Answer:
D. A value of 0.9 is more than 2 standard deviations from the mean
Step-by-step explanation:
A is wrong, because the standard deviation is +/-0.15 (the measure up or down from the mean)
B is wrong, because the mean is exactly 0.5
C is wrong, because 1 standard deviation up from the mean is 0.65, and 0.7 is outside of that.

Find the area enclosed by the x-axis and the curve x = 4 + et, y = t − t2.
Answers
Find where the curve intersects the x-axis; this happens when y = 0:
y = t - t ² = 0 → t (1 - t ) = 0 → t = 0, t = 1
Then the area of the bounded region is
[tex]\displaystyle\int_0^1 y(t) x'(t)\,\mathrm dt=\int_0^1 (t-t^2)e^t\,\mathrm dt=\boxed{3-e}[/tex]
(you can compute the integral by parts)

A larger number is double the sum of 3 and a smaller number. The larger number is 2 less than 3 times the smaller number. If y represents the larger number and x represents the smaller number, which equations model the situation? Check all that apply.
Answers
Answer:
y = 3x - 2
3x - y = 2
y = 2(x + 3)
Step-by-step explanation:
y = the larger number
x = the smaller number
A larger number is double the sum of 3 and a smaller number
y = 2(x + 3)
y = 6 + 2x
The larger number is 2 less than 3 times the smaller number.
y = 3x - 2
Make -2 the subject
y - 3x = -2
Make 2 the subject
y = 3x - 2
y - 3x = -2
(y - 3x) * -1 = -2 * -1
-y + 3x = 2
3x - y = 2
The answers:
y = 3x - 2
3x - y = 2
y = 2(x + 3)

A bakery buys a large bag of sugar that has 34 cups. They use 10 cups to make some cookies. They use the rest of the bag to make 144 giant muffins. Their customers want to know how much sugar is in each muffin.
Answers
Answer:
there would be 1 ÷ 6 sugar in each month
Step-by-step explanation:
The computation of the customers that want to know the sugar in each muffin is shown below
Here we assume the sugar in each muffin be x
Now there is 30 cups and 10 cups should be used for making some cookies
And, the rest would be use for making 144 gaint muffins
So, the equation that should be used is
10 + 144x = 34
144x = 24
x = 1 ÷ 6
So there would be 1 ÷ 6 sugar in each month

Jonah and Graham are working together. Jonah claims that (x+y)^2 = x^2+y^2. Graham is sure Jonah is wrong, but he cannot figure out how to show it. a.) Help Graham find as many ways as poissible to convince Jonah that he is incorrect. How can he rewrite (x+y)^2 correctly?
Answers
Answer:
Here is what I got hope it helps!!!!!!!
Step-by-step explanation:
Equivalent expressions are expressions with the same value.
The proper way to rewrite the equation is: [tex]\mathbf{(x + y)^2 = x^2 + 2xy + y^2 }[/tex]
Jonah's equation is given as:
[tex]\mathbf{(x + y)^2 = x^2 + y^2}[/tex]
To convince Jonah that Jonah's equation is wrong, Graham can do any of the following
Assume values for x and yExpand the equationAssume value for x and y
Let x = 2 and y = 4
[tex]\mathbf{(2 + 4)^2 = 2^2 + 4^2}[/tex]
[tex]\mathbf{36 = 20}[/tex]
The above equation is false.
So, it means that: [tex]\mathbf{(x + y)^2 \ne x^2 + y^2}[/tex]
Expand the equation
We have:
[tex]\mathbf{(x + y)^2 = x^2 + y^2}[/tex]
Open the bracket
[tex]\mathbf{x^2 + 2xy + y^2 = x^2 + y^2}[/tex]
Cancel out common terms
[tex]\mathbf{2xy = 0}[/tex]
The above equation is false.
So, it means that: [tex]\mathbf{(x + y)^2 \ne x^2 + y^2}[/tex]
The proper way to rewrite the equation is:
[tex]\mathbf{(x + y)^2 = x^2 + 2xy + y^2 }[/tex]

Lisa, Juan and isaac equally shared 1/2 of a cake which fraction of the whole cake did each of them recieve
Answers
Answer:
Each will receive [tex]\frac{1}{6}th[/tex] of the cake.
Step-by-step explanation:
Let the amount of cake = c
Lisa, Juan and Isaac are the persons who are sharing half of a cake equally.
Number of persons = 3
Part of the cake shared = [tex]\frac{c}{2}[/tex]
Fraction of the cake shared by each = [tex]\frac{\text{Amount of cake shared}}{\text{Number of persons who shared}}[/tex]
= [tex]\frac{\frac{1}{2}c}{3}[/tex]
= [tex]\frac{1}{6}c[/tex]
Therefore, fraction of total cake shared by each member will be [tex]\frac{1}{6}[/tex] of the total amount of cake.

Researchers in education are performing a study to see if listening to soothing music while taking a standardized math test increases the mean test score. The hypotheses are H 0 : mu=79 versus H a : mu>79 , and the p-value for the hypothesis test was 0.035.
At the 5 % significance level , what should the researchers conclude?
1. There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.
2. There is sufficient evidence to conclude that listening to soothing sounds decreases the mean test score.
3. There is insufficient evidence to conclude that listening to soothing sounds decreases the mean test score.
4. none of the above
Answers
Answer:
1. There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.
Step-by-step explanation:
A p - value less than 0.05 means that the test hypothesis is false or rejected.
In this question the test hypothesis is H 0 : mu=79 which is false as p-value is 0.035.
Whenever the p- value is less than the significance level H0 is rejected.
Hence the null hypothesis is rejected.
Therefore only choice 1 is correct.
There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.
There is sufficient evidence to support the claim.

Step-by-step explanation:
sixteen possible outcomes
A fair 4-sided die is rolled twice and we assume that all sixteen possible outcomes are equally likely.
The number of possible outcomes on rolling a four sided die twice is 16.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
A four-sided die in the shape of a pyramid is rolled twice.
The possible outcomes are
{ [tex](1,1),(1,2),(1,3),(1,4)[/tex]

Groups of 20 or more receive a 20% discount at the LA Zoo. Tickets range from $10 to $15, depending on age. What is the range in ticket price after the 20% discount?
Answers
Answer: $8 to $12
Step-by-step explanation:
The ticket prices range from $10 to $15 so the new range will see these two figures reduced by 20%.
$10 after the discount:
= 10 * (1 - 20%)
= $8
$15 after the discount:
= 15 * ( 1 - 20%)
= $12
Discounted ticket range is:
= $8 to $12
