Information on a packet of​ seeds, which may not be a random sample of​ seeds, claims that the germination rate is 94​%. ​What's
Evgesh-ka [11]

Answer:

0.1052

Step-by-step explanation:

Given that proportion of germination in the population is 94% =0.94

p = 0.96

Sample size = 220

Std dev of p = \sqrt{\frac{pq}{n} } \\=0.016

The probability that more than 96​% of the 220 seeds in the packet will​ germinate

= P(p\geq 0.96)\\=P(Z\geq \frac{0.96-0.94}{0.016})\\=P(Z\geq 1.25)\\==1-0.8948\\=0.1052

Assumptions are np and nq >5 and also sample size >220 hence normal

The value of the 9 is ten times the value of the 9 in 329,513. The value of the 2 is one-tenth the value of the 2 in 7,562. The
nexus9112 [7]

Answer: The number is 90,000.26

Step-by-step explanation:

Extracting key information from the question:-

*** The value of the "9" in Lea's riddle is 10 times the one in 329,513

*** The value of the "2" in the riddle is 1/10 the value of the 2 in 7,562.

*** The value of the 6 in the riddle is one-tenth the value of the 6 in 4.68

*** We are required to solve this possible and reveal the number.

Now, in the number 329,513 the place value of 9 is 9,000. According to the information provided, the value of the 9 in the riddle is ten times the value of the 9 in 329,513.

So, multiplying 9000 by 10 gives:-

9,000 × 10

= 90,000

Again, the value of the 2 in the riddle is one-tenth (1/10) the value of the 2 in 7,562. The value of 2 in 7,562 is 2 units, therefore one-tenth of this 2 units will give:-

1/10 × 2

= 0.2

Similarly, the value of 6 in the puzzle is one-tenth (1/10) the value of the 6 in 4.68; The 6 here is 6 hundredth = 0.6

Therefore, the value of 6 in the puzzle is:

1/10 × 0.6

= 0.06

In order to discover the number in Lea's riddle, we will then add up the calculated values:-

= 90,000 + 0.2 + 0.006

= 90,000.26

This number is the answer to Lea's riddle.
