KengaRu [80]

Answer:

If the question does not limit man to produce only one model of club, then the maximized profit of every condition produced under 50 sets daily will be all model A exclusive. such as $60 x 50 (model A) , even just produce 49 set that day, the maximal profit is still $60 x 49.

Step-by-step explanation:

If the question does not limit man to produce only one model of club, then the maximized profit of every condition produced under 50 sets daily will be all model A exclusive. such as $60 x 50 (model A) , even just produce 49 set that day, the maximal profit is still $60 x 49.

Re-consider the logic of the question ....

leo knows that each time a digit moves one place to the left in a whole number the value of the digit is 10 times as much. descr

Serga [27]

Answer:

Leo is true for any numbers (including decimal numbers)

Step-by-step explanation:

* Lets explain how to solve the problem

- In number 256

# 6 is the unit digit (one digit)

# 5 is the ten digit (10 digit)

# 2 is the hundred digit (100 digit)

- If we change the number to 2563

# 6 digit is moved 1 place to the left now its place changed from unit

digit to ten digit (from 1 to 10) that means 6 in the second number

is 10 times the 6 in the first number

# 5 digit is moved 1 place to the left now its place changed from ten

digit to hundred digit (from 10 to 100) that means 5 in the second

number is 10 times the 5 in the first number

# 2 digit is moved 1 place to the left now its place changed from

hundred digit to thousand digit (from 100 to 1000) that means 2

in the second number is 10 times the 2 in the first number

- In number 2.345

# 2 is the unit digit (one digit)

# 3 is the tenth digit (1/10 digit)

# 4 is the hundredth digit (1/100 digit)

# 5 is the thousandth digit (1/1000 digit)

- If we change the number to 23.45

# 3 digit is moved 1 place to the left now its place changed from tenth

digit to unit digit (from 1/10 to 1) that means 3 in the second number

is 10 times the 3 in the first number

# 4 digit is moved 1 place to the left now its place changed from

hundredth digit to tenth digit (from 1/100 to 1/10) that means 4 in the

second number is 10 times the 5 in the first number

# 5 digit is moved 1 place to the left now its place changed from

thousandth digit to hundredth digit (from 1/1000 to 1/100) that means

5 in the second number is 10 times the 5 in the first number

∴ Leo is true for any numbers (including decimal numbers)

A) American households spent an average of about $44 in 2007 on Halloween merchandise such as costumes, decorations and candy. T

anygoal [31]

A)

<h3>The sample mean is 52</h3><h3>The claimed population mean is 44</h3>

---------

The sample mean is the mean found in the survey (of the sample of people). The sample mean is found by adding up the values and dividing by the sample size n. The larger n gets, the closer the sample mean should get to the population mean. This is assuming the sample is random and representative of the population.

The population mean is a claim made by another study/survey/etc. Usually generalized statements such as "Americans spent an average of X dollars (in year Y)" would have X be considered the population mean.

==================================

B)

<h3>Sample mean is 3.42</h3><h3>Claimed population mean is 3.56</h3>

--------

Same idea as part A, but we're using different numbers and a different problem context.

==================================

Note: The year numbers and the sample sizes are not used to answer any of the four questions above.

A survey showed that 77% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 22 adults are

Sveta_85 [38]

Answer:

The probability that no more than more than 11 of them need correction for their eyesight is 0.00512

No, 11 is not a significantly low low number of adults requiring eyesight correction .

Step-by-step explanation:

A survey showed that 77% of adults need correction for their eyesight.

If 22 adults are randomly selected, find the probability that no more than more than 11 of them need correction for their eyesight.

n =22

p = 0.77

q = 1-p = 1- 0.77=0.23

We are supposed to find $P(x\leq 11)$

$P(x\leq 11)=P(x=1)+P(x=2)+P(x=3)+.....+P(x=11)$

Formula : $P(x=r)=^nC_r p^r q^{n-r}$

$P(x\leq 11)=^{22}C_1 (0.77)^1 (0.23)^{22-1}+^{22}C_2 (0.77)^2 (0.23)^{22-2}+^{22}C_3 (0.77)^1 (0.23)^{22-3}+.....+^{22}C_{11} (0.77)^1 (0.23)^{22-11}$

Using calculator

$P(x\leq 11)=0.00512$

So, The probability that no more than more than 11 of them need correction for their eyesight is 0.00512

No, 11 is not a significantly low low number of adults requiring eyesight correction .
