Write the following expression using the fewest possible terms.<br><br> (−2x − 13) + (19 + 5x)
MakcuM [25]

The rewritten form of the given expression using the fewest terms is; 3x + 6.

<h3>What is the rewritten form of.the expression using the least possible terms?</h3>

It follows from the task content that the given expression is to be rewritten using the fewest terms.

Since the given expression is;

( −2x − 13 ) + ( 19 + 5x )

By getting rid of the parentheses; we have;

-2x - 13 + 19 + 5x

By collecting like terms; we have;

-2x + 5x - 13 + 19

3x + 6

Therefore, the required rewritten form of the given expression is; 3x + 6.

The mean cost of a five pound bag of shrimp is 40 dollars with a standard deviation of 7 dollars. If a sample of 51 bags of shri
eimsori [14]

Answer:

P(|\bar{x}-40| > 0.6)=0.5404

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 40 dollars

Standard Deviation, σ = 7 dollars

Sample size,n = 51

We are given that the distribution of cost of shrimp is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

Standard error due to sampling =

=\dfrac{\sigma}{\sqrt{n}} = \dfrac{7}{\sqrt{51}} = 0.9801

P(sample mean would differ by true mean by more than 0.6)

P(|\bar{x}-40| > 0.6)\\\Rightarrow = 1-P(39.4

P(39.4 \leq x \leq 40.6) \\\\= P(\displaystyle\frac{39.4 - 40}{0.9801} \leq z \leq \displaystyle\frac{40.6-40}{0.9801})\\\\ = P(-0.6121 \leq z \leq 0.6121)\\= P(z \leq 0.6121) - P(z < -0.6121)\\= 0.7298 - 0.2702 =0.4596

P(|\bar{x}|-40 > 0.6)\\= 1-0.4596=0.5404

0.5404 is the required probability.

Alonzo loaned jeremy $325.18 for 1 year at a simple interest rate of 12 5/8%. how much interest will jeremy have to pay?
gayaneshka [121]

Jeremy will pay $41.05 interest.

We know that, Interest = PRT/100

where,

P = principal

R = rate

T = time

For given question, principal (P) = $325.18

interest rate R = 12 5/8%

                        = 12.625%

And period T = 1 year

We need to find the interest.

⇒ Interest = PRT/100

⇒ Interest = (325.18 × 12.625 × 1) / 100

⇒ Interest = 4105.3975 / 100

⇒ Interest = $41.05

Therefore, Jeremy will pay $41.05 interest.
