Can someone help me find the answer to this problem.
Jake finished 3/4 of a race in four hours, how long was the entire race?

Answer:

B.   3,158

Step-by-step explanation:

h(x) = -49x − 125

Let x = -67

h(-67) = -49(-67) − 125

          =3283-125

          = 3158

Answer:

Answer B

Step-by-step explanation:

To find the value of h(-67) for the function h(x) = -49x - 125,

we substitute -67 for x in the function and evaluate it.

h ( - 67 ) = - 49 ( - 67 ) - 125

Now we can simplify the expression:

h ( -67 ) = 3283 - 125

h ( -67 ) = 3158

The theoretical probability of stopping on the color blue when spinning a spinner with the colors red, yellow, blue, and green is 25% or 1/4.

A spinner is a tool that spins around an arrow or a pointer that points towards the numbers, colors, or pictures around its edge. The probability of a certain event is the likelihood of that event occurring. In this case, we need to find the theoretical probability of stopping on the color blue.

We have four colors on the spinner, so the probability of stopping on blue can be found using the formula of theoretical probability.

The formula for theoretical probability is:

number of favorable outcomes / total number of outcomes.

Since we have four colors on the spinner, the total number of outcomes is 4. The favorable outcomes are the number of times the spinner will land on blue, which is 1.

So the probability of stopping on the color blue can be calculated as follows:

1 (favorable outcome) / 4 (total number of outcomes) = 1/4

So, the theoretical probability of stopping on the color blue is 1/4. This is because there is an equal chance of landing on any of the four colors, and since there are four colors, each has a 25% chance of being selected.

Answer:

Horizontal translation in the \(+x\) direction.

Step-by-step explanation:

A function of the form \(f(x)\) experiments an horizontal translation when the following substitution is applied:

\(x \to x + a\), where \(a \in \mathbb{R}\)

If \(a > 0\), the function is translated in the \(-x\) direction, whereas \(a < 0\) is the case for the function being translated in the \(+x\) direction.

The effect on the graph can be defined by a composition between two function:

\(f(x) = x^{2}\), \(g (x) = x-6\)

\(f\,\circ\,g\,(x) = (x-6)^{2}\)

The resulting expression represents a horizontal translation in the \(+x\) direction.

Finally, we plot \(f(x)\) (red) and \(f\,\circ g\,(x)\) (blue) by a graphing tool and proved the certainty of this theory.

The probability that it is gold is (1/3).

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. If two events are mutually exclusive, then there is a 0 percent chance that they will both happen at the exact moment. Two events are said to be mutually exclusive if they share no elements (their intersection is the empty set). Consequently, P(A∩B)=0.

Let A be the event that a gold marble is picked.

Let B₁ and B₂ be the event that the first bag is chosen and the second bag is chosen respectively.

Given: P (B₁ ) = 2.P(B₂)

Also, P(B₁) + P(B₂) = 1

∴ 2P(B₂) + P(B₂) =1

3P(B₂) = 1

P(B₂) = 1/3 and  P(B₁) = 2/3

Now

P(A)

= P(A∩(B₁∪B₂))

= P[(A∩B₁)∪(A∩B₂)]

Probability adds up because the events are mutually exclusive

= P(A∩B₁) + P(A∩B₂)

= P(B₁). P(A/B₁) + P(B₂). P(A/B₂)

= (2/3)×(3/16) + (1/3)×(15/24)

= (1/3)

Answer:

If function is given by its table representation and you have to determine what type of function it is, you can’t be 100% sure that the given function is linear. Why is that so? Because there are many functions which have the same table representation.

Example: You’re given f(0)=0 and f(1)=1. It can be representation of function f(x)=x, f(x)=x^2, f(x)=x^3 etc. If there are more given datas, maybe you can eliminate some types of functions, but you can’t be sure what type of function it is. :)

a linear function is used to relate to relate an independent variable and a dependent variable by introducing a rate of change(function) of which the independent variable is equated to find the dependent variable for example y=3x hence hence is the dependent variable as it depends on the change of x and 3 is the rate of change which is a constant and is determined by the division of the values of y/x hence to make a table of y over x of which y is determined by the rate of change 3*the independent variable x

Step-by-step explanation:

So, lets think about the information we are given.

