A testable question is one that requires the answer to be acquired by means of experimentation.

Instead of asking, "Which planet is the most interesting to study?" you could ask about the conditions that a planet has which are considered subjects of interest.

Also, instead of asking, "What happens if you do not eat breakfast?" you could ask about how the body is affected when we skip breakfast. This can be tested in an experiment that checks the body's functions when breakfast isn't eaten.

The probability that exactly one of the three vcrs is defective is 0.1354

x = total number of trials = 3 VCRs

x = number of successes = number of defective VCRs = 1

n- x = 3 -1 = 2

p = P(success) = 0.05

q = P(failure) = 1 -p = 1 – 0.05 = 0.095

In this question we are applying binomial distribution strategy: it is always applied to find the probability that an outcome will occur x times in n performances or experiment.

P (x = 1) = 3C1 (0.05)1 (0.95)2

= 3 (0.05) (0.9025)

= 0.1354

Therefore, the probability of exactly one of the three VCRs being a defective one is 0.1354

Answer:

  12 5/6 inches

Step-by-step explanation:

You want to find the value of L when S=12 1/2, using the formula S = 3L -26.

You can substitute for S in the formula before or after you solve for L. Here, we'll solve for L first:

  S +26 = 3L . . . . add 26 to both sides

  (S +26)/3 = L . . . . divide both sides by 3

Substituting 12 1/2 for S, this becomes ...

  L = (12 1/2 +26)/3 = (38 1/2)/3 = (77/2)/3 = 77/6 = 12 5/6

A stem and leaf plot is a table used to display data. The 'stem' is shown on the left side of the table and shows the first digit or digits of data values. The 'leaf' is shown on the right side of the table and shows the last digit of the data value.

A stem and leaf plot displays numerical data by splitting each data point into a "leaf" (usually the last digit) and a "stem" (the leading digit or digits).

Split each data point into a stem and a leaf. The stem is everything before the final digit, and the leaf is the final digit. Write the stems in a vertical column and don't skip stems just because they don't have any data.

Answer:

Step-by-step explanation:

She gets 21$ for 6 hours of work, while the amount of tips is varied.

Answer: it would be A

Step-by-step explanation:

the negations of the hypothesis and conclusion for the given conditional statement are:

not P = "The sum of the interior angle measures of a polygon is not 180°"

not Q = "The polygon is not a triangle"

For two defined propositions P and Q, we define a conditional statement as a sentence of the form:

If P, then Q.

Particularly in this case, P is called the hypothesis and Q is called the conclusion of the conditional statement.

For the given one:

"If the sum of the interior angle measures of a polygon is 180, then the polygon is a triangle."

We will have that the hypothesis is:

The sum of the interior angle measures of a polygon is 180°

The conclusion will be:

The poñyogn is a triangle.

Now we want to negate these two, it is really simple, for the hypothesis we will have that the sum of the interior angles can be any number but 180°, then we can write the negation as:

"The sum of the interior angle measures of a polygon is not 180°

Similar for the conclusion, we just need to state that the polygon is not a triangle, we will get:

"The polygon is not a triangle"

Then the negations of the hypothesis and conclusion for the given conditional statement are:

not P = "The sum of the interior angle measures of a polygon is not 180°"

not Q = "The polygon is not a triangle"

What is Symbolic notation?

Symbolic notation is a way of representing the counting numbers by writing a simple symbol.

Now,

For the false statement we use the symbol ( ~ ).

If in the statement the word ''or'' is present then we use the symbol ''∧'' and for the word ''and'' we use the symbol ''∨''.

Hence,

For the statement;

a. Atlanta is the capital of Georgia, or there are 3 feet in a yard.

Both are truth and with the word ''or'', then the symbolic notation,

⇒ p ∧ q

For the statement;

b. Atlanta is the capital of Georgia and there are not 3 feet in a yard.

One statement is truth and second is false , then the symbolic notation,

⇒ p ∨ ~ q

For the statement;

c. Atlanta is not the capital of Georgia, or there are 3 feet in a yard.

First statement is false and second is truth , then the symbolic notation,

⇒ ~ p ∧ q

For the statement;

well, for the piece-wise function, we'd like to know f(-2), or namely what is f(x) when x = -2?

well, f(x) is 2 for x = -1

f(x) is 4 for x > -1

keeping in mind that in the negative side of the number line, the closer to 0, the larger, thus -1 is much larger than -1,000, so  hmmm -2 is farther from 0 than -1 is, so -1 is larger than -2, so when x = -2, x < -1, and the function that applies when x < -1 is -(x+1)² + 4, so then

From the given information:

The price of eight 4.23 ounce juice boxes is $2.39. we should always know that: 1 Gallon = 128 Ounces and 1 juice boxes = 4.23 ounce

So, juice boxes per gallon = 128/4.23 = 30.26

Answer:

163 degrees

Step-by-step explanation:

163 degrees is equal to y

Z = x

The measure of angle y is 163° and the measure of angle x and z is 17 degrees.

Given that:

Two lines are intersected with each other.

It is required to find the measure of angles x, y, and z.

The angles formed on the opposite side of the intersecting line are called vertical angles.

Also, by the Vertical Angles Theorem, the vertical angles formed are always equal.

Here, y is vertical to the given measure of 163°.

So, y = 163°.

Now, x and y are the angles formed along a line.

So, they are linear pair of angles.

Linear pair of angles are supplementary.

So, x + y = 180

x = 180 - 163

  = 17°

Also, x and z are vertical angles.

So, z = 17°

Hence, x = 17°, y = 163°, and z = 17°.
