What is equivalent to<br> -9(x - 4 ) - 6x

Lapatulllka [165]

The answer would be -15x+36. To solve this equation, you would first use distributive property and distribute the -9 to the values inside the parentheses (or multiply them). So, you would multiply -9 and x and -9 and -4 to get -9x+36-6x. Then, you combine like terms, which are -9x and -6x to get -15x. You can't simplify any further without knowing the value of x. Hope this helps!

An electronics company has two production facilities, denoted A and B. During an average week, facility A produces 2000 computer

kozerog [31]

Answer:

8 weeks of production from A and 4 weeks of production of B required to produce 28,000 monitors and 132,000 televisions.

Step-by-step explanation:

Let the number of weeks of production for team A be x and for team B be y.

In a week, facility A produces 2,000 computer monitors.

In a week ,facility A produces 3,000 computer monitors.

Total monitors to be produced = 28,000

$2000x+3000y=28,000$

$2x+3y=28$ ..[1]

In a week, facility A produces 10,000 flat panel televisions.

In a week ,facility A produces 13,000 flat panel televisions.

Total flat panel televisions to be produced = 132,000

$10,000x+13,000y=132,000$

$10x+13y=132$ ..[2]

Solving equation [1] and [2] by eliminationg method.

5 × [1] + (-1) × [2]

$10x+15y=140$

$-10x-13y=-132$

y = 4

$x = \frac{28-3\times 4}{2}=\frac{16}{2}=8$

8 weeks of production from A and 4 weeks of production of B required to produce 28,000 monitors and 132,000 televisions.

The difference in the x-coordinates of two points is 3, and the difference in the y-coordinates of the two points is 6. Wha

Yanka [14]

Answer:

to find the slope you get the rise which is the difference between the y coordinates over the run which is the difference between the x coordinates. so 6/3=2

Almost all medical schools in the United States require students to take the Medical College Admission Test (MCAT). To estimate

yKpoI14uk [10]

Answer:

a) 0.5588

b) 0.9984

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 24

Standard Deviation, σ = 6.4

We are given that the distribution of score is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P(score between 20 and 30)

$P(20 \leq x \leq 30) = P(\displaystyle\frac{20 - 24}{6.4} \leq z \leq \displaystyle\frac{30-24}{6.4}) = P(-0.62 \leq z \leq 0.94)\\\\= P(z \leq 0.94) - P(z < -0.62)\\= 0.8264 - 0.2676 = 0.5588 = 55.88\%$

$P(20 \leq x \leq 30) = 55.88\%$

b) Sampling distribution

Sample size, n = 22

The sample will follow a normal distribution with mean 24 and standard deviation,

$s = \dfrac{\sigma}{\sqrt{n}} = \dfrac{6.4}{\sqrt{22}} =1.36$

c) P(mean score of sample is between 20 and 30)

$P(20 \leq x \leq 30) = P(\displaystyle\frac{20 - 24}{1.36} \leq z \leq \displaystyle\frac{30-24}{1.36}) = P(-2.94 \leq z \leq 4.41)\\\\= P(z \leq 4.41) - P(z < -2.94)\\= 1 - 0.0016 = 0.9984 = 99.84\%$

$P(20 \leq x \leq 30) =99.84\%$
