Answer:
17.86
Step-by-step explanation:
You want to find y when x=8 using the equation y = 13.06 +0.6x.
EvaluationPut the value of the variable in place of the variable in the equation, and do the arithmetic.
y = 13.06 +0.6x
y = 13.06 +0.6·8 . . . for x=8
y = 13.06 +4.8
y = 17.86
The estimated value of y for x=8 is 17.86.

Answer:
A or C, but A is my guess.
Step-by-step explanation:
Answer:
A.) The sum will be an even integer.
Step-by-step explanation:
The conjecture that can be made about the sum of two even integers and one odd integer is that the sum will be an even integer. This is because even integers are numbers that are divisible by 2, and odd integers are numbers that are not divisible by 2.
For example, consider the sum of the even integer 6 and the odd integer 7. The sum of these two numbers is [tex]6 + 7 = 13[/tex], which is an odd integer. However, if we add another even integer to the sum, such as 4, the resulting sum is [tex]13 + 4 = 17[/tex], which is an even integer. This shows that the sum of two even integers and one odd integer is always an even integer.
This conjecture can be proven using mathematical induction. We can start by showing that the sum of any two even integers and one odd integer is always an even integer. Then, we can assume that the sum of any n even integers and one odd integer is also an even integer. Finally, we can show that the sum of n+1 even integers and one odd integer is also an even integer, using the assumption that the sum of n even integers and one odd integer is even. This will prove that the conjecture is always true.

The sample proportion is 0.5507, standard error is 0.0151, margin error is 0.030 and population proportion fall between 0.521<p<0.58
A.
One has 95% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion.
The sample proportion, pcap = 0.5507
b) sample size, n= 1084
The standard error of the mean, or simply standard error, indicates how different the population mean is likely to be from a sample mean.
standard error, SE = [tex]\sqrt{(pcap*(1-pcap)/n)}[/tex]
SE=[tex]\sqrt{(0.5507*(1-0.5507)/1084)}[/tex]= 0.0151

Margin of errors, in statistics, is the degree of error in results received from random sampling surveys.
Margin of error, ME = zc×SE
ME= 1.96×0.0151
ME= 0.030

Robbie pulls a marble out of the bag. What is the probability that the marble will be blue?
1/8
1/2
1/3
1/4
Answer: 1/4
Step-by-step explanation:
To find the probability that Robbie will pull a blue marble out of the bag, we need to first determine the total number of marbles in the bag. Since there are 2 blue marbles, 4 red marbles, and 2 yellow marbles, the total number of marbles in the bag is 2 + 4 + 2 = 8.
Next, we need to determine the number of blue marbles in the bag. Since there are 2 blue marbles, the number of blue marbles in the bag is 2.
Finally, we can use these numbers to calculate the probability that Robbie will pull a blue marble out of the bag. The probability is equal to the number of blue marbles divided by the total number of marbles, which is 2 / 8 = 1/4. Therefore, the probability that Robbie will pull a blue marble out of the bag is 1/4.
a production line manager wants to determine how well the production line is running. he randomly selected 90 items from the assembly line and found that 8 were defective. (assume all conditions have been satisfied for building a confidence interval). find the 99% confidence interval to estimate the population proportion of items that are defective.
The 99% confidence interval to estimate the population proportion of items that are defective is (0.0116, 0.1662).
Sample size , n = 90
defective items , x = 8
Sample proportion = x / n
= 8/90 = 0.0889
= 1- 0.0889 =0.9111
At 99% confidence level the z is ,
α = 1 - 0.99 = 0.01 , α/ 2 = 0.01 / 2
= 0.005
Zα/₂ = Z0.005 = 2.576 ( Using z table )
Margin of error Formula, E = Zα/2× (sqrt(((p-hat× (1 - p-hat)) /n)
= 2.575 ×sqrt((0.0889*0.9111) /90 )
E = 0.0773
A 99% confidence interval is
p-hat - E < p < p-hat + E
=> 0.0889 - 0.0773 < p < 0.0889 +0.0773
=> 0.0116 < p< 0.1662
Hence, confidence interval is (0.0116, 0.1662).

