A political pollster wants to know what proportion of voters are planning to vote for the incumbent candidate in an upcoming ele

balandron [24]

Answer:

$1.\ \ np\geq 10\\\\2.\ \ n\geq 10x$

Step-by-step explanation:

-Let x be the sample size and n the population size

-The conditions for a one-sample proportion z-test are:

-The sample is randomly selected from the population.

-The sample size is greater than or equal to ten times the population size:

$n\geq 10x\\\\n=2000\\x=150\\10x=1500\\\therefore n\geq 10x$

-The expectation np is greater than or equal to 10:

$np\geq 10\\n=2000, p=0.6\\np=1200\\\\Hence, np\geq 10$

Sal Boxer decided to divide a gift of $5000 into two different accounts. He placed $1000 in an account that earns an annual simp

mash [69]

Answer:

THE TOTAL INTEREST EARNED = $ 385

Step-by-step explanation:

Interest earned by sal from first account can be calculated as follows :

Principal value (P) = $1000 .

interest rate (R) = 7.5 % .

Time period (T) = 1 year .

$\textbf{S . I} =\frac{\texbf{P * R * T}}{\textbf{100}}$

$= \frac{1000 * 7.5 * 1}{100}$

= $ 75 .

SIMILARLY , we can find the intrest earned by rest amount.

Principal value (P) = $5000 - $ 1000 = $ 4000 .

Interest rate (R) = 7.75 % .

Time period (T) = 1 year .

$S . I = \frac{4000 * 7.75 * 1}{100}$

= $ 310 .

THE TOTAL INTEREST EARNED = $ 75 + $ 310

= $ 385

Solve the following system of equations using elimination (Do not multipy)

aivan3 [116]

1) 5x - 6y = -32 --> equation 1
3x + 6y = 48 --> equation 2
eliminating y from both of the equations and adding the rest of the terms
we get,
8x = 16
dividing 8 on both sides
x = 2
Substituting the value of x in equation 1
5(2) - 6y = -32
10 - 6y = -32
-6y = -12 ( dividing both sides by -6)
y = 2

2) -3x - 3y = 9 ---> equation 1
3x - 4y = 5 --> equation 2
eliminating x from both equations and adding the rest of the terms
we get,
-7y = 14 ( dividing both sides by -7 )
y = -2
Substituting the value of y in the equation 1
-3x - 3(-2) =9
-3x + 6 = 9 (subtracting both sides by -6)
-3x = 3
x = -1

Hope this helps you.. :)
