-by-step explanation:
Given that :
p = 0.6
n = 400
Probability that sample. Proportion falls between 0.59 and 0.62
Using Normal approximation :
Mean (m) = n * p = 400 * 0.6 = 240
Standard deviation (s) = sqrt(pq/n)
q = 1 - p = 1 - 0.6 = 0.4
s = sqrt((0.6 * 0.4) / 400) = 0.0244948
P(0.59 < p < 0.62) :
(x - m) / s
P((0.59 - 0.6) / 0.0244948) < p < P((0.62 - 0.6) / 0.0244948)
P(Z < −0.408249) < p < P(Z < 0.8164998)
Using the Z probability calculator :
0.79289 - 0.34155 = 0.45134
Answer:
170 cm2
Step-by-step explanation:
Area of Parallelogram = Base x Altitude
Base = 10
Altitude = 17
10 x 17 = 170
Answer = 170 cm2
Answer:
formula for gradient when given 2 points.
over here
(3-2)/(4-1) = 1/3 = -0.33333333
<h3>1/3 is the gradient</h3>
