What is the surface area of a sphere that has a
diameter of 40 cm?
Answer:
A = 2512 cm²
Step-by-step explanation:
The surface area of a sphere is A = 2πr². With d = 40 cm, r = 20 cm, and so the surface area of this sphere is A = 2(3.14)(20 cm)², which works out to A = 2512 cm²
Answer:
Step-by-step explanation:
Find the area enclosed by the x-axis and the curve x = 4 + et, y = t − t2.
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]

How many different possible outcomes are there if you roll a four-sided die in the shape of a pyramid twice?
Answer:
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]

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.
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)
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?
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

Molly went out to dinner with her two friends. The total cost of the meal was $96.15. They used a coupon for 20% off. They paid 8.5% tax and left a 22% tip. If they split the cost equally, how much did each friend pay?
Answer: $48.24
Step-by-step explanation:
Since the total cost of the meal ate by Molly and her friends was $96.15 and they used a coupon for 20% off, paid 8.5% tax and left a 22% tip, the total amount paid will be:
= $96.15 + (20% × $96.15) + (8.5% × $96.15) + (22% × $96.15)
= $96.15 + $19.23 + $8.17275 + $21.153
= $144.70575
= $144.71
Since there are three friends, the amount that each person will pay will be:
= $144.71 / 3
= $48.24
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?
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]

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
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.
