7-4.9t=15+7.6t solve for t

Answers

Answer 1

-0.64 = t That is the answer to your problem

Answer 2

You will try to get t by itself.
Start with adding 4.9t to both sides to get 7=15+12.5t
Then subtract 15 from both sides to get -8=12.5t
Divide both sides by 12.5t so you will get -0.64=t.
Plug this back in to the equation to check your work.
7-4.9(-.64)=10.136
15+7.6(-.64)=10.136

(–0.2b^6)^3(5b) this is the question to be answered

Answers

Final answer:

The simplified form of the expression [tex](-0.2b^{6})^3(5b)[/tex] is [tex]-0.04b^{19}[/tex], obtained through raising to a power and multiplication.

Explanation:

The student's question involves simplifying an algebraic expression by raising a term to a power and then multiplying it by another term. To simplify [tex](-0.2b^{6})^3(5b)[/tex], we must first raise [tex]-0.2b^{6}[/tex] to the third power and then multiply the result by 5b. This will give the answer [tex]-0.04b^{19}[/tex], which can be obtained following the below mentioned steps.

Let's do this step by step:

Raise [tex]-0.2b^{6}[/tex] to the third power: [tex](-0.2)^3[/tex]= −0.008 and [tex](b^{6})^3[/tex]= [tex]b^{18}[/tex]

Multiply the result by 5b: [tex](-0.008)b^{18}*5b[/tex] = [tex](-0.008*5)b^{18+1}[/tex] = [tex]-0.04b^{19}[/tex]

The final simplified expression is [tex]-0.04b^{19}[/tex].

Let f(x) = k(9x − x2) if 0 ≤ x ≤ 9 and f(x) = 0 if x < 0 or x > 9. (a) for what value of k is f a probability density function?

Answers

We require

[tex]\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx=1[/tex]

Since

[tex]f(x)=\begin{cases}k(9x-x^2)&\text{for }0\le x\le9\\0&\text{otherwise}\end{cases}[/tex]

the integral above reduces to

[tex]\displaystyle\int_0^9 k(9x-x^2)\,\mathrm dx=k\left(\dfrac92x^2-\dfrac13x^3\right)\bigg|_{x=0}^{x=9}=\dfrac{243k}2=1[/tex]
[tex]\implies k=\dfrac2{243}[/tex]

Final answer:

To find the value of k that makes f(x) a probability density function, we need to satisfy two conditions: f(x) must be non-negative for all x and the total area under the curve of f(x) must equal 1. Solving the integral of the function f(x) = k(9x - x^2) from x = 0 to x = 9, we find that the value of k that satisfies these conditions is approximately 0.0696.

Explanation:

In order for the function f(x) to be a probability density function, it must satisfy two conditions:

The function must be non-negative for all values of x.

The total area under the curve of the function must be equal to 1.

Let's analyze the function f(x) = k(9x - x^2) for 0 ≤ x ≤ 9 and f(x) = 0 for x < 0 or x > 9:

If 0 ≤ x ≤ 9, the function f(x) is given by f(x) = k(9x - x^2).The function f(x) is non-negative in the interval [0, 9] if k(9x - x^2) ≥ 0. This is true when k > 0.To find the value of k that makes the total area under the curve equal to 1, we need to integrate the function f(x) = k(9x - x^2) from x = 0 to x = 9 and set it equal to 1:∫09 k(9x - x^2) dx = 1Simplifying the integral gives us k(405 - 364.5) = 1Solving for k, we get k ≈ 0.0696 (rounded to four decimal places).

Therefore, the value of k that makes f(x) a probability density function is approximately 0.0696.

fInd the missing term in the following geometric sequence. 4, __, 500

Answers

The answer is 4, 20,100, 500

Answer: The missing term in the given geometric sequence is 20√5 or -20√5.

Step-by-step explanation: We are given to find the missing term in the following geometric sequence :

4, ?, 500, . . .

Let b represents the missing term.

Since the given sequence is a geometric one, so there common ratio r such that

[tex]\dfrac{b}{4}=\dfrac{500}{b}=r\\\\\\\Rightarrow \dfrac{b}{4}=\dfrac{500}{b}\\\\\Rightarrow b^2=4\times500\\\\\Rightarrow b^2=2000\\\\\Rightarrow b=\pm\sqrt{2000}\\\\\Rightarrow b=\pm20\sqrt{5}.[/tex]

Thus, the missing term in the given geometric sequence is 20√5 or -20√5.

Richard borrowed $1,250 for two years at 14% a year under an add-on plan. He repaid the loan, including interest, in 24 equal payments. How much was each payment?

