In order to make 0.48 a fraction, I would suggest doing this:
0.48 -----> 48/100
Reduce 48/100 by four on both the numerator and the denominator:
12/25
And there is your answer.

A city has a population of 310,000 people.Suppose that each year the population grows by 6.5% . What will the po

brilliants [131]

Answer:

546,397 people

Step-by-step explanation:

We solve for the above question, using the formula for Exponential growth

The formula is given as

P(t) = Po (1 + r)^t

Po = Initial population = 310,000

r = Exponential growth rate = 6.5% = 0.065

t = Time in years = 9

P(t) = Population size after time t

Hence:

P(t) = 310,000 × (1 + 0.065)⁹

P(t) = 546,396.82088 people

Approximately =546,397 people

The population will be 546,397 people after 9 years.

Kruka [31]

Answer:

1. The slope of the least-squares regressin line is 11.364

2. The intercept of the least-squares regression line is 204.343

3. The residual corresponding to this observation is -10 calories

Step-by-step explanation:

1. In order to calculate the slope of the least-squares regressin line we would have to use the following formula:

slope of the least-squares regressin line=r*sy/sx

Therefore, slope=0.979*324.90/27.99

slope=11.364

2. In order to calculate the intercept of the least-squares regression line we would have to use the following formula:

intercept of the least-squares regression line=ybar - slope*xbar

intercept=662.88 - 11.364*40.35

intercept=204.343

3. In order to calculate the the residual corresponding to this observation we would have to use the following formula:

residual = observed y - predicted y

predicted y=11.364*x + 204.343

if the x value is 7, therefore predicted y=11.364*107 + 204.343

predicted y=1,420

Therefore, residual=1410 calories - 1420 calories

residual=-10 calories

In which direction does the graph of the function shown below open?

sp2606 [1]

Answer:

D. Up

Step-by-step explanation:

When a parabola has the form $y=ax^2+bx+c$ , It is vertical (opens up or down).

Because the variable "x" is squared.

If "a" is positive, then the parabola opens up, but if it is negative, then the parabola opens down.

In this case you have the quadratic function:

$f(x) = 2x^2+5x-4$

Which can be rewritten as:

$y = 2x^2+5x-4$

Therefore, it is vertical, because it has the form: $y=ax^2+bx+c$

You can observe that the value of "a" is:

$a=2$

Then, since "a" is positive, the parabola opens up.

You are purchasing soft drinks for the company annual party. You expect about 32 people to be there. You want to allow at least

qaws [65]

32*18=576 oz. 

Store A offers 24-12 oz cans for $5.89. That means $5.89 gets you 288 oz. Store B offers 12-12oz cans for $3.79, so that means $3.79 gets you 144oz. 

Store A is $5.89 per every 288 oz. You need 576 oz, which is double that. That means it will cost you twice as much as it would buying 24-12 oz cans: 
$5.89*2=$11.78 

Store B is $3.79 for 144 oz. As previously stated, you need 576 oz, so you'll need to buy 4 12-packs of 12 oz cans: 
$3.79*4=15.16 

So not only is Store A a better deal, but they'll save you $15.16-$11.78=$3.38 dollars.
