I really need help.​

Answers

A submarine descends to a depth of 600 feet below the surface in 10 minutes. At this rate, what integer represents the change, in feet, of the submarine's position after one minute?

First you need to list what you're given.

A submarine descends to a depth of 600 ft below the surface in 10 minutes. The question is asking for the change of the submarine's position after one minute. This can be represented as fractions in terms of [tex]\frac{distance}{time}[/tex].

[tex]\frac{600}{10} = \frac{x}{1}[/tex]

You're looking for the value of x. First you need to cross-multiply.

[tex]600 \times 1 = 10 \times x\\600=10x[/tex]

Since you're looking for x alone, you need to divide both sides by 10. This will eliminate the 10 since x is being multiplied by 10, and 10 divided by 10 is 1, making it 1x or x.

[tex]\frac{600}{10} = \frac{10x}{10}[/tex]

[tex]60=x[/tex]

That means the submarine is descending at a rate of 60 feet per minute, which can be represented as -60.

If you're looking for the submarine's position after one minute, all you have to do is subtract 60.

600 feet below surface is represented as -600.

[tex]-600-60=-660[/tex]

The submarine's position after one minute is 660 feet below surface(-660).

The mean life of a television set is 138 months with a variance of 324. If a sample of 83 televisions is randomly selected, what is the probability that the sample mean would be less than 143.4 months

Answers

Answer: 0.9968

Step-by-step explanation:

Let [tex]\overline{X}[/tex] be the sample mean life of television.

Given: [tex]\mu=138,\ \ \ \sigma^2=324\Rightarrow\ \sigma=\sqrt{324}=18,\ \ \ , n=83[/tex]

The probability that the sample mean would be less than 143.4 months will be :

[tex]P(\overline{X}<143.4)=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}<\dfrac{143.4-138}{\dfrac{18}{\sqrt{83}}})\\\\=P(Z<2.733)=0.9969\ \ \ [\text{By p-value table}][/tex]

hence, the required probability = 0.9968

(3x + 3)(3x + 8)
PLEASE HELPPP:)

Answers

Answer:

9x^2+33x+24

Step-by-step explanation:

The factors (3x + 3)(3x + 8) can be expressed as a trinomial 9x² + 33x + 24.

What is the expression?

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

To express (3x + 3)(3x + 8) as a trinomial, we can use the distributive property and FOIL (First, Outer, Inner, Last) method.

First, we multiply the first term of each binomial (3x) with the first term of the other binomial (3x), which gives us (3x)(3x) = 9x².

Next, we multiply the first term of one binomial (3x) with the second term of the other binomial (8), which gives us (3x)(8) = 24x.

Then we multiply the second term of one binomial (3) with the first term of the other binomial (3x) , which gives us (3)(3x) = 9x

Finally, we multiply the second term of each binomial (3) with the second term of the other binomial (8) , which gives us (3)(8) = 24

Now we add all the products to get the trinomial

9x² + 24x + 9x + 24 = 9x² + 33x + 24

Therefore, (3x + 3)(3x + 8) can be expressed as a trinomial 9x² + 33x + 24.

Answer:

  equations: q+n = 103; 0.05n +0.25q = 8.75

  solution: q=18; n=85

Step-by-step explanation:

Write one equation for the number of coins:

  q+n=103.

Write another equation for the value of the coins:

  0.05n +0.25q = 8.75.

It is often convenient to substitute for the lower value, here, using n = 103-q. This results in an equation for q with positive coefficients.

  0.05(103 -q) +0.25q = 8.75

  5.15 +0.20q = 8.75

  0.20q = 3.60

  q = 18

  n = 103 -18

  n = 85

Hope I helped :)

Answer:

(see below)

Step-by-step explanation:

12³ × 11³ is NOT equivalent to (12 × 11)[tex]^{3(3)}[/tex] because:

1) 12³ and 11³ don't have the same bases. They have to both have a base of 11 or of 12.

2) 12³ × 11³ and (12 × 11)[tex]^{3(3)}[/tex] are different because (12 × 11)[tex]^{3(3)}[/tex] is a whole different number altogether. Here's why:

12³ × 11³ = 1728 × 1331

              = 2,299,968

(12 × 11)[tex]^{3(3)}[/tex] = [tex](132)^{9}[/tex]

                  = 1.216649217 × [tex]10^{19}[/tex]

However, (12 × 11)³ would be equivalent to 12³ × 11³.

(12 × 11)³ = (132)³

               = 2,299,968

Whenever you divide two fractions you rewrite it switching the division sign for multiplication and writing the reciprocal of the second fraction.

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

5/8 of the pizza is equally shared between two people.

The fraction of the original pizza that each person receives is 5/16 of the pizza.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Amount of pizza = 5/8

Equally shared between two people:

= 5/8 ÷ 2

= 5/(8x2)

= 5/16

This means that the fraction of the original pizza that each person receives is  5/16 of the pizza.

Thus,

5/8 of the pizza is equally shared between two people.

The fraction of the original pizza that each person receives is  5/16 of the pizza.
