Novosadov [1.4K]

Domain is the x-values.

Scenarios where positive integers are appropriately used for the domain of the function:

The function c(p) represents The cost for P people to attend the movies. (number of people can either be 0 going upwards)

the function m(t) represents the miles driven over T hours (hours always start with 1.)

the function t(m) represents the average high temperature for a given number of months (number of months always start with 1)

the function p(w) represents the prophet of a farmer who sells whole watermelons (count of whole watermelon starts with 1)

the function h(n) represents the number of person-hours it takes to assemble n engines in a factory (number of engines always start with 1)

An isosceles triangle has a base of 4 and a height of x+3. If the area is 10, what is the value of x?

kicyunya [14]

The area of a isosceles triangle:
S=(bh)/2, where b is for base (=4) and h is for height (=x+3)
We get the equation:
10=(4*(x+3))/2
10=(4x+12)/2
4x+12=20
4x=8
x=2

Standard deviation of 300, 785, 670, 187, 760, 724

White raven [17]

STEP 1

Mean = $\frac{300+785+670+187+760+724}{6} = \frac{3426}{6}=571$

STEP 2

Subtract the mean from each data value then square the answer
$300-571=-271$ ⇒ $(-271)^{2} =73441$
$785-571=214$ ⇒ $(214)^{2}=45796$
$670-571=99$ ⇒ $(99)^{2}=9801$
$187-571=-384$ ⇒ $(-384)^{2} =147456$
$760-571=189$ ⇒ $189^{2}=35721$
$724-571=153$ ⇒ $153^{2} =23409$

STEP 3

Add the squared answers in STEP 2 then find the mean

$\frac{73441+45796+9801+147456+35721+23409}{6}= \frac{335624}{6}=55937.3$

STEP 4

Square root the answer in STEP 3
$\sqrt{55937.3} =236.5$

Standard deviation is 236.5
