Answer:
The number of cubes that fill the prism is 24
Step-by-step explanation:
Given as :
The length of cube (l) = cm
The length of prism (L) = 1 cm
The width of prism (w) = 2 =
cm
The height of prism (h) = cm
Let the number of cubes that fill the prism = x
Now, Volume of cube with length (l) = l³ cm³
Or, Volume of cube with length (l) = cm³
Or, Volume of cube with length (l) = cm³
Again , Volume of prism =
Or, Volume of prism =
Or, Volume of prism = cm³
<u>So , The number of cubes to fill prism </u>
The number of cubes × Volume of cube = Volume of prism
Or, x × cm³ =
cm³
or x = = 24
Hence The number of cubes which fill the prism is 24 Answer
Answer:
The probability that the sample proportion will be greater than 13% is 0.99693.
Step-by-step explanation:
We are given that a large shipment of laser printers contained 18% defectives. A sample of size 340 is selected.
Let = <u><em>the sample proportion of defectives</em></u>.
The z-score probability distribution for the sample proportion is given by;
Z = ~ N(0,1)
where, p = population proportion of defective laser printers = 18%
n = sample size = 340
Now, the probability that the sample proportion will be greater than 13% is given by = P( > 0.13)
P( > 0.13) = P(
>
) = P(Z > -2.74) = P(Z < 2.74)
= <u>0.99693</u>
The above probability is calculated by looking at the value of x = 2.74 in the table which has an area of 0.99693.
