Step-by-step explanation:

Hey, so when I was solving this I accidentally numbered the exercises differently than in your pic....

I just went from the left row to the right (and missed two...)

Hope it doesn't confuse you :]

If you have any questions about the way I solved it, don't hesitate to ask me =)

Which is the best estimate for StartFraction (8.9 times 10 Superscript 8 Baseline) Over (3.3 times 10 Superscript 4 Baseline) En

ratelena [41]

Answer:

$2.7 * 10^{4}$

Step-by-step explanation:

Given the expression $\frac{8.9*10^{8} }{3.3*10^{4} }$ , to express the the fraction in scientific notation, we will apply the law of indices below;

According to one of the laws of indices, $\frac{a^{m} }{a^{n} } = a^{m-n}$

Applying this to the fraction;

$= \frac{8.9*10^{8} }{3.3*10^{4} }\\\\= \frac{8.9}{3.3} * \frac{10^{8} }{10^{4} }\\\\ = \frac{8.9}{3.3} * 10^{8-4}\\\\ = \frac{8.9}{3.3} *10^{4}\\\\ = 2.697 * 10^{4}$

The best estimate for the fraction in scientific notation will be $2.7 * 10^{4}$

Hi there

2%=0.02

2% of 870

0.02×870=17.4
whichever is higher
20 is higher than 2%

So the minimum monthly payment is
20

Good luck!

The perimeter of a rectangle playground is 40 yards it is 1 1/2 yards longer than it’s Wide what is the area of the playground

raketka [301]

The solution to the problem is shown below:
Perimeter = 40 yardsWide = W =?Length = W + 1.5 yards
The formula for the perimeter of a rectangular playground:P=2(L+W) where "L" is for the length and "W" is for the Width40 = 2( (W+1.5) + W )40 = 2(2W+1.5)40/2=2W + 1.520 - 1.5 =2WW=9.25L=9.25 + 1.5 =10.75
Area is L x WArea = 9.25 x 10.75Area = 102.125 squard unit

(2 points) The least squares method requires that the variance σ2????σϵ2 of the error variable ????ϵ is a constant no matter wha

attashe74 [19]

Answer:

C. heteroscedasticity

Step-by-step explanation:

The OLS regression assumption of error variance being constant irrespective of independent variables, is called Homoscedasticity.

Var (u | x) = σ^2 (u) ;

where u = error term, x = independent variable, σ^2 (u) = constant error variance

The violance of this assumption ie Var (u | x) is related to independent variable x, is called Heteroscedasticity.
