Answer:

$21 in^{2}$

Step-by-step explanation:

The square in the middle has a length and width of 3, so multiply. 9.

All of the triangles have a base of 3 and a height of 2. The area equation for triangles is

$A=bh\frac{1}{2}$

So base*height is 6. Divide that by 2 or multiply by 1/2.

You get 3. There are 4 triangles, so multiply that by 4. 12.

Add 12 and 9 together, and you get:

$21 in^{2}$

I hope this helps!

Kirima is building a wall for her snow fort. She first makes a firm base out of snow, and then piles uniformly sized blocks of s

MrMuchimi

Answer:

The correct option is;

0.4 represents the height of each block

Step-by-step explanation:

The information given are;

Kirima first builds a firm base of a given height

Kirima is building her wall using uniformly sized bricks

the height of the wall she is building depends on the number of blocks stacked to form the wall

Therefore, variable that depends on other variable, which is the dependent variable, y, is the height of the wall

The independent, which determines the value of the dependent variable is the number of blocks added, x

The gradient of the equation is the height of each block = 0.4

The y-intercept is the starting value, which is the firm base of dimension, 0.6

Therefore, 0.4 represents the height of each block.

Mensa is a high IQ society that admits people as members if they can score at the 98th percentile or above on certain standardiz

Mkey [24]

Answer:

Step-by-step explanation:

Let C represent a question answered correctly

G represent answer is given by guessing

K represent that individual is knowing the answer

Now given that

P(K)=p

So P(G)=1-p

Also if an individual know the answer then he will give the correct answer correctly hence P(C|K)=1

While if one is guessing then he will give correct option with 1/m probability that there are m options hence

P(C|G)=1/m

We have to find the P(K|C)

Now using Bayes theorem

P(K/C) = P(K)×P(C/K) = p×1

P(K)×P(C/K)+P(G)×P(C/G) p×1 +(1-p)×1/m

= mp

1+p(m-1)

Let

A represent that a person IQ level is more than 132

B represent IQ level is less than 132

C represent person lebelled as have IQ more then 132

Any person to be in that society needs to be in 98th percentile hence 98% peoples will be below that level hence

P(A)=0.02 P(B)=0.98

Also given than P(C|A)=0.95 while P(C|B)=0.001

We have to find P(B|C)

Now using Bayes theorem

P(B/C)= P(B)×P(C/B) = 0.98×0.001

P(B)×P(C/B)+P(A)×P(C/A) 0.98×0.001 +0.02×0.95

=0.045
