Answer:
![\frac{9}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B4%7D%20)
Step-by-step explanation:
![\frac{2}{9} \times s = \frac{1}{2} \\ \\ \frac{2s}{9} = \frac{1}{2} \\ cross \: multiply \\ 9 \times 1 = 2s \times 2 \\ 9 = 4s \\ divivde \: both \: sides \: by \: 4 \\ \frac{9}{4} = \frac{4s}{4} \\ s = \frac{9}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B9%7D%20%20%5Ctimes%20s%20%3D%20%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5C%5C%20%20%20%5C%5C%20%20%5Cfrac%7B2s%7D%7B9%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5C%5C%20cross%20%5C%3A%20multiply%20%5C%5C%209%20%5Ctimes%201%20%3D%202s%20%5Ctimes%202%20%5C%5C%209%20%3D%204s%20%5C%5C%20divivde%20%5C%3A%20both%20%5C%3A%20sides%20%5C%3A%20by%20%5C%3A%204%20%5C%5C%20%20%5Cfrac%7B9%7D%7B4%7D%20%20%3D%20%20%5Cfrac%7B4s%7D%7B4%7D%20%20%5C%5C%20s%20%3D%20%20%5Cfrac%7B9%7D%7B4%7D%20)
hope you understand
4 (0.5f - 0.25) = 6 + f
2.0f - 1.0 = 6.0 + f
1.00f = 6.0 + f
f = -5.0
hope this is right,

Step-by-step explanation:
sin (41)×13.5
according to sin law
Answer:
A) probability that at least x of them will require repairs is less than 0.5 is 4
Step-by-step explanation:
sample size, n = 20
p = success probability of toaster = 0.2
q = failure probability of toaster =1- p = 1- 0.2 =0.8
mean, , μ = n * p = 20 * 0.2 = 4
standard deviation, ![\sigma = \sqrt{npq} = \sqrt{(20 * 0.2 *0.8)} = 1.79](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7Bnpq%7D%20%3D%20%5Csqrt%7B%2820%20%2A%200.2%20%2A0.8%29%7D%20%3D%201.79)
a) the probability that at least some of them require repairs < 0.5.
for
value of z = 0
we know ![z =\frac{x -\mu}{\sigma}](https://tex.z-dn.net/?f=z%20%20%3D%5Cfrac%7Bx%20-%5Cmu%7D%7B%5Csigma%7D)
from z table
X = 4
