Final answer:

The model diameter of the bicycle wheel is found using the scale factor of 1:5 and the actual diameter of 24 inches (2 feet). By setting up a proportion and solving for the model diameter, we find it to be 4.8 inches.

Explanation:

To find the missing diameter of the bicycle wheel model when given the actual diameter and a scale factor, we use a proportion:

The scale is given as 1:5, which means 1 unit on the model represents 5 units in reality. First, we need to convert the actual diameter of 2 feet into inches because the model's diameter will be given in inches. There are 12 inches in 1 foot, so 2 feet is 24 inches.

After calculating, the model diameter is 4.8 inches.

Step-by-step explanation:

[tex]x + 15 \degree = 102 \degree \: \\ (corresponding \: \angle s) \\ \therefore \: x = 102 \degree - 15 \degree \\ \huge \red { \boxed{\therefore \: x = 87 \degree}}[/tex]

The value of x according to the relationship between the angles is; x= 87°

By mathematical convention, Corresponding angles (otherwise called F-angles) are equal.

On this note; the angle 102° and x +15° are equal.

Therefore,

x = 87°.

Question 1

The given system of equations is:

[tex]y = {x}^{2} + 5x + 6 \\ y = 3x + 6[/tex]

Equate the two equations:

[tex] {x}^{2} + 5x + 6 = 3x + 6[/tex]

Rewrite in standard form:

[tex] {x}^{2} + 5x - 3x + 6 - 6 = 0[/tex]

[tex] {x}^{2} + 2x = 0[/tex]

[tex]x(x + 2) = 0[/tex]

[tex]x = 0 \: or \: x = - 2[/tex]

When we put x=0, in y=3x +6, we get:

[tex]y = 3(0) + 6 = 6[/tex]

One solution is (0,6)

When we put x=-2, into y=3x+6, we get:

[tex]y = 3( - 2) + 6 = 0[/tex]

Another solution is (-2,0)

The solutions are; (0,6) and (-2,0)

Question 2:

The function is

[tex]f(x) = {x}^{6} - {x}^{4} [/tex]

Let us put x=-x,

[tex]f( - x) = {( - x)}^{6} - {( - x)}^{4} [/tex]

This gives:

[tex]f( - x) = {x}^{6} - {x}^{4} [/tex]

We can observe that:

[tex]f(x) = f( - x)[/tex]

This is the property of an even function.

Question 3:

The given function is

[tex]f(x) = {x}^{2} + 3x - 2[/tex]

The average rate of change of f(x) from x=a to x=b is given as:

[tex] \frac{f(b) - f(a)}{b - a} [/tex]

This is the slope of the secant line connecting the two points on f(x)

From x=2 to x=6, the average rate of change

[tex] = \frac{f(6) - f(2)}{6 - 2} \\ = \frac{ {6}^{2} + 3 \times 6 - 2 - {2}^{2} - 3 \times 2 + 2 }{4} \\ = \frac{36 + 18 - 4 - 6}{4} \\ = \frac{44}{4} \\ = 11[/tex]

The average rate of change is 11

Answer: there both equal

Step-by-step explanation: first we have to find the unit rate of both. Francisco unit rate for his recipe is 12/18=6/9=2/3 so the unit rate is 2/3

Nia uses 8/12=4/6=2/3 so the both will have the same if they use 6 ounces

Final answer:

Both Francisco and Nia use a proportional amount of milk in their smoothies; thus, they would both use 4 ounces of milk for 6 ounces of fruit.

Explanation:

To determine who would use more milk if they each use 6 ounces of fruit, we need to compare Francisco's and Nia's milk-to-fruit ratios. Francisco uses 12 ounces of milk for every 18 ounces of fruit, and Nia uses 8 ounces of milk for every 12 ounces of fruit. To find how much milk they would use for 6 ounces of fruit, we can set up a proportion for each and solve for the amount of milk.

For Francisco:
12 ounces of milk / 18 ounces of fruit = x ounces of milk / 6 ounces of fruit.
Using cross-multiplication, we get:
18x = 12 × 6.
Dividing both sides by 18 gives us:
x = (12 × 6) / 18 = 4 ounces of milk.

For Nia:
8 ounces of milk / 12 ounces of fruit = y ounces of milk / 6 ounces of fruit.
Using cross-multiplication, we get:
12y = 8 × 6.
Dividing both sides by 12 gives us:
y = (8 × 6) / 12 = 4 ounces of milk.

Therefore, both Francisco and Nia would use 4 ounces of milk for 6 ounces of fruit in their smoothie recipes.

Area of the figure is 71.13

Step-by-step explanation:

Find the area of the semicircle. Here, radius = 3.

Area = 1/2 πr² = 1/2 × 3.14 × 3² = 14.13

Area = length × width = 8 × 6 = 48

Area = 1/2 × base × height = 1/2 × 3 × 6 = 9

Area of the figure = 14.13 + 48 + 9 = 71.13

Answer:

I collect 4 rocks and 16 fossils. While my friend collects 12 rocks and 8 fossils.

