Answer:

Step-by-step explanation:

Let's call the length of the winning jump "w".

Sarah's best jump is 12% more than her first jump, which was 4.25m. So her best jump was 4.25m * 1.12 = 4.77m.

However, her best jump is 15% lower than the winning jump, so we can set up an equation to solve for w:

4.77m * 1.15 = w

Solving for w:

w = 4.77m * 1.15 = 5.51m

So the winning jump was 5.51m.

The parabola's shape is influenced by the separation between its focus and vertex. The parabola becomes wider as the vertex is focused further away (flatter).

A parabola is a plane curve created when a point moves in such a way that the distance it travels from a fixed point to a fixed line. The parabola's directrix serves as the fixed line, while the focus, represented by the letter F, serves as the fixed point. The line through the F and perpendicular to the directrix is the parabola's axis.

2. As illustrated here, the parabola's shape is influenced by the separation between its focus and vertex.

The parabola becomes wider as the vertex is focused further away (flatter).

The parabola becomes thinner as the vertex comes into focus (steeper).

3. If a > 0 in the quadratic equation the parabola opens upward and if a< 0 then the parabola opens downward.

4. The vertex of the parabola is the location where it crosses the axis.

More weight on one side of a balance scale will tip the scale in that direction is relationship is an example of causation.

Causation is the capacity of one variable to influence another.

Causation means that a change in one variable results in a change in another variable.

More weight on one side of a balance scale will tip the scale in that direction.

In this case, adding more weight to one side of the scale will directly cause it to tip in that direction.

There is a correlation between the variables, but it's not necessarily a direct cause-and-effect relationship.

The more education a person has, the more they read suggests that education and reading are correlated, but having more education doesn't necessarily cause a person to read more.

The total number of ways to form 3 groups comprising of 3, 3 and 2 students is calculated by multiplying the individual numbers of ways, which results in 280.

The formula for calculating the number of unique ways to form three groups comprising of 3, 3, and 2 students is given by:

Number of ways = Number of ways to select 3 first-year students from 5 first-year students x Number of ways to select 3 second-year students from 3 second-year students x Number of ways to select 2 students from 8 students

=[tex]5C3 x 3C3 x 8C2[/tex]

= 10 x 1 x 28

= 280

Therefore, there are 280 unique ways to form three groups comprising 3, 3, and 2 students. This can be seen by considering the total number of possible arrangements of the 8 students into 3 groups of 3, 3 and 2. First, we need to select 3 students from 5 first-year students in 5C3 ways, which is equal to 10. Second, we need to select 3 students from 3 second-year students in 3C3 ways, which is equal to 1. Finally, we need to select 2 students from 8 students in 8C2 ways, which is equal to 28. Therefore, the total number of ways to form 3 groups comprising of 3, 3 and 2 students is calculated by multiplying the individual numbers of ways, which results in 280.

The probability of exactly 5 patients having kidney-related problems is approximately 0.253 or 25.3%.

The probability of a given number of patients having kidney-related problems can be found using the binomial distribution. The binomial distribution models the number of successful outcomes in a fixed number of independent trials, where each trial has the same probability of success.

In this case, each hospital admission is a trial, and the probability of success (having a kidney-related problem) is 0.3 (30%). The number of trials is 10, and we want to find the probability of exactly 5 patients having kidney-related problems.

We can use the formula for the probability mass function of the binomial distribution to find this:

[tex]P(X = k) = (n choose k) * p^k * (1-p)^(n-k)[/tex]

where:

n = 10 (number of trials)

k = 5 (number of successful outcomes)

p = 0.3 (probability of success)

Using the formula, we have:

[tex]P(X = 5) = (10 choose 5) * 0.3^5 * (1-0.3)^(10-5)= 252 * 0.3^5 * 0.7^5[/tex]

= approximately 0.253

The two numbers, then, are 86 and 61.The two numbers can be found by using basic algebra.

The two numbers can be found by using basic algebra. To solve for the two numbers, we can set up two equations, one for the sum and one for the difference. For the sum, we can set up the equation: x + y = 147. For the difference, we can set up the equation: x - y = 25. We can then solve for x by adding y to both sides of the equation for the difference, so x = 25 + y. We can then substitute this value for x in the equation for the sum, so 25 + y + y = 147, or 2y = 122, and y = 61. We can then substitute this value for y in the equation for x, so x = 25 + 61, or x = 86. The two numbers, then, are 86 and 61.

you cannot cancel (5-5) because it is multiplied to 5 and 4 if the question was 5+(5-5)=4+(5-5) you can cancel 5-5

The reason that we can't cancel out the (5 - 5) is because it is attached to different numbers and as such they must be multiplied first with distributive property.

According to the distributive property of algebra, multiplying the sum of two or more addends by a number will give us the same result as when each addend is multiplied individually by the number and the products are added together.

This also applies to addition as well.

The coordinates of Casper which lies exactly in the middle of Denton and Beacon are (-4, -1).

