The quadratic function f is represented by the equation f(x) = x2 - 2x + 2.
The table gives some of the values of the exponential function g(x).

Which of the following statements is FALSE?
A.
The functions f(x) and g(x) have the same value at x = 1.
B.
Both functions have a domain of all real numbers.
C.
The y-intercept of f(x) is greater than the y-intercept of g(x).
D.
f(3) > g(3)
Answer:
D is the answer
Step-by-step explanation:
For a: g(x) = 1 when x = 1, for f(x) 1^2 - 2(1) + 2 = 1, a is true.
For b: Both functions do have all real numbers for their domain, b is true
For c: the y-intercept of g(x) is x = 0, for f(x), it is 0^2 - 2(0) + 2 = 2, c is true
For d: g(3) = 7, f(3) = 3^2 - 2(3) + 2 = 5, d is false.

The average weight of a female hippopotamus is 1½ tons. How many pounds is this?
Answer:
3000 pounds
Step-by-step explanation:
Since there are 2000 pounds in a ton, find how many pounds there are by multiplying 1.5 by 2000
1.5(2000)
= 3000
So, this is 3000 pounds

Determine whether the first phrase is a subset of the second phrase, or the second phrase is a subset of the first phrase, or neither is a subset of the other. a. The set of people who were born in the U.S., the set of people who are U.S. citizens. b. The set of students studying a programming language, the set of students studying Java. c. The set of animals living in the ocean, the set of fish.
Answer:
Kindly check explanation
Step-by-step explanation:
A subset simply refers to a set whose elements are all members of a larger set.
Going by the definition :
The set of people born in the U.S is a subset of the set of people who are U. S citizens because citizenship in the U. S is not only attained by birth.
The set of Java students are all members of the set containing students studying a programming language, hence, The set of students studying Java is a subset of the set of students studying a programming language because Java is just one of the many different types of programming languages
{FISH_IN_OCEAN} is a subset of of the set of animals living in Ocean because not only fishes live in the ocean, fish is just one of the diverse marine animals that exist.

mum puts the chicken in the oven at 4:25 p.m. she let it bake covered for 10 minutes, then uncovered for 35 minutes more. what time will the chicken come out of the oven?
Answer:
5:10 pm
Step-by-step explanation:
The chicken will come out of the oven at 5:10 p.m. after baking covered for 10 minutes and uncovered for 35 minutes at 4:25 p.m.
Use the concept of addition defined as:
In maths, addition is the process of adding two or more numbers together. The numbers being added are known as addends, while the outcome of the addition process, or the final response, is known as the sum.
Given that,
Mom places the bird in the oven at 4:25 p.m.
Chicken bakes covered for 10 minutes.
Chicken bakes uncovered for 35 minutes.
The objective is to determine the time when the chicken will be taken out of the oven.
If your mom puts the chicken in the oven at 4:25 p.m. and bakes it covered for 10 minutes,
Then add 10 minutes to the initial time,
So, the chicken will be covered until 4:35 p.m.
Now, if she then bakes it uncovered for an additional 35 minutes,
Add another 35 minutes to the previous time,
This means the chicken will be cooked for a total of 45 minutes,
10 minutes covered + 35 minutes uncovered.
By adding 45 minutes to the starting time of 4:25 p.m., we find that the chicken will come out of the oven at 5:10 p.m.
Hence,
The time will be 5:10 p.m.

