**Answer:**

1 / 14 tsp salt

(1 over 14)

**Step-by-step explanation:**

Let's set the scale factor as x.

So,

2 1/3 * x = 1

Divide both sides by 2 1/3, which is equal to 7/3

x = 1 / (7/3)

x = 3 / 7

So, amount of salt would be written as:

(1/6) * (3/7) =

(1/2) * (1/7) =

1 / 14 tsp salt

A) 0

b)-300

c)-450

(I think)

**Answer:**

13

**Step-by-step explanation:**

the absolute value is the opposite of its number, for example 6, the opposite of 6 is -6

hope this helps :)

and if it's wrong i am so sorry:(

**Answer:**

(1)+(2) Substitute Y from (2) in (1):

X2+(1−X)2=1X2+(1−X)2=1

...

2X(X−1)=02X(X−1)=0

Hense X= 0 or X = 1.

Answer:

0.6048

Step-by-step explanation:

Given the following :

Assume a normal distribution :

Mean (m) = 105

Standard deviation (sd) = 20

Find the probability that a randomly selected adult has an IQ between 88 and 122 .

Z = (x - m) / sd

For IQ score of 88:

Z = (88 - 105) / 20

Z = (-17) / 20

Z = - 0.85

For IQ score of 122:

Z = (122 - 105) / 20

Z = (17) / 20

Z = 0.85

P(-0.85<Z<0.85) = P(Z < 0.85) - P(Z < - 0.85)

P(-0.85<Z<0.85) = (0.8023 - 0.1977)

P(-0.85<Z<0.85) = 0.6048
