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.
Answers
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
13) Find the values of x and y.
Answers
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°

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?
Answers
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) = _____
Answers
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]

Solving (g): [tex]P(A^cB^cC)[/tex]
This is calculated as:

Give your answer rounded to 2 DP.
Answers
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

3. Technology required. Gateway Arch in St. Louis, Missouri, is 630 feet tall. Priya can look
up at a 50 degree angle to see the top of the arch. How far away from the base of the
arch is she standing?
Answers
x = 630/tan(50°) = 528 ft
Priya is standing 528.63 feet away from the base of Gateway Arch in St. Missouri.
What is trigonometry?In the field of mathematics known as trigonometry, correlations between angles and length ratios are studied. The field was created in the Hellenistic era in the third century BC as a result of the use of geometry in astronomical research.
Given parameters:
Height of the Gateway Arch in St. Missouri = 630 feet.
Priya have to look up at a 50° angle to see the top of the arch.
Now from definition of tanθ in trigonometry:
tan50° = height of the Gateway Arch in St. Missouri ÷ distance of Gateway Arch in St. Missouri
hence, distance of Gateway Arch in St. Missouri = height of Gateway Arch in St. Missouri ÷ tan50°
= 630 feet ÷ tan50°
= 528.63 feet.
Hence, she is standing 528.63 feet away from the base of Gateway Arch in St. Missouri.

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?
Answers
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.

Find the y-intercept of a line parallel to 8x – 2y = 12 and passes through the point (5, 3).
Answers
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.
