Answer:

P(X ≥ 2) = 0.5967

Step-by-step explanation:

Using binomial probability distribution formula;

P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)

two percent of a product are defective. Thus; p = 0.02

a lot of 100 items are ordered. Thus, n = 100

Probability that there are no defective items is;

P(X = 0) = C(100, 0) × 0.02^(0) × (1 - 0.02)^(100 - 0)

P(X = 0) = 0.98^(100) = 0.1326

the probability that there are at least two defective items will be;

P(X ≥ 2) = 1 - P(X < 2)

Now,

P(X < 2) = P(X = 0) + P(X = 1)

P(X = 1) = C(100, 1) × 0.02^(1) × (1 - 0.02)^(100 - 1)

P(X = 1) = 100 × 0.02 × 0.98^(99) = 0.2707

Thus;

P(X < 2) = 0.1326 + 0.2707

P(X < 2) = 0.4033

P(X ≥ 2) = 1 - 0.4033

P(X ≥ 2) = 0.5967

A line with a slope of 4 passes through the point (2, 1). What is the equation of this line?
olasank [31]

Answer:

point slope form: y - 1 = 4 (x -2)

slope intercept form: y = 4x -7

Step-by-step explanation:

If you want it in point slope form it would be: y - 1 = 4 (x -2)

but if you want it in slope intercept form, you solve this equation

y -1 = 4 (x-2)

y-1 = 4x -8

 +1          +1

y = 4x -7 in slope intercept form

Divide the following polynomials, then place the answer in the proper location on the grid. Write answer in descending powers of
Varvara68 [4.7K]
Let's rewrite the given expression correctly:
 (2y3 + 3y2 - 4y - 5) / (y + 1)
 Dividing the expression between y + 1 we have:
 2y2 + y - 5
 We can check the result:
 (2y2 + y - 5) * (y + 1)
 = (2y3 + y2 - 5y + 2y2 + y - 5)
 = (2y3 + 3y2 - 4y - 5)
 Division OK.
 Answer:
 
The result of the division is:
 
2y2 + y - 5

The high temperature was 92 degrees fahrenheit this was 24 degrees fahrenheit higher than the overnight low temperature write an
motikmotik
We let x be the low temperature (in degrees Fahrenheit). A temperature that is 24 degrees Fahrenheit higher than this is 92. The equation that would best represent the scenario is,
                                      92 = x + 24
The value of x from the equation is 68. Therefore, the low temperature is 68 degrees Fahrenheit.
