A recent survey found that 70% of all adults over 50 wear
lubasha [3.4K]

Answer:

There is an 84.97% probability that at least six wear glasses.

Step-by-step explanation:

For each adult over 50, there are only two possible outcomes. Either they wear glasses, or they do not. This means that we use the binomial probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinatios of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In this problem we have that:

n = 10, p = 0.7

What is the probability that at least six wear glasses?

P(X \geq 6) = P(X = 6) + `P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) = 0.8497

There is an 84.97% probability that at least six wear glasses.

Graph y = | x | + 5 .
vovikov84 [41]
I cannot see the images, but... 

y = | x | + 5 

consider the absolute value function. You know that for every value of x, y will be greater than or equal to 5.  this means that the y-intercept will also be the bottom of the curve. 

Plug a few values in for an idea of what the graph will look like: 
f(-1) = 6    (-1,6)
f(1) = 6     (1, 6)
f(-2) = 7    (-2, 7)
f(2) = 7     (2, 7)

The graph will have a minimum value at (0,5), where two lines will converge. The graph will look like a pointy cone with its point at (0,5), with two lines pointing outward and upward from this point. Confirm that the graph passes through the coordinates provided above!

Given h(x) = 3x - 3, find h(3).
Daniel [21]

Answer:

<h2>h(3) = 6</h2>

Step-by-step explanation:

h(x) = 3x - 3

To find h(3) , substitute the value of x that's 3 into h(x). That is for every x in f (x) replace it with 3

We have

h(3) = 3(3) - 3

= 9 - 3

We have the final answer as

<h3>h(3) = 6</h3>

Hope this helps you

Kent walked to the bus stop, then sat and waited until the bus arrived. He rode the bus for 25 minutes, then walked the last 3 b
zaharov [31]
We are given a scenario and asked to choose which graph (described verbally) represents the scenario.
Let us break down the scenario piece by piece.
The first part of the scenario is that Kent walked to the bus station. His speed will be constant so that graph will show a line sloping upward.
Next, Kent waited for the bus. This will be represented by a horizontal line.
Then, he rode the bus. This will be represented by a sloping line but steeper than the first part of the graph since the speed of the bus is greater than Kent's speed.
Finally, Kent walked to work. The graph would still be a sloping line but the slope will be less than the previous part of the graph.
So, the answer is
<span>The line increases for 10 minutes, stays horizontal for 15 minutes, increases rapidly for another 25 minutes, then increases slowly for 5 minutes.</span>
