Answer:

Step-by-step explanation:

Answer:  Choice C

Equation is |x − 20| = 0.45

The min is x = 19.55

=====================================================

Explanation:

fl oz = fluid ounces

x = volume of the drink in fl oz

The expression |x-20| represents how far x is from the target of 20 fl oz. We use absolute value to ensure the result is never negative. It might help to draw out a number line.

Two examples:

If x = 22 then |x-20| = |22-20| = |2| = 2 which shows that 22 is 2 units away from 20 on the number line.

If x = 17 then |x-20| = |17-20| = |-3| = 3 which shows that 17 is 3 units away from 20 on the number line.

We want this difference to be within 0.45 fl oz, i.e. we want |x-20| to either equal 0.45 or be smaller than it.

If we only cared about the min and max, then we set |x-20| equal to 0.45 to generate the equation |x − 20| = 0.45

----------------

Solve this equation to find the min and max.

|x - 20| = 0.45

x-20 = 0.45 or x-20 = -0.45

x = 0.45+20 or x = -0.45+20

x = 20.45 or x = 19.55

The min is 19.55 fl oz and the max is 20.45 fl oz.

Phrased another way: the x values span from 19.55 to 20.45, inclusive of both endpoints. We could write  as a compact way to describe what values x could be.

7. The hexagon GIKMPR is regular. The dashed line segments form 30 degree angles. what is the image of oh after a rotation of 18
velikii [3]

Answer:

The image of OH is ON.

Step-by-step explanation:

Te figure GIKMPR is a regular hexagon. The number of vertices of a regular hexagon is 6. The central angle between any two consecutive vertices is 60 degree.

The dashed line segments form 30 degree angles.

If we rotate the hexagon 180 degree about O, then the each point shifts to 6th place from its original place.

Since we rotate the hexagon 180 degree about O, so the image and preimage lies on a straight line. Because a straight line make angle of 180 degree.

The line OH and ON lies on a straight line therefore the image of OH is ON.

I need help on this please help!
Licemer1 [7]

Answer:

(b)0.56

(c)0.38

Step-by-step explanation:

(a)

P(Ben Pass) =0.8

Therefore: P(Ben fails)=1-0.8 =0.2

P(Tom Pass) =0.7

Therefore: P(Tom fails)=1-0.7 =0.3

See attached for the completed tree diagram

(b)Probability that both will pass

P(both will pass)=P(Ben pass and Tom pass)

=P(Ben pass) X P(Tom pass)

=0.8 X 0.7

=0.56

(c)The probability that only one of them will pass

Since either Tom or Ben can pass, we have:

P(only one of them will pass)

=P(Ben pass and Tom fails OR Ben Fails and Tom Pass)

=P(Ben pass and Tom fails)+P(Ben Fails and Tom Pass)

=(0.8 X 0.3) + (0.2 X 0.7)

=0.24 + 0.14

=0.38

If f(x) =3^x+10 and g(x) =4x -2 find (f+g)(x)
Valentin [98]

Answer:

(f+g)(x)=3^x+4x+8

if f(x)=3^x+10 and g(x)=4x-2.

Step-by-step explanation:

We are given f(x)=3^x+10 and g(x)=4x-2.

We are asked to find (f+g)(x).

(f+g)(x) means f(x)+g(x)

(f+g)(x)=(3^x+10)+(4x-2)

You only have one pair of like terms, that is the constants.

(f+g)(x)=3^x+4x+10-2

(f+g)(x)=3^x+4x+8
