Vikki [24]

Answer:

y1= 0, y2= 5/3

Step-by-step explanation:

Remove the parentheses and multiply

then cancel the equal terms

collect the lie terms

move the variables to one side

divide both sides by two

split into possible cases

then solve the equation to get

y= 0 and

The area of a plot of land is 2496 square meters. A small part of the land is fenced. The ratio of the area of the plot of land

AfilCa [17]

My late response (haha): First, you would write a proportion.

Step 1: 2496 over 48 = x over 31
(x represents the area of the land that is not fenced).

Step 2: Cross multiply
2496 times 31 and x times 48

Step 3: Calculate
77376 = 48x

Step 4: Divide both sides by 48
77376/48 = 1612
48x/48 = x

Step 5: Write it as a sentence
The area of the land that is not fenced is 1612 squared meters.

Hope that helped! Good luck! :]

What is the range for f(x) = 2^x

Natali [406]

Given the function:

$f(x)=2^x$

The function can also be written as:

$y=2^x$

The range of the function will be all set of y values.

To find the range, let's graph the function below.

We have:

From the graph above, all possibe y values range from 0 to infinity.

Therefore, the range of the function is from zero infinity.

In interval notation:

Range = (0, +∞)

ANSWER:

4. (0, +∞)

A college financial adviser is interested in studying the number of students at his college who apply for loans when entering gr

Shalnov [3]

Answer:

0.7429

Step-by-step explanation:

Given that Of the 721 students at the college, 299 of them apply for loans when entering graduate school.

So p = proportion of students applying for loans = $\frac{299}{721} =0.415$

Each student is independent of the other and there are two outcomes

Hence out of 45 students the no of students who apply for loans say X is binomial with n =45 and p = 0.415

the probability that more than 16 of them apply for loans

= $P(X>16)\\= \Sigma_{x=17} ^{45} P(x)\\=\Sigma_{x=17} ^{45}(45Cx (0.415)^x (0.585)^{25-x} )$

=0.7429
