Answer:

4

Step-by-step explanation:

It will still be 4 in. tall.  Do you mean that the parameter will remain the same?  You need to specify all constraints when asking a question (in other words: give all the details that you are given -- although I know that a lot of instructors are unnecessarily vague).  If the parameter will remain the same value then we can use the rectangle parameter formula to determine the new value for the height (aka. "length" or "how tall"):

Parameter = Length1 + Length2 + Width1 + Width2

 or

P = 2l + 2w

 so...

P = 2(4) + 2(2) = 8 + 4 = 12

 therefore...

1.   12 = 2(x) + 2(4)

2.   12 = 2x + 8

3.   12 - 8 = 2x + 8 - 8

4.   4 = 2x

5.   4 / 2 = x · 2 / 2

6.  2 = x

x = 2 in.

Answer:

House coordinate = (5, 1)

Library coordinate = (10, 13)

Step-by-step explanation:

Given :

House coordinate = (5, 1)

Library coordinate = (10, 13)

Distance between house snd library :

Distance = sqrt[(x2 - x1)² + (y2 - y1)]

x1 = 5, x2 = 10, y1 = 1, y2 = 13

Distance = sqrt[(10 - 5)² + (13 - 1)²]

Distance = sqrt[(5² + 12²)]

Distance = sqrt(25 +144)

Distance = sqrt(169)

Distance = 13

answer:

x = 5

hope this helped <3 also if wouldn't mind could you pls give me brainliest? (im trying to level up) thanks! :)

Answer:

x=5

Step-by-step explanation:

Multiply 4 and x then multiply 4 and -2.

Which equals 4x-8=12.

Then add 8 on each side (4x-8+8=12+8).

Which equals 4x=20.

Then divide both sides by 4 (4x/4=20/4).

Which equals x=5.

Answer:

(i) 1/21

(ii) 1/10

(iii) Take a look at the explanation: Try this one yourself. I have given you some hints.

Step-by-step explanation:

(i) Two red balls:

To do this, we need to find the total amount of possible choices first. To do this, we multiply 15 by 14. This is our denominator:

15(14) = 210

Now, we need to find the total combinations of red balls. We solve 5 choose 2 for this one.

5 choose 2 = 5(4)/2! = 10

Our numerator is 10. Therefore, our probability is 10/210 = 1/21.

(ii) Two blue balls or two black balls:

To do this, we need to add the probabilities of getting a blue ball with a black ball. (Since there is an "or" sitting there. If there is an "and", we multiply)

So, let's calculate the probability of getting a blue ball first:

Blue:

We use the same denominator as before: 210.

Our numerator is now 6 choose 2, which is:

6 choose 2 = 6(5)/2! = 15.

Now, our fraction is 15/210, BUT, dont simplify, as we will need to add.

Black:

Same steps: denominator is 210, but the numerator is 4 choose 2.

Solving 4 choose 2:

4 choose 2 = 4(3)/2! = 6.

Our numberator is 6.

But, we cant forget to add them!

(15 + 6)/210 is 21/210, which is 1/10.

(iii) I'll let you try this one by yourself. Here is a hint:

Solve for the probability of chooseing a black ball and a red ball. Then, multiply.

Enjoy the process, and I hoped this helped you! (If you have any questions, feel free to ask)

Answer:

= 4x + 9

Step-by-step explanation:

Given f(x) = 2x + 3 and g(x) = –x2 + 5, find ( f o f )(x).

( f o f )(x) = f ( f (x))

   = f (2x + 3)

   = 2(           ) + 3    ... setting up to insert the input

   = 2(2x + 3) + 3

Answer:

%20

Step-by-step explanation:

It is unlikely that the projected rebounds in 15 shots will actually happen.

Total shots fired equals 10.

To find that there were 15 shots total.

Consider S to be the likelihood that your team will rebound and miss a shot.

