Answer:

the height is 14

Step-by-step explanation:

since the volume in a rect. prism is V = width x height x length, and the width times length is the area of the base, for height we need to do 840/60 to find the height

840/60 = 14

Drake rolls two fair number cubes.

Margaret [11]

Answer:

23/36

Step-by-step explanation:

In the figure attached, the possible outcomes are shown. We can see that there are 6*6 = 36 total outcomes, 23 of them are less than 14. Then the probability that the product of the two numbers Drake rolls is less than 14 is 23/36

When a truckload of apples arrives at a packing plant, a random sample of 150 is selected and examined for bruises, discoloratio

myrzilka [38]

Answer:

c. 0.088

Step-by-step explanation:

Let p(s) be the proportion of apples defected in the sample. The probability that p(s)<0.05 can be calculated by calculating z statistic of 0.05:

$\frac{p(s)-p}{\sqrt{\frac{p*(1-p)}{N} } }$ where

p(s) = 0.05

p is the proportion of the apples in fact defected (0.08)

N is the sample size (150) Then,

z(0.05)= $\frac{0.05-0.08}{\sqrt{\frac{0.08*0.92)}{150} } }=-1.354$

And P(z<-1.354)≈0.0879

Therefore the probability that a random sample of 150 among 8% defected apples can be accepted is 0.088.

When you round a number, what should you do with

shusha [124]

Answer:

In general, to round to a certain place value, look at the digit to the right of that place value and make a decision. Example: 5.1837 to the nearest hundredth would be 5.18 (round down since 3<5 ), but to the nearest thousandth, it is 5.184 (round up because 7≥5 ).

Find the arc length of the semicircle. Either enter an exact answer in terms of π or use 3.14 for π and enter your answer as a d

juin [17]

Answer:

9.42

Step-by-step explanation:

The circumference of a circle is calculated using the following formula:

C=2πr (C: circumference, r : radius)

radius here is 6 and π is given as 3.14

2*(3.14)*6 = 18.84 now divide this by 2 to find the length of semicircle

18.84/2 = 9.42
