Answer:

Yes, it is reasonable to expect that more than one subject will experience headaches

Explanation:

Notice that where it says "assume that 55 subjects are randomly selected ..." there is a typo. The correct statement is "assume that 5 subjects are randomly selected ..."

You are given the table with the probability distribution, assuming, correctly, the binomial distribution with n = 5 and p = 0.732.

p = 0.732 is the probability of success (an individual experiences headaches).
n = 5 is the number of trials (number of subjects in the sample).

The meaning of the table of the distribution probability is:

The probability that 0 subjects experience headaches is 0.0014; the probability that 1 subject experience headaches is 0.0189, and so on.

To answer whether it is reasonable to expect that more than one subject will experience headaches, you must find the probability that:

X = 2 or X = 3 or X = 4 or X = 5

That is:

P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5).

That is also the complement of P(X = 0) or P(X = 1)

1 - P(X = 0) - P(X = 1)

From the table:

P(X = 0) = 0.0014
P(X = 1) = 0.0189

Hence:

1 - P(X = 0) - P(X = 1) = 1 - 0.0014 - 0.0189 = 0.9797

That is very close to 1; thus, it is highly likely that more than 1 subject will experience headaches.

In conclusion, yes, it is reasonable to expect that more than one subject will experience headaches

Cannnn u helpp me ill be choosing brainliest

allochka39001 [22]

$1) y=-5^{-x}, y = x+5 ,
\\ \\ -5^{-x}=x+5
\\ \\ ln(-5^{-x})=ln(x+5)
\\ \\ ln(- \frac{1}{5^{x}} )=ln(x+5),

you cannot find ln of negative number, so it is going to be

 "0" solutions.
$

The graphs of these equations will not intersect.

$2) y = 4(1.2)^{x}, y = x+7
\\ \\ x+7= 4(1.2)^{x}

graphs have 2 intersects, so two solutions.$

3) $y= {0.5}^{x} , y =6, \ 6=0.5^{x}

One intercept. so one solution$

Pls help asap ily

STatiana [176]

Answer:

2 hours

Step-by-step explanation:

you can write two linear equations and then set them equal to each other to see when they intersect. so for the first equation which will be representing the junior space cadets distance from his house. this can be written as

d = 50t + 50

where t represents time and d represents distance. there is 50 being added to the equation since he had already been traveling for an hour

the second equation which will represent his sister Gwen can be represented as

d = 75t

Now we set them equal to each other

50t + 50 = 75t

50 = 25t

2 = t
