Answer:

The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y. The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept

In a study by Peter D. Hart Research Associates for the Nasdaq Stock Market, it was

GrogVix [38]

Answer:

a) 0.1108

(b) 0.0173

Step-by-step explanation:

We are given that 20% of all stock investors are retired people. A random sample of 25 stock investors is taken.

Firstly, the binomial probability is given by;

where, n = number of trails(samples) taken = 25

r = number of successes

p = probability of success and success in our question is % of

retired people i.e. 20%.

Let X = Number of people retired

(a) Probability that exactly seven are retired people = P(X = 7)

P(X = 7) =

= = 0.1108

(b) Probability that 10 or more are retired people = P(X >= 10)

P(X >= 10) = 1 - P(X <= 9)

Now, using binomial probability table, we find that P(X <= 9) is 0.98266 at n = 25, p = 0.2 and x= 9

So, P(X >= 10) = 1 - 0.98266 = 0.0173.

Train completes journey of 150 miles one hour earlier if original speed is increased by 5mes/hour What is original speed

bija089 [108]

25mph.

using the equation distance = speed x time, you can make 2 equations. let x be the original speed of the train, and t be the original time it takes. the first equation is the original trip, the 2nd is your new speed and shortened time.
$150=xt \\ 150=(x+5)(t-1)$
this is because you are adding 5mph, and taking off 1 hour of time, to still cover the 150 miles. you can solve the first equation for t, and substitute into the second, and then solve for x.
$t= \frac{150}{x} \\ 150=(x+5)(t-1)=xt+5t-x-5 \\ 150=150+5( \frac{150}{x})-x-5 \\ 5= \frac{750}{x} -x \\ 5+x= \frac{750}{x} \\ x^2+5x=750 \\ x^2+5x-750=0$
and using the quadratic formula you can find x=25.
