Answer:

138 cm^2 = Area . 54 cm = Perimeter

Step-by-step explanation:

Find the area of the triangle- b * h = A

8 * 6 = A

48/2 = A

24 = A

Find the area of rectangle- l * w = A

16 * 7 = A

112 = A

Add the areas together. 24 + 112 = 136 cm^2

Perimeter is adding up all the sides. s + s + s + s + s

16 + 7 + 8 + 10 + 13 = 54 cm

Answer:

perimeter of this figure is = 54 cm

and area of traingle is = 1/2*base *height

so = 1/2*8*6

=. 24cm*cm

and area of rectangle = length * breadth 

 area = 112cm*cm

so total area = 112+ 24 = 136cm*cm 

hope it helps and your day will full of happiness

Binomial distribution can be used because the situation satisfies all the following conditions:1. Number of trials is known and remains constant (n)2. Each trial is Bernoulli (i.e. exactly two possible outcomes) (success/failure)3. Probability is known and remains constant throughout the trials (p)4. All trials are random and independent of the othersThe number of successes, x, is then given by $P(x)=C(n,x)p^x(1-p)^{n-x}$ where $C(n,x)=\frac{n!}{x!(n-x)!}$
Here we're given
p=0.10 [ success = defective ]
n=3

(a) x=0
$P(x)=C(n,x)p^x(1-p)^{n-x}$
$=C(3,0)0.1^0(1-0.1)^{3-0}$
$=1(1)(0.729)$
$=0.729$

(b) x=2
$P(x)=C(n,x)p^x(1-p)^{n-x}$
$=C(3,2)0.1^2(1-0.1)^{3-2}$
$=3(0.01)(0.9)$
$=0.027$

(c) x ≥ 2
$P(x)=\sum_{x=2}^3C(n,x)p^x(1-p)^{n-x}$
$=P(2)+P(3)$
$=C(n,2)p^2(1-p)^{n-2}+C(n,3)p^3(1-p)^{n-3}$
$=C(3,2)0.1^2(1-0.1)^{3-2}+C(3,3)0.1^3(1-0.1)^{3-3}$
$=3(0.01)(0.9)+1(0.001)1$
$=0.027+0.001$
$=0.028$

Solve the equation or formula for the indicated variable.

alex41 [277]

Subtract 3 both sides first. R-3=ts²

next, divide both sides by t, (R-3)/t=s²

finally, take the square root of both sides

√(R-3)/t = s. 2nd choice.

The graph of F(x) can be flipped over a certain line to produce the graph of its inverse. What is the equation of that line?

OlgaM077 [116]

The correct answer is: 
y=x.

Explanation: 
In order to find the inverse of a function, we first switch x and y; then we isolate y. When we do this, we are saying that x and y equal the same thing, or y=x.
