Answer:

The x-intercept of the line will be (10, 0)

Step-by-step explanation:

start from -12

get to -2...

-12 + (10) = -2

-2 + (10) = 8

therefore, the x-intercept is (10, 0)

The equation for the linear function f(x) is f(x) = 2 / 7 x - 10 / 7

The linear function is f(x)

f(-2) = - 2 and f(5) = 0

Therefore, let's find the equation for the linear function f(x):

A linear function is a function that represents a straight line on the coordinate plane.

Therefore, linear function is represented as follows:

y = mx + b

where

Hence,

-2 = m(-2) + b

0 = 5m + b

b = -5m

Therefore,

m(-2) + - 5m = -2

-2m - 5m = -2

-7m = -2

m = 2 / 7

Therefore,

b = - 5 (2 / 7)

b = - 10 / 7

Hence,

f(x) = 2 / 7 x - 10 / 7

The solution in interval notation is; (-∞,  49/2).

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

To solve the equation 5/16x - 7/4 < 3/4x + 21/2, we can simplify both sides:

5/16x - 7/4 < 3/4x + 21/2

Combining like terms:

5/16x  -3/4x  < 21/2 + 7/4

8/16x < 49/4

1/2x < 49/4

Simplifying the fraction;

x < 49/2

Therefore, the solution in interval notation is (-∞,  49/2).

The value of x for the given triangle is 38.66° to the nearest hundredth.

Given a right angled triangle.

We have to find the angle marked as x for the given triangle.

Also given that two of the side lengths as 10 cm and 8 cm.

We can use trigonometric ratio to find the length of the unknown angle or x.

We know that,

tan (x) = Opposite side / Adjacent side

Using this function,

tan (x) = 8/10

tan (x) = 0.8

x = tan⁻¹ (0.8)

x = 38.66°

Hence the angle is 38.66°.

Whenever two variables are correlated, we assume that one variable is the cause of the observed effect from the other variable.

It is a false statement,

Two variables that move together, or in the same direction, are said to have a positive correlation. When one variable rises while the other rises or when one variable falls while the other falls, there is a positive correlation. These two separate variables are theoretically influenced by the same outside factors because they travel in the same direction.

The approximate probability that exactly 97 out of 151 people will not get the flu this winter is 0.6732, rounded to four decimal places.

Let X be the number of people who do not get the flu this winter. We are interested in finding the probability that X = 97, given that there are 151 people in total and the probability of any given person not getting the flu is 0.64.

Since the number of people who do not get the flu this winter follows a binomial distribution with parameters n = 151 and p = 0.64, we can approximate it using a normal distribution with mean μ = np = 151 × 0.64 = 96.64 and variance σ² = np(1 - p) = 151 × 0.64 × 0.36 = 34.7136.

To apply the normal approximation, we need to standardize the value of X = 97:

Z = (X - μ) / σ = (97 - 96.64) / sqrt(34.7136) ≈ 0.4552

where sqrt denotes the square root function.

Now, we use a standard normal distribution table or calculator to find the probability that a standard normal variable is less than or equal to 0.4552:

P(Z ≤ 0.4552) ≈ 0.6732

Therefore, the approximate probability that exactly 97 out of 151 people will not get the flu this winter is 0.6732, rounded to four decimal places.

Answer:

Ashley can serve 12 pieces of pizza in the party

Step-by-step explanation:

To solve this question we need to convert the 9 pizzas to decimal:

9 times 4 = 36. That is:

9 pizzas are equal to 36/4 of pizza (36/4 = 9)

As Ashley is serving 3/4 of a pizza she can serve:

36/4 ÷ 3/4 = 36/3 = 12

The optimal Bayesian classifier is the one that minimizes the probability of misclassification. This can be achieved by choosing the class that has the highest posterior probability given the observed data. In this case, we need to compare the conditional class probabilities P2(t) and P0(I) for each data point and choose the class with the higher probability.

To find the optimal Bayesian classifier, we need to find the values of a and b that define the decision boundary between the two classes. This can be done by setting P2(t) = P0(I) and solving for x:

P2(t) = P0(I)
Pr(Y; = 1|X, = x) = Pr(Y; = 0[Xi = 1)
1 - P2(I) = P2(I)
2P2(I) = 1
P2(I) = 0.5

Now we can solve for x to find the decision boundary:

0.5 = Pr(Y; = 1|X, = x)
0.5 = P2(I)
x = a + b

Therefore, the optimal Bayesian classifier is of the form:

if Xe [a, b] then yi = 1
if Xe [b, a] then yi = 0

where a and b are the values of x that satisfy P2(I) = 0.5.

we can conclude that 2/3 is not equal to 4/5.

