What are the coordinates of the vertices of the polygon in the graph that are in Quadrant I? Question 7 options: A) (–3,–4) B) (1,1), (2,2), (2,5), (5,5) C) (2,–3), (3,–4), (5,–4) D) (–4,2), (–2,5)

Answers

Answer 1

Answer:

Answer:

Answer B (1,1), (2,2), (2,5), (5,5)

Step-by-step explanation:

Notice that although the image is not shown, of the given answers, the only points that have coordinates that belong to Quadrant I , are those that show oosittive number for both coordinates (for x and for y). That is the only possible solution is:

answer B) : (1,1), (2,2), (2,5), (5,5)

A factory received a shipment of 10 generators, and the vendor who sold the items knows there are 4 generators in the shipment that are defective. Before the receiving foreman accepts the delivery, he samples the shipment, and if too many of the generators in the sample are defective, he will refuse the shipment. Give answer as a decimal to three decimal places.

Complete Question

A factory received a shipment of 10 generators and the vendor who sold the items knows there are 4 generators in the shipment that are defective. Before the receiving foreman accepts the delivery, he samples the shipment, and if too many of the generators in the sample are defective, he will refuse the shipment. Give answer as a decimal to three decimal places.

(A) If a sample of 4 generators is selected, find the probability that all in the sample are defective.

(B) If a sample of 4 generators is selected, find the probability that none in the sample is defective.

Solution

A) This is a binomial distribution problem

Binomial distribution function is represented by

P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ

n = total number of sample spaces = number of generators to be picked = 4

x = Number of successes required = number of defective generators required = 4

p = probability of success = probability that a randomly selected generator is defective = (4/10) = 0.40

q = probability of failure = probability that a randomly selected generator is NOT defective = 1 - p = 1 - 0.40 = 0.60

P(X = 4) = ⁴C₄ (0.40)⁴ (0.6)⁴⁻⁴ = 0.0256 = 0.026 to 3 d.p.

B) n = total number of sample spaces = number of generators to be picked = 4

x = Number of successes required = number of defective generators required = 0

p = probability of success = probability that a randomly selected generator is defective = (4/10) = 0.40

q = probability of failure = probability that a randomly selected generator is NOT defective = 1 - p = 1 - 0.40 = 0.60

P(X = 0) = ⁴C₀ (0.40)⁰ (0.6)⁴⁻⁰ = 0.1296 = 0.130 to 3 d.p.

G(x) = 2x − 1 h(x) = 1 − g(x) The functions g and h are defined above. What is the value of h(0)?

Answers

The value of $h(0)$ is 2.

It is given that,

$g(x)=2x-1$
$h(x)=1-g(x)$

Explanation:

We have,

$h(x)=1-g(x)$

$h(x)=1-(2x-1)$

$h(x)=1-2x+1$

$h(x)=2-2x$

Substitute $x=0$ in the above function.

$h(0)=2-2(0)$

$h(0)=2-0$

$h(0)=2$

Thus, the value of $h(0)$ is 2.

Answer:

h(0) is equal to 2.

Step-by-step explanation:

In order to find this, we first put 0 in for x in the g(x) equation.

g(x) = 2x - 1

g(0) = 2(0) - 1

g(0) = -1

Now that we have this, we can stick the answer for g(x) into the f(x) equation.

f(x) = 1 - g(x)

f(x) = 1 - -1

f(x) = 1 + 1

f(x) = 2

What is the x-and y-intercept of the graph 4x -5y =40??

Answers

Answer:

x-intercept = 10

y-intercept = -8

Step-by-step explanation:

$4x-5y=40$

To identify the y-intercept, we will need to format the equation in the form $y=mx+b$ . We can start by subtracting $4x$ from both sides of the equation:
