Answer:

1.0 x 10^-50

Step-by-step explanation:

k(t) = 10^-5t

k(10) = 10^-5(10)

k(10) = 10^-50

k(10) = 1/(10^50)

k(10) = 1.0 x 10^-50

A cabinet shop wants to determine the effect of adhesive brands on the bonding of veneer to cabinets. The shop divides the cabin

vodomira [7]

Answer:

A. Randomized experiment.

Seee explanation below.

Step-by-step explanation:

Previous concepts

In a Randomized experiment the results can be use to establish causal inferences about means of control. and present two important characteristics:

a) "the independent or explanatory variable is controlled by direct manipulation.

b) "All other sources of variability are controlled by chance".

An observational study is an empirical but is nonexperimental investigation in order to see the effects caused by an specific treatment.

Solution to the problem

For this case we want to determine the effect of adhesive brands on the bonding of veneer to cabinets.

The experiment is conducted with 6 different groups defined with different adhesive and all the groups are the same except by the type of brand for the adhesive used.

So on this case we see that the variable of interest is controlled with direct manipulation with the creation of the 6 groups. And we have that all the the others sources of variability are controlled by chance since all the groups are identical except by the brand type.

So for this case the correct answer would be:

A. Randomized experiment.

A bag has 3 red marbles, 2 blue, 4 greens and 1 yellow. What is the probability of pulling a blue, putting it back

Tomtit [17]

Answer: 2/25

Step-by-step explanation: Since we are replacing the marbles, these two events are independent which means that the outcome of the first does not affect the outcome of the second.

First find the probability of selecting a blue marble.

There are 2 favorable outcomes, the blue marbles,

and 10 possible outcomes, all the marbles in the bag.

So the probability of selecting a blue marble is 2/10 or 1/5.

Always reduce when finding probability

Now we find the probability of selecting a green marble.

There are 4 green marbles and 10 total so the probability of

selecting a green marble is 4/10 or 2/5.

Now we multiply the probabilities.

So we have 1/5 x 2/5 or 2/25.

Answer:

You were correct.

Step-by-step explanation:

If the input to the function y = 4x - 3 is 2 Then

y = 4 * 2 - 3

= 8 - 3

= 5

HELP ME!!! I've been stuck!

Olin [163]

Answer:

You have to fill the blank squares to complete the table.

See the figure attached and the explantion below.

Explanation:

The figure attached shows the three squares that you have to fill to complete the table to summarize the different theorems to prove triangles are congruent.

1. SAS

SAS stands for Side Angle Side. That means that whenever two sides and the included angle on one triangle are congruent to two sides and the included angle of another triangle, then those two triangles are congruent.

Thick marks are used to mark the corrsponding parts, sides or angles that are congruent. That is why the two triangles to the first triangles on the image (on the upper square to the right) are marked:

One thick straight mark for two sides that are congruent
Two thick straight marks for the other two sides that are congruent
On thick curved mark for the two angles that are congruent

In that way, the figures show two triangles, with two congruent sides and the included angle congruent, to prove that the two triangles are congruent by the SAS theorem.

2. ASA

ASA stands for Angle Side Angle.

The ASA congruency theorem states that if two angles of a triangle and the included side are congruent, then the two triangles are congruent.

Thus you have to add the legend "Two congruent angles with and included side", which means that if the two angles and the included side on one triangle are congruent to two angles and the included side of other triangles, then both triangles are congruent.

The rule to mark the sides and angles that are congruent is with the use of thick marks. This is how it was done in the drawing of the two triangles in the lower right square:

One thick straight mark for two sides that are congruent
One thick curved mark for two angles that are congruent
Two thick curved marks for the other two angles that are congruent
