Answer:
21 m^2
Step-by-step explanation:
(5*2) + (6*2) - (1*1) = 21
21m^2
Explanation:
First, we can find the areas of the two large rectangles.
A=lw
A=2*6
A=12m^2
A=lw
A=2*5
A=10m^2
Now, we can find the area of the small square where the two rectangles overlap. We can tell that the side lengths of the square are all equal to 1 (we know this because the side lengths of the rectangles are 1 less on one side).
A=lw
A=1*1
A=1m^2
Now, we can subtract 1m^2 from either of the two rectangles’ area we solved for earlier.
12m^2-1m^2
=11m^2
Then, we can add this area to the area of the other rectangle.
11m^2+10m^2
=21m^2

Noah spent some of his allowance on monday,1/8 of his allowance on Tuesday,1/8 of it on Wednesday and 2/8 of it on thursday.noah has none of his allowance money left.what fraction of his allowance did he spend on monday?explain
Answers
Answer:
Noah spent 4/8 of his allowance on Monday.
Step-by-step explanation:
Given that Noah spent some of his allowance on Monday, 1/8 of his allowance on Tuesday, 1/8 of it on Wednesday and 2/8 of it on Thursday, and has none of his allowance money left, to determine what fraction of his allowance did he spend on Monday the following calculation must be performed:
8/8 - (1/8 + 1/8 + 2/8) = X
8/8 - 4/8 = X
4/8 = X
Therefore, Noah spent 4/8 of his allowance on Monday.

Clarkson University surveyed alumni to learn more about what they think of Clarkson. One part of the survey asked respondents to indicate whether their overall experience at Clarkson fell short of expectations, met expectations, or surpassed expectations. The results showed that 5% of the respondents did not provide a response, 26% said that their experience fell short of expectations, and 65% of the respondents said that their experience met expectations. (a) If we chose an alumnus at random, what is the probability that the alumnus would say their experience surpassed expectations
Answers
Answer:
0.04
Step-by-step explanation:
We are given that
The probability that the alumnus did not provide response=5%
The probability that the alumnus did not provide response=[tex]\frac{5}{100}=0.05[/tex]
The probability that the alumnus would say their experience fell short of expectations=26%=0.26
The probability that the alumnus would say their experience met expectations=65%=0.65
We have to find the probability that the alumnus would say their experience surpassed expectations.
We know that
Sum of all probabilities =1
Using the property
The probability that the alumnus would say their experience surpassed expectations=1-(0.05+0.26+0.65)
The probability that the alumnus would say their experience surpassed expectation=0.04

(10-3)x(3-2^5) Use pemdas.
Answers
Answer:
-203
Step-by-step explanation:
(10−3)×(3−2^5 )
Subtract 3 from 10 to get 7.
7(3−2^5 )
Calculate 2 to the power of 5 and get 32.
7(3−32)
Subtract 32 from 3 to get −29.
7(−29)
Multiply 7 and −29 to get −203.
−203
So first we start with the parenthesis
(10-3) which is 7 and
(3-2^5) since exponents is next it would be (3-32) which is -29
So now we have 7 x -29 which is -203

A restaurant serves hot chocolate that has a mean temperature of 175 degrees with a standard deviation of 8.1 degrees. Find the probability that a randomly selected cup of hot chocolate would have a temperature of less than 161 degrees. Would this outcome warrant a replacement cup (meaning that it would be unusual)
Answers
Answer: The probability that a randomly selected cup of hot chocolate would have a temperature of less than 161 degrees =0.042
This outcome would warrant a replacement cup.
Step-by-step explanation:
Let x be a random variable that represents the temperature of hot chocolates.
GIven: Mean temperature = 175 degrees
standard deviation = 8.1 degrees
The probability that a randomly selected cup of hot chocolate would have a temperature of less than 161 degrees =[tex]P(x<161)[/tex]
[tex]=P(\dfrac{x-\mu}{\sigma}<\dfrac{161-175}{8.1})\\\\=P(Z<-1.7284) [Z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(Z<1.7284)\\\\=1-0.9580\\\\=0.042[/tex]
Hence, the probability that a randomly selected cup of hot chocolate would have a temperature of less than 161 degrees =0.042 < 0.5 (unusual)
i.e. this outcome would warrant a replacement cup.
Debra is buying prizes for a game at her school's fundraiser. The game has three levels of prizes, and she has already bought the second and third prizes. She wants the first prize to be nice enough to attract people to the game. The game's manufacturer has supplied her with the probabilities of winning first, second, and third prizes. Tickets cost $3 each, and she wants the school to profit an average of $1 per ticket. How much should she spend on each first prize
Answers
Answer:
$9.19
Step-by-step explanation:
We are given that
Cost of each ticket=$3
Average profit per ticket=$1
Expect gain for ticket purchaser must be -$1
Let x be the cost of first prize
Probability of first prize=0.15
Probability of second prize=0.30
Probability of third prize=0.45
Cost of second prize=$1.15
Cost of third prize=$0.74
Total probability=0.15+0.30+0.45=0.9
Probability of winning =0.9
Probability of losing=1-0.9=0.1
According to question
[tex]x(0.15)+0.30(1.15)+0.74(0.45)-3(0.1)=-1[/tex]
[tex]0.15x+0.378=-1[/tex]
[tex]0.15x=-1-0.378[/tex]
[tex]0.15x=-1.378[/tex]
[tex]x=-\frac{1.378}{0.15}=-9.19[/tex]
Hence, she spend money on each first prize=$9.19

