Answer:

-1.4

-0.6

5.8

Answer:   -4/5

Step-by-step explanation:

you can use slope formula to solve this question. (Y1-Y2)/(X1-X2). So the answer to this question should be (0-4)/(5-0)=  -4/5

RUDIKE [14]

Answer:

For this case we need to check the conditions in order to use the normal approximation:

1) np = 60*0.3= 18>10

2) n(1-p) = 60*(1-0.3)= 42>10

Since both conditions are satisfied and the independence condition is assumed we can use the normal approximation given by:

\hat p \sim N (\hat p, \sqrt{\frac{\hat p(1-\hat p)}{n}})

The mean would be given by:

\mu_{\hat p}=0.3

And the deviation is given by:

\sigma_{\hat p}= \sqrt{\frac{0.3*(1-0.3)}{60}}= 0.0592

Step-by-step explanation:

For this case we know the following info:

n =60 represent the sample size

\hat p = 0.3 represent the estimated proportion of people that will buy a packet of crackers after tasting

For this case we need to check the conditions in order to use the normal approximation:

1) np = 60*0.3= 18>10

2) n(1-p) = 60*(1-0.3)= 42>10

Since both conditions are satisfied and the independence condition is assumed we can use the normal approximation given by:

\hat p \sim N (\hat p, \sqrt{\frac{\hat p(1-\hat p)}{n}})

The mean would be given by:

\mu_{\hat p}=0.3

And the deviation is given by:

\sigma_{\hat p}= \sqrt{\frac{0.3*(1-0.3)}{60}}= 0.0592

MARKING AS BRAINLIEST!! Starr if given functions are inverse)!
kifflom [539]

Answer: They are inverses of each other.

Explanation:

f(x) = -x+5

f(g(x)) = -(g(x)) + 5

f(g(x)) = -(-x+5) + 5

f(g(x)) = x - 5 + 5

f(g(x)) = x

The steps to show that g(f(x)) = x are identical to what is shown above. This is because both f(x) and g(x) are the same.

Since f(g(x)) = x and g(f(x)) = x are true, this means the functions are inverses of each other.
