f(x) = x² - 6x-7
g(x) = x + 1
Answers
Answer:
(-1, 0) and (8, 9)
Step-by-step explanation:
x² - 6x-7 = x + 1
x² - 7x - 8 = 0
(x - 8)(x + 1) = 0
x = -1, 8.
When x = - 1, y = 0
and x = 8, y = 9

On solving the provided questions, we can say that Probability, P( -1.6 \(\leq\) Z \(\leq\) 1.6 ) = 89.04%
What is probability?Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur. Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1. the percentage of occurrences in a complete set of equally likely possibilities that result in a certain occurrence compared to the total number of outcomes.

charging the phone for 1 minute ,it has 2%
i.e,1----->2
After 2 minutes from that time ,i.e total 3 minutes
it has 6% charge
i.e,3--------->6
from the both the above cases ,1 minute provide 2%=6/3

If 8x – 4 = 6x - 10, find the value of 5x.
Answers
Answer:
5x = - 15
Step-by-step explanation:
8x - 4 = 6x - 10 ( subtract 6x from both sides )
2x - 4 = - 10 ( add 4 to both sides )
2x = - 6 ( divide both sides by 2 )
x = - 3
Then
5x = 5 × - 3 = - 15

a. Pose several probability questions based on selecting a sample of 100 such computers.
b. What inferential statistics question might be answered by determining the number of such computers in a sample of size 100 that need warranty service?
Answers
a. The probability questions are given below.
b. The inferential statistics question is:
"What is the estimated proportion of computers in the population that need warranty service based on the observed proportion in the sample?"
We have,
a.
Probability questions based on selecting a sample of 100 computers:
- What is the probability that exactly 5 computers in the sample need warranty service?
- What is the probability that more than 10 computers in the sample need warranty service?
- What is the probability that at least 2 computers in the sample need warranty service?
- What is the probability that none of the computers in the sample need warranty service?
- What is the probability that the proportion of computers needing warranty service in the sample is greater than 0.3?
These questions can provide insights into the likelihood of certain outcomes within the sample of 100 computers.
b.
Inferential statistics question that can be answered by determining the number of computers needing warranty service in a sample of size 100:
"What is the estimated proportion of computers in the population that need warranty service based on the observed proportion in the sample?"
By determining the number of computers in the sample of 100 that need warranty service, we can use inferential statistics to make an estimate or inference about the proportion of the entire population of computers of that brand and model that may require warranty service.
This can help in understanding the warranty service needs of the entire population based on the information gathered from the sample.

The sum of four positive integers is 125. If you increase the first number by 4, decrease the second by 4, multiply the third by 4, and divide the fourth by 4, you produce four equal numbers. What is the smallest of the original numbers
Answers
Step-by-step explanation:
a + b + c + d = 125
a + 4 = b - 4 = 4c = d/4
a + 8 = b
a = b - 8
16c = d
b = 4c + 4
4a + 16 = d
b - 8 + 4c + 4 + c + 16c = 125
4c + 4 - 8 + 4c + 4 + c + 16c = 125
25c = 125
c = 5
d = 16c = 80
4a + 16 = d = 80
4a = 64
a = 16
b = a + 8 = 16 + 8 = 24
so, the numbers are
16, 24, 5, 80
solve for 8v = 3v + 25
Answers
Answer:
v = 5
Step-by-step explanation:
Collect like-terms:
\(8v = 3v + 25\)
\(8v - 3v = 25\)
\(5v = 25\)
Divide both sides by 5 to make v the subject:
\(v = 5\)
