how did you find the domain and range of function using ordered pairs mapping diagram,graph,table and equation/rule? Explain

The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.

Answer:

A mapping diagram consists of two parallel columns. The first column represents the domain of a function f , and the other column for its range. Lines or arrows are drawn from domain to range, to represent the relation between any two elements.

F(x)=-2x^2+3x+7 find f(3)

Inessa [10]

Answer:

f(3) = -2

Step-by-step explanation:

Given the f(x) = -2x² + 3x + 7, to find f(3):

We can substitute 3 as the value of x in the given function:

f(x) = -2x² + 3x + 7

f(3) = -2(3)² + 3(3) + 7

f(3) = -2(9) + 9 + 7

f(3) = -18 + 9 + 7

f(3) = -9 + 7

f(3) = -2

Therefore, f(3) = - 2.

Scores on a certain intelligence test for children between ages 13 and 15 years are approximately normally distributed with μ=10

Tju [1.3M]

Answer: 0.8238

Step-by-step explanation:

Given : Scores on a certain intelligence test for children between ages 13 and 15 years are approximately normally distributed with $\mu=106$ and $\sigma=15$ .

Let x denotes the scores on a certain intelligence test for children between ages 13 and 15 years.

Then, the proportion of children aged 13 to 15 years old have scores on this test above 92 will be :-

$P(x>92)=1-P(x\leq92)\\\\=1-P(\dfrac{x-\mu}{\sigma}\leq\dfrac{92-106}{15})\\\\=1-P(z\leq })\\\\=1-P(z\leq-0.93)=1-(1-P(z\leq0.93))\ \ [\because\ P(Z\leq -z)=1-P(Z\leq z)]\\\\=P(z\leq0.93)=0.8238\ \ [\text{By using z-value table.}]$

Hence, the proportion of children aged 13 to 15 years old have scores on this test above 92 = 0.8238

I want to install carpet in my living room, which is 200 inches long and 50 ft wide. The carpet is sold for 5000 naira per yard2

inn [45]

Answer:

462962.96 naira

Step-by-step explanation:

This problem is complicated by the use of two different units. I chose to use inches for the dimensions of the carpet.

200 in long

50 ft wide = 50 x 12 = 600 in.

Area = 200 x 600 = 120000 in^2

A square yard is a square 36 in. x 36 in. = 1296 in^2

Divide 120000 by 1296 to find out how many square yards of carpet you'll need.

120000 / 1296 = 92.59

Multiply by 5000 naira/yd^2 = 462962.96
