Answer: 0.6 cm

Step-by-step explanation:

Given : Over the past 4 years, Grandpa Ernie's height decreased by a total of 2.4 cm.

If  the height is decreased by the same amount each year.

Then, the change in Grandpa Ernie's height each year will be =

Total decrease in height ÷ 4

= 2.4 cm  ÷  4  = 0.6 cm

Hence, the  change in Grandpa Ernie's height each year = 0.6 cm

The nonprofit group Public Agenda conducted telephone interviews with three randomly selected groups of parents of high-school c
Vsevolod [243]

Answer:

Scatter plot is the answer for this type of graph of intelligence.

We can go up by 12 or 24 on the side graph

0,12,24,36,48,60,72,84,96,108 etc. So their will be 20 values if 12 and this best, labeled 12-228 this is because it stops at 202 and 228 may encourage other parents who read to take part in telephone interviews etc.

So that the first number 8 or 10 on y axis shows between 0 +12   (2/3 up to 12 low down) can be read as 2/3 of the first value so under 12 looks good. You will see that Step 1.

Step 2 Label x and y at end axis afterwards

Step 3. Write the name at side of y axis line

Call it   Attitudes to college education from the 605 parents interviewed.' = y line.  

Step 4. Write the name under x axis line

Call it  Percentage of parents who both disagree or agree  = x axis

Step 5 We can color code red blue and purple or pink dots to represent cultural race just three colors like orange blue and silver.

Step 6  Group each grid in the chart into percentages

by using  imputing the value before /202  the first group ie) 10 (B) strongly disagree you enter into calculator  10/202 = 4.95% percentage and do this a few times for each

11/202   shows somewhat disagree percentage for black parents (B) can be put next to each result. (B) SOMD = 5.44%

Then when you do Hispanic start with 8/202  as this is under 10 we move the decimal back still 2 units if it was a larger number it would still be placed back 2 units to the left  (H) STrD = 3.96%

Step-by-step explanation:

So for step 6 you just need the data ive done 4 for you just 8 more needed for percentages.

Step 7.  You design a way to show all the percentages so you condense the data to evenly show a broad graph

We know that 154/202 = 76.23% is the highest percent so if you are showing 8 or more values we can show 10 values 10%, 20%, 30% at the bottom of the x axis.

Just remember to do your percentages 8/201 for white parents as the number 202 was for the other groups.

Step 8. Do a color code last to the right. Just away from any dots with Black parents ------- put the color in the bar

one on top of each other in a box to the right of the graph after the letter x but higher up.

Step 9 You could draw a line of fit and call it a scatter graph

And underneath the actual graph write 2 lines about what a line of fit is.

This shows a modest and intelligent way of keeping groups in proportion to their warranted and valued answer.

This must be a subtle way for parents to absorb all advanced data shown.

Its just a challenge to see if all the percentages can fit and meet up in a coordinated way. If it doesn't work then perhaps you can relabel x axis frequency and show the same data on y on x but a new name so it can always be understood and both meet at same numbers.  But i think the percentages would work and show better intelligence, along with a color code showing pretty stars or dots to make the colors coordinated is another way to make all parents feel valued whatever the race.

Variable: Temperature
saul85 [17]
  • The 20th percentile represent the temperature value which is less than or equal to the 20% of the temperature values in the distribution.
  • The 20th percentile temperature is 36.5°C which is Mr. Whitney's temperature.
  • The mean temperature value in °Fahrenheit is 98.249°F
  • The standard deviation value of temperature in °F is 32.734°F

The 20th percentile represents the score at which less than or equal to 20% of the scores in a distribution may be found. This is the score at which less than or equal to 20% of the temperature values in the distribution may be found.

Mr. Whitney's temperature :

20th percentile ;

20% of (n)

Where n = count of temperature values = 130

20% × 130 = 26th term

The 26th falls in 36.5 temperature value.

The mean temperature reading in degree Fahrenheit :

°F = (9/5)°C + 32

Mean in °C = 36.805

°F = (9/5) × 36.805 + 32

°F = 66.249 + 32

= 98.249°F

The standard deviation of temperature reading in degree Fahrenheit :

°F = (9/5)°C + 32

Standard deviation in °C = 0.408

°F = (9/5) × 0.408 + 32

°F = 0.7344 + 32

= 32.7344°F

VikaD [51]

Answer:

Their headquarters contains <u>420000</u> employees.

Step-by-step explanation:

The company has two office buildings which hold 30,000 employees.

The headquarters contains 14 times as many employees as the overseas branch.

Therefore, the number of employees in the headquarters is:

14 * 30000 = 420000 employees

Their headquarters contains 420000 employees.

Select the correct interpretation of the probability of getting an 11 when a pair of dice is rolled. Interpret an event as signi
klio [65]

Answer:

c. Not significant at .055

Step-by-step explanation:

When a pair of dice is rolled, we have 6²=36 possible outcomes. Only 2 of these outcomes have a total score of 11:

  1. When the first dice is 5 and the second is 6.
  2. When the first dice is 6 and the second is 5.

Then, we can calculate the probability of getting 11 as the quotient between the successs outcomes and the total outcomes.

Then, the probability of getting 11 is:

P=\dfrac{X}{N}=\dfrac{2}{36}=0.055

This probability is not equal or less than 0.05, so it is not significant at 0.055.

Jinghua hiked 4 1/2 miles through the woods in 2 1/4 hours. She hiked the return trip at the same average rate but by a differen
Anna007 [38]

Answer:

5 miles.

Step-by-step explanation:

Consider the question: Jinghua hiked 4 1/2 miles through the woods in 2 1/4 hours. She hiked the return trip at the same average rate but by a different route taking 2 1/2 hours. How many miles did Jinghua hike on the return trip ?

First of all, we will find Jinghua's speed using given information as:

\text{Speed}=\frac{\text{Distance}}{\text{Time}}

Convert mixed fractions into improper fractions:

4\frac{1}{2}\Rightarrow \frac{9}{2}

2\frac{1}{4}\Rightarrow \frac{9}{4}

\text{Jinghua's speed}=\frac{\frac{9}{2}\text{ Miles}}{\frac{9}{4}\text{ Hours}}

Using property \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{ad}{bc}:

\text{Jinghua's speed}=\frac{9*4\text{ Miles}}{9*2\text{ Hours}}

\text{Jinghua's speed}=\frac{2\text{ Miles}}{\text{ Hour}}

We know that distance is equal to the product of speed and time.

\text{Distance}=\text{Speed}\times\text{Time}

Since we have been given that Jingua hiked the return trip at the same average rate, so distance covered by her on return trip would be speed (2 miles her hour) times given time (2 1/2 hours).

\text{Distance covered by Jingua on return trip}=\frac{2\text{ Miles}}{\text{ Hour}}\times 2\frac{1}{2}\text{ Hours}

\text{Distance covered by Jingua on return trip}=2\text{ Miles}\times \frac{5}{2}

\text{Distance covered by Jingua on return trip}=5\text{ Miles}

Therefore, Jingua hiked 5 miles on her return trip.
