Answer: 25

Step-by-step explanation:

Plug in x to the expression.

$5^5 * 5^{-3}\\$

When there is the same base of exponents is being multiplied the exponents add together and the base stays the same.

So this simplifies to, $5^2$ .

This then solves to 25.

To answer this question, you need to write a linear equation (because the graph is a visibly straight line) that models this situation, then plug in 12.

The general format for a linear equation is y=mx+b, where m is the slope and b is the y intercept. The y intercept of a line is where it crosses the y axis; for this line, it crosses the y axis at (0, 0) so the y intercept is 0.

To find the slope, use the slope equation: (y2-y1)/(x2-x1). For y1, y2, x1, and x2, just pick any two points on the line. We will use (1, 30) and (2, 60):

(60-30)/(2-1)

30/1

The line is y=30x.

Plug in 12 for x:

y=30(12)

y=360

3). 360

Hope this helps!!

A triangular sail has base of 4 feet and a height of 5 1/2 feet. What is the area of the sail?

Step2247 [10]

Area of a triangle: (1/2)bh, where b = base and h = height

(1/2) x 4 x (11/2)
= (4/2) x (11/2)
= 2 x (11/2)
= 11

three zebras are chilling in the desert. suddenly a lion attacks. each zebra is sitting on a corner of an equally length triangl

AnnyKZ [126]

Probability that no zebras collide is 0.25

The zebras are represented as z1, z2 and z3.

Z1 to B, Z2 to C, and Z3 to A come first $= (\frac{1}{2})^3$

Following that, z1 to C, z2 to A, and z3 to B = $(\frac{1}{2})^3$

Consequently, the likelihood of no collision is 2×1/8 = 0.25.

<h3>What are the types of probability distributions ?</h3>

Discrete and continuous probability distributions are the two main categories in which probability distributions fall. There are numerous varieties of probability distributions within each category.

The number of favorable outcomes of an event divided by the total number of possible outcomes of an event can be used to calculate the probability of an event.
The likelihood of a sure or certain event is one.
The likelihood of an impossibility is 0 (0).
Every event has a probability between 0 and 1.

I don’t know if you need to round, but you can do so on the answer for mondays if necessary

On Monday, the animals cost $1.03125.
On Tuesday, the animals cost exactly $1.
