Prisha is buying sandwiches at a café for herself and her daughter. If she buys 2 tuna sandwiches, the cost will be $14. If she buys 1 tuna sandwich and 1 chicken sandwich, the cost will be $16. How much will the cost be if she buys 2 chicken sandwiches?
Answer:
18$
Step-by-step explanation:
2 tuna sandwiches= 14$
1 tuna sandwich= 14÷2 = 7$
1 tuna sandwich + 1 chicken sandwich = 16$
7$ +1 cs= 16$
1 chicken sandwich = 16$- 7$
1 chicken sandwich = 9$
2 chicken sandwiches = 9x2 = 18$

Given the following information: P(A) = 0.62 P(B) = 0.25 P(A and B) = 0.12 P(B given A) = 0.19 What is the probability of A or B? Round your answer to the nearest hundredth as needed. P(A or B) =|
Answer:
P(A or B) = 0.75
Step-by-step explanation:
Venn probabilities:
Supposing that we have two events A and B, the probability P(A or B) is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
In this question, we have that:
[tex]P(A) = 0.62, P(B) = 0.25, P(A \cap B) = 0.12[/tex]
So
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.62 + 0.25 - 0.12 = 0.62 + 0.13 = 0.75[/tex]
Then
P(A or B) = 0.75

What is the value of the expression 13/4 (8)? *
Answer: 26
(13/4) (8/1) =(13) (8)/ (4) (1) = 104/4 = 26
Step-by-step explanation:
1. A waste management service attempts to design routes so that each of their trucks pick-up on average four tons of garbage or less. A garbage collector believes, however, that he averages picking up more than four tons of garbage per day and decides to perform a hypothesis test. If the hypothesis test is performed at a 5% significance level and the resulting p-value is 0.04. Your conclusion should be:
2. It has been determined with 95% confidence that the proportion of on-line students at NYU who live in Brooklyn is between 0.73 and 0.77. Determine the sample proportion of on-line NYU students who live in Brooklyn.
3. Assume a normal distribution and use a hypothesis test to test the given claim.
According to city reports, it was found that the mean age of the prison population in the city was 26 years. Marc wants to test the claim that the mean age of the prison population in his city is less than 26 years. He obtains a random sample of 25 prisoners, and finds a mean age of 24.4 years and a standard deviation of 9.2 years. At a significance level of 0.05, what should his conclusion be?
Answer:
1.-Then we p-value indicates that we are in the rejection region we reject H₀
We support the claim of the garbage collector the average picking up more than 4 tn of garbage
2.- p = 75 %
3.-3.-t(s) is in the rejection region we accept H₀ we have not evidence to support Marc´s claim
Step-by-step explanation:
1.- If p-value is 0,04 and significance level α = 5 % or α = 0,05 then p-value < α
Test hypothesis should be ( x the average of garbage)
Null hypothesis H₀ x = 4 Tn
Alternative Hypothesis Hₐ x > 4 Tn
Then alternative hypothesis suggests a one tail-test to the right and
p-value < 0,05
Then we p-value indicates that we are in the rejection region we reject H₀
We support the claim of the garbage collector the average picking up more than 4 tn of garbage
2.- As we are dealing with a normal distribution the CI 95 % is symmetrical with respect to the mean, therefore the proportion of student living in Brooklyn is:
(0,73 + 0,77) /2
p = 0,75 p = 75 %
Test hypothesis:
Null Hypothesis H₀ μ = 26
Alternative Hypothesis Hₐ μ < 26
Alternative hypothesis tells us the test is a one-tail test to the left
Sample size n = 25
Sample mean μ = 24,4
Sample Standard deviation = 9,2
We assume normal distribution, and as n < 30 we use t-student table
with 24 degree of freedom
Significance level is 0,05 and df = 24 we find t (c) in t- student table
t(c) = 1,7109 test to the left t(c) = -1,7109
To calculate t(s)
t(s) = ( 24,4 - 26 ) / 9,2 / √25
t(s) = - 1,6 * 5 / 9,2
t(s) = - 0,87
Comparing t(s) and t(c) we have
t(s) > t(c)
t(s) is in the rejection region we accept H₀ we have not evidence to support Marc´s claim
f(x) = x2. What is g(x)?
A. g(x) = 4x²
B. g(x) = (1/4x)²
C. g(x) = (1/2x)²
D. g(x) = 1/4x²
Answer:
B. g(x) = (1/4x)²
Step-by-step explanation:
g(x) experiences a horizontal stretch where 0<|a|<1
This means we can eliminate A because that would be a horizontal compression since |a|>1
B seems to work because (1/4(4))^2=1
C does not work because you'll get 2 as your y-value
D does not work because you'd be taking 1/4 of x^2 which would give you 4.

