if you were asked to express the weight in ounces of a ladybug in scientific notation, would the exponent of the 10 be positive

Nat2105 [25]

The <em><u>correct answer</u></em> is:

Negative.

Explanation:

Scientific notation is used to express very small or very large numbers.

Very small numbers are written in scientific notation using negative exponents.

Very large numbers are written in scientific notation using positive exponents.

Since a ladybug is very small, we would use the very small scientific notation, which uses negative exponents.

Assume that the heights of women are normally distributed with a mean of 63.6 inches and a standard deviation of 2.5 inches. If

vesna_86 [32]

Answer:

<h2>The probability is 58 %.</h2>

Step-by-step explanation:

This problem belong to a normal distribution probability.

Mean = 63.6

Standard Deviation = 2.5.

We have to find the probability of a height greater than 63.0.

Due to the normal probability, we need to find the Z score first:

$Z=\frac{x-u}{o}$ ; where x is the height, u is the mean, and o is the standard deviation.

$Z=\frac{63-63.6}{2.5} \\Z= -0.24$

Once we have our Z score, we find the probability with the z-table (attached). So, for a z score of -0.24 we have a probability of 0.42.

But, the problem is asking for height greater than 63.0, this mean that we have to subtract 0.42 from 1, giving as result 0.58, which means a 58% of probability,

The sum of two numbers is 67. the smaller number is 3 less than the larger number. what are the two numbers?

V125BC [204]

Let the larger number be x
The smaller number would be x-3

(x-3)+x=67
2x-3=67
2x=67-3
2x=64
x=64/2
x=32

Therefore the larger number is 32 and the smaller is (32)-3= 29

Hope I helped :)
