Answer:

7 / 20

Step-by-step explanation:

To find the probability, we will find the total number of guinea pigs infected.

<h2>(50 + 125) / 500 =</h2><h2>= 175 / 500</h2><h2>= 7 / 20.</h2>

The probability of the guinea pigs being affected is 175 / 500 = 7 / 20.

1) Jo Anne needs to do a speech in her English class that can't be more than 4 minutes
djyliett [7]

Answer:

( 0 < y < 23 / 6 ) mins

Step-by-step explanation:

Solution:-

We will define a variable ( x ) as the time it took for Jo Anne to give her speech at home.

The time taken to give her speech must always be less than 4 minutes. We can express this mathematically using an inequality as follows:

                              ( 0 < x < 4 ) minutes

Jo Anne gave her speech which was 10 seconds less than the one she practised at home. We will convert the time in seconds to minutes as follows:

                             10 s * \frac{min}{60 s}  = \frac{1}{6} min

The time taken by Jo Anne to complete her speech in English class can be represented as:

                             y = x - 1/6

Using the range of time that Jo Anne could take in delivering her speech in the class would be:

                                    0 < x < 4

                            0 - 1/6 < y < 4 - 1/6

                            -1/6 < y < 23 / 6

Since time can not be less than zero. We correct the lower limit to " 0 " as follows:

                              ( 0 < y < 23 / 6 ) mins

Fernanda runs a large bowling league. She suspects that the league average score is greater than 150 per
murzikaleks [220]

Answer:

1.20

Step-by-step explanation:

Let mean be represented by M and standard deviation by d. The score will be x and sample number of games be n

To get the test statistic, t for Fernanda's test, we use the formula

t=\frac {M-x}{\frac{s}{\sqrt n}}

Substituting 156 for mean, M then 150 for score x and 30 for standard deviation while 36 for n then

t=\frac {156-150}{\frac{30}{\sqrt 36}}

t=1.20 when put in two decimal place
