Answer:

28,130

Step-by-step explanation:

18,942+9188=28,130

Answer:

28,130(B)

Step-by-step explanation:

So, this is just adding one car by a different car

Or could be looked at as:

18,942+9,188

So lets go from right to left, to find the answer

8+2=10

So we know the ones place is 0.

Next we have the tens place, 8+4+(ten from last number)=13

So know we got: 30.

This gets rid of answer A.

Next we have the hundreds place, 1+9+(hundred from last number) = 11

So know we got: 130

Next we have the thousands, which is 9+8+(thousand from last number) = 18

So now we have 8,130

Well, we already get our answer from this. Since it uliminates C and D, in addition to A. With only B left.

But if we go further:

Next we have the ten thousands, which is 1+(ten thousands from last number)=2

So now we have 28,130

This is our answer

Hope this helps! ;)

Answer: A

Step-by-step explanation: The only one that’s not included in the pattern

Answer:

answer a.

Step-by-step explanation:

You can see that the shaded parts are moving counterclockwise (I think) so if you continue the pattern then you will get A.

Answer:

Plug your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle!

Problem 44:

Because there are 5 terms in the sequence, with each term getting multiplied by 3 having the first term be 3, this equates to the sigma notation [tex]\[ \sum_{n=1}^{5} 3^{n}\][/tex].

Problem 45:

Because there are 5 terms in the sequence, with each term getting multiplied by 1/2 having the first term be 80, this equates to the sigma notation [tex]\[ \sum_{n=1}^{5} 80(\frac{1}{2})^{n-1}\][/tex].

Answer:

  44. sum[n=1..5](3^n)

  45. sum[n=0..3](80·2^-n)

Step-by-step explanation:

The summation symbol is used to collapse all of the plus signs. The argument of the summation symbol is the general term of the series. These are both geometric series, so the general term can be written in the form ...

  an = a1·r^(n-1)

where a1 is the first term and r is the common ratio.

The "-1" can be removed from the exponent if the summation starts with n=0 instead of n=1. Sometimes the multiplication by a1 can be accomplished by adjusting the exponent of the exponential term.

__

49. The first term is 3 and the common ratio is 3, so the general term is ...

  an = 3·3^(n-1) = 3^n . . . for n starting at 1

There are 5 terms in this series, so it can be written as ...

  [tex]\displaystyle S=\sum_{n=1}^5{3^n}[/tex]

__

50. The first term is 80 and the common ratio is 1/2, or 2^-1. Then the general term is ...

  an = 80·(2^-1)^(n-1) . . . for n starting at 1

If we let start at 0, then the general term is ...

  an = 80·2^-n

There are 4 terms in the series, so it can be written as ...

  [tex]\displaystyle S=\sum_{n=0}^3{(80\cdot2^{-n})}[/tex]

Answer:

(-18, 9)

Step-by-step explanation:

If a coordinate A(x,y) is dilated by a factor of k, the new coordinates will be expressed as;

A' = (kx, ky)

A' = A (kx, ky)

Given the following

k = 1/3

A' = (-6, 3)

Substitute

(-6, 3) = 1/3(x, y)

Cross multiply

3(-6, 3) = (x, y)

(x, y) = (3(-6), 3(3))

(x, y) = (-18, 9)

Hence the coordinate prior to dilation is (-18, 9)

Answer:

0.2776 = 27.76% probability that fewer than 40% of the customers in the sample purchased the service contract.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

45% of these customers also purchased the extended service contract.

This means that [tex]p = 0.45[/tex]

Sample of 35

This means that [tex]n = 35[/tex]

Mean and standard deviation:

[tex]\mu = 0.45[/tex]

[tex]s = \sqrt{\frac{0.45*0.55}{35}} = 0.0841[/tex]

What is the probability that fewer than 40% of the customers in the sample purchased the service contract?

This is the p-value of Z when X = 0.4. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.4 - 0.45}{0.0841}[/tex]

[tex]Z = -0.59[/tex]

[tex]Z = -0.59[/tex] has a p-value of 0.2776

0.2776 = 27.76% probability that fewer than 40% of the customers in the sample purchased the service contract.

Answer:

A. [tex]\frac{9}{5}[/tex]

Step-by-step explanation:

-[tex]\frac{1}{4}[/tex] ( -[tex]\frac{4}{5}[/tex] / [tex]\frac{2}{3}[/tex] ) 6

Note that when dividing fractions, you can flip one and multiply instead to gte the same answer.

-[tex]\frac{1}{4}[/tex]*6( -[tex]\frac{4}{5}[/tex] * [tex]\frac{3}{2}[/tex] )

[tex]\frac{-6}{4}[/tex] ( [tex]\frac{-4*3}{5*2}[/tex] )

[tex]\frac{-6}{4}[/tex] ( [tex]\frac{-12}{10}[/tex] )

[tex]\frac{-6*-12}{4*10}[/tex]

[tex]\frac{72}{40}[/tex]

Divide top and bottom by 8.

Answer:

2 2/7 + 4 1/2

Step-by-step explanation:

Exact form 95/14 for me

Mixed number will be 6 11/14

2 2/7 + 4 1/2 simplified fraction is 95/14.

To simplify the expression 2 2/7 + 4 1/2, we can convert the mixed numbers to improper fractions and then add them together.

Converting the mixed numbers to improper fractions:

2 2/7 can be written as (2 x 7 + 2)/7 = 16/7

4 1/2 can be written as (4 x 2 + 1)/2 = 9/2

Now we can add the fractions together:

16/7 + 9/2

To add fractions, we need to have a common denominator. In this case, the least common denominator (LCD) of 7 and 2 is 14.

Converting both fractions to have a denominator of 14:

16/7 x 2/2 = 32/14

9/2 x 7/7 = 63/14

Now we can add the fractions:

32/14 + 63/14 = (32 + 63)/14 = 95/14

Therefore, 2 2/7 + 4 1/2 simplified is 95/14.

Answer:

11+10i

Step-by-step explanation:

What you want to do is combine like terms, so take (2+4i)+(9+6i)

add the numbers with variables, in this case that is 4i and 6i, you get 10i.

Then you want to combine 2 and 9, you get 11.

You should end up with 11+10i, however in some cases you might write it as 10i+11 since some teachers want you to put the number with the highest variable first. If you need the answer for a recovery course (we know which one I just cant say it since this website doesn't like it lol) the answer will most likely be 11+10i
