Answer:
21 feet
Explanation:
Using pythagorean theorem to find the length of the added length of the bottom.
A^2+B^2=C^2 or 4^2+B^2=5^2 or 16+B^2=25
25-16=9 so B^2 is 9 and the square root of that is 3 so B is 3. Then you add 15+3+3 to get 21.

Decrease £19064.67 by 9.5%
Give your answer rounded to 2 DP.
Answer:
New amount (decrease) = £17253.53
Step-by-step explanation:
Given the following data;
Amount = £19064.67
Percentage = 9.5%
To find the percentage decrease;
[tex] Percentage \; cost = \frac {9.5}{100} * 19064.67 [/tex]
[tex] Percentage \; cost = 0.095 * 19064.67 [/tex]
Percentage cost = £1811.14
New amount (decrease) = Original amount - percentage cost
Substituting into the equation, we have;
New amount (decrease) = £19064.67 - £1811.14
New amount (decrease) = £17253.53

A growth-mindset researcher plans to take an SRS of 200 teenagers from the population of teenagers in North America to see what proportion of teenagers sampled are pursuing a goal they have set for themselves. Suppose that 75% of teenagers in North America are pursuing a goal they have set for themselves. Let p represent the proportion of a sample of 200 teenagers in North America who are pursuing a goal they have set for themselves. What are the mean and standard deviation of the sampling distribution of p?
Answer:
The mean of the sampling distribution of p is 0.75 and the standard deviation is 0.0306.
Step-by-step explanation:
Central Limit Theorem:
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
75% of teenagers in North America are pursuing a goal they have set for themselves.
This means that [tex]p = 0.75[/tex]
Sample of 200.
This means that [tex]n = 200[/tex].
What are the mean and standard deviation of the sampling distribution of p?
By the Central Limit Theorem
Mean [tex]\mu = p = 0.75[/tex]
Standard deviation [tex]s = \sqrt{\frac{0.75*0.25}{200}} = 0.0306[/tex]
The mean of the sampling distribution of p is 0.75 and the standard deviation is 0.0306.

Tamanika received a raise in her hourly pay, from $14.00 to $18.34. Find the percent change.
13) Find the values of x and y.
Answer:
x = 64°
y = 71°
Step-by-step explanation:
✔️x = 180 - 2(58) (isosceles triangle)
x = 180 - 116
x = 64°
✔️y + 45° + x = 180° (angles on a straight line)
y + 45° + 64° = 180° (substitution)
y + 109 = 180°
y = 180° - 109°
y = 71°
There are 10 years in 1 decade. Deron is 2 decades, 4 years, and 8 months old. His brother John is half as old. How old is John?
Answer:
John is 1 decade, 2 years, and 4 months old
Step-by-step explanation:
Since we knot that John is half as old we just have to divide Derons age by two, and we will do that by dividing the number of decades, a number of years, and a number of months by two, and so we get that John is...
(2/2) decades, (4/2) years, and (8/2) months old =
= 1 decades, 2 years, and 4 months old
John is 1 decades, 2 years, and 4 months years old.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
We have to given that;
There are 10 years in 1 decade.
And, Deron is 2 decades, 4 years, and 8 months old.
Since, His brother John is half as old.
Hence, Age of John is,
⇒ (2 decades, 4 years, and 8 months) / 2
⇒ 1 decades, 2 years, and 4 months
Thus, John is 1 decades, 2 years, and 4 months years old.

Find the y-intercept of a line parallel to 8x – 2y = 12 and passes through the point (5, 3).
Answer:
-17
Step-by-step explanation:
8x -2y= 12
Divide the whole equation by 2:
4x -y= 6
Rewrite the equation into the slope-intercept form (y=mx+c, where m is the gradient while c is the y-intercept).
-y= -4x +6
y= 4x -6
Thus, gradient of given line= 4.
Since parallel lines have the same gradient, gradient of line= 4.
y= 4x +c
To find the y-intercept of the lone, substitute a pair of coordinates.
When x=5, y=3,
3= 4(5) +c
3= 20 +c
c= 3 -20
c= -17
Thus, the y-intercept of the line is -17.

Travis's income is $7200a month, and he plans to budget 1/2 of his income for rent and 1/6 of his income for electricity.What fraction of his income does he plan to spend each month on these two items together? Express your answer in lowest terms.
Answer:
Travis plans on spending 2/3 of his income which is $4800
Step-by-step explanation:
1/2 = 3/6 and 3/6 + 1/6 = 4/6 and 4/6 = 2/3
Answer:
2/3
Step-by-step explanation:
7200 / 2 = 3600 rent
7200/ 1/6 = 1200 electricity
3600 +1200 = 4800
4800/7200 = the same as simplified 48/72
We know our 12x table = 4/6
We can simplify 4/6 as 2/3
Pier 1 Imports is running a 10% sale on furniture. If Amanda spent $378.99 on furniture before tax, what was the price of the furniture before the discount and tax?
Answer:
$421.10
Step-by-step explanation:
If the discount is 10%, that means the sale price is 90% of the original price.
Write the equation that represents that:
378.99 = 0.9x. Solve for x. Divide both sides by 0.9
378.99/0.9 = 421.10
That is the price before the discount and tax.

