A manufacturing company hired 30 new employees. This hiring increased the company’s total workforce by 5%. How many employees no
Setler79 [48]

We can solve this problem by using the formula:

1 + fractional increase = (original employees + new employees) / original employees

Lets say,

x = original employees

Therefore substituting the known values:

1 + 0.05 = (x + 30) / x

1.05 x = x + 30

0.05 x = 30

x = 600

Therefore the number of employees working now is:

<span>x +  30</span>

<span>= 630 employees</span>

A baker blends 600 raisins and 400 chocolate chips into a dough mix and, from this, makes 500 cookies. (a) Find the probability
Nina [5.8K]

Answer:

a) P(X = 0) for raisins = 0.33287

b) P(X = 2) for chocolate chips = 0.14379

c) P(X ≥ 2) for both bits = 0.59399

Step-by-step explanation:

The average amount of raisin per cookie is 600/500 = 1.2

The average amount of chocolate chips per cookie = 400/500 = 0.8

a) Using Poisson's distribution function

P(X = x) = (e^-λ)(λˣ)/x!

For raisin, Mean = λ = 1.1

x = 0

P(X = 0) = (e⁻¹•¹)(1.1⁰)/(0!) = 0.33287

b) Using Poisson's distribution function

P(X = x) = (e^-λ)(λˣ)/x!

For chocolate chips, Mean = λ = 0.8

x = 2

P(X = 2) = (e⁻⁰•⁸)(0.8²)/(2!) = 0.14379

c) the probability that a randomly chosen cookie will have at least two bits (raisins or chips) in it.

For this, the average number of bit in a raisin = (600+400)/500 = 2 bits per raisin.

P(X ≥ 2) = 1 - [P(X = 0) + P(X = 1)]

For P(X = 0)

P(X = x) = (e^-λ)(λˣ)/x!

Mean = λ = 2

x = 0

P(X = 0) = (e⁻²)(2⁰)/(0!) = 0.13534

For P(X = 1)

P(X = x) = (e^-λ)(λˣ)/x!

Mean = λ = 2

x = 1

P(X = 1) = (e⁻²)(2¹)/(1!) = 0.27067

P(X ≥ 2) = 1 - [P(X = 0) + P(X = 1)]

P(X ≥ 2) = 1 - (0.13534 + 0.27067) = 1 - 0.40601 = 0.59399

What is the length of BC¯¯¯¯¯ ? segment B C with point D between B and C. congruency markings at segment BD and at segement D C.
Arturiano [62]

Answer: segment BC = 36 units

Step-by-step explanation:

As per the given information, we have

B, C and D are three points such that

segment BC = segment BD + segment DC          ... (i)

And segment BD = segment DC                        ... (ii)

If segment BD = 18 units

Then, segment DC = 18 units   [From (ii)]

segment BC = 18 units +  18 units                [From (i)]

⇒segment BC = 36 units

Hence, length of \overline{BC} = 36 units

How do you differentiate linear equation from those equatipn which are not linear?​
dedylja [7]

Answer:

the x

Step-by-step explanation:

Looking at the x in an equation can reveal its shape. A linear graph can look like y=x, y=mx, y=mx+b (m being any number).

When you look at graphs that aren't linear, the x doesn't stand alone in the equation.

Parabolas have a y=x^2 equation. Cubic graphs are y=x^3. They have something attached to the x.

To see all the different kinds of equations and what their graphs look like you can search up "parent functions" and all the basic formulas show up.
