The difference between the greatest and the least mixed numbers is 9.87 - 6.0789 ≈ 3.7911.

The three digits different from {1, 2, 3, 4, 5} can be chosen from {0, 6, 7, 8, 9}.

The greatest mixed number is formed by placing the largest digit as the whole number and the remaining two digits as the fraction in descending order, i.e., 9 87/100 or 9.87.

The smallest mixed number is formed by placing the smallest non-zero digit as the whole number and the remaining two digits as the fraction in ascending order, i.e., 6 07/90 or 6.0789.

Answer:

  $2496

Step-by-step explanation:

You want to know the cost of carpeting a 18 ft by 24 ft room with carpet that costs $52 per square yard.

The dimensions of the room in yards are (18 ft)/(3 ft/yd) = 6 yd, by (24 ft)/(3 ft/yd) = 8 yd.

In square yards, the area is ...

  (6 yd)(8 yd) = 48 yd²

The cost of one square yard of carpet is $52, so the cost of 48 square yards will be 48 times as much.

  (48 yd²)($52/yd²) = $(48·52) = $2496

The total price to carpet the floor is $2496.

__

Additional comment

We're reluctant to call this the total price, as there are usually additional charges for tax, carpet pad, delivery, installation, removal and disposal of old flooring, and possibly additional materials such as tack strips or thresholds. Repairing mold or water damage, or leveling the floor, can also add cost.

Step-by-step explanation:

To determine whether the earlier measure of one variable is associated with the later measure of the other variable, we can calculate the cross-lag correlation between these two variables. This will give us a measure of the strength and direction of the relationship between the two variables.

If the cross-lag correlation between aggression in third grade and tv violence in 13th grade is positive and statistically significant, it would suggest that there is a positive relationship between the two variables, meaning that higher levels of aggression in third grade are associated with higher levels of tv violence in 13th grade.

On the other hand, if the cross-lag correlation is negative and statistically significant, it would suggest that there is a negative relationship between the two variables, meaning that higher levels of aggression in third grade are associated with lower levels of tv violence in 13th grade.

Similarly, we can also calculate the cross-lag correlation between tv violence in third grade and aggression in 13th grade to determine whether the earlier measure of one variable (tv violence in third grade) is associated with the later measure of the other variable (aggression in 13th grade).

By calculating both cross-lag correlations, we can address the directionality problem and establish temporal precedence between the two variables. This helps us understand the nature of the relationship between aggression and tv violence over time and how it may change as individuals age.

Answer:

x>_-1

Step-by-step explanation:

x is such that x is greater or equal to -1

As x tends to negative one from the left, the value of f(x) tends to positive infinity. As x → -1⁻, f(x) → ∞.

In Mathematics and Geometry, the vertical asymptote of a function simply refers to the value of x (x-value) which makes its denominator equal to zero (0).

By critically observing the graph of this rational function f(x) shown below, we can logically deduce that its vertical asymptote is at x = -1 and x = 2, and its horizontal asymptote is at y = 3.

In this context, we can logically deduce that the value of f(x) tends towards positive infinity, as x tends to negative one from the left;

As x → -1⁻, f(x) → ∞.

Answer:

infinite number of solutions

Step-by-step explanation:

\(\frac{4}{5}\) (x + 9) - \(\frac{1}{5}\) x = \(\frac{3}{5}\) (x + 12)

multiply through by 5 to clear the fractions

4(x + 9) - x = 3(x + 12) ← distribute parenthesis on both sides

4x + 36 - x = 3x + 36

3x + 36 = 3x + 36

since both sides are the same then any value of x will make the equation true.

Thus there are an infinite number of solutions

The time Jack left Santa Clara is 1 : 55 pm

A word problem in math is a math question written as one sentence or more. These statements are interpreted into mathematical equation or expression.

The time for Jack to walk to lose Altos is 25 min and he uses another 25mins to work to Palo alto.

Therefore, the total time he spent is

25mins + 25 mins = 50 mins

He arrived Palo at 2 :45 pm, therefore the time he left Santa Clare will be ;

2:45 pm = 14 :45

The probability that both events B and C will occur is:

P(B and C) = 9/20

Probability is the likelihood of an event to occur. It is expressed as a number in the range from 0 to 1.

The probability of an impossible event is 0, that of an event that is certain to occur is 1.

