The following function represents the value of a house, in dollars, after x years: f(x) = 242,000(1.04)x What does 1.04 represen

zmey [24]

The number 1.04 represents the rate at which the house appreciates, or increases in its price annually.

As according to the values of an exponential equation, which is represented by this: y=ab^x, the a value represents the original price, the b value represents the rate of growth/decay (if growth, you add 1 to the rate, if decay, you subtract the rate from 1), and x represents the amount of times it decays or grows.

As according to the function <span> f(x) = 242,000(1.04)^x, 242,000 is the original price and 1.04 is the rate of growth since 1 has been added to the the 4% annual growth.</span>

deff fn [24]

Answer: 38.41 minutes

Step-by-step explanation:

The standard error for the difference in means is given by :-

$SE.=\sqrt{\dfrac{\sigma_1^2}{n_1}+\dfrac{\sigma^2_2}{n_2}}$

where , $\sigma_1$ = Standard deviation for sample 1.

$n_1$ = Size of sample 1.

$\sigma_2$ = Standard deviation for sample 2.

$n_2$ = Size of sample 2.

Let the sample of Latino name is first and non -Latino is second.

As per given , we have

$\sigma_1=82$

$n_1=9$

$\sigma_2=101$

$n_2=14$

The standard error for the difference in means will be :

$SE.=\sqrt{\dfrac{(82)^2}{9}+\dfrac{(101)^2}{14}}$

$SE.=\sqrt{\dfrac{6724}{9}+\dfrac{10201}{14}}$

$SE.=\sqrt{747.111111111+728.642857143}$

$SE.=\sqrt{1475.75396825}=38.4155433158\approx38.41$

Hence, the standard error for the difference in means =38.41 minutes

Given right triangle jkl, what is the value of cos(l)?

miss Akunina [59]

Taking K as the right angle =>

Convert the following metric units of weight. a. 40 centigrams to grams b. 53 milligrams to grams c. 0.54 grams to decigrams d.

liubo4ka [24]

Answer:

a) $0.4$ grams

b) $0.053$ grams

c) $5.4$ decigrams

d) $2300$ milligrams

Step-by-step explanation:

a)

To convert centigrams to grams you have to divide by 100.

$40$ centigrams = $\frac{40}{100}$ grams

= $0.4$ grams

b)

To convert milligrams to grams you have to divide by 1000.

$53$ milligrams = $\frac{53}{1000}$ grams

= $0.053$ grams

c)

To convert grams to decigrams you have to multiply by 10.

$0.54$ grams = $0.54*10$ decigrams

= $5.4$ decigrams

d)

To convert grams to milligrams you have to multiply by 1000.

$2.3$ grams = $2.3*1000$ milligrams

= $2300$ milligrams
