The sides of a rectangle are 3t - 2 and 5t + 7. Write an expression for the perimeter of the rectangle.

1 answer:

6 0

How does this have anything to do with factoring?
Perimeter of the rectangle would just be 2(3t-2)+2(5t+7)
Simplify that to get 6t-4+10t+14, then 16t+10

Tickets to a local basketball team's games cost $12 each. Brendon and Ed each bought tickets to four games. How much did they sp

den301095 [7]

Answer:

total amount spent is $96 altogether on tickets

Step-by-step explanation:

Step 1

Derive the expression for the total amount Brendon spent on the tickets as follows;

total amount=cost per ticket×number of tickets bought

where;

cost per ticket=$12

number of tickets Brendon bought=4

replacing;

total amount=(12×4)=48

total amount spent by Brendon=$48

Step 2

Derive the expression for the total amount Ed spent on the tickets as follows;

total amount=cost per ticket×number of tickets bought

where;

cost per ticket=$12

number of tickets Ed bought=4

replacing;

total amount=(12×4)=48

total amount spent by Ed=$48

Step 3

Total amount spent altogether=total amount spent by Ed+total amount spent by Brendon

replacing;

Total amount spent altogether=(48+48)=96

They spent Derive the expression for the total amount Brendon spent on the tickets as follows;

total amount=cost per ticket×number of tickets bought

where;

cost per ticket=$12

number of tickets Brendon bought=4

replacing;

total amount=(12×4)=48

total amount spent is $96 altogether on tickets

Suppose a random sample of n measurements is selected from a binomial population with probability of success p = .39. Given n =

Oksi-84 [34.3K]

Answer:

The answer is below

Step-by-step explanation:

a) Given that the number of sample (n) = 300, therefore since n > 30, the distribution of the sample means is going to be normally distributed.

b) The mean of the distribution of sample means (also known as the Expected value of M) is equal to the population mean μ.

$\mu_x=\mu=np=300*0.39=117$

c) The standard deviation of the distribution of sample means is called the Standard Error of M, it is given by:

$\sigma_x=\sqrt{np(1-p)} =\sqrt{300*0.39(1-0.39)} =8.44$

How do you rearrange the equation (2x) /(4pi) +((1-x) /2) =0 to solve for x?

USPshnik [31]

$\frac{2x}{4 \pi } + \frac{1-x}{2} =0 \\ 
 \frac{x}{2 \pi } + \frac{1-x}{2} = 0$
Then we will multiply both sides of the equation by 2 π :
x + π ( 1 - x ) = 0
x + π - π x = 0
x ( 1 - π ) = - π / · ( - 1 )
x ( π - 1 ) = π
x = π / ( π - 1 )
