One eighth of a number is less than or equal to 3

Help me on this math shiiii

Ulleksa [173]

When you multiply two powers of the same base, you sum the exponents:

$a^b\cdot a^c = a^{b+c}$

So, in this case,

$4^4\cdot 4^{-9} = 4^{4-9} = 4^{-5}$

Now, negative exponents works like positive exponents, except you have to invert the number: i.e.

$a^{-b} = \dfrac{1}{a^b}$

So, you have

$4^{-5} = \dfrac{1}{4^5}$

Based on probability and if it is appropriate for a decision to be left up to chance, choose every situation that is both statis

svet-max [94.6K]

The situations that are both statistically fair and morally fair are Situation 2, Situation 3 and Situation 5

<h3>How to categorize the situations?</h3>

For a situation to be fair, the probability of every outcome must be equal.

We can now analyze each option using the above highlight

Situation 1

Alphabets = 26
Probability of vowel = 5/26
Probability of consonant = 21/26

The probabilities of vowels and consonant are not equal.

Hence, this situation is not fair

Situation 2

People = 4

P(Each) = 1/4

The probability of each participant is equal in the above scenario i.e. 1/4

Hence, this situation is fair

Situation 3

People = 5
P(Each) = 1/5

The probability of each cousin is equal in the above scenario i.e. 1/5

Hence, this situation is fair

Situation 4

Numbers = 5 i.e. 2 to 6
P(Prime) = 3/5
P(Composite) = 4/6

The probabilities of prime and composite numbers are not equal.

Hence, this situation is not fair

Situation 5

Roommates = 5
Cards = 5
Aces = 4
P(Each) = 1/5

All probabilities are equal in the above scenario i.e. 1/5

Hence, this situation is fair

Jane and Sammie are making decisions about their bank accounts. Jane wants to deposit

prisoha [69]

Answer:

Sammie

Step-by-step explanation:

Jane

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 550.00(1 + 0.05/4)(4)(10)

A = 550.00(1 + 0.0125)(40)

A = $903.99

Sammie

First, convert R as a percent to r as a decimal

r = R/100

r = 7/100

r = 0.07 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 550.00(1 + 0.07/12)(12)(10)

A = 550.00(1 + 0.005833333)(120)

A = $1,105.31

The six numbers in a set are 137, 128, 250, 136, 129, and 138. Which measures of the data increase when the outlier is included?

Leni [432]

Range increases. This is because range is the biggest number minus the smallest number. So when the biggest number is much bigger than the rest of the numbers, the range increases.