Weary of the low turnout in student elections, a college administration decides to choose an SRS of three students to form an advisory board that represents student opinion. Suppose that 48% of all students oppose the use of student fees to fund student interest groups, and that the opinions of the three students on the board are independent. Then the probability is 0.48 that each opposes the funding of interest groups.Call the three students A, B, and C. Give the probability of each possible outcomes (AcBcCc are the events that the students support the student fee usage).Pr(ABC) = _____Pr(ABCc) = _____Pr(ABcC) = _____Pr(AcBC) = _____Pr(ABcCc) = _____Pr(AcBCc) = _____Pr(AcBcC) = _____Pr(AcBcCc) = _____
Answer:
[tex]P(ABC) = 0.110592[/tex]
[tex]P(ABC^c) = 0.119808[/tex]
[tex]P(AB^cC) = 0.119808[/tex]
[tex]P(A^cBC) = 0.119808[/tex]
[tex]P(AB^cC^c) = 0.129792[/tex]
[tex]P(A^cBC^c) = 0.129792[/tex]
[tex]P(A^cB^cC) = 0.129792[/tex]
[tex]P(A^cB^cC^c) = 0.140608[/tex]
Step-by-step explanation:
Given
[tex]P(A) = P(B) = P(C) = 48\%[/tex]
Convert the probability to decimal
[tex]P(A) = P(B) = P(C) = 0.48[/tex]
Solving (a): P(ABC)
This is calculated as:
[tex]P(ABC) = P(A) * P(B) * P(C)[/tex]
This gives:
[tex]P(ABC) = 0.48*0.48*0.48[/tex]
[tex]P(ABC) = 0.110592[/tex]
Solving (b): [tex]P(ABC^c)[/tex]
This is calculated as:
[tex]P(ABC^c) = P(A) * P(B) * P(C^c)[/tex]
In probability:
[tex]P(C^c) = 1 - P(C)[/tex]
So, we have:
[tex]P(ABC^c) = P(A) * P(B) * (1 - P(C))[/tex]
[tex]P(ABC^c) = 0.48 * 0.48 * (1 - 0.48)[/tex]
[tex]P(ABC^c) = 0.48 * 0.48 * 0.52[/tex]
[tex]P(ABC^c) = 0.119808[/tex]
Solving (c): [tex]P(AB^cC)[/tex]
This is calculated as:
[tex]P(AB^cC) = P(A) * P(B^c) * P(C)[/tex]
[tex]P(AB^cC) = P(A) * [1 - P(B)] * P(C)[/tex]
[tex]P(AB^cC) = 0.48 * (1 - 0.48)* 0.48[/tex]
[tex]P(AB^cC) = 0.48 * 0.52* 0.48[/tex]
[tex]P(AB^cC) = 0.119808[/tex]
Solving (d): [tex]P(A^cBC)[/tex]
This is calculated as:
[tex]P(A^cBC) = P(A^c) * P(B) * P(C)[/tex]
[tex]P(A^cBC) = [1-P(A)] *P(B) * P(C)[/tex]
[tex]P(A^cBC) = (1 - 0.48)* 0.48 * 0.48[/tex]
[tex]P(A^cBC) = 0.52* 0.48 * 0.48[/tex]
[tex]P(A^cBC) = 0.119808[/tex]
Solving (e): [tex]P(AB^cC^c)[/tex]
This is calculated as:
[tex]P(AB^cC^c) = P(A) * P(B^c) * P(C^c)[/tex]
[tex]P(AB^cC^c) = P(A) * [1-P(B)] * [1-P(C)][/tex]
[tex]P(AB^cC^c) = 0.48 * [1-0.48] * [1-0.48][/tex]
[tex]P(AB^cC^c) = 0.48 * 0.52*0.52[/tex]
[tex]P(AB^cC^c) = 0.129792[/tex]
Solving (f): [tex]P(A^cBC^c)[/tex]
This is calculated as:
[tex]P(A^cBC^c) = P(A^c) * P(B) * P(C^c)[/tex]
[tex]P(A^cBC^c) = [1-P(A)] * P(B) * [1-P(C)][/tex]
[tex]P(A^cBC^c) = [1-0.48] * 0.48 * [1-0.48][/tex]
[tex]P(A^cBC^c) = 0.52 * 0.48 * 0.52[/tex]
[tex]P(A^cBC^c) = 0.129792[/tex]
Solving (g): [tex]P(A^cB^cC)[/tex]
This is calculated as:
[tex]P(A^cB^cC) = P(A^c) * P(B^c) * P(C)[/tex]
[tex]P(A^cB^cC) = [1-P(A)] * [1-P(B)] * P(C)[/tex]
[tex]P(A^cB^cC) = [1-0.48] * [1-0.48] * 0.48[/tex]
[tex]P(A^cB^cC) = 0.52 * 0.52 * 0.48[/tex]
[tex]P(A^cB^cC) = 0.129792[/tex]
Solving (h): [tex]P(A^cB^cC^c)[/tex]
This is calculated as:
[tex]P(A^cB^cC^c) = P(A^c) * P(B^c) * P(C^c)[/tex]

[tex]9 + \frac{n}{3} - 6 = 7[/tex]
Your answer is 7,
Known:n=12
So 12/3
First, we need to simplify 12/3
To simplify this, all we need to do is divide 12 by 3
12÷3=4
3 goes into 12 4 times.
So now our eqation is
9+4-6
9+4 is 13
13-6 is 7
