Which equation has a solution of n = 4?

Allushta [10]

Answer:

D. 7n = 28

Step-by-step explanation:

Let's substitute 4 for n in each equation to check if it the resulting equation is correct:

$6+n=24\\ 6+4=24\\ 10\neq 24\rightarrow \text{Incorrect!}$

$5n=54\\5(4)=54\\20\neq54\rightarrow\text{Incorrect!}$

$12-n=16\\12-4=16\\8\neq16\rightarrow\text{Incorrect!}$

$7n=28\\7(4)=28\\28=28\rightarrow\text{Correct!}$

Therefore the answer is D

A coin will be tossed three times, and each toss will be recorded as heads (H) or tails (T). Give the sample space describing al

cricket20 [7]

Answer:

Sample space:

{HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

Third toss is heads:

{HHT, HTT, THT, TTT}

First toss is heads, second tails and third heads:

{HTH}

Explanation:

In order to find the sample space we need to write all the possible outcomes from tossing the coin three times.You can start by writting all the possible outcomes for the first toss being a head and finish with all the possible outcomes for the first toss being Tails. The number of elements in the sample space can be found by multiplying the possible outcomes of each toss together, so 2*2*2=8

{HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

For the third toss being heads we will have one restriction this time. Which is that the third toss is Tails. You can take the elements from the sample space where the third element is a tails. In this case, the number of elements can be calculated by multiplying the possible outcomes for only the first two tosses 2*2=4

{HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

For first toss is heads, second tails and third heads there is only one possible way for you to get this outcome so there is only one element to this set.

{HTH}

The table of values represents a continuous function. Which type of function describes g(x)?

Troyanec [42]

Answer:

Logarithmic

Step-by-step explanation:

For this exmaple, x is the one increasing by a third power for every y

Logarithmic is the opposite of exponential

Exponential is when y is the one increasing by a power for every x.

Therefore this one is logarithmic.

Loretta places 20 red tiles in a bag. How many blue tiles must be added to the bag to make the probability of randomly drawing a

Galina-37 [17]

Answer:

If the number of blue tiles in the bag is 180, then the probability of randomly drawing a red tile equal to 1/10.

Step-by-step explanation:

Total number of red tiles in a bag = 20

Let us assume the number of blue tiles in a bag = p

So, the total number of tiles in a bag = Red Tiles + Blue tiles

= 20 + p

Now, let us find the probability of drawing a red tile:

$\textrm{The probability of drawing a red tile} = \frac{\textrm{Total Number of red tiles}}{\textrm{Total Tiles}}\\= \frac{20}{20 + p}$

But, here the probability of drawing a red tile = 1/10

$\implies \frac{1}{10} = \frac{20}{20+p} \\\implies 20 + p = 200\\\implies p = 200- 20 = 180$

or, p = 180

Hence, if the number of blue tiles in the bag = 180, then the P Picking out a red tile ) is 1/10.