A random sample of 18 female neurologists and 21 male neurologists at public medical schools found that the average salary for female neurologists was $175,000 with a standard deviation of $15,000, while the average salary for male neurologists was $203,000 with a standard deviation of $22,000. Find a 99% confidence interval for the difference between the average salaries of male and female neurologists. (Round your answer to the nearest dollar.)
a) Write the formula that should be used to compute the interval.
b) Write the assumptions that need to be met in order to use the above formula.
c) Compute the interval.
Answer:
a) = x1`-x2`/ Sp √ ( 1/n₁ + 1/n₂)
b) it is assumed that the population standard deviations are known (which is sometimes met and sometimes not known).
c) The Confidence interval = [ 19131.77, 36868.23]
Step-by-step explanation:
Part a:
The 99% confidence interval for the difference between the average salaries of male and female neurologists is given by
(x1`-x2`) ±t∝/2(υ)* √ ( Sp²/n₁ + Sp²/n₂)
= x1`-x2`/ Sp √ ( 1/n₁ + 1/n₂)
where Sp ²= s₁² ( n1-1) + s₂²(n2-1) /(n1-1) + (n2-1)
Part B:
1) the sample should be normally distributed
2) it is assumed that the population standard deviations are known (which is sometimes met and sometimes not known).
Part C:
Calculations
1) H0: μ₁=μ₂ against the claim Ha: μ₁ ≠μ₂
2)The test statistic is
t= x1`-x2`/ √ ( Sp²/n₁ + Sp²/n₂)
where
Sp ²= s₁² ( n1-1) + s₂²(n2-1) /(n1-1) + (n2-1)
= 15,000²(17) + 22,000²(22) / 37
Sp ²= 103378640
3) D.f = n1+n2-2 =21+18-2 = 37
4) for 2 tailed test the critical value of t is obtained by
t≥ t∝/2 ( d.f)=t≥ t0.005 (37)= ±2.7154= ± 2.72
5) Putting the values
(x1`-x2`) ±t∝/2(υ)* √ ( sp²/n₁ + sp²/n₂)
28000 ± (2.72 * 3265.89)
=[ 19131.77, 36868.23].
The Confidence interval = [ 19131.77, 36868.23]

Answer:
A. The lowercase symbol, p, represents the probability of getting a test statistic at least as extreme as the one representing sample data and is needed to test the claim.
Step-by-step explanation:
The conditions required for testing of a claim about a population proportion using a formal method of hypothesis testing are:
1) The sample observations are a simple random sample.
2) The conditions for a binomial distribution are satisfied
3) The conditions np5 and nq5 are both satisfied. i.e n: p≥ 5and q≥ 5
These conditions are given in th options b,c and d.
Option A is not a condition for testing of a claim about a population proportion using a formal method of hypothesis testing.

Kiran is recalling Easter egg hunts from her childhood. She remembers that there were 2 Easter egg hunts where
she found 8 eggs each and 4 Easter egg hunts where she found 11leggs each. She also knows that she averaged
11.6 eggs per Easter egg hunt. This information is summarized in the table below.
Fill in the missing blank with the number of hunts where Kiran found 14 eggs.
Answer:
In 4 Easter egg hunts she found 14 eggs
Step-by-step explanation:
The table is missing, but the thing we need to complete in the table is a number X, where X is the number of easter egg hunts where she found 14 eggs.
We already know that:
2 times she found 8 eggs
4 times she found 11 eggs
X times she found 14 eggs.
And we also know that the average is 11.6 eggs.
Where the average can be computed as:
The quotient between all the eggs she found in all the Easter egg hunts, and the total number of Easter egg hunts were she attended.
She got a total of: 2*8 eggs + 4*11 eggs + X*14 eggs.
And she attended a total of 2 + 4 + X Easter egg hunts, then:
This is then:
[tex]avg = \frac{2*8 + 4*11 + X*14}{2 + 4 + X} = 11.6[/tex]
Now we just need to solve the above equation for X.
We can rewrite this as:
[tex]2*8 + 4*11 + X*14 = 11.6*(2 + 4 + X)[/tex]
[tex]16 + 44 + X*14 = 11.6*(6 + X)[/tex]
[tex]60 + X*14 = 11.6*(6 + X) = 11.6*X + 69.6[/tex]
[tex](14 - 11.6)*X = 69.6 - 60[/tex]
[tex]2.4*X = 9.6[/tex]
X = 9.6/2.4 = 4
This means that in 4 Easter egg hunts she found 14 eggs.
