Answer:

The probability that odd turn up is:

P(odd)=5/8

Step-by-step explanation:

We are given a spinner numbered as:

1 , 2 , 3 , 3 , 4 , 5 , 5 , 6.

i.e. the spinner is divided into eight sections out of which the odd number is in 5 sections.

( since the numbers are:

1 , 3 , 3 , 5 , 5 )

Hence, the number of sections numbered odd=5.

Total number of sections=8

Let P denote the probability of an event.

Hence,

P(odd)=Number of sections numbered odd/Total number of sections

Hence,

P(odd)=5/8

You just have to add or subtract the percent of a number from the original

A) 5percent of 40=2 ( 0.05*40)
Since it’s increase add 2 to 40=42

F) 40percent of 25= 10 (0.4* 25)

X+23=-22
  -23   -23

x=-45

a+(-1.3)=-4.5
        
         or

a-1.3+-4.5
  +1.3  +1.3

a=3.2

A rectangular garden has length and width as given by the expressions below.
Tom [10]

Answer:

P = -12xy - 56y - 42x + 8

Step-by-step explanation:

                                    P = 2L + 2W

P = 2(4 - 7(3x + 4y)) + 2(3x(-2y))

P = 8 - 14(3x + 4y) + 6x(-2y)

P = 8 - 42x - 56y - 12xy

                              P = -12xy - 56y - 42x + 8

Answer:

MOE_{95} = 1.192\cdot MOE_{90}

Step-by-step explanation:

The margin of error is computed using the formula:

MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}

The critical of <em>z</em> for 95% confidence level and 90% confidence level are:

z_{0.05/2}=z_{0.025}=1.96\\\\z_{0.10/2}=z_{0.05}=1.645

*Use a <em>z</em>-table.

The sample size is n = 44.

Compare the MOE for 95% confidence level and 90% confidence level as follows:

\frac{MOE_{95}}{MOE_{90}}=\frac{1.96\times (15/\sqrt{44})}{1.645\times (15/\sqrt{44})}

\frac{MOE_{95}}{MOE_{90}}=\frac{1.96}{1.645}\\\\\frac{MOE_{95}}{MOE_{90}}=1.192\\\\MOE_{95} = 1.192\cdot MOE_{90}