Coordinates are defined as the set of points in a coordinate plane or space, which describes the position of that point in that plane or space.

In a coordinate plane, the midpoint of two points (x₁, y₁) and (x₂, y₂) is the point (x, y) such that their measures are,

x = (x₁ + x₂) / 2

y = (y₁ + y₂) / 2

First, we can write the given measures.

Coordinates of Albion = (5, 5)

Coordinates of Denton = (-7, -3)

Given that, Beacon is lying exactly in the middle of Albion and Denton.

Let the coordinates of Beacon be (x, y).

Using the formula above,

x coordinate of Beacon = (5 + -7) / 2 = -1

y coordinate of Beacon = (5 + -3) / 2 = 1

Coordinates of Beacon are thus (-1, 1).

Casper is lying exactly in the middle of Denton(-7, -3) and Beacon (-1, 1).

Let (x' , y') be the coordinates of Casper.

Answer: The bushes cost $8 and the shrubs cost 7$

Step-by-step explanation:

For this question you must use system of equations, trial and error will take a very long time.

So yeah, here is how you solve it-

First set up equations (b represents the amount of bushes and s represents the amount of shrubs):

5b + 1s = 47

10b+4s=108

Next you can either solve via elimination or the substitution method. I will show elimination here. Elimination works by slightly modifying one of the equations so that it cancels when it is added to the other equation:

(I modified the first equation)

-4(5b+1s = 47) = -20b-4s=-188

(Then add)

     -20b-4s=-188

  +    10b+4s=108

This equals: -10b=-80

Next you just solve for b:

b=-80/-10

b=8

To then find s, plug b into one of the original equations and solve for s:

(I plugged it into the first equation)

5(8)+1s=47

40+s=47

s=7

So the bushes cost $8 and the shrubs cost 7$

1) The probability of picking more than 1 apple is 0.8. 2) the expected number of apples you can pick each year is 2.65. 3) the expected number of apples you can pick each year is 2.65.

To find the probability of picking more than 1 apple, we need to find the sum of the probabilities of picking 2, 3, and 4 apples. Using the table, we have P(N>1) = P(2) + P(3) + P(4) = 0.15 + 0.35 + 0.3 = 0.8. So, the probability of picking more than 1 apple is 0.8. The expected number of apples you can pick each year can be calculated using the formula: E(N) = ∑N * P(N), where the sum is taken over all possible values of N. Using the table, we have E(N) = (1 * 0.1) + (2 * 0.15) + (3 * 0.35) + (4 * 0.3) = 0.1 + 0.3 + 1.05 + 1.2 = 2.65. So, the expected number of apples you can pick each year is 2.65. To find the probability of picking 3 apples, given that your father picked more than 1 apple, we need to use the conditional probability formula. We have P(3|N>1) = P(3 and N>1) / P(N>1) = P(3) / P(N>1) = 0.35 / 0.8 = 0.4375. So, the probability of your father picking 3 apples, given that he picked more than 1 apple, is 0.4375

The probability of the intersection of two events occurring can never be more than the probability of the union of two events occurring.

False.

It should be stated that the likelihood of the intersection of two events occurring is always less than the likelihood of the events occurring together.

It is always less likely than or equal to the likelihood of either event occurring alone for an intersection of two events, which is the chance that both occurrences take place.

In other words, the probability of the intersection and the probability of the union are subsets of one another.

The chance of the intersection of two events occurring can never be greater than the likelihood of the union of two events occurring, hence that is the right statement.

a) The probability that a hand will contain exactly 2 wild cards is 0.0246.

b) The probability of choosing a hand with seven yellow cards is 0.00056.

a) To find the probability that a hand will contain exactly 2 wild cards, we need to consider the number of ways we can choose 2 wild cards from 8 and the number of ways we can choose 5 non-wild cards from the remaining 100 cards. The total number of ways to choose 7 cards from 108 is:

C(108, 7) = 85,900,584

The number of ways to choose 2 wild cards from 8 is:

C(8, 2) = 28

The number of ways to choose 5 non-wild cards from the remaining 100 cards is:

C(100, 5) = 75,287,520

Therefore, the total number of ways to choose a hand with exactly 2 wild cards is:

28 * 75,287,520 = 2,108,196,160

The probability of choosing a hand with exactly 2 wild cards is:

2,108,196,160 / 85,900,584 ≈ 0.0246, or about 2.46%

b) To find the probability that a hand contains seven yellow cards, we need to calculate the number of ways we can choose 7 yellow cards from the 25 available, and divide this by the total number of ways to choose 7 cards from the 108 available. The number of ways to choose 7 yellow cards from 25 is:

C(25, 7) = 48,048

The total number of ways to choose 7 cards from 108 is:

C(108, 7) = 85,900,584

Therefore, the probability of choosing a hand with seven yellow cards is:

48,048 / 85,900,584 ≈ 0.00056, or about 0.056%
