The statement "y varies directly as x," means that when x increases, y increases by the same factor. In other words, y and x always have the same ratio: y/x =K

it can be written as ---> y=kx

then put in the values to get a common ratio
k= y/x
k1= 11/7
k2= 13/8

therefore, there's no common ratio in the given table

Maru [420]

Answer:

(12, 487)

Step-by-step explanation:

y = 3.7x + 442 ----› Eqn. 1

y = 14.4x + 312 ----› Eqn. 2

Substitute y = (3.7x + 442) into eqn. 2.

y = 14.4x + 312 ----› Eqn. 2

3.7x + 442 = 14.4x + 312

Collect like terms

3.7x - 14.4x = -442 + 312

-10.7x = -130

Divide both sides by -10.7

x = 12.1495327

Substitute x = 12.1495327 into eqn. 1.

y = 3.7x + 442 ----› Eqn. 1

y = 3.7(12.1495327) + 442

y = 486.953271

The solution to the system is rounded to the nearest integer:

Looking at the triangle we see the angles:

58, x

We also see a right angle, therefore you now have:

90, 58, 0

All three angles of a triangle should have a total of 180 degrees, so we add the known angles and subtract the total from 180.

90 + 58 = 148

180 - 148 = 32

Therefore, x = 32 or C

Question 37 (1 point)
o-na [289]

Answer:

The probability is:

P =\frac{1}{16}

Step-by-step explanation:

Keep in mind that the probability of getting a head is always the same for each

p = 0.5

Therefore the probability of not having a head is:

q = 1-p = 0.5\\q = 0.5

So if we throw the coin 4 times the probability P of not getting any head is:

P = q * q * q * q\\\\P = q ^ 4\\\\P = 0.5 ^ 4\\\\

P =\frac{1}{16}
