Answer:

Step-by-step explanation:

Let 'x' be the original price.

x + 39% of x = 197.38

x + 0.39 x = 197.38

1.39x = 197.38

x = 197.38/ 1.39

x = 142

A bag contains green marbles and blue marbles,

dexar [7]

There are 13 green marbles in the bag.

Step-by-step explanation:

Total marbles = 18

Let,

Green marbles = x

Blue marbles = y

According to given statement;

The number of green marbles is 2 less than 3 times the number of blue marbles.

x = 3y-2 Eqn 1

x+y=18 Eqn 2

Putting value of x from Eqn 1 in Eqn 2;

$(3y-2)+y=18\\3y-2+y=18\\4y=18+2\\4y=20$

Dividing both sides by 4

$\frac{4y}{4}=\frac{20}{4}\\y=5$

Putting y=5 in Eqn 1

$x=3(5)-2\\x=15-2\\x=13$

There are 13 green marbles in the bag.

Given that a 95% confidence interval is (6.5, 12.5), we can state that there is a 95% probability that the true population mean

slavikrds [6]

Let
μ = population mean
σ = population std. deviation.
n = sample size.

At 95% confidence level, the confidence interval is
(μ - 1.96y, μ + 1.96y),
where y = σ/√n.

Therefore
μ - 1.96y = 6.5 (1)
μ + 1.96y = 12.5 (2)

Add (1 and (2) to obtain
2μ = 19
μ = 9.5

The calculated value of μ is within the interval (6.5, 12.5).

Answer:
The statement "There is a 95% probability that the true population mean is between 6.5 and 12.5" is True.
