If f(x) = 3x+ 5 and g(x) = – 2x2 – 5x + 3, find (f + g)(x).
Answers
Answer: 1/8
Step-by-step explanation:(f÷g)(x) =
f(x) / g(x) =
2x / 22x
When we divide expressions with like bases, we subtract the exponents.
2(x - 2x) =
2-x
Now we substitute x = 3
So (f÷g)(3)
2-3
When we have a negative exponent, we perform the reciprocal of the expression and remove the negative sign from the exponent.

What is the domain? What is the range?
Answers
Given:
The graph of a function.
To find:
The domain and range of the graphed function in the interval notation.
Solution:
Domain: The set of x-values or input values is called domain.
Range: The set of y-values or output values is called range.
The given graph is divided into three pieces, first line, second parabola and third is again line. But the function is continuous.
The graph is defined for all values of x. So,
[tex]Domain=(-\infty,\infty)[/tex]
Therefore, the correct option is A.
The maximum value of the function is 4 and the graph approaches in the negative direction from both sides. So,
[tex]Range=(-\infty,4][/tex]
Therefore, the correct option is B.

Fail to reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually 0.32. C. Fail to reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually different from 0.32. D. Reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually 0.32.
Answers
Answer:
Type 1 error :
D. Reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually 0.32.
Type 11 error :
C. Fail to reject the claim that the proportion of people who write with their left hand is 0.32 when the proportion is actually different from 0.32.
Step-by-step explanation:
A type 1 error is committed when a true null rejected. That is an incorrect rejection of a true null. Hence, by rejecting the claim that proportion ofbpop
Type 2 error is made when a false null is adopted. Here, we fail to reject a false null. In the scenario above, type 11 error will be made if we fail to reject the claim that proportion of People who write with their left hand is 0.32, when the proportion is correctly not 0.32

Find the lowest common multiple of these five numbers.
Answers
We want to five the lowest common multiple of these 5 numbers. We will see that the lowest common multiple is:
[tex]98^{91}[/tex]
A multiple of a number N is any product between N and a positive integer. Here we want to get the smallest common multiple of the 5 numbers in the given set.
Here, the set is:
[tex]{98^{53}, 98^{64}, 98^{73}, 98^{88}, 98^{91}[/tex]
Remember the rule:
[tex]a^n*a^m = a^{n + m}[/tex]
Then we can see that:
[tex]98^{91} = 98^{91}*1 = 98^{88}*98^{3} = 98^{73}*98^{18} = 98^{64}*98^{27} = 98^{53}*98^{38}[/tex]
So:
[tex]98^{91}[/tex]
Is a common multiple of all the numbers in the set, and is the smallest common multiple because is equal to the largest number in the set.

our new training room can seat 150 employees if 6 tables consisting of 6 chairs are now taken what percentage of our new facility's seating is full at this point we have used what percentage of our new seating capacity
Answers
Answer:
24%
Step-by-step explanation:
Room capacity = 150
Each table consists of 6 chairs
The number of people seated = 6 tables occupied = 6 * 6 = 36 people
The percentage of seats filled :
(Number of people seated / total capacity) * 100%
(36 / 150) * 100%
0.24 * 100%
= 24%
Hence, 24% of training room is occupied

One year there was a total of 59 commercial and noncommercial orbital launches worldwide. In addition, the number of noncommercial orbital launches was two more
than twice the number of commercial orbital launches. Determine the number of commercial and noncommercial orbital launches.
Answers
Answer:
The number of commercial orbital launches is equal to 19 and the number of noncommercial orbital launches is equal to 40.
Step-by-step explanation:
IMPORTANT INFORMATION: The number of noncommercial orbital launches was two more than twice the number of commercial orbital launches.
Let's say that the number of commercial orbital launches is equal to x. Now, the number of noncommercial orbital launches is equal to 2x+2.
We are told that if we add the number of commercial and noncommercial orbital launches together we will get 59.
Therefore, if we add 2x+2 with x we should get 59:
2x+2+x=59
3x+2=59
3x=57
x=19
This is how we can come to the answer that the number of commercial orbital launches is equal to 19 and the number of noncommercial orbital launches is equal to 40 (2x+2=2*19+2=38+2=40).

At many college bookstores, students can decide whether to purchase or to rent a textbook for a class. A study was conducted to investigate whether the percent of rented textbooks for all science classes in the state was greater than the percent of rented textbooks for all literature classes in the state. The following hypothesis test was done at the significance level of α=0.05α=0.05.
H0:pS=pLHa:pS>pLH0:pS=pLHa:pS>pL
In the hypotheses, pSpS represents the proportion of all science textbooks that are rented, and pLpL represents the proportion of all literature textbooks that are rented.
All conditions for inference were met, and the resulting pp-value was 0.035. Which of the following is the correct decision for the test?
The pp-value is less than αα. Since 0.035<0.050.035<0.05, the null hypothesis is rejected, and the claim is supported. There is convincing statistical evidence that the proportion of all science textbooks that are rented is greater than the proportion of all literature textbooks that are rented.
A The pp-value is less than αα, and the null hypothesis is rejected. There is not convincing evidence to support the claim that the proportion of all science textbooks that are rented is greater than the proportion of all literature textbooks that are rented.
B The pp-value is less than αα, and the null hypothesis is not rejected. There is not convincing evidence to support the claim that the proportion of all science textbooks that are rented is greater than the proportion of all literature textbooks that are rented.
C The pp-value is greater than αα, and the null hypothesis is rejected. There is convincing evidence to support the claim that the proportion of all science textbooks that are rented is greater than the proportion of all literature textbooks that are rented.
D The pp-value is greater than αα, and the null hypothesis is not rejected. There is not convincing evidence to support the claim that the proportion of all science textbooks that are rented is greater than the proportion of all literature textbooks that are rented.
Answers
Answer:
A The p-value is less than α, and the null hypothesis is rejected. There is convincing evidence to support the claim that the proportion of all science textbooks that are rented is greater than the proportion of all literature textbooks that are rented.
Step-by-step explanation:
Given :
Percentage rented science textbooks = pS
Percentage rented Literature textbooks = pL
To test if percentage Science textbooks in the state was greater than percentage Literature textbooks :
H0: pS = pL
Ha: pS > pL
Pvalue = 0.035 ; α = 0.05
Decision Region :
If Pvalue < α ; We reject H0
In the scenario above,
Pvalue < α ; 0.035 < 0.05 ; Hence, we reject the Null ;
We conclude that There is convincing evidence to support the claim that the proportion of all science textbooks that are rented is greater than the proportion of all literature textbooks that are rented.
Chang knows one side of a triangle iS 13 cm. Which set of two sides is possible for the lengths of the other two sides
of this triangle?
• 5 cm and 8 cm
• 6 cm and 7 cm
• 7 cm and 2 cm
• 8 cm and 9 cm
Answers
Answer:
8 cm and 9 cm
Step-by-step explanation:
The rule for these types of problems is that the sum of the 2 shorter sides in a triangle is greater than the biggest side's length. If you think about it, it does seem sensible.
5+8 and 6+7 are both 13, but they aren't greater than the biggest side's length which is also 13.
7+2 is also wrong as it is 9, which is less than 13.
8+9= 17, and 17 is greater than 13.
So that's the answer.
