4. As part of a promotion for a new type of cracker, free samples are offered to shoppers in a local supermarket. The probabilit
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:

And the deviation is given by:

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

6. Write this equation in slope-intercept form. 7x = 3y - 12 ​
Doss [256]

Answer: is y=7/3x+4

Step-by-step explanation:

1) add twelve to both sides- this will cancel out the 12

2)you now have 7x+12=3y

3) divide three on both sides. note you put everything over three on the left

4) 7 over 3 (x)+4=y is what you get when you finish doing the simple computations

5) flip the whole thing around so it fits the form. remember that addition can be anywhere as long as you don't switch sides of the equation

you will get: y=7/3x+4

Firdavs [7]

Answer:

1.) 120? (Same angle just flipped around.)

2.) -2 (you flip the stuff: (3,2)(4,6) = (3,4) (2,6)

it's x1,y1, x2, y2 for number 2.. That's the formula.
