What is the Slope of 7x+4y=20

yKpoI14uk [10]

Answer:

slope = $\frac{-7}{4}$

Explanation:

The general form of the linear line is:

y = mx + c

where:

m is the slope

c is the y-intercept

The given equation is:

7x + 4y = 20

We will start by putting the equation in the general form:

7x + 4y = 20

4y = -7x + 20

$\frac{4y}{4} = \frac{-7x}{4} + \frac{20}{4}$

y = $\frac{-7}{4} x + 5$

Now, comparing our equation with the general form, we would find that:

m = slope = $\frac{-7}{4}$

c = y-intercept = 5

Hope this helps :)

The assistant manager of a surf shop estimates that 65% of customers will make a purchase. Part A: How many customers should a s

Ivan

Answer:

A) 2

B) 0.239

Step-by-step explanation:

Part A) Expected value of a binomial distribution is the number of trials times the probability of success.

X = np

Given X = 1 and p = 0.65:

1 = 0.65n

n = 1.54

Rounding up, a salesperson should expect 2 customers until he finds a customer that makes a purchase.

Part B) Use binomial probability.

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

Given n = 3, r = 1, p = 0.65, q = 0.35.

P = ₃C₁ 0.65¹ 0.35³⁻¹

P ≈ 0.239

Or, using binompdf function in a calculator:

binompdf(n, p, r)

= binompdf(3, 0.65, 1)

≈ 0.239

7. A machine produces memory sticks of varying lengths, distributed uniformly between 3mm and 13 mm. Memory sticks longer than 1

Mars2501 [29]

Answer:

The proportion of memory sticks that will be scrapped is 0.3 = 30%.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

$P(X < x) = \frac{x - a}{b - a}$

The probability of finding a value between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The probability of finding a value above x is:

$P(X > x) = \frac{b - x}{b - a}$

Distributed uniformly between 3mm and 13 mm.

This means that $a = 3, b = 13$

Calculate the proportion of memory sticks that will be scrapped:

$P(X > 10) = \frac{13 - 10}{13 - 3} = \frac{3}{10} = 0.3$

The proportion of memory sticks that will be scrapped is 0.3 = 30%.