Do the side lengths form a Pythagorean triple?
o yes
O no
Answer:
[tex] \sqrt{49 + 121} = \sqrt{170} [/tex]
No , The side lengths of the triangle does not form a Pythagorean triple
The value of x = 13.038 = √170
What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the triangle be ΔABC
Now , the base of the triangle BC = 11
The height of the triangle AB = 7
The hypotenuse of the triangle AC = x
Now , the length of AC can be calculated from the Pythagoras Theorem
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
And , AC² = AB² + BC²
Substituting the values in the equation , we get
AC² = 11² + 7²
AC² = 121 + 49
AC² = 170
Taking square roots on both sides of the equation , we get
The value of AC = √170
The value of AC = 13.038
Therefore , the value of x = 13.038
Hence ,
No , The side lengths of the triangle does not form a Pythagorean triple
The value of x = 13.038 = √170

A sample of size 20 from a normal distribution has sample mean 3.5 and sample variance 14.75. Find 90% confidence intervals for the variance and standard deviation of the distribution.
Answer:
Variance =9.2983, 27.6927
Standard deviation = 3.0493, 5.2624
Step-by-step explanation:
n = 20
S = 14.75
X² = chisquare
N-1 = degree of freedom
Alpha = 0.1
Alpha/2 = 0.1/2 = 0.05
1-0.1/2 = 0.95
Using statistics table
X² 19,0.05 = 30.14
X² 19, 0.95 = 10.12
A. 19(14.75)/30.14 , 19(14 75)/10.12
= 9.2983, 27.6927 for the variance of the population
B. Standard deviation = square root of variance
= √9.2983, √27.6927
= 3.0493, 5.2624

Vicky is studying French. She spends 1 hour reviewing each old chapter. She also spends 1.5 hours learning each
new chapter. She spends at least 10 hours per week studying French. Which graph could represent the possible
number of old chapters Vicky reviews, x, and new chapters Vicky learns, y, each week?
The answer is D
Step-by-step explanation:
The graph B is correct.
What is graph?The pictorial representation of data is called the graph.
Given that, Vicky gives 1 hour reviewing each old chapter and 1.5 hours learning each new chapter.
She spends at least 10 hours per week studying French.
We need to find the graph for this relation,
Let the number of old chapters Vicky reviews be x, and new chapters Vicky learns be y,
Therefore,
x + 1.5 y ≥ 10
Put the graph for the same.
Since the inequality sign is '≥' so the shaded part will be above the line and the inequality sign involves both equal and inequality so the line will be solid line without the dash.
We get the second graph is the correct graph.
Hence the graph B is correct.

10 POINTS FOR THE CORRECT ANSWER PLEASE HELP
Answer:
Step-by-step explanation:
The Pythagorean theorem says:
[tex]a^2+b^2=c^2[/tex]
where a and b are the two legs of the triangle and c is the hypotenuse. Here, let's say a = 6 and b = [tex]\sqrt{13}[/tex]. We then get the following equation:
[tex]c^2= (6)^2+(\sqrt{13})^2=49[/tex]
So c = 7. Technically, c can also equal -7 since (-7)^2 = 49 as well but that does not apply here because a side length cannot be <0. So 7 is the answer.
