Answers

Answer 1

Answer:

Answer:

-34

Step-by-step explanation:

first do substitution: -8 · 6 + -4 · -2 + 6

next do the multiplication: -48 + 8 + 6

add: -34

hope this helps!!!

Answer 2

Answer:

Answer:

-34

Steps:

-8x - 4y + x

-8x + x = -7x (combine like terms)

-7x - 4y

-7(6) - 4(-2) (plug in the numbers)

-42 +8=

-34

Sue subtracted 2.9 from 20.9 and got 1.8. Explain why this is not reasonable

Answers

because it is way to low even looking at it u can tell that it will still be in double diets

-- 20.9 is roughly 30.

-- 2.9 is roughly 3.

-- If Sue started with 30 and subtracted 3 from it, she would have 27.

-- 1.8 is nowhere near 27. It's not a reasonable answer.

(Actually, 20.9 - 2.9 = 18 . So you can see where maybe she got her
digits from, but she made some kind of bad mistake in handling them.)

A recent survey of 8,000 high school students found that the mean price of a prom dress was $195.00 with a standard deviation of $12.00. Alyssa thinks that her school is more fashion conscious and spent more than $195.00. She collected data from 20 people in her high school and found that the average price spent on a prom dress was $208.00. Which of the following is the correct z-statistic for this situation?

Answers

To calculate the z-statistic, we must first calculate the standard error.

Standard error is standard deviation divided by the square root of the population. In this case, it is equal to 2.68.

The z-score is defined the distance from the sample to the population mean in units of standard error.

z = (195 – 208)/2.68 = -4.86

the suntracker grows at a rate of 2.5 CM per day after the first 60 days.If this sunflower is 195 cm tall when it is 60 days old witer a expression to represent suntrackers height after 22 days or when it is 82 days old exspain how you found your answer, other sunflower is 235 cm

Answers

Given:
height at 60 days old - 195cm
height after 60 days old - 2.5cm per day

total height = 195 cm + 2.5cm(x - 60)
x = day measured

22 days old

total height = 195cm + 2.5cm(22-60)
t.h = 195cm + 2.5cm(-38)
t.h = 195cm - 95cm
t.h = 100 cm

82 days old

total height = 195cm + 2.5cm(x-60)
t.h = 195cm + 2.5cm(82-60)
t.h = 195cm + 2.5cm(22)
t.h = 195cm + 55cm
t.h = 250cm
