Based on the number of people who are engineers and those who are chemical engineers, the percentage who are chemical engineers is 2.01%

To find the percentage of something out of the total number, the formula is:

= Number of selected variables / Total number of variables x 100%

The selected variable here is chemical engineers so the percentage of chemical engineers out of the total number of engineers is:

= Number of chemical engineers / Total number of engineers x 100%

= 27,860 / 1,326,800 x 100%

= 2.01%

Answer:

domain: all x-values

Step-by-step explanation:

Answer:

Domain: { -5, -1, 1, 3, 4}
Range: { -2, 1, 5}

Step-by-step explanation:
Domain = X-Values

Range = Y-Values

Every possible X-Value is the domain, and likewise with the Range.

Meaning if it was a line that went on forever through Y-1 the the Domain would be X = {-[infinity], +[infinity]} and the range would be Y = {1}

Step-by-step explanation:

The required two odd numbers are 3 and 5.

We have to determine,  It is a factor of 30 and a multiple of 3 what are 2 numbers.

To obtain the factor of 30 and 2 numbers is calculated in the following steps.

The Factors of 30 are,

30 = 2 , 3 , 5 ,

And multiply the terms by 2,

After multiply by 2 all the term become even.

Then,

The 2 odd numbers are: 3, 5

Hence, The required two odd numbers are 3 and 5.

By solving the simultaneous equation value of x = -5, -2 and y = 1, 4.

How to solve simultaneous equation?
1. Use the elimination method to get rid of one of the variables.

2. Find the value of one variable.

3. Find the value of the remaining variables using substitution.

Given that,

y = [tex]x[/tex]+3

y = [tex]x^{2} +5x-2[/tex]

First both equation are equal

[tex]x+3 = x^{2} +5x-2\\x^{2} +4x-5 =0\\x^{2} +5x-x-5=0\\x(x+5)-1(x+5)=0\\x=1, -5[/tex]

Then, substitute the value of x in y =x+3

y = x+3

at x= -5

y= -2

at x= 1

y = 1+3

y = 4

Hence, By solving the simultaneous equation value of x = -5, -2 and y = 1, 4.

The probability that the ace of spades will be revealed before any face card (the jack, queen, or king) is 0.0769.

Probability refers to potential.This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability has been applied into mathematics to predict the likelihood of different events.

The likelihood is based on the range of potential outcomes. the total number of possible outcomes. As an illustration, since there is only one way to get a head and a total of two possible results, the likelihood of flipping a coin and getting heads is one in two. a tail or a head.

According to given data;

Let's look at the first few probabilities; we're going to do this in reverse order, in order to find a pattern:

P(O,O,O,AS)=39/52)*(38/51)*(37/50)*(1/49)

                  =(39*38*37/3!)/(52*51*50/3!)*1/49

P(O,O,AS)=(39/3)(52/3)×1/49

        but we know that;

(n/2)=n(n-1)/2!

P,(O,O,AS) =(39/2)/(52/2)  *1/50

P(AS)=(39/0)/(52/0) *(1/52)

The volume of the cereal box is 144 square inches its width is two inches, its length is six inches and its height is 12 inches.

The top, bottom, and lateral faces of a rectangular prism are all rectangles, and all the pairs of opposing faces are congruent. A rectangular prism is a three-dimensional structure with six faces.

The rectangular prism's base area is equal to lw (using the area of a rectangle formula)

The height of the rectangle prism is equal to h.

Thus, V = lw ×h = lwh is the formula for the rectangular prism's volume.

Given,

width = 2 inches

length = 6 inches

height = 12 inches

The volume of a rectangular prism is simply length× width× height.

Volume = 6× 2× 12

= 144 square inches.

Answer:

x^2 + y^ = 36

Step-by-step explanation:

See attached worksheet.

Using an exponential function, it is found that:

a) During the first five days, the population of organism A grew by a factor of 2^5.

b) During the next three days, the population of organism B decayed by a factor 2^(-3).

c) The expression for the total change is of 2².

An exponential function is modeled according to the following rule:

[tex]y = ab^x[/tex]

In which:

For the first five days, the population doubles each day, hence the rate of change is of:

b = 2.

The growth factor will be of:

y = 2^5 = 32

During the next three days, the population cuts in half each day, hence the rate of change is of:

b = 0.5.

Then the decay factor is of:

y = (0.5)³ = (1/2)³ = 2^(-3).

Applying properties of exponents, over the entire period, the change in the population will be of:

2^5 x 2^(-3) = 2^(5 - 3) = 2².

As when we multiply two terms with the same base and different exponents, we keep the bases and add the exponents.

Answer: y+5=3/8*(x-4)

Step-by-step explanation: Find the slope using m = y2-y1/x2-x2 which is the change of y over change of x, so the slope is m=3/8. Use the slope 3/8, and a given point (4, -5) to substitute for x1 and y1 in point slope form y -y1 = m(x-x1). So y-(-5)=3/8*(x-(4)). Now we simplify the equation so it's y+5=3/8*(x-4).
