Write the sentence as an equation. 323 decreased by d equals 369

$323 - d = 369$

Thus, d has to be negative, and you get:

$-d = 46$

Show a way to count from 170 to 410 using tens and hundreds. circle at least 1 benchmark number

Answers

Okay, so we start at 170

170

then we add 30 to reach the number 200

170+30=200

then we add 200 to reach the number 400

200+200=400

then we add 10 to reach 410

400+10=410

The benchmark numbers are bolded...

Suppose you buy a new car whose advertised mileage is 23 miles per gallon (mpg). After driving your car for several months, you find that its mileage is 19.4 mpg. You telephone the manufacturer and learn that the standard deviation of gas mileages for all cars of the model you bought is 1.07 mpg. A. Find the z-score for the gas mileage of your car, assuming the advertised claim is correct.
B. Does it appear that your car is getting unusually low gasmileage?

Answers

Answer:

Step-by-step explanation:

mu = population mean = advertised mean = 23

x = raw score = 19.4

sigma = population standard deviation = 1.07

z = (x - mu)/sigma

z = (19.4 - 23)/1.07

z = -3.36448598130841

z = -3.36

=======================================

The general rule is that if $-2 \le z \le 2$ , then the z score is not unusual. Otherwise, it is unusual.

Since z = -3.36 falls outside the range, the car is getting unusually low gas mileage.

Answers

5 to 12. All you do is switch the ratios around.

Answer:

The answer is 5 to 12. With this kind of problem all you need to do is make the numbers switch places. So it is 5 to 12, not 12 to 5. Hope this helped! :) (Btw, I am in Middle school lol. Why are u doing this in High School XD)