Yes, Triangle ΔABC is an isosceles triangle.
What are the properties of Triangle?The properties of the triangle are:
The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.We can prove that triangle ABC is an isosceles triangle using the fact that BCD is a straight line, and the angles of a triangle add up to 180 degrees.
First, we note that the angles of triangle ABC add up to 180 degrees:
∠ABC + ∠ACB + ∠BAC = 180 degrees
Since ∠ACD and ∠ACB are adjacent angles, we know that:
∠ACD + ∠ACB = 180 degrees
Substituting the value of ∠ACD (117 degrees) into this equation gives:
117 degrees + ∠ACB = 180 degrees
Simplifying, we get:
∠ACB = 63 degrees
Now we can rewrite the equation for the sum of the angles of triangle ABC as:
∠ABC + 63 degrees + ∠BAC = 180 degrees
Substituting the value of ∠ABC (54 degrees) and simplifying, we get:
∠BAC = 63 degrees
Since ∠ABC = ∠BAC, we have shown that triangle ABC is an isosceles triangle.
Reasoning:
The angles of a triangle add up to 180 degrees.Adjacent angles on a straight line add up to 180 degrees.Substituting the value of ∠ACD into the equation for adjacent angles on a straight line gives ∠ACB = 63 degrees.Substituting the value of ∠ABC and simplifying the equation for the sum of the angles of triangle ABC gives ∠BAC = 63 degrees.Since ∠ABC = ∠BAC, triangle ABC is an isosceles triangle.Learn more about triangles here:

Null hypothesis is accepted
The average daily travel distance is less than 214 miles
Step-by-step explanation:
Step(i):-
Given that the size of the sample 'n' = 12
The mean of the Population = 214 miles
The mean of the sample = 198 miles
The standard deviation of the sample = 42 miles
Level of significance = 0.01
Step(ii):-
Null Hypothesis: H₀ : μ < 214 miles
Alternative Hypothesis :H₁: μ> 214 miles
Test statistic
[tex]t = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }[/tex]
[tex]t = \frac{198 -214}{\frac{42}{\sqrt{12} } }[/tex]
|t| = |- 1.319| = 1.319

13. (07.05 MC) What is the solution to the equation 5x + 2(x - 4) = 5x + x - 10? (1 point) O
Answers
Answer:
x = -2
Step-by-step explanation:
5x + 2(x - 4) = 5x + x - 10
First, we need to to multiply out the parathesis in the equation:
5x + 2(x - 4) = 5x + x - 10
5x + 2x - 8 = 5x + x - 10
Next, we can combine "like terms" to simplify the equation further:
5x + 2x - 8 = 5x + x - 10
7x - 8 = 6x - 10
Now we can isolate the variable "x" to one side:
7x - 8 = 6x - 10
x - 8 = -10
x = -2
To check our work, we can replace x with -2 in our original equation:
5x + 2(x - 4) = 5x + x - 10
5(-2) + 2 (-2 - 4) = 5(-2) + -2 - 10
-10 + 2 (-6) = -10 -2 - 10
-22 = -22

∴ [tex]\displaystyle \lim_{x \to 0^-} f(x) = -1[/tex]
We see from the function that when we approach 0 from the right, we will get a 1.
∴ [tex]\displaystyle \lim_{x \to 0^+} f(x) = 1[/tex]
Since the limit from the left does not equal the limit from the right, the limit as x approaches 0 of f(x) does not exist (DNE).
