Value of expression 1: 176
Value of expression 2: 32
Are they equivalent? No
How to evaluate expressions?Equivalent expressions are expressions that work the same way even though they look different. They have the same value for all values of the variables. They can be transformed into each other using the rules of algebra, such as the commutative, associative, and distributive properties.
Since the value of y is 2
Expression 1: 4y (y + 20)
To evaluate 4y (y + 20), substitute y = 2 into 4y (y + 20). That is:
4*2 (2 + 20) = 8(2+20) = 8(22) = 176
Expression 2: 4y + 24
To evaluate 4y + 24, substitute y = 2 into 4y + 24. That is:
(4*2) + 24 = 8 +24 = 32
Since the value of expression 1 is not equal to the value of expression 2. Thus, they are not equivalent.

A gardener wants to know if soaking seeds in water before planting them increases the proportion of seeds that germinate. To investigate, the gardener will assign 50 seeds to be soaked before planting and 50 seeds to be planted without being soaked. After two weeks, the gardener will record how many seeds in each group germinated and construct a 95 percent confidence interval for the difference in proportions. Which of the following conditions for inference should be met?
I. The seeds should be randomly assigned to a treatment.
II. The group sizes should be less than 10 percent of the population sizes.
III. The number of successful seeds and unsuccessful seeds in each group should be at least 10.
a. I only
b. II only
c. III only
d. I and III only
Answer:
d. I and III only
Step-by-step explanation:
I. The seeds should be randomly assigned to a treatment.
III. The number of successful seeds and unsuccessful seeds in each group should be at least 10.
The distribution of difference between two sample proportions :
Given :
Proportion 1 = P1 ;
Proportion 2 = P2 ;
Sample assignment for both samples 1 and 2 into the different treatment groups should be randomized, that is a simple random sampling of subjects into the treatment and control group. The sample design for difference between two sample proportions should be independent.
Finally each of the two proportions P1 and P2 should record a minimum of 10 successes and 10 non - successful Occurrences.

what is 691÷3 in long division
Answer:
230.33333.
Step-by-step explanation:
To know how much 691/3 is in long division, the following mathematical calculation must be performed, taking into account that long divisions seek to divide both the whole numbers and the decimals of the number:
691/3 = 230 (1 left over)
1/3 = 0.333333
230 + 0.33333 = 230.33333
Therefore, 691 divided by 3 results in 230.33333.

The model shows the addition expression 18 + 12
One expression that is equivalent to this sum is
3 + 6 + 4
3(6 + 4)
3 + 6(4)
3(6) + 4
Answer:
3(6 + 4)
Step-by-step explanation:
We have a model that is showing a certain expression, while knowing that the expression it's showing is "18 + 12"
To solve, all we have to do is simplify the answers. Do as following :
A. 3 + 6 + 4
This is already incorrect, the answer is split into three numbers and we are only looking for two, even if you try combining the numbers to make 2 terms, you will not get 18 + 12.
B. 3(6 + 4)
This is correct, the answer is a distribution problem that when solving :
(3(6) + 3(4))
18 + 12
Gives you what the question is asking for.
C. 3 + 6(4)
This is incorrect, when you distribute 6 and 4, you get 24. Leaving you with the expression 3 + 24.
D. This is incorrect, when you distribute 3 and 6, you get 18. Leaving you with the expression 18 + 4.

Step-by-step explanation:
Each year, ratings are compiled concerning the performance of new cars during the first 90 days of use. Suppose that the cars have been categorized according to whether a car needs warranty related repair (yes or no) and the country in which the company manufacturing a car is based ( in some country X or not in country X). Based on the data collected, the probability that the new car needs a warranty repair is .08, the probability that the car is manufactured by a company based in country X is .60, and the probability that the new car needs a warranty repair and was manufactured by a company based in country X is .025. Use this information to answer (a) Through (D)
a.)Suppose you know that a company based in country X manufactured a particular car. What is the probability that the car needs warranty repair?
b.)Suppose you know that a company based in country X did not manufacture a particular car. What is the probability that the car needs warranty repair?
c.)Are need for warranty repair and location of the company manufacturing the car independent?
Yes or NO or Not enough information
Answer:
1. 0.0417
2. 0.1375
3. no
Step-by-step explanation:
lets define:
A as the probability that a car needs a warranty repair.
B as probability taht the car is manufactured by a company that is based in country X
we have the
prob(A) = 0.08
prob(B) = 0.60
prob(A∩B) = 0.025
a. we are to calculate the probability taht a car manufactured in country X needs a warranty repair.
= p(AIB) =
[tex]P(\frac{AnB}{p(B)}) \\[/tex]
= 0.025/0.60
= 0.0417
2. Probability that car needs warranty repair given it was not manufactured in country X.
P(AIB')
= p(A∩B')/P(B')
= 0.08-0.025/1-0.60
= 0.055/0.40
= 0.1375
3. no, Need for warranty repair and location are not independent
The probability that the car needs warranty repair is 0.0417, the probability that the car needs warranty repair was not manufactured in company X is 0.1375 and no, there is no need for warranty repair and the location of the company manufacturing the car is not independent.
Given :
Ratings are compiled concerning the performance of new cars during the first 90 days of use.Based on the data collected, the probability that the new car needs a warranty repair is .08.The probability that the car is manufactured by a company based in country X is .60.The probability that the new car needs a warranty repair and was manufactured by a company based in country X is .025.a) The probability that the car needs warranty repair is given by:
[tex]\rm P(A|B) = \dfrac{ P(A\cap B)}{P(B)}[/tex]
[tex]\rm P(A|B) = \dfrac{0.025}{0.60}[/tex]
P(A|B) = 0.0417
b) The probability that the car needs warranty repair was not manufactured in company X is given by:
[tex]\rm P(A|B') = \dfrac{ P(A\cap B')}{P(B')}[/tex]
[tex]\rm P(A|B') = \dfrac{0.08-0.025}{1-0.60}[/tex]
P(A|B') = 0.1375
c) No, there is no need for warranty repair and the location of the company manufacturing the car is not independent.
