An electronics company can spend no more than $4,000 on raw materials for circuit boards. The raw materials cost $10 per ounce f

or copper and $20 per ounce for silver.
To summarize the situation, a worker writes the inequality:

10c + 20s ≤ 4,000, where c is the number of ounces of copper material and s is the number of ounces of silver material.

Which graph's shaded region shows the possible combinations of raw materials the company can buy?

OLga [1]

Answer:

probability that his sample will contain at least one damaged apple (P) = 0.7215

Step-by-step explanation:

Given:

Probability of damaged apples (p) = 12% = 0.12

number of samples (n) = 10

Consider,

x- number of apples damaged.

Using Binomial distribution formula:

P(x) = (nCx) (P)^x (1-p)^(n-x)

To find the probability that his sample will contain at least one damaged apple:

P(x≥1) = 1 - P(x<1)

          = 1 - P(x=0)

          = 1 - 10C_0 (0.12)^0 ( 1-0.12)^(10)

P(x≥1)  = 0.7215

Rewrite the following equation in slope-intercept form. 14x + 15y = 11 Write your answer using integers, proper fractions, and i
Goshia [24]
Answer:
y = (-14/15) x + (11/15)

Explanation:
The slope-intercept form has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
14x + 15y = 11

To put this in slope-intercept form, we will need to isolate the y as follows:
14x + 15y = 11
15y = -14x + 11
y = (-14/15) x + (11/15)
were:
m is the slope = -14/15
c is the y-intercept = 11/15

Hope this helps :)