Sammy earns 23,400 in a given year.

In a year, he works 52 weeks.

Per week, he works 30 hours.

Find hours -> find pay.

To find hours, multiply number of weeks by hours

52 * 30 = 1560

He works 1560 hours per year.

To find hourly income, divide total money per year by hours per year.  He makes 15 dollars per hour.

Find $ per week.

Hourly rate by hours per week

15 * 30 =450 per week

Hope this helps :)

Answer:

Sami had an hourly pay rate of $15 an hour

Step-by-step explanation:

Multiply 52 by 30 and you get 1,560, this is the total number of hours sami worked in a year.

If Sami made $23,400 in one year and worked 1,560 hours, you divide the total amount of hours work and total amount of money made to get an hourly pay rate of $15 an hour.

Answer:

The value of k is -4.

Step-by-step explanation:

In order to find the value of k, you have to substitite x = -1/2 into the equation :

\(2 {x}^{2} - 7x + k = 0\)

\(let \: x = - \frac{1}{2} \)

\(2 {( - \frac{1}{2} )}^{2} - 7( - \frac{1}{2} ) + k = 0\)

\(2( \frac{1}{4} ) + \frac{7}{2} + k = 0\)

\( \frac{1}{2} + \frac{7}{2} + k = 0\)

\(4 + k = 0\)

\(k = - 4\)

The standard error of the sample mean of 200 fill-ups by one driver is 0.2213.

The 2015 Subaru Outback is rated by the EPA at μ=28.0 mpg and a standard deviation of σ=3.13 mpg.

To calculate the standard error of the sample mean of 200 fill-ups by one driver, we can use the formula for standard error:

Standard error = σ/√n

Where,σ = standard deviation of the population (in mpg)n = sample size

To find the standard error of the sample mean of 200 fill-ups by one driver, we need to substitute the given values into the formula:

Standard error = σ/√n= 3.13/√200= 0.2213 (rounded to four decimal places)

Therefore, the standard error of the sample mean of 200 fill-ups by one driver is 0.2213.

Hence, the correct option is 0.2213.

Let r be a partial order on set S, and let t be a subset of S. If a and a' are both elements of t, where a is the greatest element and a' is a maximal element, then it can be proven that a = a'.

To prove that a = a', we consider the definitions of greatest and maximal elements. The greatest element in a set is an element that is greater than or equal to all other elements in that set. A maximal element, on the other hand, is an element that is not smaller than any other element in the set, but there may exist other elements that are incomparable to it.

Given that a is the greatest element in t and a' is a maximal element in t, we can conclude that a' is not smaller than any other element in t. Since a is the greatest element, it is greater than or equal to all elements in t, including a'. Therefore, a is not smaller than a'.

Now, to prove that a' is not greater than a, suppose by contradiction that a' is greater than a. Since a' is not smaller than any other element in t, this would imply that a is smaller than a'. However, since a is the greatest element in t, it cannot be smaller than any other element, including a'. This contradicts our assumption that a' is greater than a.

Hence, we have shown that a is not smaller than a' and a' is not greater than a, which implies that a = a'. Therefore, if a is the greatest element and a' is a maximal element in t, then a = a'.

Answer:

y = - \(\frac{5}{2}\) x - 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (- 2, 3) and (x₂, y₂ ) = (0, - 2) ← 2 points on the line

m = \(\frac{-2-3}{0-(-2)}\) = \(\frac{-5}{0+2}\) = - \(\frac{5}{2}\)

the line crosses the y- axis at (0, - 2 ) ⇒ c = - 2

y = - \(\frac{5}{2}\) x - 2 ← equation of line

Answer:

C. -1

Step-by-step explanation:

Find the y intercept by plugging in the slope and a given point into the equation y = mx + b. Then, solve for b:

y = mx + b

-7 = -3(2) + b

-7 = -6 + b

-1 = b

So, the y intercept is -1.

Step-by-step explanation:

XZ divides <WXY into two equal parts. Which implies that:

m<ZXY = m<ZXW

Therefore:

m<WXY = 2(m<ZXY)

m<ZXY = 58°

m<WXY = 2x + 2

Plug in the values into the equation

2x + 2 = 2(58)

2x + 2 = 116

2x = 116 - 2 (subtraction property of equality)

2x = 114
