Given:
The given term is -5.3+h/5=-19.4.
The objective is to find the value of h using inverse operation.
Inverse operation states that, if a term is in addition operation with another term, then it will change to subtraction operation while shifting to other side of the equation.
If a term is in multiplication operation, then it change to division operation while shifting to other side of the equation.
The value of h can be calculated as,
[tex]\begin{gathered} -5.3+\frac{h}{5}=-19.4 \\ \frac{h}{5}=-19.4+5.3 \\ \frac{h}{5}=-14.1 \\ h=-14.1(5) \\ h=-70.5 \end{gathered}[/tex]Thus, the value of h is -70.5.
Hence, option (c) is the correct answer.

Suppose a jar contains 20 red marbles and 31 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same time, find the probability that both are red.
Answers
The probability that they are both are red is 0.15.
What is probability?Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true.
The jar contains 20 red marbles and 31 blue marbles. The total marble is 51.
Therefore, the probability will be:
= P(red) × P(red)
= 20/51 × 19/50
= 380 / 2550
= 0.15
The probability is 0.15.

A population of beetles are growing accordingto a linear growth model. The initial population (week 0) isPo = 5, and the population after 7 weeks is P = 82.Find an explicit formula for the beetle population after n weeks..Pn-After how many weeks will the beetle population reach 258?weeks
Answers
Answer:
P(n) = 5 + 11n
n = 23 weeks
Explanation:
The equation for the population as a linear growth model has the form
P = P0 + an
Where P0 is the initial population, n is the number of weeks and a is the rate of increase per week. We know that P0 = 5, so
P = 5 + an
Additionally, when n = 7 the value of P = 82, so we can use this to find the value of a as follows
82 = 5 + a(7)
82 = 5 + 7a
82 - 5 = 5 + 7a - 5
77 = 7a
77/7 = 7a/7
11 = a
Therefore, the equation for the population after n weeks is
P(n) = 5 + 11n
Finally, to know the number of weeks to reach a population of 258, we need to replace P by 258 and solve for n, so
258 = 5 + 11n
258 - 5 = 5 + 11n - 5
253 = 11n
253/11 = 11n/11
23 = n
So, after 23 weeks the population will be 258.

What is termed as the exponential increase?An exponential function's curve is created by a pattern of data called exponential growth, which exhibits greater increases over time. Linear growth, which is additive, and geometric growth can be contrasted with exponential growth, which is multiplicative (that is raised to a power).Let P stand for the population in 2000 (or any other time period). Considering the equation:
P = 3485e∧0.12t,
The population in 2010 (t = 10 years) would be:
P = 3485e∧0.12×10
P = 3485e∧12
P = 11571
When there are 50,000 people in the population:
50,000 = 3485e∧0.12t,
Solving, by log property.
t = 22 years.
Thus, there are 11571 people in the world as of 2010, and would take about 22 years for that number to reach 50,000.

Given the function and the graph below, which of the following best describes the continuity, interval of increase and interval of decrease?
Answers
Given the function:
[tex]f(x)=(-x-1)^2+3[/tex]As we can see, there is no restriction for x, it can be any real value. Additionally, looking at the graph, we do not see any discontinuity ("jumps" or "holes"). We conclude that the function is always continuous.
The vertex of the parabola is at (-1, 3), so x = 1 separates the intervals of increase and decrease. Going from -∞ to -1, we see a decrease in the y-values. Similarly, from -1 to +∞, we see an increment. Then:
Interval of increase: -1 < x < +∞
Interval of decrease: -∞ < x < -1
