Answer:

-22

Step-by-step explanation:

Let's solve the problem,

→ -3 - {3 - [-3(2 + 4) - (-2)]}

→ -3 - {3 - [-18 + 2]}

→ -3 - {3 + 16}

→ -3 - 19 = -22

So, the answer is -22.

The probability of selecting both defective gadgets out of 100 gadgets is 1/110, which is calculated using the basic concepts of probability theory.

What is a random experiment?

An experiment that is repeated several times and produces more than one possible outcome is called as the random experiment. It contains a well-defined set of values which constitutes a sample space. Eg: Rolling a die, tossing a coin etc.

Calculation of the probability of selecting both gadgets as defective

The total amount of gadgets = 100

Number of defective gadgets = 10

The probability of selecting a defective gadget is 10 / 100 or 1 / 10

Now, the total number of gadgets and defective gadgets are decreased by 1

So, the probability of selecting another gadget as defective is 9 / 99 or 1 / 11

P(E) = P(when two selected gadgets are defective) = 1 / 10 x 1 / 11

P(E) = 1 / 110

Hence, the probability of selecting both defective gadgets is 1/110.

For the occurrence of two events at the same time we will find the least common multiple.

If I have piano lessons on every 7th day and tuba lessons on every 3rd day,

Least common multiple of 3 and 7 will be,

Multiples of 3 = 1 × 3

Multiples of 7 = 1 × 7

Least common multiple (LCM) of 3 and 7 = 3 × 7

Answer:

ik what you ment

this is your answer 45,435,439.87

Step-by-step explanation:

By assuming that both DVD's cost $25 or less, we will reach an absurd. In that way we conclude that at least one of the two DVD's costs over $25.

We know that Isaac bought two DVD's and spent over $50.

Let's define the variables:

Because the cost is over $50 we can write the inequality:

x + y > $50

Here we want to prove that at least one of the two DVD's costed over $25, now let's find an absurd here, let's assume that neither of the DVD's costed over $25, then we can write:

x ≤ $25

y ≤ $25

So we have a set of 3 inequalities:

x + y > $50

x ≤ $25

y ≤ $25

Now, the maximum values that x and y can take are $25, if we use these values in the first inequality we will get:

$25 + $25 > $50

$50 > $50

So this is an absurd, this means that we can't assume that neither of the DVD's costs over $25, then we conclude that at least one of the DVD's costs over $25, which is what we wanted to prove.

Step-by-step explanation:

Hello!

Let's take an example: x > y

The rule that we currently have would state that -x < -y.

Now, let's substitute values for x and y. Say x is 5 and y is -3.

5 is greater than -3 (x > y), but -5 would be less than -3. (-x < -y). Hence the inequality would be true.

We can also take a look at this graphically on a number line. Turning a number negative is simply reflecting it over value 0.

As you can see, flipping the signs would change the values. To keep the inequality accurate, we reverse the inequality sign as well.

3 Answers: Choice A, Choice B, Choice E

=========================================================

Explanation:

We have four copies of x in the original expression. So that accounts for the 4x. In other words, 4x = x+x+x+x. Multiplication is used for repeated addition.

Also, the other terms add to 15+5+15+5 = 20+20 = 40

Therefore, we end up with 4x+40 from choice A.

-----------------------------

Once we get to 4x+40, we can factor out 2 from it like so

4x+40

2*2x + 2*20

2(2x+20) which is choice B

I used the distributive property to factor. That rule is a(b+c) = ab + ac

-------------------------------

Choice C is not one of the answers. We can determine this fairly quickly by noting that the expression in choice C talks about a quadratic, but the original expression given to us is linear.

Choice D is a similar story to choice C.

--------------------------------

Choice E is another answer

This is because we have two copies of (x+15), so that gives 2(x+15)

We also have two copies of (x+5) to get 2(x+5)

37 centimeters is equal to approximately 14.5 inches.

We know that 1 cm is equal to 0.39 inches.

So to convert 37 cm to inches we multiply 37 with 0.39

37×0.39=14.47 inches

The time that it would take for you heart to beat 700,000 times is

8days 2hours 26 mints 40second.

To calculate at this rate of heart to beat 700,000 times we take :

It should be noted that the heart beats in a day = 86400 times

(24 hours = 86400 times)

Takes about 1 hour for a heart to beat  = 3600times

Takes about 15 mints for a heart to beat  = 900times

Takes about 60 sec for a heart to beat  = 60times

Therefore,

the number of days will be given as

= 700000 / 86400

= 8.10 days

=  8days 2hours 26 mints 40second.

Answer:

[tex]1[/tex] and [tex]6[/tex].

Step-by-step explanation:

Let [tex]x[/tex] denote one of the integers. Since the two integers add up to [tex]7[/tex], the other integer would be [tex](7 - x)[/tex].

The sum of the squares of these integers is [tex]37[/tex]. In other words:

[tex]x^{2} + (7 - x)^{2} = 37[/tex].

Expand [tex](7 - x)^{2}[/tex] using binomial expansion. Simplify and rewrite this equation and solve for [tex]x[/tex].

[tex]2\, x^{2} - 14\, x + 12 = 0[/tex].

[tex]x^{2} - 7\, x + 6 = 0[/tex].

Using the quadratic formula or factorization, [tex]x = 1[/tex] or [tex]x = 6[/tex]. Thus, the two integers are [tex]1[/tex] and [tex]6[/tex].

If an interval estimate is said to be constructed at the 90 confidence level, the confidence coefficient would be 0.9.

Confidence level:

Confidence level means the proportion or frequency of acceptable confidence intervals that contain the true value of the unknown parameter.

For example,

A 0% confidence level means you have no faith at all that if you repeated the survey that you would get the same results.

Confidence Coefficient:

Confidence coefficient states the confidence level stated as a proportion, rather than as a percentage.

For example, if you had a confidence level of 99%, the confidence coefficient would be .99.

Given,

Here we know that the confidence level is 90%, now we have to find the confidence coefficient of it.
