Step-by-step explanation:

If 9 seeds are planted, what is the probability that exactly 3 don't grow will be 1/5832000 as 5% chance are there that plant will not grow.

The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions. Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution.

Here,

The chances of seed to be not growing is 1–0.95 =0.05.

For 3 seeds not to grow being simultaneous occurring events have the probability = 0.05×0.05x0.05=0.000125

As 9 seeds being planted the probability of selecting 1 out of 9 is (1/9).

So for 3 mutual occurring case is (1/9)×(1/9)x(1/9)= 1/729

So the probability will be (1/729)×1/8000=1/58,32,000

The likelihood that exactly 3 seeds out of 9 will not germinate is 1/5832000, or 5%, so there is a chance that the plant won't grow.

The difference in solving equations with cubes and squares is of one additional step of reducing the cubic equation to a quadratic equation. In this way, a quadratic equation (variable raised to power 2) is separated from the given cubic equation.

For example, x3+3x2+x1+3=0 can be reduced to (x+3) and (x2+1), where the later one is a quadratic equation. This step is never part of a squared equation’s solution.

The similarity is from here onwards. Quadratic equations are solved similarly in both cases. Although there are multiple possibilities for roots differing from each other in nature. But once a quadratic equation is developed, the solution from there onwards is mostly generic.

Answer:

x = 3.5 hours

y = 1.5 hours

Step-by-step explanation:

There are two unknowns, x and y, both in umits of hours.  We need at least two equations before we start trying to solve this with substitution.  Looking at the information, this should be possible.

First, we know that Speed x Time = Distance.  

The distance covered by the cyclyst would be the sum of (12km/h)*x and (16km/h)*y, where x is the time, in hours, for the slower speed and y for the faster.  Together, the student travels 66 km.

The total distance of 66 km would be comprised of the two distances 12x and 16y:

 12x + 16y = 66 km  

For the second equation, we know that the total time is 5 hours.  That would be the sum of x and y:

 x + y = 5 hours

We now have 2 equations, so we stand a good chance of finding the answer.  Pick one of the equations and isolate one of the variables to one side.  Let's choose x + y = 5 hours, since that is easy to rearrange:

     x = 5-y

Now take the first equation and substitute the definition of x from above (5-y):

12x + 16y = 66

12(5-y) + 16y = 66

60-12y + 16y = 66

4y = 66-60

4y = 6

y = (6/4) or 1.5 h

The time spent at 16 km/h was 1.5 hours.

Use this value of y in either equation to find x.  Let's use x+y=5, since that will be easier:

x+y = 5 for y = 1.5

x+1.5 = 5

x = 3.5h

The time spent at 12 km/h was 3.5 hours

The probability of at least 15% of 100 Indianapolis residents supporting the patriots in gaint match Super Bowl XLVI is 0.293.

By using the normal distribution method, a mean u and standard deviation σ,

The ratio of people who wants the Giants to eat patriots is p = 0.90,

The assumed sample size denoted by n is 100,

and their distribution's mean is u = 0.90,

by using the standard deviation formula is

σ = √(p(1 - p) ÷ n),

σ = √(0.90(1 - 0.90) ÷ 100),

σ = 0.03,

we get that the standard deviation is σ = 0.03

Here the probability that at least 15% of 100 Indianapolis residents encouraged the Patriots in the gaint match  Super Bowl XLVI is

P(X > 0.15) = 1 - P((X - u) ÷ σ) > (0.90 - 0.15) ÷ 0.03))

The significant value of X,

X - u ÷ σ = Z

we get,

P(X > 0.75) = (Z<5)-1

P(X < 0.75) = 1.293 - 1

P(X < 0.75) = 0.293

By solving we get, The probability of at least 15% of 100 Indianapolis residents supporting the patriots in gaint match Super Bowl XLVI is 0.293.

The Probability of an odd number = 0.5.

What is Probability?

