5 0

Answer:

3. 15 baskets

4. 16 tries

Step-by-step explanation:

3.

3: 4 is ratio so 3:4=x:20, 3/4=x/20, and you get x=15

4. ratio is still 3:4, 3:4=12:x, 3/4=12/x, x=16, so 16 tries

Suppose a large shipment of laser printers contained 18% defectives. If a sample of size 340 is selected, what is the probabilit
lukranit [14]

Answer:

The probability that the sample proportion will be greater than 13% is 0.99693.

Step-by-step explanation:

We are given that a large shipment of laser printers contained 18% defectives. A sample of size 340 is selected.

Let \hat p = <u><em>the sample proportion of defectives</em></u>.

The z-score probability distribution for the sample proportion is given by;

                         Z  =  \frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n}}  }  ~ N(0,1)

where, p = population proportion of defective laser printers = 18%

            n = sample size = 340

Now, the probability that the sample proportion will be greater than 13% is given by = P(\hat p > 0.13)

         P(\hat p > 0.13) = P( \frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n}}  } > \frac{0.13-0.18}{\sqrt{\frac{0.13(1-0.13)}{340}}  } ) = P(Z > -2.74) = P(Z < 2.74)

                                                                      = <u>0.99693</u>

The above probability is calculated by looking at the value of x = 2.74 in the  table which has an area of 0.99693.

Hunter-Best [27]

Answer:

0.7 , 0.251 , 0.18 , 0.171

Step-by-step explanation:

0.7 is highest 0.251 is 2nd highest 0.18 is lower and 0.171 is lowest as it is simplified to 0.17 to which is lower than 0.18. I am only 8 years old and you should thank me so yeah.

У = 3х - 17<br> for x it lists 3, 4,5,6 <br> i don’t know what to put for y
Brut [27]

Answer:

x = 3, y = -8

x = 4, y = -5

x = 5, y = -2

x = 6, y = 1

Step-by-step explanation:

You can apply the equation y = 3x - 17 for the different values for x.

x = 3

y = 3(3) - 17

  = 9 - 17

  = -8

x = 4

y = 3(4) - 17

 = 12 - 17

 = -5

x = 5

y = 3(5) - 17

  = 15 - 17

  = -2

x = 6

y = 3(6) - 17

  = 18 - 17

  = 1
