Answer:1.2
Step-by-step explanation:each term goes up by .05
There are more compact cars (4*10 = 40) compared to trucks (2*10 = 20); however, the pictogram might make it appear that there are more trucks because the individual truck icon is larger compared to an individual compact car icon.
To anyone giving this image a quick glance, they may erroneously conclude that there are more trucks since their eye would notice the trucks first. Also, the person might think there are more trucks because bigger sizes tend to correspond to more proportion.
In real life, a truck is larger than a compact car, but the icons need to be the same size to have the figure not be misleading.
A very similar issue happens with the mid-size cars vs the compact cars as well. The three mid-size car icons span the same total width as the compact cars do, indicating that a reader might mistakenly conclude that there are the same number of mid-size cars compared to compact ones (when that's not true either).

Step-by-step explanation:
Vicky jogged 4 1/2 miles or 9/2 miles or 4.5 miles
7/8 of 60 min=(7*60)/8=(7*15)/2= 52.50 min
4.5 miles....................52.50 min
? miles.......................60 min
vicky will have a rate of 5.14 miles/hour
Answer: a. 19.200 to 20.800
Step-by-step explanation:
Formula to find the confidence interval
:-

, where n is the sample size
= Population standard deviation.
= Sample mean
= Two tailed z-value for significance level of
.
Given : Confidence level = 95.44% = 0.9544
Significance level = 
Using standard normal z-value table ,
Two tailed z-value for Significance level of 0.0456 :

Also,
n=144

Then, the required 95.44% confidence interval for the population mean :-

Hence, the 95.44% confidence interval for the population mean is <u>19.200 to 20.800</u>.
Answer:
C
Step-by-step explanation:
Try each one using the formula for the volume of a cylinder, pi * r^2 * h:
A. 3.14 * 12^2 * 5 = about 2261 which does not equal 565
B. 3.14 * 10^2 * 4 = about 1256 which does not equal 565
C. 3.14 * 6^2 * 5 = about 565 which is correct!
D. 3.14 * 6^2 * 10 = about 1130 which does not equal 565
Therefore C is the right answer.
