Step-by-step explanation:
Given that the graph shows the normal distribution of the length of similar components produced by a company with a mean of 5 centimeters and a standard deviation of 0.02 centimeters.
A component is chosen at random, the probability that the length of this component is between 4.98 centimeters and 5.02
=P(|z|<1) (since 1 std dev on either side of the mean)
=2(0.3418)
=0.6826
=68.26%
The probability that the length of this component is between 5.02 centimeters and 5.04 centimeters is
=P(1<z<2) (since between 1 and 2 std dev from the mean)
=0.475-0.3418
=0.3332
=33.32%
Answer:
its 48,868
Step-by-step explanation:
Answer:
£ 170 .
Step by step explanation :
Given that the price of a computer was decreased by 20% to £136. And we need to find the Original price before the decrease. So , let the earlier price be x ,
<u>Decrease in 20 % :- </u>
⇒ Decreased price = 20% of x
⇒ Decreased price = 20/100 × x
⇒ Decreased price = x/5
<u>New price :- </u>
⇒ New price = x - x/5
⇒ New price = 5x - x/5
⇒ New price = 4x/5.
But its given £ 136 , So
⇒ 4x/5 = £ 136
⇒ x = £ 136 * 5/4
⇒ x = £ 170
<h3>
<u>Hence</u><u> </u><u>the</u><u> Original</u><u> price</u><u> </u><u>was</u><u> </u><u>£</u><u> </u><u>1</u><u>7</u><u>0</u><u> </u><u>.</u></h3>
The following volumes of fluid can be added to 0.40 mL of liquid for the level of precision of 0.01 mL: a) 0.2 mL, b) 6 mL, c) 2.02 mL. The amounts 0.154 mL and 8.8331 mL are not possible due to given level of precision.
<h3>What is the amount of liquid to be added to sample according to a given precision?</h3>
If the measuring has a level of precision of 0.01 ml, this means that the <em>measured</em> quantities are only sensible to the <em>smallest</em> hundreths. Any change less than 0.01 ml and any decimal less than a hundreths are "invisible" for measuring processes.
Hence, the following volumes of fluid can be added to 0.40 mL of liquid for the level of precision of 0.01 mL: a) 0.2 mL, b) 6 mL, c) 2.02 mL. The amounts 0.154 mL and 8.8331 mL are not possible due to given level of precision.
