Answer:

x = 2

Step-by-step explanation:

2(3х + 5) = 22

Divide both sides by 2.

3x + 5 = 11

Subtract 5 from both sides.

3x = 6

Divide both sides by 3.

x = 2

(Essay Question 7 Points)
Irina18 [472]

Well I don't know.
Let's think about it:

-- There are 6 possibilities for each role.
    So 36 possibilities for 2 rolls.
    Doesn't take us anywhere.

New direction:
-- If the first roll is odd, then you need another odd on the second one.
-- If the first roll is even, then you need another even on the second one.
This may be the key, right here !

-- The die has 3 odds and 3 evens.

-- Probability of an odd followed by another odd = (1/2) x (1/2) = 1/4
-- Probability of an even followed by another even = (1/2) x (1/2) = 1/4

I'm sure this is it.  I'm a little shaky on how to combine those 2 probs.

Ah hah ! 
Try this:

Probability of either 1 sequence or the other one is (1/4) + (1/4) = 1/2 .

That means ... Regardless of what the first roll is, the probability of
the second roll matching it in oddness or evenness is 1/2 .

So the probability of 2 rolls that sum to an even number is 1/2 = 50% .

Is this reasonable, or sleazy ?

Contact [7]

Answer:

Step-by-step explanation:

Given that latitude and longitude describe locations on the Earth with respect to the equator and prime meridian.

Latitude High Temp

("N)  

 

12 53

 

16 41

 

30 67

 

36 63

 

32 70

 

11 58

 

10 61

 

33 67

 

30 72

 

 

Slope 0.732

Int -21.56266667

Regression line is y = 0.732x-21.563 where x represents the latitude and y high temperature

Since slope = 0.732, we get temp increases by 0.8 degree for 1 degree increasenorth in latitude

Hence option c is right

Pyramid A is a square pyramid with a base side length of 14 inches and a height of 6 inches. Pyramid B has a volume of 3,136 cub
mash [69]

Answer:

12.5%    Step 1  to find volume of Pyramid A  Step 2 is find percentage through division then multiplication of 100  

Step-by-step explanation:   Length of one side of the base (a) = 14 in

Height of square pyramid (h) = 6 in

Using the square pyramid volume formula,

Volume = 1/3 x a^2 x h

Volume = 1/3 x 14^2 x 6

Volume = 392 in3

The volume Pyramid A is 392 cubic inches.

Pyramid A has a volume = 392 cubic units     Pyramid B has a volume of 3,136 cubic inches.    to find percentage 392 of 3136 we divide then * 100   To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator...  = (392/3136 ) x 100% = 12.5%   Proof is  (12.5 * 3136 ) / 100 = 392