which of these graphs does not show a valid probability distribution? choose 1 answer: choose 1 answer:
The graph that does not show a valid probability distribution is option A.
Probability distribution refers to the mathematical function that provides the probabilities of occurrence of different possible outcomes for an experiment. It is a mathematical description of a random phenomenon in terms of its sample space and the probabilities of events. In order to determine if a probability distribution is valid, there are two criteria that must be checked. First determine whether each probability is greater than or equal to 0 and less than or equal to 1. Secondly, determine whether the sum of all of the probabilities equals 1. If both the conditions are true, then the probability distribution is valid, otherwise, the probability distribution is not valid. Based on the provided graphs, the first condition is met for all but the second condition is untrue for option A as the sum of probability is less than 1. Hence it is not a valid probability distribution.

Find the infinite sum of the geometric sequence with a = 4 , r = 4/6 if it exists.
Answer:
Step-by-step explanation:
The infinite sum of a geometric sequence is given by the formula:
S = a / (1 - r)
where a is the first term of the sequence and r is the common ratio. In this case, a = 4 and r = 4/6 = 2/3. Plugging these values into the formula above, we get:
S = 4 / (1 - 2/3) = 4 / (1/3) = 4 * 3 = 12
Therefore, the infinite sum of the geometric sequence with a = 4 and r = 2/3 is 12.

Can you explain me how factorize this : (x+1)²+3(x+1)+x+1
The factorization of the given expression is obtained as (x + 1)(x + 5).
How to factorise an algebraic expression?In order to factorize an expression first find all the terms that have the common factors. Then, write those terms in the form of product of factors. This is the way to factorize an expression.
The given algebraic expression is (x + 1)²+ 3(x + 1) + x + 1
It can be factorized as follows,
(x + 1)²+ 3(x + 1) + x + 1
⇒ (x + 1)²+ 3(x + 1) + (x + 1)
⇒ (x + 1)²+ 4(x + 1)
In all the three terms the common factor is (x + 1).
Take (x + 1) as common to get,
(x + 1)(x + 1 + 4)
⇒ (x + 1)(x + 5)
Hence, the given algebraic expression can be factorized as (x + 1)(x + 5).

What is decimal?In mathematics, decimals can be used as an alternative to fractions. You can express a fraction in decimal form, such as 0.5, rather than writing it out as 1/2, with zero in the place of the one and five in the place of the ten. Decimus, which means tenth in Latin, is the root of the word decimal. The decimal system is also known as a base-10 system because it uses 10 as its fundamental unit.
Decimal refers to any number in the decimal system. They are employed in the expression of both whole numbers and fractions. A "." (known as a decimal point) is inserted to demarcate the whole number from the fraction. The space between the digit in the ones place and the digit in the tenth place is known as the decimal point, and it serves as the separator between them.

(b) What should be added to the sum of 18x + 19y and 13xy + 12x to get 17xy-11y

4xy - 30y - 30x
Step-by-step explanation:
Lets say a=answer
Solve for a:
(18x + 19y) + (13xy + 12x) + a = 17xy-11y
18x + 19y + 13xy + 12x + a = 17xy-11y
18x + 12x + 19y + 13xy + a = 17xy-11y
30x + 19y + 13xy + a = 17xy-11y
30x + 19y-19y + 13xy + a = 17xy-11y - 19y ==> subtract 19y on both sides
30x + 13xy + a = 17xy-30y
30x + 13xy-13xy + a = 17xy-13xy-30y ==> subtract 13xy on both sides to
isolate a
30x + a = 4xy-30y
30x - 30x = 4xy - 30y - 30x ==> subtract 30x on both sides to isolate a
a = 4xy - 30y - 30x ==> simplify
