<h3>Answer:</h3>

3) likely

4) 1/2; equally likely

<h3>Step-by-step explanation:</h3>

3) You are being asked to translate a numerical value to a subjective statement. There are no hard-and-fast rules for this. Generally, the meanings of the terms you're asked to choose from are ...

impossible: probability is zero. The outcome cannot occur.
unlikely: chances are less than even; often, "unlikely" means a probability of 10%, 5%, 1% or lower, depending on the context.
equally likely: probability is near 50%
likely: more likely than not. Again, this depends on the context.
certain: probability is 1. There is no chance the outcome will not occur.

An 80% probability is greater than 50%, so might reasonably be called "likely."

___

4) a. Four of the eight numbers are even, so the probability of obtaining an even number at random is 4/8 = 1/2.

b. A probability of 50% might reasonably be called "equally likely", as the probability the event will occur is equal to the probability it won't.

What is the value of y? A. y = -1 B. y = 0 C. y = 1 D. y = 3

luda_lava [24]

KT is twice the length of TM.

Multiply TM by 2:

TM = 2y +6

Now set KT and TM to equal and solve:

5y +3 = 2y +6

Subtract 3 from each side:

5y = 2y +3

Subtract 2y from each side:

3y = 3

Divide both sides by 3:

y = 3/3

y = 1

The answer is C.

When Elijah left his house in the morning, his cell phone battery was partially

lions [1.4K]

Answer:

The slope is -4.5

The slope means that Elijah's phone battery will decrease by 4.5 percent each hour.

Step-by-step explanation:

In the equation y = mx + b, m is the slope.

The coefficient in the equation B = 27 – 4.5t is -4.5. This means that -4.5 is the slope of the equation.

In the context of this problem, the slope will represent the percent that Elijah's phone battery will decrease per hour.

So, the slope means that Elijah's phone battery will decrease by 4.5 percent each hour.

6: REDUCE to simplest term. 4/1 + 15/2

vovangra [49]

Answer:

$\frac{4}{15}+\:\frac{1}{2}$ in the simplest term is:

$\frac{4}{15}+\frac{1}{2}=\frac{23}{30}$

Step-by-step explanation:

Given the expression

$\frac{4}{15}+\:\frac{1}{2}$

Thus, solving to reduce to the simplest term

$\frac{4}{15}+\frac{1}{2}$

LCM of 15, 2: 30

Adjusting fraction based on the LCM

so the expression becomes

$\frac{4}{15}+\:\frac{1}{2}=\frac{8}{30}+\frac{15}{30}$

Apply the fraction rule: $\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}$

$=\frac{8+15}{30}$

Add the numbers: 8+15 = 23

$=\frac{23}{30}$

Therefore, $\frac{4}{15}+\:\frac{1}{2}$ in the simplest term is:

$\frac{4}{15}+\frac{1}{2}=\frac{23}{30}$

A librarian has 4 identical copies of Hamlet, 3 identical copies of Macbeth, 2 identical copies of Romeo and Juliet, and one cop

lesantik [10]

Answer:

The number of distinct arrangements is 12600.

Step-by-step explanation:

This is a permutation type of question and therefore the number of distinguishable permutations is:

n!/(n₁! n₂! n₃! ... nₓ!)

where

n₁, n₂, n₃ ... is the number of arrangements for each object
n is the number of objects
nₓ is the number of arrangements for the last object

In this case

n₁ is the identical copies of Hamlet
n₂ is the identical copies of Macbeth
n₃ is the identical copies of Romeo and Juliet
nₓ = n₄ is the one copy of Midsummer's Night Dream

Therefore,

Number of distinct arrangements = 10!/(4! × 3! × 2! × 1!)

= 12600 ways

Thus, the number of distinct arrangements is 12600.
