What is the percent of decrease from 125 to 25

The temperature of a city changed by -24 degrees celsius over a 6-week period. The temperature changes by the same amount each w

Anton [14]

That amount, which I assume you're asking about, is a 4 degree drop in temperature each week.

<u>Complete Question</u>

The probability distribution table is given below:

$\left|\begin{array}{c|ccccccc}x&0&1&2&3&4&5&6\\P(x) &0.33 &0.24& 0.16& 0.12 &0.08 &0.05& 0.02\end{array}\right|$

Answer:

1.61

Step-by-step explanation:

The probability distribution table is given below:

$\left|\begin{array}{c|ccccccc}x&0&1&2&3&4&5&6\\P(x) &0.33 &0.24& 0.16& 0.12 &0.08 &0.05& 0.02\end{array}\right|$

We want to determine the mean number of times a person gave blood.

Expected Value, $E(x)=\sum x_i\cdot P(x_i)$

$=(0 \times 0.33)+ (1 \times 0.24)+(2\times0.16)+(3\times0.12)+(4\times0.08)+(5\times0.05)+(6\times0.02)\\=0+0.24+0.32+0.36+0.32+0.25+0.12\\=1.61\\$

The mean number of times a person gave blood based on this survey is 1.61.

Tony operates a skate rental company. He charges an equipment fee of $3 plus $6 per hour. Which equation represents this linear

slava [35]

Answer: A) y = 6x +3

Step-by-step explanation:

Let x represent the number of hours. $6 per hour can now be written as 6x.

Now, we must account for the $3 flat, fee and add it to 6x, getting 6x + 3

For the function y=-1+6cos(2pi/7(x-5)) what is the minimum value?

s344n2d4d5 [400]

Answer:

The minimum value of y is -7

Step-by-step explanation:

Given: $y=-1+6\cos(\dfrac{2\pi}{7}(x-5))$

We are given a cosine function.

We need to find minimum value of function.

$y=-1+6\cos(\dfrac{2\pi}{7}(x-5))$

Here y is depends on cosine function.

y is minimum when cosine is minimum because y is directly proportional to cosine function.

Minimum value of cos x is -1

Therefore, For minium value of y

$\cos(\dfrac{2\pi}{7}(x-5))=-1$

Minimum value of y

$y=-1+6(-1)$

$y=-7$

Hence, The minimum value of y is -7

What happens to the energy that is stored in cells? Check all that apply.

Stells [14]

A, D & E

Cells store energy in the form ATPs. These molecules power al the biochemical activities that would not occur spontaneously. Examples of these bioactivities are the contraction of actin filaments, glycolysis cycle, replication of DNA, cell division, gene expression, cell repair and etcetera.

Step-by-step explanation:

All ATPs are not spent at the same time, and futhermore, they are constantly replaced by the continuous process of cellular respiration that captures the chemical energy in the glucose molecules and stores them in ATP. During the release of this energy to power the biochemical reactions, much of it is lost as heat energy and this is why living organisms are always warm.
