Answer:

The total surface area of this square pyramid is 297\ mm^{2}

Step-by-step explanation:

we know that

The surface area of a square pyramid is equal to

SA=b^{2} +4[\frac{1}{2}(b)(h)]

we have

b=9\ mm ----> the length side of the square base

h=12\ mm ----> the height of the triangular faces

substitute the values

SA=9^{2} +4[\frac{1}{2}(9)(12)]=297\ mm^{2}

3. We can see that
1+100=101
2+99=101
3+98=101
.................
and so on
From 1 to 100, there are 50 pairs that has the sum is 101
Z=101×50=5050
4. We can see that
1-2=-1
3-4=-1
5-6=-1
...........
and so on
There are 10 pairs that has sum is -1
Z= 10×(-1)=-10

You are dealt one card from a​ 52-card deck. find the probability that you are not dealt a two
Rina8888 [55]

There are 52 cards in a deck.

First we find the probability of drawing a 2

There are 4 cards that shows 2

Probability of drawing a 2 card fro 52 cards = 4 / 52

We know that P( not A) = 1 - P(A)

So the probability (not dealt a 2) = 1 - probability (dealt a 2)

= 1 - 4/52

= (52 - 4)/ 52 = 48/52

Now we simplify the fraction

48/ 52 = 12/13

Hence, the probability( not dealt a 2) = 12/13