Answers

First you need to use the compound interest formula to work out the amount of money he had after those two years. To do this you have to make a multiplier for the 14% and you have to put the number of years to the power of the multiplier and of course you need to times the original amount by the multiplier:
(100+14)/100 = 1.14 (making the multiplier)

1250*(1.14)^2 = 1624.5

Then you divide the 1624.5 by 24 to get the equal payments:
1624.5/24 = $67.6875 (rounded to $67.69)

Richard made payments of $67.69 24 times to pay off the loan he had taken out.

Hope this helps! :)

$1,250 compounded 14% in two years $1,624.50/24 = $67.6875 monthly payment.

write the following comparison as a ratio reduced to lowest terms.

114 hours to 13 days

Answers

Final answer:

To write the comparison as a ratio reduced to lowest terms, we need to convert both the hours and the days to a common unit of time. There are 24 hours in a day, so we can convert 13 days to hours by multiplying 13 by 24: 13 days x 24 hours/day = 312 hours. Now, the comparison is 114 hours to 312 hours. We can simplify this ratio by dividing both numbers by their greatest common factor, which is 6. 114 ÷ 6 = 19, and 312 ÷ 6 = 52. Therefore, the simplified ratio is 19:52.

People drive, on average, 11,900 miles per year. About how many miles each week is that

Answers

Final answer:

To calculate the average weekly driving mileage based on an annual average of 11,900 miles, divide the total miles by 52 weeks, resulting in approximately 228.85 miles driven per week.

Explanation:

The question asks us to calculate how many miles are driven each week if an average person drives 11,900 miles per year. To find the weekly mileage, we can divide the total annual miles by the number of weeks in a year. Since there are 52 weeks in a year, we would perform the following calculation:

Divide 11,900 by 52.11,900 miles \/ 52 weeks = 228.85 miles per week.

Therefore, on average, a person drives approximately 228.85 miles each week.

You drove at 55mph for 4.5 hours. Which of the following equations will tell you how far you drove? A: d=(55)(4.5) B: 55=r(4.5) C: 4.5=55t D: 4.5=r(55)

Answers

A. 55mph x 4.5hrs which makes since because mph is miles per hour, so I drove 55miles every hour.

Answer : The correct equation will be, (A) [tex]d=(55)\times (4.5)[/tex]

Step-by-step explanation :

As we are given that:

Speed = 55 mph

Time = 4.5 hr

As we know that:

[tex]Distance=Speed\times Time[/tex]

So,

[tex]Distance=55mph\times 4.5hr[/tex]

[tex]Distance=55\times 4.5[/tex]

or,

[tex]d=(55)\times (4.5)[/tex]

Thus, the correct equation will be, (A) [tex]d=(55)\times (4.5)[/tex]

The units after conversion are:

48 c = 12 qt

96 oz > 5 lb

6 yd, 1 ft = 19 ft

6 1/2 lb = 104 oz

We have,

To convert 48 cups to quarts, we know that there are 4 cups in 1 quart. Therefore, dividing 48 by 4 gives us the number of quarts.

48 cups / 4 cups/quart = 12 quarts

To compare 96 ounces to 5 pounds, we need to convert one of the units so that they are in the same unit of measurement.

Since there are 16 ounces in 1 pound, we can convert 5 pounds to ounces.

5 pounds x 16 ounces/pound = 80 ounces

Now we can compare 96 ounces and 80 ounces.

Since 96 is greater than 80.

To convert 6 yards and 1 foot to feet, we know that there are 3 feet in 1 yard.

Therefore, we can convert the yards to feet and add the 1 foot.

6 yards x 3 feet/yard = 18 feet

18 feet + 1 foot = 19 feet

To convert 6 1/2 pounds to ounces, we know that there are 16 ounces in 1 pound. We can convert the whole number part and the fraction part separately and then add them together.

6 pounds x 16 ounces/pound

= 96 ounces

Now let's convert the fraction:

1/2 pound x 16 ounces/pound = 8 ounces

Adding the two parts together:

96 ounces + 8 ounces = 104 ounces

Thus,

The units after conversion are:

48 c = 12 qt

96 oz > 5 lb

6 yd, 1 ft = 19 ft

When a particular machine is functioning properly, 80% of the items produced are non-defective. if three items are examined, what is the probability that one is defective? use the binomial probability function to answer this question?

Answers

15 percent there u go have a good ay

Answer:

The probability is 38.4%

Step-by-step explanation: Here we have two posibilites for each of the 3 items, it is defective or it is not.

Where the probability that the item is defective is equal to 20% (or 0.2 in decimal form)

Now, if only one is defective, this means that the other two are not, so the probabilites (at random) are 20%, 80% and 80%.

Then the joint probability, equal to the product of those 3 probabilities, is:

p = 0.2*0.8*0.8 = 0.128

But we have 3 posible permutations (in which different options are the deffective one) so the probability is 3 times that number:

P = 3p = 3*0.128 = 0.384

So the probbility, in percentage form, is 38.4%
