The length of a rectangle is 3 units greater than its width. If the width is w, what expression gives the perimeter of the recta

Andru [333]

Step-by-step explanation:

let width be "w"

given,length of rectangle is 3 units greater than its width

length= w+ 3

perimeter of rectangle= 2( l+ b)

= 2[( w+3)+ w]

= 2(w to the power of 2 + 3w)

= 2w to the power of 2 + 6w

is the answer

A surgical technique is performed on seven patients. You are told there is a 70% chance of success. Use a table to find the prob

kiruha [24]

Answer:

31.77% probability the surgery is successful for exactly five patients.

Step-by-step explanation:

For each patient, there are only two possible outcomes. Either the surgery is successful, or it is not. The probability of the surgery being successful for a patient is independent of other patients. So we use the binomial probability distribution to solve this question.

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 combinations 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.

A surgical technique is performed on seven patients.

This means that $n = 7$

You are told there is a 70% chance of success.

This means that $p = 0.7$

Find the probability the surgery is successful for exactly five patients.

This is P(X = 5).

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

$P(X = 5) = C_{7,5}.(0.7)^{5}.(0.3)^{2} = 0.3177$

31.77% probability the surgery is successful for exactly five patients.

Please help! I will mark the brainliest!

The first is in the form y=Mx+b where m is the slope and b is the y-intercept. Start at 600 on the y-axis and graph with a slope of six. The second is in the same form but the y-intercept is 0, so start at the origin and graph with a slope of 8. The last is in the form y=b+mx, so start at 1300 and graph with a slope of 3. Remember, slope is rise/run or (change in y)/(change in x). Since the domain and range start at 0 these graphs will only be in the first quadrant with an x limit of 650 and a y limit of 1500.