To determine if 2/3 is equivalent to 4/5, we can compare the fractions by checking if their ratios are equal. The ratio of 2/3 can be written as 2:3, while the ratio of 4/5 can be written as 4:5.

To check if the ratios are equal, we can cross-multiply and see if the products are equal. Cross-multiplying means multiplying the numerator of the first fraction with the denominator of the second fraction, and the numerator of the second fraction with the denominator of the first fraction.

For 2/3 and 4/5, we have:

2 * 5 = 10

3 * 4 = 12

Since 10 is not equal to 12, we can conclude that 2/3 is not equivalent to 4/5.

Answer:

$43.20 total

$3.20 sales tax

Explication:

40*1.08=43.2

Answer:

sales tax = $3.20

total cost = $43.20

Step-by-step explanation:

To calculate the sales tax on an item, multiply the price of the item by the tax percent in decimal form. To convert a percent to decimal form, divide the percent by (100).

Sales tax percent: 8%

In decimal form: 0.08

Multiply the sales tax in decimal form by the price of the item to find out the sales tax amount,

(item_price) * (sales_tax)

= (40) * (0.08)

= 3.2

Sales tax amount: $3.20

To find the total cost of the product, add the sales tax amount to the item price,

(item_price) + (sales_tax_amount)

= 40 + 3.20

= 43.20

the height of a binary tree is the number of edges in the longest path from the root to a leaf.The best-case height of a binary tree with seven nodes is 3.

A binary tree is a type of tree structure consisting of nodes that are connected by edges. The number of edges in the longest path from a binary tree's root to a leaf determines the tree's height.In the best-case scenario, the binary tree is perfectly balanced and each node has exactly two children. With seven nodes, the best-case height is three because each node has two children and three edges connect the root node to the leaves. This means that the longest path from the root to a leaf is three edges, resulting in a height of three.

Answer:

Step-by-step explanation:

Let's represent the number with the variable "x". According to the given property, we can write the following equation:

3(x + 4) < 7x

Now, let's solve this inequality to find the range of numbers that satisfy the property.

3x + 12 < 7x

Subtract 3x from both sides:

12 < 4x

Divide both sides by 4 (since the coefficient of x is 4):

3 < x

So, the range of numbers that satisfy the given property is x > 3.

Therefore, any number greater than 3 will satisfy the condition. For example, 4, 5, 6, 7, 8, etc.Step-by-step explanation:

Using Pythagoras Theorem

(Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2

(Hyp)^2 = (21)^2 + (72)^2

(Hyp)^2 = 441 + 5184

(Hyp)^2 = 5625

Taking √ on both sides

Hypotenuse = √5625

Hypotenuse = 75

Therefore the missing length is 75m

Answer:

Step-by-step explanation:

Because of the Pythagorean Theorem, which states that a^2 + b^2 =c^2, we can find the missing side length:

1. 21^2 = 441

  72^2 = 5184

2. 441 + 5184 = 5625

3. Since the question is asking for c (the missing side length), not c^2, we square root 5625:

  √5625 = 75

Therefore, the missing side length is 75.

The total number of possible outcomes is given by the expression 6n × 52, where n represents the number of marbles to choose from.

To determine the number of possible outcomes, we need to consider the number of outcomes for each event and then multiply them together.

1. Picking a marble: Let's assume there are n marbles to choose from. If there are n marbles, then the number of outcomes for this event is n.

2. Rolling a die: A standard die has 6 sides numbered 1 to 6. Therefore, the number of outcomes for this event is 6.

3. Picking a card: A standard deck of cards has 52 cards. Hence, the number of outcomes for this event is 52.

To find the total number of possible outcomes, we multiply the number of outcomes for each event together:

Total number of outcomes = (number of outcomes for picking a marble) × (number of outcomes for rolling a die) × (number of outcomes for picking a card)

Total number of outcomes = n × 6 × 52

Therefore, the total number of possible outcomes is given by the expression 6n × 52, where n represents the number of marbles to choose from.
