State University has no honors English course but instead places all freshman scoring at least 60 on a proficiency exam (mean=50, standard deviation=10) into an advanced composition course. If the scores are normally distributed and there are 2,500 entering freshman, how many will be put into the advanced course?

Answers

Answer:

that put into the advanced course is 396.75

Step-by-step explanation:

The computation of that put into the advanced course is shown below:

P(X>60)

= P((X - mean) ÷ s > (60 - 50) ÷ 10)

= P (Z > 1)

= 0.1587

It could be checked by the standard normal table

Now that put into the advance course is

= 2,500 × 0.1587

= 396.75

Hence, that put into the advanced course is 396.75

A survey was distributed to 2.000 employees and 90 percent of these employees responded to the survey. Of the employees responding, 60 percent answered "yes" to a certain yes-no question and 72 employees did not answer that question. How many employees answered "no" to this question?

Answers

Answer:

720 employees

Step-by-step explanation:

Number of responded employees = 90% of 2000 employees = 1800 employees

Out of 1800 employees, if 60% answer yes, then the remaining 40% will answer "no". 72 employees did not respond to the survey.

Number of "no" answered employees = 40% of 1,800 employees = 720 employees( Answer)

_____ translation ______ rotation ______reflection _____dilation

A. Flip B. Enlarge/reduce C. Turn D. Slide

Answers

Answer:

A. Flip ---> reflection

B. Enlarge/reduce ---> dilation

C. Turn ----> rotation

D. Slide ----> translation

Step-by-step explanation:

D and translation

A and reflection

C and rotation

B and dilation

it just makes sense.

dilation means like if you stung by a bee and it starts to swell but it can also be used as a way to say something shrunk.

reflection means yourself flipped

rotation means like your turning around or turning something around

i don't know if translation has anything to do with slide but it was the last option and all the others make sense.

Answer:

Step-by-step explanation:

use an ASA triangle  with law of sine

since we know that 180 = 20 +45 + C   .. solve for C = 115°

now use  law of sines    c/ sin(C) = b/sin(B) .. and solve for b

Sin(20)*100/sin(115) = b

b = 37.73774 ft

that's the hypotenuse of the 45 triangle

SOH CAH TOA   to remember how trig functions fit

use b*Cos(45) = adj

The Empirical Rule says that: Group of answer choices outliers are within three standard deviations of the mean. about 32 percent of the data are beyond one standard deviation from the mean most business data sets are normally distributed in most business data we expect the mean and median to be similar.

Answers

Answer:

The Empirical Rule says that:

outliers are within three standard deviations of the mean.

Step-by-step explanation:

An outlier is an observed data value which lies some abnormal distance from other values in a population's random sample.  The cut-off for an outlier is three standard deviations from the mean in a normal distribution.  Therefore, the Empirical Rule concludes that 99.7% of data observed following a normal distribution lies within 3 standard deviations of the mean.  In summary, the empirical rule concludes that 68% of the data falls within one standard deviation, 95% percent falls within two standard deviations, while 99.7% falls within three standard deviations from the mean.

A homeowner uses GGG hours of natural gas heat and PPP hours of heat from a pellet stove to heat her house one month, with a total of 575757 therms of output. How many therms per hour does the pellet stove output

Answers

Answer:

0.0792therms/hour

Step-by-step explanation:

Given

Total output per month = 57 therm of output

Required

Total output of the pellet stove in one hour

Since 1month = 24×30 = 720hours

Hence:

57therms = 720hours

x therm = 1hour

Cross multiply

720×x = 57

x = 57/720

x = 0.0792 therms/hr

Hence the pellet stove use 0.0792therms/hour

Answer:

If the stadium has 100 stands, it can accommodate 20,000 spectators.

Step-by-step explanation:

In order to determine the number of spectators that can enter the cricket stadium, knowing that it has 100 stands and that each of these has a capacity of 200 seated spectators, the following calculation must be performed:

200 x 100 = X

20,000 = X

Which inequality describes all the solutions to -5x + 6 < 2(-3 − x)?

Answers

Answer: x>4

Step-by-step explanation:

The solution set for the given inequality is {-2, -3, -4, -5, -6,.......}.

The given inequality is 5x + 6 < 2(-3 - x).

What is a inequality?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given inequality can solved as follows:

5x + 6 < 2(-3 - x)

Multiply 2 to the bracket

5x + 6 < -6 - 2x

Add 2x to both the sides of inequality

5x + 6 + 2x < -6 - 2x + 2x

⇒7x+6<-6

Subtract 6 to both the sides of inequality

7x+6-6<-6-6

⇒7x<-12

Divide 7 to both the sides of inequality

7x/7<-12/7

⇒x<-12/7

⇒x<-1.7

Solution set = {-2, -3, -4, -5, -6,.......}

Therefore, the solution set for the given inequality is {-2, -3, -4, -5, -6,.......}.
