1: Triple the quantity of a number “n” plus 4 equals 27. what would the expression look like?

[ Triple the quantity of a number “n” ] 3n

[ plus 4 ] + 4

[ equals 27 ] = 27

[ all together ] <u>3n + 4 = 27</u>

<u />

<u>Solving:</u>

[ given ] 3n + 4 = 27

[ subtract 4 from both sides ] 3n = 23

[ divide both sides by 3 ] n = 7 \frac{2}{3}

 

2:Seventeen equals seven less than three times a number “n” what would the expression look like?

[ Seventeen equals ] 17 =

[ seven less than ] - 7

[ three times a number “n” ] 3n

[ all together ] <u>17 = 3n - 7</u>

<u />

<u>Solving:</u>

[ given ] 17 = 3n - 7

[ add 7 to both sides ] 24 = 3n

[ divide both sides by 3 ] 8 = n

Have a nice day!

Butoxors [25]

Answer:

1. A is the null hypothesis. The null hypothesis is the statement in which everything is operating as expected; nothing unusual is going on.

2. C is the alternative hypothesis. The problem says that you are looking to see whether or not the machine is filling with an average of 24 ounces, so it could be over or under filling. B only accounts for under filling.

If P(a)=0.60 and P(b)=0.30, then a and b are independent events if
MariettaO [177]

Answer: \text{P(A or B)}=0.90

\text{P(A and B)}=0.18

Step-by-step explanation:

Given : P(A)=0.60 and P(B)=0.30

We will say A and B are independent events if :

\text{P(A or B)=P(A)+P(B)}\\\\=0.60+0.30=0.90

\text{P(A and B)=P(A) x P(B)}\\\\=0.60\times0.30=0.18

Thus , A and B are independent events if :

\text{P(A or B)}=0.90

\text{P(A and B)}=0.18

The surface area S of a single-celled organism may be found by multiplying 4π times the square of the radius r of the cell. Expr
Arte-miy333 [17]

Answer:

S(r)=4\pi r^2.

Step-by-step explanation:

It is given that, the surface area S of a single-celled organism may be found by multiplying 4π times the square of the radius r of the cell.  

We need to express S as a function of r.

Let r be the radius of the cell and S(r) be the surface area of single-celled organism when radius is r.

According to the question,

S(r)=4\pi \times r^2

S(r)=4\pi r^2

Therefore, the required function is S(r)=4\pi r^2.

Suppose the scores of students on a statistics course are normally distributed with a mean of 476 and a standard deviation of 85
soldi70 [24.7K]

Answer: 47.72 %

Step-by-step explanation:

Given : The scores of students on a statistics course are normally distributed with a mean of \mu=476 and a standard deviation of \sigma=85.

Let x be the random variable that represents the scores of students on a statistics course .

z-score : z=\dfrac{x-\mu}{\sigma}

For x= 476

z=\dfrac{476 -476 }{85}=0

For x= 646

z=\dfrac{646 -476 }{85}=2

Now, the probability of the students scored between 476 and 646 on the exam will be :-

P(476

Hence, the percentage of the students scored between 476 and 646 on the exam = 47.72 %
