Step-by-step explanation:

The value of x is 3 days.

Here,

Jenna alone takes x days to finish a project.

Kelly alone takes 3 days more than Jenna alone to finish the project.

They together take 2 days to finish the project.

We have to find the value of x.

What is Mathematical expression?

Mathematical expression is a way where calculations and analytical processes should be observed.

Now,

Jenna alone takes x days to finish a project.

Hence, Jenna complete work in 1 day = 1/x work

Kelly alone takes 3 days more than Jenna alone to finish the project.

That is, x + 3 days.

Hence, Kelly complete work in 1 day = \(\frac{1}{x+3}\) work

They together take 2 days to finish the project.

Hence, They together complete a work in 1 day = 1/2 work.

To find the value of x we use the formula of work word problem as;

\(\frac{1}{x} + \frac{1}{x+3} = \frac{1}{2} \\\\\frac{(x+3)+x}{x(x+3)} = \frac{1}{2}\\\\2(2x+3) = x (x+3)\\\\4x + 6 = x^{2} + 3x\\\\x^{2} -x-6=0\\\\x^{2} -3x+2x-6=0\\\\x (x-3) +2(x-3)=0\\\\(x+2) (x-3) = 0\\\\x = -2, x = 3\)

Since, The value of x = -2 is not possible (because days are not shown in negative sign).

Hence, The value of x is 3 days.

Answer:

x = -5

Step-by-step explanation:

Given the equation of:

\(\displaystyle{2^x = \dfrac{1}{32}}\)

32 can be written in an exponential form of base 2 as 2⁵ since 2⁵ equals to 32.

\(\displaystyle{2^x = \dfrac{1}{2^5}}\)

Apply the law of exponent where:

\(\displaystyle{\dfrac{1}{a^n} = a^{-n}}\)

Therefore:

\(\displaystyle{2^x = 2^{-5}}\)

We have same base for both sides. Compare and consider the exponents only:

\(\displaystyle{x=-5}\)

Therefore, the value of x is -5.

Step-by-step explanation:

you have to make sure the bases are the same

2 multiplied by itself 5 times equals 32

Tone's new monthly payment is 16.16% higher than his old monthly payment To solve the problem, we need to use the formula for the monthly payment of a mortgage loan:

monthly payment = (loan amount x monthly interest rate) / (1 - (1 + monthly interest rate)^(-n))

where:

loan amount = the amount of the loan

monthly interest rate = the annual interest rate divided by 12

n = the total number of payments (in months)

Let's first find the loan amount at the beginning of the mortgage. We know that Tone paid $9.99 per thousand, so we can set up a proportion:

$9.99 / 1000 = monthly payment / loan amount

Solving for the loan amount, we get:

loan amount = monthly payment / ($9.99 / 1000) = $1000 * (monthly payment / $9.99)

Substituting the given values, we get:

loan amount = $1000 * (monthly payment / $9.99) = $55,000

This means that Tone borrowed $55,000 at the beginning of the mortgage.

Now, let's find the old monthly payment. We know that Tone had a 10.5% adjustable rate mortgage for 30 years, which means he made 12 x 30 = 360 monthly payments. We can use the formula above to solve for the monthly payment:

monthly interest rate = 10.5% / 12 = 0.00875

n = 360

monthly payment = ($\(55,000 x 0.00875) / (1 - (1 + 0.00875)^(-360)\)) = $512.47

Therefore, Tone's old monthly payment was $512.47.

Next, let's find the new monthly payment. We know that Tone will renew his mortgage at 12.5% interest rate, which means the new monthly interest rate is:

monthly interest rate = 12.5% / 12 = 0.01042

We also know that Tone will pay $10.68 per thousand, so we can set up a new proportion:

$10.68 / 1000 = new monthly payment / loan amount

Solving for the new monthly payment, we get:

new monthly payment = $10.68 / ($1000 / $55,000) = $595.40

Therefore, Tone's new monthly payment is $595.40.

Finally, let's find the percent increase in the new monthly payment compared to the old monthly payment. We can use the percent change formula:  

percent increase = ((new value - old value) / old value) x 100%

Substituting the given values, we get:

percent increase = (($595.40 - $512.47) / $512.47) x 100% = 16.16%

Therefore, Tone's new monthly payment is 16.16% higher than his old monthly payment

Emily claims that a tree height of 43 inches is an outlier for the distribution.

What is the 1.5 IQR rule for outliers?

Add 1.5 to the interquartile range (IQR) (a constant used to discern outliers). The third quartile is increased by 1.5 times (IQR). Any figure above this is thought to be an outlier.

The starting and the end of the box in box plot are first and third quartile respectively.

From the given box plot it is clear that, Q₁ = 34  and Q₃ = 38

IQR = Q₃ -  Q₁

IQR = 38 - 34

IQR = 4

According to 1.5x IQR rule for outliers, all the data values lies outside the interval [ Q₁  - 1.5 × IQR , Q₃ + 1.5 × IQR ] are outliers..

