The sum of the ages of pam,dion, and their three children, in years, is 5x - 99. where x is dion's age. pam is five years younger than dion. what is the usm of the ages of their children?

Answer:

Step-by-step explanation:

COP = Constant of Proportionality. • y varies directly to x. > If 10 miles varies directly to 5 minutes,. – then 10 = y and 5 = x. • Unit Rate (1, r). > (x, y).

If the p-value is less than or equal to the selected significance level, the null hypothesis is rejected; otherwise, it is not. In other words, if p, reject[tex]H_{0}[/tex]; if p>, do not reject [tex]H_{0}[/tex].

In null hypothesis testing, this criterion, also known as (alpha), is frequently set to 05. If there is less than a 5% chance that the null hypothesis would be accepted and a result as spectacular as the effects that result would occur, the null hypothesis is rejected. When this happens, the result is said to be statistically significant.

The null hypothesis would be rejected if a statistical test was conducted with a threshold of relevance = 0.1, 0.05, & 0.01.

If the P value is smaller than alpha, the preset level of statistical significance, the alternative hypothesis is considered instead of the null hypothesis.

The actual roots ordered from least to greatest is -45, - 15, -9, - 5, - 3, - 1, +1, +3, +5, +9, +15, and +45

Rational roots are roots of a quadratic equation which can be expressed as a ratio or are elements of rational numbers.

Since we have that the possible rational roots are  ±1, ±3, ±5, ±9, ±15, and ±45.

We list the actual roots as follows

+1, -1, +3, -3, +5, -5, +9, -9, +15, - 15, +45 and -45

Since we require the actual roots from least to greatest knowing that the largest negative number is the least and tha largest positive number is the greatest, rearranging, we have

-45, - 15, -9, - 5, - 3, - 1, +1, +3, +5, +9, +15, and +45

We have to find the number of ways voters could rank their first 5 choices.

Permutation;

An arrangement of items in a specific order is referred to as a permutation. Here, the components of sets are arranged in a linear or sequential order.

Here we have to use permutation formula;-

The absolute equation in the graph is f(x) = |x - 3| + 5

From the question, we can see that the lines on the graph has a sharp v-shape

Graphs that have this form are absolute value graphs

The general form of an absolute value equation is expressed as

y = |x - h| + k

From the above form, we have

Vertex = (h, k)

By definition, the vertex of a function is either the maximum point or the minimum point

On the given graph, the minimum point is (3, 5)

So, we have the following representation

(h, k) = (3, 5)

Substitute (h, k) = (3, 5) in the above equation

So, we have:

y = |x - 3| + 5

Hence, the function represented by the graph has an equation of f(x) = |x - 3| + 5

It is possible to determine a line's direction and steepness by looking at its slope.

Finding the slope between lines inside a coordinate plane can aid in anticipating if the lines are perpendicular, parallel, or none at all without physically using a compass.

A line's basic formula in gradient intercept form is y=mx + b. It is rewritable in point-slope form.

When y-b is equal to m(x-0), the location is the y-intercept (0,b).

The basic equation for a line with m=slope and (k,h) a position on the line is y-h=m(x-k).

By determining y and adding constant variables, the equation can be recast in slope-intercept form.

Dimensions of the area enclosed is l = 800 ,b = 800 and the maximum area = 6,40,000 square yards.

Given:

Liana has 3200 yards of fencing to enclose a rectangular area.

Let l and b be the length and breadth.

we know that:

perimeter of rectangle = 2(l+b)

2l + 2b = 3200

l+b = 1600

b = 1600 - l

Area of rectangle A = lb

= l*1600-l

= 1600 l - l^2

Apply derivative:

dA/dl = 1600 - 2l

1600 - 2l = 0

1600 = 2l

l = 1600/2

l = 800

l+b = 1600

A) The equation is 22 + (d * 1/2) = 30

B) The plant that still have to grow 8 cm more

C) d = 16 days, d represents the number of days

Step-by-step explanation:

Given:

Initial height (basil plant at buying) = 22cm

Plant grows on everyday = 1/2cm

A) Given:

Total  height (to be grown) = 30 cm.

The equation is,

Initial height+ ( number of days * plant grows on everyday) =  Total height

22 + (d * 1/2) = 30  →  equation 1

B) The plant that still have to grow = Total height - Initial height

= 30 - 22

= 8 cm

C) Solving the value d using equation 1:

22 = 30 - (d * 1/2)