Step-by-step explanation:

The number of total objects collected by me  = 20

The number of objects collected by my friend  = 20

Let us assume:

The number of rocks collected by me  = m

The number of fossils collected by me  = 2 k

⇒ m +  2 k =  20  .... (1)

So, according to the question:

The number of rocks collected by my friend = 3 x (rocks collected by me)  

= 3 x (m)  = 3 m

The number of fossils collected by my friend = 1/2 x (fossils collected by me)    = 1/2 x (2k )  = k

⇒ 3 m +   k =  20  .... (2)

Solving (1)and (2) for the value of m and k, we get:

m +  2 k =  20     ⇒ m = 20 - 2 k ... Put this in (2)

3 m +   k =  20  ⇒  3 (20 - 2 k) +  k = 20

⇒ 60 - 6 k +  k  = 20

or, - 5k = -40

or, k = 40/5  = 8

⇒ k= 8

m + 2(8)  = 20

or, m = 4

Hence, the number of rocks collected by me  = m = 4

The number of fossils collected by me  =  2 k = 2 (4)  = 16

Hence, the number of rocks collected by my friend   = 3 m  = 3 x 4 = 12

The number of fossils collected by my friend   =   k =  8

Hence, I collect 4 rocks and 16 fossils. While my friend collects 12 rocks and 8 fossils.

You collect 4 rocks and 16 fossils. Your friend collects 12 rocks and 8 fossils.

You and your friend each collect 20 objects. Let's define our variables:

Let R represent the number of rocks you collect. Let F represent the number of fossils you collect.

You collect 20 objects in total:

R + F = 20

Your friend collects three times as many rocks and half as many fossils as you:

Rocks: 3R Fossils: F / 2

Your friend also collects 20 objects in total:

3R + F / 2 = 20

We have two equations:

R + F = 20 and 3R + F / 2 = 20

First, solve equation 1 for F:

F = 20 - R

Next, substitute this into equation 2:

3R + (20 - R) / 2 = 20

Multiply everything by 2 to clear the fraction:

6R + 20 - R = 40

Simplify:

R + 20 = 40

Subtract 20 from both sides:

5R = 20

Divide by 5:

R = 4

Now, substitute R back into the equation for F:

F = 20 - 4

F = 16

Then, 3R= 12 and F/2 = 8

Thus, you collect 4 rocks and 16 fossils.  Your friend collects 12 rocks and 8 fossils.

Answer:

Bayes' theorem, was named after a  British mathematician from the 18th-century named Thomas Bayes. The Bayes´ theorem is a mathematical formula for determining conditional probability. The theorem provides a way to revise any existing predictions or theories, and given new or additional evidence. It updates probabilities.

Hope it helps answer the question:)

Final answer:

Bayes' Theorem is a principle in statistics used to update the probability of a hypothesis in light of new evidence. It combines prior knowledge with observed data to estimate probabilities, and is widely applicable in different fields for making informed decisions.

Explanation:

Understanding Bayes' Theorem

Bayes' Theorem is a fundamental concept in the field of probability and statistics. It offers a way to revise existing predictions or theories in light of new evidence. Bayes' theorem states that the probability of A occurring given that B has occurred is P(A|B) = P(A and B) / P(B). In Bayesian analysis, this is often expressed as the probability of a hypothesis given observed data. The formula can be expanded to include prior knowledge by considering the probability of the hypothesis before observing the data, P(A), and the likelihood of observing the data given the hypothesis, P(B|A).

The theorem has extensive applications across various fields, including science, engineering, and even history. For instance, it can be utilized for the estimation of probabilities of unobserved traits, such as determining the age of individuals based on skeletal indicators. By considering prior knowledge and observed data, Bayes' theorem provides a powerful tool for updating beliefs and making informed decisions.

In practice, Bayesian approaches can incorporate prior information that quantifies existing knowledge about a parameter, which can lead to greater certainty in parameter estimates. The use of Bayesian models is often facilitated by software like WinBUGS, which helps in applying complex Bayesian methods to practical problems

The area of the shaded region is 0.7257.

The area of the shaded region represents the probability that a standard normal variable will be less than 0.74.

Since the standard normal distribution is symmetrical, the area less than -0.74 is equal to the area greater than 0.74, which can be found using the standard normal table or a calculator.

Using the standard normal table, we find that the area less than -0.74 is 0.2743.

Therefore, the area greater than 0.74 is also 0.2743.

The total area under the curve is 1, so the area less than 0.74 is 1 - 0.2743 = 0.7257.

To solve for A and B, we translated the word problem into two algebraic equations and then solved the system of equations step-by-step to find that A equals 200 and B equals 250.

Explanation:

We are given two equations based on the relationship between 30% of number A and 20% of number B, and vice versa. Let's translate the words into algebraic expressions where A and B represent the numbers we need to find:

0.30A = 0.20B + 10 (Equation 1)

0.30B = 0.20A + 35 (Equation 2)

Now let's solve this system of equations step-by-step:

Multiply both sides of Equation 1 by 10 to clear out decimals: 3A = 2B + 100.

Multiply both sides of Equation 2 by 10 as well: 3B = 2A + 350.

Rearrange Equation 1 to get A on its own: A = (2B + 100) / 3.

Substitute the expression for A from step 3 into Equation 2: 3B = 2((2B + 100) / 3) + 350.

Multiply through by 3 to clear the fraction: 9B = 4B + 200 + 1050.

Simplify to find B: 5B = 1250, so B = 250.

Substitute B back into the equation from step 3 to find A: A = (2(250) + 100) / 3, so A = 200.

Therefore, the numbers we are looking for are A = 200 and B = 250.
