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

Answer:

x=0.3

Step-by-step explanation:

divide 8 by both sides to isolate x

8x/8= 2.4/8

2.4/8= 0.3, leaving x by itself, giving us x=0.3

Hope this helps and have a great week!

answer:x = 0.3

Step-by-step explanation:Simplifying

8x = 2.4

Solving

8x = 2.4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '8'.

(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

Pemdas (parenthesis, exponents, multiply, divide, add and subtract)
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

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

I hope this helps!

In 12 trial runs the average distance was 198 mi with a standard deviation of 42 mi At a = .01 test the claim that the average daily travel distance is less than 214 mi.


the claim is _____. H0: ___ H1: ____

Answers

Answer:

Null Hypothesis: H₀ : μ < 214 miles

Alternative Hypothesis :H₁: μ> 214 miles

The calculated value |t| = 1.319 < 3.4966 at 0.01 level of significance

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

Degrees of freedom   = n-1 = 12 -1 =11

critical value  [tex]t_{(0.005 , 11)} = 3.4966[/tex]

The calculated value |t| = 1.319 < 3.4966 at 0.01 level of significance

Null hypothesis is accepted

The average daily travel distance is less than 214 miles

BCD is a straight line.
ABC is a triangle.
Show that triangle ABC is an isosceles triangle.
Give a reason for each stage of your working.

Answers

It’s an isosceles triangle because angle A is equal to angle C (63deg). This is calculated by 180 - 117 = 63 degrees.
Using the exterior angle is equal to the interior angles property, angle A is equal to 117 - 54 (which is 63).
Because these two angles are equal to eachother, the triangle is isosceles.
Hope this helps and please mark me brainliest

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.

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

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.
