Kate and Stella both worked at the coffee shop today. Kate's total cups of coffee made is represented by f(x); and Stella's tota

SVETLANKA909090 [29]

Answer:

The function that represents the total cups of coffee they made today is $h(x)=9x-7$ .

Step-by-step explanation:

The given function are

$f(x)=6x-8$

$g(x)=3x+1$

Where, Kate's total cups of coffee made is represented by f(x) and Stella's total cups of coffee made is represented by g(x).

The total cups of coffee they made today is represented by the function

$h(x)=f(x)+g(x)$

Substitute the value of functions.

$h(x)=6x-8+3x+1$

Combine like terms.

$h(x)=(6x+3x)+(-8+1)$

$h(x)=9x-7$

Therefore the function that represents the total cups of coffee they made today is h(x)=9x-7.

Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are approximately normally

Anastasy [175]

Answer:

a) the required probability is 0.0013

b) the required probability is 0.0288

c) the required probability is 0.9759

Step-by-step explanation:

Given the data in the question;

let x be the thickness measurements

Given that X follows a Normal distribution with mean μ = 5.4

standard deviation σ = 0.8

then z = x-μ / σ = x-5.4 / 0.8 follows standard Normal

a) probability that the thickness is less than 3.0 mm

P( x<3 ) = P( x-5.4 / 0.8 < 3-5.4 / 0.8 ) = P( Z < -3.00 ) = 0.0013

Therefore, the required probability is 0.0013

b) the thickness is more than 7.0 mm

P( x>7 ) = P( x-5.4 / 0.8 > 7-5.4 / 0.8 ) = P( Z > 2.00)

= 1 - P( Z ≤ 2)

= 1 - 0.9772

= 0.0288

Therefore, the required probability is 0.0288

c) the thickness is between 3.0 mm and 7.0 mm

P(3< x<7 ) = P( x<7) - P(x<3)

= P( x-5.4 / 0.8 > 7-5.4 / 0.8 ) - P( x-5.4 / 0.8 < 3-5.4 / 0.8 )

= P( Z< 2 ) - P( Z < -3)

= 0.9772 - 0.0013

= 0.9759

Therefore, the required probability is 0.9759

What are the coordinates of the intersection of the graphs of 3x - y^2 = 12 and y = -3

inessss [21]

Answer:

(7,-3)

Step-by-step explanation:

y = -3

substitute in the first equation

3x - y^2 = 12

3x - (-3)^2 = 12

3x - 9 = 12

3x = 12 + 9

3x = 21

x = 7

coordinates of intersection (7,-3)
