Hello there! :)
6^8*6^3
Here, we have the same base, so we add the powers:
6^11
Now, our expression looks like this:
6^11/6^5
Subtract the powers now that we divide:
6^6
So the missing exponent is 6. Hope it helps!
If you have any query, feel free to ask!

Answer:
The probability is 0.25
Step-by-step explanation:
Here is a probability question.
We want to know the probability of picking a card which is in the spades suit.
Now, what we know is that there are a total of 52 cards and we have 4 suites.
Each suite have equal number of cards. So definitely the number of cards in the spades suit will be 52/4 = 13 cards
Thus, the probability of picking any card in the spades suit = number of cards in the spades suit/ Total number of cards in the deck
Mathematically that would be 13/52 = 1/4 = 0.25
Y=3x is the answer to this equation
Complete Question
It has been found from experience that the mean breaking strength of a particular brand of thread is 9.72 oz with a standard deviation of 1.4 oz. Recently a sample of 36 pieces of thread showed a mean breaking strength of 8.93 oz. Can one conclude at a significance level of (a) 0.05, (b) 0.01 that the thread has become inferior?
Answer:
At both and the conclusion is that the thread has become inferior
Step-by-step explanation:
From the question we are told that
The population mean is
The standard deviation is
The sample size is n = 36
The sample mean is
The null hypothesis is
The alternative hypothesis is
Generally the test statistics is mathematically represented as
=>
=>
So
The p-value obtained from the z- table is
So at
So we reject the null hypothesis,hence we conclude that the thread has become inferior
So at
So we reject the null hypothesis,hence we conclude that the thread has become inferior
Answer:
1 or -1 if written
Step-by-step explanation:
Anything to the power of 0 is 1.
if the problem is written -(9x) though it would be negative one because the negative is outside of the parenthesis.
