Arrange the number in ascending order I.e 1,2,5,8,

The number is 5figure, add 1 to it I.e

(5+1)/2=3

So the third number is the median.

5 is the median

An expression that is equivalent to (-8a-1)-(-7a+5)

horrorfan [7]

Answer:

Step-by-step explanation:

(-8a - 1)- (-7a + 5) = -8a - 1 - 7a*(-1) + 5*(-1) { (-1) is disturbed to all the terms in (-7a +5)}

= -8a - 1 + 7a - 5

= -8a + 7a -1 - 5 {Combine like terms}

= -a - 6

What is the APY of a savings account with an APR of 3.9742% compounded monthly? Answer to the four decimal place

Maurinko [17]

Answer:

The APY of the saving account is 4.0474%

Step-by-step explanation:

We know the formula for APY which is given by

$APY=(1+\frac{r}{n} )^n-1$

here, r= interset rate = 3.9742% = 0.039742

n = compounding cycles = 12

On plugging these values in the above formula, we get

$APY=(1+\frac{0.039742}{12} )^{12}-1$

On simplifying this we get

APY =0.04047395=4.0474%

The Insure.com website reports that the mean annual premium for automobile insurance in the United States was $1,503 in March 20

stira [4]

Answer:

a) Option A)

$H_{0}: \mu \geq 1503\\H_A: \mu < 1503$

b) Point estimate of difference = -78

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = $1,503

Sample mean, $\bar{x}$ = $1,425

Sample size, n = 25

Sample standard deviation, s = $160

We have to carry a hypothesis test that the mean annual premium in Pennsylvania is lower than the national mean annual premium.

a) First, we design the null and the alternate hypothesis

$H_{0}: \mu \geq 1503\text{ dollars}\\H_A: \mu < 1503\text{ dollars}$

b) Point estimate of the difference between the mean annual premium in Pennsylvania and the national mean

Point estimate of difference =

Mean annual premium in Pennsylvania - National mean

$\text{Point estimate} = \bar{x} - \mu = 1425 - 1503 = -78$

Thus,

Point estimate of difference = -78
