When marla rounded 19.95to the nearest tenth, she found the number changed to 20.is this correct

Answers

Answer 1

Answer: Yes, Marla is correct.

Answer 2

Answer: yes your answer is correct

Answer:

The statements that best describes its construction is:

There is one possible triangle with these side lengths.

Step-by-step explanation:

We know that with the help of three given angle measures infinite number of triangles could be constructed with different side lengths and with the help of three gives side lengths a unique triangle is constructed.

Here we are given three side lengths as:

8 centimeters, 13 centimeters, 15 centimeters.

This means that there is only one such triangle possible.

I am not completely sure but I would think it would be the second statement. Hopes this helps.

Kn + 4f = 9v
solve for n

Answers

Answer:

n=(9v-4f)/k

Step-by-step explanation:

kn+4f=9v

kn=9v-4f

n=(9v-4f)/k

Answer:

n = (-4f + 9v) ÷ k

Step-by-step explanation:

All you have to do is... flip the equation

Give me 3 ratios that are equal to 40/50 75/100 and 21/18

Answers

Three ratios that are equal to 40/50, 75/100, and 21/18 are 4/5, 3/4, and 7/6. The question is essentially asking you to simplify fractions. For example, 8/10 can also be represented as the ratio 8:10. This fraction can be simplified to 4/5, and the ratio 4:5 is the same as the ratio 8:10.

Is it possible to square root a negative number?

Answers

No because a negative times a negative will be positive and it will not equal a negative number. the square root cannot be one negative and one positive because that is against the definition of a square root.

No because you had no number which were negative after you squared. if you do every number goes back positive after you squared it i think.

Jake had a bag of 50 beads, of which some are red and some are the remaining are yellow. Jake randomly pulls out a bead from the bag, , records the color, and replaces it in the bag. Jake has already recorded 6 red and 9 yellow beads. Based on the results, what is most likely the number of red beads in the bag?

Answers

Most likely the numbers of red beads in the bag are 20.

Let us consider there are x red beads and (50-x) yellow beads.

So, as given in the question, Jake pulls a total of 15 beads(6 red and 9 yellow).

So, P(r)=ed bead probability $=(6)/(15)$

and yellow bead probability $=(9)/(15)$

Now, the total number of red bead $=P(r)*50$

$=(6)/(15)*50=(300)/(15) =20$

Hence, the number of red beads in the bag is most likely to be 20.

What is probability explain?

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.

How to calculate probability?

The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes.

What are some examples of probability?

Example: toss a coin 100 times, how many Heads will come up? Probability says that heads have a ½ chance, so we can expect 50 Heads. But when we actually try it we might get 48 heads, or 55 heads ... or anything really, but in most cases it will be a number near 50.

This is probability. Roughly 40% of the beads are red if data is correct. 20 is 40% of 50. So 20 is the answer/