P(S) = Number of rebounds / Total Number of outcomes

P(S) = 7/15

P(S) = 0.46

Consequently, it is unlikely that the projected rebounds in 15 shots will actually happen.

Thus, it is unlikely that the projected rebounds in 15 shots will actually happen.

Answer:

-1 and -5

Step-by-step explanation:

You must account for negative u values (which the abs nullifies).

So \(5u+15=10\) and \(5u+15=-10\) is what we have to solve for.

As for usual equations, isolate the u variable.

5u + 15 = 10

5u + 15 (-15) = 10 (-15)

5u = -5

\(\frac{5u}{5}=\frac{-5}{1}\)

u = -1

Now you can do the same operation for the other equation and you should get u = -5.

Let's make sure we did it right by replacing u with one of our solutions (-1 or -5).

\(|5(-1)+15| = 10\\10 = 10\)

That's true. What about the other one?

\(|5(-5)+15|=10\\10=10\)

The probability that the book is non-fiction, round to 2 decimal place = 1.72

Based on the given conditions,

A shelf holds 19 different books

8 are fiction and rest non-fiction.

If a shelf holds19 books on her bookshelf and it has 8 fiction books, the number of non-fiction books .

A shelf has will be 19-8 = 11 non- fiction books.

Probability = Expected outcome of event/total outcome.

Our anticipated result will be 11, as we're looking for the expression that captures the likelihood that the book she chooses will be non-fiction (the total non fiction she selected)

The total outcome will be the total number of books

That is, 19.

Probability that she elects non fiction book = 19/11

= 1.72

Therefore,

The probability that the book is non-fiction, round to 2 decimal place = 1.72

As σx (standard deviation) remains unchanged, the value of x alone cannot determine the effect on sample mean. It depends on the value of x relative to the values in original sample and sample size.

If one new person is added to the sample and the standard deviation (σx) remains unchanged, the effect on the sample mean (m) can be determined as follows:

Let's denote the original sample size as n and the sum of the sample values as Σx.

Original sample mean:

m = Σx / n

After adding the new person, the new sample size becomes n + 1, and the sum of the sample values becomes Σx + x_new (x_new represents the value of the new person).

New sample mean:

m' = (Σx + x_new) / (n + 1)

To analyze the effect, we can express the difference in means:

Δm = m' - m = ((Σx + x_new) / (n + 1)) - (Σx / n)

Simplifying this expression, we get:

Δm = (x_new - (Σx / n)) / (n + 1)

Therefore, the effect of adding the new person on the sample mean (m) is determined by the difference between the value of the new person (x_new) and the original mean (Σx / n), divided by the increased sample size (n + 1).

Answer:

n^2 + 2n.

Step-by-step explanation:

n       =       1     2     3     4     5

term t =     3    8     15   24   35

Diffs  =          5    7      9     11

                        2     2     2             - so the nth term contains n^2.

n^2   =       1     4      9    16    25

t - n^2 =    2    4      6     8     10

This is an arithmetic sequence with nth term = 2 + (n-1)2 = 2n

So the nth term of the quadratic sequence = n^2 + 2n.

Answer:

I have no idea

Step-by-step explanation:

The series [infinity] xn n! n = 0 converges for all real values of x.

The given series [infinity] xn n! n = 0 is a power series with terms xn n! n. To determine the values of x for which the series converges, we can use the ratio test.

The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is less than 1, then the series converges. Let's apply the ratio test to the given series:

lim┬(n→∞)⁡〖|(x(n+1)(n+1)!)/(xn n!)|〗

Simplifying the expression:

lim┬(n→∞)⁡〖|(x(n+1))/(xn)| * 1/(n+1)|〗

As n approaches infinity, the ratio x(n+1)/xn approaches x/x = 1. Additionally, the term 1/(n+1) approaches 0. Therefore, the limit simplifies to:

lim┬(n→∞)⁡〖|1 * 0| = 0|〗

Since the limit is less than 1, the ratio test confirms that the given series converges for all real values of x.
