PLEASE HELP ME FFS

Mathematics
1 answer:
AnnZ [28]3 years ago
7 0

Answer:

55.74

Step-by-step explanation:

<em>Since the culture was tested and then the countdown started, you need to multiply the initial value by 3.5. Since it is tested once every 15 minutes, it will be tested two more times by the time 30 minutes is up; a total of 3 times tested.</em>

1.3 x 3.5 = 4.55

4.5 x 3.5 = 15.925

15.925 x 3.5 = 55.7375

Based on housing data below which equation can be used to calculate fair housing prices?
VMariaS [17]

Answer:

B. y = 0.097x + 11.142

Step-by-step explanation:

In order to find the best equation to descibe the housing price, we have to calculate the slope of the line  first.

The equation of the line can be written as

y=mx+q

where m is the slope and q the y-intercept.

In order to have the most accurate estimate for the slope, we use the first point and the last point, that are:

(1900, 196)

and

(2200, 225)

The slope of the line is calculated as:

m=\frac{y_2-y_1}{x_2-x_1}=\frac{225-196}{2200-1900}=0.097

So, the slope of the line is 0.097.

Therefore, the correct option is the only one having a slope of 0.097, which is:

B. y = 0.097x + 11.142

seropon [69]

Answer: 0.064

Step-by-step explanation:

The formula to find the margin of error :-

E=z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}

Given : Significance level : \alpha=1-0.99=0.01

Critical value : z_{\alpha/2}=2.576

Sample size : n=400

The proportion of people support the candidate :p=0.44

Then , E=(2.576)\sqrt{\dfrac{0.44(1-0.44)}{400}}\approx0.064

Hence, Margin of error = 0.064
