I don’t get scientific notation. can someone help me on this?

Radda [10]

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. It may be referred to as scientific form or standard index form, or standard. Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

Name:

Effectus [21]

Answer:

8421

Step-by-step explanation:

8050 < abcd < 8500

We must have a = 8, so the number is 8bcd.

The value of a is 20 times the value of b, or a= 2b.

a = 8, so b = 4.

The value of b is 20 times the value of c, or b = 2c.

b = 4, so c = 2.

The value of c is 20 times the value of d, or c = 2d.

c = 2, so d = 1.

The secret number is 8421.

Suppose a normal distribution has a mean of 98 and a standard deviation of 6. What is P(x<110)? (The greater than sign is act

kvasek [131]

Using the normal distribution, the probability that x is less than 110 is:

A. 0.975.

<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.

The mean and the standard deviation are given as follows:

$\mu = 98, \sigma = 6$

The probability is the <u>p-value of Z when X = 110</u>, hence:

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

$Z = \frac{110 - 98}{6}$

Z = 2

Z = 2 has a p-value of 0.975.

Hence option A is correct.

If a rectangle measures 20 meters by 48 meters, what is the length, of the diagonal of the rectangle? Can you help me with this

Vikki [24]

$the \ width \ of \ the \ rectangle : \ w=20 \ m \\ \\ the \ length \ of \ the \ rectangle : \ l=48 \m \\ \\ Diagonal : \ \sqrt{w^2 + l^2}\\ \\D =\sqrt{20^2 + 48^2} \\ \\D=\sqrt{400+2304}=\sqrt{2704}= 52 \ m$
