How do you Write 205,000,090 as a single digit times a power of 10

andrey2020 [161]

205,000,090 as a single digit times a power of 10 can be written as 2.0500009 × 10⁸ by using multiplication, decimal, exponents and powers.

We are given a number:

205,000,090

We need to represent it as a single digit times a power of 10.

For this, we will have to use three things:

1) exponents and powers

2) multiplication

3) decimal

So that we can represent it in a single digit number and as a power of 10.

So, we can also write it as:

205,000,090 = 2.0500009 × 10⁸

where 8 is a power of 10 in exponent form

multiplication is used so that the value of number remains the same

and decimal is used to represent it in a single digit number.

Therefore, we get that, 205,000,090 as a single digit times a power of 10 can be written as 2.0500009 × 10⁸ by using multiplication, decimal, exponents and powers.

Answer:

Q10. (1,4)

Q11. No solution

Step-by-step explanation:

Q10. To solve equations by graphing, sketch the graphs of the 2 equations. The point(s) where the two lines intersect is the solution. To sketch straight line graph, find 2 coordinates then join them.

y= -2x +6

When x=0, y= 6

When y=0,

-2x+6=0

2x=6

x=6÷2

x=3

Thus, the 2 coordinates are (0,6) and (3,0).

After plotting these 2, draw a straight line that passes these 2 points. Instead of finding the x and y coordinates, you could also find other points such as when x=5 etc.

y=4x

when y=0,

4x=0

x=0

When x=1,

y=4(1)

y=4

The 2 coordinates are (0,0) and (1,4).

Plot this graph.(1st picture) You should be able to see the point if intersection, and that is the solution.

The solution should be (1,4).

Q11. Like question 10, plot the 2 graphs and see where they intersect.(2nd picture) In this case, you would notice that the two lines does not intersect. Hence, there is no solution.

Further explanation:

This is because the first equation is y= -2x+6 and the second is y= -2(x-6). If you expand the 2nd equation, the equation is y= -2x+12.

The gradient of the two lines are the same, which means that they are parallel and therefore they do not meet.

In a survey of 329 people who attended a local professional soccer team’s most recent home game, 141 said that they were fans of

Verdich [7]

Answer: (0.3751,0.4821)

Step-by-step explanation:

Given : Level of significance : $1-\alpha:0.95$

Then , significance level : $\alpha: 1-0.95=0.05$

Since , sample size : $n=329$ , i.e. a large sample (n<30).

Then we use z-test.

Using excel (by going in formulas for more statistics and then statistics), Critical value : $z_{\alpha/2}=1.96$

Also, the proportion of people said that they were fans of the visiting team :-

$\hat{p}=\dfrac{ 141}{329}\approx 0.4286$

The confidence interval for population proportion is given by :-

$\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$0.4286\pm(1.96)\sqrt{\dfrac{0.4286(1-0.4286)}{329}}\\\\\approx0.4286\pm0.053\\\\=(0.4286-0.0534, 0.4286+0.053=(0.3751,\ 0.4821)$

Hence, a 95% confidence interval for the population proportion of attendees who were fans of the visiting team= (0.3751,0.4821)