We have:

The probability that event B will occur, P(B) = 3/4

The probability that event C will occur, P(C) = 3/5

The probability that both events B and C will occur is:

P(B and C) = P(B) × P(C)

P(B and C) = 3/4 × 3/5

1. 10 to the 3rd power will look like this: 10 x 10 x 10 (multiplying 10 three times)

10 x 10 x 10 is 1000.

Then you multiply 1000 by 5.24 like a regular problem, which will equal 5,240.

There are 3 zeroes so you shift the decimal 3 times.

2. 10 to the second power is 10 x 10. 10x10 is 100.

524,000 divided by 100 is 5240. It’s similar to LOSING two zeroes because you’re DIVIDING.

In the two expressions, the powers of 10 are used to express the numbers in a more compact and manageable form.

To convert \(5.24 * 10^3\) to standard form:

Multiply 5.24 by 1000 (since \(10^3\) = 1000).

5.24 x 1000 = 5240

Therefore, 5.24 x \(10^3\) = 5240

524,000 divided by\(10^2\) is also using the concept of powers of 10.

To convert 524,000 divided by \(10^2\) to standard form:\(10^2\)

Divide 524,000 by 100 (since  = 100).

524,000 ÷ 100 = 5,240

Therefore, 524,000 divided by\(10^2\) equals 5,240.

The table represent a linear function. The equation to show the relationship between the number of days, x and the amount of hay a cow eat is as follows:

using slope intercept form,

y = mx + b

where

Therefore, let's find the slope using (10, 250) and (20, 500).

m = 500 - 250 / 20 - 10

m = 250 / 10

m = 25

The y-intercept of the equation can be found as follows:

using (10, 250)

y = 25x + b

250 = 25(10) + b

b = 250 - 250

b = 0

%, a relative figure signifying hundredths of any amount. Since one percent (symbolised as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified. percentage. Mathematical percentile is a related topic.

Sam collects $150.00 each day for 6 days, so the total amount he collects is:

$150.00/day x 6 days = $900.00

The shelter will use 35% of the money he collects to buy pet food. To find out how much money will be used to buy pet food, we can multiply the total amount Sam collects by 35% (or 0.35):

$900.00 x 0.35 = $315.00

So, $315.00 of the money that Sam collects will be used to buy pet food. To find out how much money will be used to buy cleaning supplies, we can subtract the amount used to buy pet food from the total amount collected:

$900.00 - $315.00 = $585.00

Continuous compounding equation:

Now find the time t for the balance to grow to $51806.67:

The time required is about 9 years.

Answer:

9 years

Step-by-step explanation:

Continuous Compounding Formula

\(\large \text{$ \sf A=Pe^{rt} $}\)

where:

Given values:

Substitute the given values into the formula and solve for r to find the annual interest rate:

\(\implies \sf 39786.15=36000 \cdot e^{2.5r}\)

\(\implies \sf \dfrac{39786.15}{36000}= e^{2.5r}\)

\(\implies \sf \ln \left(\dfrac{39786.15}{36000}\right)=\ln e^{2.5r}\)

\(\implies \sf \ln \left(\dfrac{39786.15}{36000}\right)=2.5r\)

\(\implies \sf \dfrac{1}{2.5}\ln \left(\dfrac{39786.15}{36000}\right)=r\)

\(\implies \sf r=\dfrac{2}{5}\ln \left(\dfrac{39786.15}{36000}\right)\)

\(\implies \sf r=0.03999996933...\)

\(\implies \sf r=0.04\;(2\;d.p.)\)

Therefore, the annual interest rate is 0.04 = 4%.

To calculate how many years it will take for $36,000 to grow to $51,806.67, substitute the values into the formula and solve for t:

\(\implies \sf 51806.67=36000 \cdot e^{0.04t}\)

\(\implies \sf \dfrac{51806.67}{36000}= e^{0.04t}\)

\(\implies \sf \ln\left(\dfrac{51806.67}{36000}\right)= \ln e^{0.04t}\)

\(\implies \sf \ln\left(\dfrac{51806.67}{36000}\right)= 0.04t\)

\(\implies \sf \dfrac{\ln\left(\dfrac{51806.67}{36000}\right)}{0.04}=t\)

\(\implies \sf t=9.10 \; (2\;d.p.)\)

Therefore, it will take about 9 years for $36,000 to grow to $51,806,67.
