Can someone help me with this in a scientific notation

Leviafan [203]

Answer:

3.762 x 10^-7

Step-by-step explanation:

Alright this has the same exact concept as other scientific notation problems.

First, multiply your first numbers: 4.18 x 9 = 37.62

Next, we add our powers together -4 +-4 = -8 (can also be read as -4 - 4 = -8)

We now have 37.62 x 10^-8

Wait! This isn't in scientific notation.

Taking a closer look at this we see 37.62 x 10^-8 can be adjusted by moving the decimal over to the left. Scientific notation must be in simplest form with only one number on the left of the decimal. This gives up 3.762.

Now we need to adjust our notation. Since we moved the decimal over one we are adding one more power to our problem.

Our current power of -8 is now adding a power due to moving the decimal place over one unit to the left. This is equivalent to saying -8 + 1 which equals -7. Now that we fixed our powers, we can put our equation back together for our final answer

3.762 x 10^-7

How would I solve this agai n

Svetllana [295]

Answer:

The area is 35 inches

Step-by-step explanation:

You will need to cut the shape into 3 parts

the 3 by 3

2 by 5

and 4 by 4

after that you multiply the numbers to get the area of the 3 parts.

The final step is to add them all up

The distance traveled (in feet) by the three-toed sloth can be modeled by f(s) =2.3s, where s is the time in minutes. Find the d

Mice21 [21]

$\huge{\boxed{\text{110.86 feet}}}$

We know that $f(s)=2.3s$ and $s=48.2$

Substitute in the value. $f(48.2)=2.3*48.2$

Use a calculator to multiply. $f(48.2)=\boxed{110.86}$

Using the normal distribution, the probabilities are given as follows:

a. 0.4602 = 46.02%.

b. 0.281 = 28.1%.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

The parameters are given as follows:

$\mu = 959, \sigma = 263, n = 37, s = \frac{263}{\sqrt{37}} = 43.24$

Item a:

The probability is <u>one subtracted by the p-value of Z when X = 984</u>, hence:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{984 - 959}{263}$

Z = 0.1

Z = 0.1 has a p-value of 0.5398.

1 - 0.5398 = 0.4602.

Item b:

$Z = \frac{X - \mu}{\sigma}$

By the Central Limit Theorem:

$Z = \frac{X - \mu}{s}$

$Z = \frac{984 - 959}{43.24}$

Z = 0.58

Z = 0.58 has a p-value of 0.7190.

1 - 0.719 = 0.281.

Who can help me with this

Lady bird [3.3K]

Answer:

Growth

Step-by-step explanation:

Given

$\frac{2}{3}(2.5)^x$

Required

Growth or decay

The general form is:

$y = ab^x$

Such that:

$b = rate$

For b, we have the following conditions:

$b > 1$ ----- Growth

$0$ --- Decay

$b = 1$ ---- None

Compare $\frac{2}{3}(2.5)^x$ to $y = ab^x$

$b = 2.5$

<em>Because 2.5 > 1, then the first condition applies (growth)</em>
