Answer:  The required value is 36.

Step-by-step explanation:  We are to find the value of the following expression for m = -2 and n = 4 :

m^2-2mn+n^2.

Substituting the values m = -2 and n = 4 in the given expression, we get

m^2-2mn+n^2\\\\=(-2)^2-2\times (-2)\times 4+4^2\\\\=4+16+16\\\\=36.

Thus, the required value is 36.

Experiments with repeated independent trials will be described by the binomial distribution if
bija089 [108]

Answer:

d. each trial has exactly two outcomes whose probabilities do not change

Step-by-step explanation:

A binomial experiment is one where there are exactly two outcomes for each trial and probability for getting success is constant in each trial.

In other words, each trial is independent of the other.

The trials need not be continuous nor time between trials to be constant.

Since trials are to be independent, each trial cannot influence the next.

Only option d is right.

d. each trial has exactly two outcomes whose probabilities do not change

Examples are tossing of coins, throwing dice, drawing cards or balls with replacement, etc

line passes through the point (-3,-4) and its y-intercept is (o, -9). What is the equation of the line that is parallel to the f
12345 [234]

Answer:

y=-\frac{5}{3}x-2

Step-by-step explanation:

The first line has a slope of -5/3 found using the points in the slope formula.

m=\frac{y_2-y_1}{x_2-x_1} =\frac{-9--4}{0--3}=\frac{-9+4}{0+3}=\frac{-5}{3}

Parallel lines have the same slope. So -5/3 is the slope of the second line. Write its equation using the point slope form y-y_1=m(x-x_1).

y--7=-\frac{5}{3}(x-3)\\y+7 = -\frac{5}{3}(x-3)\\y=-\frac{5}{3}x + 5 -7\\y=-\frac{5}{3}x-2

What is the area of a circle with a radius of 35 inches<br> in2<br> (Use 3.14 for Pi.)
Amanda [17]

Answer: area= 3846.5 inch^2

Step-by-step explanation:

Area of circle = πr^2

Where r is the radius and pi is 3.14

So, we get..

3.14 x (35)^2

= 3.14 x 35 x 35

= 3.14 x 1225

= 3846.5 inch^ 2
