Samuel's average speed during his morning training is 0.41 miles/minute.

Here we have to find the average speed of Samuel. We can solve this problem by following a few steps.

According to the problem, Samuel was preparing for the triathlon. He did 3 activities every morning; ran for 30 minutes, covered 4.5 miles; swam for 20 minutes, covered 2.3 miles biked for 45 minutes, and covered 9 miles.

We have to recall the formula of average speed as,

average speed = total covered distance/ total time

The total distance which has been covered is,  

The total covered distance is, ( 4.5 + 2.3 + 9 ) = 36.5 miles.

The total time which has been spent is,

The total spent time is, (30+ 20+ 40) = 90 minutes.

Now, we can easily calculate the average speed. Which is (36.5/90) = .41 miles/minute.

The price of one candy box was $2.50 if the popcorn were of $3.20 and the total amount was $18.20.

The price of one candy box can be determined using an algebraic expression. An algebraic expression can be defined as one that consists of both numbers and letters.

As he ordered 6 boxes of candy and a bucket of popcorn and the popcorn was of $3.20 and the total was $18.20, an algebraic expression can be given as;

6(x) + 3.20 = 18.20

Here x is the price of one candy box

Solving for x;

6x = 18.20 - 3.20

6x = 15

x = 15 / 6

x = 2.50

Hence the price of one candy box is calculated to be $2.50.

Juniper spends $1300 out of the monthly income of $3250 on rent

Total income of Juniper = 3250 each month

Income is the money that an individual or organization receives in return for their services or goods. Depending on the context—such as taxation, financial accounting, or economic analysis—income may have a variety of definitions.

Percentage of expenditure on rent = 40%

Percentage of expenditure on food = 15%

Percentage of expenditure on utilities = 18%

The percentage for savings = 15%

Percentage of expenditure for personal items = 8%

Money Juniper spends on rent each month out of total income:

Using the graph obtained value of k is 1/3. Option C is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that

f(x) and g(x) = f(k-x),

The standard equation of a line is,

y = mx + b

The slope of the line for the coordinate points are (1, 2) and (1.5, 5)

m = 5-2/1.5-1

m = 3/0.5

m = 6

The y-intercept of the line is,

2 = 6(1) + b

2 - 6 = b

b = -4

As a result the obtained  equation is g(x) = 6x - 4

For the other coordinate point (3, 2) and (2, 0), the slope is

m = 0-2/2-3

m = -2/-1

m = 2

The y-intercept of the line is,

2 = 2(3) + b

2 - 6 = b

b = -4

As a result the obtained equation will be f(x) = 2x - 4.

Substitute xk at the place of x in the function as

f(xk) = 2(xk)- 4

If g(x) to f(k⋅x)

The trapezoid's area can be understood as triangle a + triangle b. So, we write these triangles as an expression, and, since we cannot solve with no values, we simplify to prove the area of the trapezoid.

A triangle's area is 1/2bh. In their case, b is represented as b or a depending on the triangle.

t = 1/2ah + 1/2bh

Now, since both expressions use the terms 1/2 and h, distributed onto a second variable, it can be rewritten as a single expression where both are distributed onto both variables at the same time. This is because both terms being multiplied by something separately is the same as combining both terms and multiplying them both at the same time.

t = 1/2(a)h + 1/2(b)h
t = 1/2(a + b)h

The graph that matches the data on the table, representing the altitude and time of a hawk is the straight line graph in the second option.

A straight line graph is the graph of a linear function or relationship

From the he values in the given, we have;

The difference between the consecutive altitude values (the first difference) = 70 - 80 = 60 - 70 = 50 - 60 = -10 is constant

The difference between consecutive time values = 1

Therefore;

The relationship is a linear relationship and the graph is a straight line.

Slope of the graph = -10/1 = -10

The equation in point and slope form is therefore;

(y - 80) = (-10) × (x - 1) = -10•x + 10

(y - 80) = -10•x + 10

y = 80 + 10 - 10•x = 90 - 10•x

y = 90 - 10•x

The y–intercept = 90

The slope = -10

The correct option is therefore the second graph that has the altitude (ft) on the the vertical axis and the time (s) on the horizontal axis, with a straight line decreasing from left to right starting at the point (0, 90) on the left

The probability that the events (a) they both picked Limca = 0.04, (b) Ademola only picked Pepsi = 0.32, (c) They both picked the same brand = 0.33 (d) They picked different brand=0.67.

Probability is the fraction of the required outcome event divided by the number of possible outcomes of events.

Total possible outcome of the event of picking drinks contained in the crate = 19

Hence, we can compute the following as follows;

(a) The probability they both picked Limca = (4/19)×(3/18)

Limca = 12/342

Limca = 0.04

(b) The probability Ademola only picked pepsi = 6/19

pepsi = 0.32

(c) The probability they both picked the same brand = (9/19)×(8/18)+(6/19)×(5/18)+(4/19)×(3/18)

=(72+29+12)/342

= 114/342

= 0.33

(d) The probability they picked different brand = (9/19)×(6/18)+(9/19)×(4/18)+(6/19)×(9/18)+(6/19)×(4/18)+(4/19)×(9/18)+(4/19)×(6/18)

The probability they picked different brand = (54+36+54+24+36+24)/342

The probability they picked different brand = 228/332

The probability they picked different brand = 0.67

Therefore, the probability for events (a) is 0.04, (b) is 0.32, (c) is 0.33 and (d) is 0.67.
