slope = -7/4

Step-by-step explanation:

Plug the points into this formula: $\frac{y2 - y1}{x2 - x1}$

Plug in

$\frac{-2 - 19}{8 - (-4)} \\\\\frac{-21}{12} = -7/4$

The simplest form is -7/4

You measure the lifetime of a random sample of 25 rats that are exposed to 10 Sv of radiation (the equivalent of 1000 REM), for

Slav-nsk [51]

Answer:

CI 95%(μ)= [13.506 ; 14.094]

Step-by-step explanation:

The confidence interval (CI) formula is:

CI (1-alpha) (μ)= mean+- [(Z(alpha/2))* σ/sqrt(n)]

alpha= is the proportion of the distribution tails that are outside the confidence interval. In this case, 5% because 100-90%

Z(5%/2)= is the critical value of the standardized normal distribution. In this case is 1.96

σ= standard deviation. In this case 0.75 day

mean= 13.8 days

n= number of observations . In this case 25

Then, the confidence interval (90%) is:

CI 95%(μ)= 13.8+- [1.96*(0.75/sqrt(25)]

CI 95%(μ)= 13.8+- [1.96*(0.75/5) ]

CI 95%(μ)= 13.8+- (0.294)

CI 95%(μ)= [13.8-0.294 ; 13.8+0.294]

CI 95%(μ)= [13.506 ; 14.094]

Last year Baron Enterprises had $800 million of sales, and it had $270 million of fixed assets that were used at 65% of capacity

Svetllana [295]

Answer: B. $430.80

Step-by-step explanation:

Given : Last year Baron Enterprises had $800 million of sales.

It had $270 million of fixed assets that were used at 65% (=0.65) of capacity last year.

Now, the used asset = $0.65\times270=\$175.5$ million

Now, Baron Enterprises had $800 million of sales in $175.5 million of assets , if we use all of $270 million of fixed assets , then the sales will be :-

$\dfrac{800}{175.5}\times270=1230.76923077\approx1230.80\text{ million}$

Now, the increase in Baron's sales before it is required to increase its fixed assets = $\$1230.80-$800=\$430.80\text{ millions}$

Hence, the increase in Baron's ( in million ) sales before it is required to increase its fixed assets = $430.80