Q₃ + 1.5 × IQR = 38 + 1.5(4)

Q₃ + 1.5 × IQR = 38 + 6

Q₃ + 1.5 × IQR = 44

We know that, 43<44.

Since, 43 is not greater than Q₃ + 1.5 × IQR  therefore, 43 is not an outlier and there is no evidence to support the claim.

a) If the letter chosen is a "u," the probability that the guest is from Britain is 1.

b) If the letter chosen is an "h," the probability that the guest is from Britain is 1/2.

a) Let's first find the probability that a randomly chosen guest writes the word with a "u." The probability that a person from the US spells "humor" with a "u" is 0, while the probability that a person from Britain spells "humour" with a "u" is 1. Therefore, the probability that a randomly chosen guest spells the word with a "u" is

(2/3) x 0 + (1/3) x 1 = 1/3

Now, we want to find the probability that the guest is from Britain given that the letter chosen is a "u". We can use Bayes' theorem to find this:

P(Britain|u) = P(u|Britain) x P(Britain) / P(u)

P(u) is the probability that the letter chosen is a "u," which we found to be 1/3. P(u|Britain) is the probability that a person from Britain spells the word with a "u," which is 1. P(Britain) is the probability that a randomly chosen guest is from Britain, which is 1/3. Plugging in these values, we get:

P(Britain|u) = 1 x 1/3 / 1/3 = 1

b) Similarly, we can find the probability that the letter chosen is an "h":

P(h) = P(h|US) x P(US) + P(h|Britain) x P(Britain)

= 0.5 x 2/3 + 1/3 x 1/2

= 1/3

The probability that a person from the US spells the word with an "h" is 0.5, while the probability that a person from Britain spells the word with an "h" is 1/2.

Now, we want to find the probability that the guest is from Britain given that the letter chosen is an "h." Using Bayes' theorem again:

P(Britain|h) = P(h|Britain) x P(Britain) / P(h)

P(h|Britain) is the probability that a person from Britain spells the word with an "h," which is 1/2. P(Britain) is still 1/3. P(h) is the probability that the letter chosen is an "h," which we found to be 1/3. Plugging in these values, we get

P(Britain|h) = 1/2 x 1/3 / 1/3 = 1/2

Answer:

a can be anything, both sides do the same thing

Step-by-step explanation:

If f does not attain a maximum value on [a,b], then the function does not attain a maximum value. The option "f does not attain a minimum value on [a,b]" must be true.

A maximum value is the highest value of a function, that is, the largest y-value of a graph. For example, f(x) = x² has a maximum value of infinity because the parabola opens upwards, and its value keeps increasing infinitely. Therefore, the highest value it attains is infinite.

If f does not attain a maximum value, then there is no highest value, meaning that the value of the function increases indefinitely. In that case, there must not exist a minimum value, since the function keeps rising indefinitely without any upper bound. Hence, f does not attain a minimum value on [a,b].

Option C must be true, which is: O f does not attain a minimum value on [a,b].

Option D is the pair of functions which is not a pair of inverse function.

Explanation

First of, the inverse of a function is a function that reverses the actions of the function. That is, for the inverse function, if we are given f(x), we would be able to obtain x.

The step to finding a function's inverse is to write y instead of f(x). We then rewrite by replacing the y by x and then make y the subject of formula, the y which is a subject of formula now, represents the inverse function, f⁻¹(x).

For each of them, we can get the other one from it.

f(x) = (x + 1)/6

y = (x + 1)/6

x = (y + 1)/6

Cross multiply

6x = y + 1

y = 6x - 1

g(x) = 6x - 1

f(x) = (x - 4)/19

y = (x - 4)/19

x = (y - 4)/19

19x = y - 4

y = 19x + 4

g(x) = 19x + 4

f(x) = x⁵

y = x⁵

x = y⁵

y = 5√x

g(x) = 5√x

Only option D doesn't give the inverse of the other function.

The image of ABC under the translation by 1 unit to the right and 4 units up is the triangle with vertices A', B', and C'.

A triangle is a closed two-dimensional geometric shape with three straight sides and three angles. It is one of the basic shapes in geometry and has been studied since ancient times. To translate a figure by a given vector, you need to move each point of the figure by the same amount and in the same direction as the vector. In this case, we want to translate ABC by a vector of (1, 4), which means we need to move each point of ABC one unit to the right and four units up.

Let's say the coordinates of the points of ABC are:

A = \(\rm (x_1, y_1)\)

B = \(\rm (x_2, y_2)\)

C = \(\rm (x_3, y_3)\)

To translate ABC by the vector (1, 4), we add 1 to each x-coordinate and 4 to each y-coordinate:

A' = \(\rm (x_1 + 1, y_1 + 4)\)   (x₁ + 1, y₁ + 4)

B' = \(\rm (x_2 + 1, y_2 + 4)\)   (x₂ + 1, y₂ + 4)

\(\rm C' = (x_3 + 1, y_3 + 4)\)  (x₃ + 1, y₃ + 4)
