Match the following words to the correct definition:
_____ 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:

2/7 + square root of 121 (the third one)

Step-by-step explanation:

a rational number is a number where if you write it as a fraction, both the numerator and denominator are integers (numbers like 1 and 2 but not like 3.4 or 5.6)

the equation simplified a bit looks like this:

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

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.

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

Kelsea and Landon are playing in a park standing 100 feet away from each other. They both see a bird flying above them. The angles of elevation from each person to the bird are shown. How high is the bird from the ground? Round your answer to the nearest tenth.

Answers

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

26.6846 = adj

The bird is 26.7 ft. from the ground
