Answer: 27

Step-by-step explanation:

No. Of juniors: 8

Total students: 30

8/30 x 100 = 26.66

For this case we have that there are a total of 14 male students and a total of 16 female students. Thus, there is a total of 30 students distributed in the four categories.

On the other hand, we have a total of 8 Junior students.

Then, the probability of selecting a student Junior is \frac {8} {30} * 100 = 26.67

Rounding off we have 27%

Answer:

27%

Modeling Exponential Growth and Decay In Exercises 119 and 120, Find the exponential function
Lubov Fominskaja [6]

Answer:

There is no exponential function passing through (1,1) and (5,5).

Step-by-step explanation:

We have the following exponential function

y = Ce^{kt}

The function passes through these two points:

(1,1): This means that when t = 1, y = 1

(5,5): This means that when t = 5, y = 5.

So

(1,1)

y = Ce^{kt}

Ce^{k} = 1

e^{k} = \frac{1}{C}

(5,5)

y = Ce^{kt}

5Ce^{k} = 1

Ce^{k} = \frac{1}{5}

From above, we have that:

e^{k} = \frac{1}{C}

C\frac{1}{C} = \frac{1}{5}

1 = \frac{1}{5}

1 cannot be equal to 1/5, so this is wrong.

This means that there is no exponential function passing through (1,1) and (5,5).

Discount= 494.85/ 100

You save= $4.9485 ($494)

hannahs exercise goal is to walk at least 6 1/2 miles this week. she has already walked 2 3/4 miles this week. write and solve a
Ne4ueva [31]

We want to write an inequality that tells how much Hannah should walk this week. The inequality will be:

x ≥ (3 + 3/4) mi

<h3>Finding the inequality:</h3>

We know that she already did walk 2 3/4 miles this week, and she wants to walk at least 6 1/2 miles.

So to reach that minimum, she needs to walk:

(6  1/2)mi - (2 + 3/4) mi = (3 + 3/4) mi

And she can walk that or more, so the inequality is:

x ≥ (3 + 3/4) mi

Where x represents how much she will walk this week.