One of the areas of probability theory is the estimation of the chance of experiments occurring. Using probability, we can calculate everything from the possibility of getting heads or tails when flipping a coin to the likelihood of making a research error, for example. The formula for computing probabilities in equiprobable sample spaces, the probability of the complementary event, etc., as well as the likelihood of two occurrences coming together, are essential to understand in order to properly appreciate this field of mathematics.

In the given question, we have:

The odd numbers on the given spin are 1,3,5,7 and 9;

So, The number of odd numbers is 6;

That is, n(odd) = 6;

The expression equivalent to (-3.3x + (-3.2)) + (5.7x + (−1) is  -3.3x + 5.7x) + ((-3.2) + (-1))

The commutative property of addition states that any change in the order of the numbers being added does not affect the sum.

a + b = b + a

The given expression is  (-3.3x + (-3.2)) + (5.7x + (−1))

on simplifying we get, -3.3x - 3.2 + 5.7x - 1 = 2.4x - 4.2

Upon checking the options provided

-3.3x + (-3.2) + 5.7x + (-1)

Given:

The equation of the parabola that has the same shape has f(x) = 7x^2 but with vertex(3,5) in the form of f(x) = a(x-h)^2 + k.

If the parabola has same shape then its a values are same.

Using the relationship of permutation and combination, we can say that the relation [tex]${ }^n p_r=(n-\Gamma+1)^n p_{r-1}$[/tex] holds true.

What is Permutation?

The process of placing all the components of a set into a certain sequence or order is known as permutation in mathematics. In other terms, the process of permuting is the reordering of the components of a set if the set is already ordered. Nearly all areas of mathematics include permutations in some form or another. They frequently appear when various orderings on certain finite sets are taken into account.

What is Combination?

Contrary to permutations, the order of selection is irrelevant when choosing elements from a collection using the combination method. The number of combinations may be counted in simpler situations. The combination is the taking together of n items, k at a time, without repetition. The words k-selection or k-combination with repetition are frequently used to describe combinations when repetition is permitted.

In the given question:

The effect of eliminating the lowest value, 0, from the data set have on the mean and median of the data set is;

The mean of a given data is the sum of all observations divided by the number of observations

The median of a given set of data refers to the middlemost observation, obtained after arranging the data in ascending or descending order.

Given data:

0, 40, 60, 70, 75, 80, 85, 95, 95, 100

a) Mean without '0' = (40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100) / 9

= 700/9

= 77.777

Median without '0' = 40, 60, 70, 75, 80, 85, 95, 95, 100

= 80

Mean with ' 0' = 0+ 40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100 / 10 = 70

Median with '0' = 0, 40, 60, 70, 75, 80, 85, 95, 95, 100

= (75 + 80) / 2

= 77.5

So therefore,

Difference in mean = Median without '0' - Mean with ' 0'

= 77.77 - 70

= 7.7

Difference in median = Median without '0' - Median with '0'

= 80 - 77.5

1. An exponential equation modeling the skateboard's value, y, in x years is y = 380 x 1.07ˣ.

2. The value of the skateboard will be worth $610.28 in seven years.

An exponential equation is a mathematical function that depicts an equation with variable exponents.

The exponential function is always written in the form of y = abˣ.

Where a = the constant or initial value, b = the continuous growth rate, and x  or t = the time variable.

Y represents the value that we are looking for after the growth rate has been applied for several (t) years.

The current worth of the skateboard = $380

Annual increase = 7% = 0.07

Number of years = 7 years

Y = 380 x 1.07⁷

= 380 x 1.606

= 610.28

= $610.28

The required value of RT is 10 units when RS = 7, ST = 3x, and RT = x + 9.

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given below shows a line segment RT, where the length of line segment RT refers to the distance between its endpoints, R and T.

RS = 7, ST = 3x, and RT = x + 9

R______________S______________T

⇒ RT = RS + ST ....(i)

Substitute the values of RS = 7, ST = 3x, and RT = x + 9,

⇒ x + 9 = 7 + 3x

⇒ 3x - x = 9 - 7

⇒ 2x = 2
