Answer:

It is better to buy the <u>10-ounce box for $1.95</u>

Step-by-step explanation:

1.) Set up a ratio to represent this problem.

Ounces : Price

10 : 1.95

14 : 2.81

2.) Find the unit price for the first ratio.

10 : 1.95

/10  /10

1 : 0.195

This means that a one-ounce box of cereal will cost $0.12

3.) Find the unit price for the second ratio.

14 : 2.81

/14  /14

1 : 0.20071428571

This means that a one-ounce box of cereal will cost $0.20

4.) Compare prices

$0.12 < $0.20

Therefore, it is better to buy the 10-ounce box for $1.95.

Hey there!

Answer = -21

Explanation:

Let's solve your equation step-by-step.

x + 7 = -14

Subtract seven from both sides:

x + 7 - 7 = -14 - 7

x = -21

So therefore, that is how you found your answer: x = -21

The number of days that homes stay on the market before they sell in Houston is bell-shaped with a mean equal to 56 days. Furthe
antoniya [11.8K]

Answer:

D. 8

Step-by-step explanation:

We have been given that the number of days that homes stay on the market before they sell in Houston is bell-shaped with a mean equal to 56 days. Further, 95 percent of all homes are on the market between 40 and 72 days.

As per empirical rule 95% of the data on bell curve lies between 2 standard deviations of mean.

So we can set an equation as:

72-56=2\sigma or

40-56=-2\sigma

16=2\sigma

\frac{16}{2}=\frac{2\sigma}{2}

8=\sigma

40-56=-2\sigma

-16=-2\sigma

\frac{-16}{-2}=\frac{-2\sigma}{-2}

8=\sigma

Therefore, the standard deviation for our given data is 8 and option D is the correct choice.

Can someone pls help me solved this problem! I need help help can someone help me I will mark you as brainiest! But plz help me!
Vilka [71]

Answer:

The number is <u>less than</u> 3.5

Step-by-step explanation:

Let us break up and convert each individual phrase into its equivalent in an equation.

"Three time" is 3*

"The difference of a number and three" is (3-x)

"Is greater than" is >

"The number decreased by five" is (x-5)

We can now put all of these parts together to get our equation

3*(3-x)>(x-5)

Now, we can simplify this and solve for x

3*(3-x)>(x-5)\\\\9-3x>x-5\\\\14>4x\\\\\frac{14}{4} >x\\\\\\frac{7}{2}>x\\\\x
